How to choose between them

  • Check the license yourself. Where Texas or Dallas 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 Dallas: 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.
