“The lien waiver is the document that protects homeowners from contractor payment disputes cascading down to subcontractors. California's mechanics lien law allows subcontractors and suppliers to place liens on your property if the general contractor doesn't pay them — even if you paid the GC in full. Get conditional lien waivers from all subs and suppliers at each progress payment. Make it a contract requirement.”
A pre-construction preconstruction meeting with all major subcontractors is worth scheduling before any work begins. This meeting aligns everyone on project logistics (site access, material storage, work hours, LADBS inspection procedures), identifies interface coordination issues between trades, and establishes the project communication protocol. It's 3 hours that saves 30 hours of conflict resolution during construction.
