Conditions for Job Sites

Building in Existing Neighborhoods

About 7.4% of Birmingham'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 Birmingham'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 detached houses, about 58% of units (lower than most U.S. places in our data), followed by buildings with five or more units at about 33% (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. About 55% 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 Jefferson County in the Mixed-Humid climate region (IECC 2021 zone 3A, 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.

Heat

About 65 days a year reach 90°F or more, more than three in four U.S. places in our data, most of them in the summer months. For long rentals in the hot, humid months, ask how often units will be serviced. Ask whether the service schedule changes in the summer months, when crews use units more.

Freezing Nights

About 47 nights a year reach 32°F or below, fewer than most U.S. places in our data, mostly between late fall and early spring. Freezing nights are routine in winter; ask whether the provider changes its service approach for winter job sites. Snow is light, about 1 inches in an average year.

Lead-Safe Renovation

About 72% 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 employeesMinimum toilet facilities
20 or fewer1 toilet
20 or more1 toilet seat and 1 urinal per 40 workers
200 or more1 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.

Rain and Ground

About 57 inches of precipitation falls in an average year, with about 18 days of an inch or more, in the top tenth of U.S. places in our data. On muddy job sites, put units on gravel or a firm pad near the site entrance so the service truck does not get stuck, and move them if the ground around them washes out.

Federal OSHA or State Plan

Alabama is not an OSHA-approved State Plan state: federal OSHA covers most private-sector workers there (osha.gov State Plans, accessed 2026-10-13), so 29 CFR 1926.51 is the toilet rule for private job sites. State and local government workers are not covered by federal OSHA.

Who to Ask About Local Rules

Birmingham 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 Birmingham 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
  • Winter servicing and freeze protection for holding tanks
  • Summer service frequency
  • A gravel pad near the site entrance
