Broomfield adu construction: your questions answered
What does an ADU cost in Broomfield?
ADU Construction in Broomfield 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 Broomfield 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 Broomfield?
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 Broomfield?
We do. Homes in Broomfield are permitted through the City and County of Broomfield, 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.
