Beaumont, CA Accessory Structures: ADU Owner Occupancy (2026)

Section 17.15.070 of the Beaumont Municipal Code sets the additional standards for junior accessory dwelling units (JADUs) in the City of Beaumont, Riverside County, adopted through Ordinance Nos. 1149 and 1150 on October 4, 2022. Subsection A is the owner-occupancy rule. A natural person with legal or equitable title to the property must reside on the property, in either the primary dwelling or the JADU, as the person's legal domicile and permanent residence. The owner can live in the main house and rent the JADU, or live in the JADU and rent the main house, but someone holding title must be living on the lot.

The exemption is narrow. The requirement does not apply if the property is entirely owned by another governmental agency, land trust, or housing organization. An investor-owned lot, an LLC-owned lot or a lot with a non-resident individual owner is not exempt under the text.

The rule is attached to JADUs. Section 17.15.060, which holds the additional standards for full ADUs (maximum size, setbacks, height, parking and design), contains no owner-occupancy standard, and the owner-occupancy language appears only in 17.15.070. Section 17.15.030.A allows one JADU alongside one ADU on a lot with an existing or proposed single-family dwelling, so the requirement follows the JADU wherever a lot has one.

Subsections B and C round out the JADU standards. A JADU must have both interior access to the primary dwelling unit and an exterior door, and parking is not required for a JADU. Related rules in Section 17.15.050 set a minimum size of 150 square feet for an ADU or JADU, bar the exterior entry of a JADU from the front of the primary unit, and require a deed restriction recorded with the Riverside County recorder's office before any certificate of occupancy. Section 17.15.040.A requires plot plan approval by the Community Development Director and a building permit for every JADU.
