Licensed In-House Crews

Every carpenter and project manager on our team is fully licensed and trained specifically for residential additions in Chicago. We never subcontract the critical structural work, so quality stays consistent from footings to paint.

02
Permit-Ready Plans

We prepare architectural drawings and engineering packages that speed up city and village permitting. Our familiarity with Chicago's zoning and building departments means fewer delays and faster start dates.

Chicago-Weather Tough

We spec freeze-thaw rated materials, reinforced foundations, and high-R-value insulation designed for Lake Effect winters and humid summers. Your addition stays warm, dry, and energy-efficient year-round.

Client Stories

What Our Clients Say

Homeowners across Chicago trust us to expand their living space with minimal stress and maximum craftsmanship.

"Chicago Home Additions turned our cramped bungalow into a spacious family home with a second-story addition. The crew was punctual, the city permits were handled seamlessly, and the finish carpentry matched our original woodwork perfectly."

James R.
Second-story addition, Lincoln Park

"We needed a heated garage addition before winter and they delivered on time and on budget. The concrete pad, electrical, and roof match our existing home so well that neighbors ask when we bought a bigger house."
