Montgomery County, OH Short-Term Rentals: Permit Requirements (2026)

Ohio does not have a statewide short-term rental licensing scheme. R.C. 5739.09 authorizes counties and convention facilities authorities to levy a lodging excise tax on transient guest lodging (stays under 30 consecutive days). Montgomery County levies a 3% lodging excise tax administered by the Montgomery County Convention Facilities Authority and the County Auditor. State sales tax under R.C. 5739.02 is also due on lodging (Ohio state sales tax is 5.75%, plus county/transit add-ons). Within unincorporated Montgomery County there is no county-level STR registration ordinance; STRs are governed by township zoning under R.C. 519. The City of Dayton confirms on its website that it does not currently register or regulate STRs but is collecting data through a vendor (Avenu STR IP LLC) and intends to develop a registration framework in the future. Dayton defines a short-term rental as a residential dwelling offered to the public for stays of fewer than 30 consecutive days in any 12-month period. Other Montgomery County cities (Kettering, Centerville, Oakwood, Miamisburg) each set their own STR rules under R.C. 713. Operators are still subject to general business registration with the Ohio Secretary of State, federal income tax, and any platform-collected lodging tax.
