As the owner of a one or two family dwelling you may act as your own contractor and do the work yourself, provided that the home is for your own use, and is not for sale or lease. You must also do the work yourself, or provide direct on site supervision. If you are the owner of a commercial property, you are required to hire a contractor for any work that requires a permit and inspection. You will need to complete and sign an Owner/Builder Disclosure Statement and acknowledge that you understand your legal responsibilities (per Sec. 9-28 of the Fort Lauderdale Code of Ordinances).
