So what is an ADU?

An accessory dwelling unit (ADU) is a self-contained living space on your property. It can be attached to your home, built above a garage, converted from a basement, or built as a detached backyard cottage. With Colorado’s updated ADU legislation, it’s now easier than ever to add one — creating more flexibility for homeowners to generate rental income, house family, or increase property value.

Benefits of Accessory Dwelling Units

Why Build an ADU in Denver?

Building an ADU can benefit Denver homeowners in multiple ways. The most important reason depends on what you want it to do!

Rental Income: Offset your mortgage or create steady cash flow.

Family: Give your family a nice, private place to stay.

Home Office or Studio: A separate, quiet space to work or create.

Increased Property Value: Well-built ADUs often significantly raise resale value.

Flexibility: Can be used now for family and later as a rental unit.
