San Diego gym where platform collapsed had not obtained proper permits

The obstacle course gym in Barrio Logan where a platform collapse injured dozens of children was not issued a number of required permits, including permission to build the structure that fell, according to a report released Thursday.

City investigators determined that no building permits had been obtained for the warehouse that the gym — called Vault PK — operated out of since 2004, meaning none of the businesses inside had received proper permits.

Investigators found a long list of violations. The building didn’t have fire sprinklers, the right number of exits or the appropriate number of bathrooms. There were serious structural deficiencies as well, including a damaged support column that may not have been able to hold up the roof.

None of the businesses in the warehouse, which included Vault PK, a paintball arena, a CrossFit gym and a mixed martial arts facility, had been issued any permits to do any building of any kind.

Investigators found improperly constructed walls, mezzanines, stairs, partitions, restrooms, locker rooms and offices, all constructed without permits, according to the report.

The collapse happened Saturday night at Vault PK, a parkour gym where mostly children learn how to run, jump and navigate obstacle courses like those seen on “American Ninja Warrior.”
