Oklahoma Construction Industries Board (CIB) - licenses plumbing, electrical and mechanical contractors; general contractors are not state-licensed
Oklahoma does not require a state license for general contracting; the CIB licenses the three trades, and an active plumbing/electrical/mechanical contractor license stays inactive until the CIB receives proof of a $5,000 corporate surety bond and $50,000 commercial general liability insurance naming the CIB as certificate holder. Failure to keep the insurance current makes the license inactive. Workers' comp is required for employers with one or more employees, but an employer with five or fewer employees all related by blood or marriage to the employer is exempt.
The state sets a minimum of $50,000 commercial general liability (for an active plumbing/electrical/mechanical contractor). What you actually need is set by the contract in front of you. Most Oklahoma general contractors require one million per occurrence and two million aggregate from their subcontractors, plus additional insured status and a waiver of subrogation.
Workers compensation is required for employers with any employees. Operating without it where it is required exposes the business to penalties and to direct liability for an injured worker's medical costs.
Any vehicle used for business needs commercial auto. A personal policy excludes business use in every state, and it will not cover the tools inside the truck.
General liability never covers your own tools. Inland marine covers them in transit and on site, including theft, which is the most common loss contractors actually file.
Workers compensation is required for employers with any employees.
Workers compensation covers medical costs and lost wages for a work-related injury or illness. It is separate from general liability, which covers injury to other people. If an employee is hurt on a job site in Oklahoma, that is a workers compensation claim, and general liability will not respond to it.
Oklahoma requires a contractor license bond of $5,000 corporate surety bond (active plumbing/electrical/mechanical contractor). A license bond protects the consumer if you fail to complete the work or violate licensing law. It is not insurance and it does not pay a claim made against you, which is why contractors carry both.
Beyond the license bond, bid bonds and performance bonds come up on larger and public work. Bid bonds are typically priced as a percentage of the bid amount rather than a flat fee, so the cost scales with the project.
The state sets a minimum of $50,000 commercial general liability (for an active plumbing/electrical/mechanical contractor). That is a floor for licensing, not a recommendation, and contracts in Oklahoma commonly require more.
Workers compensation is required for employers with any employees.
Yes. The contractor license bond is $5,000 corporate surety bond (active plumbing/electrical/mechanical contractor). It protects the consumer, not you, and it does not take the place of insurance.

The consequences run from losing the contract to losing the license. A general contractor who finds your certificate is not what the subcontract required will typically stop work and withhold payment until it is corrected, and an uninsured loss becomes a personal liability rather than an insurance claim.
Yes. A single policy can list every state you operate in. Pricing is driven by the highest-exposure state on the schedule, so tell us all of them rather than only your home state.
Requirements differ enough by state that it is worth checking before you bid.
