Porta Potty Rental in California, MD
California is an unincorporated community (a Census-designated place) in St. Mary's County, Maryland, and we take portable toilet rental calls for any address in it. Call (888) 417-6737, answered 24/7, and we connect you with a provider that serves the site. Rain is the main planning factor: about 45 inches a year (NOAA normals), so units need firm ground a truck can reach.

California at a Glance
Climate figures: NOAA 1991–2020 normals from the Patuxent River Nas, MD station, about 4 miles away.
Planning Around the Weather
DOE's Building America map puts St. Mary's County in the Mixed-Humid climate region (IECC 2021 zone 4A, PNNL county guide). This region gets both a real summer and a real winter, so a July rental and a January rental need different planning.
Rain and Ground
Heavy rain days are frequent: about 12 days a year bring an inch or more of precipitation, out of about 45 inches in total. Soft ground is the risk: units belong on a firm, level base the service truck can reach without crossing a soggy lawn, and an ADA unit needs a route that does not turn to mud.
Freezing Nights
About 68 nights a year reach 32°F or below, fewer than most U.S. places in our data, mostly between late fall and early spring. Water-carrying units need a plan from late fall into spring: give your dates when you call and ask how hand-wash water and flush tanks are kept from freezing.
Summer Hot Spells
About 26 days a year reach 90°F, fewer than most U.S. places in our data; hot spells come and go rather than lasting all summer. If your dates land in a hot spell, ask for an extra service visit on multi-day rentals and keep hand-wash stations topped up.
Job Sites and Home Projects
New Housing
About 17.9% of California's housing units were built in 2010 or later (ACS 2020–2024), above the U.S. share of 11.4% and higher than three in four U.S. places in our data: newer construction sits alongside older stock, so job sites range from new homes to additions and repairs.
Apartments, Townhouses and Rentals
The most common housing type is detached houses, about 68% of units (higher than most U.S. places in our data), followed by buildings with five or more units at about 16% (ACS 2020–2024). Detached houses usually have a driveway or yard where a crew's unit can stand within reach of the service truck. Apartment and condo projects bring larger crews, and a property manager decides where units go. Townhouses and rowhouses share walls and often lack a side yard, so a unit for a renovation may need to sit in a shared driveway or at the curb. About 37% of occupied homes are rented (owner share lower than most U.S. places in our data), so check who controls the property before a unit goes on it.
OSHA 29 CFR 1926.51 sets the floor: one toilet for up to 20 workers, then a seat and a urinal per 40 (per 50 at 200 or more). More on sizing: construction rentals in Maryland.
Events, Weddings and Parties
An all-day festival for 5,000 people over six hours needs 38 units on the PSAI event chart, or 42 to 46 with alcohol (PSAI adds 10–20%). Every cluster of restrooms needs at least 5% accessible units, rounded up, and with heavy rain this common the ADA unit needs a route that stays firm when the grass is wet.
Cold, not heat, limits the outdoor season: from late fall into spring, ask for a heated restroom trailer or units that do not depend on running water. Events in a county park follow the county parks office's rules; ask it what applies before you book. More: event rentals in Maryland and wedding restrooms in Maryland.
Who to Ask About Local Rules
California is unincorporated (a Census-designated place), so St. Mary's County, not a city hall, handles local roads, parks and events. For an event on public land, or a unit that will stand on a street, sidewalk or in a park, ask the St. Mary's County government before you book what applies.
On attached or small multi-unit lots without a driveway, a unit at the curb is a street-use question for the St. Mary's County government.

I rent my home in California. Can I order a porta potty?

Who do I ask about a permit for an event or a unit on the street in California?
Ask the St. Mary's County government. There is no city hall; the county handles local roads, parks and events.
