Granny flat subdivision in NSW
A granny flat adds a second rental income. Subdivision turns that second dwelling into a separately titled asset. Under NSW's planning reforms, more ordinary suburban blocks than ever can do one — and increasingly both.

Why this strategy works now
Reforms opened the door
Dual occupancies are now permitted across NSW R2 zones, with state standards overriding many restrictive council rules.
Income from day one
The existing house rents while you plan; the granny flat adds a second income when complete.
Equity you create, not wait for
Subdividing or titling the second dwelling can manufacture equity rather than waiting on the market.
Buy at house prices
The right blocks still sell as ordinary homes — the development potential is priced in only after someone sees it.
Cash flow now, subdivide later
Buy an ordinary-looking house on a qualifying block, add a compliant second dwelling for income, and hold the subdivision uplift for when you're ready — or secure the approval and on-sell.
- Blocks screened for lot size, frontage, services and slope
- Council and state pathways confirmed before purchase
- Preliminary assessments available from senior town planners
- Build coordinated through to completion

Common questions
Straight answers — and a free call for the rest.
Can a granny flat be subdivided in NSW?+
In many cases the pathway is via dual occupancy and subdivision rather than subdividing a secondary dwelling itself — the distinction matters and depends on zoning, lot size and council controls. We confirm the exact pathway for a specific block before you buy it.
How much does a granny flat cost to build?+
Costs vary with size, site conditions and specification, and they change with the market — which is why we model current build quotes into every feasibility rather than quoting a generic figure here.
Will a granny flat make my property positively geared?+
Often, yes — a second rent against largely the same land cost is the most reliable way to flip a property's cash flow. The feasibility confirms it for your specific numbers.
What blocks qualify?+
As a starting point: adequate lot size and frontage for the pathway, workable slope, services in the right place, and no flood/bushfire constraints that kill the project. Our screening covers all of it.
