Forest Park permits & building codes for home additions
Forest Park requires a building permit before work begins on most remodeling — structural alterations, moving or adding plumbing fixtures, electrical panel or wiring changes, new windows, roofs, and decks — while like-for-like cabinet swaps, countertops, flooring, and painting are exempt. Contractors must hold a village job license and carry $1,000,000 in liability insurance naming the Village of Forest Park plus a $10,000 surety bond, and electrical and plumbing work each require separate permits. Remodel inspections run in a fixed sequence — rough plumbing with a pressure test, rough electrical, rough framing and insulation, then finals — each on 24 hours' notice to the Building Department at 517 Desplaines Avenue. GS Construction manages the full permit process, from application and insurance paperwork through the final inspection sign-off.

I cannot say enough good things about Greg & Patryk and their team! One of my biggest hesitations about doing such a large project was knowing how hard it is to find a reliable contractor who would give us top quality work at a reasonable price. GS Construction exceeded our expectations in all areas! Our first floor remodel (kitchen renovation with wall removal, half bath remodel, new hardwood floors, updated laundry room) was completed right on schedule. Their attention to detail is amazing, often fixing or adjusting things that I didn't even notice. Their team was a pleasure to have in the house, all were so respectful and patient with our family as we mostly worked from home through the construction. The quality of work from their entire team (carpenters, plumbers, hvac, and painters) was well worth the price. We are beyond thrilled with our updated house! I would recommend GS in a heartbeat and will definitely call on them when it is time to update the rest of the house.
