This update is part of Cary’s broader strategy to create more housing choices for our community. 

What’s Changed? 

With ACT 32, ADUs are now allowed in all residential zoning districts where detached dwellings are allowed, and with increased maximum sizes (depending on the property and primary home size). The updated ordinance also simplifies the rules to make it easier for property owners to build them. While this change increases flexibility, some limitations still apply, such as setbacks and requirements set by homeowners associations or the North Carolina building code. 

This change supports key recommendations in the Cary Housing Plan and the Imagine Cary Community Plan, helping meet residents’ evolving needs while maintaining neighborhood character. New online resources, including a step-by-step guide, make it easier for residents to explore their options.
