INTRODUCTION
Cincinnati officially legalized Accessory Dwelling Units (ADUs) in 2023- Ā opening the door for homeowners to add rental income, create multigenerational living space, or increase property value.
A backyard ADU can generate $12kā$24k+ per year in rental income in many Cincinnati neighborhoods.
