Fox River Grove permits & building codes for home additions
Fox River Grove asks homeowners to check with the Building Department at Village Hall (305 Illinois Street) before making any interior or exterior changes, and remodeling that involves structural, electrical, plumbing, or HVAC work requires a permit. Simple like-for-like replacements such as re-roofs, siding, water heaters, and furnace or AC swaps can be issued over the counter, while additions and larger remodels go through Building Department review before a permit is issued. GS Construction manages the entire permit process for your Fox River Grove project, from application through final inspection.
How your Fox River Grove project runs
ProcessThe same six stages on every job — free in-home estimate through warranty.
Free in-home estimate
Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.
Itemized scope & contract
Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.
Design & selections
Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.
Permits & scheduling
We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.
The build, owner-supervised
Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.
Walkthrough & warranty
We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.
Testimonials
Your Neighbours in Fox River Grove Love Us
Real reviews from homeowners. Ask us for live phone references.
Having done a fairly large amount of “research” online I concluded that it was time to get an excellent contractor team and not second rate. GS is A + excellent. From bottom to top, their people care about doing the right thing, they are active listeners who ask for feedback, and have a very positive attitude in achieving excellence in the little matters which leads to big beautiful renovations. The difference between ordinary and extraordinary is that little extra, said a prominent fb coach, and its true in renovations. Greg Szady and Patryk Szady have high quality people and actively work with my selected and excellent designer Jenn Peterson to put my first floor into the 21st century and beyond my expectations. The designer selected very high quality materials and Patryk and Greg delivered excellent renovations installations and detail. Kudos especially to GS flooring experts because everything transformed beautifully. No one has paid me for this review or told me what to say.
