Hello, I am a general contractor in California and I am in the process of entering into a contract with a customer for a tenant improvement project. The tenant has full plans and city building permit issued which wouldn't be issued without the property owners signature of allowance in our city. What do I do as far as protecting myself if the tenant decides not to pay me? Is the property owner responsible for the payment through mechanics lean laws if the tenant decides not to pay the contract? Thanks, Andrew
