What are the required elements for a home improvement contract in California to be legally valid and protect me as a homeowner?
A valid California home improvement contract must be a detailed written agreement that includes specific legal notices and financial limitations to protect you. These requirements ensure clarity on the project scope, cost, and your right to cancel the agreement.
Here is what to check for to ensure your contract is valid:
Step 1: Verify the Contractor's License
Before signing, go to the Contractors State License Board (CSLB) website at cslb.ca.gov. Use the "Instant License Check" tool to confirm your contractor has an active license in the correct classification for your job and has workers' compensation insurance. The contract itself must display the contractor's license number.
Step 2: Confirm the Contract is a Complete Written Document
Do not sign a blank or incomplete contract. California law requires a written agreement that includes the contractor's full name, address, and license number, along with a detailed description of the work, materials, and equipment. It must also include the total project price.
Step 3: Review the Payment Schedule and Down Payment
The contract must have a clear payment schedule tied to the completion of specific project milestones. Critically, the down payment cannot legally exceed $1,000 or 10% of the total contract price, whichever is less. Never pay in cash.
Step 4: Locate the Notice of Cancellation
Your contract must include a conspicuous, three-day "Right to Cancel" notice. For work related to a declared disaster, this period is extended to five business days. This notice gives you the right to cancel the contract without penalty within that timeframe. Make sure you understand the cancellation process described.
Important considerations: The contract must state the approximate start and end dates for the project. Any changes to the original plan, known as "change orders," must be in writing and signed by both you and the contractor before that new work begins. Do not rely on verbal agreements.
Note: A contract that fails to meet these requirements may be unenforceable by the contractor. Be wary of any contractor who pressures you to sign quickly or requests a large upfront payment.
