General planning information.
The website provides general information about ADU construction and project planning. It is not a construction proposal, permit approval, engineering document, or guarantee of a property's eligibility. Requirements and program information can change. Refer to the current City sources and responsible professionals for the proposed work.
Design references and project agreements.
Images illustrate architectural and interior design directions. They do not establish a completed-project portfolio, an approved plan, or a product specification. Any construction engagement requires a separate agreement identifying the responsible contractor, scope, terms, and applicable credentials.
Phone contact and the project brief.
Phone contact is available at (949) 503-8004. You can also leave your name and number in the estimate request form and we get back to you fast. A call, a request, or a downloaded brief does not reserve an appointment, provide a referral, or create a construction agreement. You decide whether and with whom to share the file.
