California has some of the strongest consumer protections in the country for home improvement work. Knowing them protects you, and a professional contractor will follow them without being asked.
The Contract Must Be in Writing
Home improvement contracts in California must be written and must include, among other things, the contractor’s name, address and license number, a description of the work and materials, the total price, the payment schedule, and the approximate start and completion dates. Verbal agreements for anything substantial are a warning sign.
Down Payment Limit
A contractor may not ask for a down payment of more than $1,000 or 10% of the contract price, whichever is less. A request for a large deposit “to order materials” before any work starts is one of the most common signs of a problem.
Progress Payments
After the down payment, payments should follow the work. California law does not allow a contractor to collect payment for work that has not yet been done or materials that have not been delivered. A good schedule ties each payment to a stage you can see — demolition finished, rough-in inspected, tile installed.
The Right to Cancel
Most home improvement contracts signed at home include a right to cancel within three business days, or five business days for homeowners aged 65 and older. The contract must include a notice explaining it.
Change Orders
Any change to the scope or price should be written and signed before the extra work is done. That protects both sides and prevents a final bill that does not match what you agreed.
Check the License
Look up any contractor on the Contractors State License Board website before signing. It shows whether the license is active, its classification, and whether the contractor carries workers’ compensation. IronNest Construction is CSLB #1130134, Class B (General Building).
Before You Sign
- Is the price fixed, and what does it exclude?
- Who pulls the permit?
- What is the payment schedule, stage by stage?
- What warranty applies to the workmanship?
- Who is your single point of contact?
We prepare contracts that follow these rules as standard, with a written fixed price and a schedule tied to the work. See how we work.
What Good Contracts Also Include
- A clear description of the materials, including brands or specifications where they matter
- Who is responsible for permits and inspections
- How hidden conditions will be documented and priced
- Cleanup and disposal
- The workmanship warranty
- How change orders are approved
None of this is complicated, and a professional contractor will have it in the standard paperwork. If a contract is a single page with a price and a signature line, ask for more detail before signing.
If Something Goes Wrong
Most disagreements are resolved by talking to the contractor with the contract in hand. Keep written records of changes and payments. If a dispute cannot be settled, the Contractors State License Board accepts complaints and offers dispute resolution for licensed contractors. Paying by check or card rather than cash also leaves a clear record.
If you are planning a project, IronNest Construction (CSLB #1130134) gives a written fixed price after a free site visit, handles the permit, and keeps one project manager on the job. Request a free estimate — we reply within 3–6 business hours.
Common Questions
Can a contractor ask for half the money up front?
No. For home improvement contracts, the down payment is limited to $1,000 or 10% of the contract price, whichever is less. After that, payments should follow work that has actually been done.
What if I want to cancel after signing?
Most home improvement contracts signed in your home can be cancelled within three business days, or five for homeowners 65 and older. The contract must explain how. After that period, cancellation depends on the contract terms.
Do small jobs need a written contract?
Any job beyond very minor work should be in writing. A written contract protects both sides and makes the scope, price and payment schedule clear.
