South of the border the state rules are those that apply in Sydney: a Building Commission NSW licence whose name, number and category appear in all advertising, the internet included; a deposit capped at 10 percent; and Home Building Compensation cover before any deposit on residential work over twenty thousand dollars. Our Sydney builders page has the detail. North of it, the QBCC sets its own advertising requirements, explained on our Gold Coast builders page. Neither state's licence simply works in the other: general building work isn't due to come under NSW's automatic mutual recognition scheme until 1 October 2027, and before then a Queensland licensee has to apply to Building Commission NSW to have the licence recognised, just as an NSW licensee applies to the QBCC under mutual recognition to work on the Queensland side. The website should show the licences you actually hold, each with its state.
Flood planning is where the Tweed differs most. Section A3 of the Tweed Development Control Plan, the part on flood liable land, moved to version 1.7 on 4 March 2026 after a council resolution on 12 February. That version revises the defined flood event, the flood planning levels and the related controls to match the 2024 Tweed Valley Flood Study Update and Expansion and the 2025 Interim Flood Planning Levels Policy, replaces the 1984 maps of inappropriate development with modern maps covering the whole shire, and brings the section into line with the NSW Flood Risk Management Manual 2024. The defined flood event is now the highest of several levels, among them the flood of record (the 2022 peak, for example) and, as an allowance for climate change, the 0.2 percent AEP flood from the 2024 study. The flood planning level adds 0.5 metres of freeboard to that, and it sets the minimum habitable floor level. Any floor height a builder's site quoted from before March 2026 may now be wrong, and quoting heights at all is best left to council's property flood reports.
Extensions are handled carefully. Under the same section, a minor extension to an existing single dwelling means adding no more than 35 square metres. Where a home's lowest approved habitable floor is below the flood planning level, a minor habitable extension can be allowed only if it's outside high flow and high hazard areas, doesn't open the way to a dual occupancy or to turning a garage or other non-habitable space into rooms, respects any earlier floor-area limits, and is built to a flood resilient design with flood compatible materials up to the planning level. Larger additions need a split-level design that reaches the planning level. The DCP also names filled estates in Banora Point, West Kingscliff and Pottsville, and raised homes in Chinderah, South Murwillumbah and rural villages, as examples of low islands that can be cut off and then covered in the biggest floods. A builder whose site says plainly that it checks these rules before designing an addition gives owners in those suburbs a reason to call.
Recovery work continues. The Tweed is one of seven Northern Rivers council areas in the NSW Reconstruction Authority's Resilient Homes Program; applications for raising and retrofit grants closed on 14 August 2026, and in June 2026 the government gave participants until December 2028 to finish raising or retrofitting, citing well documented capacity constraints in the region's building market. Our Tweed Heads tradies page has more on how that program works. Council has operated flood levees across the Tweed since the 1950s, Tweed Heads South among them, and a 2026 levee and drainage study looks at flooding and drainage in Tweed Heads South and Banora Point.
New streets are going in too. Kings Forest, near Kingscliff, has a concept plan approved in 2010 for 4,500 dwellings, and its first lots were released for sale in December 2023; Cobaki, just west of Gold Coast Airport, is planned for about 5,500 homes with buildings capped at three storeys. Master Builders NSW's Tweed division covers the NSW side of the Gold Coast region and inland to Murwillumbah, with quarterly information nights around the shire, and its Northern Regions Excellence in Building Awards take entries for 2027 until 21 February, with the gala at Ballina RSL Club in June. We're an Adelaide team on Hutt St; Tweed builders work with us by phone and email, and one of our Queensland clients is M.J. Debney Plumbing & Gas. Send your licence details, finished projects and the towns you build in, and we'll reply with a draft link. You pay once you approve it.
