ADU Rules
Accessory dwelling units (ADUs) are not subject to minimum lot area requirements, requirements for the number of dwelling units per acre, nor minimum parking requirements.
In districts where ADUs are allowed, the Code Enforcement Officer shall approve an ADU upon a determination that said ADU complies with the following conditions:
No more than one ADU is allowed per lot and an ADU may only be allowed where there exists only one single-family detached dwelling or one detached manufactured housing unit.
ADU square footage may not be more than 50% of the square footage of the principal dwelling or 1,000 square feet, whichever is less.. However, an ADU must be at least 190 square feet in size.
ADUs must meet the dimensional requirements and setbacks required for the principal dwelling, unless the Code allows for a reduced setback for accessory structures, in which case that setback shall apply.
ADUs contained within the principal dwelling below finished grade must have a daylight entry.
Manufactured housing, temporary camping vehicles, and mobile homes shall not be allowed as an ADU, except manufactured housing is allowed as an ADU in the Rural Residence and Agricultural District.
ADUs in areas not served by City sewer shall be treated as a separate dwelling unit for the purposes of septic design.
The ADU must be in compliance with all other laws and regulations.
