Can Plumbing Go Under Class Code 91340? The Truth

Navigating the complex world of commercial insurance can feel like trying to fix a leak with duct tape—frustrating and potentially messy if done incorrectly. Many small business owners in the trades often ask, “Can plumbing go under class code 91340 general liability?” hoping for a simpler or cheaper classification. The short answer is generally no, and using the wrong code can lead to severe financial penalties or denied claims. In this guide, we will break down exactly what Class Code 91340 covers, why it doesn’t fit professional plumbing work, and how you can ensure your business is properly protected without overpaying.

What Is NCCI Class Code 91340?

To understand why plumbing usually doesn’t fit here, we first need to define what this code actually represents. In the insurance industry, particularly within the United States, the National Council on Compensation Insurance (NCCI) sets standard classification codes. These codes help insurers determine the risk level associated with a specific type of work.

Class Code 91340 is typically defined as “Store or Office – All Employees & Salespersons.”

This classification is designed for businesses that operate primarily in a retail or administrative capacity. It assumes that the employees are not engaged in manual labor, construction, installation, or repair work at customer sites. Instead, it covers clerical staff, salespeople, and managers who work in a fixed location like an office or a showroom.

Key Characteristics of Code 91340:

• Low Physical Risk: The primary hazards are slips, trips, and falls within an office environment.
• No Manual Labor: It explicitly excludes employees who perform installation, repair, or construction services.
• Fixed Location: The work is performed at the employer’s premises, not at various job sites.

If your plumbing business involves sending technicians to homes or commercial buildings to fix pipes, install water heaters, or unclog drains, you are not operating under the risk profile of 91340.

Why Plumbing Does Not Fit Under General Liability Code 91340

The core issue lies in the concept of risk exposure. Insurance premiums are calculated based on the likelihood of a claim being filed. A plumber working on a high-rise building faces significantly different risks than a receptionist sitting at a desk.

1. The Nature of the Work

Plumbing is classified as a trade or contracting service. It involves:

• Working with tools and heavy equipment.
• Exposure to water damage liabilities.
• Potential for bodily injury to third parties (e.g., a client slipping on water from a leak you missed).
• Working at heights or in confined spaces.

Class Code 91340 assumes none of these activities occur. If an insurer discovers that a “store” employee was actually installing pipes at a job site, they may view this as material misrepresentation.

2. The “Separate Store” Exception

There is a narrow scenario where a plumbing company might have some employees under 91340, but not the plumbers themselves. If you own a large plumbing supply showroom where customers walk in to buy fixtures, the sales staff working exclusively in that showroom might be classified under 91340 (or a similar retail code). However, the licensed plumbers who leave the store to perform work must be classified under a contracting code.

Expert Insight: According to industry standards, mixing operational roles under a low-risk code like 91340 is one of the most common audit findings. Insurers expect a clear separation between clerical/retail staff and field technicians.

The Correct Class Codes for Plumbing Businesses

If 91340 is incorrect, what should you use? While codes can vary slightly by state (as some states do not follow NCCI guidelines), the most common classifications for plumbing are:

Why Code 5183 is the Standard

Code 5183 accounts for the higher liability associated with plumbing. It factors in the risk of water damage, which is one of the most frequent and costly claims in the home services industry. By using the correct code, you ensure that if a pipe bursts after your team leaves, your general liability policy is more likely to respond appropriately because the risk was properly underwritten.

For more detailed definitions on how these industries are categorized, you can refer to general industrial classification standards on Wikipedia.

Risks of Misclassifying Your Plumbing Business

Using Class Code 91340 for your plumbing operations might seem like a way to lower your premiums initially, but the long-term consequences can be devastating.

1. Audit Bills and Back Premiums

Insurance policies are subject to annual audits. If the auditor finds that your payroll was classified under 91340 but the work performed was plumbing (Code 5183), they will reclassify the payroll.

• Result: You will owe the difference in premium, plus interest. Since plumbing rates are significantly higher than office rates, this bill can be shocking.

2. Claim Denials

This is the most dangerous risk. If you file a general liability claim for a job-site accident, the insurer will investigate the classification.

