Granny flats in Randwick — common questions
Can I build a granny flat in Randwick?
It depends heavily on your specific address. Randwick has 574 heritage items and many streets in Coogee, Kensington, and Randwick itself are in heritage conservation areas. Lot sizes in inner Randwick are often below 450 m². Check your address above.
Why are many Randwick properties ineligible for a granny flat?
Two main reasons: lot size (many terrace and semi-detached lots are under 450 m²) and heritage (conservation areas cover large parts of Randwick, Coogee, and Kingsford). The checker identifies which constraint applies to your address.
What lot size is needed for a granny flat in Randwick?
The minimum is 450 m². Detached houses in outer Randwick suburbs like Matraville and Little Bay are more likely to clear 450 m². Inner suburbs and terrace streets typically do not.
Do acid sulfate soils affect granny flat eligibility in Randwick?
Parts of coastal Randwick have acid sulfate soil mapping. The checker above cross-references Class 1 and 2 acid sulfate soil maps — properties on these are excluded from SEPP Housing 2021 complying development.
Do I need council approval for a granny flat in Randwick?
If all SEPP checks pass, a CDC through a private certifier is sufficient. Randwick City Council is involved only if a criterion fails.
