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

Home additions in Grayslake, IL

Grayslake grew in rings: an 1895 village core of older homes around the historic Center Street downtown, then a 1990s boom that more than doubled the population and filled in subdivisions like English Meadows, Chesapeake Farms, and the nationally recognized Prairie Crossing conservation community. Those 1990s and early-2000s houses are now 25 to 35 years old — right when original builder kitchens and bathrooms start to feel dated and basements are ready to become real living space, the heart of GS Construction's work. In older homes near downtown, we plan remodels around earlier-era framing and plumbing: the Village runs its own Lake Michigan water and sewer utility, and houses built before the 1960s may still have lead service lines, with a Village cost-share (50% up to $4,500) available through 2026. With three Metra stations on two lines, College of Lake County's main campus, and District 46 and 127 schools anchoring family life, Grayslake homeowners tend to stay and improve — whole-home remodels and additions included.

Grayslake permits & building codes for home additions

Grayslake's Village Code requires building permits for most interior and exterior improvements — kitchen, bath, and basement remodels, electrical and plumbing changes, windows, roofing, and room or garage additions all qualify, with only finishes like flooring and painting exempt. With a complete submittal, the Village's goal is to issue most permits within 7 business days; more complex projects can run 14 to 30 business days. Applications go through the Building Department at Village Hall on Seymour Avenue, and permit fees are even waived for lead service line replacements under the Village's assistance program. GS Construction manages the entire permit process for Grayslake projects, from application and plan submittal through final inspection.
