Workers' compensation in Castle Rock: the Colorado rules
Whether Colorado requires workers' comp for your team, what it costs at the 2026 median, and how Castle Rock businesses get covered the same day.
In Colorado, workers' compensation is required from the 1st employee - there is no small-team exemption. The 2026 national median cost is $54 a month.
Castle Rock, Colorado has about 83,213 residents, and carriers price its businesses on trade, payroll and revenue rather than on the town itself.

Workers' compensation is the one coverage where Colorado law, not prudence, sets the floor. In Colorado, workers' compensation is required from the 1st employee - there is no small-team exemption. The national median cost is $54 a month, but the real driver is payroll and job class - office payroll costs cents per hundred dollars, roofing payroll costs dollars.
Unlike general liability, workers' comp is not optional once you cross your state's employee threshold. In Colorado, workers' compensation is required from the 1st employee - there is no small-team exemption. Premiums are quoted per 100 dollars of payroll by job classification, which is why the $54 national monthly median stretches widely across trades.

Typically not covered
- Injuries while intoxicated or on drugs - routinely denied
- Self-inflicted injuries, or fights the employee started
- The commute to and from work - the going-and-coming rule

Common questions
Can I be paying for the wrong class code?
Yes, and it is common: class codes are assigned from your business description, and a vague description lands in a pricier class. Reviewing the code on your declarations page against what you actually do is a five-minute check that owners skip.
Is the cheapest business insurance good enough?
Only if the carrier actually pays claims. Before comparing price, check two public numbers: the insurer's AM Best financial strength rating (A- or better) and its complaint index with state regulators (1.0 is average - lower is better). The difference between a good payer and a bad one is usually a few dollars a month; the difference at claim time is everything.
Is business interruption coverage worth it?
It only pays when a covered physical event - fire, burst pipe - closes your location, but when it pays it replaces the income a closed business is not earning. It comes bundled inside most BOPs rather than as a separate policy.
Does an LLC need insurance too?
Yes - the LLC protects your personal assets from business liabilities, but the business's own assets stay exposed. Insurance pays claims; the LLC just keeps them away from your house. Most owners carry both.
Is business insurance required by law in Colorado?
Two lines can be legally required: workers' compensation once you reach the state employee threshold, and commercial auto liability for business vehicles. General liability is not state-mandated, but leases and client contracts routinely require it.
