Anxious Residents of Sister Tower to Fallen Florida Condo Wonder: Stay or Go?

The partly collapsed Champlain Towers South scared people who live in Champlain Towers North. But no one has ordered them to evacuate — yet.

SURFSIDE, Fla. — Philip Zyne peered over the balcony of his condo near Miami Beach around midday on Saturday and pointed to a large crack running in the parking lot below his unit. Normally, he might not have given it a moment’s thought. But Mr. Zyne, 71, lives at Champlain Towers North, the sister condo complex to the building in Surfside, Fla., that partially collapsed into a mass of rubble on Thursday, leaving four people dead and 159 missing. Now he was on high alert: Could the building where he lives be next? “I would’ve never noticed that if this hadn’t happened,” Mr. Zyne said.
