Hawthorn Woods permits & building codes for home additions
The Village of Hawthorn Woods Building Department at 2 Lagoon Drive reviews residential permits on a standard 20-business-day plan-review timeline and publishes project-specific guidelines for interior remodels, basements, additions, decks, and more. Contractors and most subcontractors must register annually with the village (state-licensed plumbers are exempt from village registration), and inspections are booked by 3 p.m. the day before, with re-inspection fees drawn against a refundable bond. Homes on private well and septic can also trigger Lake County Health Department review when a project moves or adds plumbing. GS Construction manages the full permit process in Hawthorn Woods — contractor registration, application, drawings, and inspection scheduling — through final sign-off.
How your Hawthorn Woods 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.

Our project turned out better than we expected and as things were going along, we added more projects. Patryk, Greg and their team did a fantastic job. They were always so nice to work with, even suggesting things which was helpful. They never left a project until they thought it was perfect. We did a full kitchen remodel, even closing off a window to move a fridge and pantry to the other side to allow more cabinets and much needed counter space. They widen the entrance and the kitchen seems so much bigger. We think it’s Beautiful! They did laminated floors throughout the first floor, painted all walls and new baseboards. They created a wine bar which was just a cubby hole. They put in a pantry like cubby hole in our laundry room and added cabinets and above wall unit. One of the projects we had them add is new wooden stairs to the 2nd floor, white spindles and railing that curves instead of a wall and laminate floors on the 2nd floor. Other odd and ends that they never hesitated to do. We appreciate all they have done in our home, To us, it’s amazing how nice it is and how it should have been all the years we have lived here. Its exciting to show it off, it feels like a new house. These guys are amazing and would definately recommend them to anyone. Very reliable and easy to get in contact with when needed.
