The Simi Valley short-term rental ordinance approved on first reading May 11, 2026 caps overnight occupancy at two adults per bedroom (children are not counted), bans all events and parties, and requires neighbor notification for unhosted units. Until the ordinance becomes effective on January 1, 2027, there is no city-specific guest cap, and the California Building Code (Title 24 CCR) occupant-load default applies.
Under the ordinance approved on first reading, the maximum overnight capacity at any Simi Valley STR will be 'two adults per bedroom. Children would not be included in the count,' according to the City's December 2025 staff presentation to City Council. The ordinance also bans events and parties outright, requires noise monitoring at the property, and mandates that operators of unhosted (whole-home) STRs notify property owners within a 200-foot radius. Until January 1, 2027, no Simi Valley ordinance imposes a specific overnight guest cap on residential rentals; California Health & Safety Code Section 17922, which incorporates the California Building Standards Code (Title 24 CCR), sets minimum room sizes and occupant-load requirements (CRC R304 / CBC Table 1004.5) that govern in the absence of a local rule. The City's nighttime noise rule in Simi Valley Municipal Code Section 5-16.02 (10:00 p.m. - 7:00 a.m. Sunday through Thursday; 11:00 p.m. - 7:00 a.m. Friday/Saturday) applies to STR guests immediately and will be the principal tool for breaking up oversized gatherings until the new ordinance takes effect.
After January 1, 2027, exceeding the two-adults-per-bedroom cap, hosting an event or party, or failing to send neighbor notice for an unhosted unit will trigger administrative citations and progressive fines (the City discussed $1,500 to $5,000 annual fines for repeat violations in the December 2025 staff presentation), and may be grounds for permit non-renewal. Noise-related occupancy disturbances are already citable under Simi Valley Municipal Code Section 5-16.02 with potential infraction or misdemeanor exposure under the SVMC's general penalty provisions.
