Pima County, Arizona Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a place in Pima County, Arizona and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that you're allowed to, and it isn't Pima County that gets to decide. Arizona stripped that power from counties and towns with a 2016 law that took effect the following year, so the county can't prohibit short-term rentals out in the unincorporated desert around Tucson, and Tucson, Oro Valley, Marana, Sahuarita and South Tucson can't prohibit them inside their own limits either.

Not being able to ban something isn't the same as having nothing to say about it, though, and this county in particular splits hard along its town boundaries. An unincorporated parcel in Vail or the Catalina Foothills carries a 6% county bed tax that a house three miles inside Tucson never pays, while that Tucson house pays a 10% city rate that only arrived in March 2026. Meanwhile the Board of Supervisors spent late 2025 writing to the Governor asking for the authority back, so the settled part of this is settled for now rather than forever.

So let's walk through what it actually takes to do this properly: which licenses exist and which ones don't, what the county assessor needs from you before a guest ever turns a key, the layers of tax stacked on a single night's rent, how enforcement really works when a neighbor complains, and who to call when you get stuck. Every figure below comes from Pima County's, Arizona's or the Arizona Department of Revenue's own pages, checked in July 2026, and where something is still moving I've said so. Before you commit to a purchase here, run the property through BNBCalc first.

Starting a Short-Term Rental Business in Pima County

Before any of those numbers mean much, you need to work out which government is actually yours, because "Pima County" on a mailing address and "Pima County" as a regulator are two different things. County government writes the rules only for unincorporated land, which is most of the map but not most of the housing. Five incorporated municipalities sit inside the county boundary, and each one runs its own show: Tucson, South Tucson, Oro Valley, Marana and Sahuarita. Look your parcel up first, since half of what follows applies to you and half of it doesn't.

For the unincorporated half, the ceiling on what the county may do is A.R.S. § 11-269.17, the county twin of the 2016 preemption law. A county "may not prohibit vacation rentals or short-term rentals," and it may not restrict or regulate them based on their classification, use or occupancy except through the short list the statute spells out. It can act on genuine health and safety grounds, it can enforce noise and nuisance rules the same way it enforces them against any other house, and it can require a local permit. That permit power is the one worth dwelling on, because Pima County has never taken it up.

I went looking for a county short-term rental ordinance and there isn't one, and I checked properly before saying that. The Pima County Zoning Code runs to 63 chapters covering everything from heliports to native plant preservation, yet not one of them addresses rentals, vacation rentals or short-term rentals. Title 5, the county's business taxes and licenses title, contains exactly three chapters, and they're cable communications, pawnbrokers and scrap metal dealers, so there's no general county business license at all, let alone a rental one.

Even the most recent amendment to the zoning code, Ordinance 2026-7 adopted on 26 May 2026, turns out to be about pavement preservation fees for subdividers. So in unincorporated Pima County you file no application with the county, pay no fee, book no inspection and notify no neighbors, because the county chose not to build any of that.

The county would rather things were otherwise, mind you, and it has put that in writing. On 4 November 2025 the Board of Supervisors voted 3-1 to direct the County Administrator to write to state leadership about short-term rentals. That letter went out on 29 October 2025 over County Administrator Jan Lesher's signature, and it's blunt about what the county wants. It cites Airbnb and Vrbo data showing "at least 6000 properties in Tucson are STRs with 90% being single family homes," and it argues the whole question should go back "to local control and local zoning" where county and town leaders can act on it. The fix it proposes is a cap on short-term rentals where they stand, then shrinking the pool "through attrition and change of use."

Nothing in that letter is law, though, and writing to the legislature changes nothing about what you can do tomorrow. Keep it in mind anyway if you're underwriting a ten-year hold, because the county has now named the policy it would adopt the moment the state lets it.

One more constraint sits entirely outside all of this. State preemption binds governments, not neighbors, so a homeowners association can still forbid short-term rentals in its own subdivision through the recorded covenants, and plenty of Green Valley and Oro Valley communities do. The county won't enforce those covenants and can't advise you on them. Read the ones attached to your parcel before you assume state law has your back, since it doesn't reach that far. For the wider state picture, our Arizona short-term rental guide covers the preemption statutes in full.

Short-Term Rental Licensing Requirements in Pima County

Since the county itself asks nothing of you, the licensing you do owe comes from two directions instead: the state above it, and the town beneath it if your address happens to sit in one.

Start with the state, because it applies to every host in the county without exception. Every operator needs a transaction privilege tax license from the Arizona Department of Revenue, applied for through AZTaxes.gov, and it costs $12 per business location. It renews annually, running from 1 January to 31 December, due on 1 January and delinquent after the last business day of that month, with no state renewal fee. Make sure you get this one first, because everything else, including two of the three town licenses, asks you to produce the number.

