Private building certifier in the Canterbury-Bankstown Council area
CertifiBuild certifies knockdown rebuilds, granny flats, garages and pools across Canterbury-Bankstown. Near Bankstown Airport, the big local issue is protected airspace. A tall structure, or even a crane, may need federal approval on top of your planning approval.

Local rules
What shapes approvals here.
Height limits near the airport
Bankstown Airport sits inside this council area. The airspace around it is protected by Commonwealth rules, not council rules. A height ceiling extends over a broad area and rises further from the runways. If a structure breaks through it, you need a separate federal airspace approval. That applies to temporary items too, such as a tower crane. Most single houses sit well below the ceiling, but it is worth checking early.
Aircraft noise and flooding
The local environmental plan (LEP) includes rules for building in aircraft noise areas. Flooding is the other main hazard. Floodplain controls come from the Cooks River, the Georges River and Prospect Creek. Your planning certificate will say if the lot is a flood control lot. Some suburbs also include bushfire prone land.
One set of local rules
Canterbury-Bankstown LEP 2023 replaced the old Bankstown and Canterbury plans. A single 2023 development control plan (DCP) now holds the detailed design rules. That makes the starting point simpler than in many merged councils. So the question is rarely which plan applies. Instead, it comes down to the airspace, noise and flood maps for your address.
CDC or DA?
A complying development certificate (CDC) is a code-based approval a private certifier can issue. A flood affectation alone does not exclude one. The design must then meet the code's flood standards. Where it cannot, a development application (DA) goes to council. Typical projects here include rebuilds in Yagoona, dual occupancies in Padstow and granny flats in Earlwood. To start, send through your survey, plans and planning certificate and we will review the airspace, noise and flood maps.
Local know-how
Canterbury-Bankstown suburbs: local detail that changes a design
Earlwood
About eight in ten homes in Earlwood are separate houses. Typical work is second storeys, rear living additions, rebuilds and garages. Some designs add a lower garage level. The residential chapter controls how far a basement can stick out, plus retaining walls and cut and fill. So survey the levels first, because a lower floor hidden on plan can show in elevation. The Undercliffe Bridge precinct beside the Cooks River sets its own stepped height and view rules. Those rules only apply within that precinct.
Padstow Heights
Padstow Heights is mainly houses, with a small shopping strip on Dilke Road. The residential rules discourage big changes to natural ground just to make a flat building pad. Designs that follow the slope often keep more of the garden. Little Salt Pan Reserve serves as a bushcare site run locally. Being close to it does not by default make a lot bushfire prone. We look up the map for your address.
Picnic Point
Picnic Point combines houses with a fair number of semis and townhouses, close to the river at Lambeth Reserve. Pools, decks, garages and extensions are common, often combined in one project. The residential chapter maps a Foreshore Protection Area. Where your lot is within it, the DCP guides materials and landscaping. Colours and planting should then be shown in the first drawings. Check whether the whole package can go as a CDC, rather than assuming it.
Campsie
Most Campsie homes are apartments, but houses and townhouses still see extensions, garages and granny flats. Council endorsed a town centre planning proposal in May 2026 and sent it to the state in June. The existing controls apply until it begins. Proposed heights in the master plan are not yet usable for any lot.
Why Canterbury-Bankstown owners and builders use CertifiBuild
We have hands-on exposure to this council's DCP chapters, from sloping streets to foreshore and centre maps. Our first step is checking the maps, levels and title that affect your lot. We keep you updated quickly when questions come up and book inspections to fit the build program. Because our practice covers only Class 1 homes and Class 10 structures, we stay focused on residential projects.

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 areasDoes a crane on my building site need airport approval?
It can. Bankstown Airport’s protected airspace is governed by Commonwealth rules, and they apply to temporary structures such as tower cranes, not only finished buildings. If a crane would break through the height ceiling, a separate federal airspace approval is needed on top of your planning approval. The ceiling covers a wide area and rises further from the runways. Most single house sites never use a tower crane, but larger rebuilds should check. We raise crane height at the start, so it is sorted before the crane hire is booked.
Which creeks and rivers cause flooding in Canterbury-Bankstown?
Three waterways carry floodplain controls in Canterbury-Bankstown: the Cooks River, the Georges River and Prospect Creek. Lots near any of them can be flood control lots, and your planning certificate confirms whether yours is. Flood affectation alone does not exclude a complying development certificate (CDC), but the design then has to pass the flood rules in the code. Where it cannot, a development application (DA) goes to council. Read the planning certificate before choosing floor levels, and we can review the flood map together with the airspace and aircraft noise maps.
Do the old Bankstown and Canterbury plans still apply?
No. The old Bankstown plan and the old Canterbury plan were replaced by the Canterbury-Bankstown Local Environmental Plan (LEP) 2023 and a single 2023 development control plan (DCP), which now apply everywhere across Canterbury-Bankstown. That makes the starting point simpler than in many merged councils, where older plans linger. For a rebuild in Yagoona or a granny flat in Earlwood, the real questions are usually the maps for airspace height, aircraft noise and flooding. A separate Campsie town centre proposal is under way, but existing controls apply until it begins.
