Local rules
Picton: eight heritage precincts and a creek town
A town divided by creek, rail and hills
Council's centre study notes that the creek (Stonequarry Creek), the railway, main roads and surrounding hills break Picton into pieces. At the 2021 Census, 90.1% of occupied homes were detached houses, 4.8% attached and 3.8% flats. Wollondilly's DCP (council's detailed design rules) divides the heritage area into eight precincts, covering the commercial main street, the creek and rail corridor, and several distinct groups of homes.
Abbotsford and release areas
A separate DCP section covers mapped land at Abbotsford Road, a former pastoral property. It controls views, architectural form and how new homes and outbuildings interpret the old estate. There are also urban release provisions covering Picton, Tahmoor and Thirlmere more broadly. So a heritage cottage, an Abbotsford lot and a new release lot can each follow different detailed controls.
Mine subsidence
Comparing official maps, mine subsidence districts cover about 65.4% of the locality's Wollondilly land: Wilton about 31.3%, Bargo about 19.1% and Picton about 15.0%. Those are land shares, not counts of homes, and some land sits outside all three.
Typical work
Common projects and how they get approved
What owners build here
Since most homes are detached, house work is the main game. Typical Class 1 and 10 jobs include:
- Rear additions to cottages, shaped to the building group in your heritage precinct.
- Replacement homes and infill dwellings where zoning and lot conditions allow.
- Garages and sheds, including on Abbotsford land where roof form and pitch are controlled.
- Pools, assessed for heritage and site constraints rather than assumed exempt from them.
- Alterations to existing semis and townhouses, checking shared walls first.
Flats exist in town, but apartment work is outside Class 1 and 10, so another certifier is needed for that.
How approval usually works
Find your lot on the heritage map now in force, and note its precinct, before designing. Complying development carries its own heritage limits and exceptions. Conservation status alone will not tell you if you can use it. A CDC is a code-based approval set by State rules. On mapped Abbotsford land, homes and outbuildings need a roof pitch of 30 to 40 degrees with gables, and should read as single storey with upper rooms inside the roof. An off-the-shelf shed with a shallow roof may need rethinking. Check whether a subsidence district covers the lot and, if so, which guideline applies. Where flood controls apply, get property-level flood information. CertifiBuild maps precinct, Abbotsford, subsidence and flood questions together, so the right controls guide your design from day one.

Local questions
Questions we hear about this suburb.
No two lots in Picton are the same. Give us your address and we will check every map that affects it.
See the council pageWill a second storey work on my Picton heritage home?
It depends on your heritage precinct, the controls mapped over your lot and how the new rooms sit against the house and next door. Wollondilly’s development control plan (DCP) divides Picton’s heritage area into eight precincts that each have a distinct feel. On the mapped Abbotsford Road estate, homes should look single storey, with any upper rooms tucked inside the roof. Elsewhere, the heritage or housing controls that fit your lot apply. Find your precinct on the heritage map before sketching.
Can I put a standard kit shed on Abbotsford land?
Maybe not. On mapped Abbotsford land, a former pastoral property, sheds and other outbuildings face the same roof controls as homes: a pitch of 30 to 40 degrees with gables. Many off-the-shelf kits have a much shallower roof, so they may need rethinking. Landscape and view controls also apply. Read the map showing where these rules apply, plus the full requirements, before you buy a kit or settle on a position. These rules apply only to that mapped land.
Which mine subsidence district covers my Picton home?
It could be Wilton, Bargo, Picton or none. Comparing official maps, subsidence districts take in about 65.4% of Picton’s land in Wollondilly, with Wilton taking roughly 31.3%, Bargo 19.1% and Picton 15.0%. Those are land shares, not home counts, and some land sits outside all three. Look up your lot on the official district map to find the guideline that applies. Do not assume the Picton district covers you because of the town name.
