Who Handles Local Rules
For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, the government to ask depends on where the site is. Of the 28 listed New Hampshire places, 13 are incorporated, 10 are unincorporated Census-designated places and 5 are towns or townships with their own government. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the town or township, or the county. We don't say whether a permit is needed; each city page names who to ask.
What to Ask For
- Expected attendance, including staff, vendors and volunteers
- Event hours and whether it runs over several days
- Whether alcohol or food will be served
- ADA units (at least 5% of each cluster) and hand-wash stations
- Delivery and pickup windows the venue allows
