Gautier, MS Accessory Structures: Garage Conversions (2026)

Garage conversions in Gautier are treated as a change of use within an existing residential structure and are reviewed by the Planning and Building Department (228-497-8000; sankerson@gautier-ms.gov). Because the city enforces the 2018 International Building Code and 2017 National Electrical Code, converted space must meet residential ceiling height, light, ventilation, egress window, smoke-alarm, and electrical-circuit requirements. Gautier sits on the Mississippi Gulf Coast in Jackson County, so structural work is reviewed against the elevated wind loads applicable to coastal Mississippi (ASCE 7 wind speeds adopted with the IBC/IRC) and, where the parcel is mapped in a Special Flood Hazard Area, the city's Flood Damage Prevention Ordinance and FEMA elevation rules apply. Removing a required parking space by closing the garage door opening triggers the off-street parking minimums in Appendix A (Zoning); the conversion plan must show how the dwelling still meets its residential parking ratio, often by adding a driveway pad or carport. A zoning verification, building permit, and likely electrical and mechanical permits are required before work begins.
