Accessory Dwelling Units  |  Housing Supply Planning

The county’s zoning code permits internal, attached, and detached accessory dwelling units (ADUs) by right in rural and residential districts, subject to use-specific standards (§18.7.D).  These standards address owner occupancy, lot size, units per lot, methods of creation, unit size, unit height and setbacks, home occupations, transient uses, parking and driveways, exterior appearance, variances and existing conditional use permits, other regulations and codes, enforcement and revocation, and the process for applying for a discretionary ADU permit authorizing deviations from standards.
