These are both site-built and prefabricated plans that have been pre-reviewed for compliance with applicable building code requirements. It is crucial that you begin by first contacting your local jurisdiction to understand what is and is not possible on your site before you proceed with selecting a plan. You should also ask your jurisdiction about their policy for use of pre-reviewed plans, as each individual city and county is unique.
NOTE: A pre-reviewed plan will require additional information and tailoring before it can be submitted to your jurisdiction for ADU permit approval. See FAQs page for more details.
