Maricopa, AZ Short-Term Rentals: Registration Rules (2026)

Arizona short-term rentals are licensed at the state level rather than through a county registry, and the City of Maricopa has not adopted a dedicated STR registration chapter in its municipal code. To 'register' as a Maricopa host, the owner applies to the Arizona Department of Revenue for a Transaction Privilege Tax (TPT) license and reports rentals under transient-lodging classifications (the state uses business code 025 for transient lodging). The Department of Revenue notes that anyone engaged in transient lodging - rentals of fewer than 30 days - must hold a TPT license. State law A.R.S. 9-500.39 authorizes a city to 'require the owner of a vacation rental or short-term rental to obtain and maintain a local regulatory permit or license' and to condition that license on items such as proof of a TPT license, but only at a fee not exceeding the city's actual cost or $250, whichever is less. The City of Maricopa's Title 5 business-regulation chapters do not include such a short-term-rental registration scheme as of this research, so the practical registration step is the state TPT license. Hosts should confirm whether a city business license under Chapter 5.05 applies to their activity and check with Maricopa Development Services for any newly adopted requirements.
