Home Additions planned for how Buffalo Grove homeowners live.
A room addition in Buffalo Grove is a village project before it is a construction project. The lot, the plat of survey and the permit decide what can be built, so we start there and design second.
How Buffalo Grove permits an addition
The Village of Buffalo Grove handles building permits online through its BS&A permit portal, and says standard permits take approximately 10 business days for review and issuance. Village staff verify a contractor’s registration status when the application is filed. The village fee schedule prices a conditioned residential addition at 1.75% of valuation with a $200 minimum, and an unconditioned addition at a flat $500. Permits for additions and new construction expire 365 days after they are issued, so the schedule has to be realistic before the permit is pulled.
What to settle before drawings
- Which rooms the addition connects to, and whether a wall between them is load-bearing. The village asks plans to state that and how it was determined.
- Where materials and a dumpster will sit. Buffalo Grove does not allow them on the street or in the parkway.
- Work hours. The village permits construction from 7 a.m. to 7 p.m. on weekdays and 8 a.m. to 7 p.m. on weekends.
- Whether a homeowners association has to approve the exterior.
How ADS runs it
We measure the house and the yard during a free in-home visit, then write an estimate that lists foundation, framing, roofing, mechanical work and finishes as separate lines. One project lead coordinates every trade, we pull the permit and we schedule the inspections. Review the Village of Buffalo Grove permits and inspections page and confirm current requirements for your lot 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.

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.
