What Is an ADU?

- Attached (added to the primary home)
- Converted (like turning a garage into a living space)

However, homeowners must follow certain regulations regarding size, height, setbacks, and zoning. For example, detached ADUs can be up to 1,200 sq. ft., with a minimum 4-foot setback from property lines. All projects require permits from the
