Which OSHA rule covers porta potties on Texas job sites?
Texas private job sites follow federal OSHA because Texas has no state OSHA plan for private employers. Construction crews fall under 29 CFR 1926.51. Plants and yards fall under 29 CFR 1910.141. Farms with field crews fall under 29 CFR 1928.110. Each of the 3 rules sets a different toilet ratio.
Pick the rule by the type of work, not the type of company. A pipeline crew building a new line is construction work. A crew running a finished compressor station day to day is closer to general industry.
How many toilets does OSHA require for a construction crew?
OSHA Table D-1 requires 1 toilet for 20 or fewer workers. A crew of more than 20 needs 1 toilet seat and 1 urinal per 40 workers. A crew of 200 or more needs 1 toilet seat and 1 urinal per 50 workers. A standard porta potty has both a seat and a urinal inside.
| Number of workers | OSHA minimum (29 CFR 1926.51 Table D-1) | Our comfort suggestion with weekly service |
|---|---|---|
| 1–10 | 1 toilet | 1 unit |
| 11–20 | 1 toilet | 2 units, or 1 unit with twice-weekly service |
| 21–40 | 1 seat + 1 urinal per 40 workers | 1 unit per 10 workers (3–4 units) |
| 41–80 | 1 seat + 1 urinal per 40 workers | 1 unit per 10 workers (5–8 units) |
| 200+ | 1 seat + 1 urinal per 50 workers | Call for a site plan |
Read the full text on the OSHA 1926.51 sanitation page. The rule also has an exception for mobile crews with ready transportation to nearby toilets.
Why do we suggest more units than the OSHA minimum?
The OSHA minimum lets 20 workers share 1 toilet. A standard unit is rated by its manufacturer for about 200 uses between services. Twenty workers on a 40-hour week can pass 200 uses in 2 or 3 days. Our 1-per-10 suggestion keeps a weekly-serviced unit usable all week.
That gap is where complaints start. A full tank by Wednesday means a crew walking off site or a foreman calling for an extra visit at $65 per unit.

Does OSHA require handwashing stations on Texas job sites?
OSHA 1926.51(f) requires washing facilities near the work when crews handle paints, coatings, herbicides, insecticides or other harmful contaminants. The facilities need water, soap and towels. A 2-sink handwash station holds about 36 gallons and serves about 400 hand washes per fill. Hand sanitizer alone does not remove grease.
Many general contractors ask for 1 station per site even when the rule does not strictly apply. A hand-washing station rental needs no water hookup or power.
In freezing weeks, station water can freeze below 28°F overnight. We may swap the station for sanitizer dispensers during those nights.
What are the OSHA rules for yards, plants and farms?
Yards and plants follow 29 CFR 1910.141, the general industry rule, which sets its own toilet table by headcount. Farms follow 29 CFR 1928.110. That farm rule calls for 1 toilet and 1 handwashing facility per 20 workers, within a quarter-mile walk. The farm rule applies when 11 or more hand laborers work.
Yards and plants
See the OSHA 1910.141 rule. Oilfield service yards along I-20 and the east side often fall here.
Farms and ranches
See the OSHA 1928.110 field sanitation rule. The quarter-mile limit matters on wide fields.
For lease and plant work, our oilfield and industrial portable restrooms page covers pads, frac spreads and pipeline crews.
Do I need a wheelchair-accessible unit on a job site?
OSHA's construction toilet table does not require an accessible unit. An owner, fire marshal or public project may still ask for 1. A wheelchair-accessible unit is about 62 inches wide with a 60-inch turning space inside. A wheelchair-accessible unit starts at $215 pre-tax per 28-day cycle with weekly service.
The unit has no sink inside, so pair it with a handwash station. See the wheelchair-accessible porta potty for size and door details.
How often should a job-site porta potty be serviced?
Our 28-day rentals include 1 service visit every week. Each visit pumps the tank, scrubs and sanitizes, adds deodorizer, and restocks 2 or more toilet-paper rolls and sanitizer. The tech leaves a dated tag on the door. Twice-weekly service adds $60 per cycle per unit.
That dated tag helps when a safety manager walks the site. It shows the last service date at a glance.
A standard unit starts at $155 pre-tax per 28-day cycle. Contractors can apply for Net-30 invoicing. Read how billing and extensions work on our monthly porta potty rental page.

More questions about OSHA Porta Potty Requirements for Texas Job Sites
Does Texas have its own OSHA toilet rules?
No. Texas does not run its own state OSHA plan for private employers. Private job sites in Texas fall under federal OSHA. That means the federal ratios in 29 CFR 1926.51 apply to construction crews. Cities or owners can ask for more. Confirm with your permit office, venue or safety manager — this is not legal advice.
My crew is 8 people. Is 1 porta potty enough under OSHA?
Under OSHA Table D-1, 20 or fewer workers need at least 1 toilet. So 1 unit meets the legal minimum for 8 people. For comfort with weekly service, we suggest 1 unit per 10 workers on a 40-hour week. An 8-person crew fits that with 1 standard unit.
Do men and women need separate toilets on a job site?
OSHA's construction rule counts toilets per worker, not by gender. Toilets with locking doors that one person uses at a time can serve everyone. A standard porta potty has an occupied latch, and we add a free combination lock on request. Check your site's own policy too.
Does OSHA say how often a job-site toilet must be cleaned?
OSHA requires that toilets be kept sanitary but does not name a fixed number of visits. Our 28-day rentals include weekly service as standard. For crews of 10 or more in summer, we recommend twice-weekly service for +$60 per cycle per unit. Extra single visits are $65 per unit.
Is a hand sanitizer dispenser enough for handwashing?
It depends on the work. OSHA 1926.51(f) calls for washing facilities near the work for crews handling paints, coatings, herbicides, insecticides or other harmful contaminants. Sanitizer does not remove grease or chemicals. A 2-sink handwash station holds about 36 gallons and serves about 400 washes per fill.
Can the fire marshal or owner require more than OSHA?
Yes. OSHA sets a floor, not a ceiling. A general contractor, owner, or local official can require more units, an accessible unit, or more service. Ask for the site rules in writing. We can add a wheelchair-accessible unit to an open rental when a request comes in.
