Tulsa Special Event Permit Restroom Rules: Ratios, Access, and Deadlines
A public event in Tulsa needs a restroom plan before the city signs off. The City of Tulsa Special Events Office reviews your toilet count, your accessible units, and where they sit on the site map. This guide covers the ratio, the accessibility rule, and the dates you need to hit.
How many portable toilets does a Tulsa special event permit require?
The City of Tulsa Special Events Office uses a standard of 2 portable toilets for every 250 people, based on estimated peak attendance. Portable restrooms are required unless enough accessible and standard restrooms are open to the public nearby during the event. Plan the count around your busiest hour, not the total gate count.
The table below applies the city guideline to common crowd sizes. The accessible column uses the 10% rule, with at least 1 accessible unit at every event.
| Peak attendance | Toilets (2 per 250) | Accessible units (10%, at least 1) |
|---|---|---|
250 | 2 | 1 |
500 | 4 | 1 |
1,000 | 8 | 1 |
1,500 | 12 | 2 |
2,500 | 20 | 2 |
5,000 | 40 | 4 |
Treat the city number as a floor. Our sizing method for short events is 1 standard unit per 50 guests for up to 4 hours. Longer events and events with alcohol need more, so run your numbers through the porta potty calculator for events before you file.
How many restrooms at a Tulsa event must be wheelchair accessible?
At least 10% of restroom facilities at a permitted Tulsa event must meet accessibility rules, with 1 or more accessible units at each location. That unit must sit on a level area with no more than a 2% cross-slope. An accessible route must also lead to each portable restroom.
Federal rules set a lower bar. The 2010 ADA Standards, section 213.2, call for at least 5% of clustered portable toilets to be accessible, per the U.S. Access Board guide to the 2010 ADA Standards.
The city's 10% rule is stricter, so follow the city number.
A typical wheelchair-accessible unit has about an 87 by 87 inch footprint and a ground-level floor with no step. Inside, it has a 60-inch turning space, grab bars, and a wide door. Plan about an 8-foot-wide flat path to each one, and see the wheelchair-accessible (ADA-style) porta potty page for specs.
When is a City of Tulsa special event permit application due?
The City of Tulsa deadline depends on what your event uses, and closures of a street, sidewalk, or parking space need 60 days. Public outdoor events with no closures need 40 days. Neighborhood block parties need 30 days, and tent permits need 15 days.
| Event type | Apply at least | Where it is filed |
|---|---|---|
Street, sidewalk, or parking space closure | 60 days before | Special Events Office (up to 1 year early) |
Public outdoor event, no closures | 40 days before | Special Events Office |
Neighborhood block party (one residential block) | 30 days before | Planning and Neighborhoods online application |
Tent permit | 15 days before | One-Stop-Permit Center |
Two other dates matter. Outdoor beer, wine, or liquor needs a state ABLE Public Event License filed 60 days out. The city also wants your certificate of insurance at least 15 business days before your first closure or venue date.
What should the restroom part of your event site plan show?
A good restroom site plan shows 4 things: each toilet cluster, the standard and accessible count in each, the hand-wash stations, and the accessible route. Mark the service truck path too. The truck must park on firm ground within about 50 feet of each unit.
- Keep each porta potty at least 10 feet from tents, grills, and doors of food areas.
- Pick level ground, and mark each spot with a flag, cone, or chalk.
- Leave a 48-inch-wide path for standard units and about 8 feet for accessible units.
- Add hand-wash stations when food is served: at least 1, and 1 per 100 guests.
Hand-wash stations hold about 20 gallons and give roughly 250 washes per fill. See hand-wash station rental for sizes, and event porta potty rental for delivery details.
How far ahead should you book porta potties for a permitted event?
Book restrooms 2 to 4 weeks before a permitted event when you need 5 or more units, a restroom trailer, or several accessible units. That timing lets you put confirmed numbers on the application. Cancellation is free until 2 p.m. the business day before delivery, and date changes are free when the new date is open.
Large events often need a mix of unit types. A restroom trailer can serve a VIP or sponsor area, while standard and accessible units handle the main crowd. Put the mix on the site plan so reviewers can see the total count.
For weekend events, units arrive Friday (or Thursday) and leave Monday at no extra cost. There are no Sunday deliveries or pickups. Orders of 5 or more units get $10 off each unit, and the full rate list is on the porta potty rental pricing page.

Quick answers
These 4 answers start with the question renters ask first here: do i need porta potties if my tulsa event site already has restrooms. Each answer gives the number or rule up front, then the conditions, so you can book without a second call.
Do I need porta potties if my Tulsa event site already has restrooms?
The City of Tulsa requires portable restrooms unless enough accessible and standard restrooms are open to the public nearby during the whole event. If the building closes early or has too few stalls for peak attendance, add portable toilets.
How does the 10% accessible rule round?
The city asks for at least 10% accessible, so round up. An event with 12 toilets needs 2 accessible units, because 1 unit is only 8%. Every event needs at least 1 accessible unit.
What is the City of Tulsa toilet ratio for events?
The Special Events Office uses 2 portable toilets for every 250 people at peak attendance. That is a minimum. Longer events and events with alcohol usually need more units.
