MTS is the owner of the warehouse and leases it out to small businesses. Friday, a spokesperson for MTS said it clearly had some responsibility in making sure the building permits were up to date.
In a previous statement, MTS reported "its lease with the tenant clearly requires [the tenant] to obtain all city permits and to comply with all of its regulations. Unfortunately, this did not happen."
The spokesperson went on to say MTS never signed a lease agreement with Vault PK parkour gym, where the accident happened. MTS says one of its tenants subleased space to Vault PK, unbeknownst to MTS.
The warehouse had not received any building permits since 2004. San Diego Fire-Rescue is responsible for conducting routine compliance inspections, although a city of San Diego spokesperson says Fire-Rescue wouldn't know to conduct inspections, considering a permit hadn't been issued in years.
