California Civil Code Section 914(a)

This chapter establishes a nonadversarial procedure, including the remedies available under this chapter which, if the procedure does not resolve the dispute between the parties, may result in a subsequent action to enforce the other chapters of this title. A builder may attempt to commence nonadversarial contractual provisions other than the nonadversarial procedures and remedies set forth in this chapter, but may not, in addition to its own nonadversarial contractual provisions, require adherence to the nonadversarial procedures and remedies set forth in this chapter, regardless of whether the builder's own alternative nonadversarial contractual provisions are successful in resolving the dispute or ultimately deemed enforceable.
