Supporting Changing Family Needs
14% of Franklin County residents are 65 or older — ADUs give families flexible housing options to support aging parents, adult children, and multigenerational living.
Current Process Too Complex
ADUs are not currently allowed "by right" in Columbus. Homeowners must navigate a costly, complex process just to build a small unit on their own property.
Streamlining for Results
This legislation cuts red tape and reduces upfront barriers, helping residents create more housing options in every neighborhood.
Columbus Accessory Dwelling Units Initiative
Making It Easier for Homeowners to Add Housing Options
With the passage of Ordinance 2526-2025, Columbus has made it easier for residents to add accessory dwelling units (ADUs) to existing residential properties. ADUs are small, self-contained homes that can be attached to a primary residence or built as a separate structure, providing additional options for families who want to live close together, homeowners looking to make better use of their property and residents seeking more flexible housing options.
As part of Columbus Forward, the legislation expands housing choices across the city, supports multigenerational living and creates new opportunities for homeowners to build wealth.
In 2026, the City of Columbus published an Accessory Dwelling Unit Handbook to help residents understand the requirements and process for adding an ADU to their property. View the handbook here.
Key Outcomes & Benefits
Support for Multigenerational Living
ADUs make it easier for families to care for aging parents, accommodate adult children, or help with childcare. These small, independent living spaces let families stay close while maintaining privacy and independence.
Additional Income for Homeowners
When used as rental properties, ADUs can provide homeowners with extra income to help with mortgage payments, property taxes, or other expenses. It's a way to make your property work harder for you.
More Housing Without More Sprawl
ADUs add housing units in existing neighborhoods without requiring new infrastructure or sprawling development. This helps address Columbus' housing shortage while preserving neighborhood character.
Simpler, Cheaper Process
Instead of expensive variance applications and lengthy approval processes, homeowners will have a clearer, more affordable path to adding ADUs. No more guessing about zoning requirements or facing financial risks upfront.
