A granny flat

21 of the 24 blocks we checked could take one. Central Coast LEP cl 5.4(9) — the greater of 60 m² or 30% 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 Wamberal

18 of the 24 blocks we checked could carry two or more separate homes today.

Under Central Coast Local Environmental Plan 2022 a dual occupancy needs 550 m² — this LEP sets no frontage minimum, so Council's DCP governs width.

Of the 22 ordinary R2 blocks in our sample sitting outside the Low and Mid-Rise area, 17 had the 550 m². There is no LEP frontage test to pass here, but Council's DCP still judges width, setbacks and private open space, so clearing the area alone does not settle it.

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 Wamberal 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

3 of 24 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 24 real Wamberal 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 Wamberal. Your own block is the only one that answers for itself — that is what the box on the right is for.
