Portland Title 13 caps the number of dogs and cats per household before a kennel or multiple-animal permit is required, with enforcement handled by Multnomah County Animal Services.
Under Portland City Code Title 13 and Multnomah County Code, residences may keep up to four dogs or cats over four months of age without a special permit. Households exceeding that count must apply for a multiple-animal permit through MCAS, which reviews property size, neighbor notice, and sanitation. Commercial kennels and rescues require additional zoning approval under Title 33. Foster homes registered with licensed shelters are generally exempt from the cap during active fostering. Permits may be denied or revoked for nuisance complaints or sanitation violations.
Exceeding the limit without a permit can trigger MCAS warnings, citations, and a requirement to rehome animals. Repeat violations may result in escalating fines and inspection requirements.
