Louisiana Code Rules for Garage Conversions

Under La. R.S. 40:1730.28, converting a garage into habitable space triggers full compliance with the IRC chapters adopted by the LSUCC. Owners must provide minimum 7-foot ceilings, light and ventilation, emergency escape and rescue openings, smoke and carbon monoxide alarms, energy code insulation, and fire separation if a portion remains as a garage. In flood-prone parishes, the converted area must also meet the elevation and flood vent provisions of the local floodplain ordinance certified to FEMA. Local jurisdictions cannot waive these construction standards but may impose additional zoning or parking requirements.

Unpermitted garage conversions can result in citations, daily fines under local code enforcement, required reversal to original use, and denial of homeowner insurance claims.
