Garage Conversion Cost in Mississippi

Converting a garage into a living space is a popular way for Mississippi homeowners to add value and square footage without the high cost of a traditional home addition.

Whether you are creating a mother-in-law suite in Jackson or a rental unit in Gulfport, this guide outlines the critical phases, costs, and local considerations for a successful conversion.

Frequently Asked Questions

How much does a garage conversion cost in Mississippi?

On average, a full conversion into living space in Mississippi ranges from $73 to $136 per square foot. A basic bedroom might cost $15,000 to $25,000, while a studio with a kitchen and bath can exceed $50,000.

Do I need a building permit for a garage conversion in MS?

Yes. Most Mississippi municipalities require building, electrical, and plumbing permits. This ensures the space meets International Residential Code (IRC) standards for habitable rooms, including ceiling height and emergency egress.

What are the insulation requirements for MS?

In Mississippi (Climate Zone 3), you typically need R-13 to R-15 insulation in the walls and R-30 to R-49 in the ceiling. Using a radiant barrier is highly recommended to combat the intense Southern sun.

Will a garage conversion increase my property taxes?

Yes. Since you are increasing the 'heated and cooled' square footage of your home, your local tax assessor will likely revalue your property, leading to a modest increase in annual property taxes.
