Start with Feasibility

It all starts with site visit and feasibility report.

Do you want to know what the most frequent mistake is we see homeowners make? They dive into design of the ADU floor plan and architectural drawings for their ADU homes before checking the zoning and site constraints. Do not miss this step. It might look like you are saving money, but it will come to bite you afterwards.

You cannot save money during construction. In fact, you can not save money after submitting for permit. All savings are made at the planning and design stage.
