Put together an all-inclusive budget so that you can determine if it is feasible to take on an ADU project given all of the factors involved. Use tools like our ADU Calculator as a guide only - every situation is different. Make sure not to overlook the additional cost of utility bills, insurance and property taxes that you will incur. Also consider the cost of items outside of the building like parking pads and landscaping.

Meet with several design-build firms and licensed General Contractors experienced with ADUs and share your vision and budget with them. Ask to see their portfolio of completed work. Talk to homeowners they've worked with if possible. Decide who you feel most comfortable working with and ask them for a formal quotation.
