Weather and Building Across the State

Heat

Indio, Coachella, La Quinta and 3 other listed places share the most hot days of all 544 California places listed here: about 187 days a year at or above 90°F (NOAA normals, Desert Resorts Regional Airport, CA station). 224 of 544 listed places reach 90°F on 60 or more days a year, and 200 average 10 or more days at 100°F. For most of the state, heat is a summer-month issue rather than a constant one.

Freezing Nights and Snow

South Lake Tahoe has the most freezing nights of all 544 California places listed here: about 222 nights a year at or below 32°F (NOAA normals, South Lake Tahoe Airport, CA station). 8 of 544 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. Pollock Pines has the most snowfall of the 60 listed California places with this figure: about 58 inches of snow a year (NOAA normals, Pacific House, CA station). 1 of 60 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.

Rain

El Centro, Calexico, Brawley and 4 other listed places share the least precipitation of all 544 California places listed here: about 2 inches of precipitation a year (NOAA normals, Imperial Co. Airport, CA station). 333 of 544 listed places get under 15 inches a year: firm, dry ground, but wind and dust on open sites, so ask for units to be staked.

New and Older Housing

Rancho Mission Viejo has the highest share of recent housing of the 462 listed California places with this figure: 95.1% of housing units built in 2010 or later (ACS 2020–2024). 69 of 462 listed places are above the U.S. share of 11.4%. That describes the housing stock, not current permits, but it shows where new-home construction has been concentrated; OSHA's toilet table applies to every one of those job sites. Piedmont and Walnut Park share the oldest housing of the 543 listed California places with this figure: a median year built of 1939 or earlier (ACS 2020–2024). 191 of 543 listed places have a median year built of 1970 or earlier, where renovation crews in existing buildings are the usual job site.

Climate Regions

Listed places by DOE Building America climate region (county-level, PNNL guide to IECC 2021 zones): Hot-Dry (382), Marine (145), Mixed-Dry (10), Cold (7). A state spanning several regions means the right advice depends on the city, which is why each city page has its own figures.

Shoreline Places

58 of 544 listed places have a Census reference point within 5 km (about 3 miles) of the shoreline in the TIGER coastline layer, which includes Great Lakes shores. Beach and waterfront sites need a firm approach for trucks and a firm route for ADA units.

Job-Site Toilet Rules: Federal OSHA or State Plan

California runs an OSHA-approved State Plan, Cal/OSHA (Division of Occupational Safety and Health), California Department of Industrial Relations, that covers most private-sector workers as well as state and local government workers (osha.gov State Plans, accessed 2026-10-13). State Plans must be at least as effective as federal OSHA, so check the State Plan's construction sanitation rule alongside 29 CFR 1926.51. osha.gov lists some coverage exclusions for this plan; the State Plan page shows which work they affect.

The federal minimum, OSHA 29 CFR 1926.51(c), is one toilet for 20 or fewer workers, then one toilet seat and one urinal per 40 workers, or per 50 at 200 or more. Sizing details: construction rentals in California.

Who Handles Event and Street-Use Rules

Of the 544 California places listed here, 351 are incorporated cities, towns, villages or boroughs and 193 are Census-designated places, unincorporated communities without a municipal government. The rule of thumb for an event on public land or a unit on a street or sidewalk: in an incorporated place, ask the city, town, village or borough government; in an unincorporated community, ask the county. We do not say whether a permit is needed; each city page names who to ask.

Questions About Renting in California

My town isn't listed. Can I still call?

Yes. 544 California places have their own page because they have published Census and NOAA figures, but we take calls for any address in California. Call (888) 417-6737, answered 24/7. Tell us the units you want; the provider confirms what's available for your site.

What weather matters most for rentals in California?

Dry, open ground: 333 of 544 listed places get under 15 inches a year, so ask for units to be staked on windy sites. (NOAA 1991–2020 normals.)

Does California use federal OSHA or a State Plan for job sites?

California runs an OSHA-approved State Plan, Cal/OSHA (Division of Occupational Safety and Health), California Department of Industrial Relations, that covers most private-sector workers as well as state and local government workers (osha.gov State Plans, accessed 2026-10-13). State Plans must be at least as effective as federal OSHA, so check the State Plan's construction sanitation rule alongside 29 CFR 1926.51. osha.gov lists some coverage exclusions for this plan; the State Plan page shows which work they affect.

What about sites near the California border?

Call the same number. Several listed California places have towns in Nevada, Oregon, Arizona among their nearest neighbours; we connect you with a provider that serves the site's actual address, in whichever state it is.

How many porta potties do I need?

For events, the PSAI chart sizes units by crowd and hours; for job sites, OSHA 1926.51 sets the minimum by headcount; and at least 5% of each cluster should be ADA-accessible.

Don't know where to start?

Call now and tell us about your event or job site. We will help you work out the units you need and connect you with a provider that serves your location.
