Your first Dublin tenancy will be the most legally protected thing you sign all decade — if you know where the protections are. The deposit you hand over is capped by law at one month’s rent. The rent can only rise once a year, by the lower of inflation or 2%. And the notice you must give — or the notice your landlord must give you — is a published table, not a mood. First-time renters lose money in only two ways: not knowing the caps before they pay, and not knowing the deadlines after something goes wrong. This guide closes both gaps.
It is the tenant-rights chapter of our Dublin renting guide, written for the person renting in Dublin for the first time — here, we cover the law that applies after you have found the place. Finding and winning the place is our separate step-by-step rental application playbook. All legal rules below were verified against RTB, Citizens Information and Threshold guidance on 5 September 2026.
1. The deposit: what you can be asked to pay, and what happens to it
The two caps that protect your cash
- A deposit cannot be more than one month’s rent. “A landlord cannot ask for a deposit that is more than one month’s rent” (RTB — security deposits). Two months’ rent as a deposit is unlawful.
- Total upfront payments are capped at two months’ rent — that is, a one-month deposit plus one month’s rent in advance. This applies to all tenancies created since 9 August 2021 under the Residential Tenancies (No. 2) Act 2021 (Citizens Information — tenants’ rights and responsibilities). Student-specific accommodation has only a narrow opt-out (where rent and tuition go to the same provider).
So the most a legitimate landlord or agent can ask for on day one, for a typical private tenancy, is deposit (one month) + first month’s rent. Anything on top — “holding fees,” “admin fees,” “key money,” a “viewing deposit” — is a red flag. Scamwatch is simple: never pay anything to someone who will not let you view the property first (Threshold — how to spot a scam).
Pay by traceable means (bank transfer), not cash, and get a signed, dated receipt stating what was paid and what it is for. If an agent holds the deposit, get the landlord’s contact details in writing at the same time — you need to know exactly who holds your money when the tenancy ends (RTB — security deposits).
The four lawful reasons a landlord can keep part (or all) of it
At the end of the tenancy the deposit must be returned unless there is a legal reason to deduct. The closed list is (RTB — security deposits; Citizens Information):
| Reason to deduct | What it means for you |
|---|---|
| Rent arrears | Rent owed up to the day you leave can come out of the deposit. |
| Unpaid bills | Gas, electricity or other bills you were responsible for under the tenancy agreement and did not pay. |
| Damage above normal wear and tear | Broken windows, holes in walls, missing or broken items from the inventory, or leaving the property unhygienic. Normal wear and tear — the gradual deterioration from ordinary use — is the landlord’s cost, never yours. |
| Insufficient notice | Leaving without the correct notice, or breaking a fixed-term lease early (see Section 4). |
That list is exhaustive. “Cleaning fees,” “redecorating because we feel like it,” and “general wear” are not on it. If the landlord claims damage, ask for receipts or invoices showing the actual repair cost — Threshold advises tenants to demand documentary evidence for every claimed deduction (Threshold — get deposit back). Your landlord cannot hold your belongings hostage against money they claim you owe (RTB).
How quickly should it come back?
There is no fixed number of days in legislation — the law says the deposit must be returned promptly and “as soon as possible” when the tenancy ends, allowing the landlord reasonable time to inspect (RTB — security deposits; Citizens Information). In practice, Threshold recommends the deposit be returned within 14 days of the tenancy ending under normal circumstances (Threshold — get deposit back). If two to three weeks pass with silence and no itemised statement, chase it in writing (email is fine) — a written trail is what you need if the dispute ends up at the RTB.
Callout — protect the deposit before you move in
The single best deposit-protection tool is the inventory: your landlord must give you one listing the contents and their condition (Citizens Information). Go through it room by room at move-in, photograph and video everything — marks, chips, stains, meter readings — and agree the condition in writing with the landlord. At move-out, repeat it. The difference between a returned deposit and a “damage” deduction is almost always photographic evidence of the starting condition.
