How to choose between them
- Check the license yourself. Where Michigan or Detroit licenses this work, the licensing board's own lookup confirms a license number in a minute. Do it before you sign, not after.
- Get three bids on the same scope. Written down, split into labor, materials, allowances and anything structural. Most people compare a total against a total and end up choosing between two different projects.
- Ask what is not included. Permits, debris removal, fixture and finish allowances, and repairs after demolition are the four that turn a cheap bid into an average one.
- Never pay a large deposit up front. A deposit to order materials and hold a start date is normal. Half the total before anyone shows up is not.

ADU builders in Detroit: common questions
Can I build an ADU on my lot?
It depends on your city and state. California, Oregon and Washington have state laws that make ADUs allowed on most single-family lots. Elsewhere it is set by local zoning, so check lot size, setback and owner-occupancy rules with your city first.
