Navigating Sutherland Shire Council Approval

A granny flat in the Sutherland Shire typically follows one of two approval paths. A Complying Development Certificate is the faster route for blocks that meet the standard planning rules. A Development Application through Sutherland Shire Council applies where a site sits within a special zone, such as a foreshore or environmentally sensitive area, which the Shire has more of than most regions.

As a guide, complying development requires at least 450 square metres of land, a 12 metre frontage, a 3 metre rear setback and 0.9 metre side setbacks. We assess your block properly, advise on the right path, and manage the full approval process so you avoid the guesswork.

What Will Your Granny Flat Cost in the Sutherland Shire?

The cost of a granny flat in the Sutherland Shire reflects your design, your site and the finishes you choose. Premium finishes and more complex sites, including sloping or foreshore blocks, influence the final figure. We quote after inspecting your property so the price is accurate and complete, with a clear itemised breakdown and no hidden extras.

Given the high property values across the Shire, many homeowners view a granny flat as a value-adding improvement rather than a cost. A quality second dwelling can lift the overall worth of your property and broaden its appeal to future buyers, on top of any rental income it earns. We are happy to talk through the numbers for your specific block so you can make a confident, informed decision.
