Ronan's Story

How incorrect property comparisons overturned an unlawful rent increase in Galway

Ronan had been renting a two-bedroom apartment in the city centre of Galway for three years when his landlord issued a rent increase notice. The landlord claimed the increase was justified by market evidence — properties in the area had risen in value, he said, and the new rent reflected what similar properties were commanding. Ronan was unhappy with the increase, which would add several hundred euros to his yearly costs, but he wanted to understand whether his landlord's claim held water before taking action.

When Ronan looked at the evidence his landlord provided, he noticed something odd. The comparable properties listed weren't actually comparable at all. Some were three-bedroom properties — larger than his own apartment. Others were located on the other side of the city, in a different neighbourhood where rental prices were genuinely higher. None of them matched his actual property in size, condition, or location. Ronan realised that by picking properties that were either bigger or in pricier areas, his landlord had artificially inflated what the "market rent" supposedly was. This wasn't a fair way to calculate what his rent should be.

Ronan decided to challenge the increase. He gathered details of actual comparable properties — two-bedroom apartments of similar standard in his actual neighbourhood — and documented what they were genuinely renting for. His evidence showed that his existing rent was already at or above the true market rate for his property. When the matter was reviewed, it became clear that the landlord's comparison properties were simply not valid. The rent increase was overturned, and Ronan's rent remained where it was.

What the Law Says

Under Irish residential tenancy law, a landlord can only increase rent to the market rate, and only once every two years. Crucially, market rent must be calculated using evidence from comparable properties — properties that are genuinely similar in size, condition, location, and tenure. Using properties that are significantly different in any of these ways does not establish a valid market rent. If a rent increase is based on poor or misleading evidence of comparable properties, the increase can be challenged and overturned. The evidence must be genuine, relevant, and fair.

⏱️ Time Limits Matter

You have a limited window to challenge an unlawful rent increase. Landlords must give 90 days' notice before any rent increase takes effect. If you believe an increase is unlawful or unsupported by proper evidence, raise your concerns as soon as you receive notice — do not wait until the increase takes effect. Acting quickly preserves your rights and may prevent the unlawful increase from becoming established.
