Where to Place a Porta Potty: Level Ground, Truck Access and Permits

By Mike, owner. Published October 20, 2026, 5-minute read

Where will it go? That is the first question to answer, and the one most people leave until delivery day. The right spot keeps the unit level, easy to service and out of the way.

This guide covers sizes, ground, truck access, spacing and the right-of-way rules in Bellingham.

How big is a standard porta potty?

A standard porta potty is about 43.5 inches wide and close to 4 feet deep. A common model, the PolyJohn PJN3, stands about 91 inches tall and 47 inches deep. In Bellingham yards and job sites, plan a clear pad about 5 by 5 feet with open space in front for the door.

Those numbers help you check a side yard, a gap between buildings or a spot under a carport.

Add room for the door to swing open and for a person to step in. ADA wheelchair-accessible units, deluxe units and restroom trailers are larger, so ask for their sizes before you pick a spot.

Will a porta potty fit through my gate?

A standard porta potty is about 43.5 inches wide, so a backyard gate in Bellingham needs at least 4 feet of clear opening, plus room to tilt it onto a dolly. Measure post to post, not the gate panel. Narrow gates, steps and steep paths often mean the unit stays in the driveway or front yard.

Units usually come off the truck and move on a dolly or hand truck. Every step, turn and soft patch between the truck and the spot makes delivery harder.

• Measure the narrowest point on the path, including the gate.
• Note any steps, slopes or tight corners.
• Check for low eaves or branches. The unit is over 7 feet tall.

Send a photo of the path and gate when you book. It saves a lot of guessing on delivery day.

Can the truck drive across grass to reach the spot?

A delivery truck can sometimes drive across firm, dry grass, but soft lawn in Bellingham's wet months can rut or trap it. Service trucks also need to return weekly on long rentals. Choose a spot on or near a hard surface, such as a driveway, gravel pad or parking area, whenever you can.

Delivery is one trip. Service is a repeat trip, often weekly, with a heavy truck that carries a waste tank and fresh water.

• The truck must get close enough for the pump hose to reach the unit. Hose reach varies by truck, so ask us before you pick a far corner.
• Leave a clear lane with no parked cars, materials or locked gates on service day.
• On farms and rural lots in Whatcom and Skagit counties, tell us about soft field roads, culverts or weight-limited bridges.

How far should a porta potty be from doors, food and neighbors?

Place a porta potty far enough from food, doors and windows that smell and lines don't bother anyone, but close enough that people use it. For Bellingham events, set it away from food service and downwind if you can. On job sites, Washington rules require toilets within 200 feet of all workers.

Good spacing is a balance. Too close and people smell it. Too far and people go elsewhere.

• Food: Keep units away from food prep, buffets and serving lines. Put a hand washing station between the toilets and the food.
• Doors and windows: Avoid placing a unit right under a bedroom window or next to a neighbor's patio.
• Job sites: WAC 296-155-140 says toilets must be within 200 feet horizontally of all employees.
• Night use: Choose a lit spot with a clear path.

What ground does a porta potty need: level, slope or overhead wires?

A porta potty needs level, firm ground so it does not lean, rock or tip. Avoid slopes, soft lawn, ditches and the bottom of hills in Bellingham's rainy season. Also look up. Keep the spot clear of overhead power lines, low branches and eaves so the truck can lift and set the unit safely.

• Level: A slight slope can be shimmed. A steep one can't. Pick the flattest spot.
• Firm: Gravel, asphalt and concrete are best. Wet lawn sinks.
• Drainage: Stay off low spots that pond after rain.
• Overhead: Note any wires, branches, carports or eaves above the spot and the truck path.
• Wind: On open sites, plan to stake or strap the unit.

Restroom trailers need level ground even more, since they sit on wheels and jacks.

Do I need a permit to put a porta potty on a Bellingham street or sidewalk?

A porta potty on private property in Bellingham usually needs no city permit. Placing one on a street, sidewalk, parking strip or other public right-of-way is different. Bellingham Public Works issues Temporary Right-of-Way Use Permits for items in the public right-of-way. Confirm with the Permit Center before you place anything there.

The City of Bellingham's Temporary Right-of-Way Use guide covers closing streets or sidewalks next to a job site, dumpsters, scaffolding and equipment. Items placed in the right-of-way must appear on your site plan, and reflective cones or barricades are required around large items there.

• Contact Public Works permitting at pwpermits@cob.org or 360-778-8329.
• Temporary no-parking signs must be posted 24 hours before a closure.
• Outside city limits, county roads and state highways have their own permit offices.

This is general information, not legal advice. Always confirm with the permit office.
