Local rules
North Richmond: Redbank and the older streets
The Redbank chapter
Redbank has its own chapter in Hawkesbury’s retained Development Control Plan (DCP, council’s detailed design rules), with development precincts and separate provisions for subdivision, heritage, water and built form. It also keeps parts of the earlier keyline water landscape, so nearby open space and drainage are not just private garden.
Detached and attached
Around four in five homes were detached in the 2021 Census, and about one in five were semis or townhouses. That makes shared walls and boundaries relevant, and the figures describe the whole locality, not the current stage of any one estate.
Levels and retaining walls
Within the estate, the chapter deals with retaining walls and fences, including stepped walls and how they look from the boundary. For a pool or new yard area, approved ground levels can matter as much as the structure’s size.

What owners build here
North Richmond covers new estate lots and older, established streets. Typical jobs we certify include:
- New homes and pools on Redbank lots, to the approved platform and drainage.
- Retaining walls, fences and finished levels, designed together.
- Additions and garages on older homes, fitted to the actual yard.
- Alterations to semis and townhouses, with shared walls checked.
How approval usually works
Place your lot in the right Redbank precinct, using the current lot and subdivision papers, before relying on a standard house or shed layout. Design retaining walls with the fence and finished ground levels instead of treating each wall alone, and show existing and proposed levels for any pool terrace. With attached housing, an extension may involve shared construction, services or access, so check the title and approvals first. Many Redbank homes suit a complying development certificate (CDC, the fast-track route under state rules), but only where every state standard is met. CertifiBuild checks the estate chapter and your levels at the start.

Local questions
Questions we hear about this suburb.
No two lots in North Richmond are the same. Give us your address and we will check every map that affects it.
See the council pageIs my North Richmond home in the Redbank estate?
Redbank is a specific estate with its own chapter, so the first step is to match your address to its mapped precinct. Homes in older streets use the standard Hawkesbury controls instead. The lot documents and a planning certificate settle it.
Do retaining walls need special attention in Redbank?
Yes. The estate chapter treats retaining walls and fences as part of one arrangement, including stepped walls and their visual effect. Show existing and proposed ground levels, plus the walls, fences and neighbouring land, and get engineering and drainage advice where it applies.
I share a wall with a neighbour. Can I extend?
Maybe, but shared construction, services or access can change the answer. Check the title and approvals before assuming you control every wall or outdoor area involved. A townhouse extension is not assessed like a detached house.
