Summary

Fremont bans generator use during quiet hours at permitted safe parking host sites. Municipal Code Sec. 18.190.475(d)(12) sets quiet hours from 10:00 p.m. to 7:00 a.m. and prohibits generators entirely during that window, part of the performance standards the zoning administrator enforces before issuing a safe parking host site permit.

Full Breakdown

Fremont's zoning code regulates safe parking host sites, which are ministerial-permit uses that let churches, quasi-public facilities, and public facilities host people living in vehicles. , and generators are flatly prohibited during those hours, with no exception carved out in the text. This sits alongside other performance standards in the same subsection: sites are capped at 20 inhabited vehicles at a time (d)(5), must provide restrooms, potable water, and trash facilities (d)(6), maintain vehicle-to-vehicle clearances of 8 feet for cars/vans and 16 feet for RVs (d)(7), keep setbacks of 20 feet (cars/vans) or 40 feet (RVs) from residentially designated property lines (d)(10), and post fire extinguishers within 75 feet of every inhabited vehicle (d)(8).

The community development department reviews the site management and operations plan before the zoning administrator or designee issues the one-year, renewable ministerial permit under subsection (c). is grounds for the city to deny renewal or pursue code enforcement against the permit holder, not just the individual vehicle occupant.

Violations & Fines

Running a generator between 10:00 p.m. and 7:00 a.m. at a safe parking host site violates Sec. 18.190.475(d)(12). Because the standard is a condition of the ministerial safe parking host site permit, code enforcement or the community development department can cite the site operator, and a pattern of violations can be grounds for the zoning administrator to deny the annual permit renewal required under subsection (c)(5).

Frequently Asked Questions

Can a generator run at a Fremont safe parking site during the day?
The ordinance only bars generators during quiet hours, defined as 10:00 p.m. to 7:00 a.m. under Sec. 18.190.475(d)(12). Outside that window the section does not impose a generator-specific restriction, though the site's approved operations plan and other nuisance rules can still apply.
Who enforces the generator quiet-hours rule at safe parking sites in Fremont?
The community development department oversees the safe parking host site permit process, and the zoning administrator or designee issues and renews the permit under Sec. 18.190.475(c). A documented breach of the quiet-hours standard in (d)(12) can factor into permit renewal review.
Does the quiet-hours rule apply to all vehicles at the site or just RVs?
The text applies the 10:00 p.m. to 7:00 a.m. quiet hours and generator ban to the safe parking host site as a whole, not to a specific vehicle type, distinguishing it from the vehicle clearance rules in (d)(7) that do set different distances for cars/vans versus RVs.
