"Your Home Additions project deserves the best—we deliver it."

Home additions in Des Plaines, IL

Des Plaines is a postwar boom town — its population nearly quadrupled between 1950 and 1970 as ranches, Cape Cods, split-levels, and bi-levels filled in around a downtown centered on Miner and Ellinwood Streets since the 1870s, while the Cumberland neighborhood mixes 1920s Tudors into that stock. Remodeling here usually means opening up compartmentalized floor plans, rebuilding original bathrooms to the studs, or adding space with an addition or whole-home project. Two local factors shape the work. Most homes get Lake Michigan water through the City's own system, but thousands of service lines are known or suspected lead or galvanized — a city-funded replacement plan has been proposed — so we verify the line before plumbing-heavy remodels. And with the Des Plaines River just east of downtown, we plan basements around flood protection: overhead sewers, backwater valves, and backup sump pumps that can qualify for the City's Flood Rebate Program. Families are served by District 62 schools and Maine West, with Metra UP-NW stops downtown and at Cumberland.

Des Plaines permits & building codes for home additions

The City of Des Plaines requires building permits for remodeling, additions, repairs, and demolition, issued through the Community and Economic Development Department's Building Division. Contractors must be licensed, bonded, and insured with the City before a permit can be issued. If a basement project adds flood-control measures such as an overhead sewer or backwater valve, the City's Flood Rebate Program can reimburse 30 percent of eligible costs up to $2,000. GS Construction manages the full permit process — application, plan review, and inspection scheduling — as part of every Des Plaines project.
