The short answer
For most homes a garden shed is permitted development and needs no planning permission, provided it meets the outbuilding rules: it must be single storey; sit no higher than 2.5m at the eaves where it is within 2m of a boundary (otherwise up to 4m for a dual-pitched roof or 3m for any other roof); cover no more than half the garden with all buildings combined; and not stand forward of the principal elevation of the house. It must not be used as living or overnight accommodation. The main exceptions are listed buildings, conservation areas, national parks and AONBs, where stricter limits apply and you should check with your local planning authority first.
The usual answer is reassuring: a normal garden shed does not need planning permission. The rules below are the conditions that keep it that way — and the situations where you should check before you build.
The rules in brief
- Permission (usual)none — permitted development
- Single storeyrequired
- Within 2m of boundarymax 2.5m eaves height
- Garden coverageunder 50% with all buildings
- Positionnot forward of the house
The permitted-development rules
A shed normally falls under permitted development, so no application is needed if it stays inside these limits. It must be single storey. Where the shed is within 2 metres of a boundary, the maximum height is 2.5m — the limit most people hit, because sheds usually go against a fence. Further from a boundary the overall limit is up to 4m for a dual-pitched roof or 3m otherwise, with eaves still capped at 2.5m. With all outbuildings combined, no more than half the land around the original house may be covered, and the shed must not be forward of the principal elevation. It also must not be used as self-contained living or overnight accommodation.
| Condition | Permitted-development limit |
|---|---|
| Storeys | single storey only |
| Eaves within 2m of boundary | 2.5m maximum |
| Overall height (further out) | 4m dual-pitch / 3m other roof |
| Garden coverage | under 50% with all buildings |
| Position | not forward of principal elevation |

When the rules are stricter
The exceptions are the part worth checking. On a listed building, an outbuilding usually needs listed building consent. In a conservation area, national park or AONB, permitted-development rights are tighter — the footprint you can build without permission can be much smaller, and outbuildings to the side of the house may need an application. If your shed will be large, tall, close to a boundary, or your property sits in one of these designated areas, check with your local planning authority before you build rather than after.

Frequently asked questions
Do I need planning permission for a shed in the UK?
For most homes, no — a shed is permitted development if it is single storey, no higher than 2.5m at the eaves within 2m of a boundary, covers under half the garden with all buildings combined, and is not forward of the house. Listed buildings, conservation areas, national parks and AONBs have stricter rules — check with your local planning authority.
How tall can a shed be without planning permission?
Within 2 metres of a boundary the maximum is 2.5m. Further from a boundary the overall limit is up to 4m for a dual-pitched roof or 3m for any other roof, with eaves still capped at 2.5m. It must remain single storey.
Does a shed near a boundary need permission?
Not usually, provided it is no higher than 2.5m where it sits within 2 metres of the boundary and meets the other outbuilding rules. The 2.5m limit is the one most people encounter because sheds are commonly placed against a fence.
