A granny flat
14 of the 25 blocks we checked could take one. Bayside LEP cl 5.4(9) — the greater of 60 m² or 20% 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 Bexley North
25 of the 25 blocks we checked could carry two or more separate homes today.
Bayside LEP sets no minimum lot size or frontage for a dual occupancy — permitted with consent in R2 and judged on Council's DCP; a split into two titles needs 350 m² per lot with one home on each (cl 4.1(3B)), the access handle of a battle-axe not counted
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 Bexley North 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 Bexley North 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 Bexley North. Your own block is the only one that answers for itself — that is what the box on the right is for.
