Fairfield, CA Parking Rules: Overnight Parking (2026)

Unlike some cities that prohibit overnight parking entirely, Fairfield allows passenger cars to park overnight on most public streets subject only to the 72-hour limit and to any posted permit or restriction signs (Municipal Code Chapter 11). Some residential neighborhoods near schools, parks, and apartment complexes have signed permit-parking districts; check signage on your block. Most municipal parking lots (downtown, Allan Witt Park, civic center) close overnight (typically 10 p.m. to 5 a.m.) and posted signs prohibit overnight parking there. Park-and-ride lots maintained by Fairfield-Suisun Transit are also typically not for overnight storage. RVs, oversized vehicles, and commercial vehicles cannot park overnight on residential streets except under the narrow 72-hour twice-per-week exception for boats/RVs serving an abutting resident. Using a vehicle for human habitation on a public street or public parking lot is prohibited; Fairfield runs a Safe Parking Program (Municipal Code Chapter 5E) at designated locations for unhoused individuals.
