Unincorporated Maricopa County imposes no cap on the number of nights a short-term or vacation rental may operate. Arizona Revised Statutes Section 11-269.17 preempts counties from restricting STRs based on classification, use, or occupancy. Counties may regulate fire, building, health, sanitation, noise, and nuisance issues but cannot ban or limit nights.
Arizona Revised Statutes Section 11-269.17, originally enacted as SB 1350 (2016) and updated by SB 1168 (2022), preempts a county from restricting the use of, or regulating, vacation or short-term rentals based on their classification, use, or occupancy. Counties retain authority to enforce fire and building codes, health and sanitation, transportation and traffic control, hazardous-waste rules, and zoning ordinances of general application addressing noise, property maintenance, and nuisance. A county may require a permit, charge a fee not to exceed the actual cost of issuing it or $250 (whichever is less), require $500,000 liability coverage (or use of an online marketplace providing equivalent coverage), require an emergency contact, and require notice to adjacent owners before the first rental. Maricopa County does not issue a separate STR license for unincorporated areas; the Arizona Department of Revenue requires a TPT license for transient lodging. Confirm with Maricopa County Planning & Development at (602) 506-3301.
There is no nightly cap to violate. Operating without an Arizona TPT transient-lodging license, or violating county noise (Ordinance P-23), property maintenance, or building/fire code rules, is enforceable through the responsible county department.
