How do I know if my house is a protected structure in Ireland?

Every local authority in Ireland is required under the Planning and Development Act 2000 to maintain a Record of Protected Structures (RPS) as part of its Development Plan. The RPS lists individual buildings, structures, or groups of structures that the planning authority considers to be of special architectural, historical, archaeological, artistic, cultural, scientific, social or technical interest. If a structure is included, protection generally extends not just to the main building but to its interior, attendant grounds, and any other structures within its curtilage, such as outbuildings or boundary walls.

Most councils publish the RPS as a schedule attached to the Development Plan, often with a mapped viewer showing protected structures across the county, and many also list them on their planning or heritage pages by townland, street or unique reference number. Because entries can be added or removed as Development Plans are reviewed, it is worth checking the current adopted plan rather than an older printed copy, and confirming directly with the planning authority's conservation officer if there is any ambiguity about your specific property.

If your house does not appear on the RPS, it can still be located within an Architectural Conservation Area (ACA), which imposes a different but related set of controls, or it may simply be an older building with no formal protection at all. Because the consequences of missing a protection are significant, including possible enforcement action for unauthorised works, it is sensible to check the RPS, the ACA maps, and speak to the council before carrying out any works to an older property.
