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.

Fast-track available

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).

Sydney: assessed by City of Sydney under the New South Wales rules below.

Approval pathway: Three tiers. Exempt development (no approval) for small sheds that meet every standard in the Codes SEPP; a Complying Development Certificate (CDC), which is certifier sign-off rather than a DA, for larger compliant sheds; or a full DA to council if the shed fails a standard or the site is constrained by heritage, flood, bushfire or foreshore controls.

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

Overlays can change your eligibility

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.

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.
