Restroom Trailer Site Requirements Checker
Failed deliveries are the quiet headache of trailer rentals: the truck shows up, the gate is 9 feet wide or the only power is an extension cord, and the event scrambles. Six quick questions test your site against the same checklist delivery crews use — surface, slope, access, clearance, power, and water.
Most 'failures' have standard fixes — leveling jacks, generators, water totes. The result is a delivery-ready site profile you can hand independent local rental providers so quotes come back accurate the first time.
How this works
The checklist mirrors the site requirements rental providers publish for delivery and setup: a firm surface (pavement, gravel, packed dirt, or firm grass) that holds the truck and the trailer's leveling jacks; ground level enough that jacks can correct it — roughly 6 inches of drop side-to-side and 12 inches front-to-back, about a 2–3° grade; 10–16 feet of access width with a ~60 ft turning radius for the truck-and-trailer combination; and 12 feet of overhead clearance along the entire delivery route, not just at the final spot.
Utilities follow the same published specs: power within 50 feet of the trailer — one to two dedicated 20-amp circuits for small trailers, 30–50 amp service for large ones, or a generator sized at 3,600W minimum to run a 30-amp trailer with air conditioning (6,000–12,000W for 50-amp units); and water from a standard spigot and garden hose, with 100–200 gallon onboard fresh tanks or delivered water totes covering dry sites. Each answer maps to pass, workable-with-fix, or a flag that needs a provider's judgment — the same triage a dispatcher runs on the phone.
This checker sizes stall counts separately — if you haven't picked a trailer yet, the size calculator applies the 1-stall-per-50-guests rule (and OSHA 1926.51 Table D-1 for job sites) first. A flagged site is not a dead end: alternate placement spots, smaller units, mats and cribbing, trimming, and generators solve most of them. Independent local rental providers make the final call with a route check — this tool just means you arrive at that conversation with answers instead of guesses.

Frequently Asked Questions
Can a restroom trailer fit in my backyard?
Often, yes — the deciding factors are the gate or side-yard width (10–12 ft minimum, 12 ft+ ideal), 12 ft of overhead clearance the whole way in, and roughly a 60 ft turning radius for the delivery truck. Measure the narrowest point of the path; that single number answers most backyard questions.
What power does a restroom trailer need?
Small trailers run on one or two dedicated 20-amp household circuits within 50 ft; large 6–10 stall units want 30–50 amp service. No power at the site just means renting a generator: 3,600W minimum runs a 30-amp trailer including AC, and 50-amp units want 6,000–12,000W.
What if my site has no water hookup?
Dry sites are routine. Trailers carry 100–200 gallon onboard fresh-water tanks, and providers deliver water totes for longer events. If you do have a spigot, a standard garden hose is all the connection a trailer needs.
How level does the ground need to be?
Trailers level on jacks, which correct roughly 6 inches of drop side-to-side and about 12 inches front-to-back — a 2–3° grade. Anything steeper needs a different spot on the property. Firm, dry ground matters as much as level ground: soft soil after rain is the most common setup problem.