Next comes the county assessor, and this is the step people skip. A.R.S. § 33-1902 requires the owner of any residential rental property in Arizona, whether it's a twelve-month lease or a two-night booking, to keep the owner's name, address and telephone number on file with the county assessor along with the street address, parcel number and year of construction. The assessor may charge up to $10 for the initial registration and for each change, and you have ten days to update the file after anything changes.

Still, the teeth are worth reading twice, because the statute says outright that residential rental property "shall not be occupied" if the required information isn't on file. The penalty runs to $1,000 plus $100 a month on a newly acquired property that never registers, or $150 per day on one that falls out of compliance, and a tenant can end the tenancy and recover prepaid rent if you don't fix it within ten days of written notice. Both penalties get dismissed if you cure inside that ten-day window, so the cost of a mistake here is really about how fast you respond.

Then there's advertising, which is easy to get wrong on a listing you've already written. Under A.R.S. § 42-5042 your transaction privilege tax license number has to appear in every advertisement of the property, and where a town issues its own short-term rental license, that number goes in instead. The Airbnb and Vrbo listing description is the advertisement.

That leaves the town layer, which is where the county's five municipalities stop resembling each other:

• Oro Valley licenses short-term rentals under Ordinance (O)23-01, adopted 4 January 2023 and effective 3 February 2023, with registration required by 5 May 2023 and enforcement running since 6 May 2023. The town set the fee at $80 a year, matching its ordinary business license, and says openly that the fee can't exceed the cost of providing the service. As of my last check that page was still showing $80, though the most recent version of it I could open dated from August 2025, so do confirm the current figure with the town before you budget it.
• Marana charges a $60 new license fee, of which $40 is refundable if the application is denied, then $40 a year to renew, with a $10 late fee once you're 15 days past expiry. Invoices go out by mail 30 days ahead. The town's short-term rental page also wants any change to the business, owner, location or contact details reported within ten days.
• Tucson has no standalone short-term rental permit ordinance, but it does require its ordinary city business license plus registration for the city's transient rental tax, and its tax treatment of short-term rentals changed in 2026. Our Tucson short-term rental guide works through the city's Chapter 19 mechanics in detail.
• Sahuarita and South Tucson both levy lodging taxes, which are in the table further down. I couldn't confirm from either town's own code whether it runs a separate short-term rental license, since Sahuarita's code has moved to a new publisher and neither site would open for me, so treat that as unchecked rather than as a no and call the town clerk.

Required Documents for Pima County Short-Term Rentals

Knowing which licenses apply is one thing; assembling what each one asks for is where the week actually goes. The unincorporated half of the county needs the least, and the towns ask for progressively more.

• Your transaction privilege tax license number. Every layer wants it: the state to file returns against, the towns as an application prerequisite, and your listings as a matter of statute.
• Proof of registration with the Pima County Assessor under § 33-1902. Oro Valley and Marana both require you to show it. Even where nobody asks, the property legally can't be occupied without it.
• Evidence of liability insurance. Oro Valley wants coverage of at least $500,000 in the aggregate, or evidence that every booking runs through a platform providing equal or greater primary coverage, which is the exact allowance A.R.S. § 11-269.17 and its city twin permit. Marana asks for evidence of liability insurance for every hosting platform you use.
• A 24-hour emergency contact. Oro Valley requires the full name, address and 24-hour telephone number of whoever will answer at 3am, plus contact details for the owner or designee who handles complaints.
• Neighbour notification, and proof you did it. Marana publishes notification templates for single-family and multi-family properties and then wants a signed attestation emailed to [email protected] before your rental start date. Oro Valley requires an attestation of the same thing with the application.
• A background acknowledgment. Oro Valley makes you acknowledge that neither you nor any designee is a registered sex offender, has been convicted of a felony that caused death or serious physical injury, or has a felony deadly-weapon conviction in the past five years.
• Proof of lawful presence if you're applying as an individual in Oro Valley, and the legal name and statutory agent of the entity if you're applying as an LLC.

Assuming you're out of state, one small thing catches owners repeatedly: § 33-1902 lets a non-resident owner designate a statutory agent who lives in Arizona, and the assessor's file has to carry that agent's details. Don't forget to update it if you change agents, because the ten-day clock applies to that change like any other.

Pima County Short-Term Rental Taxes

Once the paperwork is behind you and you're able to take a booking, there's still the tax stack to deal with, and Pima County's is unusual enough that a rate you read on a national blog will almost certainly be wrong for your address.

