If you own a short-term rental in Flagstaff, 2026 is the year your compliance file gets thicker. The city adopted updates to Chapter 3-12 (Short-Term Rentals) and Chapter 3-10 (User Fees) that took effect July 1, 2026, and they add insurance, guest screening, and fire safety obligations on top of the license you already carry (City of Flagstaff, Short-Term Rental Ordinance Updates).
The stakes are simple. Flagstaff can fine you $500, then $1,000, then $3,500 for verified violations at the same property inside a 12-month window, and it can suspend your license for up to a year (Flagstaff City Code Ch. 3-12). A suspended license in a market that books out for summer, Homecoming, and ski weekends is a revenue problem, not a paperwork problem.
Everything below was verified against City of Flagstaff and State of Arizona sources on August 25, 2026. This is general information, not legal or tax advice. Confirm your specifics with the City of Flagstaff and a licensed attorney or CPA before you act.
Who this applies to
Flagstaff requires a license for each STR, and it is unlawful to rent or even offer to rent without one. An online listing advertising a Flagstaff address for transient lodging is prima facie evidence that you are operating an STR in the city, and if you are unlicensed the code requires you to stop until you have the license (Flagstaff City Code Ch. 3-12).
One structural rule: if your property contains an accessory dwelling unit with a Certificate of Occupancy issued on or after September 14, 2024, you must live on the property as your primary residence to license the STR (City of Flagstaff). That mirrors state law, which allows the owner-occupancy condition for ADUs built on or after that date (A.R.S. § 9-500.39).
What changed effective July 1, 2026
| Requirement | 2026 status | Can a platform satisfy it? |
|---|---|---|

Timing matters: most requirements attach at your next renewal, but the city states that insurance, safety equipment, the posted notice, and neighbor notification apply prior to any rental (City of Flagstaff). Do not wait for a renewal notice to buy a fire extinguisher.
The fee
The annual license fee is now $250, which the city describes as the state maximum (City of Flagstaff). State law caps a local STR license fee at the actual cost of issuance or $250, whichever is less (A.R.S. § 9-500.39). The fee is nonrefundable and not prorated — it covers a full year whether or not you rent all year (Flagstaff City Code Ch. 3-12).
Insurance
You must carry at least $500,000 in liability insurance before offering or renting the STR, satisfied if you advertise through a marketplace such as Airbnb or Vrbo that provides equivalent coverage (City of Flagstaff). That tracks the state standard, which allows cities to require $500,000 in aggregate coverage or equal-or-greater marketplace coverage (A.R.S. § 9-500.39). My practical read: if you take any direct bookings, do not lean on platform coverage. Platform protection generally follows platform reservations.
Background checks
No later than 24 hours before each stay, you or your designee must check the booking guest against the National Sex Offender Public Website, satisfied if your marketplace performs the check (City of Flagstaff) — a waiver state law requires (A.R.S. § 9-500.39).
Fire and life safety
Flagstaff's requirements are specific:
- Smoke alarms outside each sleeping area, inside each sleeping room, and on every story including basements, with battery backup, tested regularly.
- Carbon monoxide detectors in STRs with fuel-burning appliances, fuel-burning fireplaces, or an attached garage — outside each sleeping area and within each sleeping unit.
- Fire extinguisher rated at least 2-A:10-B:C, mounted visibly or clearly marked, serviced and tagged at least annually or after each use.
- Egress: at least two distinct and unobstructed exit paths, kept clear of furniture, storage, debris, snow, and ice at all times.
All four are city requirements with no marketplace substitute (City of Flagstaff).
During Stage 2 or higher fire restrictions, you must remove, disable, or securely lock any fire pit, open-flame barbecue, or grill. Gas and pellet appliances with a functional on/off switch are exempt, and devices may be restored at Stage 1 or Stage 0 (City of Flagstaff). If your listing photos feature a fire pit, plan for a summer where that amenity is locked and your messaging says so before arrival.
The posted notice
Chapter 3-12 requires a notice displayed inside the STR within ten feet of the primary entrance, covering prohibited uses, the emergency contact, and the city STR license number (Flagstaff City Code Ch. 3-12). As of July 1, 2026, it also includes winter parking restrictions, fire restriction information with a link to current restrictions, waste and recycling collection information, and the human trafficking hotline; the complaint hotline came off because complaints are now filed online. Updated posting language is included automatically on licenses issued on or after July 1, 2026, and owners can print the new notice early (City of Flagstaff).
Neighbor notification
Before the first rental, you must notify neighboring properties in writing, and again when emergency contact information changes. The city describes the scope as adjacent, across, and diagonally adjacent properties, updated to align with state law, and notes that the city's public STR map provides ongoing notification (City of Flagstaff).
Chapter 3-12 spells out the mechanics. The notification must include the city-issued STR license number, the physical address, and the emergency point of contact's name, physical address, email, and 24-hour phone number. In a multifamily building, notice goes to residents on the same floor plus the units directly above and below. You then submit an attestation of compliance listing each address notified, how you notified them, and who is attesting. Additional notification is required within 10 days of any change in the emergency point of contact, and again at renewal (Flagstaff City Code Ch. 3-12).
