Do I need a permit for a shed?

It depends on your location and shed size. Most jurisdictions require permits for sheds over 100-200 square feet. Use Permitech to instantly check the requirements for your specific address in Illinois, Wisconsin, or Indiana.

How long does it take to get a shed permit?

Permit approval times vary by jurisdiction, typically ranging from same-day to 2-4 weeks. Permitech helps you prepare a complete application to avoid delays and rejections.

AHJ stands for Authority Having Jurisdiction - the local government agency (city, county, or township) that reviews and approves building permits in your area.

What are setback requirements?

Setbacks are the minimum distances your structure must be from property lines, other buildings, or easements. These vary by jurisdiction and are critical for permit approval.

Common Rejection Triggers Across IL, WI, and IN

The repeat offenders

These issues show up across IL, WI, and IN because the rules are similar but the documentation standards vary.

Setbacks not shown or measured from the correct lot line
Missing or outdated plat of survey
Easements not called out on the site plan
Floodplain or stormwater triggers not addressed
Incomplete zoning calculation sheets

Why the same mistakes keep happening

Requirements live in different places: municipal PDFs, portal checklists, or staff emails. Without a structured workflow, important items get missed.

That is why Permitech focuses on verified requirements and evidence-backed checklists.

What to do next

Before you submit, confirm the AHJ, confirm setbacks, and verify the required documents. If you are unsure, Permitech surfaces these items early in the workflow.

Key takeaways

The same rejection triggers appear across Midwest jurisdictions.
Setbacks, plats, and easements are the biggest risk areas.
Verified checklists prevent last-minute surprises.
