A granny flat
6 of the 24 blocks we checked could take one. Wollongong LEP cl 5.4(9) — the greater of 60 m² or 67% 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 Huntley
19 of the 24 blocks we checked could carry two or more separate homes today.
Wollongong LEP sets no minimum lot size or frontage for a dual occupancy — permitted with consent in R2 and judged on Council's DCP (which has its own site-area tests); the Lot Size Map governs any split into two titles
Low and Mid-Rise
None of the 24 blocks we checked fell inside the state Low and Mid-Rise area, so in this part of Huntley 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
9 of 24 were on bushfire-prone land; 1 of 24 carried a heritage listing or conservation area. 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 24 real Huntley 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 24 blocks we checked" rather than a figure for every block in Huntley. Your own block is the only one that answers for itself — that is what the box on the right is for.
