What requires a building permit in Oak Park?

Fence permits are needed except for repair or replacement of existing fencing not exceeding 100 square feet; on interior lots, fences within 35 feet of the front lot line must be open and no more than five feet high. Sprinklers, fire alarms, water service and dumpsters on the street each need a separate permit.

Demolishing a structure (garage or house) or structural elements requires a Cook County Demolition Permit to accompany the village application.

Illinois leaves building codes to local government, but since 1 January 2025 any local code must regulate structural design at least as strictly as baseline editions of the International Building, Existing Building and Residential Codes, and where no code was adopted the statute sets minimums for commercial buildings and new homes (Public Act 103-0510).
