Summary

Chino requires the property owner to live on-site at any single-family home with a junior accessory dwelling unit, with an exemption for government agencies, land trusts, or housing organizations.

10.Junior accessory dwelling units - owner occupancy. The property owner must reside in any single-family residence that includes a junior accessory dwelling unit. The owner may reside in either the junior accessory dwelling unit or the remaining portion of the structure. However, owner-occupancy is not required if the owner is a government agency, land trust, or housing organization.

11.Junior accessory dwelling units - deed restriction. The approval of a junior accessory dwelling unit will be conditioned on the recordation of a deed restriction, which shall run with the land, and will be recorded by the city on the property where unit is, or will be, located. The deed restriction will include the following:

(a)A prohibition on the sale of the junior accessory dwelling unit separate from the sale of the single-family residence, including a statement that the deed restriction may be enforced against future purchasers.(b)A restriction on the size and attributes of the junior accessory dwelling unit that conforms with Government Code section 65852.22. (Ord. 2020-006, § 10, 2020; Ord. 2021-001, § 9, 2021; Ord. 2022-010, § 8, 7-19-2022.)

Full Breakdown

Chino Municipal Code § 20.11.020(B)(10) imposes owner-occupancy only on junior accessory dwelling units (JADUs), not on full-size accessory dwelling units. The owner must reside somewhere on the property, either in the JADU itself or in the remaining part of the main house, but a government agency, land trust, or housing organization that owns the property is exempt from the requirement. This tracks California ADU law, which allows cities to require owner-occupancy for JADUs even though it generally bars owner-occupancy mandates for standalone ADUs.

Violations & Fines

A single-family property with a JADU where the owner does not reside on-site (and isn't a government agency, land trust, or housing organization) is out of compliance with § 20.11.020(B)(10).
