If you want to learn how to start a housing construction business in NSW, you can use this page as a guide to get you started.
You may need to complete only some of these transactions, depending on your business needs. For example, you can apply for a construction induction card without needing a high risk work licence. If you're undertaking specialist building work, such as plumbing or electrical wiring, you may need to apply for additional licences from NSW Fair Trading.
Before you invest time and money into setting up your business by registering and applying for the right business licences, make sure you put together a business plan and carefully consider how viable your business is. Many businesses fail when these things aren't considered. Get in touch with the Office of the NSW Small Business Commissioner or an industry association to get advice specific to your area.
Consider this list an ideal starting point to find out what's relevant to starting your housing construction business.
