Sheds & Garages rules in Sydney
Building a shed or garage in Sydney? City of Sydney applies the New South Wales planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Often no approval needed within the exempt limits
A detached shed or garage can be built with no council approval as 'exempt development' if it stays within the size, height and setback limits in the Codes SEPP. Go over them and you'll need a fast-track Complying Development Certificate (CDC) or a full development application (DA).
Key rules at a glance
| Max floor area (no approval) | 20 m² in residential and most zones; 50 m² in rural zones (RU1–RU4, RU6, R5) |
| Max height | 3 m to top of roof (up to 4 m if under a 30° plane projected from 3 m at the boundary) |
| Setback from boundary | ≥900 mm in residential zones; ≥5 m from every boundary in rural zones |
| Position on lot | Behind the building line to any road frontage (non-rural zones) |
| Construction | Detached, single storey, non-habitable; metal cladding of low-reflective material |
| Larger or non-complying sheds | Go through a CDC or a DA |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
How often this applies in Sydney
These are the overlays that can remove the fast-track, measured across every parcel in Sydney from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | 82.12% | 24,621 parcels flagged. The rest are mapped and sit outside it. |
| Flood | Not mapped | No flood mapping is published for Sydney, so it cannot be ruled out here. That is not the same as the land being clear. |
| Bushfire | 0% | Mapped right across Sydney, and no parcel is flagged. |
The most common zone in Sydney is General Residential, covering 58.8% of its 29,981 parcels. What you can build is decided by your own lot's zone, not the council's most common one.

Frequently asked questions
Do I need council approval for a shed or garage in Sydney?
Often not. New South Wales allows a shed or garage to proceed without a full development application when it meets the standards, and City of Sydney follows that framework. But local overlays — heritage, flood or bushfire — can remove the fast-track, so check your exact address before you rely on it.
Which council approves a shed or garage in Sydney?
City of Sydney is the consent authority for Sydney (Inner Sydney). You can review local planning controls on the council website and lodge through your state planning portal.
How big a shed can I build in NSW without council approval?
Up to 20 m² floor area in residential and most other zones, or up to 50 m² in rural zones (RU1–RU4, RU6, R5), provided it's no higher than 3 m, behind the building line and meets the boundary setbacks. Anything larger needs a CDC or DA.
