Why Long Grove homeowners choose ADS

Home Additions planned for how Long Grove homeowners live.

Long Grove runs its building department through contractors, and the process is strict about order: nothing is reviewed until the deposit is paid and the documents are complete. An addition goes faster when the paperwork is assembled once, correctly.

How the village handles an addition

The Village of Long Grove says almost all building or property changes require a permit, and its examples include additions. Plan review and building inspections are contracted to SAFEbuilt, and every permit is submitted online through the Community Core portal. The village collects a security deposit for most projects, and deposits must be paid before plan review and permit processing can begin.

Exterior work and covenants

The village states that all exterior work requires engineering review and inspections, which applies to any addition. It also asks owners to check subdivision covenants with their homeowners association. Effective June 1, 2026, the village uses the 2021 International Building Code.

Contractors, inspections and hours

Long Grove does not require contractor registration, but contractors must enroll to use Community Core, and copies of contractor licenses are submitted with each project. Inspections run Monday through Friday in a morning window from 8:00 a.m. to noon or an afternoon window from noon to 3:00 p.m., with no same-day inspections. Posted construction hours are 7:00 a.m. to 7:00 p.m. on weekdays and 8:00 a.m. to 6:00 p.m. on Saturday.

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. 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.

Common questions from Long Grove homeowners

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.
