📖Detailed Analysis

No statewide ADU law - entirely local control with generally very restrictive approach. Described as having 'some of the most restrictive zoning laws in the country, making it difficult to build ADUs in most areas of the state.' Local regulations are set by municipalities and counties individually. The absence of statewide mandates has created a diverse but generally restrictive foundation where ADU zoning rules are largely at the discretion of local governments. Most jurisdictions either prohibit ADUs or have severely limiting requirements. Mississippi represents one of the most challenging states for ADU development in the nation.
