Lexington-Fayette County, KY passed an ADU bylaw in 2021. Following a recommendation in the 2018 Comprehensive Plan, Lexington proposed ADU legislation in 2019. The legislation was considered bold by ADU advocates, largely due to allowance for attached and detached ADUs, a lack of owner-occupancy or parking requirements, and reasonable site planning requirements. The proposal received push-back due to a lack of rental registration (and concerns about code compliance); the potential for overcrowding; a lack of design, owneroccupancy, or parking requirements; fears about short-term rentals; and other frustrations about capacity and neighbors wanting more control on permitting. The final legislation was a compromise by only allowing detached ADUs in existing structures (like garages), adding owner-occupancy requirements, and clearer (but still limited) design standards.
