A single hand-labor crew of 20 or fewer field workers needs at least one toilet and one handwashing setup within a quarter mile walk, per OSHA 1928.110. Southfield Porta Pros sets up standard units and handwashing stations for farms, produce stands and seasonal operations, with delivery scheduled around planting and harvest windows.
OSHA 1928.110 covers hand-labor operations in agriculture and it is specific: potable water, toilets, and handwashing facilities, provided at a rate of one facility per 20 employees, and located within a quarter mile of wherever the crew is actually working. That is different from the construction standard, OSHA 1926.51(c), which covers job sites, not fields. If your operation runs both a construction crew and field labor on the same property, you likely need both types covered separately. Southfield Porta Pros places standard portable toilets at the edge of active rows so workers are not walking a half mile back to a barn. Water has to be potable under OSHA 1926.51(a)(1), and handwashing has to include soap and a way to dry hands, not just sanitizer, per 29 CFR 1910.141(d)(2). We pair each toilet with a handwashing station or a portable sink so that requirement is met without guesswork. For operations near Southfield running seasonal crews, we also serve growers out toward Redford, about 7.6 miles south, and Bloomfield, 8.9 miles north, on the same delivery route.
Run the math off crew size, not acreage. A 15-person picking crew needs one unit under the 1928.110 ratio. A 40-person crew needs two. Fields spread across multiple parcels change the count fast, because the quarter mile walk limit applies to each work location, not the property as a whole. Use our guide on how many porta potties you need to work through your specific layout, or just call and describe the acreage and crew count. A standard unit holds a 60 to 70 gallon tank and stands about 92 inches tall, footprint of roughly 44 by 48 inches, small enough to sit at a field edge without eating into planted rows. Weekly rentals run $130 to $500 depending on unit count and service frequency, and monthly terms land between $125 and $325 per unit; check monthly porta potty rental for the specifics. Delivery itself carries a separate fee, typically $50 to $150 for a weekly setup. If your labor crew includes anyone applying pesticides or herbicides, OSHA 1926.51(f)(1) kicks in on top of the general field sanitation rule, and that means washing facilities at the point of exposure, not just back at the barn.
Yes, and that is the actual problem farms run into: a unit that is fine in week one but never gets serviced again by week four. ANSI/PSAI Z4.3 sets the baseline service interval at once a week for up to 10 users across a 40 hour week, and a full harvest crew working longer days can push past that fast. We build a route around your harvest schedule instead of a fixed calendar date, so service happens when the crew count says it should, not on a day that made sense in a spreadsheet. That matters most for larger operations near Southfield running multiple fields at once, where a truck has to actually reach each unit. If you are near West Bloomfield, about 11.7 miles northwest, or Oak Park, 4.9 miles east, we route those stops on the same day to keep service tight. For farms that also need waste hauled off site, look at roll-off dumpster rental for packaging and crop debris, and if you run a wash station or processing shed with grease in the drain, grease trap pumping covers that separately from field sanitation. Septic tanks serving a farmhouse or bunkhouse typically need pumping every 3 to 5 years depending on tank size and household count; see septic pumping service or how often to pump a septic tank if that is overdue.
For operations with a bunkhouse or on-site crew housing, an ADA accessible unit may apply if the housing serves the public or falls under separate accessibility rules; ADA Standards 213.2 requires at least one accessible unit in any cluster, minimum 5 percent. Southfield Porta Pros can also bring in a restroom trailer for larger seasonal crews or a u-pick event drawing outside visitors, and a handwashing requirements page walks through what applies where. Full construction site services are available if you are building new structures on the property at the same time as running the farm.
A standard unit runs $130 to $500 a week depending on service frequency and unit count, or $125 to $325 a month for longer seasonal placement. Delivery adds $50 to $150 for weekly terms. See porta potty rental cost for the full breakdown by duration.
Placement rules can depend on where the unit sits relative to a road or public right of way, and that needs confirming with the city rather than assumed. Check porta potty permit requirements before delivery day, especially near shared field access roads.
Units stay in place through rain and mud as long as the ground under them is stable. Winter operations have separate concerns, covered in porta potty in winter, including freeze protection for the tank and hand sanitizer stations.
No, not under the 1928.110 quarter mile rule. Each work location needs its own facility within that walking distance, which usually means multiple smaller placements instead of one central unit for a large farm.
ANSI/PSAI Z4.3 sets a weekly baseline for up to 10 users, but a full harvest crew often needs twice-weekly service. See how often are porta potties cleaned for how that scales with crew size.
Yes. Southfield Porta Pros delivers farm and agricultural restrooms across Southfield and the surrounding metro, with same-day and next-day drop-off available on most orders.
Pricing depends on the unit and how long you need it. See our cost breakdown and request a free quote for an exact figure.
Standard rentals include scheduled service — a pump-out, a clean, a restock and fresh deodorizer. Busy or hot-weather sites can be serviced more often.
