Red Flags When Hiring a Contractor: What to Watch For in 2026

How Do You Know If a Contractor Is Legitimate Before the First Meeting?

Go to cslb.ca.gov right now and look up their license number. Takes 30 seconds. If they cannot give you a license number before you meet, the meeting is already a waste of your time.

In my experience building homes across Silicon Valley since 2017, the contractors who hesitate to share their CSLB number are almost always hiding something - an expired license, a suspended bond, a workers' comp lapse, or a disciplinary action on their record. Legitimate contractors are proud of their license number. They put it on their trucks, their business cards, their email signatures.

Here is what to verify on the CSLB lookup before you shake anyone's hand:

• License status: Must say "Active." Anything else - expired, suspended, canceled - means they cannot legally contract in California.
• Bond status: Active. The contractor's bond is a $25,000 surety that protects you if they walk off the job or refuse to fix defective work.
• Workers' compensation: Active, unless they are a sole owner with no employees. An uninsured crew working on your property means you could be liable if someone gets hurt.
• Disciplinary actions: Any citations, revocations, or judgments show up here. According to CSLB complaint data, about 1 in 6 complaints results in formal disciplinary action - and those records stay public forever.

If you want this monitoring done automatically, tools like Opsite pull live CSLB data on contractors you are considering and alert you if anything changes during your project - license lapses, bond cancellations, new disciplinary actions. That kind of ongoing visibility used to be something only other contractors had.

What Does a Suspiciously Low Bid Actually Mean?

It means the contractor plans to make their margin somewhere else. That somewhere else is called change orders.

From working with homeowners on projects ranging from $50K to $2M+, I have seen this pattern play out dozens of times. A contractor bids $80,000 on a kitchen remodel when every other bid comes in at $120,000-$135,000. The homeowner thinks they found a deal. Six months later, they are $160,000 in and the kitchen still is not done.

Get three bids. Not two, not one. Three. And if the lowest bid is 30% or more below the other two, that is not a deal. That is a contractor who will hit you with change orders, use cheaper materials than specified, cut corners on rough work you will never see, or simply run out of money and disappear.

Based on 2026 construction cost data, a mid-range kitchen remodel in the Bay Area runs $85,000 to $150,000. A bathroom renovation runs $25,000 to $65,000. A whole-house remodel runs $300,000 to $700,000+. Those ranges exist because of real labor and material costs. A bid that lands 40% below the floor of those ranges is mathematically impossible to execute at the promised quality.

As a contractor, I can tell you that a low bid is not a gift. It is a plan. The plan is to get the job, then make the money back through change orders, material substitutions, or simply by billing for time and materials on items that were supposed to be fixed-price. By the time you figure it out, they have your deposit and three months of progress payments.

Here is a quick comparison of bid types and what they signal:

What Red Flags Should I Look For in a Construction Contract?

A vague contract is not a contractor being casual. It is a contractor leaving themselves room to charge you more later. Every blank, every "TBD," every undefined allowance is a future change order in disguise.

Based on typical project data from Bay Area contractors, the most common contract problems I see are:

No scope of work. The contract says "remodel kitchen" with no description of what that includes. Does it include demo? Moving the plumbing? New electrical panel? Painting? Every one of those becomes a billable extra if it is not in writing.

Missing draw schedule. A draw schedule defines exactly how much you pay and when, tied to specific milestones - framing complete, rough inspections passed, cabinets installed, final punch list signed off. If your contract has no draw schedule and just says "pay as we go," you have no leverage when work stalls. The draw schedule is one of the most important documents in any construction project. Read what a draw schedule is and how it protects you before you sign anything.

No change order process. The contract should state that all change orders must be in writing, signed by both parties, with a price agreed before work begins. If the contract is silent on this, you are giving your contractor a blank check.

No lien waiver provision. Your contractor hires subcontractors and material suppliers. If they do not pay those subs, those subs can file a mechanic's lien against your property - even though you paid the GC in full. Require conditional lien waivers at each draw payment and an unconditional lien waiver at final payment. This is non-negotiable.

