  "articleBody": "California consumer construction law and guidance from the Contractors State License Board (CSLB) outline standard, safer contract terms for residential projects such as room additions. CSLB explains that a **written home improvement contract** is required when the job exceeds a low dollar threshold and must include a description of the work, materials, approximate start and completion dates, and a schedule of payments tied to defined stages of work. CSLB consumer publications highlight a key protection: the **down payment is legally limited** to the lesser of 10% of the contract price or $1,000 for most home improvement contracts. Any contractor asking for more may be violating state law. Best practices from CSLB and the Federal Trade Commission recommend using **progress payments** based on completed milestones (e.g., foundation, framing, rough-in, finishes) rather than time-based or front-loaded payments, and withholding a reasonable final payment until after final inspection and completion of punch-list items. Standard contract clauses described in consumer and industry resources include requirements for change orders to be **in writing**, signed by both parties, and to specify additional cost and time. California’s home improvement contract regulations also require specific notices, such as the **three-day right to cancel** for certain contracts signed at the home and the “Mechanics Lien Warning,” which informs owners about subcontractor and supplier lien rights. Risk management guidance from insurers and construction law commentators suggests clarifying who pulls permits, how unforeseen conditions are handled, and what warranty terms apply. While warranty duration may vary, many contractors reference one-year workmanship warranties, though manufacturers’ warranties on materials can be longer. Homeowners are encouraged by CSLB and consumer advocates to avoid paying in cash, to obtain receipts, and to never let payments get ahead of completed work.",