Note: Ireland has legislated for a State-run tenancy deposit protection scheme (where the RTB would hold deposits), but those provisions are not yet in operation (Citizens Information). For now your deposit sits with the landlord or agent, which is exactly why the receipt, the inventory and the paper trail matter.
RTB registration: not optional, and your rights depend on it
Your landlord must register the tenancy with the RTB within one month of the tenancy starting, and since 4 April 2022 must re-register it every year while the tenancy continues (within a month of the anniversary). The fee is €40 per year for a private tenancy, with late fees of €10 per month (Citizens Information — registering a tenancy). Registration is how the State knows your tenancy exists — and the RTB’s public register lets you confirm an address is registered (RTB — check the register).
Why you care:
- Ask to see the registration, or check it yourself. You also have the right to request a copy of the RTB registration record for your own tenancy (Citizens Information — tenants’ rights). An unregistered tenancy is a landlord breaking the law — fines run to €4,000 plus per-day penalties on criminal conviction, or RTB sanctions up to €15,000 (Citizens Information).
- You can use the RTB dispute service even if your landlord never registered; they cannot. Landlords must be registered to bring or defend a case at the RTB — tenants can use the service regardless (Citizens Information — disputes). An unregistered landlord is therefore at a structural disadvantage if you ever dispute the deposit.
- The register also shows the previous rent on the property; separately, the RTB Rent Register (public since 1 March 2026) lets you benchmark rents in the area. Threshold’s tip: ask the RTB for the last registered rent on a specific property before you sign (Threshold — new rental rules).
2. Lease types and how long you can actually stay
Fixed-term vs periodic — the two shapes of a Dublin lease
Fixed-term tenancy (the standard Dublin first lease). You agree to rent for a set period — in Dublin, almost always 12 months; six-month terms exist but are less common (Citizens Information — if a tenant wants to end a tenancy). During the fixed term you are committed: you cannot leave early just because you found somewhere better. Break a fixed term and you can lose your deposit and be liable for rent for the months remaining — even if the landlord finds a replacement tenant. The exceptions are narrow (Section 4).
Periodic tenancy. When a fixed term ends and you stay on, or if you rent with no fixed term at all, the tenancy rolls on — usually month-to-month. Either side can end it by giving the correct statutory notice. Many tenants wrongly believe a 12-month lease evaporates at month 12; it does not — unless either side serves a valid notice, you roll into a periodic tenancy with all your security of tenure intact.
Your first 6 months, and the security that follows
Irish tenancy law deliberately creates a 6-month probation period: for the first six months, a landlord can end the tenancy without giving a reason (though since 1 March 2026 they must still serve a valid notice of termination and copy it to the RTB). After six months of continuous occupation, security of tenure attaches automatically — and from that point your landlord can only end the tenancy for a closed list of statutory reasons (Citizens Information — if your landlord wants you to leave).
What “after 6 months” means depends on when your tenancy began — the rules were rewritten for tenancies starting on or after 1 March 2026 (Residential Tenancies (Miscellaneous Provisions) Act 2026, which replaced the old rent-pressure-zone era rules):
| Tenancy started | Your right to stay | What protects you |
|---|---|---|
| On/after 1 March 2026 | Tenancy of Minimum Duration — up to 6 years once you pass 6 months, renewing in 6-year cycles | Landlord can only end it for specific reasons, which depend on landlord size (see below) |
| 11 June 2022 – 28 Feb 2026 | Tenancy of unlimited duration after 6 months | Landlord can only end for specific statutory reasons |
| 25 Dec 2016 – 10 June 2022 | Part 4 tenancy in 6-year cycles, becoming unlimited duration if not ended | After 6 years the landlord could once end for any reason; by June 2028 all such tenancies will have converted to unlimited duration |
(Citizens Information — types of tenancy)
The old term you will still hear — “Part 4 tenancy” — describes security of tenure that starts after 6 months. Under the 2026 rules, a larger landlord (a registered company, or anyone with 4+ tenancies) can end a Tenancy of Minimum Duration only if you breach your obligations or the property no longer suits your needs. A smaller landlord (1–3 tenancies) has a few extra grounds during the 6-year cycle — genuine hardship, or needing the home for themselves or an immediate family member — and more again (sale, substantial refurbishment, change of use) at the end of a 6-year cycle (Citizens Information). In plain terms: after 6 months in a post-March-2026 tenancy, a company or portfolio landlord essentially cannot end your tenancy without a breach on your side.
