What to know about granny flat approvals before you build

Secondary dwellings can add serious value and flexibility, but approvals, access, and services need to be thought through early.

A granny flat project is more than fitting a small building in the backyard. The site needs to support access, services, setbacks, and a layout that still feels comfortable and private.

Start with the site

Access, slope, drainage, and service locations all affect how smoothly a secondary dwelling can be delivered. Even if a concept looks simple, the site conditions may shape the final layout and spend.

Think beyond compliance

A good granny flat should feel like a real home. Orientation, privacy, outdoor space, and how the dwelling relates to the main house all matter.

Site works can add more than expected

• Stormwater and plumbing routes can influence both cost and feasibility.
• Electrical upgrades and metering should be considered early.
• Retaining, access paths, and landscaping often affect the final budget more than people expect.
