A count for the whole town says how busy the planning office is. What matters for a purchase is the 300 m around the house: the field behind it, the corner site, the neighbour’s attic conversion. That is what the report lists, with the decision and the appeal status for each file.
What to check before you bid
Three things. First, permissions granted but not yet built near the house: the register shows them, the street does not. Second, whether the house itself has a planning file: an extension without permission is a title problem your solicitor has to fix before closing. Third, the zoning in the development plan for the fields around it. The report covers all three for one Eircode.

Enter the Eircode. The free snapshot shows which of the twenty-nine checks flag up. The full report (€24.99, one house, no account) lists every planning application within 300 m of the house with status, decision and appeal, checks the property's own planning and building-control file, and shows the zoning of the land around it.

Questions people ask
- How do I check planning applications near a house in Castleknock?
- The national planning register (nationalplanningapplications.ie) maps every application since about 2010. Search the address, then look at the streets around it, not only the plot. Applications within 300 m are the ones that change your view, your light and your parking. The report lists them for the exact Eircode with status and decision.
- Is a lot being built in Castleknock?
- 542 applications were lodged within 2 km of the town centre in the last three years, 2 of them for ten or more homes (24 units in total). A modest pipeline, mostly one-off houses and extensions.
- Does a planning application nearby affect the price?
- A granted permission for a large scheme next door can cut what a house is worth and can also mean two years of noise. It can also raise prices if it brings a school or a shop. Read the description, the decision and the appeal status. The report gives you that for everything within 300 m.
