Hiring a general contractor in Los Angeles comes down to five checks. Confirm an active CSLB license. Confirm liability insurance and workers’ comp. Get at least two written, itemized bids. Put a payment schedule in the contract, tied to finished work. Confirm the permit plan through LADBS if the job touches structural, electrical, or plumbing work. Skip any one of these and you carry the risk if the job goes wrong.
Here’s the direct answer in full. In Los Angeles, hiring a general contractor means confirming their California State License Board (CSLB) license is active and matches the name on your contract. It means verifying general liability insurance and workers’ compensation. And it means comparing at least two or three written, itemized quotes before you sign anything. Any job with combined labor and materials over $500 legally requires a licensed contractor in California. Your contract should spell out the scope of work, materials, payment schedule, and start and completion dates. Structural, electrical, or plumbing work needs a permit pulled through the Los Angeles Department of Building and Safety (LADBS) before work starts, not after.
The rest of this guide walks through each step, what to ask, and the warning signs that mean it’s time to get a second bid.
Step 1: Confirm the License Is Real and Active
Start here. Every contractor doing work over $500 in Los Angeles needs an active CSLB license. Ask for the license number directly. Then check it yourself on the CSLB license lookup tool. The lookup shows whether the license is active. It shows the classification, such as B for general building or a C-specific class for trades like electrical or plumbing. It also shows any bond or disciplinary history tied to that number.
Match the name on the license to the name on your contract and invoices. A mismatch is a common problem. The license sits under one company name, but the contract is under another. That gap is one of the most common ways homeowners end up with no recourse when something goes wrong.
Step 2: Verify Insurance and Workers’ Compensation
A license alone doesn’t cover you if a worker is hurt on your property. It doesn’t cover you if a mistake damages your home either. Ask for a certificate of insurance showing general liability coverage. Confirm workers’ compensation for anyone on payroll or brought in as a sub. Then call the insurance carrier listed on the certificate to confirm it’s current. A certificate from six months ago tells you nothing about today.
Step 3: Get Written, Itemized Quotes
Get at least two or three quotes for anything beyond a small repair. A written quote should break out labor, materials, and any allowance for fixtures or finishes you haven’t picked yet. A one-line total with no breakdown makes it hard to compare bids. It also makes it harder to catch scope gaps later.
Watch for a quote that comes in far below the others. A number that low usually means one of three things: missing scope, lower-grade materials, or a contractor planning to make up the difference later with change orders.
Step 4: Read Reviews Past the Star Rating
A 4.8-star average with twenty reviews tells you less than a 4.5-star average with two hundred. Read the actual text, not just the number. Look for specifics: a named project, a neighborhood, a timeline, a dollar figure. A generic five-star review with no detail is worth less than one honest three-star review that explains what went wrong and how it got fixed.
Some companies operate as a referral network. They dispatch your project to an independent contractor rather than sending their own crew. If that’s the setup, ask directly who will be on-site and whose license covers the work. That’s a legitimate way to find a contractor. But you should know it going in, not discover it after signing.
Step 5: Confirm Permit Requirements Through LADBS
Los Angeles requires permits for most structural changes, electrical rewiring, plumbing relocation, and additions. A contractor who tells you a permit “isn’t necessary” for work that clearly needs one is a red flag, not a time-saver. Unpermitted work can complicate a home sale later. It may not be covered by insurance either if something fails.
Check permit requirements and pull records for a specific address through the LADBS permit search. Ask your contractor which permits the job needs. Ask who’s responsible for pulling them, too. Both belong in the contract, not in a verbal agreement.
Step 6: Put the Payment Schedule and Timeline in Writing
California caps the down payment on most home improvement contracts at 10% of the total price or $1,000, whichever is less. Beyond the deposit, tie every later payment to a specific, finished stage of work. Framing done. Drywall done. Final walkthrough passed. Never tie a payment to a calendar date alone.
Your contract should also set a realistic start date and an estimated completion date. It should say what happens if the project runs long. Ask your specific contractor for their own estimate instead of relying on averages. Older housing stock in neighborhoods like West LA and Silver Lake often adds time once walls open up and hidden issues surface.
What to Ask During the First Call
The first conversation tells you almost as much as the written quote that follows it. A contractor who answers these questions clearly and specifically is worth a second call. One who gets vague or defensive is a signal to move on.
- Who will actually be on the job site — your crew, or a subcontractor you bring in?
- How many active projects are you running right now, and where does mine fit in the schedule?
- Can you give me two references from a project similar in size and scope to mine?
- Who pulls the permit, and whose name is on it?
- What’s your process if we find a problem once the walls are open?
Write down the answers. If a second contractor gives you a very different answer to the same question, that’s worth asking about directly rather than assuming one of them is wrong.
How Long the Hiring Process Should Realistically Take
Rushing this process is where most bad hires start. A homeowner who calls one contractor, likes the sales pitch, and signs the same week skips almost every check on this list. Give yourself two to three weeks between your first call and signing a contract for anything beyond a small repair.
That window covers getting two or three quotes back, checking each license and insurance certificate, calling at least one reference per contractor, and reading the contract closely before you sign it. A contractor who pushes hard against that timeline, especially with a same-day discount, is optimizing for your urgency, not your outcome.
Los Angeles-Specific Factors That Affect Hiring
A few local conditions change what “hiring the right contractor” looks like in LA specifically. Older housing stock in neighborhoods like West LA, Silver Lake, and Echo Park often means knob-and-tube wiring, outdated plumbing, or foundation issues that only surface once a wall opens up. Ask any contractor bidding on an older property how they handle a discovery like that mid-project, and get the answer in writing, not just verbally.
Seismic retrofit requirements also matter more here than in most cities. If your project touches a home’s foundation, cripple walls, or soft-story construction, ask whether the contractor has handled LADBS seismic retrofit permits before, not just general remodeling permits. The two require different sign-offs, and a contractor unfamiliar with the retrofit process can add weeks to your timeline without warning you first.
Red Flags That Mean Get a Second Opinion
- Asks for full or majority payment up front, before any work starts
- Can’t produce a license number, or the number doesn’t match on the CSLB lookup
- Pressures you to sign the same day, or offers a discount only if you sign now
- Won’t put the scope, materials, or payment schedule in writing
- Tells you a permit “isn’t needed” for work that clearly requires one
- Has no verifiable insurance certificate, or won’t let you confirm it with the carrier

Frequently Asked Questions
Do I need a licensed contractor for a small home repair in Los Angeles?
Any job with combined labor and materials over $500 legally requires a licensed contractor in California. Below that threshold, licensing isn’t required. Checking references still matters, even for small jobs.
How do I know if a contractor’s license is still valid?
Check the license number directly on the CSLB’s online lookup tool. It shows current status, license classification, and any bond or disciplinary history tied to that number.
What’s a normal down payment for a remodeling project?
California limits down payments on most home improvement contracts to 10% of the total price or $1,000, whichever is less. Anything asking for more up front is worth questioning. [NEEDS SOURCE: verify current statutory cap before publish.]
Can I skip the permit to save time?
Skipping a required permit can create problems when you sell the home. It may also leave the work uninsured if something fails later. If LADBS requires a permit for the scope of work, get it before work starts.
How many quotes should I actually get?
Two is the minimum. Three is better, since it makes an unusually high or low bid easier to spot. Beyond three, the extra effort rarely changes the decision much.
