Here is how to choose a remodeling contractor in California: check the license on the Contractors State License Board (CSLB) website, including its classification, bond and workers’ compensation; get at least three written bids on the same scope; ask the questions below; and sign only a complete written contract with a down payment of no more than 10 percent of the price or $1,000, whichever is less. Each step takes minutes, and the same steps apply to a remodeler hired for one room and to anyone working out how to choose a general contractor for a whole-house project.

## Step 1: How to check a contractor license in California

In California, anyone who contracts for work on a project that requires a building permit, uses employees, or contracts for work valued at $1,000 or more in combined labor and materials must hold a current, valid CSLB license. Checking one takes two minutes:

1. Find the license number. The CSLB requires it on every advertisement, business card, bid and contract, so it should be easy to find. If it is missing, ask why.
2. Go to the CSLB’s “Check a License” page on cslb.ca.gov and enter the number (or search by business or personal name).
3. Read the status: it should say the license is current and active.
4. Read the classification. A remodel that combines plumbing, electrical and carpentry under one contract calls for a “B” General Building contractor, according to the CSLB. Single-trade jobs (only roofing, only plumbing) can go to a specialty license.
5. Check the bond and workers’ compensation sections. Licensed contractors must carry a contractor license bond, and a contractor with employees must carry workers’ compensation insurance.
6. Look at the address of record and any complaint disclosure.
7. When the contractor visits, ask to see the pocket license and a photo ID, and make sure the person matches the license. Salespeople must be registered with the CSLB as Home Improvement Salespersons.

**Example:** our own record. QA Builders is listed as Q A BUILDERS INC under CSLB License #1073096, Class B General Building, with a $25,000 contractor’s bond and workers’ compensation insurance on file with the state board, at the address of record 1917 Creek Drive, San Jose. That is what a clean record looks like.

Workers’ compensation matters more than most people think. The CSLB warns that if a worker is hurt on your property and the contractor has no coverage, you could be financially liable, and your homeowner’s insurance may not cover it. General liability insurance is not required by the state, but it covers damage to your property, so ask for a certificate of insurance.

## Step 2: Build a shortlist

When you search for [home remodeling contractors near you](https://qabuilders.com/full-home-remodeling/), you will find plenty of results. These are the best ways to narrow them down:

- **References.** Ask friends and relatives. If someone you trust had a good experience with a contractor, there is a good chance you will too.
- **Reviews.** Read online reviews on more than one site and look at how the company responds to problems, rather than only at the star average.
- **Relevant experience.** Pick a contractor who has done projects like yours. If you are remodeling a bathroom, look for a remodeler with [specific bathroom remodeling experience](https://qabuilders.com/bathroom-remodeling/); if you are adding space, one who builds additions.
- **A real business.** The CSLB suggests confirming a current business address and phone number. A contractor who is hard to find before the job will be harder to find if something needs fixing after it.

## Questions to ask a contractor before hiring

Choosing the contractor is one of the most important decisions in the project. These are the questions to ask a general contractor or remodeler at every meeting; compare the answers side by side.

| Question | What a good answer includes |
| --- | --- |
| How long has your company been operating? | A clear history; it tells you about stability and experience. |
| What experience do you have with this type of project? | Similar jobs you can see in photos or visit, ideally nearby. |
| What is your license number, and are you insured? | A number you can check today, plus certificates for workers’ compensation and liability insurance. |
| Who pulls the permits? | The contractor, in writing. If you are asked to pull them yourself as an owner-builder, you take on the legal obligations and risks of the job. |
| Can you provide references from previous clients? | Names and numbers of recent clients with similar projects. |
| What is your cost estimate, and what does it exclude? | A detailed, written estimate with allowances and exclusions spelled out. |
| What is the expected timeline? | A schedule with the main phases and what could delay them. |
| Who runs the job day to day? | A named project manager or supervisor and how to reach them. |
| How do you handle changes? | Written change orders with the price agreed before the work is done. |
| What warranty do you give, and in writing? | Clear written terms for workmanship, plus registration of manufacturer warranties. |

## Compare bids the right way

The CSLB recommends getting at least three written bids based on identical plans, specifications and scope of work, and warns against a bid far lower than the others: it usually means a mistake, missing work, or corners that will be cut later. Do not accept the lowest bid automatically.

Bids differ for real reasons too. The size of the area, the number of fixtures, whether walls move, the quality of materials, the age of the house and site work such as excavation all change the price. Structural changes, gutting a room and replacing plumbing or HVAC cost more than a cosmetic update. To understand the numbers before you compare them, read our cost guides for [kitchen remodels](https://qabuilders.com/kitchen-remodel-cost-san-jose/), [bathroom remodels](https://qabuilders.com/bathroom-remodel-cost-san-jose/) and [home additions](https://qabuilders.com/home-addition-cost-san-jose/) in San Jose.

Ways to lower the total without lowering the quality:

- **Bundle projects.** Doing the kitchen and a bathroom under one contract can cost less than two separate jobs, so ask whether the contractor will price them together.
- **Do the simple parts yourself.** Painting and similar small tasks can reduce the bill; leave plumbing, wiring and structure to licensed trades.
- **Look for energy incentives.** Utility and government programs sometimes support efficiency upgrades; check what applies before you choose equipment.
- **Buy carefully.** Lightly used furniture or appliances in good condition can save money, but ask your contractor before buying anything that must fit the design.

