Housing - As introduced, encourages municipalities to study and assess housing affordability and inventory availability, and to adopt a pattern book for purposes of encouraging the construction of medium-density housing. - Amends TCA Title 6; Title 7 and Title 13.

HB 2340 encourages Tennessee municipalities to study housing affordability and inventory by requiring them to: (1) conduct a detailed housing stock inventory, (2) assess current/future housing needs based on demographics and income gaps, and (3) create a pre-approved "pattern book" of medium-density housing designs. This pattern book would include standardized floor plans, building layouts, and streamlined permit processes for "missing middle" housing - mid-sized developments between single-family homes and large apartment buildings (under 12 units). The bill directly affects local governments and developers by aiming to make housing construction more efficient and affordable within existing neighborhoods. It does not mandate adoption but provides a framework for communities to address housing shortages through planning. The bill is currently pending committee review in the Tennessee General Assembly.
