Process |
ADUs on the ground floor require a building permit, while second story ADUs require a planning entitlement in addition to the building permit. No deed restrictions are required. Making an appointment to meet with a planner in the initial stages of the project can help avoid challenges and is highly recommended. |
Exceptions |
People with disabilities may apply for a waiver of the rules. |
Disclaimer: standards and process may vary. Consultation with the contact is recommended before starting any project.
*Detached ADUs are typically subject to building fees, impact fees and school fees. Attached ADUs are subject to the same fees plus an entitlement fee for second story units. Fees are specific to each project and will vary. Fees change regularly. These are provided as examples only.
