Local rules
Blackbutt: hillside lots, townhouses and a cottage park
Heritage beyond the house
Blackbutt Forest Reserve and Wentworth Cottage Park give the suburb its own heritage emphasis. Section 28.6 of Shellharbour’s Development Control Plan (DCP, council’s detailed design rules) covers significant trees, archaeology and cultural landscape. What matters is where a structure, driveway or excavation sits in relation to a protected feature, not just the age of the house.
A real share of attached homes
Around seven in ten homes were detached in the 2021 Census, and nearly three in ten were townhouses or duplexes. A courtyard roof or a moved wall in an attached home can involve shared walls, so the original approval and subdivision plan come first.
Special building lines
The DCP sets particular rear building lines for named sites in Springdale Close and Dunsters Lane, to suit the landform and views from transport routes. They are not a blanket rule for Blackbutt.

What owners build here
Blackbutt’s mix of detached and attached homes leads to varied jobs. Typical work we certify includes:
- Rear additions on hillside lots, with levels and excavation checked.
- Pools and garages, away from protected trees and archaeology.
- Courtyard roofs and alterations to townhouses and duplexes.
- Decks, patios and fences.
How approval usually works
Work out whether your lot is one of the named sites with a special building line, then plot the line on the survey instead of borrowing a neighbour’s. Near the cottage park, show excavation, levels and landscape treatment as well as the finished walls. An attached home needs a clear boundary between private and shared work, so check the subdivision plan for common property, shared structure or fire separation. A complying development certificate (CDC, the fast-track route under state rules) addresses state standards only and does not replace owners’ consent. CertifiBuild plots the lines and heritage relationship on your survey early.

Local questions
Questions we hear about this suburb.
No two lots in Blackbutt are the same. Give us your address and we will check every map that affects it.
See the council pageDoes the special rear building line apply to my Blackbutt lot?
Only if your lot is one of the specific sites listed for Springdale Close or Dunsters Lane. It is not a blanket setback for the suburb. Check whether your lot is described, plot the correct line on the survey, and do not apply it to a neighbour because the outlook looks similar.
Do I need heritage checks near Wentworth Cottage Park?
Often, if the work is close to the park. The controls protect the cottage park’s cultural landscape, archaeology, historic trees and views. They do not mean every private garden has archaeology or protected trees, so confirm the actual relationship before choosing a standard pool or garage.
Can I roof my townhouse courtyard?
Maybe, but start with the subdivision plan and the original approval. Find out whether the roof touches common property, a shared structure or fire separation, because that affects who must agree and how the work is documented.
