FAQ

Home Additions & ADU Builds Denver — Questions

How much does a home addition cost in Denver?

Every home addition is priced to scope — size, materials, and condition all matter. That's why we give a free, no-obligation estimate after seeing the space, so the number is real, not a guess. Ask about our $500 remodel credit when you book.

How long does a home addition take?

Additions and ADUs run 6–18 months depending on scope and permitting. We give you a written schedule up front and Adrian oversees the timeline personally so it stays on track.

Are you licensed and insured to work in Denver?

Yes. AD's Construction LLC is a licensed Class C contractor, BBB accredited, and carries $1M–$2M general liability insurance. You're covered from day one, and we pull the proper Denver permits where required.