Two pieces apply everywhere in the county. The state's transient lodging rate is 5.5% under A.R.S. § 42-5010, and Pima County adds a 0.55% transportation excise tax that has applied to every transient lodging business in the county since 1 July 2006. The Arizona Department of Revenue publishes those two together as a single 6.05% figure under business code 025. Everything after that depends on which side of a town line you're on.

The piece that surprises people is the county's own bed tax. Arizona Revised Statutes § 42-6108 lets a county of between 500,000 and 2,500,000 people levy up to 6% on hotel businesses. The statute is explicit that "the tax only applies in unincorporated areas of the county," which is why a house inside Tucson or Marana never pays it. Pima is the only Arizona county in that population band using the power, and it charges the full 6%, effective since 1 January 2006. The Arizona Office of Tourism's own rate sheet states the position plainly: transient lodging in unincorporated Pima County pays a 6% county tax, and that tax "does not apply to transient lodging located within the incorporated cities/towns of Pima Co."

Where the property sits	State plus county	County bed tax	City lodging tax	Total on a nightly stay
Unincorporated Pima County	6.05%	6.00%	none	12.05%
Tucson	6.05%	none	10.00%	16.05%
Oro Valley	6.05%	none	8.50%	14.55%
Marana	6.05%	none	8.50%	14.55%
South Tucson	6.05%	none	5.50%	11.55%
Sahuarita	6.05%	none	4.00%	10.05%

Every rate above is collected by the Arizona Department of Revenue through a single return, so keep in mind that the table is a tax bill rather than a list of offices to visit. The Office of Tourism sheet reproduces four of those six totals independently, which is why I'm comfortable publishing them as sums.

Tucson's row is the one that changed, and it changed a lot. On 16 December 2025 the city passed Ordinance 12215, effective 1 March 2026, creating a "Transient - Non Hotel" tax class at ten percent. That class catches any property not classified as a hotel for property taxation, which in practice means ordinary houses and apartments, while a companion ordinance raised the hotels rate from 6% to 9% and cut the $4 per night bed surtax to zero on the same date. Put the two together and you get an odd result, since a house let by the night in Tucson now pays a higher city rate than the Marriott down the road does. So anything you read describing Tucson at a flat 6% is describing 2025.

Platforms carry most of the collection burden, which is the part that makes this manageable. Airbnb and Vrbo both operate as registered online lodging marketplaces in Arizona, so on the bookings they handle they collect and remit the state, county and city pieces themselves. You still need your own transaction privilege tax license, you still file, and you claim the marketplace income under deduction code 775, which can mean filing a $0 return in a month where every booking came through a platform. Be aware that the liability stays yours, because the Department of Revenue is clear that the owner is ultimately responsible even where a property manager or a platform does the filing. Take a single direct booking, though, and the whole stack becomes yours to collect and pay over.

Arizona Wide Short-Term Rental Rules

Those rates are the county-specific layer; the framework holding all of it up is state law, and it's worth understanding because it's what keeps your listing legal in the first place.

The core is a matched pair of statutes. A.R.S. § 9-500.39 binds cities and towns, § 11-269.17 binds counties in their unincorporated areas, and both say a local government may not prohibit short-term rentals or regulate them by classification, use or occupancy outside an enumerated list. That list is what Oro Valley and Marana are working from, and it's why their programs look so similar.

So a local government may require a permit or license with the fee capped at actual cost or $250, whichever is less, and it has to grant or deny within seven business days. It may require a 24/7 emergency contact, with a penalty of up to $1,000 for each 30-day period of non-compliance. It may require neighbor notification before the first rental, $500,000 of liability insurance unless the platform supplies equivalent cover, and your license number in every advertisement.

The enforcement side of that same list is where the real numbers live. A local government may suspend a local permit for up to twelve months after three verified violations inside twelve months, or immediately for a felony, a serious injury or death, housing a registered sex offender, or running an unpermitted commercial use out of the property. Aesthetic, waste and parking violations on their own don't count toward the three.

Then the civil penalty ladder runs to $500 for a first verified violation, $1,000 for a second and $3,500 for a third or later within twelve months, or one, two and three nights' rent respectively, whichever is greater. That last clause is the one to sit with, because on a $600-a-night place in the Catalina Foothills the nights'-rent measure overtakes the dollar figure immediately.

One 2026 change belongs in this section because it lands directly on Pima County. A.R.S. § 11-810.01 required every Arizona county to adopt accessory dwelling unit regulations by 1 January 2026, capped rear and side setbacks at five feet, and provided that a county which missed the deadline would have to allow accessory dwelling units on every residentially zoned parcel without limits. Pima County Development Services began reviewing accessory dwelling unit applications on 1 January 2026.

