Harrison County, MS Building Safety: Carbon Monoxide Detectors (2026)

01(a) of the Unified Development Code folds carbon-monoxide detection into the same site-plan requirement that covers parking and occupancy. The provision states that "the site plan shall reflect that the unit is equipped with the recommended number of smoke and carbon monoxide detectors," making detector coverage a documented condition of getting the Short-Term Rental Permit and companion Tax Privilege "Business" License rather than a separate inspection ordinance. The section doesn't set a device-per-bedroom count or reference a specific fire code chapter for the number required; it asks the owner to state that the unit meets "the recommended number," which the Zoning Officer reviews alongside the rest of the site plan.

This sits inside the short-term rental rule adopted August 2, 2021 by Ordinance 2011HC186, and it applies only to the unincorporated county, rentals inside Gulfport, Biloxi, Long Beach, Pass Christian or D'Iberville answer to whatever building or fire code each city has adopted, not to this county provision. Because the site plan is part of the permit application the code says must be made by the owner of the property, the owner, not a manager or booking platform, is responsible for certifying detector coverage before the county issues the permit.
