Fifteen @ Trump Tower

Chicago has 114 condominium listings in this directory, and the number that matters more is 111, since that's how many already have a working phone number attached. All 114 also list a website, so the gap here isn't missing data, it's just knowing where to look. Zip 60657 carries the largest cluster with 12 listings, followed by 60610 and 60611 with 10 each, so if you're searching by neighborhood, River North and Lincoln Park turn up more often than most other pockets of the city.

None of these listings carry a verified badge, and no paid placements are running in this category right now, which means what you're browsing wasn't arranged by anyone paying for position. Whenever that changes, a paid entry will carry the word Sponsored so it's obvious which one it is. If you manage one of these properties and the phone number or website link looks stale, you can claim the listing and update it yourself, which saves the next Chicago resident from dialing a number that goes nowhere. Call two or three before you commit to a tour, since details can shift faster than a directory updates.
