Generally, a property that has not been let at any time during the previous two years may qualify for an RPZ exemption, allowing the landlord to set the rent at market level rather than applying the usual RPZ increase limit. The landlord must be able to support the claim with appropriate records and comply with the required notice and RTB reporting rules. This exemption depends on the tenancy’s specific facts, so check the current guidance and rent calculator on the RTB or gov.ie before relying on it. A solicitor or qualified tenancy adviser can help if the exemption is disputed.
