Can I build a duplex or granny flat in Croydon?
Croydon sits in Burwood Council's area under Burwood Local Environmental Plan 2012. We ran 25 real Croydon addresses through the checker: the typical block is 513 m² with 12.8 m of frontage, 11 of the 25 could add a granny flat, and 21 could carry two separate homes today.

The typical Croydon block
The middle block of the 25 we checked is 513 m² with 12.8 m of street frontage. The smallest was 138 m² and the largest 997 m². Zones in the sample: R2 (22), R1 (1), E1 (1), R3 (1).
The 25 blocks we checked, by land size.
A granny flat
11 of the 25 blocks we checked could take one. Burwood LEP cl 5.4(9) — the greater of 60 m² or 50% 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 Croydon
21 of the 25 blocks we checked could carry two or more separate homes today.
Under Burwood Local Environmental Plan 2012 a dual occupancy needs 500 m² — this LEP sets no frontage minimum, so Council's DCP governs width.
Of the 17 ordinary R2 blocks in our sample sitting outside the Low and Mid-Rise area, 10 had the 500 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
5 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
12 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 Croydon 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 Croydon. Your own block is the only one that answers for itself — that is what the box on the right is for.
