Legal Question in Real Estate Law in California

Rather than a statutory violation, this looks like a breach of contract. Mosh breach of contract law is based on centuries of court decisions. There may be some statutes that require a builder to adhere to the model's appearance and specifications too, but I would think this should be prepared as a breach of your contract with the builder......and obviously, you'll need to review the terms of the contract very carefully, to see what the builder was obligated to provide.
