Can I build a duplex or granny flat in Beverly Hills?

A granny flat

20 of the 25 blocks we checked could take one. Georges River LEP cl 5.4(9) — the greater of 60 m² or 10% 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 Beverly Hills

5 of the 25 blocks we checked could carry two or more separate homes today.

Under Georges River Local Environmental Plan 2021 a dual occupancy needs 650 m² and 15 m of frontage.

Of the 13 ordinary R2 blocks in our sample sitting outside the Low and Mid-Rise area — where that minimum is the only test that applies — 6 had the frontage and 3 had the land. 3 had both.

So in Beverly Hills it is the area that stops a second home more often than the frontage. A block short on land cannot be stretched, but two neighbouring blocks together clear it easily — which is why duplex sites here tend to be assembled in pairs rather than found.

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 Beverly Hills 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

None of the blocks we checked came back bushfire-prone, flood-mapped or heritage-listed. 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 Beverly Hills 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 Beverly Hills. Your own block is the only one that answers for itself — that is what the box on the right is for.
