Licensing. Carpentry is licensed residential building work in NSW. A contractor licence is needed for carpentry valued at more than $5,000 in labour and materials, GST included. The NSW Government defines carpentry as cutting and placing timber or timber composites for on-site construction, which takes in framing, stairs, doors, windows and floors, footings and structural support for pergolas, timber decks and fences, non-habitable shelters such as pergolas and gazebos, and formwork for concreting. It leaves out garages, sheds and carports, plasterboard (licensed separately as dry plastering) and concrete paths and slabs. The qualifications listed include the CPC30220 Certificate III in Carpentry.
Advertising and contracts. The state's guidance on building trade advertisements says the rules cover the internet as well as print, TV and radio. An ad has to show the licensee's name (a registered business name can stand in), the licence number with the correct category of work and a business phone number. It can't state part of a price unless the single full price is clearly stated too, and it can't mislead or hide a material fact. On the contract side, residential work over $5,000 needs a written contract and a copy of the Consumer Building Guide, a small jobs contract covers work up to $20,000 and a full home building contract applies above that, the deposit is capped at 10 percent, and contracts over $20,000 come with a Home Building Compensation certificate that owners are told to check before paying a deposit. A large roofed deck can reach that higher bracket, so a sentence on how you contract is worth having.
Approvals. Many small decks and pergolas in NSW are built as exempt development, with no planning or building approval, but only when they meet every standard. NSW Planning's fact sheet lists them: no more than 25 m² in area; a floor no higher than 1 m above existing ground; no more than 3 m at the highest point; behind the building line of any road frontage; at least 900 mm from the lot boundary, or 5 m in rural and large-lot residential zones; and a cap on all such structures on the lot of 15 percent of the house's ground floor area, or 25 m² on lots of 300 m² or less. A roofed structure attached to the house can't sit above its gutter line, a connection to the fascia has to follow an engineer's specifications, and roof water must go into the existing stormwater system. If a job can't meet all of that, the fact sheet says to get development approval from council first.
Bush fire prone land. Councils such as Northern Beaches and Ku-ring-gai map bush fire prone land; Ku-ring-gai's map takes in most vegetated areas and all land within a set distance of them. The NSW Planning guidance adds a condition for exempt decks and pergolas on that land: if the structure is within 5 m of a house, it has to be built from non-combustible material. Both councils note that their maps don't give a property's Bushfire Attack Level; a consultant's certificate or report states it, and both name AS 3959-2018, Construction of buildings in bushfire-prone areas, for development on mapped land. The NSW RFS runs an online tool, built from the councils' maps, that shows whether a property is mapped, and the council's planning certificate confirms it.
Our team works from Hutt St in Adelaide, so Sydney carpenters deal with us by phone and email. Two of our current clients are in Sydney: a tree service out west and a family dispute resolution practice. Send the licence details, a folder of finished jobs and your suburb list; the draft comes back as a link you can open on your phone, and payment waits until you've signed it off. We present what you tell us about your work and link to the official guidance for the rules; we don't give planning or legal advice.
