What kinds of events do you serve in Frisco?
Dennis Rental Works serves backyard birthday parties, family reunions, church picnics, school fundraisers, customer-appreciation days, sports tournaments, block parties and graduation parties. Most event callers need 1–4 units. Larger festivals and runs get a planned layout with accessible units and handwash stations.
Do I need a city permit for my Frisco event?
Restrooms alone do not need a permit in Frisco. The whole event needs a Frisco special event permit when it has 100 or more attendees, food vendors, street closures, tents over 400 square feet or a city park location. Frisco says applications filed less than 30 days ahead may be denied, and the permit fee is $150.
Apply through the City of Frisco Special Event Permitting page, or call 972-292-6651. Confirm restroom expectations with the committee or your venue.

Questions renters ask us
How many porta potties do I need for 100 people?
For 100 guests at a 4-hour event, plan 2 standard porta potties. Add 1 unit if alcohol is served, for 3 total. For a 6-hour event, plan 3 units, or 4 with alcohol. Include 1 wheelchair-accessible unit when guests may need one.
Can I rent just one porta potty for a birthday party at my house?
Yes. One standard porta potty covers about 50 guests for a 4-hour backyard party. Dennis Rental Works delivers the day before and picks up the next business day. Many Frisco families choose a deluxe flushing unit with a sink for parties, because guests do not see the tank.
Do I need a handicap porta potty at my event?
Where accessible restrooms are required, the 2010 ADA Standards section 213.2 calls for at least 5% of portable units in each cluster, and no fewer than one, to be accessible. Dennis Rental Works recommends at least 1 accessible unit for any event of 100 or more guests.
Can you drop it off the day before my event?
Yes. Day-before delivery is our standard for events, at no extra cost. Your restroom is set, clean and stocked before guests arrive, and you are not depending on a same-day delivery window. Pickup is usually the next business day after the event.
Do I need a permit for a porta potty at my Frisco event?
Restrooms alone do not need a city permit. A Frisco special event permit is needed for events with 100 or more attendees, street closures, food vendors, large tents or park locations. Frisco says applications filed less than 30 days ahead may be denied. Call the Special Events Permitting Committee at 972-292-6651.

Dennis Rental Works delivers on Saturdays. The office and trucks are closed on Sundays. For a Saturday or Sunday event, we drop the unit Friday (or Saturday morning) and pick it up Monday. The extra days do not cost more.
How much is a porta potty for one day or a weekend party?
One standard porta potty for a one-day or weekend event usually totals about $225–$375 with delivery and pickup included. The unit arrives clean and stocked. A deluxe flushing unit with a sink runs about $350–$500 for the same event. Quotes are itemized before you pay.
