CDC, Construction Certificates, inspections and Occupation Certificates — for homeowners, builders, architects and developers across Sydney, the Central Coast, Newcastle and Wollongong.
Or call (02) 8772 4022 — we are happy to talk a project through.
Professional certification. Clear communication. Reliable service.
Six things that decide whether a certification runs smoothly — and what we do about each of them.
A Complying Development Certificate within 15 days of the lodgement date. A Construction Certificate promptly once all required documentation is complete. Figures you can plan a construction program around.
Requirements in plain language, and a straight answer on what is still outstanding. You deal with us, not a queue.
Registered to certify residential building work in New South Wales, from a single granny flat through to multi dwelling housing.
You get the full list of what is needed at the start, not one document at a time while the clock runs.
Outstanding documents, inspection bookings, reports and certificates in one place, day or night.
You book each critical stage inspection as the work reaches it and we confirm the time. The report and site photographs go straight back into your project file.
From the first approval to the certificate that lets the building be occupied. We can carry a project the whole way, or pick one up from another certifier.
A combined planning and building approval in one certificate, determined without a development application to council where the project meets the standards.

Five steps, in the order they actually happen. Nothing can be skipped — which is why it helps to know the order before you start.
The address, the type of work and whatever plans exist. We come back with a fixed fee.
Title, survey, plans and engineering. We list what is missing rather than letting the clock run.
Once the file is complete we assess it and issue your CDC or Construction Certificate.
Critical stage inspections as the work reaches each point. You book them, we confirm the time.
Final inspection passed and every certificate received, we issue the OC and the building can be occupied.
We work with you throughout to keep your project moving, and every outstanding document sits in your portal as a live list.
Clear guidance through the certification process for new homes, renovations, extensions and other residential projects.
Responsive certification support designed to help builders keep projects progressing.
Practical certification advice to help identify compliance requirements early, while the design can still absorb them.
Professional certification support for residential and development projects.
A reliable certification partner for documentation, approvals and project delivery.
How we work with the trade: problems raised at drawing stage, one contact who answers, and every project in one portal.
For builders and designers →Residential development of every kind. Not listed? Call us — a short conversation is usually enough.
Where the lot and the design meet the standards, a private certifier can determine the approval without going to council. The site decides, and the title is usually where it is decided.
We will tell you honestly whether the pathway looks open before you commit to drawings. No assessment can be guaranteed in advance.
Check CDC eligibilityHave these ready and the assessment moves quickly. Almost every delay in certification is a missing document rather than a slow assessment.
For a Construction Certificate we also need the development consent council issued and the conditions attached to it.

A private certifier is a professional registered to assess and certify building work against the relevant legislation and the Building Code of Australia. A certifier has to be appointed for building work, and it is the owner who makes that appointment.
A Complying Development Certificate is a combined planning and building approval in one document. It applies where the work meets the fixed standards set out in the State planning policy for complying development. Because those standards are fixed, the proposal is measured against them rather than judged on merit — which is why a private certifier can determine it without a development application to council.
Where council has already granted development consent, the Construction Certificate is the second half of the approval. It confirms the construction drawings and specifications satisfy the Building Code of Australia and the conditions council attached to that consent. It has to be issued before building work begins.
Before building work starts. The Principal Certifier is appointed by the owner, carries out the critical stage inspections during construction, and decides at the end whether an Occupation Certificate can be issued. You do not have to appoint the certifier who issued your approval.
Inspections are mandatory at set points in the build, and they have to happen before the next stage covers the previous one. For a typical residential project that means the footings before the pour, the reinforcement in place, the frame once it is up, wet area waterproofing before tiling, stormwater drainage, a pool barrier where there is one, and the final inspection. The exact schedule depends on what is being built and what your approval requires.
The last certificate, and the one that matters at the end. It is issued once the final inspection has been passed and every compliance certificate has been received. Until it is issued the building may not lawfully be occupied, which generally also means it cannot be settled, let or insured as a completed dwelling.
We issue a Complying Development Certificate within 15 days of the lodgement date where the application is complete, and a Construction Certificate promptly once all required documentation is complete. In practice the timeline is set by how quickly the documents are gathered rather than by the assessment.
For a CDC: a title search, a section 10.7 planning certificate, the 88B instrument and any covenant on the title, a survey, architectural plans, structural plans and stormwater plans. For a Construction Certificate we also need the development consent and evidence that its pre-construction conditions have been satisfied.
It depends on the land and the design. Complying development is not available on every site — a heritage item or conservation area, certain flood or bushfire constraints, and some environmentally sensitive land can each exclude it, as can a covenant or easement on the title. Where a standard is missed, the project has to be redesigned to comply or lodged with council as a development application. Send us the address and the title documents and we will tell you which applies before you spend money on it.
Yes. The owner appoints the Principal Certifier, and that appointment is separate from who issued the CDC or Construction Certificate. We regularly take on projects approved elsewhere.
