Home additions in Lake Barrington, IL

Lake Barrington incorporated in 1959 to keep zoning in local hands, and the wooded, large-lot character it protected shows in every era of its housing. Barrington Harbor Estates off Kelsey Road dates to the late 1950s; Lake Barrington Shores added 1,317 gated townhomes and condominiums around a 96-acre private lake between 1974 and 1996; and newer subdivisions like the custom Enclave of Heritage Estates and Taylor Morrison's Tallgrass carried building through the 2010s into the 2020s. GS Construction matches the remodel to the era — kitchen and bathroom updates in 1970s–90s Shores units, whole-home renovations of the village's oldest mid-century houses, and basement build-outs and additions on wooded single-family lots. One local reality shapes planning: there is no village-wide water system, so most houses run on private wells and septic, and any project that moves plumbing accounts for Lake County Health Department requirements from day one. Families here are served by Barrington 220 schools, with Metra's UP-NW line in neighboring Barrington.

Lake Barrington permits & building codes for home additions

The Village of Lake Barrington issues its own building permits, with plan review and inspections handled by a contracted third-party building code firm — first residential plan reviews typically take 7–10 business days and can run longer in the spring and summer permitting seasons. Because most homes here rely on private wells and septic rather than municipal service, remodels that add or relocate plumbing may also involve Lake County Health Department review. GS Construction manages the entire permit process for Lake Barrington projects — application, plan review, health-department coordination where needed, and inspection scheduling.
