A licensed GC's honest guide to vetting, comparing, and hiring the right contractor - without getting burned.

How Do I Know If a Contractor Is Legitimate Before I Call Them?

Check their CSLB license before you do anything else. Go to cslb.ca.gov, type in their license number, and look at four things: active status, correct classification (Class B for general contractors), active bond, and active workers compensation insurance. This takes 30 seconds and it will save you from a world of hurt.

According to CSLB complaint data, more than 40% of consumer complaints involve unlicensed contractors or contractors operating outside their licensed classification. Unlicensed means no bond, no workers comp, and almost no recourse when things go wrong.

Here is what a clean CSLB record looks like versus a problem one:

What to CheckGood SignRed Flag
License StatusActiveExpired, Suspended, or Revoked
ClassificationB - General BuildingWrong class or none listed
Contractor BondActiveInactive or missing
Workers CompActive or Exempt (sole prop, no employees)No coverage listed
Disciplinary ActionsNone on recordCitations, fines, prior complaints

If anything shows Expired or Suspended - stop there. A polished sales pitch does not fix a suspended license.

How Many Bids Should I Get for My Remodel in 2026?

Three bids. Not two, not one. Three. Here is why the number matters: with two bids you only know who is cheaper. With three bids you see what the market rate actually is.

Based on typical project data from Bay Area contractors, a mid-range kitchen remodel in the Bay Area runs $65,000 to $125,000 in 2026. If you get two bids at $95,000 and $68,000, you cannot tell which one is right. A third bid at $88,000 tells you immediately that the $68,000 contractor is suspiciously low.

As a licensed GC who has completed hundreds of remodels, I can tell you the cheapest bid is almost never the best bid. A contractor who comes in 30% or more below the others is either missing scope, planning to hit you with change orders later, or will run out of money mid-project and walk off the job.

Always request itemized bids - not lump sums. "Kitchen remodel: $68,000" tells you nothing useful. You want separate line items for:

  • Demolition and debris hauling
  • Framing and structural work
  • Plumbing rough-in and fixture installation
  • Electrical rough-in and any panel upgrades
  • HVAC modifications
  • Drywall, tape, and texture
  • Cabinets and countertops (with allowances clearly stated)
  • Tile and flooring
  • Finish carpentry and hardware
  • Permits and inspections

Itemized bids are the only way to do an accurate side-by-side comparison. The free estimate comparison tool at homeowners.useopsite.com/compare lets you upload bids and compare them line by line to see exactly where the numbers diverge.

What Red Flags Should I Watch for Before Signing Anything?

Seven red flags appear in nearly every contractor fraud case or failed project I have seen. If your contractor hits two or more of these, do not sign anything.

1. No physical address. A P.O. box or just a cell phone number is a problem. Legitimate general contractors have a verifiable office, shop, or business address.

2. Demands more than 10% deposit. California law caps deposits at 10% of the contract price or $1,000 - whichever is less. Any contractor asking for $5,000 upfront on a $50,000 job is breaking the law.

3. Pressures you to sign immediately. "This price is only good today" is a manipulation tactic. A legitimate contractor is not going to evaporate overnight.

4. No written contract. Every California contractor is legally required to provide a written contract for jobs over $500. Verbal agreements mean nothing in a dispute.

5. Cash only. Legitimate contractors accept checks or bank transfers. Cash-only requests are about avoiding paper trails when things go wrong.

6. Cannot provide proof of insurance. Ask for a certificate of general liability insurance. If they hesitate or say "I will get that to you later," walk away now.

7. Suggests skipping the permit. "We can do this without a permit to save you money" is not a savings. Unpermitted work can void your homeowner's insurance, prevent you from selling your home, and require costly tear-out and redo later.

As a contractor, I can tell you that asking to see a certificate of insurance is not offensive. Any GC who gets defensive about that request is hiding something.

How Much Deposit Can a Contractor Legally Charge in California in 2026?

California law caps the deposit at 10% of the total contract price or $1,000 - whichever is less. This is not a guideline. It is the law, enforced by the CSLB.

That means on a $150,000 room addition, the maximum legal deposit is $1,000. Not $15,000. One thousand dollars. The cap does not scale up with project size.

Based on 2026 construction cost data and CSLB enforcement records, deposit abuse is one of the top three patterns in contractor fraud complaints in California. A contractor who insists on $10,000 upfront before they have pulled a permit or framed a single wall is either breaking the law or testing how easily they can take advantage of you.

After the initial deposit, payments should follow a draw schedule tied to completed work milestones - not to your contractor's cash flow needs. A safe payment structure for a $100,000 project looks like this:

  • $1,000 at contract signing (legal maximum deposit)
  • $25,000 after demo and rough framing complete and inspected
  • $25,000 after rough mechanical (plumbing, electrical, HVAC) passes inspection
  • $25,000 after drywall and paint complete
  • $24,000 at substantial completion with all final inspections signed off

Never pay ahead of completed work. The free deposit calculator at homeowners.useopsite.com/deposit shows exactly what the legal maximum deposit is for your project size.

What Questions Should I Ask a General Contractor Before Hiring Them?

Here are the ten questions that separate real contractors from bad ones. A good contractor answers these directly. Vague or defensive answers are information - act on them.

1. Can I have your CSLB license number? Every licensed contractor gives this without hesitation. Then verify it yourself.

