How to choose between them

  • Check the license yourself. Where Illinois or Chicago 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.

Home addition contractors in Chicago: common questions

Do I need an architect for a home addition?

Usually yes, or a design-build firm with in-house design. Additions need stamped structural drawings for the permit in most places, and zoning review on setbacks, height and lot coverage.
