Frequently Asked Questions

Does the Mat-Su Borough require a permit for an outdoor festival?
Yes, if the event is expected to draw more than 500 people and is not run by a government agency, held entirely inside an enclosed building, or already covered by a Title 17 conditional use permit. MSB § 8.55.030 makes it unlawful to operate, sponsor or promote such a gathering without first obtaining a special events permit from the Planning and Land Use director.
Does this permit requirement apply inside Wasilla or Palmer?
No. MSB § 8.55.020 limits Chapter 8.55 to areas of the borough outside the incorporated cities. An event inside Wasilla, Palmer or Houston is regulated under that city's own code, not the borough's mass gathering rules.
How far in advance must an organizer apply?
MSB § 8.55.050 requires the application, on forms from the director and accompanied by the assembly's fee, at least 90 days before the first day of advertising for the event, giving the borough time to review the security, medical, sanitation and traffic plans before promotion begins.
What happens if someone holds the gathering without a permit?
MSB § 8.55.100(B) makes failure to obtain the required permit a minor infraction, and the borough's remedies under the chapter are cumulative of any other remedy available at law, so officials can also act to stop an unpermitted gathering already underway.
