From what they do to how the process of approval with a private building certifier Sydney wide works for granny flats, this guide outlines everything you need to know.

What Is a Private Certifier and Why Does It Matter for Granny Flats?

A private certifier is an independent, accredited professional who checks the construction against the National Construction Code and other NSW planning policies. A private certifier Sydney property owners hire is different from a council certifier in that they’re employed on a commercial basis, which means a quick turnaround time and a clear line of communication throughout your project.

Most granny flat projects in NSW are considered to be within the Complying Development Certificate (CDC) pathway. This is due to the Housing State Environmental Planning Policy that regulates granny flats, also known as secondary dwellings. Qualifying granny flat projects can be assessed by a private building certifier Sydney wide in a matter of months instead of many months via council for a full Development Application.

The CDC Pathway: How Granny Flats Get Approved Faster

This complying development pathway was created for simple residential works to ease the red tape. There are a number of criteria your property must meet to be eligible for a granny flat, including the actual size of the lot and the internal habitable area of the second dwelling.There are a number of conditions that your property must meet for it to be eligible to have a granny flat: size of the lot and the size of the internal habitable area of the second dwelling. Beyond that cap, there are additional allowances for covered parking, entry porches and outdoor living space.

A private certifier Sydney can issue the CDC without any involvement of the council once the design has passed the prescribed development requirements, such as setbacks, height limits, landscaped area, and parking requirements. This can be a huge benefit to the homeowner who does not want to deal with the uncertainty and lengthy assessment timeframes associated with a traditional DA.

Not all properties are necessarily eligible, of course. Flooding, bushfire risk and heritage listed sites are typically not part of the complying development framework and must be submitted as a complete Development Application. When hiring a private building certifier Sydney early stages of the process, these guys can tell you which option is best suited for your block and you won’t have to spend time, money and effort on a design that is not going to be accepted.

What a Private Certifier Actually Does on a Granny Flat Project

Many homeowners think that a certifier only arrives at the end of the project to sign off on the completed build. But in fact, they play a role on the whole project life. A private certifier Sydney owners work with will be on your site early on to survey your site against planning controls, review your architectural and structural plans, and confirm that your project meets the ‘complying development’ requirements or that it requires a different pathway to be approved.

After construction starts, the certifier is required to perform inspection(s) at critical points, including after excavation, frame stage and prior to covering the waterproofing or structural elements. The checkpoints ensure that the build remains in line with approved plans and meets the Building Code of Australia. A lack of inspections or missing out might even prevent building from happening altogether, so it’s crucial to engage a private building certifier Sydney wide right from the beginning.

Once the project is completed, the certifier will present an Occupation Certificate, which officially certifies that your granny flat has passed the inspection and is safe and ready to occupy. This certificate is required to make the dwelling legally habitable and/or lawfully leasable even if it is completed and looks good.

Why Choosing the Right Certifier Makes a Real Difference

All certification experiences are not equal. A responsive private certifier Sydney developers and homeowners can build a relationship with will be able to effectively communicate, identify potential compliance issues before they become expensive, and help to move your project along without unnecessary back and forth. Alternatively, a tardy certifier or someone who doesn’t know your local council overlays can unobtrusively extend your process by weeks.

Be sure to check if they are accredited by NSW Fair Trading, a member of a recognised industry body and have experience specifically in secondary dwellings – not just larger commercial projects. Inquire about their experience at bush fires and flood affected sites as they will need extra reporting and technical knowledge. A private building certifier Sydney wide, with authentic granny flat experience, will also be aware of the intricacies of shared services, easements and BASIX sustainability requirements that often leave first-time granny flat applications at a disadvantage.

Common Mistakes Homeowners Make Without Early Certifier Involvement

So one of the main problems we get is consumers finalising on a design prior to determining if their block is suitable for complying development. This may involve paying twice for drawings that are drawn up first as a CDC compliant design and then again as a full DA if the lot does not fall within the 450m² limit or is located in a flood or bushfire overlay.

One of the other common mistakes made is assuming that any builder has the knowledge to self certify their own work. The independent private certifier, which is recognised by NSW authorities, is required to be independent of your builder, and impartial to ensure that inspections are truly independent. Having a certifier on board at the design stage—before plans are complete, not after—is always the key to a smooth approval and frustrating series of resubmissions.

Bringing It All Together

Granny flats are one of the most readily available methods to increase value and living space in the Sydney real estate market, primarily because the complying development pathway offers a quicker approval process than a DA. However, so long as the correct pro is leading the way. Having an experienced private certifier Sydney homeowners can trust will take them from start to finish of an Occupation Certificate on a Granny flat project will keep a project on track and ensure full compliance with NSW regulations.
