Temporary restrooms and showers for California
This California carries its name from before 1897, possibly from a farmstead built with materials from the Golden State, though the origin is uncertain. It sits where Route 4 crosses Route 235, called Three Notch Road and lined with department stores and shopping centers, and it grew outward from neighboring Lexington Park. Naval Air Station Patuxent River anchors the local economy, and the narrow Governor Thomas Johnson Bridge leads to the resort town of Solomons. California is unincorporated, governed by St. Mary's County.
A shower trailer rental here means private stalls with hot water; a restroom trailer rental means flush toilets and sinks. Combination trailers put all three in each stall, with an ADA stall when you need one.

Local requirements to check in California
California is unincorporated, so St. Mary's County governs it, not a town. The county's Department of Land Use and Growth Management handles permits, and its Permits Division covers building permits. The county Health Department's Environmental Health office handles inspections and permits for matters such as sanitation. No published St. Mary's County rule on temporary restroom or shower trailers was found, so call Land Use and Growth Management and ask whether the Health Department must sign off.
- Leonardtown is the county seat, with Land Use and Growth Management permitting based there.
- Land Use and Growth Management runs permits; the Health Department runs environmental health.
- Navy base events fall under the base, not the county.
Keep trailer routing off Route 235 and the bridge during rush hour, and ask Land Use and Growth Management early whether a temporary use needs approval.

How California uses shower and restroom trailers
Air show and base events
The Pax River Air Show draws large crowds to the naval air station for free, with ID checks for adults. Events on base are organized by the Navy, so any trailer there would be arranged through that organizer.
Defense-sector project crews
With the naval air station and defense contractors driving local jobs, long-running building and site work nearby needs steady sanitation for crews.
Route 235 retail events
Shopping centers along Three Notch Road host sales and tent events in large parking lots, where added restrooms may be needed away from store buildings.
Getting a trailer across the Patuxent
Traffic around California is shaped by two routes and a bridge. Routes 4 and 235 cross here, and the Governor Thomas Johnson Bridge toward Solomons is narrow and known for backing up in rush hour. Weekend traffic to Solomons adds to the load. A delivery or pickup to this side of the river is easier outside commuter windows, and the bridge's narrowness is worth raising with whoever schedules transport for any site that involves crossing it.

Questions people ask before renting in California
Who do We contact about a restroom trailer for an event at a Route 235 shopping center?
California has no town government, so the question goes to St. Mary's County. Start with Land Use and Growth Management for temporary use rules and ask whether the Health Department must approve the sanitation setup. No published trailer-specific rule was found.
Can We bring a shower trailer to the Pax River Air Show?
The show is held on the naval air station, and access and vendors are controlled by the Navy. Any trailer would need to go through the show organizers, not the county. Nothing published about outside trailers at the show was found.
How much is a shower trailer rental near California?
Combination trailers start at $2,995 for 1 to 6 days, and the 20 ft shower container starts at $3,995. Delivery to California and servicing are quoted for your address.
Can I rent a restroom trailer in California for a wedding or event?
Yes. Short-term rentals cover weddings, festivals and private events, and luxury combination trailers give each guest a private stall. Share the date and guest count and we recommend a size.
