Before Letting
Register with the RTB
All private residential tenancies must be registered with the Residential Tenancies Board within 30 days of the tenancy start date. Annual renewal is required since April 2022.
Ensure the property meets minimum standards
Properties must comply with the Housing (Standards for Rented Houses) Regulations 2019. This covers structural condition, heating, sanitation, ventilation, and fire safety requirements.
Obtain a BER certificate
A Building Energy Rating (BER) certificate is legally required before advertising a property for rent. The BER rating must be included in all advertising. Properties rated below B3 may face future restrictions.
Prepare a rent book (or digital equivalent)
Landlords must provide tenants with a rent book (or digital equivalent) that records rent payments. The rent book must include landlord details, property address, and the amount of rent due.
Provide written lease / tenancy agreement
While not always legally required, providing a written tenancy agreement setting out the terms is strongly advisable. Certain terms (tenancy start date, rent, duration) must be provided in writing.
Ongoing Obligations
Maintain the property in good repair
Landlords are legally obliged to keep the structure, exterior, and interior of the property in good repair throughout the tenancy. This includes the roof, walls, windows, plumbing, heating, electrical systems, and appliances provided by the landlord.
Carry out repairs promptly
When a tenant reports a repair need, the landlord must address it within a reasonable time. Urgent issues (e.g., no heating in winter, leak causing damage) must be prioritised. Failure to repair is grounds for an RTB dispute.
Give proper notice before entering the property
A landlord must give at least 24 hours' written notice before entering the property for inspections or non-urgent repairs. Entry should occur at a reasonable time and be agreed with the tenant.
Provide receipts for rent payments
If a tenant pays by cash, the landlord must provide a written receipt. For electronic payments, bank records serve as evidence, but keeping clear records is good practice.
Manage security deposits correctly
A deposit can be held by the landlord for the duration of the tenancy. It must be returned within a reasonable time of the tenancy ending, minus any legitimate deductions for unpaid rent or documented damage beyond fair wear and tear. RTB deposit protection rules are in development.
Renew RTB registration annually
Since April 2022, the RTB registration must be renewed each year by paying the annual fee. Failure to renew leaves the tenancy unregistered.
Rent Obligations
Only increase rent within the law
From 1 March 2026, national rent control applies to all private residential tenancies. Rent increases are capped at the lower of 2% per year or the CPI rate. A written Notice of Rent Review must be served at least 90 days before any increase takes effect. Rent can only be reviewed once every 12 months.
Set rent correctly for new tenancies
When letting to a new tenant, a market rent reset is permitted only in specific circumstances: if the previous tenant left voluntarily, breached obligations, or the property no longer suited their needs; at the end of a 6-year tenancy cycle; or if the property has not been let for 2 or more years. A market rent reset is not permitted after a no-fault landlord termination (sale, family occupation, refurbishment, or change of use).
Provide a rent book
The rent book must record all rent payments received, the landlord's name and address, and the property address. This is a legal requirement regardless of tenancy type.
End of Tenancy
Serve a valid notice of termination
A tenancy can only be ended by serving a valid written notice of termination with the correct notice period and, for Part 4 tenancies, a valid ground. Failure to comply with this process means the tenancy does not legally end.
Return the deposit promptly
The security deposit must be returned to the tenant within a reasonable period after the tenancy ends. Legitimate deductions must be documented and evidenced. Wrongful withholding of a deposit is grounds for an RTB dispute.
Comply with right of first refusal rules
If a tenancy is ended on grounds of sale and the property is not sold, or on grounds of family occupation and the property is re-let within the specified period, the landlord must offer the former tenant the right of first refusal.
Tax & Financial Obligations
Declare rental income to Revenue
All rental income must be declared on your annual Income Tax return (Form 11 for self-assessed taxpayers or Form 12 for PAYE workers with rental income). Failure to declare rental income is a Revenue offence.
Pay PRSI on rental income
From 2024, PRSI applies to rental income at the standard rate for self-employed landlords. Check with Revenue or an accountant for the current rate and rules.
Claim only permitted deductions
Allowable deductions against rental income include mortgage interest (75% deductible for non-HAP, 100% for HAP and LDA properties), repairs and maintenance, letting fees, and insurance premiums. Capital expenses are not deductible.
Register for LPT (Local Property Tax)
If you own a rental property, you must register it for Local Property Tax and pay the annual charge. The LPT is based on the property's market value band.
