Historically, Rent Pressure Zones applied only to designated areas, where rent increases were generally limited to 2% or inflation, whichever was lower, subject to specific exemptions. Under the current national rent-control framework, the same broad rent-increase limit applies across Ireland, so your county does not usually determine a different cap. Special rules can apply to certain new properties, tenancy changes and rent reviews, and landlords must follow the required notice procedure. Check the latest guidance from the RTB or gov.ie, as the outcome of any dispute depends on the tenancy’s individual facts.
