We are a sign company that is often hired by a large project management company. The project management company is hired by the business owner. And sometimes the business owner is actually renting a commercial space and does not own the property, so there is a property owner as well. It is usually the business owners full responsibility (either stated in the lease or stated in the letter of authority) to take care of any work that needs to be done to the building space including signs. We regularly file an NOC for our part of the work and that NOC will show the business owner and the property owner (as the fee simple title holder). Do we also need to file a Notice to Owner or preliminary notice in addition to the NOC?
