If you’ve ever tried to build a garage yourself—or even just applied for a permit—you know it’s never “just a garage.”
Behind every structure that stands solid and legal is a maze of permits, zoning checks, and inspections that can stretch weeks or even months if you don’t know the process.
At Heartland Garage Builders, we’ve learned that building the garage is the easy part. It’s everything before and during construction that can stall a project. This article breaks down what really happens behind the scenes—and how our team keeps things moving when the paperwork piles up.
Before you can even apply for a building permit, your garage design has to pass zoning review. This step determines:
Zoning rules vary widely between municipalities—even between neighboring suburbs. A plan that works in Glenview might get rejected in Evanston.
Typical timeline: 1–3 weeks for review, depending on city workload.
Heartland Tip: We pre-screen every project’s address and setbacks before design begins. That way, you never pay for drawings that won’t pass zoning.
Once zoning clears, the building department steps in. Here’s what they’ll expect to see:
Many villages now require digital submittals through online portals. But others still demand physical copies, stamped and signed.
Typical timeline: 2–6 weeks, depending on whether revisions are required.
Common reasons for delay:
Heartland Tip: We maintain a database of permit requirements for every municipality we serve—so our plans are tailored to each village before they ever reach a desk.
Before construction starts, most towns require verification that you’re not building over or too close to:
This step sometimes means coordinating directly with ComEd, Nicor, or local public works—and that’s where many homeowners hit a wall.
Typical timeline: 1–2 weeks (longer if a line needs to be sleeved or relocated).
Heartland Tip: We handle all utility sleeve coordination up front. You’ll never be stuck on hold with the power company wondering why your permit is “on hold.”
Once your permit is issued, the municipality schedules inspections for every major phase of the build. Depending on your location, you can expect 5–7 inspections on a typical garage project:
| Inspection Type | When It Happens | What’s Checked |
| Pre-Pour / Foundation | After excavation, before concrete | Footing depth, forms, reinforcement, setbacks |
| Framing / Rough Carpentry | After framing & sheathing | Wall height, truss spacing, headers, fasteners |
| Electrical Rough-In | Before insulation/drywall | Wiring, circuits, GFCIs, grounding |
| Sheathing / House Wrap | Before siding | Moisture barrier, nail patterns, flashing |
| Roof / Insulation | Before finishing | Ventilation, insulation R-values |
| Final Electrical | Before closeout | Panel tie-in, fixtures, outlets, labeling |
| Final Building Inspection | At completion | Structural, electrical, egress, overall compliance |
Heartland Tip: We pre-schedule inspection windows to line up back-to-back, so you don’t wait three extra days between approvals.
Once the final inspection passes, you’ll receive your Certificate of Compliance or Final Approval Letter—proof that the structure is legal, safe, and fully permitted. Without it, you can’t insure or resell the property properly.
Heartland handles all closeout documentation, so your records are complete.
Typical timeline from permit to final:
It’s not the weather.
It’s not materials.
It’s paperwork.
The difference between a smooth project and a stalled one almost always comes down to how well the builder communicates with the city—and how early they plan for it.