No warranty clause. California law requires a minimum one-year warranty on contractor workmanship, but many contracts are silent on specifics. Push for two years on labor and the full manufacturer warranty on materials in writing.

As a contractor, I can tell you that most homeowners who get burned do so because they signed a contract without reading it. Not because they did not want to read it, but because they did not know what to look for. A full AI-powered contract review from a platform like Opsite will flag every vague clause, missing provision, and high-risk term before you sign - for a fraction of what one bad change order will cost you.

How Do You Spot a Contractor Who Will Abandon the Job Mid-Project?

The warning signs are almost always there before they disappear. You just have to know where to look.

As a licensed GC who has completed hundreds of remodels, I have seen the pattern enough times to recognize it early. The contractor who abandons jobs is usually the same contractor who:

• Takes an oversized deposit upfront (more than 10-15% of the contract value)
• Starts strong for two to three weeks, then the crew shows up less and less frequently
• Has a new excuse every week for why materials are delayed or inspections are backed up
• Gets increasingly hard to reach - response time goes from same-day to 48 hours to a week
• Asks for the next draw payment before the milestone is actually complete
• Has no history of completed permits in the county where you live

That last point is something most homeowners do not know they can check. Your local building department keeps public records of every permit ever pulled on a property address, and who pulled it. A contractor who claims to have done 50 kitchens in Palo Alto but has zero active or completed permits on file in Santa Clara County is lying to you.

If your contractor takes 48 or more hours to return a text during the job, that is a red flag. During active construction, anything longer than same-day is unacceptable. Communication breakdown is almost always the first symptom of a project going sideways.

According to CSLB complaint data, job abandonment is one of the top three causes of formal contractor discipline in California. The homeowners who avoid it are the ones who check permit history, verify references on recently completed projects (not projects from five years ago), and put communication expectations in writing as part of the contract.

What Are the Change Order Red Flags to Watch For in 2026?

Change orders are legitimate. Hidden conditions, design changes, and scope expansions happen on almost every remodel. The problem is not change orders - it is padded change orders that the homeowner has no way to evaluate.

From working with homeowners on projects ranging from $50K to $2M+, I see change order padding of 15-30% above actual market rates on projects where the homeowner has no reference point. That is not rare. That is the default when a contractor knows you cannot check their pricing.

Here is what padded change orders look like in practice. Your contractor presents a change order for $12,000 to reroute a drain line they "discovered" was in an unexpected location. Is $12,000 reasonable? Without knowing that a licensed plumber in the Bay Area charges $150-$200 per hour and this job takes 8-12 hours plus materials, you have no idea. The contractor knows that. And they price accordingly.

The red flags in a change order:

• No breakdown of labor hours, labor rate, and material cost - just a lump sum
• Urgency pressure: "I need an answer today or we have to stop work"
• Change order presented verbally, not in writing
• The new scope overlaps with work already covered in the original contract
• Price is presented as final with no room for questions

Never approve a change order on the spot. You are entitled to 24-48 hours minimum to review any change order, regardless of what the contractor says. And every change order must be in writing before any work begins - that is California law under Business and Professions Code Section 7159.

Opsite's Change Order Analyzer lets you upload a change order PDF and get an AI-powered review that cross-references the pricing against current California market rates, flags items that overlap with your original contract scope, and generates a ready-to-send negotiation email if the pricing is padded. That kind of instant market check used to require hiring a second contractor to quote the same work.

How Do You Protect Yourself Once the Job Has Already Started?

Most homeowner protection guides focus entirely on the hiring phase. But the real financial exposure happens after you have already signed and the crew is in your house.

Here is what you should be doing throughout the project, not just at the start:

Require lien waivers at every draw payment. Every time you make a progress payment, get a conditional lien waiver from the general contractor and any major subcontractors. At final payment, get unconditional waivers from everyone. This protects your property from mechanic's liens even if your GC does not pay their subs.

Never pay ahead of completed milestones. Your draw schedule exists for a reason. Plumbing rough-in payment releases when the plumbing rough-in is done and inspected - not when the contractor says it will be done next week. If they need money to buy materials for the next phase before the current phase is finished, that is a cash flow problem on their end, not your responsibility.

