Seattle Backyard Beehive Ordinance: 4 Hives, Flyway Fence & State Registration

Seattle has one of the most detailed and well-written urban beekeeping ordinances in the country. Up to 4 hives, no permit required from the city, but a state registration requirement and specific flyway fence rules. Here's the complete picture.

Seattle Beekeeping Quick Summary
Maximum hives: 4 · City permit: Not required · State registration: Required (WA Dept of Agriculture) · Setback: 25 ft from property line (or flyway fence option) · Code reference: Seattle Municipal Code § 23.42.052

Seattle Municipal Code § 23.42.052

Seattle's beekeeping provisions are in Title 23 (Land Use Code), Section 23.42.052. The key provisions in plain language:

  • Up to 4 managed honeybee colonies are permitted as an accessory use on any residential lot
  • No city permit is required for up to 4 hives
  • Hives must be set back at least 25 feet from any property line — OR — a flyway barrier must be installed (see below)
  • A water source must be provided on-site to prevent bees from seeking water at neighboring properties
  • Hives must be managed to prevent swarming; beekeepers are encouraged to register with the WA Department of Agriculture for swarm management assistance

The Flyway Fence Option

The flyway fence is Seattle's alternative to the 25-foot setback. If your lot cannot accommodate a 25-foot setback from property lines (common on Seattle's densely packed parcels), you can instead install a solid fence, wall, or dense hedge at least 6 feet tall positioned between the hive entrance and the nearest property line.

The physics: bees flying out of a hive entrance blocked by a 6-foot barrier are forced to ascend to at least 6 feet of altitude before crossing the property line. At that height, they fly over neighbors' heads rather than at face level, dramatically reducing the likelihood of stinging encounters.

Specific flyway fence requirements in Seattle:

  • Minimum 6 feet tall
  • Solid enough to force vertical flight — solid wood fence, masonry, or a dense hedge (not open lattice or chain link)
  • Positioned within 10 feet of the hive entrance, between the entrance and the property line
  • Flyway fence option applies to any property line within 25 feet of the hive — if only one side is within 25 feet, you only need a flyway fence on that side

Washington State Registration Requirement

Washington State requires that all managed honey bee colonies be registered with the Washington State Department of Agriculture (WSDA). This is a state-level requirement that exists independently of Seattle's city code — Seattle doesn't require a city permit, but the state does require registration.

How to register in Washington:

  1. Visit the WSDA's Pesticide Management Division website or call (360) 902-2070
  2. Complete the Honey Bee Registration form
  3. Pay the registration fee (currently free for hobby beekeepers with fewer than 5 colonies)
  4. Registration is annual and renews automatically
  5. A state apiary inspector may visit registered hives annually; this is a benefit, not a threat — inspectors help identify disease and provide free expertise
The Detail Most Guides Miss
Seattle's ordinance requires a water source "within the area occupied by the hive" — not just anywhere on your property. This means a water source accessible to bees within the hive area itself, not just a birdbath in the front yard. A shallow dish with pebbles or corks (so bees can land without drowning), refreshed weekly, satisfies this requirement. Without it, your bees will find water at neighboring properties — and that neighbor interaction is the most common source of bee-related complaints in Seattle.

Seattle's Bee-Friendly Infrastructure

Seattle is notable among major U.S. cities for having a formal swarm management network. The city works with the Puget Sound Beekeepers Association, which maintains a swarm list of registered beekeepers willing to capture swarms that land on public or private property. If your hive swarms onto a neighbor's property, contacting the PSBA swarm line typically resolves the situation within hours at no cost to anyone.

Frequently Asked Questions — Seattle Bees

Yes, using the flyway fence option. A 6-foot solid fence on all sides within 25 feet of your hive entrance satisfies the setback alternative. In practice, most Seattle lots have at least one side with a 6-foot fence already. Position your hive with the entrance facing the fence, and the bees will be directed upward on exit. This is a workable setup even on Seattle's compact 3,000–5,000 square foot lots.
Not legally — one hive is permitted. But experienced beekeepers strongly recommend starting with at least two hives so you can compare colony behavior (one active colony makes it hard to know if you have a problem), and so you have genetic material available if one colony dies. Seattle's 4-hive limit gives you room to grow as your experience increases.
You have potential civil liability for stinging incidents, particularly if you're not in compliance with the ordinance (no flyway fence, bees seeking water at their property, etc.). Homeowner's insurance generally covers bee-related incidents under general liability, but check your specific policy. Compliance with the ordinance and maintaining a calm, well-managed colony are the best protections. Aggressive colony behavior is often a sign of a queen quality issue — re-queening is inexpensive and dramatically reduces stinging tendency.