Taxes you owe on a Flagstaff STR
A state transaction privilege tax (TPT) license from the Arizona Department of Revenue is required for every property used as a short-term rental, whether or not you use a property manager or a listing platform, and the TPT number goes on your city STR application (City of Flagstaff, STR Property Owners).
On ADOR's rate table effective August 1, 2026, the Coconino County transient lodging rate under business code 025 (which includes the state portion) is 6.90%, and the City of Flagstaff hotels rate under business code 044 is 4.486% (ADOR Transaction Privilege and Other Tax Rate Tables, 8/1/2026). Added together that is roughly 11.386% on a Flagstaff nightly stay — my arithmetic from those two published figures, so confirm your own combined rate using ADOR's rate look-up tool.
How to comply, step by step
- Get your Arizona TPT license at AZTaxes.gov. The state TPT license fee is $12 per location (ADOR).
- Line up your emergency point of contact. This person must be on the premises or reachable by phone or text within 60 minutes of a police request concerning an emergency (Flagstaff City Code Ch. 3-12).
- Buy the insurance — at least $500,000 in liability coverage, in force before you rent (City of Flagstaff).
- Install and document safety equipment: smoke alarms, CO detectors where applicable, a tagged 2-A:10-B:C extinguisher, two clear exits.
- Apply for the STR license on the city's application, including the property address, owner and designee contact details, the TPT license number and location code, your acknowledgment of applicable laws, the sex offender and felony attestation, and the $250 fee (Flagstaff City Code Ch. 3-12).
- Notify neighbors in writing once you have the license number, then file the attestation with the city.
- Post the notice within ten feet of the primary entrance, using the current required language.
- Put your city STR license number in every advertisement — that is a code requirement, not a courtesy (Flagstaff City Code Ch. 3-12).
- Build the pre-stay routine: NSOPW check within 24 hours of each stay if your platform does not do it, plus a fire restriction check before every arrival.
- Calendar your renewal. The license runs one year from issuance, and renewal requires the fee plus a fresh neighbor notification (Flagstaff City Code Ch. 3-12). Questions go to ShortTermRental@flagstaffaz.gov (City of Flagstaff).
Not sure you're compliant
Compliance is table stakes. Getting booked is the harder problem, and it is the one I actually solve. Bring me your listing URL and I'll spend 15 minutes telling you the top three things limiting its visibility. Free, and there's no pitch at the end.
Penalties for non-compliance
- Verified violations at the same property within 12 months: $500 first, $1,000 second, $3,500 third and each subsequent violation (Flagstaff City Code Ch. 3-12).
- Failure to apply for a license within 30 days after written notice: up to $1,000 per month (Flagstaff City Code Ch. 3-12).
- Failure to provide or maintain emergency contact information: $1,000 for every 30 days, after at least 30 days' written notice (Flagstaff City Code Ch. 3-12).
- Suspension: up to 12 months for three verified violations in 12 months, or for a single serious violation such as a felony committed at the property by the owner or designee, or knowingly allowing the STR to be used as an event venue, retail space, restaurant, or banquet space. You may appeal to the City Manager within 10 calendar days, but an appeal does not stay the suspension (Flagstaff City Code Ch. 3-12).
Ordinance No. 2026-11, which adopted the 2026 code updates, confirms the $500 / $1,000 / $3,500 civil infraction structure and an effective date of July 1, 2026 (City of Flagstaff, Ordinance 2026-11).
Common mistakes I see
- Assuming the platform covers everything. Platforms can satisfy the insurance and background check requirements. They cannot satisfy the license, the posted notice, neighbor notification, or your fire equipment (City of Flagstaff).
- Letting the emergency contact go stale. A phone number tied to a former co-host is a $1,000-per-30-days exposure, and it triggers a new neighbor notification within 10 days when it changes.
- Ignoring fire restriction stages. Guests will use the fire pit if it is usable. During Stage 2 or higher, it must be removed, disabled, or locked.
- Skipping renewal-time neighbor notification. Renewal is not just a payment; the code requires notification again at renewal.
- Leaving the license number off one listing. Code requires the number on each advertisement, and multiple advertising violations only merge into one verified violation if you actually come into compliance within 30 days.
- Treating snow as an exception. Egress paths must stay clear of snow and ice. In Flagstaff, that is an operational commitment, not a checkbox.
Compliance is the floor, not the strategy. Once your Flagstaff license, insurance, and safety file are clean, the next question is whether your listing is actually being seen by the guests who book Flagstaff — and in a market this seasonal, visibility gaps show up as empty shoulder-season weeks rather than obvious problems. I spent years on the other side of the platform as an Airbnb Market Manager, and I offer a free 15-minute listing visibility diagnostic: a straight read on how your listing is performing in search and what is holding it back. If that would be useful after the paperwork, reach out.
