Only takes 5 minutes to read! In part two, we will continue the discussion on AIA agreements. If you’re an owner, a contractor or subcontractor, contact me here with questions or comments about AIA agreements. Get landlord signoffs wherever appropriate. The owner of the property, the landlord, has to sign off on practically every little bit of work before it is started. If not, the work will likely be considered a breach of your lease agreement. In this case, you could end up spending a quarter of a million dollars having work done on your property only to have the landlord then claim you breached the lease in doing so, and may even be able to have you evicted.
