SAN DIEGO (KGTV) — Several windows in the upper courthouse in downtown San Diego shattered spontaneously, necessitating awnings while the Judicial Council investigates the cause of the broken glass.

A spokesman said there had been three recorded incidents in recent months of random glass breaking in the building, which is less than five years old.

The first occurred on May 16, 2022, when an exterior window shattered on the 14th floor. The second happened on July 5, when an interior window shattered. The first two times the glass broke but did not fall. The third incident occurred on August 4, when a 12th floor window shattered spontaneously and fell onto an unoccupied interior roof on the 4th floor.

In the three recent incidents, no one was injured. As a precaution, however, the Judicial Council adds a canopy around the perimeter of the building.

This is not the first time there have been problems with the windows in this building. The 22-story building was constructed in 2018 and cost $556 million to build. Just nine months after completion, new windows were needed for parts of the building. These updates began in September 2018 and included the replacement of 13% of the bulletproof glass units in 22 judges’ rooms.

The first problems came from scratches on the interior surfaces – characterized as a “lightning defect”. The scratches on the bulletproof glass did not meet the quality standards specified for the project. These issues were resolved in fall 2018.

Now the council is in the process of retaining experts to assess the current window conditions.

The council is also in the process of retaining a contractor for the canopy work. The council will work with the building contractor to recover the cost of window repairs and all other related expenses.

It’s unclear how long building the canopy and investigating the cause of the broken glass will take.
