Can I build a duplex or granny flat in Haymarket?
Most of Haymarket is land this tool does not answer for. 24 of the 24 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.
Haymarket sits in City of Sydney's area under Sydney Local Environmental Plan 2012. We ran 24 real Haymarket addresses through the checker: the typical block is 312 m² with 12.6 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 24 blocks we checked could take one. 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 Haymarket
0 of the 24 blocks we checked could carry two or more separate homes today.
Sydney LEP sets no minimum lot size or frontage for a dual occupancy — permitted with consent in R2 (and R1 is an open zone), judged on the City's DCP, height and FSR maps
Low and Mid-Rise
4 of the 24 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 24 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 24 real Haymarket 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 24 blocks we checked" rather than a figure for every block in Haymarket. Your own block is the only one that answers for itself — that is what the box on the right is for.
