Pittsburg, CA Short-Term Rentals: Occupancy Limits (2026)

With no dedicated STR ordinance, Pittsburg relies on state and uniform codes to determine legal occupancy. The 2022 California Residential Code requires that every sleeping room have at least 70 square feet of floor area for one occupant and 50 square feet per additional occupant, and habitable rooms must have a minimum ceiling height of 7 feet. California Health and Safety Code section 17920.3 classifies overcrowded dwellings as substandard housing, and local code enforcement can act on complaints of excessive occupancy. The common industry rule adopted by Airbnb and Vrbo is two guests per bedroom plus two, which aligns with the HUD guideline of two persons per bedroom used to screen for fair housing compliance. Hosts should never advertise capacity beyond what bedroom count and floor area can legally support, and they should list a specific maximum guest number in the rental listing. Pittsburg code enforcement responds to neighbor complaints about overcrowding, excessive noise, or parking impacts, and documented overcrowding can trigger abatement action under the state housing code. Fire code maximum occupancy rules for one-and two-family dwellings are generally less restrictive than for commercial lodging, but fire sprinklers, smoke alarms, and carbon monoxide alarms must be operational.
