What is an ADU and how can it be used?

An accessory dwelling unit is a self-contained living space located on the same property as a primary home and can be used for guests, family members, rental income, or flexible long-term living.

Can you build a detached ADU in Colorado Springs?

Yes, detached ADUs are allowed in many areas of Colorado Springs, but zoning, lot size, and design requirements vary and should be reviewed early in the process.

How large can an ADU be in Colorado Springs?

ADU size is regulated by local zoning and code requirements, which determine maximum square footage, height, and setbacks based on the property.

Does an ADU include a full kitchen and bathroom?

Yes, a code-compliant ADU typically includes a full kitchen, bathroom, sleeping area, and independent utilities to function as a complete living space.

How long does it take to build a detached ADU?

The timeline depends on permitting, design complexity, and construction scope, but most detached ADU projects take several months from approval to completion.
