Accessory Dwelling Unit Handbook - Updated July 2022

New policies are making ADUs even more affordable to build, in part by limiting the development impact fees that local jurisdictions may charge for ADU construction and relaxing local zoning requirements. ADUs and JADUs can often be built at a fraction of the price of a new single-family home, and homeowners may use their existing lot to create additional housing. Often the rent generated from the ADU can pay for the entire project in a matter of years.
