What Does OSHA Require for Farm Sanitation?
Field sanitation for hand-labor agriculture falls under OSHA 1928.110, which calls for potable water, toilets and handwashing within a quarter mile walk of where employees work, at a ratio of one facility per 20 employees. That is different from a construction job, which runs on OSHA 1926.51(c)(1): one toilet for crews of 20 or fewer, then one toilet seat and one urinal per 40 workers once you pass that number. A lot of Gresham operations run both a field crew and a packing or storage crew, so the ratio that applies depends on which task the workers are doing. Gresham Porta Pros can walk you through how many porta potties do I need for a mixed crew, and set units at the field edge or near a barn depending on where the labor actually happens. If any part of the operation applies paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in separately and requires washing facilities for that contaminant exposure, on top of the general field sanitation rule. We pair handwashing station rental with toilet placement so both requirements are covered in one visit, and we can add a portable sink rental unit where soap and water need to sit closer to a packing line.

How Often Do Farm Restrooms Get Serviced?
A single standard porta potty rental holds 60 to 70 gallons and services on a weekly cadence under the baseline interval in ANSI/PSAI Z4.3, built around 10 users over a 40 hour week. Harvest crews and seasonal labor push past that fast, so most farms around Gresham move to two visits a week during peak season, or add a second unit rather than stretch the interval. We schedule around irrigation days and equipment movement, not just a fixed calendar, because a truck can't always reach a unit parked between rows during a spray window. If your property also runs a farmhouse or bunkhouse with a septic system, that is a separate question from field units. A residential tank is typically pumped every 3 to 5 years depending on tank size and household count, and septic pumping service or how often to pump a septic tank covers that side of things. Farms with a packing shed generating fryer or wash-down waste sometimes need grease trap pumping too; a grease interceptor gets pumped once fats, oils, grease and solids reach 25 percent of the liquid depth, not on a fixed schedule.

Where Should Units Go on Farm Property?
Placement on farmland is different from a job site. You want firm, level ground the service truck can reach without crossing planted rows, and a spot workers can walk to without cutting through active spray zones. ADA Standards section 302.1 calls for stable, firm, slip-resistant ground at any accessible unit, which matters if you have workers using a wheelchair or a walker on packing line duty. Our porta potty placement guide covers footing and truck access in more depth. Gresham properties often have long gravel access roads, so we confirm clearance before delivery day rather than guessing. Farms closer to Troutdale, about 4.7 miles northeast of Gresham, sometimes share equipment and labor crews with Gresham operations during harvest, and we route service trucks to cover both properties on the same day when schedules line up. If your farm sits toward Happy Valley, roughly 8.1 miles southwest, that is still inside our regular route. For remote fields with no road access at all, we talk through options on the service areas page before quoting anything.
| unit | duration | typical price |
|---|---|---|
| standard | day | $150 |
| standard | week | $200 |
| standard | month | $200 |
A day rate makes sense for a short pruning job. A week or month rate fits harvest season or a standing labor crew, and monthly porta potty rental pricing holds steady whether the unit sits at a vineyard or a construction trailer. See porta potty rental cost for how delivery and service fees stack on top of the unit rate.
Frequently asked questions
How many toilets does a 15 person harvest crew need?
Under OSHA 1928.110, one facility per 20 workers covers a 15 person crew with a single unit, as long as it sits within a quarter mile walk of the field. Add a second unit if the crew splits across two fields at once.
Can porta potties sit on unpaved farm ground?
Yes, as long as the ground is level and firm enough for the service truck and for workers to stand on safely. Gravel pads work well. Soft mud after rain can delay a pump-out truck, so tell us about drainage before delivery.
Do farm restrooms need to be ADA accessible?
If farm workers include anyone using a mobility device, ADA Standards section 213.2 requires at least one accessible unit in a cluster, never fewer than one. Our ADA accessible porta potty page covers the clear width and turning space that unit needs.
What is the difference between field sanitation rules and construction rules?
OSHA 1928.110 governs hand-labor agriculture and sets a quarter mile walk limit. OSHA 1926.51(c)(1) governs construction sites and scales differently by crew size. A farm running both field labor and a building project may need to satisfy both rules at once.
Can Gresham Porta Pros service remote fields without paved roads?
Usually yes. We check gravel and dirt road access before delivery and route around planted rows. Some far-out parcels near Camas, about 20.4 miles north of Gresham, still fall inside our standard service radius.
