Illawarra & Southern Highlands
Private building certifier in the Shellharbour City Council area
CertifiBuild certifies new homes, pools, garages and patios across Shellharbour. Around Lake Illawarra, the key local issue is flooding. A coastal lake can rise from rain, tides and the sea, so flood levels are settled early.

Local rules
What shapes approvals here.
How Lake Illawarra floods
Lake Illawarra, a big coastal lagoon, sits at the heart of Shellharbour. Its water level depends on catchment rain, the lake entrance and ocean conditions. That means low land near the lake can be flooded by several sources. Council manages flood risk for the lake and for Macquarie Rivulet. Flood and stormwater rules sit in its development control plan (DCP), which holds detailed design rules. On a lakeside lot, we confirm the flood level and the required freeboard before any approval is issued. Freeboard is the extra height added above the flood level.
New estates have their own rules
Calderwood is a growing release area with its own planning provisions outside the council DCP. Tullimbar has its own part within the DCP. The Shellharbour Local Environmental Plan (LEP) 2013 is the main planning rulebook across the area. We confirm which rules cover your lot before assessing plans.
Bushfire is common too
Bushfire prone land is found in most suburbs, from the escarpment to the Calderwood area. On mapped lots, a bushfire attack level (BAL) assessment decides how the home must be built. Housing work with the two highest ratings, Flame Zone or BAL-40, cannot use a code-based approval.
CDC or DA?
A complying development certificate (CDC) is a code-based approval a private certifier can issue. Your planning certificate shows if the lot is a flood control lot. If it is, the code's flood rules must be met. Otherwise, a development application (DA) goes to council. In Census 2021, 79.7 per cent of homes here were separate houses. For a next step, send us your survey, plans and planning certificate so we can check flood and bushfire maps.
Local know-how
Around Shellharbour: what changes from street to street
Shellharbour Village
The old village keeps its nineteenth century port layout, a small harbour and verandahs on posts. The DCP treats it as a design setting of its own, apart from the newer City Centre. A foreshore heritage conservation area sits nearby. Upper level additions are common requests. Some public views toward the harbour are protected. A new balcony may need drawings of its street appearance, not only the inside view.
Shell Cove
Shell Cove was built in stages, and each stage can carry its own rules. Some lots next to the golf course carry roof form rules, and some boundaries carry fencing rules. Certain properties also have noise mitigation restrictions on their titles. Changing windows or an external wall on those lots must keep that protection. We check the title and stage plan before a roof or window package is selected.
Oak Flats and Warilla
Oak Flats was planned in the 1920s on garden city principles. Its streets circle Knob Hill, and Central Avenue lines up with wider landscape views. Council aims to keep that street pattern and the lake views. Some land on The Boulevarde carries a special building line, which is measured off the street front. In Warilla, some Little Lake Crescent land has its own building line table. Either line is plotted on a survey before new rooms or decks are placed.
Albion Park
Albion Park grew around a crossroads, with a showground and older civic buildings. Front building lines for homes near the town centre may differ from those elsewhere in the suburb. Next to a heritage item, a second storey needs careful siting. Separate houses dominate here, so the usual jobs are extensions, knockdown rebuilds, garages and pools.
Why Shellharbour owners and builders work with CertifiBuild
CertifiBuild is familiar with how Shellharbour's DCP shifts between village, estate and lakeside streets. We check stage documents, title restrictions and special building lines for each property early. We know how council's controls work alongside the state codes. Owners and builders get prompt answers, and we schedule inspections around each stage of the build. We work only on homes and Class 10 structures, including granny flats, garages, patios and pools.

Local questions
Questions we hear in this area.
No two lots are alike. Share your address and we will review the maps that cover it.
All council areasWhy can my Warilla lot flood from different directions?
Because Lake Illawarra is a coastal lagoon, its water level responds to several things at once. Heavy rain across the catchment, whether the lake entrance is open, and ocean conditions can all push water onto low land around Warilla. Council runs flood risk management covering Macquarie Rivulet as well as the lake, and its development control plan (DCP) holds the flood and stormwater rules. On a lakeside lot, we confirm the flood level and the freeboard, the extra height above it, before any approval issues. Your planning certificate will say if the property is a flood control lot.
Does the council DCP cover a new home I am building in Calderwood?
No. Calderwood is a growing release area with its own planning provisions, and it sits outside the Shellharbour development control plan (DCP). Tullimbar is handled differently, with its own part inside the DCP. The Shellharbour Local Environmental Plan (LEP) 2013 still applies across both areas. Bushfire prone land also reaches into the Calderwood area, so a bushfire attack level (BAL) assessment may shape how the house is built. Before you lock in a house design, let us confirm which rules cover your Calderwood lot and whether a code-based approval suits it.
Is bushfire a concern for a new Shellharbour house?
In most Shellharbour suburbs, yes. Bushfire prone land runs from the escarpment edge across to the Calderwood area. For a mapped lot, a bushfire attack level (BAL) assessment rates the exposure and decides the building standard the house must meet. Housing work rated Flame Zone or BAL-40 cannot use a complying development certificate (CDC), so a development application (DA) goes to council. Many lots near Lake Illawarra also need flood checks. Send us your survey, plans and planning certificate, and we will look at both maps together.
