Building Chicago Homes Since 1999

Chicago Home Additions was founded in 1999 with a straightforward purpose: to give Chicago homeowners a licensed, reliable contractor they could trust with one of the most significant investments they'd make in their property. Over the past 25-plus years, we've built home additions, room additions, and garage additions across the entire city, from Logan Square to Beverly, from Lincoln Park to Bridgeport.

Every member of our team is licensed, fully trained, and brings real experience to each project. We don't use day laborers or unfamiliar subcontractors. When you hire Chicago Home Additions, you get the same crew from groundbreaking to final inspection, managed by project leads who know Chicago's building codes and permit requirements inside out.

With a 4.8-star Google rating and a track record of completed, permitted builds spanning more than two decades, we've built our reputation one addition at a time. We work on referral as much as anything else, and that tells us everything about what matters most: doing the job right the first time.

Established 1999

"When we started this company, the goal was simple: build additions that look like they were always part of the house, handle every permit ourselves, and never leave a homeowner guessing about the schedule or the price. That standard hasn't changed in 25 years."

How We Work

Three principles guide every project we take on in Chicago.

Craft Above All

We measure twice and cut once, every time. The quality of our framing, insulation, and finish work determines how an addition holds up over decades, and we take that responsibility seriously on every project we accept.

Full Accountability

Licensed contractors carry the legal and professional responsibility for the work they put their name on. We keep that responsibility entirely in-house, never handing your project off to third-party crews who answer to a different standard.

Honest Pricing

We write detailed fixed-price estimates and hold to them. Change orders exist only when a homeowner requests something outside the original scope, never because we missed something in our initial assessment or underestimated materials.
