Galway is covered by rent-control rules, so a landlord generally cannot increase rent more than once every 12 months and the increase is usually limited to the lower of 2% or inflation. The landlord must give at least 90 days’ notice and use the required rent-review information, including details of how the new rent was calculated. Different rules or limited exceptions can apply when a new tenancy begins or where the property qualifies for an exemption. Check the latest guidance on the RTB or gov.ie, as the outcome of any dispute depends on the individual tenancy’s facts.
