Summary
Harrison County requires every short-term rental unit's site plan to show the recommended number of smoke and carbon monoxide detectors before the county issues a Short-Term Rental Permit. The rule sits inside UDC § 834.01(a), the same section that caps occupancy at 10 or 16 guests and ties enforcement to the county's Cease and Desist process.
The site plan shall reflect that the unit is equipped with the recommended number of smoke and carbon monoxide detectors.

Violations & Fines
A Short-Term Rental Permit issued without the required smoke and carbon monoxide detectors, or any other § 834.01 condition, triggers a Cease and Desist Order under UDC § 1409. Continued, knowing violation of the Unified Development Code is a misdemeanor under § 1409.03: a fine of up to $100 per offense, court costs added, and each day the violation continues after notice counts as a separate offense.
