At Quality Granny Flats by GRR Build, we specialize in building high-quality granny flats in Sydney that meet all local council requirements. A granny flat is a self-contained, small home of up to 60m², typically built in the backyard of an existing house. Below are the key regulations you need to know before starting your granny flat project.
Council Requirements for Granny Flats
To be eligible for a granny flat under NSW Complying Development Certificate (CDC) Approval, your property must meet these criteria:
✔️ Minimum Land Size – Your property must be at least 450m² (different rules apply for larger blocks; see Granny Flat Setback Requirements below).
✔️ Residential Zoning – Your property must have the correct zoning (see Residential Zoning Requirements).
✔️ Minimum Width – The property must be at least 12m wide at the building line of the existing dwelling. If your property is narrower, an attached granny flat may be an option.
✔️ Setback Rules – The granny flat must maintain:
- 3m setback from the rear boundary
- 0.9m setback from side boundaries
- 3m distance from any existing trees over 4m in height
✔️ Maximum Size – The granny flat must not exceed 60m² in external area.
✔️ One Granny Flat Per Block – Only one granny flat is permitted per eligible block.
If your property does not meet the above NSW requirements for CDC Approval, our expert team at Quality Granny Flats by GRR Build can assess whether Development Application (DA) Approval through your local council is a viable alternative. Contact us today to discuss your options!
