Can I build a duplex or granny flat in East Kurrajong?
Most of East Kurrajong is land this tool does not answer for. 25 of the 25 blocks we checked sit in rural, conservation, industrial or special-purpose zones rather than a residential one, and Block Checker covers residential zones only. The counts below are what it could assess — they are not a finding that nothing can be built. For land like this, a planner reads the LEP for the zone directly.
East Kurrajong sits in Hawkesbury City Council's area under Hawkesbury Local Environmental Plan 2012. We ran 25 real East Kurrajong addresses through the checker: the typical block is 38,762 m² with 109.8 m of frontage. Most of them are not residential land, so see the note below before reading the counts.

A granny flat
0 of the 25 blocks we checked could take one. Hawkesbury 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 East Kurrajong
0 of the 25 blocks we checked could carry two or more separate homes today.
dual occupancies are not in the R2 land-use table of the Hawkesbury LEP, so outside the state Low and Mid-Rise catchment they are not permitted; inside it the state 450 m² / 12 m rule applies
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 East Kurrajong 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
25 of 25 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 25 real East Kurrajong 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 East Kurrajong. Your own block is the only one that answers for itself — that is what the box on the right is for.
