There is no fixed weekly or monthly schedule for updating the RPZ list. It is updated when a designation is made, changed or ends under the relevant legislation, and the official information should then be reflected by the Residential Tenancies Board (RTB) and government sources. Because the rules and designations can change, check the RTB’s current RPZ information and map for the property’s address before relying on it. If the status is unclear, consider getting advice from a qualified tenancy adviser or solicitor.
