In California, can a Owner of a private project hold a progress payment to a GC because they have not received unconditional waivers (GC & Subs) from the previous months pay application? My Owner is continuously late on progress payments and they are claiming that they do not have unconditionals from the previous month. I (the GC) cannot supply the unconditionals in time because payment is always late. This is a self-perpetuating problem.
