Mississippi Garage Conversion Building Code Compliance Rules

Under Miss. Code Section 17-2-1, jurisdictions enforce the International Residential Code, which classifies converting a garage to a bedroom or living area as a change of use. Converted spaces must meet IRC R304 minimum room sizes, R305 ceiling heights of 7 feet, R310 emergency escape and rescue openings, R314 smoke alarms, R315 carbon monoxide alarms, R303 natural light and ventilation, and energy code insulation requirements. Existing slab heights, headroom, and foundation often require modification. Local zoning rules govern whether conversions are permitted at all and any parking replacement requirements.

Unpermitted garage conversions may face fines, removal orders, refusal of certificate of occupancy, insurance denial, and disclosure requirements at sale that reduce property value.
