Home additions in Chicago, IL

Remodeling in Chicago starts with the city's signature housing stock. 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. These homes reward careful updates: compact original kitchens open up to dining rooms, full basements finish into real living space, and half-story attics hold expansion potential — especially now that Chicago's ADU ordinance, citywide since April 2026, allows basement and attic conversion units on many parcels. One local must-check before kitchen or bath work: the city still has roughly 400,000 lead water service lines, the largest inventory in the nation, and the free Service Line Inventory map shows the material serving any address. GS Construction plans kitchens, bathrooms, basements, additions, and whole-home remodels around these realities, from Edison Park and Norwood Park on the Metra UP-NW line across the Northwest Side.

Chicago permits & building codes for home additions

Chicago building permits go through the city's Department of Buildings, which routes projects by scope: the online Express Permit Program handles most repair work and small improvement projects, renovations that need architectural plans go through the Standard Plan Review Permit Program, and a licensed design professional can fast-track eligible plans through Self-Certification. Structural, electrical, and plumbing work beyond minor repairs requires a permit, and income-eligible long-term senior homeowners can have permit fees waived on 1-3 unit homes they occupy. GS Construction manages the full permit process for every Chicago project — application, plans, and inspection scheduling included.

5 Stars

We worked with Patryk and Greg on a first floor remodel, including our kitchen. We couldn't be happier with the results. I highly recommend working with them. They are very professional and they keep the project moving along. Their workmanship is high quality, too!
