Can I convert an existing garage or other structure on my property into an ADU?

State law allows homeowners the right to convert many types of existing space into ADUs. The state law covers garages, other accessory buildings (like art studios), or even part of the main house, including attics and basements. To qualify, your property must meet the following criteria:

• The house must be located in a single-family zone.
• The structure must have been built legally initially.
• The ADU must have a door that provides direct access to the outside. (This door can be added during construction if it is not there in the existing structure.)
• The existing structure must be far enough away from the property line to not be a fire hazard. Discuss specifics with the county.
