How do I search planning applications in Co. Monaghan?

Two ways. The national planning applications map (nationalplanningapplications.ie) carries every council's register on one map: search the address, then look at the streets around it. The planning authority for the towns on this page is Monaghan County Council; each also runs its own online planning search with the full file, drawings and decision. For a house you are buying, the 300 m around it matters more than the town count.

Which towns in Co. Monaghan have the most planning activity?

By applications within 2 km of the town centre in the last three years: Carrickmacross (111), Castleblayney (84). Counts include extensions, one-off houses and changes of use, not only housing schemes.

Does planning permission nearby change what a house is worth?

A granted permission for a large scheme behind the house can take light, a view or parking, and it means construction traffic for two years. It can also add a school or a shop. Read the description, the decision and the appeal status before you bid. The report lists every application within 300 m of the Eircode with that detail, and checks the house's own planning and building-control file.
