Chicago building permits are automatically expired or voided if work hasn’t started in a given timeframe or if too much time has elapsed without any construction activity. In the adoption of updated and modernized construction codes, a new administrative provision now in effect changes the rules requiring when construction work has to start, how long construction can be inactive, and how to get extensions or reinstatements. Fees have also been updated.
The administrative provisions (chapter 14A in the updated building code) went into effect July 1, 2019.
Upshot: Under the new building code, owners have the same amount of time as before to start construction before a permit must be extended or reinstated, but there is less time allowed for construction inactivity after construction begins.
