Local Project Overview

Deck Construction · Kankakee County, Illinois

Permit required

In Illinois, a Deck Construction requires a building permit.

The county's Building Division, part of the Planning Department, processes building permit applications and contractor registration renewals through its online Building Division Portal, requiring a one-time personal account for applicants to submit permits, check application status, and upload required documentation. The City of Kankakee, the county seat, separately adopted the 2018 edition of the International Residential Code by ordinance, administered through its own Building and Code Enforcement Department rather than the county's. Plans are reviewed under the Kankakee County Planning Department, Building Division (unin code (IRC Kankakee County Buil); apply through Kankakee County Planning Commn before work begins.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).

Code Compliance & Inspections

Because of severe winter weather in Illinois, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Illinois Building Code.

Zoning & Cost Factors

Illinois zoning is highly localized. The Chicago metropolitan area has exceptionally complex and strict local ordinances compared to downstate rural counties. Fortunately, Illinois maintains relatively builder-friendly regulations, keeping base permit fees competitive.

What happens if I build a Deck Construction without a permit in Kankakee County?

Yes. Illinois generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Illinois Building Code.
