The Accidental Landlord: Letting a Home You Didn't Plan To

Plenty of people become landlords without planning to: you inherit a house, you cannot sell so you let instead, you move in with a partner, or you relocate for work and keep the old home. The law treats you the same as any landlord. You must register the tenancy with the RTB, meet minimum standards, have a BER, follow the deposit and notice rules, and pay tax on the rent. None of it is optional, so go in with eyes open, then decide whether letting is really better than selling.

If you find yourself renting out a property you did not set out to rent, the most important thing to know is that "accidental" has no legal meaning. You have all the duties of a professional landlord from day one.

What you must do

• Register the tenancy with the RTB. Register within one month of the tenancy starting, and again every year while it continues. The basic fee is €40 a year. Not registering can be fined up to €4,000, and registration is also a condition of deducting your mortgage interest against the rent.
• Meet minimum standards. The property must be structurally sound, free of damp, and have hot and cold running water, working heating, and the required facilities. The RTB sets the full list, and repairs are your responsibility.
• Have a BER. Every rental home must have a valid Building Energy Rating to advertise and let it.
• Follow the money rules. You cannot take more than two months' rent upfront (typically a deposit plus the first month), and you must return the deposit promptly at the end, minus only legitimate deductions (unpaid rent, bills, or damage beyond normal wear and tear).
• Respect the tenant's rights. The tenant is entitled to peaceful, exclusive occupation, so you can only enter with their permission except in an emergency. You must also comply with equality law, including not refusing a tenant because they receive a State housing payment such as HAP.
• Pay tax on the rent. Rental income is taxable at your marginal rate plus USC and PRSI, declared through self-assessment (Form 11 if your net non-PAYE income is over €5,000). See the buy-to-let guide for the deductions and the pay-and-file deadline.

Ending it later is not instant

If you need the property back, you cannot simply ask the tenant to leave. Notice periods are scaled to how long they have rented, and the grounds and procedure are tightly defined. Rent arrears, for example, require a two-stage process. See the ending-a-tenancy guide before you make plans that depend on getting the property back by a certain date.

Let or sell? A quick framework

Before defaulting to letting, weigh it honestly: - Letting brings income but also responsibility, cost (insurance, maintenance, agent fees, tax), and the reality that you may not get the property back quickly. It suits you if you want to hold the asset long term, or you expect to return to the home yourself. - Selling ends the responsibility and frees the capital. If it is your former main home, Principal Private Residence relief usually means little or no CGT, though that relief erodes the longer you let it. See the capital-gains-tax-property and selling-your-home guides.
