South West Sydney
Private building certifier in the Campbelltown City Council area
CertifiBuild certifies house alterations, granny flats and outbuildings across Campbelltown. Mine subsidence is the local issue that catches most owners by surprise. In some parts of the city, work may also need separate sign-off from Subsidence Advisory NSW.

Local rules
What shapes approvals here.
Mine subsidence approvals
Part of Campbelltown, mainly in the south, sits in a proclaimed mine subsidence district. Subsidence is ground movement caused by old or current mining below. Inside a district, building work must be approved by Subsidence Advisory NSW. That agency is separate and runs its own process. Its approval is in addition to your development approval, not a condition of it.
What your guideline means
Each property within a district has a guideline assigned to it. The guideline decides who can approve your work. For some guidelines, a compliant design can be signed off by council or a registered certifier. For others, only Subsidence Advisory NSW can decide. Work that needs a merit assessment by the agency takes considerably longer. Even a simple extension on a normal suburban block can be caught. Checking the district map is our first step.
Local plans
The Campbelltown Local Environmental Plan 2015 (LEP) applies across the council area. The detailed design rules are in the Campbelltown (Sustainable City) Development Control Plan 2015. Renewal precincts in Greater Macarthur's growth area are managed by the state, under separate controls.
Older homes and rural lots
Many homes in Woodbine went up in the late 70s and the 80s. They often suit extending or adding a second storey, provided the existing structure can take the load. Up on the Wedderburn plateau, three things decide where a rural home can go. These are bushfire exposure, room for on-site effluent and distance from watercourses. Bushfire prone land appears in 33 of the 34 suburbs.
Send us your survey, plans and council planning certificate. We will check subsidence and bushfire status before you design.
Local know-how
Local know-how for four Campbelltown suburbs
Glenfield
Most of Glenfield dates from the 1950s and 60s. Owners extend at the back or upstairs, knock down and rebuild, or add a granny flat. Around the station, though, land was rezoned by the state in July 2021. East of the station, a separate DCP part now sets the detailed rules. A proposal to rezone Glenfield West is still being assessed. Until it is decided, design to the current rules, not the proposed ones.
Rosemeadow
Parts of Rosemeadow were laid out in the Radburn style. Homes face a shared walkway and back onto the road. So the apparent front may not be the legal frontage. Setbacks are measured from that frontage. We resolve this using the survey together with the deposited plan, which is the official subdivision plan. Many homes are now about fifty years old. Older garage conversions or enclosed carports may never have been approved, which must be fixed before any new work is certified.
Ingleburn
Close to one in three homes in Ingleburn are townhouses, terraces or semis. For those owners, the title comes first. A patio or addition may need the owners corporation to agree. Fire separation also comes into play when work is close to a shared wall. In the town centre, a dedicated DCP part sets large minimum site sizes for unit blocks. Those numbers are not used for a normal house lot anywhere else in the suburb.
Kentlyn
Kentlyn is a small bushland plateau of big lots overlooking the Georges River gorge. New homes, big sheds and additions are typical. The asset protection zone, the cleared buffer around a home in bushfire areas, must be contained inside your own boundary. Where there is no sewer, a site wastewater report sets buffers to creeks and bores. Bull Cave, an Aboriginal place in Darling Avenue, is on the State Heritage register. Digging work may need a separate Aboriginal heritage check or permit.
Why Campbelltown owners and builders bring projects to CertifiBuild
We understand how Campbelltown's precinct plans, renewal rules and rural controls play out on real blocks. At the start, we check your lot against the maps that apply and confirm the frontage, title type and pathway. When you have a question, we get back to you promptly. Inspections are booked to suit your builder's program, not the other way around. We stick to Class 1 homes and granny flats, plus pools, sheds and other Class 10 structures.

Local questions
Questions we hear in this area.
No two lots are alike. Share your address and we will review the maps that cover it.
All council areasHow can I tell if my lot is in a mine subsidence district?
Ask for the district map to be checked against your address first. Part of Campbelltown, mostly in the south, lies in a proclaimed mine subsidence district, and even an ordinary suburban extension can be caught. If yours is inside, the property’s own guideline shows who may approve the work: council or a registered certifier for some, or Subsidence Advisory NSW alone for others. That agency’s sign-off comes on top of your development approval. Send us your address and planning certificate, and we will look it up at the outset.
Could my home in Woodbine support a second storey?
Often, yes. Plenty of Woodbine houses went up in the late 70s and the 80s, and they tend to suit extensions or an added second storey. The catch is whether the existing footings and frame can carry the extra load. We suggest a structural engineer inspects the house before you lock in plans, since the original drawings may not show what was actually built. Also find out if the property lies in a mine subsidence district, as that adds a separate approval. Once you know both, we can map out your approval route.
What affects where I can build on a Wedderburn rural lot?
Three things decide where a new home can sit on a Wedderburn rural lot: bushfire exposure, room for on-site effluent disposal, and the distance from creeks and other watercourses. On the plateau these often pull in different directions, so the house site is a balance between them. A bushfire attack level (BAL) assessment sets the building standard, and with bushfire prone land showing up in all but one Campbelltown suburb, it is part of most jobs. Have a wastewater report and BAL assessment done early, then we can help test possible house positions.