2. Who pulls the permits - you or your subs? Your GC should always pull the permits. If a sub is handling it, that is a coordination problem waiting to happen.

3. Will all subcontractors be licensed? Yes is the only acceptable answer. Ask for their license numbers if you want to verify.

4. How do you handle change orders? In writing, signed by both parties, before work proceeds. "We will sort it out later" is not an answer.

5. What does your draw schedule look like? Milestone-based, not calendar-based. You pay for completed work, not for time passing.

6. What does your warranty cover and for how long? California requires a minimum one-year warranty on all construction work. Good contractors offer two to three years on their labor.

7. Who is the on-site supervisor every day? Is it you, a project manager, or a lead carpenter? Know who you are calling when a problem comes up.

8. How many active projects are you running right now? A GC with eight projects and a two-person crew is overextended. Know what you are getting into.

9. Can you provide three recent references from similar projects? Not just names. Actually call them and ask about communication, budget adherence, and how problems were handled.

10. How do you handle unforeseen conditions? You want: written notice to you, written quote, your written approval before any additional work proceeds. Any other answer is a problem.

In my experience building homes across Silicon Valley since 2017, the contractors who answer these questions confidently and without hesitation are the ones worth hiring. Get the full 50-question checklist at homeowners.useopsite.com/questions-to-ask-contractor.

What Does Working with a Good General Contractor Actually Look Like?

A good GC communicates proactively. You should not be the one always chasing updates.

Weekly written updates. Your GC contacts you at least once a week with a summary of what was completed, what is scheduled next, and any issues identified. If you are always initiating contact and waiting 48 hours or more for a reply, something is wrong.

Permits posted before work begins. The building permit card should be visible at the job site before demolition starts. Framing, rough mechanical, insulation, and final inspections happen throughout the project. Your GC schedules all of them. Do not let any get skipped.

Lien waivers at every draw payment. At each payment milestone, request a conditional lien waiver from your GC and from each major subcontractor. This protects you from mechanic's liens - situations where a subcontractor who was not paid by your GC places a lien on your property even though you already paid in full. From working with homeowners on projects ranging from $50K to $2M+, I have seen lien issues derail more than a few home sales at the worst possible moment.

A punch list before final payment. Walk the job before releasing your final payment. Document every incomplete or deficient item in writing. The final payment is your leverage - do not release it until the punch list is fully closed out.

Platforms like Opsite give contractors and homeowners a shared view of project status, draw schedules, and documentation in one place. If your contractor uses project management software, that is a good sign. If you are a contractor looking to build better homeowner trust through transparency, Opsite's features are worth a look.

Frequently Asked Questions

What is the difference between a general contractor and a specialty contractor?

A general contractor holds a Class B license in California and manages the full project - coordinating subcontractors, pulling permits, and owning the overall schedule and budget. Specialty contractors hold C-class licenses for specific trades: C-10 for electrical, C-36 for plumbing, C-20 for HVAC. For any remodel involving multiple trades, you hire a GC who then coordinates the licensed specialty subs.

Do I need a building permit for a kitchen remodel in California?

Yes, in almost all cases. Work involving structural changes, electrical upgrades, new plumbing runs, or HVAC modifications requires a building permit in California. Cosmetic updates like painting or cabinet refacing typically do not. Never let a contractor talk you into skipping permits - unpermitted work can complicate a home sale and create serious liability if something fails later.

How do I verify a contractor's license in California?

Go to cslb.ca.gov and use the license check tool. You can search by license number, business name, or contractor name. The free checker at homeowners.useopsite.com/check pulls live CSLB data with a cleaner interface and takes about 10 seconds.

What is the difference between a fixed-price and cost-plus contract?

A fixed-price contract locks in the total project cost upfront - your maximum exposure is capped. A cost-plus contract means you pay the actual cost of materials and labor plus a markup percentage (typically 15 to 25%). For most homeowners, fixed-price is safer because you know exactly what you are committing to. Cost-plus can work for loosely defined scopes but requires high trust and extremely detailed record-keeping.

What is a lien waiver and why do I need one?

A lien waiver is a document from your contractor or a subcontractor confirming they have been paid for completed work and waiving their right to file a mechanic's lien against your property. Without lien waivers, a subcontractor who was not paid by your GC can legally place a lien on your home - even if you already paid your GC in full. Always collect lien waivers at every draw payment.

How long does a typical kitchen remodel take in 2026?

A mid-range kitchen remodel runs 8 to 14 weeks from demolition to final walkthrough, based on current Bay Area project timelines. Add 3 to 8 weeks before that for the permit approval process. Custom cabinetry is typically the longest lead-time item - 4 to 8 weeks from order to delivery. Plan your project start date around that lead time.

What should I do if my contractor abandons the project?

Document everything immediately: photos of the current work state, all text and email communications, copies of every payment made. Do not release any remaining funds. File a complaint with the CSLB at cslb.ca.gov. If the contractor is bonded, file a claim against their contractor's bond. For disputes over $10,000, consult a construction attorney before taking additional steps.

How much contingency should I budget for a home remodel?

Add 15 to 20% on top of your contractor's bid as a contingency buffer. Not 10% - 15 to 20%. Older homes (pre-1980) should be at the higher end because outdated wiring, old galvanized pipes, and other surprises are common once walls open up. Every project hits something unexpected. The contingency is not pessimism - it is what keeps your project moving when reality diverges from the bid.