## Contracts and payments: what California requires

Yes, you should always sign a written contract with your contractor. It protects both of you and makes the details of the job clear, and California requires one for every home improvement project over $500 in combined labor and materials. The CSLB says a good contract covers:

- The work, described specifically, including brand and model where it matters (“install oak cabinets, maker and model as per plan”, rather than only “install cabinets”).
- The total price and when each payment is due.
- Who obtains the building permits.
- Start and completion dates.
- The contractor’s name, address and license number.
- Notices about your right to cancel, mechanics liens and allowable delays.
- Cleanup and debris removal, and any special instructions.

Three rules to know before you sign:

1. **The down payment is capped.** On a home improvement contract, the down payment should never exceed 10 percent of the contract price or $1,000, whichever is less. The exceptions are a contractor with a Blanket Performance and Payment Bond on file with the CSLB, and one who furnishes a performance and payment bond, a lien and completion bond, or a bond equivalent or joint control approved by the CSLB registrar for the job (Business and Professions Code section 7159.5(a)(8), explained below).
2. **You can cancel within three business days.** Under Business and Professions Code section 7159, you may cancel by a written notice emailed, mailed, faxed or delivered to the contractor’s place of business by midnight of the third business day after you received a signed and dated copy of the contract. For a senior citizen the period is five business days. The notice is not required when the contract was negotiated at the contractor’s place of business.
3. **Every change goes in writing.** Added work, substituted materials or a new completion date belong on a signed change order with the price, which then becomes part of the contract.

Never sign a blank or partly blank contract, and keep a copy of everything you sign.

### Should I pay a contractor 50% up front?

No. On a California home improvement contract, the down payment may not exceed $1,000 or 10 percent of the contract price, whichever is less, and each later payment may cover only work completed or materials delivered. On a typical kitchen, bathroom or addition, that makes $1,000 the most a contractor may ask before work starts.

Look for these headings in your contract, each with its statement in at least 12-point bold type:

| Heading in the contract | What must appear under it |
| --- | --- |
| Down Payment | The actual amount of the down payment, then: **“THE DOWN PAYMENT MAY NOT EXCEED $1,000 OR 10 PERCENT OF THE CONTRACT PRICE, WHICHEVER IS LESS.”** |
| Schedule of Progress Payments (when payments are spread over the job) | The amount of each payment and the work, materials or services completed for it, then: **“The schedule of progress payments must specifically describe each phase of work, including the type and amount of work or services scheduled to be supplied in each phase, along with the amount of each proposed progress payment. IT IS AGAINST THE LAW FOR A CONTRACTOR TO COLLECT PAYMENT FOR WORK NOT YET COMPLETED, OR FOR MATERIALS NOT YET DELIVERED. HOWEVER, A CONTRACTOR MAY REQUIRE A DOWN PAYMENT.”** |

Online advice that treats half down as normal does not fit a California home improvement contract, where half the price is far above the cap. Taking more than the cap, or payment ahead of the work, can bring CSLB discipline, and a violation of Business and Professions Code section 7159.5 is punishable as a misdemeanor ([CSLB progress payment bulletin](https://www.cslb.ca.gov/Resources/IndustryBulletins/2022/Industry_Bulletin_Progress_Payment_Restrictions.pdf)).

These limits do not apply to a contractor who has a Blanket Performance and Payment Bond on file with the CSLB (rare; the license check shows it), or who provides, for the whole job, a performance and payment bond, a lien and completion bond, or a bond equivalent or joint control approved by the CSLB registrar. Such a contractor may take payment before the work is done (Business and Professions Code section 7159.5(a)(8)).

A secure way to pay a contractor is to follow that schedule: pay for each phase once it is finished, and hold the final payment until the punch list is done, the city’s final inspection is signed off and you have the lien releases described in [closing the job out properly](https://qabuilders.com/how-to-choose-a-reliable-home-remodeling-contractor/#after-the-job).

## Red flags: how to spot a contractor scam

Unfortunately, some people in this industry set out to defraud homeowners. Be careful if a contractor:

- Has no license, or the wrong license for the work.
- Has no insurance, which can leave you liable for accidents or damage.
- Wants cash up front, or a down payment above 10 percent or $1,000 (whichever is less), before starting.
- Cannot or will not give credible references from previous clients.
- Is hard to reach and does not return calls or messages.
- Refuses to write or sign a contract.
- Comes in far below every other bid, or pressures you to sign on the spot.
- Suggests skipping permits to save money.

## After the job: closing it out properly

Before the final payment, walk through the work with the contractor and write a punch list of anything unfinished. Confirm that the city’s final inspection is signed off, and collect the warranty papers, manuals, paint colors and the approved plans. Ask for lien releases from the contractor, and from major suppliers and subcontractors, for the payments made.

If a problem appears after the work is complete, first contact the contractor directly by phone or in writing and explain it; many problems are resolved that way. If that does not work, you can contact the CSLB, your local consumer protection office or the state Attorney General’s office for help. A local builders’ association may also offer guidance.