Tenancies the law does not protect (know which one you are in)
- Renting a room in your landlord’s own home (non-self-contained) makes you a licensee, not a tenant — the Residential Tenancies Act does not cover you, you have no RTB dispute rights, and a deposit dispute goes to the Small Claims Court (€25) instead (Threshold — I am a tenant; Threshold — get deposit back). A self-contained flat in the landlord’s home is covered.
- Student-specific accommodation (SSA) is covered by the legislation but with different rules: no security of tenure, a flat 28 days’ notice when leaving, fixed terms usually capped at 41 weeks, and a window between 1 May and 1 October each year when you can end a fixed term for any reason (Citizens Information).
3. Rent reviews: the 2026 rules that cap your rent
Rent increases are the most complained-about area of Irish renting, and also the most strictly regulated since the March 2026 reform. The short version for a first-time tenant:
- One review per 12 months. During a tenancy, rent can only be reviewed once in any 12-month period, and any increase applies only from the date in the notice — it cannot be backdated.
- The increase is capped at the lower of CPI inflation or 2%. Since 1 March 2026 this single national cap applies to every private tenancy in Ireland — the old rent pressure zones are gone. With CPI at 3.4% in the year to July 2026, the effective cap right now is 2% (CSO — CPI July 2026). On a €1,900 rent, that is a maximum rise of €38 — to €1,938.
- A mid-tenancy “market rent” increase is never allowed. While you stay, only the capped increase applies. Market rent can only be set at a genuine new tenancy (or, for post-March-2026 tenancies, at the end of a 6-year cycle) — and never after a no-fault termination of your tenancy.
- The notice is 90 days, and the RTB must get a copy the same day. A valid rent review needs a completed RTB Notice of Rent Review form served on you and filed with the RTB on the same day, at least 90 days before the new rent takes effect. No same-day RTB copy = the notice is invalid and the increase cannot lawfully happen. The landlord must also update the RTB tenancy registration with the new rent within a month.
- New apartments are the one exception: homes where construction commenced on or after 10 June 2025 can rise each year by CPI with no 2% ceiling — the deliberate trade-off for new supply.
Use the official RTB Rent Calculator to check any notice you receive, and the public RTB Rent Register (live since 1 March 2026) to benchmark what the notice claims. If your landlord overcharges, you can challenge the notice in writing, get free advice from Threshold on 1800 454 454, and refer the dispute to the RTB before the increase starts; where the RTB upholds a complaint it can stop the increase, order repayment, and award damages of up to €20,000.
The full mechanics — including the CPI-versus-2% worked example and how to check a notice step by step — are in our dedicated explainer: RPZs Are Gone: The New National 2% Rent Cap in Ireland, Explained (2026).
