In a recent interview with The San Diego Union-Tribune, San Diego Fire-Rescue Department spokesperson Jose Ysea revealed that no building permits had been filed prior to the construction of a platform that collapsed Saturday night, injuring dozens at a children’s birthday party.

On further inspection, it was found that the improperly-constructed platform was not the only safety issue to be found in the Main Street warehouse where the obstacle course gym Vault PK and other businesses have taken up residence.

San Diego city and fire inspectors found a list of violations during their search Sunday and Monday, including an improper number of exits, an inoperable sprinkler system and other structural deficiencies. According to Ysea, no building permits had been issued to any of the current businesses in the space.

A spokesperson for the Metropolitan Transit System, the building’s owner, says the company was not aware of improvements made inside the building by leaser Vault PK and other tenants. MTS has announced that the entertainment businesses will be ejected and leases terminated.

Said Mike Richmond, deputy chief of the City of San Diego’s code enforcement division, “If proper permits were obtained and if inspections were made by the city it would have avoided all the terrible things that happened to the affected people.”

San Diego police have confirmed that there will be no criminal investigation.
