Seattle's domestic fowl allowance covers ducks and chickens under the same 8-bird limit — no permit, 10-foot setback. But ducks have water management requirements chickens don't. Here's what Seattle keepers actually need to know.
Quick Summary
Limit: 8 domestic fowl total (ducks + chickens combined) · Drakes: Prohibited (noise) · Permit: Not required · Setback: 10 ft from property line · Code: Seattle Municipal Code § 23.42.052
Seattle's Domestic Fowl Allowance Covers Ducks
Seattle Municipal Code § 23.42.052 permits up to 8 domestic fowl per residential lot — and ducks count within the same limit as chickens. The combined total of ducks and chickens (and any other domestic fowl) cannot exceed 8. If you keep 5 chickens and 3 ducks, that's your 8. No city permit is required for any combination up to 8 birds.
Drakes (male ducks) are prohibited in residential zones under Seattle's animal noise ordinance — the same provision that bans roosters. Female ducks produce the characteristic quack; drakes produce a quieter raspy whisper, but the ordinance bans males regardless as a categorical rule.
Water Management — Seattle's Practical Reality
Ducks need head-submersion water daily for eye and nostril cleaning. A 5-gallon rubber livestock tub works well. The challenge in Seattle: the city's abundant rainfall means duck-water splash combines with rain to create significant mud. Hardware cloth under the run area, changed straw regularly, and a rain-sheltered water area prevent the sanitation complaints that lead to code enforcement in duck setups.

Frequently Asked Questions
Yes — Seattle's ordinance makes no distinction about housing. Mixed flocks work practically in Seattle, though ducks and chickens have different water and bedding needs. Ducks will foul chicken waterers with mud and debris. Separate water stations — one dry chicken-style waterer, one duck tub — work well in mixed setups. Total birds still cannot exceed 8 combined.
Seattle's code uses 'domestic fowl' without breed distinctions — all domestic duck breeds count the same under the 8-bird limit. Domestic Muscovies (raised in captivity) are not subject to federal Migratory Bird Treaty Act restrictions that apply to wild Muscovies. However, Muscovies are notably quiet (they hiss rather than quack), which makes them neighbor-friendly — but the drake ban still applies regardless.
No state registration is required for small-scale domestic duck keeping in Washington. Unlike beekeeping (which requires WA Department of Agriculture registration) or commercial poultry operations (which require WSDA licensing above certain flock thresholds), backyard ducks for personal use have no state registration requirement in Washington.
Seattle's mild maritime winters (rarely below 28°F) are excellent for ducks. Unlike chickens, ducks are cold-hardy and continue foraging and laying through Seattle's wet, mild winters. The main winter management issue is mud — ducks in saturated soil create deep mud quickly. Elevated duck houses with hardware cloth floors let droppings fall through, reducing mud buildup dramatically.
