Is there mold in the building? If you have or suspect mold, you may need to notify the tenants immediately because some people may have allergies to molds.
What if you are forced to evacuate an area of the building? Do you have business interruption insurance? How do you quantify that? We would recommend hiring an expert in the type of tenancies you have, and try to put together a cash flow projection, showing your probable lost income during and after the repair period.
