Do you need a permit for a porta potty in Florissant?
A porta potty on your own driveway or yard usually needs no permit. Street, sidewalk and park placement does. Here is who to call in Florissant, St. Louis County, the City of St. Louis and on state roads, plus how to pick the right spot.

When does a porta potty need a permit in Florissant?
A porta potty on private property, such as your driveway or yard, needs no permit in most cases. A unit on a public street, sidewalk, alley or in a city park needs approval from the City of Florissant first. Block parties need a block party permit from the Mayor’s office, filed about two weeks ahead.
- Block party permit: submitted to the Mayor’s office at City Hall; the city asks for two weeks to process. See City of Florissant permits.
- Special use permit: questions go to Florissant Public Works.
- City parks: pavilions are reserved by Florissant residents, and outside vendor requests need written approval from the Parks Director. Read the pavilion reservation rules.
- HOA rules: some subdivisions limit how long a unit may be visible from the street. Check covenants before a long remodel.
What about St. Louis County, the City of St. Louis and state roads?
Unincorporated St. Louis County roads need a county right-of-way or special-use permit for anything placed in the road. The City of St. Louis requires a blocking right-of-way permit for street or sidewalk placement and a special event permit 30 days ahead for public events. State routes like Lindbergh need MoDOT approval.
- St. Louis County permits for work on county roads
- City of St. Louis Streets Department permits
- City of St. Louis special event permit
- MoDOT right-of-way permits
Rules change, so call the office before your date. We do not pull permits for you, but we will place the unit exactly where the permit allows.
Where is the best spot to place a porta potty?
The best spot is flat, firm ground within about 15 feet of where the truck can stop, at least 10 feet from windows and doors, 20 feet from food, and out of low areas that collect rain. Face the door away from guests or the street. Keep the path clear of cars, wires and low branches.
- Gate width: a standard unit needs 48 inches; a wheelchair-accessible unit needs about 66 inches.
- Ground: driveway, patio, gravel or dry, level lawn. No steep slopes.
- Access for service: on jobsites the service truck returns every week, so keep the route open.
- Wind: open fields need a flat spot away from the edge; we can stake units on request.
- Mark it: chalk, a cone or a photo by text. The driver calls about 30 minutes ahead.

Can the porta potty go on the street in front of my house?
Street placement needs city approval in Florissant and most St. Louis County cities. Keep the unit on your driveway to skip the permit.
Can the driver move it if I change my mind on arrival?
The driver can adjust placement on delivery day if the new spot is level and reachable. Moving a used unit later is a separate service call.
Is there a charge if the driver cannot place the unit?
If the spot is blocked or unreachable and no alternative works, a trip charge can apply. Text a photo of the spot ahead of time to avoid it.
The address does not show on Google Maps. What now?
