Note: City-specific short-term rental ordinance details for Watertown (WI) were not available in the provided source. This guide therefore details Wisconsin state-level requirements, plus Jefferson County/Dodge County public health requirements that apply to STRs in Watertown. If Watertown later adopts local STR rules, they would sit atop these baseline requirements. Always verify with the local authority before opening.

1) Overview: Are short-term rentals allowed in Watertown, WI?

• Explicit answer: Yes. Short-term rentals (e.g., Airbnb/Vrbo) are allowed in Watertown, WI under Wisconsin state law.
• Wisconsin defines STRs as “tourist rooming houses” (TRH). The state does not prohibit TRH operations, though it does require licensing and health/safety compliance.
• No local ban was identified. If Watertown enacts local STR rules later, those would add to (not replace) state/county requirements.

Practical implication: You can legally operate an STR in Watertown if you obtain and maintain the required state and county permits, register for room tax, and comply with health/safety codes.

2) How to start a short-term rental business in Watertown, WI

Step-by-step sequence (typical, but verify dates and renewals with each authority):

1. Confirm zoning and property details

• Confirm the property’s zoning allows transient lodging. In Wisconsin, TRHs may be permitted differently by district; many jurisdictions allow TRHs in residential zones as an accessory or conditional use, but local zoning still applies. Confirm with Watertown’s planning/zoning office.

2. Obtain state-level licensing (DATCP)

• Apply for a Wisconsin Tourist Rooming House (TRH) license through the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP).
• Properties with 1–4 rooms: TRH license. Properties with 5+ rooms: State Hotel license.
• Licenses are annual and run from July 1 to June 30. Expect a license fee and a pre‑inspection fee.

3. County health licensing and inspection

• Apply for a county Tourist Rooming House (TRH) license through the public health department for the county where the property is located (Jefferson County Public Health or Dodge County Public Health). This typically includes a pre‑inspection and annual licensing.
• Comply with state/local health and safety codes (smoke/CO detectors, fire extinguisher, maximum occupancy, sanitation, water/wastewater, etc.). Maintain a guest register.

4. Register for taxes

• Sales tax: Register with the Wisconsin Department of Revenue for sales/use tax and any seller’s permit needs.
• Room tax: Register with the City of Watertown (and/or county, depending on local procedures) to obtain a room tax account and receive filing instructions.

5. Insurance and safety setup

• Maintain liability and property damage insurance appropriate for short‑term rentals.
• Install and maintain required safety devices and post emergency information as required by code.

6. Operational readiness and recordkeeping

• Prepare house rules, welcome materials, and an on‑call contact. Maintain guest registry and STR records (reservations, payments, complaints) as required by local or county rules.

7. Renewals and ongoing compliance

• Track renewal dates for DATCP license (July 1–June 30), county health license (annual), and room tax registrations/permits (annual in many jurisdictions).

Recommended first contacts (see Section 6 for details and links):

• DATCP (state TRH/Hotel licensing)

• City of Watertown Finance/Clerk (room tax registration)

4) Specific regulations (state, county, and—where applicable—city)

Wisconsin state

• Definition: Short‑term rentals are “tourist rooming houses” when lodging is offered to tourists/transients for pay.
• No statewide ban on STRs. DATCP licenses TRHs (1–4 rooms) and Hotels (5+ rooms).
• Local authorities can set rules; Wisconsin law has been interpreted to prevent municipalities from limiting STR rental days below 180 days in a 365‑day period.

County (Jefferson or Dodge County public health)

• County TRH license required, typically with an annual pre‑inspection and renewal.
• Standards commonly include smoke/CO detectors, fire extinguishers, safe egress, sanitation, water/wastewater, posting requirements, and maintaining a guest register.
• Inspections may occur before issuance and on a routine basis thereafter.

City of Watertown

• A local room tax registration/permit is typically required to collect and remit lodging taxes on transient stays.
• Zoning: Confirm that STRs are permitted at your address/district as an accessory or conditional use, and that occupancy/parking standards are met.
• No city-specific STR ordinance details were found in the provided sources. If the City later adopts an STR licensing/operations ordinance, follow those rules as well.

Taxes (state and local)

• State sales tax applies to many STR transactions. Register with the Wisconsin Department of Revenue to collect and remit applicable sales/use taxes.
• Local room tax (lodging tax): In Wisconsin, municipalities and counties often impose a transient room tax on lodging charges. Watertown’s room tax (and any county lodging tax) must be registered for and remitted via the City Finance/Clerk and/or County Treasurer per local practice.
• Occupancy and income reporting: Short‑term rental income is taxable for federal and Wisconsin income tax purposes. Maintain complete records.
