Overview: Are STRs allowed in Mattawa, WA?

Yes—short-term rentals are allowed in Mattawa, Washington. Hosts must obtain a business license (required regardless of rental frequency), comply with zoning, and follow state-level tax requirements. In practice, most STR operation occurs through property management within the Desert Aire community, which has additional homeowner association (HOA) rules and a county-level transient residence program with annual permitting and safety inspections.

Note: This guide distills only the information provided in the linked sources. Where specifics (fees, exact permit workflows, contact details) are not contained in those sources, they are flagged below as needing direct confirmation with the city and county.

How to start an STR business in this market

1. Select a property that aligns with allowed uses

• Confirm zoning allows short-term rentals. This may restrict STRs in certain areas or property types. If buying inside Desert Aire (a gated community with golf and recreation facilities), also verify STRs are permitted under HOA covenants.

2. Secure and maintain business authority

• Apply for and maintain a city business license. Even occasional hosting requires licensing.
• For properties inside Desert Aire, notify the Desert Aire Owners Association (DAOA) of any long-term rental or leasing through the “Landlord & Rental Information Form.” This helps maintain accurate community records.

3. Meet county transient residence (STR) program requirements (Grant County)

• STRs in Grant County typically require a transient residence registration/permit and an annual Fire and Life Safety Operational permit. Grant County is the issuing authority for these permits. Use the county’s “Transient Residence (Short-Term Rental)” and “Annual Fire and Life Safety Operational permit” pages to confirm requirements, timelines, and submittals. Re-inspection and annual renewal are common for such programs.
• Factor local safety and septic considerations into your property readiness. DAOA resources include wildfire readiness information and homeowner septic guidance, both relevant for properties relying on onsite wastewater systems.

4. State-level tax compliance

• Washington State requires sales tax collection on short-term rentals. Register, collect, file, and remit sales tax through the Washington Department of Revenue (DOR). Consult DOR guidance for registration, reporting, and local add-ons that may apply.

5. HOA and community compliance (if applicable)

• If operating within Desert Aire, follow all HOA rules governing structures, amenities, and resident/guest conduct. Failure to comply can lead to fines or access restrictions to community facilities. Use DAOA’s Architectural Application for any improvements or structural changes.

6. Operations and guest experience

• Optimize for seasonality: Mattawa’s demand peaks in summer (outdoor recreation, Columbia River access) and sees a secondary, smaller peak around holidays. Price dynamically, emphasize outdoor amenities, and ensure modern comforts (Wi-Fi, well-equipped kitchens) to attract guests seeking both rustic charm and convenience.
