“Payment schedules in California are governed by the Home Improvement Contract law (Business & Professions Code 7159). Contractors cannot legally require more than 10% of the contract price or $1,000 (whichever is less) as a down payment on home improvement projects. Any contractor asking for 30–50% down before starting work is either uninformed about California law or using cash flow from your project to fund another.”
Specify a 'substantial completion' date and a daily liquidated damages rate in your construction contract. Liquidated damages ($500–1,500/day is typical for residential) create a financial incentive for the contractor to stay on schedule. Without this provision, schedule delays have no contractual consequence for the contractor.
