Executive overview: Yes—short‑term rentals are allowed in Arivaca, AZ. Arivaca is in unincorporated Pima County, and Arizona state law expressly preempts local governments from prohibiting vacation rentals and short‑term rentals. Counties (including Pima) may regulate STRs only for specific purposes such as health and safety, zoning/nuisance, and certain prohibited uses; counties may also require a local regulatory permit/license, contact information for a 24/7 designee, neighbor notification, permit/license number on advertisements, and minimum liability insurance. No separate Arivaca town‑level ordinance is evident in the provided materials; investors should follow Arizona statutes and any Pima County code, rules, and administrative procedures.

How to Start a Short‑Term Rental Business in Arivaca, AZ

1. Confirm eligibility and property fit

• Ensure the property is in unincorporated Arivaca and is a single‑family or one‑to‑four‑family dwelling, or a condominium/cooperative unit, that qualifies as a transient public lodging establishment or owner‑occupied residential home offered for transient use (A.R.S. § 11‑269.17(L)(3)).
• Confirm zoning allows residential use and short‑term rental activity. Pima County may apply use and zoning ordinances to STRs in the same manner as other residential properties. Verify current Pima County zoning or HOA restrictions directly.

2. Obtain Arizona Transaction Privilege Tax (TPT) license (required before applying for a local permit/license)

• Apply with the Arizona Department of Revenue (AZDOR) for a TPT license.
• Use appropriate business activity codes for transient lodging.
• File and remit TPT per AZDOR schedules based on estimated annual tax liability (monthly/quarterly/annual). If you use online lodging marketplaces that collect/remit lodging taxes, use the correct reporting adjustments so you are not taxed twice on platform‑processed revenue; consult AZDOR instructions for the specific deduction/credit for marketplace‑collected tax.
• A valid TPT license is a required submittal for a Pima County STR permit/license if Pima requires one.

3. Secure liability insurance

• Maintain liability insurance in the aggregate of at least $500,000, or demonstrate that your listings are offered exclusively via an online lodging marketplace that provides equal or greater coverage. Keep proof on hand for county review.

4. Designate a 24/7 response contact and local designee (if applicable)

• Provide contact information for the owner or a designee who can respond in person if required by public safety personnel, by phone, or by email at any time of day. Update this information promptly if it changes. Ensure your property management arrangements can meet a 24/7 response obligation.

5. Complete neighbor notification before first offering for rent

• Notify adjacent single‑family properties (direct, side, and diagonal across the street). For multifamily buildings, notify residents on the same floor as the STR. Pima County may also require notifying registered neighborhood associations or HOAs within a specified radius; confirm the radius and process with Pima County.
• The notice must include the STR address, the owner/designee contact information, and—if required—the permit or license number.
• Retain proof of notification (e.g., certified mail receipts) and submit any attestation/affidavit Pima County requires to document compliance.

6. Apply for a Pima County STR permit/license (if required)

• If Pima County requires a local regulatory permit/license, submit a complete application within the county’s application window. Counties must issue or deny within seven business days of receiving the required information and otherwise in accordance with A.R.S. § 11‑1602, and may deny only for specified reasons (e.g., incomplete application, non‑payment of fees, false information, a suspended permit/license for the same property, or certain criminal history/disqualifiers).
• Application fees cannot exceed the county’s actual cost or $250, whichever is less.

7. Display permit/license number on all advertisements

• Include the local regulatory permit/license number on every advertisement (e.g., Airbnb, Vrbo, social media). If Pima County does not require a permit/license, it may instead require displaying the TPT license number on advertisements.

8. Operational readiness and compliance systems

• Prepare safety equipment and a site map for responders (smoke alarms, CO detectors, fire extinguishers) if Pima County requires it as part of the application.
• Establish protocols to prevent non‑residential uses (special events requiring permits, retail, restaurant, banquet, event centers, or similar).
• Build a compliance record‑keeping system to track violations, responses, and communications.

9. Launch and ongoing obligations

• After approval, list the property and operate in full compliance with all state statutes and Pima County requirements.
• Monitor license/permit status, file TPT returns on time, maintain insurance, and keep neighbor/designee contact information current.

10. Optional: check for pending state bills

• Monitor Arizona Legislature for any bills that would modify STR rules. As of the latest available information, HB2740 (2025) was referred to the House Rules Committee and had not become law; do not rely on it unless and until it passes.
