Riverside County, CA Short-Term Rentals: Night Caps (2026)

Riverside County Ordinance No. 927 does not impose an annual night cap or limit on the number of days per year a certified short-term rental may be rented in unincorporated areas. The only duration constraint is on the length of each individual stay: under Sections 4 and 8(d), an STR is rented for fewer than 30 consecutive calendar days but not less than two consecutive days and one night, with portions of calendar days counted as full days. This effectively prohibits one-night rentals. Rather than capping nights per property, the County controls saturation by capping the total number of certificates in its most-impacted areas (Section 9-11). Idyllwild (including Pine Cove) is capped at no more than 500 certificates, roughly 14% of its single-family units. In Temecula Valley Wine Country, the Winery District is capped at 114, the Equestrian District at 8, and the Residential District at 105. These areas also use density spacing-500 feet between rentals in Wine Country and 150 feet in Idyllwild-and select eligible properties through a tiered application and lottery process. Outside Idyllwild and Wine Country, there is currently no overall rental cap, no density spacing, and no per-property night limit, so a certified rental may operate year-round subject to the operational rules.
