Pasco, WA Animal Ordinances: Pet Limits (2026)

030(6), in the R-15 Low Density Residential District, permits "the keeping of dogs and cats, provided such number of animals does not exceed three dogs and three cats" as an accessory use to a single-family home; the identical three-and-three limit repeats verbatim across Pasco's other residential zoning chapters, including R-T, R-S-12, R-1, R-2, R-3, and R-4. 030(10) layers on a lot-size exception: on a lot of at least 5,000 but less than 22,000 square feet with only one single-family dwelling, a household may also keep rabbits and chicken hens, up to three of each, but the combined total of dogs, cats, rabbits, and chickens cannot exceed six animals.

That subsection bars any of those animals from roaming or flying onto neighboring properties and prohibits roosters outright. " A separate, larger keeping-of-animals allowance exists for parcels with at least 10,000 square feet of land beyond a 12,000-square-foot house lot, but that provision governs livestock and larger animal units, not household dogs and cats.
