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

Home additions in Port Barrington, IL

Port Barrington began in 1927 as Fox River Valley Gardens, a Fox River village whose original section still holds roughly 200 homes on quarter-acre lots along the man-made Nielsen's Channels; newer neighborhoods — River Walk, Port Barrington Shores, and the early-2000s Deer Grove and Deer Grove North — came as the village grew. Remodeling spans both eras: opening up compact original-section homes near the water and updating kitchens and baths in the newer subdivisions. Homes here draw water from private wells — Lake and McHenry County health departments handle well permits and testing — while sanitary sewer runs through the Northern Moraine Wastewater Reclamation District, so plumbing-heavy projects get planned around both from day one. Near the river, floodplain review shapes additions and lower levels. GS Construction builds that context into kitchens, bathrooms, basement build-outs, additions, and whole-home remodels. Families are served by Wauconda District 118 schools, with Metra's UP-NW line a short drive away at Fox River Grove and Cary.

Port Barrington permits & building codes for home additions

The Village of Port Barrington requires permits for new construction, additions, remodeling, electrical work, HVAC and water-heater replacement, roofing, fences, and even tree removal, all reviewed by the village Building and Zoning Officer. The village spans Lake and McHenry counties, so when a project needs a county permit — such as a health-department well permit or a Northern Moraine Wastewater Reclamation District sewer approval — the approved copy must be presented before the village reviews the application, and the village engineer signs off on any work in the floodplain or floodway before a permit can be issued. GS Construction manages the entire permit process for Port Barrington homeowners, from village application and county coordination through final inspections.
