What should I check before buying a house in Ireland?

Before buying a house in Ireland you should check its planning history and compliance, title and folio, structural condition via a survey, and services such as water, drainage and boundaries. Your solicitor will also run pre-contract searches, but buyers should independently verify planning status for any extensions or alterations.

Buying a house involves more than agreeing a price and signing contracts. A prudent buyer checks the legal title (registered or unregistered, and whether the folio map matches the physical boundaries), the planning history of the house and any extensions, sheds or conversions, and whether a Certificate of Compliance with planning and Building Control was issued where required. Unauthorised works can affect mortgage approval, resale value, and in some cases expose a buyer to enforcement risk after purchase, so it's worth raising these questions before you commit to a contract.

A structural survey by a qualified engineer or surveyor should identify defects, dampness, roof condition, and any signs of subsidence or unauthorised structural alteration. Alongside this, check services: is the property on public water and sewerage from Uisce Éireann, or does it rely on a private well and septic tank that should be tested and maintained? Ask about BER rating, which is a legal requirement for most sales, and whether any statutory notices, compulsory purchase orders, or protected structure listings apply.

Your solicitor will conduct pre-contract searches covering judgments, planning, and outstanding charges on the folio, but these searches are legal rather than physical checks. It remains good practice for a buyer to independently review the planning register entry for the property with the local authority and, where a planning history is unclear, to request a planning search report before signing contracts.

Key checks before buying a house

Cover these areas before signing contracts:

  • Title and folio: confirm registered ownership and boundaries match the property
  • Planning history: check permissions for the house, extensions, and outbuildings
  • Building Control compliance: look for Certificates of Compliance on notified works
  • Structural survey: engage a qualified surveyor or engineer
  • Services: water supply, drainage, septic tank condition, and BER rating
  • Local authority searches: outstanding notices, protected structure status, or road proposals
  • Boundaries: verify fences, walls and rights of way match title documents

Why planning history matters

Unauthorised extensions or alterations can complicate a sale, delay mortgage drawdown, or require retrospective planning permission or a certificate of exemption before the transaction can close. Checking planning status early gives time to resolve issues before you're contractually committed.
