Chicago Home Additions is a family-owned general contractor. We design and build home additions, room expansions, ADUs, and full kitchen remodels across Chicago.
From bump-outs to full second stories, we expand Chicago homes without sacrificing style or structure.
We pour frost-depth footings, tie into existing foundations, and frame with engineered lumber to support second-story loads. Each addition is wrapped in ZIP System sheathing, insulated to R-21 walls and R-49 roof, then matched to your existing siding and brick for a seamless look. Finished interiors include hardwired smoke detection, dedicated HVAC zones, and permit-ready egress windows.
Need one more bedroom or a bigger family room? We pop out gable walls, cantilever floors, or extend foundations to add exactly the footage you need. Every structural calculations ensure load paths stay safe while our crews keep your family living in place during work. Final punch list includes trim that matches existing profiles and paint blended on site.
Turn your garage or unused yard into a rentable unit or in-law suite. We pull Chicago accessory dwelling unit permits, run separate electrical meters, and install mini-split HVAC systems for code-compliant privacy. Kitchenettes and full baths are roughed in early so drywall and finishes flow fast. Every ADU meets fire separation and egress standards before final inspection.
Knock down walls or add square footage to create the kitchen you actually cook in. We re-route gas lines for pro-style ranges, recess LED cans on dimmers, and install soft-close plywood cabinets rated for Chicago humidity. Quartz counters are templated after cabinets to guarantee zero gaps. Tile backsplashes are sealed with color-matched grout for easy cleanup.
Lower-level space becomes a legal living area with egress windows, sump pump backup, and moisture-sealed walls. We install LVT floors over insulated subfloor panels and run dedicated circuits for home theaters. Permits cover HVAC extensions and smoke alarms tied to the main panel.
From single-car tuck-ins to three-car structures with storage lofts, we pour new slabs, frame walls, and install insulated garage doors with Wi-Fi openers. Electrical includes 220V for EV chargers and exterior sconces for safety. Siding and roofing match your home for curb appeal.
We measure your space, discuss goals, and sketch three layout options on the spot. You leave with a clear budget range.
A written line-item quote with timeline and allowances arrives within 48 hours. We adjust until it fits your budget.
