Building Permits & Construction
Lake Bluff Steep Slope Construction Study and Permit Abeyance Period: July 6, 2023 - April 6, 2024
During the Permit Abeyance Period, the Village will not accept applications for, and will not issue, any permits for any construction within the steep slope zone along Lake Michigan that requires a building permit from the Village. However, the following construction activity within the steep slope zone requiring a building permit is exempted from this prohibition and permit applications for such construction will be accepted: repairs or general maintenance of the bluff or structures or utility facilities on the bluff, construction activity entirely within an existing building, or restoration of property, facilities, and structures that suffer a casualty loss. For a property containing a steep slope zone, the Village will continue to accept applications for construction activity located outside of the steep slope zone. Read more.
