Summary

Washington County requires a permit for any 'outdoor mass gathering', an assembly of more than 3,000 people lasting 24 to 120 hours in open space, under WCC § 8.52.020(A). The Department of Health and Human Services reviews applications filed at least 140 days ahead, in unincorporated Washington County.

City-specific rules exist: Beaverton, and Hillsboro have their own parade permits rules that differ from Washington County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Violations & Fines

Holding, promoting or allowing an outdoor mass gathering of more than 3,000 people for 24-120 hours without a county permit violates § 8.52.020(A), punishable under § 8.52.220(A) by a fine of up to $10,000 as provided in ORS 433.990.

Frequently Asked Questions

Does a small neighborhood parade need a Washington County permit?

Chapter 8.52 only covers 'outdoor mass gatherings': assemblies of more than 3,000 people expected to last between 24 and 120 hours, held in open space rather than a stadium or arena. A small parade or block party well under that size and duration falls outside this specific permit chapter.

How far ahead must an organizer apply for an outdoor mass gathering permit?

Section 8.52.040(A) requires the application at least 140 days before the anticipated event date; applications filed later 'shall not be processed.' The application must include a site map, attendance estimate, security plan, fire-protection sign-off and sanitation details, and go to the county's Department of Health and Human Services.

What's the penalty for holding an unpermitted outdoor mass gathering in the county?

Section 8.52.220(A) makes an unpermitted gathering under § 8.52.020(A) punishable by a fine of up to $10,000, tied to ORS 433.990. Separately, violating permit conditions found in §§ 8.52.210 through 8.52.220(B) is an infraction carrying a civil penalty of up to $2,500 per violation, with each day of noncompliance a distinct violation.