• Scenario: A plumber damages a client’s hardwood floor with a leaking pipe.
• Outcome: If the insurer determines the employee was misclassified as “office/store” staff, they may deny the claim entirely, arguing that the premium paid did not cover the risk incurred. You would then be personally liable for the damages.

3. Policy Cancellation

Repeated misclassification or failure to disclose the true nature of your business can lead to non-renewal or cancellation of your policy. This makes it difficult and expensive to secure insurance in the future.

How to Properly Classify Your Plumbing Business: A Step-by-Step Guide

Ensuring you have the right coverage doesn’t have to be complicated. Follow these steps to optimize your general liability classification.

Step 1: Segment Your Payroll

Do not lump all employees into one bucket. Separate your payroll records into:

• Field Technicians/Plumbers: Those who perform the actual work.
• Clerical Staff: Those who handle billing, scheduling, and admin in the office.
• Sales Staff: Those who estimate jobs but do not touch tools.

Step 2: Verify State-Specific Codes

While NCCI is used in most states, California, New York, New Jersey, and others have their own bureaus.

• Action: Check with your state’s workers’ compensation bureau or insurance agent to confirm the exact code number (e.g., CA might use a different numeric sequence than TX).

Step 3: Document Job Descriptions

Keep clear job descriptions on file.

• Example: “John Doe – Senior Plumber. Duties include pipe installation, leak repair, and customer site visits.”
• Example: “Jane Smith – Office Manager. Duties include answering phones and processing invoices. No field work.”

Step 4: Communicate with Your Agent

Be transparent. Tell your insurance broker, “We have two office staff and five field plumbers. Please ensure the field staff are coded correctly for plumbing installation and repair.”

Step 5: Review Annually

Before your policy renewal, review your operations. Did you start doing HVAC work? Did you stop doing new construction? Changes in services require changes in classification.

FAQ Section

1. Can I use Class Code 91340 if I only sell plumbing parts?

If your business is strictly a retail store selling plumbing supplies and you do not offer installation or repair services, then yes, a retail or store code like 91340 (or a more specific retail hardware code) may be appropriate. However, if you offer “installation included” with purchases, you likely need a contracting code as well.

2. What happens if I accidentally used the wrong code last year?

Don’t panic, but act quickly. Contact your insurance agent immediately. It is better to self-correct before an audit discovers it. You may owe some back premium, but it shows good faith and helps protect your coverage status.

3. Is General Liability the same as Workers’ Compensation classification?

Not exactly, but they are closely linked. While this article focuses on General Liability (GL) implications, NCCI codes are primarily used for Workers’ Comp. However, GL insurers often look at the same operational risks. Ensuring your Workers’ Comp codes are correct usually helps align your GL classification. Always verify both with your provider.

4. Why is plumbing insurance more expensive than office insurance?

It comes down to probability and severity. Plumbers work in unpredictable environments (other people’s homes), use tools that can cause injury, and work with systems that can cause massive property damage (water). Office workers face minimal third-party liability risks. Therefore, the premium per $1,000 of payroll is higher for plumbers.

5. Can I bundle my office staff and plumbers under one code to save money?

No. Insurance regulations strictly prohibit “blending” high-risk and low-risk employees into a single low-risk code. This is considered fraud. You must split the payroll according to the actual duties performed by each employee.

6. Does the size of my plumbing business affect the class code?

No, the class code is based on the type of work, not the size of the company. Whether you are a solo operator or a company with 50 plumbers, the operational risk remains the same, so the class code (e.g., 5183) remains the same. However, larger companies may qualify for experience modification factors that lower the final rate.

Conclusion

So, can plumbing go under class code 91340 general liability? For any business performing actual plumbing installation, repair, or service work, the answer is a definitive no. Class Code 91340 is reserved for low-risk retail and office environments. Using it for plumbing operations exposes your business to audit bills, claim denials, and potential policy cancellation.

By correctly classifying your field staff under codes like 5183 and your administrative staff under 8810, you ensure that your business is compliant, protected, and positioned for long-term success. Don’t gamble with your coverage; take the time to review your classifications today.
