Beaumont, CA Accessory Structures: ADU Rental Restrictions (2026)

Section 17.15.050 of the Beaumont Municipal Code sets the general requirements for accessory dwelling units and junior accessory dwelling units in the City of Beaumont, Riverside County. Subsection A opens by confirming that an ADU or JADU can be rented. What it forbids is separate ownership: no ADU or JADU can be sold or otherwise conveyed separately from the primary dwelling unit, and the lot cannot be subdivided. The one carve-out is a property built or developed by a qualified nonprofit corporation where all provisions of Government Code Section 65852.26 are met.

Subsection B is the short-term rental rule, and it is a flat prohibition: no ADU or JADU can be rented for a term shorter than 30 days. That rules out nightly and weekly vacation rentals of these units in Beaumont, while month-to-month and longer tenancies remain allowed. The subsection sets no rent level, and it applies to attached and detached ADUs and to JADUs alike.

Subsection K backs the no-separate-sale rule with a recorded instrument. A deed restriction must be recorded against the lot containing the ADU or JADU with the Riverside County recorder's office before any certificate of occupancy is issued for the unit. The restriction runs with the land and can be enforced against future property owners. Among other requirements, it must state that the ADU or JADU cannot be transferred or sold separately from the primary dwelling, and the City provides the form.

Subsection J adds a monitoring element. The owner of the lot is requested, not required, to participate in the City's monitoring program that tracks rent levels of ADUs and JADUs for the City's Regional Housing Needs Allocation reporting. Subsection L covers the end of the unit's life: if an ADU or JADU is removed or converted to another use after a certificate of occupancy, deviations from development standards and any reduced or exempt fees must be brought into compliance with the rules then in effect, and the City rescinds the deed restriction only upon approving the reversion request.
