Do You Need Planning Permission for a Garden Shed in Ireland?
You do not need planning permission for a garden shed in Ireland if it is behind the house, the TOTAL area of all garden structures stays at or under 30 sq m, it leaves at least 25 sq m of private garden, and it is under 4m high (pitched roof) or 3m (flat roof). It must not be lived in.
Rules have conditions, and the conditions are where projects fail. Answer a few questions about your exact situation and get a plain-English answer with the regulation cited.

- 1.The 30 sq m limit is CUMULATIVE -- it covers the total of all sheds, garages, and garden structures on the property, including ones a previous owner built.
- 2.The shed must be behind the front building line of the house -- a shed in the front garden needs permission.
- 3.It must not reduce your remaining private open space below 25 sq m.
- 4.Maximum height: 4m with a tiled or slated pitched roof, 3m with any other roof.
- 5.It cannot be used for living or sleeping in, keeping pigs/poultry/horses, or running a business with callers -- those uses need permission regardless of size.
- 6.Exemptions do not apply to protected structures or within an Architectural Conservation Area (ACA).

Frequently asked questions
What size shed can I build without planning permission in Ireland?
Up to 30 square metres -- but that limit covers the combined floor area of every shed, garage, and garden structure on the property, not just the new one. If existing structures already total 15 sq m, your new shed can only be 15 sq m.
Can I sleep in my garden shed?
No. The exemption specifically excludes use for human habitation. Using a shed or garden room as sleeping accommodation is a change the exemption does not cover, whatever its size.
Do I need planning permission for a shed in my front garden?
Yes. Exempt garden structures must be behind the front building line of the house. Anything forward of that line needs planning permission.
Turns out you need permission?
Start with the pre-submission checklist, estimate costs with the fee calculator, and read the step-by-step application guide. For uncertain cases, a Section 5 Declaration from your council (~€80) gives a formal ruling either way.
