Summary
Hamilton County flatly prohibits renting an accessory dwelling unit as a short-term vacation rental. Section 305 of Resolution No. 924-23 bars both detached and attached ADUs from STVR use, closing off the most common workaround for turning a new accessory unit into an investment listing rather than housing.
305 - Short Term Vacation Rentals 1) The detached or attached ADU cannot be used or rented for the use of a Short-Term Vacation Rental.
Full Breakdown
' The prohibition covers both structural types the resolution recognizes, so converting a garage or building a stand-alone unit does not open a path to nightly or weekly rental use. The restriction sits alongside Section 304's owner-occupancy requirement, which already requires the property owner to live in either the principal house or the ADU as a permanent residence; together the two sections rule out using a newly permitted ADU as a short-term-rental income property. Section 301's stated intent is to add long-term housing supply and small-scale infill in a manner that keeps the residential character of unincorporated neighborhoods, and the STVR ban is the mechanism that keeps ADUs from becoming visitor accommodations instead.
The rule applies to every ADU permitted under Resolution No. 924-23 regardless of zoning district, other than the A-1 Agricultural District where ADUs are not permitted at all, and regardless of whether the unit is newly built or a conversion of an existing accessory structure or non-conforming detached structure under Section 303. There is no seasonal, occasional-use, or owner-present exception written into Section 305; the text bars the STVR use outright rather than capping the number of rental nights.
Violations & Fines
Renting a Hamilton County ADU on a short-term or nightly basis violates Section 305 outright, with no exception for occasional or owner-present rentals. A property owner found operating an ADU as a Short-Term Vacation Rental is out of compliance with Resolution No. 924-23 and subject to code enforcement by the Hamilton County Building Inspections Office, the office charged with administering the ADU standards under Sections 306 and 307.
