Illawarra & Southern Highlands
Private building certifier in the Wingecarribee Shire Council area
CertifiBuild certifies homes, additions, farm sheds and garages across Wingecarribee Shire. Almost the whole shire drains into Sydney’s drinking water supply. So the key local issue is showing your project will not harm water quality.

Local rules
What shapes approvals here.
Protecting the drinking water catchment
Nearly all of the Southern Highlands drains to Sydney's drinking water supply. Where your project needs consent, it must not make water quality worse, and ideally improves it. This applies to every site, not just some. In practice, you need a water quality assessment. It covers stormwater and, on land without sewer, on-site wastewater treatment. Where the assessment calls for it, WaterNSW may need to give its agreement.
Wastewater can limit house size
On rural residential lots, wastewater is often the deciding factor. The soil's ability to absorb treated effluent matters. So do setbacks from creeks and other watercourses. Between them, these can cap the size of a house and decide its position. We work through these limits while the footprint can still move. Servicing must be resolved before a construction certificate can be issued. That certificate approves the detailed building plans.
Finding the right rules
The Wingecarribee Local Environmental Plan (LEP) 2010 is the shire's main planning rulebook. Rather than a single development control plan (DCP), there are about seventeen. Each one covers a type of land, such as rural land or rural living. We find the correct one early, and confirm the zoning and smallest permitted lot size alongside it.
Bushfire and approvals
Nearly every suburb has some bushfire prone land. A bushfire attack level (BAL) assessment decides how the home must be built. Flame Zone or BAL-40 ratings mean a complying development certificate (CDC) cannot be used. A development application (DA) to council is then needed. The 2021 Census counted 90.4% of homes here as separate houses. To start, send us your survey, plans and planning certificate so we can check water, wastewater and bushfire needs.
Local know-how
Southern Highlands towns and the rules that shape them
Bowral and Berrima
Both towns have detailed heritage rules for older cottages. Within their conservation areas, the expected form is one storey under a pitched roof. Extra rooms usually go in the roof space with dormers, rather than a full upper floor. Berrima also limits new buildings to 3.6 metres from natural ground to the eaves. For bigger additions, a linked rear pavilion is a common answer.
Within Bowral's conservation areas, garages must be set back 1.5 metres or more from the front wall. Hard paving across the front yard is capped at 20% of that area. A pool or detached shed may still fit the state code there, but a listed item faces more limits.
Mittagong
Mittagong has quite different settings. The central heritage streets protect cottage scale, verandahs and chimneys. On the Mount Gibraltar slopes, homes sit within large gardens and bush, and buildings should not rise above the tree line. The driveway, earthworks and house are planned together there.
Moss Vale
The township DCP lists several redevelopment precincts, among them Kirkham Street and Elizabeth Street South. A second dwelling there should let cars leave the site driving forwards. The turning area can swallow much of the backyard, so we test it before floor plans are drawn.
Robertson
Robertson's town blocks were first sold in 1865, and remnant Yarrawa Brush rainforest still grows nearby. Some 95% of Robertson is shown as bushfire prone on the map. Its village DCP recognises that certain infill lots are difficult to design for. That flexibility works through a DA only, not a code-based approval.
Why Highlands owners and builders choose CertifiBuild
CertifiBuild knows that each Highlands town has its own township or village DCP. We confirm which one applies, and whether heritage or bushfire mapping affects the lot, before your design is locked in. We understand how those local plans sit alongside the state codes for houses, pools and outbuildings. We reply promptly and fit inspections around your builder's program. We work only on homes and Class 10 structures, including carports, garages, decks and sheds.

All council areasWhat is the water quality test for building in the Southern Highlands?
In the Southern Highlands, any project that needs development consent must show it will not make water quality worse, and ideally will improve it. This applies because nearly the whole of Wingecarribee Shire lies in the catchment supplying Sydney’s drinking water. Every site is therefore covered. In practice you provide a water quality assessment dealing with stormwater and, where there is no sewer, on-site wastewater treatment. WaterNSW may need to agree where the assessment calls for it. Raise this with your designer early, as stormwater and effluent areas affect the site layout.
Can wastewater limit my new home near Robertson?
Yes. On rural residential lots around Robertson, wastewater is often the deciding factor for a new home. How well the soil absorbs treated effluent, along with setbacks needed from creeks and other watercourses, can cap the house size and fix where it sits. Servicing must be sorted out before the detailed plans can receive a construction certificate. Robertson also has extensive bushfire mapping, with about 95% of the town shown as bushfire prone. Get the wastewater assessment done first, and we will work through the limits while the footprint can still move.
Which DCP covers my property in Bowral or Moss Vale?
That turns on what kind of land your property is. Wingecarribee has about seventeen development control plans (DCPs) rather than one, each covering a land type such as rural land or rural living, and the Highlands towns have their own township DCPs. In Bowral, conservation area rules shape garage setbacks and front paving. In Moss Vale, the township DCP names redevelopment precincts such as Kirkham Street and Elizabeth Street South. We confirm the right DCP early, along with the zoning and smallest permitted lot size under the Wingecarribee Local Environmental Plan (LEP) 2010.
