A property owner of a one- or two-family residence can obtain all required permits to construct, alter, add, improve, or repair the principal place of residence or appurtenances thereto, where none of the improvements are intended for sale within one year after completion.
An owner-builder indicates: a person who owns the property and acts as their own general contractor on the job, and either does the work themselves or has employees (or subcontractors) working on the project. Please review the risks of being an owner-builder.
The work site must be their principal place of residence that they have occupied for 12 months prior to completion of the work. The homeowner cannot construct and then sell more than two structures during any three-year period. CA Business & Professions Code section 7044 has more information about owner-builders.