4. Notice periods: the table that ends tenancies cleanly
Notice periods are where first-time renters lose deposits — by leaving too early, or leaving the wrong way. Here is the statutory table that applies to you, the tenant, when you end a periodic tenancy (or give notice to leave at the end of a fixed term) (Citizens Information — if a tenant wants to end a tenancy; RTB — how a tenant can end a tenancy):
| How long you have been renting | Minimum notice you give your landlord |
|---|---|
| Less than 6 months | 4 weeks (28 days) |
| 6 months to 1 year | 5 weeks (35 days) |
| 1 to 2 years | 6 weeks (42 days) |
| 2 to 4 years | 8 weeks (56 days) |
| 4 to 8 years | 12 weeks (84 days) |
| 8 years or more | 16 weeks (112 days) |
(Student-specific accommodation: a flat 28 days. If you are leaving because your landlord has broken their obligations and not fixed the issue in a reasonable time, you can give 28 days — or 7 days if the landlord’s behaviour creates an imminent danger to life or safety. If a private landlord refuses permission to assign or sublet, you may treat the tenancy as ended — Section 7.)
Notice must be valid, not just sent
An email or text saying “I’m leaving” is not enough. A valid notice of termination from a tenant must be in writing, signed, dated, state the date the tenancy will end (you have the full 24 hours of that date to leave), and state that the landlord can refer any dispute about the notice’s validity to the RTB within 28 days of receiving it (90 days where no breach of obligations is alleged) (Citizens Information; RTB). Use the RTB’s sample notice template rather than inventing your own — a notice that fails the formalities is how a landlord keeps your deposit for “insufficient notice.”
Fixed-term early exit: the exceptions only
If you are in a 12-month fixed term, you cannot simply give notice and leave. The exceptions (RTB; Citizens Information):
- A break clause in your lease — use it exactly as written.
- Your landlord agrees — get the release in writing.
- Landlord breach — your landlord has not met their obligations (e.g., repairs) and has not fixed the issue within a reasonable time: 28 days’ notice.
- Serious risk — imminent danger to life, serious injury or the structure of the property: 7 days’ notice.
- Refusal of assignment/subletting by a private landlord.
Otherwise, leaving early means you may lose your deposit and remain liable for the rent to the end of the term. If a job move or a purchase is even possible, negotiate a break clause before signing.
What your landlord must give you (the other side of the table)
If your landlord wants you out, the rules are tighter — and since 6 July 2022 the notice periods a landlord must give are far longer than a tenant’s (Citizens Information — if your landlord wants you to leave):
| Length of tenancy | Minimum notice the landlord must give |
|---|---|
| Less than 6 months | 90 days |
| 6 months to under 1 year | 152 days |
| 1 year to under 7 years | 180 days |
| 7 years to under 8 years | 196 days |
| 8 years or more | 224 days |
The exceptions are narrow. A landlord ends with only 28 days’ notice if you are in breach of your obligations (after a written warning that gives you a reasonable time to fix the issue — and the warning must be copied to the RTB), or after the rent arrears process (a written arrears warning giving you 28 days to pay, copied to the RTB, then a 28-day notice if you do not pay). Serious anti-social behaviour or behaviour threatening the property: 7 days’ notice, no warning required (Citizens Information).
And a landlord’s notice is only valid if it meets the same formalities in mirror image — in writing, signed, dated, with the termination date — and a copy is sent to the RTB at the same time it reaches you. As of the date of writing, same-day service of the RTB copy is required; from 14 September 2026 the landlord will have 7 days to send the RTB copy, and will no longer be able to rely on posting the notice to you (email or hand delivery becomes the norm) (Citizens Information). A notice with no RTB copy is invalid.
Your right to challenge. If you believe a notice is invalid or the reason is not allowed, you have 90 days from receiving the notice to refer the dispute to the RTB (28 days if you are in breach of your own obligations). If you win, the notice falls and the tenancy continues (Citizens Information — disputes). Threshold will review a notice of termination for free on 1800 454 454 before you act on it.
Your right to return. If your landlord ends the tenancy to sell, and no sale agreement is signed within 9 months of the notice period ending, they must offer the property back to you. The same right applies if a family member moved in and the home is re-let within 12 months, if the use changed and it is re-let within 12 months, or if a “substantial refurbishment” ends with the property back on the rental market (Citizens Information; RTB — how a landlord can end a tenancy).
