CHANGES To ADU Development Standards & Requirements!

On January 1, 2020, new state regulations for Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) went into effect with the intended purpose of easing local zoning controls, reducing associated development fees, and streamlining the permit process. The new legislation expressly limits a local agency’s ability to regulate ADUs and JADUs and puts most local ADU/JADU ordinances in conflict with the State’s new laws.

Planning Division staff will be updating the County’s existing ADU ordinances to be compliant with the State’s regulations. Until that time, all ADU/JADU permit applications will be reviewed using both the County’s existing development standards and, where applicable, the State’s revised development standards to verify consistency with State law. Draft amendments to both the Non-Coastal and Coastal Zoning Ordinances are being prepared to comply with the new State regulations. Development standards associated with parking, JADUs, owner occupancy requirements, and others will be amended to reflect changes made at the state level.

Current State law regarding Accessory Dwelling Units can be found on the State of California’s Legislative Information website. If you would like to be added to an Interested Parties List to receive notification when the ADU ordinances go to public hearing, please visit the Planning Division Accessory Dwelling Unit Ordinance Update webpage and register here: https://www.vcrma.org/accessory-dwelling-unit-ordinance-update

If your lot is located in the coastal area, the proposed ADU must comply with the Coastal Zoning Ordinance Section 8175-5.1.1. The ordinance is available here.

ADU/JADU Affidavits

For an ADU or JADU, the owner(s) of the property must agree that if the unit is to be rented out at any time, it will be for longer than 30 consecutive days. For a JADU, the owner of the property must also agree to reside in either the principal residence or JADU. An ADU affidavit or JADU affidavit agreeing to these terms must be submitted at the time of application.

To determine the type of permit required for your ADU, see the flow chart below.
