Not every property in Australia is eligible for a granny flat. While many residential blocks may be suitable, local council regulations, zoning, overlays, and minimum site requirements must be met first.

Key factors that affect eligibility:

Zoning: Your property must be in a zoning that permits secondary dwellings (e.g. R2 in most states).

Minimum Lot Size: Some councils have minimum lot size requirements (e.g. 450sqm or more).

Access Requirements: Sufficient side access or rear access may be required.

Setbacks and Easements: Your property must allow for setbacks from boundaries and avoid building over easements.

Expandify conducts a Preliminary Council Assessment Report (Prelim) to determine if your site is eligible before proceeding with any build.
