Conditions for Job Sites

Building in Existing Neighborhoods

About 7.8% of Los Angeles's housing units were built in 2010 or later (ACS 2020–2024), below the U.S. share of 11.4%, though above the median U.S. place in our data, so most homes predate 2010 and many projects are renovations or additions to existing buildings.

Older Homes and Remodels

The median year built for Los Angeles's housing is 1965 (ACS 2020–2024), older than three in four U.S. places in our data. Houses built around 1965 are now more than half a century old; kitchen, bath and roof jobs on them are construction work under OSHA 1926.51, and if the crew cannot use the home's bathroom, the rule calls for a toilet on site.

Apartments, Townhouses and Rentals

The most common housing type is buildings with five or more units, about 48% of units (higher than nine in ten U.S. places in our data), followed by detached houses at about 36% (ACS 2020–2024). Apartment and condo projects bring larger crews, and a property manager decides where units go. About 64% of occupied homes are renter-occupied (ACS; owner share lower than nine in ten U.S. places in our data), so property managers and landlords often book the units for renovations and decide where they stand.

DOE's Building America map puts Los Angeles County in the Hot-Dry climate region (IECC 2021 zone 3B, PNNL county guide). This region combines hot summers with low humidity: sun, dust and water supply are the usual planning issues, more than rain.

Weather is rarely the limiting factor on job sites here; crew size and site access drive the order.

Lead-Safe Renovation

About 70% of housing units predate 1980 (ACS 2020–2024). Under OSHA’s lead standard (29 CFR 1926.62), workers exposed to lead need adequate hand-washing facilities, and EPA’s RRP Rule covers paint-disturbing work in homes built before 1978; add hand-wash stations to the order on those jobs.

How Many Toilets

OSHA 29 CFR 1926.51(c)(1) sets the minimum number of toilets on a construction site by headcount:

Number of employees	Minimum toilet facilities
20 or fewer	1 toilet
20 or more	1 toilet seat and 1 urinal per 40 workers
200 or more	1 toilet seat and 1 urinal per 50 workers

Worked examples, rounding up as the table is usually read: 15 workers need 1 toilet. 45 workers need 2 toilet seats and 2 urinals (45 ÷ 40 = 1.125, rounded up to 2). 210 workers need 5 seats and 5 urinals (210 ÷ 50 = 4.2, rounded up to 5).

With so much multifamily housing here, a 45-person crew on an apartment or condo project is a realistic case: 2 toilet seats and 2 urinals.

Servicing frequency is set with the provider when you book; tell us headcount and shift length. OSHA's job-site toilet table has the full table.

Placement and Access

Put units on firm, level ground the service truck can reach, close to where crews work, clear of crane swing, excavation and vehicle routes, and move them as the work moves.

Dry, Windy Sites

Only about 13 inches of precipitation falls in an average year, in the driest tenth of U.S. places in our data. Stake units on open lots or set them against a structure, and keep them away from dust thrown up by grading.

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.

Who to Ask About Local Rules

Los Angeles is an incorporated city with its own municipal government. For a unit placed in the street, on a sidewalk or in another public right-of-way next to the job site, ask the Los Angeles city government before you book what applies.

If you rent your home, check with the landlord or property manager before a unit goes on the property.

What to Ask For

Crew size at the busiest point and shift length (OSHA sets the minimum by headcount)
Rental term and service frequency
A spot on site the service truck can reach
Whether units need to move as the work progresses
