Construction professional liability insurance is a crucial investment for builders, contractors, and other construction professionals. This type of insurance protects against financial losses resulting from errors, omissions, or negligence in the course of their work.
Policy limits and deductibles vary, but typically range from $1 million to $5 million, with deductibles starting at $1,000.
There are several insurance options available, including claims-made and occurrence-based policies.
What Is Construction Professional Liability Insurance?
Construction professional liability insurance is a type of insurance that provides coverage for construction firms in the event of a lawsuit brought against them for negligence in providing services.
This policy is also known as errors and omissions insurance, and it will help provide indemnity for legal costs when facing accusations of negligence or errors.
Contractor and construction mistakes, such as failure to follow a blueprint, can be financially devastating for clients. Contractors' professional liability insurance will help provide coverage for such mistakes.
Professional liability insurance policies are typically written on a claims-made basis, which means the policy must be active when an alleged mistake occurs and when the claim is filed.
Here are some examples of what professional liability insurance covers:
- Failure to deliver promised services
- Negligence in providing services
- Errors and oversights
Who Needs Coverage?
You don't have to be a lawyer or doctor to know that professional liability insurance is a must-have for many professionals. In construction, it's essential for nearly every trade and specialty.
General contractors, roofers, and masons are just a few examples of contractors who can benefit from professional liability coverage. Plumbers, electricians, carpenters, and concrete contractors also need it to protect themselves from financial ruin in case of a lawsuit.
A single lawsuit related to professional negligence can financially ruin a contracting business. That's why it's crucial to maintain adequate E&O coverage, which offers additional protection beyond what general liability insurance provides.
Here are some of the trades and specialties that can benefit from professional liability insurance:
- General contractors
- Roofers
- Masons
- Plumbers
- Electricians
- Carpenters
- Concrete contractors
- Sheet metal contractors
- Painters
- Architects
- Engineers
- Home inspectors
Contractors and Construction Businesses
Contractors and construction businesses need professional liability coverage to protect themselves against lawsuits and financial ruin. A single lawsuit can financially ruin a contracting business, making E&O coverage a must-have.
Almost every trade and specialty in construction has professional liability policies available, including general contractors, roofers, and electricians. Architects and engineers are the only ones who are usually required by law to have this coverage.

Architects & Engineers

These lawsuits can arise from even the smallest mistakes, such as a miscalculation or a missed detail, which can have serious consequences for the project and the professionals involved.
Architects and engineers are often held to high standards, and any perceived failure to meet those standards can result in a lawsuit.

What Does It Cover?
Construction professional liability insurance is a critical safety net for construction companies. It covers the legal costs and settlements arising from claims of professional negligence, errors, or omissions in the services they provide.
Professional liability insurance policies typically cover errors made while performing services, omissions in completed work, negligence in work performed, and incorrect professional advice provided.
A professional liability policy will only cover a contractor for the scope of work they perform within their specialty, and exclusions to coverage are typically based on the risks faced by particular trades.
Here are some examples of what professional liability insurance covers:
- Failure to deliver promised services
- Negligence in providing services
- Errors and oversights
- Design faults, such as structural failures, safety hazards, or project delays
These issues can occur during project planning, design, or execution and might result in financial losses or damage to property for clients. Even minor oversights can lead to significant financial repercussions, potentially jeopardizing the company's stability.
Professional liability insurance can help with court costs, attorney's fees, and judgments or settlements when a client questions the quality of your work. It ensures that construction firms can operate with greater confidence, knowing they have protection against unforeseen mistakes that could lead to costly litigation.
Policy Details
Construction professional liability insurance policies typically cover damages to third parties, including property owners, contractors, and other stakeholders.
The policy's coverage limits can vary, but they often start at $1 million and can go up to $10 million or more, depending on the policyholder's specific needs.
In most cases, the policyholder is responsible for paying the deductible, which can range from $5,000 to $50,000.
The policy's coverage duration can also vary, but it's often valid for one to five years, depending on the policy terms.
Claims Made vs Occurrence Policies
Claims Made vs Occurrence Policies offer different coverage timings for construction companies' liability insurance. A claims-made policy provides coverage only if the policy is active both when an incident occurs and when the claim is filed.
This means that if a policy lapses or is not renewed, the insurance company might not cover any claims made after this period, even if the event happened while the policy was active. This can be a significant risk for businesses with ongoing projects.

An occurrence policy covers any incidents during the policy period, regardless of when the policyholder files the claim. This offers a sense of long-term security since it covers any incidents during the policy period, regardless of the filing date of the claim.
Choosing between these policies depends on a firm's exposure to long-tail claims and risk management strategy. An occurrence policy can be a critical factor in your risk management strategy because it provides reassurance that any incidents during the policy period will be covered, even if the claim is filed later.

Policy Cost
Policy Cost is a crucial aspect of contractor insurance. The cost of a professional liability policy is typically around 1% of annual revenue. This means that if your company earns $100,000 per year, you can expect to pay around $1,000 per year for professional liability insurance.
The actual cost can vary widely depending on factors such as geographical region, trade or specialty, and claim history. A policy underwriter will look at your company's financials to determine the policy cost.

Insurance costs for construction companies and contractors are based on several factors, including the type of construction and contracting services offered, level of experience and risk exposure, and where your business operates.
Here are some key factors that can affect your policy cost:
- Type of construction and contracting services offered
- Level of experience and risk exposure in your field
- Where your business operates
- Policy coverage limits and deductibles
- Number of employees
- Liability claims history
On average, construction companies and contractors pay around $74 per month for professional liability / E&O insurance. This cost can vary depending on the specifics of your business and the insurance policy you choose.
Claims Scenarios
Claims scenarios can play out in various ways, but they often involve a professional's failure to meet expectations.
A contractor may be sued for faulty workmanship, which can lead to costly repairs and damage to their reputation.
A construction manager might be held liable for not properly supervising a project, resulting in delays and financial losses.
Professional liability insurance can help protect against claims, but it's essential to understand the scenarios that may arise.
A scenario involving a builder being sued for not completing a project on time and within budget is a common example of a construction professional liability claim.
These claims can be costly and time-consuming, so it's crucial to have the right insurance in place to protect your business.