5. Repairs: who fixes what, and the standards your home must meet
The landlord’s obligations: everything structural, and the standards
Your landlord must keep the property in a state that complies with the Housing (Standards for Rented Houses) Regulations 2019 and with the repairing obligations in the Residential Tenancies Act. In plain terms, the landlord is responsible for (Citizens Information — minimum standards):
| Area | What the landlord must keep in order |
|---|---|
| Structure & exterior | Roof, slates, windows, walls, floors, ceilings, stairs, doors, gutters and downpipes — no damp, structurally sound inside and out |
| Services | Electricity and gas safe and in good repair; plumbing; water supply (hot and cold); heating you can control in every room |
| Sanitary facilities | A toilet, washbasin and fixed bath/shower with hot and cold water, maintained and ventilated, with a fixed heater |
| Ventilation & light | Adequate ventilation and natural and artificial lighting in every room |
| Safety | Fire detection and alarm system, fire blanket, carbon monoxide alarm, window safety restrictors above ground level, vermin/pest-proof rubbish storage |
| Kitchen & laundry (private lets) | 4-ring hob, oven and grill, extractor hood, fridge-freezer, microwave, adequate storage, sink with hot and cold water — plus a washing machine, and a dryer if there is no private garden or yard |
If you rent a house that is freezing because the heating is broken, or an apartment with water coming through the ceiling, that is not “bad luck” — it is a breach of the landlord’s statutory obligations. The enforcement route if the landlord refuses to fix serious problems: tell the landlord in writing first, then complain to your local authority (the Environmental Health Service enforces the minimum standards and can issue Improvement Notices and, ultimately, Prohibition Notices stopping the home being re-let), and separately pursue the landlord through the RTB for breach of obligations (Citizens Information).
The tenant’s obligations: keep it in good order, report it, allow access
Your side of the repair bargain is genuinely light, but it is enforceable (Citizens Information — tenants’ responsibilities):
- Keep the property in good order — clean, rubbish disposed of, no damage caused by you or your visitors.
- Report repairs promptly in writing, and allow the landlord access (by appointment) to carry them out.
- Tell the landlord who is living in the property, and give the information needed for RTB registration.
- Pay the rent and any charges the tenancy agreement assigns to you (utilities, waste, agreed management fees).
Two practical notes: normal wear and tear is never your bill — a landlord cannot charge you for the carpet wearing or paint ageing. And if you pay out of pocket for a repair that is the landlord’s responsibility, you are entitled to be reimbursed (Citizens Information). Your landlord can only enter your home with your permission — arrange inspections in advance, and viewings (if the property is being sold) must be agreed with you beforehand; emergency access excepted. As a tenant you are not expected to insure the building — that is the landlord’s job — but your contents are not covered by the landlord’s policy, so contents insurance is your call (Citizens Information).
6. Disputes: the RTB process, the time limits and the (free) first step
The order of escalation
- Talk to the landlord in writing — most disputes (a withheld deposit, a disputed notice, a repair) are calculation errors or misunderstandings, and a clear email fixes many of them.
- Threshold, free — 1800 454 454 (Mon–Fri, 9am–9pm). Independent, confidential tenancy advice before you spend a cent or serve anything (Threshold).
- The RTB dispute resolution service — the statutory forum that replaces the courts for most landlord–tenant disputes. You do not need a solicitor, and hearings are informal and mostly online (Citizens Information — disputes).
How the RTB process works
- Stage 1 — mediation or adjudication. When you apply, the RTB will generally try mediation first: a neutral mediator works with both sides (by phone or video) to reach an agreement you both accept. Mediation is free and its outcomes are confidential (Citizens Information). If mediation fails or either side refuses it, the case goes to adjudication: an adjudicator hears both sides with evidence and issues a determination order — a legally binding decision. Adjudication costs €30 online. Agreed or adjudicated outcomes become binding determination orders, usually issued within about two weeks.
