A granny flat
20 of the 25 blocks we checked could take one. Blacktown LEP cl 5.4(9) — the greater of 60 m² or 5% of the house’s total floor area, parking excluded. Separately, the state Housing SEPP allows a granny flat of up to 60 m² through the ten-day complying-development route on a lot of 450 m² or more with a 12 m frontage, where the land is not flood, bushfire or heritage constrained.
Dual occupancy (duplex) rules in The Ponds
13 of the 25 blocks we checked could carry two or more separate homes today.
Under Blacktown Local Environmental Plan 2015 a dual occupancy needs 500 m² — this LEP sets no frontage minimum, so Council's DCP governs width.
Low and Mid-Rise
None of the 25 blocks we checked fell inside the state Low and Mid-Rise area, so in this part of The Ponds the LEP minimums are what count. The boundary is a walking distance from a listed centre, so it can cut through a suburb — the checker reads which side of it your own address sits on.
What else turned up
2 of 25 were on bushfire-prone land. Any of those takes a block out of the fast-track routes and into a full DA, so it changes the answer more than the lot size does.
How we got these numbers
We took 25 real The Ponds street addresses from the NSW geocoder and ran every one through the same engine this site runs for you, reading the planning controls live. Nothing here is modelled or estimated.
It is a sample, not a census. The addresses are a spread across what the geocoder returns, so treat these as "of the 25 blocks we checked" rather than a figure for every block in The Ponds. Your own block is the only one that answers for itself — that is what the box on the right is for.
