Gaithersburg Block Party Checklist: Permit and Porta Potties
A block party in the City of Gaithersburg needs a city permit, a site plan and a restroom plan. This checklist covers all three in the order you need them.

The City of Gaithersburg block party permit applies to gatherings under 200 people on a local residential street without a bus route, closed to the public and ending before 9 pm. The fee is $50 when filed 4 or more weeks ahead and $75 when filed later. The city takes no applications 2 weeks or less before the party.

How many porta potties for a block party?
A block party of 100 people for up to 4 hours needs 2 standard porta potties. A 6-hour party for 150 people needs 5. If beer or wine is served, add 1 for every 3 units. Add a hand wash station when food is served.
| Party | Units | Add |
|---|---|---|

| 100 people, 4 hours | 2 | 1 hand wash |
| 150 people, 6 hours | 5 | 2 hand wash |
| 190 people, 6 hours with beer | 8 | 2 hand wash, 1 ADA unit |
