Pearl, MS Accessory Structures: Garage Conversions (2026)

Pearl regulates garage conversions through two layers. First, the Pearl Zoning Ordinance adopted November 3, 2020 controls use. Section 407.06(c) provides that "No accessory building may be used as living quarters," which prohibits turning a detached garage into an apartment, guest house, casita, or in-law suite on a residential lot. Section 407.06(a) defines an accessory building as a subordinate building on the same lot as the main building, and Section 401.05 limits accessory buildings to 10% of the rear yard and 20 feet in height. Attached garages are part of the principal dwelling and may be converted to additional living space within the same single-family unit, but the conversion cannot create a separate dwelling unit. Second, the conversion is regulated work under Chapter 8 (Buildings) of the Pearl Code of Ordinances and triggers a building permit from the Office of Community Development at 2420 Old Brandon Road (Building Inspector 601-932-3528). Mississippi has adopted statewide residential building, mechanical, plumbing, electrical, and energy codes (IRC-based) that apply to the conversion: minimum ceiling height, egress windows in any new sleeping room, smoke/CO alarms, insulation, heating, and ventilation. Off-street parking lost to the conversion may need to be replaced under the underlying zoning district's parking minimum; confirm with Community Development before starting work.
