A mistake that could cost you too much money

Have you ever wondered why some construction projects go smoothly, while others turn into endless rework and litigation? The reason is simple: the contractor. More specifically, his competence and license.

For reference: In some states, such as California, obtaining a general contractor license in California — a prerequisite for work on construction projects that cost more than $500. However, many customers don't check to see if contractors are licensed, risking serious problems.

Let's say you find a great offer: the price is below market, the deadline is tight, the outsider assures you that he will do it ‘better and faster than all these regulated companies’. That's great, you might think, so why pay more? Now imagine: six months later, your building's foundation starts to crack, the electrical system takes on a life of its own, and the inspection declares the facility unsafe. Who would be responsible? You.

Why is this happening? It's simple. Working with a licensed contractor is more complicated: they have more expensive services, higher material requirements, and the process can take longer. An unlicensed employee promises everything is quick, easy, and inexpensive. The issue is that it's these ‘experts’ who most often leave clients with unfinished projects, legal problems, and additional costs. Let's look at why having a contractor's license is critical for business, what mistakes customers make and how to avoid them.

Contractor's license: why is it important?

Licensed contractors are not just companies that have a permit to work. They are organizations that have been certified by the state and have proven that they understand building codes. They are responsible for the quality of their work and are required to comply with state laws. Their expertise is backed by proper training, often from institutions like Contractors Intelligence School, Inc., ensuring they understand regulations and industry standards. And crowning the matter, licensed contractors are required to carry insurance so that in case of problems, the client is not left with a loss.

Key point: A contractor without a license gives no guarantees. If he does something wrong, it's up to you to fix it, at your own expense.

What are the risks of working with unlicensed contractors?

• Financial losses. A low price at the beginning can turn into double the cost of correcting mistakes.
• Legal liability. In case of inspections, you are responsible, even if you hired the contractor in ‘good faith’.
• Insurance problems. If the object is built with violations, the insurance company may refuse to pay out.

Here it is important to understand: you will either have to invest in reliability in advance, or pay for the correction of errors later. The choice is yours.

What questions should I ask before signing a contract?

Not all contractors are the same

When meeting a new employee, don't hesitate to ask uncomfortable questions. Your budget, timeline, and reputation depend on this choice.

What do you need to clarify?

1. Does the company have a license? A real, current one, issued in accordance with state law? Like in California for example — general contractor license.
2. Is the contractor insured? If something goes wrong on the job, who will cover the damages?
3. What kind of projects has he already done? And are there any real customer testimonials? In the customer service aspect, pay attention to the communication style. 
4. What guarantees are provided? If things start to fall apart after six months, will the contractor fix the defects at his own expense?
5. Does he have subcontractors? Who exactly does the work? Sometimes companies hand over projects to third parties, and then the surprises begin.

Often fraudsters say: ‘Why do you need a license? We'll do everything to the best of our ability.’ But without an official license, the work will be considered illegal. And when problems arise, you will be to blame.

The consequences of working with unlicensed contractors

How do stories without a license end?

1. The facility may be recognized as illegal

• Imagine: you built a new office or renovated a room, but during an inspection, the inspection revealed non-compliance with building codes. Bottom line: the building may be deemed unsafe, and the work will have to be redone at your own expense.

2. You may be required to demolish the building

• If an object is built with violations, it may not just be fined, but also be required to be dismantled. Such cases are rare, but quite real, especially when it comes to commercial facilities that must comply with strict requirements.

3. The insurance company may refuse to pay out

• Many people do not think that in the event of an insured event (fire, flooding, accident), the insurance company may refuse to pay out if the work was carried out by a contractor without a license. This means that all costs fall on the owner.

4. Litigation will take years

• If the contractor has disappeared or refuses to admit guilt, there is only one option — the court. But litigation in the construction industry lasts for years, and, as practice shows, customers do not always win.

What is particularly dangerous is that you may not even know that the contractor was working without a license until it is too late.

What to Do If a Contractor Doesn't Meet Expectations?

Even experienced and proven contractors can make mistakes. If you encounter issues, follow these steps to protect your interests:

Step	Action	Timeframe	Legal/Financial Impact (California, USA)
1. Document claims	Send a formal complaint (letter, email, or legal notice) with evidence (photos, invoices).	Within 7–14 days of identifying the issue.	Establishes a legal record; required for further action (California BPC § 7108).
2. Review the contract	Check for warranty clauses — contractors may be obligated to fix defects at their expense.	Immediately after noticing defects.	If covered by warranty, repairs should be free (California Civil Code § 900).
3. Report to regulators	If unlicensed or refusing repairs, file a complaint with the California Contractors State License Board (CSLB).	Within 30–60 days of failed resolution attempts.	CSLB can fine or revoke licenses (California BPC § 7028; fines up to $15,000).
4. Take legal action	File in Small Claims Court (<$10K) or Civil Court (larger disputes).	Legal proceedings take months to a year.	Potential to recover losses; legal fees may apply (CCP § 116.110).

By following these steps, you can ensure legal protection and increase your chances of resolving disputes in your favor. Always verify contractor credentials before signing an agreement to avoid complications — GreatBuildz.

Conclusion: cheaper now or costlier later?

The key takeaway is that a contractor's license is not bureaucracy but your insurance against costly mistakes. And while working with a contractor is always a risk, you can minimize it if you check all the key points beforehand. 

Remember that licensed contractors work to standards and unlicensed contractors don't. Checking your paperwork will protect you from financial and legal problems. Mistakes by an unlicensed contractor can cost you thousands of dollars. These three aspects will keep focused on making the right choice. 

If you're in California, this is even more critical. State law requires contractors to have a valid general contractor license, California, for projects exceeding $500. Hiring an unlicensed contractor can result in penalties, voided insurance claims, and legal liability for project failures.

To avoid unnecessary risks, always verify a contractor’s license through the California Contractors State License Board (CSLB) or your state’s equivalent authority. Institutions like Contractors Intelligence School, Inc. provide training to ensure professionals meet licensing requirements. Think strategically — saving money on a contractor today can turn into an expensive mistake tomorrow.