- Stage 2 — the RTB Tribunal. Either side can appeal an adjudicator’s decision (or a failed mediation) to a three-person Tribunal within 10 days of the decision. Tribunal hearings are public but informal, and you can represent yourself. Fees: €30 to appeal a mediated outcome, €85 to appeal an adjudicated decision. A Tribunal decision can only be appealed further to the High Court on a point of law, within 21 days (Citizens Information).
- Enforcement. RTB determination orders are legally binding; if the other side does not comply, the order is enforced through the District Court.
Time limits — do not miss them
| Dispute type | Time to refer it to the RTB |
|---|---|
| Rent / money owed at the end of the tenancy (including your deposit) | Within 28 days of the tenancy ending |
| A notice of termination from your landlord | Within 90 days of getting the notice (if you have kept your obligations); 28 days if you have broken them |
| A rent increase | Before the increase is due to start (you must get 90 days’ notice), or within 28 days of receiving the formal rent review notice |
(Citizens Information — disputes)
The RTB can extend these limits in exceptional circumstances — but do not rely on that. The 28-day window after your tenancy ends is the one that catches former tenants: if your deposit has not arrived three weeks after you moved out, start the written chase immediately so the clock is documented, and file with the RTB inside the window if the landlord is silent. One exception worth knowing from the rent rules: where a rent-increase notice was invalid (for example, no same-day RTB copy), there is no time limit to dispute it.
Two rules that keep you safe during any dispute: never withhold rent (it hands the landlord a breach-based termination and weakens your own case), and remember that you can use the RTB even if your landlord never registered the tenancy — they cannot (Citizens Information). You can also report a landlord who is breaking rental law to the RTB’s investigations and sanctions unit rather than pursuing a personal dispute.
7. Subletting and assignment: what you can and cannot do with your lease
Dublin rent is high, and the temptation to “rent out” your place — or to hand a lease to a friend — is real. The rules matter because getting them wrong can cost you your tenancy.
Subletting means you rent the property (or part of it) to someone else while you remain the tenant: you stay responsible to the landlord, and your sub-tenant answers to you. Assignment means you transfer the whole tenancy to someone else, who becomes the landlord’s tenant in your place and you walk away (RTB — subletting and assignment).
| Subletting | Assignment | |
|---|---|---|
| What happens | You stay as head-tenant; sub-tenant pays you | New person replaces you entirely |
| Permission needed | Landlord’s written consent | Landlord’s consent |
| Your liability | You remain fully responsible to the landlord | You drop out of the tenancy |
| RTB registration | Head-tenant must register the sub-tenancy (RTB1 paper form) | Tenancy continues/transfers with RTB update |
| Allowed in SSA / AHB / cost rental? | No | No |
The rules that matter to a first-time renter:
- Both subletting and assignment require your landlord’s permission. Subletting without consent is a breach of your tenant obligations and can lead to a valid termination against you. If a landlord refuses consent to an assignment or sublet (and it is a private landlord), the law gives you an exit: you can end the tenancy by serving a notice of termination — one of the few ways out of a fixed term (RTB; Citizens Information).
- A flatmate is not a subtenant. Sharing the property and its facilities with someone who lives there with you is not subletting — no landlord consent is required. But tell your landlord who is living in the property, and check your lease: if someone moves in permanently, your landlord must be informed, and the rent and bills split is between you and your housemate, not the landlord (RTB; Citizens Information).
- An illegal sub-tenancy is unprotected. If your landlord does not know about the sub-tenancy, the RTB may not be able to deal with disputes arising from it through its dispute resolution or investigation functions (RTB). If you sublet without consent, you carry all the risk and your “tenant” carries none of the statutory protections.
- Assignment and your security of tenure. If a Part 4 / security-of-tenure tenancy is assigned to a newcomer, the assignee must live in the property for 6 months before gaining their own security of tenure (RTB).
