Use the Residential Tenancies Board’s official Rent Pressure Zone map or list of designated areas and search for the property’s local authority or location. Check the result against the property’s exact address, as boundaries can differ within an area and designations may change. Whether RPZ rent rules apply can also depend on the tenancy date and the current legislation, so read the RTB’s latest guidance before relying on the result. If the position is unclear, consider asking a solicitor or the RTB for guidance.
