Littleton adu construction: your questions answered
What does an ADU cost in Littleton?
ADU Construction in Littleton follows greater-Denver pricing of roughly $180,000 – $400,000+. Where your project lands depends on materials, size and whether utilities or structure change. MKN Construction & Remodeling prices your Littleton project as a fixed, itemized written estimate, so the number you sign is the number you pay.
How long should a ADU project take in Littleton?
Plan for 2–5 months of design and permitting followed by 4–8 months of on-site construction. Material lead times and permit review are the biggest schedule factors, so we order long-lead items and file permits while the design is wrapping up.
Who pulls the permits for accessory dwelling units (ADUs) in Littleton?
We do. Homes in Littleton are permitted through the City of Littleton, not the City and County of Denver. We prepare and file the required building and trade permits under our own contract and book every inspection. Like-for-like cosmetic updates often need none, while changes to structure, plumbing, gas or electrical do.
