ADU types in the recent set
Housing law — Tennessee
Accessory dwelling units in Tennessee are regulated locally; there is no statewide ADU mandate, so rules vary by city and county.
Tennessee has no statewide upzoning law; residential density is set by local zoning, with Nashville pursuing its own reforms.
Nashville ADU rules
Nashville regulates accessory dwelling units through Metro's detached accessory dwelling unit (DADU) ordinance. A late-2025 overhaul (Ordinance BL2025-1007, effective December 12, 2025) made DADUs allowed by right across the Urban Services District — Nashville's urban core — ending the prior parcel-by-parcel overlay process there; in the outer General Services District, a DADU still generally requires a DADU overlay or an equivalent zoning approval.
Unlike many cities, Nashville retains an owner-occupancy requirement: the DADU and the principal house must be under common ownership, and one of the two dwellings must be owner-occupied. The newer ordinance also restricts short-term rental of DADUs in single-family zones. A DADU is the code-defined detached unit (one per qualifying single-family parcel), with size limits that scale by lot — generally a few hundred up to roughly 1,200 square feet and never larger than the principal structure — plus eave, ridge, and setback standards in Metro Code.
The DADU framework originated with Substitute Ordinance BL2015-1120, which created the original opt-in overlay; the 2025 ordinance is the current controlling law. Note that a DADU permit in Nashville must be pulled by a registered contractor rather than self-permitted.
