Home Additions planned for how Lombard homeowners live.
In Lombard the calendar matters as much as the drawings. Plan review slows down exactly when most people want to build, so an addition is best planned a season ahead.
What Lombard asks for
The Village of Lombard requires a building permit for updates to existing structures, and its permit guide lists additions among the residential work that needs one. Drawings must be to scale, and the location of the work should be highlighted on the plat of survey. For projects over $10,000 in construction valuation, the village requires drawings signed and sealed by a licensed Illinois architect or structural engineer, which covers practically every addition.
Review time
Lombard reviews plans first come, first served. The village estimates about two to three weeks for new buildings or large additions, and says review during peak construction season, from late spring through the beginning of winter, can take four to six weeks. Once issued, a permit is valid for one year and may be extended depending on the circumstances.
Fees and responsibility
Permit fees are based on plan review fees, the total construction cost and the value of the electrical, plumbing and mechanical portions, and they are paid when the permit is ready for pickup. The village notes that the property owner is ultimately responsible for making sure the right permits are in place.
How ADS runs it
We measure the house and the lot during a free in-home visit, then write an estimate that separates foundation, framing, roofing, mechanical work and finishes. We pull the permit and schedule the inspections. ADS has finished kitchens, bathrooms, a staircase and a fireplace wall in Lombard, shown on that page. Confirm current requirements on the town page and with the municipality 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.

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.
