Two dozen Miami-Dade County apartment complexes, including two owned by the county, were placed on a list for unsafe structure violations on Monday following an emergency audit of the area, days after a condominium building crumbled to the ground last week.

The 24 structures failed to secure required recertifications after 40 years, according to the Miami Herald, which cited county records. The inquiry was initiated roughly 48 hours after Champlain Towers South, a 12-story structure that contained 136 units, partially collapsed on Thursday and was reduced to a 30-foot high pile of rubble. The building was in the process of receiving its 40-year recertification at the time of the incident.
