Summary
In unincorporated Shelby County the Unified Development Code caps cumulative accessory-structure footprint at 75 percent of the principal structure, and sets a 40 percent building-coverage limit for manufactured-home-park residential lots.
The cumulative square footage of accessory structures on any given tract or lot shall not exceed 75% of the total square footage of the principal structure on the same tract or lot except for in the CA district, where no limitation applies.
Full Breakdown
The Memphis and Shelby County Unified Development Code controls how much of a lot may be built upon. Under UDC Sub-Section 2.7.2C, the cumulative square footage of accessory structures on any tract or lot may not exceed 75 percent of the principal structure's square footage on the same lot, except in the CA district where no limitation applies. The UDC also limits the number of accessory structures: no more than one on a residential lot under 6,000 square feet. For manufactured home parks (Section 3.6.3), residential lots may not exceed 40 percent building coverage and nonresidential lots 60 percent, with common open space required. Standard single-family districts rely on minimum setbacks and lot sizes rather than a flat coverage percentage.
Violations & Fines
Building accessory structures whose combined footprint exceeds 75 percent of the principal structure, or exceeding manufactured-home-park coverage limits, violates the UDC. The Division of Planning and Development may deny permits, issue correction orders, and require removal of excess structures.
