How do I rent a porta potty in Fairfax, VA?
Dial 1-833-520-0680 and say whether it is a Fairfax job site or an event, plus the number of people and the dates. A local Fairfax (city) provider then confirms how many units you need, how often they will be serviced and the full price.

Job sites follow OSHA. OSHA 29 CFR 1926.51 requires 1 unit for up to 20 workers, then 1 toilet seat and 1 urinal per 40 workers from 20 to 199 workers, and 1 per 50 workers at 200 or more. Hand washing has to be available where the work involves contaminants.
Event ratios assume a crowd that flows. If your Fairfax event has a defined break where everyone moves at once, round the count up, because the ratio describes the average rather than the peak.
Heavy use and heat both shorten the interval. A Fairfax site that is comfortable on weekly service in spring often needs twice weekly through the hottest months.
What do Fairfax organisers need to know?
On public facing Fairfax events, put at least one ADA accessible unit on a level, firm route from the main area. Accessible does not help if the path to it is gravel or grass.
Keep about 5 by 5 feet clear per unit and leave the approach for the service truck open. Both matter for the whole rental rather than just the delivery day.
If the public can attend your Fairfax event, the accessible route matters as much as the accessible unit. A compliant unit at the end of a gravel path is not usable.
Signage helps at the margins on a large Fairfax site, but it does not fix an under count. If the queue is long, people look for alternatives regardless of the signs.

Fairfax porta potty questions
Do restroom trailers need power and water?
Most do. Trailers typically need a standard power connection and either a water hookup or an onboard fresh water tank, and they need level ground to sit on.
Are urinal only units available?
Yes, and on large male heavy crowds they can cut queues significantly for less than the cost of additional full units. Ask the provider about the mix.
How far in advance should I book?
Two to four weeks is comfortable for most events. Peak wedding and festival weekends in Fairfax (city) go much earlier, so book as soon as the date is fixed.
How often will the unit be serviced in Fairfax?
Weekly is the standard on job sites. In summer heat, or with more than about 10 workers per unit, twice weekly keeps the unit usable.
Can I rent a unit for a whole year in Fairfax?
Yes. Long term rentals are standard on construction projects and are usually billed monthly with weekly service included.
