The order most people need them in

  1. 1

    Check if you need permission

    Run the exemption checker. Extensions up to 45 sq m, garden structures up to 30 sq m and rooftop solar are commonly exempt, subject to conditions.

  2. 2

    Check what the site allows

    Look up the zoning, and if the land is undeveloped and zoned for housing, check whether it is on the RZLT map.

  3. 3

    Work out the cost

    The statutory fee is €65 for a house and €34 for an extension, but professional fees and development contributions are the real budget.

  4. 4

    Get the application right

    Work through the checklist before you lodge. Applications are frequently returned as invalid over notices, scales and copies.

Frequently asked questions

Are these planning tools free?

Yes. Every tool here is free and needs no sign-up or account. They are built on the official public datasets: the Planning and Development Regulations for the exemption rules, MyPlan.ie for zoning, the local authority RZLT maps, and the national planning applications database.

Which tool should I start with?

Start with the exemption checker. Many small projects, including rear extensions up to 45 square metres, garden structures up to 30 square metres and rooftop solar, need no planning permission at all, so checking first can save months and thousands of euro. If you do need permission, the fee calculator and pre-submission checklist come next.

Is the exemption checker legal advice?

No. The tools give general guidance based on the published regulations and cite the exact class or article so you can verify the answer. Every exemption carries conditions, and none apply to protected structures or Architectural Conservation Areas. For a binding ruling, apply to your council for a Section 5 Declaration, which costs about €80 and takes 4 weeks.
