Home additions in Long Lake, IL

Long Lake has no village hall at all: it's an unincorporated lake community spread across Grant, Avon, and Lake Villa townships, wrapped around the lake it's named for — roughly a third of the area is water. It began as an early-1900s summer-cottage colony, its first cottages arriving as catalog lumber kits at the Round Lake depot, and is now a year-round community of about 3,700. Housing runs from older lake cottages to newer subdivision homes, and our work follows suit: kitchens and baths that make compact footprints live larger, basement finishing, and additions and whole-home renovations that turn a cottage into a modern family house. Plumbing-heavy projects start with the water source — with no water system of its own, an address here may sit on a private well, Fox Lake water, or Round Lake Beach water. Much of the community feeds Gavin School District 37 and Grant Community High School, and the Long Lake flag stop on Metra's Milwaukee District North line runs to Union Station.

Long Lake permits & building codes for home additions

Long Lake is unincorporated, so there is no village building department — remodeling and addition permits go through Lake County Planning, Building & Development in Libertyville, with reviews coordinated across county departments. Parcels on a private well or septic system get a concurrent Lake County Health Department review, and an addition that adds a bedroom or grows the house by more than 50% can require bringing the septic system up to current code. GS Construction manages the full permit path — county application, health-department coordination, and inspection scheduling — for every Long Lake project.