The clean alternative to both: if you need to leave a fixed term early, use Section 4’s route — agree a release with the landlord, use a break clause, or negotiate that the landlord markets the property with you cooperating (the landlord cannot double-charge: if they re-let, their duty to mitigate means they cannot simply collect your rent and the new tenant’s).
8. The first-viewing checklist: what to check before you hand over a euro
Everything in this guide is easier if you screen the property and the paperwork before you commit. Print this list and take it to every viewing:
Documents and identities to ask for
- [ ] RTB registration — ask to see proof the tenancy will be (or is) registered; confirm you can check it on the RTB register.
- [ ] The landlord’s name and contact details — always, even when an agent is managing (RTB — security deposits).
- [ ] BER certificate — the Building Energy Rating (Ireland’s energy certificate — the EPC equivalent). Every rental home must have one, and the rating drives your heating bills and is a filter on the RTB Rent Register. Ask the rating outright: a G-rated house can cost you hundreds more a year than a B-rated one (Citizens Information).
- [ ] The inventory — confirm one exists and will be agreed in writing at move-in (Section 1).
- [ ] The lease itself before you pay — read the fixed term, the rent-review clause, the bills included, the break-clause position, and anything about visitors, pets or parking. The lease cannot override your statutory rights, but it sets everything the law does not cover.
The property itself
- [ ] Photos and video of everything — walls, floors, windows, fixtures, appliances, meter readings. Time-stamped evidence is your deposit insurance.
- [ ] Test the systems — run taps (hot and cold), flush toilets, turn on the heating and radiators, test the shower pressure, open windows. A viewing is your only chance to find problems while you still have leverage.
- [ ] Sniff for damp and look for mould — behind furniture, on ceilings, around windows. Damp is both a health issue and the most common “it was already there” deduction dispute.
- [ ] Check the appliances that must be provided (cooker, fridge-freezer, washing machine) and ask what happens if one breaks mid-tenancy.
- [ ] Fire and CO safety — alarms present and working? Fire blanket in the kitchen? (Landlord obligations under the minimum standards, Section 5.)
The money questions
- [ ] Deposit and upfront confirmed in writing — deposit ≤ 1 month, total upfront ≤ 2 months’ rent (Section 1). Anything above that is unlawful, not negotiable.
- [ ] What the rent includes — heating, electricity, gas, bins, parking, broadband; and what the rent register shows the previous rent was (Threshold).
- [ ] How the deposit is returned — who holds it, the notice period you must give, and the move-out process. Get it in the lease if it is not there.
- [ ] Nothing paid before a viewing — ever. Paying a stranger to “hold” a place you have not seen is how rental scams work (Threshold).
9. Frequently asked questions
1. What are my rights when renting in Ireland for the first time?
The essentials: your deposit is capped at one month’s rent and total upfront at two months; the tenancy must be registered with the RTB; rent can only rise once a year by the lower of inflation or 2% (with 90 days’ notice and a same-day RTB copy); after 6 months you gain security of tenure and can only be removed for a closed list of statutory reasons with long notice periods; and your home must meet the minimum standards regulations, with the landlord responsible for structure, services and repairs (Citizens Information).
2. Can a landlord ask for two months’ deposit in Ireland?
No. A deposit cannot exceed one month’s rent, and total upfront payments (deposit plus advance rent) are capped at two months’ rent for tenancies created since 9 August 2021 (RTB — security deposits; Citizens Information).
3. How long does a landlord have to return my deposit?
The law says “promptly” and “as soon as possible” — there is no fixed statutory day-count, but the RTB expects the landlord to need only reasonable time to inspect, and Threshold recommends return within 14 days of the tenancy ending. Deductions are allowed only for rent arrears, unpaid bills you owed, damage beyond normal wear and tear, or insufficient notice — and you should demand receipts for any claimed damage (Threshold — get deposit back; RTB).
