A granny flat
14 of the 25 blocks we checked could take one. Woollahra 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 Darling Point
25 of the 25 blocks we checked could carry two or more separate homes today.
Woollahra LEP sets no minimum lot size or frontage for a dual occupancy — permitted with consent in R2 and judged on Council's DCP; the two homes cannot be put on separate Torrens titles (cl 6.5) — strata only
Low and Mid-Rise
9 of the 25 blocks sat inside the state Low and Mid-Rise area — within about an 800 m walk of a listed centre or station. Inside it the Housing SEPP overrides the LEP minimums: a dual occupancy on 450 m² with a 12 m frontage, terraces on 500 m² / 18 m, townhouses on 600 m² / 12 m and a manor house on 500 m² / 12 m, up to 9.5 m. That is what lifts the two-homes figure above; a block one street outside the line gets the LEP figure instead.
What else turned up
10 of 25 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 25 real Darling Point 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 Darling Point. Your own block is the only one that answers for itself — that is what the box on the right is for.
