Granny Flat Lane Cove — frequently asked questions

What's the cheapest way to build a granny flat in Lane Cove?

The CDC pathway under SEPP (Affordable Rental Housing) is the fastest and cheapest approval route — typically 10–15 business days vs 8–14 weeks for a full DA. Buildana designs to maximise the 60m² SEPP allowance while meeting setback, private open space and landscaped-area controls.

What rental yield can I expect from a Lane Cove granny flat?

Rental yields vary by suburb within Lane Cove — premium pockets (water-proximate, heritage-fringe, hospital staff demand) command higher rents than inland suburban. Buildana provides realistic suburb-specific rent ranges sourced from current Lane Cove comparables.

Does my Lane Cove block need to meet a minimum size?

SEPP requires 450m² minimum for a 60m² granny flat under CDC pathway, with compliant front, side and rear setbacks. Buildana confirms suitability at proposal stage with a free site assessment.
