How many porta potties do I need under OSHA rules?
OSHA 1926.51(c)(1) sets the baseline: 1 toilet facility for a crew of 20 or fewer. Once you cross 20 workers, the ratio shifts to 1 toilet seat and 1 urinal per 40 employees, and it steps down again to 1 per 50 once headcount hits 200 or more. A 15-person crew working a home renovation in Kendall needs just 1 unit. A 60-person crew building out a strip mall near Coral Gables, 7.9 miles east, needs 2. Run the math with our how many porta potties do I need guide before you order, because under-counting is the fastest way to fail an inspection. If you are staffing an agricultural crew instead, OSHA 1928.110 applies a different rule: 1 facility per 20 hand-labor workers, reachable within a quarter mile walk, which matters for farm sites outside the Kendall core. See our farm and agricultural restrooms page for that specific setup. Most Kendall job sites rent standard porta potty rental units to hit these numbers without overspending on features nobody needs on a framing crew.
What are the OSHA portable toilet distance requirements?
OSHA does not publish a fixed foot-and-inch distance rule for portable toilets on construction sites the way it does for agriculture. What it does require is that placement be practical: workers need reasonable access without long walks off task. Field sanitation under OSHA 1928.110 sets a quarter mile walking limit for agricultural hand-labor sites, which is the clearest distance number in the standard. For general construction, ANSI/PSAI Z4.3 sets the service interval instead of a distance: 1 cleaning visit per week covers up to 10 users over a 40 hour week. If your Kendall site runs multiple shifts or a bigger crew, you will need more frequent service or more units to keep pace. Our porta potty placement guide covers ground clearance, truck access and where not to put a unit near a dumpster pad or fence line. Placement also has to account for delivery: a roll-off truck needs about 60 feet of straight clearance behind it, which matters if toilets and a roll-off dumpster rental share the same staging area.
Does cal osha portable toilet requirements apply in Kendall?
No. Cal/OSHA is California's own state plan, and it does not apply to Kendall or anywhere else in Florida. Florida follows federal OSHA rules directly, so 1926.51(c)(1) is the standard that governs your Kendall job site, not the California version. Contractors who split work between states sometimes mix the two up, and the ratios are close enough to cause real confusion. If you are bidding jobs outside Florida, check the applicable state plan separately rather than assuming federal numbers carry over. For water access alongside toilets, OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, a separate requirement from toilet counts. Pair a handwashing station rental or a portable sink rental with your toilets to cover both rules at once. Note that 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at washing stations, hand sanitizer alone does not satisfy it, and that standard governs general industry workplaces rather than construction sites.
Are there ADA accessible unit requirements on Kendall job sites?
Yes, when units are clustered together. ADA Standards section 213.2 requires that at least 5 percent of clustered single-user portable toilets be accessible, and never fewer than 1 unit even on a small cluster. That accessible unit needs a 36 inch clear route under section 403.5.1, a 32 inch door opening under 404.2.3, and a 60 inch turning circle inside under 304.3.1. Most public-facing sites in Kendall, including events near Palmetto Bay, 5.6 miles southeast, need at least one ADA accessible porta potty on site regardless of total unit count. Ramp slope for any elevated unit cannot exceed 1:12 under section 405.2. If your crew is doing painting, coating or pesticide work, OSHA 1926.51(f)(1) kicks in a separate washing facility requirement specific to those contaminants, distinct from the general toilet count. Review ADA restroom requirements and OSHA portable toilet requirements together before finalizing your site plan, since they overlap but are not identical.

How many porta potties do I need for a 20-person crew?
One unit covers a crew of 20 or fewer under OSHA 1926.51(c)(1). Once you add a 21st worker, you need to move to the next tier, which requires 1 toilet seat and 1 urinal per 40 workers. Check our how many porta potties do I need page for crew-size math.
Do porta potties need to be serviced weekly?
ANSI/PSAI Z4.3 sets a weekly service baseline for up to 10 users over a 40 hour week. Busier Kendall sites or larger crews need more frequent visits to stay ahead of capacity. See how often are porta potties cleaned for service scheduling.
Is hand sanitizer enough to meet OSHA handwashing rules?
No. 29 CFR 1910.141(d)(2) requires soap plus towels or a hand-drying device, and sanitizer alone does not satisfy that standard. Pair your toilets with a proper handwashing station rental or hand sanitizer station rental as a supplement, not a replacement.
What size door does an ADA porta potty need?
ADA Standards section 404.2.3 requires a minimum 32 inch clear door opening on accessible units. The unit also needs a 36 inch clear approach route and a 60 inch turning circle inside. Order through ADA accessible porta potty for compliant units.
Can I rent a storage container alongside my porta potties?
Yes. Many Kendall job sites pair toilets with a storage container rental or a 20ft storage container for tools and materials on the same lot. Delivery logistics for both should be planned together, especially where truck clearance is tight.
