I don't know what the 'normal' timeline is for permit issuance for construction projects in Chicago, but this links says City Hyde Park received its foundation permit in March and six months later its construction permit in September. So if Vue53 received a foundation permit on May 21, would it normally be six months before the construction permit is issued? That would put that construction permit issuance in late November. (I'm assuming it hasn't been issued already.)