Now, where a unit's certificate of occupancy issued on or after 14 September 2024, a local government is allowed to require the owner to live on the property before that unit can be rented short-term, so check the certificate date before you plan a casita around nightly rates. The county's own letter to the Governor called the new setback rules a way to "put a hotel in every backyard in the state," which tells you how contested this one is locally.

At the legislature itself, nothing passed. HB 2429 would've let cities cap overnight occupancy and stretched the violation-counting window from twelve months to twenty-four, and although it cleared the House 37-14 on 10 March 2026, it never got a Senate hearing and missed its deadlines. The League of Arizona Cities and Towns has said it will keep pushing a bill capping license numbers and setting minimum distances between rentals. As of July 2026 neither preemption statute has been amended, so that whole framework is still the law you're operating under. Neighbouring counties handle the same framework differently, and the Pinal County guide and the Maricopa County guide are the useful comparisons if you're choosing between metros.

Does Pima County Strictly Enforce STR Rules?

Given that the county never built a permit program, "strictly" is the wrong axis. What Pima County enforces is zoning, nuisance and tax, and it does that the way most counties do: when somebody complains.

Complaints about unincorporated property go to the county's Code Compliance program, which the Department of Environmental Quality administers on behalf of Development Services. Its inspectors investigate reported zoning, building and environmental complaints and work with owners to correct them. Nothing about that process is short-term-rental specific, so the realistic exposure is the ordinary stuff: a casita converted without permits, a parking or setback problem, a septic system carrying more people than it was sized for. The county publishes a public portal where anyone can search complaints, violations and permits by address, which cuts both ways when you're the one being looked up.

The penalties behind it come from state law rather than any local rental ordinance. Under A.R.S. § 11-815, a violation of a county zoning ordinance is a class 2 misdemeanor, each day of violation is a separate offense, and a county may set civil penalties up to the maximum fine for that class with the same per-day rule. Counties can also seek injunction, mandamus or abatement. Serve someone with a civil notice of violation and they can't then be criminally charged on the same facts, so in practice this runs as a civil process with a hearing officer and an appeal to the Board of Supervisors.

Inside the towns, enforcement is explicitly reactive, and Oro Valley puts that in writing: staff "will not be proactively inspecting properties and short term rental platforms for compliance," and will instead respond to complaints about missing licenses, missing neighbor notifications or a listing without a town license number. Marana routes the same way, through its licensing office. Watch out for the quieter enforcement channel, though, which is tax. Your license number sits on your listing by statute, the Department of Revenue receives platform-level data on facilitated bookings, and an unlicensed listing advertising nightly stays is a much easier thing to spot than a noise complaint is to prove.

How to Start a Short-Term Rental Business in Pima County

Assuming the rules still work for your situation after all that, the order below saves the most time, mostly because the early steps tell you whether the later ones are worth the effort.

1. Find out which jurisdiction you're actually in. Unincorporated Pima County, Tucson, South Tucson, Oro Valley, Marana and Sahuarita each impose a different combination of license and tax. Everything downstream depends on this answer, so get it from the county's parcel search rather than from a mailing address.
2. Read your covenants and any homeowners association rules. State preemption does nothing against a recorded restriction, and it's the one dead end that no permit gets you past.
3. Get the state transaction privilege tax license. Apply through AZTaxes.gov, expect $12 per location, and note the number down. Two towns and every listing you write will ask for it.
4. Register with the Pima County Assessor under § 33-1902, before anybody occupies the property. Remember the ten-day rule for updating anything that changes afterwards.
5. Apply for the town license, where one exists. Oro Valley and Marana both run programs; budget for the insurance evidence, the emergency contact and the neighbor notification attestation, and expect a decision within seven business days under state law.
6. Do the neighbor notification properly and keep the proof. Marana supplies templates and wants the attestation before your rental start date, which means before your first guest, not after your first complaint.
7. Put your license number in every advertisement. The state license number where there's no local one, the local number where there is.
8. Set up tax before the first booking clears. Confirm what your platform is collecting for your specific address, since Tucson's rate changed in March 2026 and a stale setting there is your liability, not theirs.
9. Check the certificate of occupancy date on any casita you're planning to rent separately, because a date on or after 14 September 2024 can bring an owner-occupancy condition with it.

Who to Contact in Pima County about Short-Term Rental Regulations and Zoning?

Whichever of those steps stalls, four offices handle nearly all of it, and knowing which one owns your question is worth a morning.

