An in-law suite can add value to a home when it creates useful, private, permitted living space that fits the home naturally.

The demand is not random. Pew Research reported that the share of the U.S. population living in multigenerational homes more than doubled from 7% in 1971 to 18% in 2021. (Pew Research Center) The U.S. Census Bureau also reported that multigenerational households made up 7.2% of family households in 2020, an increase from 2010. (Census.gov)

Key questions to ask include:
Permits matter. Louisville Metro states that a building permit is required when an owner or authorized agent plans to construct, enlarge, remodel, or change the occupancy of a building. (Louisville.gov) Louisville’s Land Development Code also allows one attached or detached accessory dwelling unit per single-family dwelling per lot in certain residential districts, subject to standards, including size limits.
