A granny flat

1 of the 25 blocks we checked could take one. North Sydney 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 Mcmahons Point

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

Under North Sydney Local Environmental Plan 2013 a dual occupancy needs 450 m² — this LEP sets no frontage minimum, so Council's DCP governs width.

Only 2 of the 25 blocks we checked were ordinary R2 land outside the Low and Mid-Rise area, which is too few to read anything into — most of Mcmahons Point in our sample was zoned or mapped some other way.

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 Mcmahons Point 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

21 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 Mcmahons 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 Mcmahons Point. Your own block is the only one that answers for itself — that is what the box on the right is for.
