Whose work this is and who answers for it
Seattle Porta Potty Rental is a switchboard. It takes requests for portable toilets, accessible units and handwash sinks in the Seattle area and passes each one to an unaffiliated local outfit. It does not put units down, deliver, empty, clean, collect or haul them, and it does not carry any waste to a site. The local outfit that attends answers alone for its quotation, its equipment, the place it stands a unit and the quality of its work.
Washington's Department of Health regulates the people who pump and haul septage under WAC 246-272A, and Ecology regulates the facilities that accept it under WAC 173-308. Those responsibilities sit with the outfit that performs the work. This website holds no authorization, licence or permit and asserts none. Permits for City streets and Parks land are the responsibility of the event organizer, and the City offices that issue them decide them.
The outfit's authorization numbers are supplied by telephone on request, or when its crew rings ahead to confirm the visit, and they are not published here to protect the outfit's commercial details. Check any number with the Department of Health before the unit is set down, and take any question about loss or damage to your own insurer.

Prices are estimates
Price ranges are typical estimates for our service area in 2026. They are not quotes or offers. Your price is confirmed in person before any work starts.
Safety and sanitation
A portable restroom holds human waste and a deodorising chemical, and both should be treated as hazardous. Do not open, drain, tip or move a unit yourself, and do not put anything into it but what it is there for — rubbish, solvents, paint and hot ashes all cause problems that the next person to service it has to deal with. Keep children from playing in or around units, do not smoke inside one, and wash or sanitise your hands afterwards; that is what the hand-wash station beside the unit is for.
Placement is a safety matter too. A unit must stand on firm, level ground, clear of vehicle routes, doorways, fire exits, hydrants and overhead lines, and it must not block a footway or an accessible route. On soft ground, slopes, roof decks or in exposed wind it has to be anchored or ballasted, because an empty unit is light enough to go over. Tell us about slopes, soft ground, overhead cables, weight limits and gate widths before delivery rather than after.
In hot weather units need servicing more often; in freezing weather they need a winter additive and clear access for the service vehicle. If a unit is damaged, has been tipped over, or is overflowing, do not use it and do not try to right it — call us and we will deal with it.
Licensing, permits and waste disposal
Portable sanitation is not a licensed trade the way plumbing or electrical work is, and Washington issues no portable-restroom contractor licence. We do not claim one, and nothing on this Site should be read as a claim to hold a licence, certification or approval we do not have.
What is regulated is the waste and where it ends up. Sanitary waste taken out of a unit may only be discharged at a facility permitted to receive it — a wastewater treatment works or a permitted septage disposal site — and in most states the vehicles and operators that haul it are registered or permitted by the state environmental or public-health agency and have to keep records of what was collected and where it was discharged. The exact requirement differs by state, county and city; the one that applies to your job is the one in force where the unit stands. Ask us how your waste is handled and where it goes.
Where units are needed is set by other rules again. On construction sites, OSHA's sanitation standard (29 CFR 1926.51) sets how many toilets are required for the number of workers and requires them to be kept clean and serviced. Events open to the public come under the Americans with Disabilities Act, which is why wheelchair-accessible units are not an optional extra. A temporary event usually needs sign-off from the local health department, and a unit standing on a pavement, verge or street normally needs the landowner's permission and sometimes a right-of-way permit. We will tell you what we know about the requirements in your area, but confirming them for your site or event is the organiser's or the site manager's responsibility, and nothing here is legal or regulatory advice.
