If the building owner believes that you are liable for the damages to the building and the consequential costs associated with that damage, they are free to sue you.
If you are sued, and you believe that a third party (like Zipcar) is liable for those damages, you can implede them as a third party defendant.
If you believe the insurance company should indemnify you for those damages, you can implede them as a third party defendant. This would require that there is a contract between you and the insurance company. There's a good chance that any contract is between the insurance company and Zipcar. If that's true, they would have no obligation to indemnify you.
There's also a possibility that any contract excludes consequential damages.
The cost of the security person is a consequential damage, not property damage.