Pima County Development Services answers zoning, permits and what's allowed on an unincorporated parcel.

• Address: 201 N. Stone Ave., Tucson, AZ 85701, on the 1st floor of the Public Works Building
• Phone: 520-724-9000, or 520-724-6490 for Building and Site Development

• Address: 33 N Stone Ave, Suite 700, Tucson, AZ 85701
• Phone: 520-724-7400

What Do Airbnb Hosts in Pima County on Reddit and Bigger Pockets Think about Local Regulations?

Notice how short that contact list is next to what a licensing-heavy city would need, because that absence is most of what hosts here end up talking about. What follows is my read of the recurring themes rather than any kind of survey. I read the BiggerPockets threads directly and the rest comes from the county's own public record, and since I didn't read Reddit, nothing here is sourced to it. Do weigh the section accordingly.

• Almost nobody complains about the permitting. In a county where the largest jurisdiction has no rental-specific permit and the county itself has none, there's very little to complain about, and the discussion moves straight past compliance to economics. That's the opposite of what you see in Arizona's regulated resort towns.
• Saturation is the recurring worry, not regulation. On BiggerPockets in June 2023, a broker managing close to 100 Arizona properties wrote that "occupancy dropped like a rock after Q1" and that "there's no more easy money in Arizona," and described operators diversifying into midterm rentals, direct bookings and student housing rather than exiting. That thread is three years old now, and its argument keeps resurfacing.
• Tucson operators talk about the 30-plus-night pivot more than most markets. A Tucson mid-term rental thread started in January 2023 is essentially a networking call among owners running furnished monthly rentals to snowbirds and travel staff, which is a market this county has for structural reasons that have nothing to do with the ordinance book.
• The political temperature is rising, and the county isn't hiding it. The Board of Supervisors approved that letter to the Governor 3-1 rather than unanimously, which is a fair summary of local sentiment: a clear majority wants the power to cap short-term rentals, and a real minority doesn't.

Take that last point seriously when you model a purchase. The rules today are permissive by any national standard, so the risk in Pima County isn't a rule you'll break. It's a rule that doesn't exist yet, backed by a county that has already written down what it would do first. If you want the demand side of that picture before you decide, the Arizona market is where the revenue and occupancy numbers sit.

Frequently Asked Questions

Do you need a permit to run an Airbnb in unincorporated Pima County?

No. Pima County has not adopted a short-term rental permit or license ordinance, and it has no general business license either. Arizona law would let it require one, with the fee capped at $250 or actual cost and a decision due within seven business days, but the county has never taken that option. What you do need is a state transaction privilege tax license and registration with the Pima County Assessor before anyone occupies the property.

How much tax does a Pima County short-term rental pay in 2026?

It depends entirely on the address. An unincorporated property pays 12.05%: 5.5% state transient lodging tax, a 0.55% county transportation excise tax, and a 6% Pima County bed tax that applies only outside town limits. A Tucson property pays 16.05%, because Tucson added a 10% short-term rental class effective 1 March 2026. Oro Valley and Marana come to 14.55%, South Tucson 11.55% and Sahuarita 10.05%.

Can Pima County ban short-term rentals?

Not at present. A.R.S. § 11-269.17 bars counties from prohibiting short-term rentals in unincorporated areas or regulating them by classification, use or occupancy outside a short statutory list, and A.R.S. § 9-500.39 does the same for cities and towns. Pima County's Board of Supervisors voted in November 2025 to ask the legislature to return that authority, and proposed capping existing rentals, but no amendment to either statute has passed.

What happens if you don't register a rental with the Pima County Assessor?

A.R.S. § 33-1902 says residential rental property shall not be occupied if the required owner information isn't on file. The civil penalty is $1,000 plus $100 per month for a newly acquired property that never registers, or $150 per day for an existing property that falls out of compliance. Both are dismissed if you comply within ten days of receiving notice, and a tenant can terminate and recover prepaid rent if you don't.

Which towns inside Pima County license short-term rentals?

Oro Valley and Marana both do. Oro Valley licenses under Ordinance (O)23-01, in effect since February 2023, at an $80 annual fee. Marana charges $60 for a new license, $40 to renew annually and a $10 late fee after 15 days. Tucson requires its ordinary city business license and transient rental tax registration rather than a dedicated short-term rental permit. Unincorporated addresses need no town license at all.

Most places tighten their rules first and argue about it afterwards. Pima County is doing it the other way round, arguing loudly while its rulebook stays about as permissive as any in the country, and that gap is the whole opportunity and the whole risk in one sentence. Whatever you buy here, buy it on numbers that still work if the permissive part ends.
