In the recent state legislative session, a bill allowing local governments to adopt building code amendments for three- and four-family homes passed the General Assembly, paving the way for local building code amendments made by Memphis and Shelby County in 2022 to move forward. This is significant legislation for reforms recommended by the Joint City-County Housing Policy Plan to help ease the cost of construction for triplexes and quadplexes. Thanks to the bill’s sponsors and supporters in helping make this possible.
Beginning July 1, 2024, DPD will again allow three- and four-family homes to be permitted as residential construction and will enforce the local amendment to the extent allowed by state law. This means builders can trade out sprinklers for increased fire-rated separations between units as a means of compliance.

These changes complement amendments to the Unified Development Code (UDC) adopted in April 2023 that allow for more housing options recommended by the Housing Policy Plan. The following changes—in conjunction with the newly passed state legislation—will help to unlock more housing opportunities in Memphis:
- Cottage-style homes now allowed in the R-6 Single Family district on lots of 30-35’ width and 3,000 square feet and reduced minimum lot size and width for cottage-style homes in the Residential Urban districts.
- Accessory dwelling units (ADUs) now allowed on residential lots as small as 7,000 square feet.
- Townhouses now allowed along major roads in the RU-1 (duplex) district.
- Stacked townhouses and small multifamily (3-6 units) eligible for special use permit at corners and on major roads in the RU-1 (duplex) district.
In addition to creating more opportunities for housing diversity in the RU-1 district by adding options for townhouses, stacked townhouses, and small multifamily, these changes represent a 117% increase in lots where cottage houses are now allowed and 79% increase in lots where ADUs are now allowed.
