Home Additions planned for how Hinsdale homeowners live.
Hinsdale asks more of an addition than most villages do, and several requirements switch on at a specific size. Knowing the square footage early tells you which ones apply.
What the village asks for
The Village of Hinsdale’s single-family addition information sheet asks for plats of survey with the addition drawn to scale and stamped architectural plans that include floor area ratio overlays. A certified tree plan is required for an addition of 600 square feet or more, and an abutting neighbor contact form is required once the added area reaches 600 square feet. More than 2,500 square feet of disruption calls for a stormwater management permit, and the sheet also lists an approval letter from the Flagg Creek Sanitary District.
Historic properties
If the home is a local landmark or sits in the Robbins Park Historic District, the village asks owners to be aware of Certificate of Appropriateness review by the Historic Preservation Commission. That review covers exterior changes to a designated landmark and new construction or demolition in the district.
Inspections and hours
Rough framing, electrical, mechanical and plumbing inspections happen before walls are insulated. The sheet lists work hours of 8 a.m. to 8 p.m. on weekdays and 8 a.m. to 4 p.m. on Saturdays, with no work on Sundays. General contractors register with the village.
How ADS runs it
We measure the house and the lot during a free in-home visit and size the addition against the thresholds above before design goes further. The written estimate separates foundation, framing, roofing, mechanical work and finishes. We pull the permit and schedule the inspections. Confirm current requirements on the Hinsdale page and with the village before design begins.
How ADS builds an addition: zoning check, engineered drawings, permits, footings and roof tie-in, and the schedule you get in writing.

What else we build in Hinsdale, IL.
Five questions every homeowner asks first.
Plain answers - the kind we'd give a neighbor over coffee, not the ones written for a brochure.
Have a different question? Ask during your free estimate →-
How much does a typical kitchen or bathroom remodel cost?
Bathroom remodels in our area typically run $18,000–$45,000. Mid-range kitchens are usually $35,000–$80,000 - full custom kitchens can reach $120,000+. We give you a detailed estimate in writing after the in-home visit, so you see the numbers line by line before signing anything.
-
How long will my project take?
A bathroom is usually 3–5 weeks from demo to final walkthrough. A standard kitchen runs 6–8 weeks. Basement finishes are 5–8 weeks. We give you a written schedule before we start - and one project lead coordinates every trade, so the schedule doesn't stall between steps.
-
Do you handle the permits and inspections?
Yes - every time. We pull the permits, schedule the inspections, and meet with the inspectors. You don't deal with the village. We handle Buffalo Grove, Arlington Heights, Lombard, Glen Ellyn, Wheaton, and the rest of our service area.
-
Can we live in the house during the remodel?
Almost always, yes. We seal off the work zone with plastic, set up a temporary kitchen if we're remodeling yours, vacuum daily, and do a deep clean at the end. Most clients stay in the home for the full project - we plan the sequence around your daily life.
-
How do payments work?
A small deposit at signing, then progress payments tied to milestones (rough-in complete, drywall complete, final walkthrough). You never pre-pay for work that hasn't started. Final payment is only released after you sign off on the final walkthrough - not before.
