ADU Construction in Colorado
An Accessory Dwelling Unit (ADU) is a separate living space located on the same property as a primary residence. ADUs can provide flexible space for family members, guests, long-term living arrangements, or other permitted uses.
Colorado's ADU laws and local requirements can vary by jurisdiction, and projects must still meet applicable zoning, building, and permitting requirements. Denver maintains its own building and zoning requirements, while state law has also expanded ADU opportunities in qualifying jurisdictions.
K&D Development can help coordinate the construction process and the many trades required to complete an addition or ADU.
Home additions can create space for:
- Primary bedroom suites
- Additional bedrooms
- Bathrooms
- Family rooms
- Home offices
- Expanded kitchens
- Guest spaces
- Mudrooms
- Attached living areas