Keep a contingency of 15-20%. Not 10%. Based on 2026 construction cost data, projects that hit zero surprises are the exception, not the rule. Hidden water damage, outdated electrical panels, unexpected soil conditions - every remodel finds something. If you have budgeted exactly what the contract says and nothing more, the first surprise puts you in a negotiating position from a place of desperation.

Document everything. Photos of every phase before walls close. Written records of every conversation about scope. Text messages count. Do not rely on verbal agreements for anything that involves money or timeline.

Watch the permit status. Every permit your contractor pulls has a status that updates when inspections are called and passed. If your framing permit has been open for three months with no inspection called, either the work is not done or the contractor is avoiding the inspection - neither is good. Opsite's Property Watch monitors permit activity at your address and alerts you to changes automatically, so you have real-time visibility without having to log into the building department portal every week.

The homeowners who come out of a remodel intact are not the ones who got lucky. They are the ones who treated the project like a business transaction from day one - verified credentials, read the contract, documented milestones, and stayed informed throughout. That is not paranoia. That is how construction works.

Frequently Asked Questions

How do I check if a contractor is licensed in California?

Go to cslb.ca.gov and search by license number or business name. The search is free and takes under a minute. You will see the license status (active or not), bond status, workers' compensation status, classifications, and any disciplinary actions on record. If a contractor will not give you their license number before your first meeting, that alone is a red flag.

What is the legal deposit limit for a contractor in California?

Under California Business and Professions Code Section 7159, a contractor cannot legally collect more than $1,000 or 10% of the total contract price - whichever is less - as a down payment before work begins. Any contractor asking for 20%, 30%, or 50% upfront is either unaware of the law or deliberately ignoring it. Both scenarios are problems.

How many bids should I get before hiring a contractor?

Three bids minimum. Not two, not one. Three. With three bids, you start to see the market rate for your project and can immediately spot outliers on both ends. If you only get two bids and one is lower, you have no idea whether the lower one is reasonable or dangerously underpriced. The third bid is what tells you.

Is it a red flag if a contractor wants to be paid in cash?

Yes. Cash payments make it harder to document what you paid, when you paid it, and for what phase of work. Legitimate contractors accept checks or bank transfers and provide receipts. A contractor who insists on cash is often trying to avoid a paper trail - which protects them, not you. Always pay by check or bank transfer and keep records of every payment with the corresponding draw milestone it covers.

What should I do if my contractor goes silent mid-project?

Send a written notice - text or email - with a 48-hour response deadline. Document the date and content of every communication attempt. If they do not respond, send a formal written demand letter via certified mail. If work has stopped entirely, contact the CSLB to file a complaint and consult with a construction attorney before making any more payments. Never make additional payments to a contractor who has gone dark.

What does CSLB stand for and how can it help me?

CSLB stands for California Contractors State License Board. It is the state agency that licenses and regulates contractors in California. Beyond the free license lookup tool, the CSLB operates a Contractors State License Board Arbitration program for disputes under $12,500, and their enforcement division investigates complaints against licensed contractors. Filing a CSLB complaint creates a public record on the contractor's license and can trigger an investigation.

How do I know if a change order price is fair?

Ask for a full breakdown: hours of labor, hourly rate, and an itemized list of materials with unit prices. Then get a second opinion - either from another contractor or by using a change order analysis tool. In the Bay Area, licensed subcontractor labor runs $95-$200 per hour depending on trade. If the math on labor plus materials does not add up to the change order total, you are looking at padding. Never approve a change order verbally or under pressure - you are always entitled to time to review.

Is it a red flag if a contractor says I do not need a permit?

Almost always, yes. In California, permits are required for any work that involves structural changes, electrical, plumbing, mechanical systems, additions, or room conversions. A contractor who says you do not need a permit is either uninformed or is trying to avoid the inspections that would catch substandard work. Unpermitted work can also create serious problems when you sell the property, including required disclosure and remediation at your expense.
