Are Roof Rats Legal in Phoenix? Keeping, Breeding & Selling

Roof Rat LawsArizona › Phoenix

Summary. Good news if you live in Phoenix, with one wrinkle worth understanding. Arizona does not restrict keeping a pet rat, and Phoenix treats a rat kept as a pet as an ordinary ‘animal,’ not a regulated ‘rodent,’ so a domesticated pet roof rat is allowed, the same as Arizona. The wrinkle: Phoenix City Code 8-7 does declare it a nuisance to ‘keep rodents’ within the city, with a 20-foot setback from neighbors and limits like ’25 head of rodents per half-acre.’ Read in context, that rule targets outdoor rodent husbandry (it counts ‘head’ of rodents by the half-acre and requires enclosures to keep them off neighbors’ land), not a pet rat in a cage indoors. Phoenix’s animal code (8-1) makes this clear: a rodent ‘known to be kept as a pet,’ or ‘clearly marked and denominated as being a pet, such as rodents wearing collars or harnesses,’ is treated as an ‘Animal’ (a normal pet), not as a controlled ‘rodent.’ So a pet roof rat is allowed in Phoenix. If you want certainty in writing, you can ask Phoenix directly, and we can help.

Arizona does not restrict keeping a pet rat. Phoenix City Code 8-7 (‘Poultry and rodents’) declares it a nuisance to keep ‘rodents’ within the city with a 20-foot property-line setback and head-count limits (no more than 25 head of rodents per half-acre), but the provision is structured for outdoor rodent husbandry, not an indoor caged pet. Phoenix City Code 8-1 expressly carves pets out of the ‘rodent’ category: the code’s exclusion of rodents ‘does not apply to … any rodent known … to be kept as a pet or any rodent clearly marked and denominated as being a pet, such as rodents wearing collars or harnesses,’ so a pet rodent is an ‘Animal’ (an ordinary pet), not a regulated ‘rodent.’ On that reading a pet roof rat is allowed, the same as Arizona. Confidence is medium only because the keeping nuisance clause is worded broadly; written confirmation from the City would remove all doubt.

Phoenix has no pet-rodent breeding restriction; the only rodent-specific rule (8-7) is an outdoor-husbandry nuisance provision with head-count and setback limits, not a ban on keeping or raising pet rats indoors. Arizona’s permissive state rule applies.
