Note on scope: No city-specific STR ordinance for Hamersville is provided in the sources. Hamersville lies within Williamsburg Township and Brown County, Ohio. Where municipal rules are absent, STRs must comply with township zoning and county/state health and lodging tax requirements. Use the Milford, Ohio ordinance only as an illustration of what other municipalities in Clermont County have adopted; it does not apply in Hamersville.

1) Overview: Are Short-Term Rentals Allowed in Hamersville, OH?

• Explicit answer: Yes—short-term rentals appear to be permissible in Hamersville provided the property is in a zoning district that allows the use (e.g., certain commercial districts) and the operator obtains the applicable county/state registrations and pays lodging taxes. If the property is in a purely residential district, STRs may be prohibited or require a zoning variance depending on local interpretation.
• We do not have a city-level ordinance for Hamersville or Williamsburg Township. County and state regulations still apply:
  • Brown County Lodging Facility License (Ohio Department of Health rules).
  • Ohio Transient Guest Registration and fire/life safety compliance (registration, fire extinguishers, carbon monoxide alarms, and posted egress plans).
  • Brown County lodging tax obligations.
• Market presence: VRBO lists multiple short-term rentals in and around Hamersville, indicating an active STR market.

2) Zoning Context: Where STRs Are Most Likely Permissible

• Williamsburg Township (applies to Hamersville addresses): We found a Planning Commission staff report (ZC25-01) that describes B-2 General Business District permitted uses, including “Conference Center, Assembly Hall, or Banquet Facility.” STRs are not specifically listed; lodging uses in commercial districts are often treated as permitted or conditionally permitted lodging uses.
  • In practice, an STR in a general business zoning context (e.g., a standalone cabin or lodge structure) is more likely to be compliant than an STR in a residential district (e.g., a standard single-family home in an R district).
  • If the property is in a residential district, seek a zoning determination from the township zoning inspector before proceeding.

Zoning excerpt for reference (Williamsburg Township, Table 5-1):

• B-2 General Business District permitted uses (select examples):
  • Conference Center, Assembly Hall, or Banquet Facility (by-right).
  • Other general commercial uses and services (see official zoning resolution).
• Site Development Standards for Non-Residential Districts (Table 7-2):
  • Minimum lot size: 1 acre
  • Front yard setback: 50 ft
  • Side/rear yard setbacks: 50 ft (adjacent to residential), 35 ft (adjacent to non-residential)
  • Maximum building height: 50 ft

Important caveats:

• These zoning references come from staff reports; confirm the definitive Williamsburg Township Zoning Resolution for any use-specific limits and to determine whether “lodging” or “transient accommodations” is a permitted or accessory use in the specific district and parcel.

3) Starting a Short-Term Rental Business in this Market

Use the following sequence to reduce risk and ensure compliance:

1. Confirm zoning and land use

• Verify your address is within Williamsburg Township.
• Check whether the subject parcel is in a district that allows lodging/conference/banquet uses or other commercial lodging operations.
• If there is any doubt (especially in residential districts), request a written zoning determination from the township.

2. Ensure access and utilities feasibility

• The Williamsburg staff report notes sewer availability is not obvious in the area and that onsite wastewater treatment may be required. Confirm septic or sewer arrangements with Brown County.
• Confirm access, ingress/egress, and any easements that may affect guest safety and operations.

3. Establish county/state lodging compliance

• Apply for a Brown County Lodging Facility License (ODH rules apply).
• Register with the Ohio Department of Commerce/Health for transient guest registration.
• Comply with fire/life safety requirements:
  • Adequate egress plans posted.
  • Carbon monoxide alarms where applicable.
  • Fire extinguishers on each level.
  • Smoke alarms as required.

4. Implement lodging tax administration

• Register for Ohio’s Lodging Tax and any applicable county lodging taxes (see contact section for Brown County Auditor). Collect, report, and remit taxes on all bookings.

5. Align operations with best practices

• Secure adequate insurance coverage appropriate for short-term lodging.
• Follow posted capacity limits and guest policies to ensure safety and neighbor relations.
• If considering special events or assembly hall functions, confirm alignment with permitted uses and any noise/parking controls.

4) Required Documents, Permits, Licenses, and Guidelines

At minimum, plan to obtain and maintain:

• Zoning verification
  • Written zoning determination/land use confirmation from Williamsburg Township.
  • If in a commercial district and operating as lodging or related commercial accommodation, ensure no conditional use approval is needed.
• Health and lodging permits
  • Brown County Lodging Facility License (under Ohio Department of Health regulations).
  • Ohio transient guest registration, including documentation of compliance with fire/life safety and posted egress plans.
• Tax registrations
  • Ohio Lodging Tax registration and monthly/quarterly filings.
  • Brown County lodging tax registration and filings (contact Auditor’s office for rate and filing cadence).
• Operations materials (recommended)
  • Guest information packet (emergency contacts, house rules, evacuation map).
  • Occupancy and capacity documentation.
  • Safety equipment logs (CO/smoke alarms, extinguishers).
  • Photography and marketing plan to validate that occupancy stays below any applicable thresholds or neighbor-distance rules if later adopted.

Note: If your property is in a purely residential district, STR operation may be prohibited or require a variance; confirm with the township before applying for any lodging permits.

5) Specific Regulations: City, County, and State
