“Building permits create an inspection record that protects your investment. Unpermitted work is a disclosed defect that reduces the property's appraised value and can create lender issues at refinance or sale. Buyers' agents are now routinely pulling permit histories before making offers. Do everything permitted. The permit cost is 1.5–3% of project cost — it's the cheapest insurance you can buy.”
Get lien releases from every subcontractor and supplier before making each progress payment. California's mechanics lien law allows unpaid parties to lien your property even if you've paid the GC in full. Conditional lien releases at payment, and unconditional releases after payment clears, are the correct documentation sequence. Make this a contract requirement.