What Happens if a Landlord Fails to Meet Their Obligations?
RTB dispute
Tenants can refer breaches to the RTB. The RTB can issue determination orders and, if not complied with, sanctions up to €15,000 for landlords.
Local authority enforcement
Councils can inspect rental properties and serve improvement notices for breaches of minimum standards. Failure to comply can result in prosecution.
Revenue investigation
Failure to declare rental income can result in interest, penalties, and surcharges from Revenue. The Revenue has access to RTB registration data for cross-checking.
Loss of mortgage interest deduction
Landlords who are not registered with the RTB may lose their entitlement to deduct mortgage interest against rental income — potentially a significant financial penalty.

Frequently Asked Questions: Landlord Obligations Ireland
What are the main legal obligations of a landlord in Ireland?
The core obligations of an Irish landlord are: register each tenancy with the RTB within 30 days; maintain the property to minimum standards; provide a rent book; only increase rent within the law (national rent control cap of lower of 2% or CPI, 90-day notice, 12-month review cycle); give proper notice before entering; carry out repairs promptly; serve a valid notice of termination using the correct process (not by post, from 14 September 2026) and copy it to the RTB within 7 days of the date of service; return the deposit correctly; and declare all rental income to Revenue.
What are the minimum standards a rental property must meet in Ireland?
Under the Housing (Standards for Rented Houses) Regulations 2019, a rental property must have: a structurally sound interior and exterior; a fixed heating system capable of providing 70W per square metre in the main living area; hot and cold water supply; adequate ventilation; a kitchen area with cooking facilities, sink, and food storage; a bathroom with toilet, washbasin, and bath or shower; appropriate waste facilities; and working smoke and carbon monoxide alarms. Local councils can inspect properties and issue improvement notices.
Does a landlord have to provide a written lease in Ireland?
There is no absolute legal requirement to provide a written lease for all tenancies, but landlords must provide tenants with key tenancy information in writing within one month of the tenancy beginning. This includes the tenancy start date, rent amount, payment method, and property description. For practical and legal protection, a written lease is strongly advisable.
What is a BER certificate and is it required?
A BER (Building Energy Rating) certificate rates a property's energy efficiency from A1 (most efficient) to G (least efficient). It is legally required for all properties being let. The rating must be included in all advertising for the property. Landlords must arrange a BER assessment through a registered BER assessor. The certificate is valid for 10 years.
How long does a landlord have to return a deposit?
There is no specific statutory timeframe for deposit return in Ireland. The law requires return within a "reasonable time" after the tenancy ends. In practice, this is typically within 2–4 weeks. Deductions must be evidenced and justified. Wrongful withholding is grounds for an RTB dispute.
Can a landlord enter a rental property without notice?
No. A landlord must give at least 24 hours' written notice before entering the property for inspections or non-urgent repairs. The access time must be reasonable and agreed with the tenant where possible. Entering without proper notice breaches the tenant's right to peaceful enjoyment of the property and is grounds for an RTB dispute.
Are landlords liable for repairs in Ireland?
Yes. Landlords are legally obliged to maintain the structure and interior of the property — including the roof, walls, windows, plumbing, heating, and electrical systems — in good repair. Tenant-caused damage (beyond fair wear and tear) is the tenant's responsibility, but the structure and landlord-provided appliances are the landlord's responsibility to maintain.
What taxes do landlords pay in Ireland?
Rental income is subject to Income Tax at the marginal rate (20% or 40%). PRSI applies from 2024 at 4%. USC also applies. Local Property Tax (LPT) is payable annually. Mortgage interest is 75% deductible (or 100% for HAP/LDA properties). Capital Gains Tax applies on sale. Landlords should engage an accountant familiar with rental income to ensure compliance.
What happens if a landlord fails to meet their obligations?
Tenants can refer breaches to the RTB, which can issue determination orders requiring landlords to carry out repairs, return deposits, or comply with other obligations. Persistent non-compliance can result in fines and enforcement through the courts. For safety standard breaches, local councils can serve improvement notices and prosecute non-compliant landlords.
Does TenantSync help landlords stay compliant?
Yes. TenantSync provides an RTB compliance dashboard that tracks registration deadlines, annual renewals, tenancy cycles, Part 4 rights, and rent review schedules across all properties. It sends automated reminders before deadlines, helps generate compliant notices, and provides landlords with a clear view of their obligations at all times.
