Home additions in Chicago, IL
Expanding a home in Chicago often means navigating the architectural legacies of its pre-war housing stock, from the compact footprints of brick bungalows to the multi-story configurations of two-flats. Many homeowners seek to add living space without sacrificing the historical character of their property, especially when original layouts offer limited room for modern family needs. Common additions include rear extensions to expand kitchens and family rooms, or second-story build-outs that transform attic spaces into full bedrooms and bathrooms. These projects frequently involve integrating new construction with existing brick or stone facades, requiring careful material matching and structural planning. The goal is always a seamless blend, enhancing functionality while respecting Chicago's unique urban fabric.
What Chicago homeowners ask for
Chicago homeowners frequently request multi-story rear additions to expand living areas, especially for more spacious kitchens or dedicated family rooms on the first floor, and additional bedrooms or bathrooms above. Another common request involves expanding the footprint of smaller bungalows and two-flats to create ground-level primary suites or larger entertainment spaces, often pushing out towards the rear lot line.
About Chicago
Remodeling in Chicago starts with the city's signature housing stock, which rewards careful updates. Roughly 80,000 brick bungalows — nearly a third of Chicago's single-family homes, built between 1910 and the mid-1930s — form the Bungalow Belt through neighborhoods like Portage Park, Jefferson Park, and Norwood Park, joined by greystones and classic brick two-flats.
In Irving Park's Villa District — 126 Prairie- and Craftsman-influenced homes across seven blocks, largely built 1907–1925 — exterior work needs approval from the Commission on Chicago Landmarks before the Department of Buildings will issue a permit, so we sequence design review ahead of construction dates. Citywide, any building rated red or orange in the Chicago Historic Resources Survey carries a hold of up to 90 days on demolition permits under the 2003 Demolition-Delay Ordinance, which matters whenever a project weighs gut renovation against replacement. And under the Northwest Side Preservation Ordinance, demolition surcharges in the designated 606-area blocks of Logan Square, Avondale, Hermosa, Humboldt Park, and West Town rose in October 2024 to $20,000 per unit and $60,000 per building — economics that push owners of older multi-unit buildings toward the deep renovations we favor anyway.
For additions in Irving Park's Villa District, the Prairie- and Craftsman-influenced homes built 1907–1925 require Commission on Chicago Landmarks approval for exterior work before permits are issued, necessitating early design review. Properties rated red or orange in the Chicago Historic Resources Survey face a demolition permit hold of up to 90 days, influencing decisions between gut renovation and replacement. The Northwest Side Preservation Ordinance's demolition surcharges in the 606-area blocks of Logan Square, Avondale, Hermosa, Humboldt Park, and West Town encourage deep renovations over replacement for older multi-unit buildings. Chicago's ADU ordinance, citywide since April 2026, supports basement and attic conversions, offering expansion potential within existing footprints. We check each address against the landmark district map and Historic Resources Survey rating to understand district-level rules that impact project budgets and timelines.
Home additions in Chicago trigger structural, electrical, and plumbing inspections throughout the construction process, requiring a Standard Plan Review Permit. GS Construction & Remodeling manages the complete permit application process, including plan submission and coordinating all necessary inspections with the Department of Buildings.

I cannot say enough good things about GS Constructions / Greg and Patryk Szady. From the start, their proposal and cost estimate was broken down, item by item, which most contractors don't do. It allowed us to alter our project to fit our budget. Patryk also took the time to explain costs to us and help us get what we wanted for the price we could afford. Once we hired GS, they kept to their timeline, and they focused on our project. Each day we knew when to expect workers (who came on time!) and at the end of each day, we could see real progress. The crews that came to do the work were courteous, respectful of our space, and they cleaned up after themselves. Patryk and Greg didn't just show up once or twice; they were there throughout the project, and were alway helpful in answering questions, addressing concerns, and making it feel like my project was their main focus. Most importantly, the finished product was beyond our expectations. Patryk and Greg really pay attention to detail and are willing to go the extra mile to make things perfect. From exact tile or light placement, to thinking about how cabinets will sit near a doorway, to vent color, they thought of and addressed issues I hadn't even considered, and they made it look perfect, even when that meant more work for them. When I picked a paint color I ended up not loving, they offered to repaint even though it was my mistake. When I picked a wall mounted faucet known for being difficult, they spent hours trouble shooting water pressure and placement in order to get it just right. When the project was all done, Patryk and Greg followed up a few weeks later to make sure we were happy, and come back and address small punch list items that we realized only after living in the space again. It is this kind of attention to satisfaction and attention to detail that is rare to find in this industry, and it makes Patryk and Greg an absolute pleasure to work with. I have recommended them to others we have been equally happy. TL;DR: GS Construction was on time and on budget, and their prices are competitive and fair. Their work was absolutely beautiful, and we couldn't be more pleased. After this experience, I honestly would not use anyone else. I will be a returning customer for life.