4. How much notice does a tenant have to give in Ireland?
It depends on how long you have rented: 28 days under 6 months; 35 days at 6 months–1 year; 42 days at 1–2 years; 56 days at 2–4 years; 84 days at 4–8 years; and 112 days after 8 years (student accommodation: 28 days). The notice must be a valid written, signed, dated notice of termination — see the full table in Section 4 (Citizens Information).
5. Can my landlord increase the rent by more than 2% in 2026?
Only if CPI is below 2% (then the cap is the lower CPI figure), or for qualifying new apartments (construction started on or after 10 June 2025) which can rise by CPI with no 2% ceiling. With CPI at 3.4%, the current cap for an existing tenancy is 2% — and any increase needs 90 days’ notice with the notice filed with the RTB the same day. Full mechanics in our rent cap explainer.
6. Can my landlord end the tenancy in the first six months?
Yes — in the first 6 months a landlord can end the tenancy without giving a reason, but they must still serve a valid notice of termination (copied to the RTB). After 6 months you have security of tenure and they need one of the statutory grounds, with notice periods of 90–224 days depending on your tenancy length (Citizens Information).
7. What do I do if my landlord won’t fix the heating or repairs?
Write to the landlord first, giving a reasonable time to fix the issue (keep a copy). If nothing happens: contact your local authority’s Environmental Health Service (they enforce the minimum standards regulations and can issue improvement/prohibition notices), get free advice from Threshold on 1800 454 454, and refer the landlord’s breach of obligations to the RTB. Do not withhold rent while you wait (Citizens Information — minimum standards).
8. Can I sublet my Dublin apartment?
Only with your landlord’s written permission — and never in approved housing body, student-specific or cost-rental accommodation. Subletting without consent is a breach of your tenancy. Having a flatmate share with you is not subletting, but tell your landlord who lives there. If a private landlord refuses permission to assign or sublet, you can end the tenancy (even a fixed term) with a notice of termination (RTB — subletting and assignment).
9. How much does it cost to take a dispute to the RTB, and do I need a solicitor?
Mediation is free. Adjudication costs €30 online; appealing a mediated outcome to the Tribunal costs €30, and appealing an adjudicated decision costs €85. You do not need a solicitor at any stage — the RTB replaces the courts for most tenancy disputes, hearings are informal, and determination orders are legally binding (Citizens Information — disputes).
10. I rent a room in my landlord’s home — do I have tenant rights?
If the room is not self-contained, you are a licensee, not a tenant: the Residential Tenancies Act does not cover you, you cannot use the RTB dispute service, and a deposit dispute goes to the Small Claims Court (€25). A self-contained flat in the landlord’s home is covered by the legislation (Threshold; Citizens Information).
10. Bottom line: the five numbers that run your first Dublin tenancy
- € — one month’s deposit, two months’ total upfront. Never pay more; never pay before a viewing; always get a receipt and a written inventory (RTB).
- 6 months — when security of tenure attaches. Survive the first six months without a valid notice and the landlord’s power to remove you collapses to a short list of statutory reasons (Citizens Information).
- 2% — the current rent cap, with 90 days’ notice and a same-day RTB copy; one review per 12 months (RTB Rent Calculator).
- 28 to 112 days — the notice you owe, scaled to how long you have lived there; a fixed term needs a break clause, a mutual release, or one of the narrow statutory exits (Section 4).
- 28 days — the clock after you leave. Deposit disputes and end-of-tenancy money claims go to the RTB within 28 days of the tenancy ending; mediation is free and you can represent yourself.

Legal rules verified against RTB, Citizens Information and Threshold guidance on 5 September 2026. This guide summarises residential tenancies law for general information — it is not legal advice. If a specific dispute arises, use the free services above (Threshold, the RTB, your local authority) before acting. Two dates to watch: the landlord’s rent-review and termination-notice rules changed on 1 March 2026, and from 14 September 2026 landlords gain 7 days (instead of same-day) to file termination notices with the RTB.
