Private building certifier in Kiama Downs
CertifiBuild certifies houses, extensions, granny flats and backyard structures in Kiama Downs. Most owners first run into the gap between a big coastal outlook and what their own lot can actually fit.

Local rules
Kiama Downs homes from the beach to the hinterland
Family homes on their own blocks
Kiama Downs housing is almost all detached. Apartments make up a tiny share of homes here. So most work is a family improving its own house, whether that means extending at the back, adding upstairs, swapping the garage or upgrading the backyard. A big yard next door says little about your block, though. Width, drainage paths and the room remaining beside the existing garage all shape what can go where.
Coast on one side, hinterland on the other
Jones Beach faces north east, framed by Cathedral Rocks at one end and Minnamurra Headland at the other. That view is a strong pull for balconies and upstairs living rooms. Yet the suburb also stretches inland towards Jamberoo, so not every home is a beachfront home. Your survey should record the real orientation and exposure of the house rather than a postcard idea of it.
Where the council rules come in
If a development application (DA, a council approval) is needed, Kiama's Development Control Plan deals with how a house is designed, where building lines sit, and how height and bulk affect next door. A new balcony that frames the ocean can also overlook or shade the neighbour, and the assessment weighs both.

What owners build here
Kiama Downs jobs tend to be practical upgrades to a house the family already owns, rather than new builds on vacant land. These come up most often on our desk.
- Second storey additions chasing a coastal view, which need early thought about privacy, shading and structure.
- Rear extensions on established detached lots, planned around the current driveway, garage and drainage.
- Pools with an alfresco roof, ideally drawn together with the barrier, access and stormwater details.
- Granny flats, sized by the house being kept and the private open space remaining.
- Replacement garages and carports tied to a bigger house layout.
How approval usually works
Some Kiama Downs lots can use a CDC (a fast-track approval under state rules), while others need a DA, with a construction certificate to follow. Which applies depends on the mapping over your own lot, not your street or the nearby beach. Before lodging, have a surveyor plot the house, boundaries, existing garage and parking. Draw any upper addition against the neighbours' windows and yards, not only from the ocean side. If you plan a granny flat, mark how people and cars will reach both dwellings. Coastal exposure should also guide the engineering and materials for decks and roofs. CertifiBuild looks at the lot's mapping first, explains the pathway in plain terms and books inspections to suit your builder.

Local questions
Questions we hear about this suburb.
No two lots in Kiama Downs are the same. Give us your address and we will check every map that affects it.
See the council pageWill a second storey near Jones Beach upset my neighbours’ privacy?
It can, and that is why council assesses height, bulk and window position together. Where a development application (DA) is needed, Kiama’s Development Control Plan weighs overlooking and overshadowing of next door alongside your coastal outlook. Show the added storey beside the neighbours’ windows, living rooms and yards, not only from the side facing Jones Beach. Privacy screens, smaller or higher windows, or a reshaped balcony often settle concerns before lodging. Structure matters too, so have an engineer confirm the existing house can carry another floor.
Can I turn the old garage into a spare bedroom?
Possibly, but it needs approval and careful checking. A bedroom must meet habitable room standards, so the slab, walls, moisture protection, ceiling height and services all need assessing. The original garage approval does not cover living use. You also lose a parking space, so show on the plans where the car will go and how it reaches the street. On Kiama Downs lots, the existing driveway and drainage paths often shape this. Get a survey before deciding between a complying development certificate (CDC) and a development application (DA).
Does my neighbour’s granny flat mean I can build one too?
Not automatically. Every Kiama Downs lot is judged by its own size, width, zone and access, along with the private open space remaining around the house you keep. A granny flat down the street may have gone through a different pathway or been approved under older rules. Begin by surveying your block, marking the house, garage, car spaces and drainage paths, and show how people and cars will reach both dwellings. Then test the design against the state code or council’s controls for your address.
