Which policies are required for general contractors in Colorado?
General liability insurance
If you have a physical location with a commercial lease, your property manager may require you to purchase general liability insurance.
General liability insurance can protect your business from expenses associated with common mishaps, such as customer property damage or bodily injury.
Workers' compensation insurance
The state of Colorado requires all businesses with employees, including general contractors, to provide workers’ compensation insurance, which covers lost wages and medical bills for work injuries.
Sole proprietors and independent contractors should also consider purchasing workers' compensation to protect themselves in the event of an accident or injury while on the job. While it isn't mandatory for single-person businesses, it is highly recommended.
Failing to provide workers' comp in Colorado for employees, with few exceptions, can result in fines or other corrective action against the business.
Commercial auto insurance
If your business owns a vehicle, you likely need to purchase commercial auto insurance to meet state requirements. Auto coverage is required in Colorado for all company-owned business vehicles.
Commercial auto insurance protects your vehicles, employees, and business in the event of a vehicle accident.
Colorado requires the following minimum coverages for businesses:
- $25,000 per person bodily injury liability
- $50,000 per person bodily injury liability
- $15,000 per accident property damage liability
If you use leased, rented, or personal vehicles for company purposes, you'll instead need a hired and non-owned auto (HNOA) policy.
Surety bonds
Licensure requirements in Colorado sometimes include a surety bond, depending on the type of work you do and your location. Denver general contractors, for example, are required to carry a $50,000 surety bond.
A surety bond guarantees reimbursement for the client if a general contractor fails to fulfill the terms of a contract or adhere to building codes. Common types of surety bonds include bid bonds, performance bonds, and payment bonds.

When do you need a general contractor business license in Colorado?
Colorado general contractors are not required by the state to carry a license. However, general contractors may still require a license depending on the work they do and their location.
Businesses in Colorado are additionally not required at the state level to carry a license, but certain industries and professions may carry specific licensing requirements, such as electricians, roofers, and landscapers.
Colorado licenses fall into three categories: Class A, Class B, and Class C. Each license has rules and restrictions about the type of work that can be performed and the types of buildings that can be modified.
Colorado cities each carry different requirements for their general contractors. For example, Denver requires contractors to obtain a supervisor certificate (or employ someone who has one), and apply for a license with the city before operating.
Aurora, on the other hand, requires contractors to obtain an International Code Council (ICC) certification, pay a fine, and submit an application before providing general contracting services within the city.
Check your city and county requirements before undertaking a construction project to ensure that you and your employees are protected in the event of a workplace injury or other issue.
