Are there regulations on the maximum permissible number or types of pets?
Yes. Limits on the types and number of pets are contained in the Hillsborough Municipal Code. HMC 6.16.030, which limits residents to 5 dogs. A horse may be kept if the resident has a minimum 2 acre lot. Chickens and other fowl are allowed by permit only (issued by the City Manager’s Office), with several restictions on the location of cages and noise.
