Under RMC §19.442.030, ADUs, JADUs and MADUs in Riverside may only be rented for terms longer than 30 days — short-term vacation rentals are prohibited. This mirrors the local-agency authority granted by California Government Code §66314(a)(6).
Riverside's ADU ordinance expressly states that ADUs, MADUs and JADUs 'when rented, must be used for rentals of terms longer than 30 days.' This forecloses Airbnb, VRBO, and similar transient occupancies. The 30-day floor is the maximum local restriction allowed under California Gov. Code §66314(a)(6) (re-codified from former §65852.2). The city's separate short-term rental program (RMC Chapter 5.66) does not authorize STR use of an ADU; an STR permit covers only the primary dwelling. Violations of the 30-day minimum are enforced both as a zoning violation (RMC Title 19) and, where the unit is advertised online, as an unpermitted STR.
Operating an ADU as a short-term rental violates RMC §19.442.030 and is subject to administrative citations under RMC §1.17: $100 first offense, $500 second, and $1,000 per day for continued violations involving building/zoning code under Gov. Code §36900(c). The city may also seek injunctive relief and recover enforcement costs.
