STR Regulations in Gilbert and Mesa: What Investors Need to Confirm Before Buying a Rental

by Dana Massey

You found the numbers first. The comps, the nightly rate, the cap rate that finally pencils. Then you find out the city might not let you operate it the way your spreadsheet assumes.

TL;DR: Arizona state law (A.R.S. § 9-500.39) stops Gilbert and Mesa from banning short-term rentals outright, but it lets both require a local license, proof of liability insurance, emergency contact information, and neighbor notification. Mesa has required a city license since February 1, 2023. Gilbert's Town Council approved its short-term rental ordinance in June 2023 and runs licensing through an online portal. Every STR owner in Arizona also needs a state TPT license from the Department of Revenue. The main 2026 bill that would have given cities more authority stalled in the Senate, and the rules can still change, so confirm current requirements with each city before you write an offer. This is general information, not legal or tax advice. For the wider East Valley rental and growth picture, see my East Valley market data guide.

Arizona's State Law Sets the Floor

Cities and towns can't prohibit short-term rentals, per A.R.S. § 9-500.39. Under that statute a city can require a local permit or license, emergency contact information, neighbor notification, the permit number on every ad, and liability insurance of at least $500,000 in the aggregate, or booking through an online lodging marketplace that provides equal or greater coverage. The permit fee is capped at the actual cost of issuing it or $250, whichever is less. Civil penalties for verified violations at the same property within 12 months run up to $500 or one night's rent, whichever is greater, for the first, up to $1,000 or two nights' rent for the second, and up to $3,500 or three nights' rent for the third and any after that. Three verified violations in 12 months can also put the license up for suspension for as long as 12 months. That's my plain-language read of the statute as of October 2026. Read the text yourself, and confirm how it applies to a specific property with a real estate attorney.

What Gilbert Requires Right Now

Gilbert's Town Council approved a short-term rental ordinance in June 2023, and owners have to get and keep a Town of Gilbert Short-Term Rental License. Licensing runs through an online portal from Neumo, formerly GovOS. Per the Town's short-term rentals page in October 2026, the license and the annual renewal are $250 per property effective October 1, 2026. Before you apply, the Town asks for a state TPT license with the property address on it, registration with the Maricopa County Assessor, and neighbor notification. Gilbert short-term rentals also pay the Town's transaction privilege tax and a transient (bed) tax. Confirm the current fee and renewal cycle directly with the Town.

What Mesa Requires Right Now

Mesa's short-term rental license has been required since February 1, 2023. Per the City of Mesa's license page in October 2026, the license goes only to the deeded owner, costs $250, lasts one year, and has to be renewed at least 45 days before it expires. Mesa asks for proof of a state TPT license, a designated emergency contact, neighbor notification, and at renewal proof of at least $500,000 in liability insurance. The city counts any stay of 29 days or less as short-term. Don't assume a rental you're buying is licensed. Four months after the rule took effect, fewer than a quarter of Mesa's roughly 1,700 short-term rentals had a license, per an Arizona Republic report summarized by Scottsdale REALTORS in July 2023.

The Tax Layer Nobody Budgets For

Every Arizona STR owner needs a Transaction Privilege Tax (TPT) license from the Arizona Department of Revenue, and the Department says you still file a $0 return for any period you didn't rent the property (ADOR, short-term lodging). Gilbert's page says owners who book only through a platform like Airbnb or Vrbo still keep their own license and file. Both Gilbert and Mesa sit in Maricopa County, and rental properties there are registered with the Maricopa County Assessor. Have a CPA who works with short-term rentals set up the filings.

What Happened in the 2026 Legislative Session

The main bill didn't make it. House Bill 2429 would have let cities limit occupancy in sleeping areas, suspend a license over a serious building code violation, and count three nuisance violations over 24 months instead of 12. It passed the House 37 to 14 in March and never got a Senate committee hearing, per the Arizona Capitol Times in May 2026. Earlier versions that would have let cities cap the number of short-term rental licenses and set minimum distances between them weren't part of this year's bill, and the sponsor told the paper she's already thinking about next year.

Due Diligence Checklist

Confirm current license status directly with Gilbert or Mesa's licensing office
Verify HOA rules separately. CC&Rs can restrict or block STRs, and state law doesn't stop an HOA from doing that
Pull the property's current TPT license status if it's an existing rental
Model cap rate with licensing fees, lodging taxes and compliance costs built in
Have a real estate attorney and a CPA review the plan before you close
