Portland's domestic fowl allowance covers ducks within the same restrictive 3-bird, annual-permit model as chickens. Here's how Portland's rules apply specifically to duck-keeping.
Quick Summary
Limit: 3 domestic fowl total (ducks + chickens combined) · Drakes: Prohibited · Permit: Annual permit ($31/year) · Location: Rear yard only · Code: Portland City Code § 13.05.015
Portland's 3-Bird Limit Applied to Ducks
Portland City Code § 13.05.015 permits up to 3 domestic fowl — any combination of ducks and chickens — with an annual $31 permit from Portland Bureau of Development Services. Portland's 3-bird limit is among the most restrictive of any major West Coast city, and it applies to ducks and chickens combined.
If you want both species, your maximum is 3 total: perhaps 2 ducks and 1 hen, or 1 duck and 2 hens. Drakes and roosters are both prohibited under Portland's noise provisions.
Portland's Rain and Duck Water Management
Portland's heavy rainfall (50+ inches/year) is actually an asset for duck-keeping — ducks in Portland have natural puddles and moisture to forage in. The challenge is overflow management from duck water containers combining with rain. Use a gravel or compacted bark chip base under the duck area to prevent the standing-water complaints that can trigger nuisance enforcement.
Why Ducks Work Well Within Portland's 3-Bird Limit
Three female ducks are a productive and manageable small flock. Khaki Campbell ducks, for example, produce 250–340 eggs per year each — potentially more than 3 chickens from the same space. Ducks are also quieter than hens (female ducks quack, but less persistently than chickens), which matters in Portland's dense neighborhoods where the annual permit renewal depends on no neighbor complaints on record.

Frequently Asked Questions
For egg production, possibly yes. Khaki Campbell ducks produce more eggs annually than most chicken breeds and continue laying through Portland's short winter days without supplemental lighting. Ducks are also more disease-resistant and cold-hardy than chickens. The trade-off: duck eggs are larger and richer (some people prefer them), but the market for duck eggs at farmers markets is smaller. For backyard production under a 3-bird limit, 3 Khaki Campbells are a strong choice.
Yes — one annual permit covers your entire domestic fowl allowance of up to 3 birds, any combination of ducks and chickens. You don't need separate permits for each species. The renewal process is the same: confirm your bird count, confirm no roosters or drakes, pay the $31 fee annually at Portland Bureau of Development Services.
Khaki Campbell (top layer, 300+ eggs/year, adaptable to wet conditions), Welsh Harlequin (excellent layer, calm temperament, beautiful plumage), and Buff (friendly, moderate layer, handles Portland's wet winters well). Avoid Muscovies if you want reliable egg production — they're broody and less consistent layers. All handle the rain excellently.
