Florida construction workers comp cost is built trade by trade: divide payroll by 100, multiply it by the filed or carrier rate for each confirmed class code, then apply experience and policy factors. A roofing crew, electrician and office employee do not cost the same per payroll dollar. Subcontractor records and the final audit can also change the bill. No honest estimate is possible until the work and payroll are separated.
A real trade example
Roofing class code 5551 has a 2026 Florida filed rate of $6.75 per $100 of payroll. If a carrier confirms 5551 and the roofer projects $300,000 in that payroll, the starting manual-premium component is $20,250. That is not the final quote and should not be treated as a promise.
Carrier pricing, experience modification, credits or debits, assessments, expense constants and other terms can move the number. Different construction trades have different rates. The carrier or NCCI must confirm every classification before any calculation is trusted.
Why two contractors pay differently
Picture two remodelers with the same revenue. One has salaried project managers supervising insured subcontractors. The other self-performs demolition, framing and roofing with field employees. Revenue is similar, but rated payroll and work hazards are not.
Loss history separates them further. An experience mod below or above 1.00 can change qualifying premium. A rising experience mod narrows voluntary market options, and Florida's assigned risk market, the FWCJUA, prices in tiers: its best tier is for rated employers with an experience modification below 1.00, no lost-time claims and medical-only claims under 20% of premium, the next tier covers modifications from 1.00 to 1.10 on the same claim criteria, and everything else falls to the highest-priced tier; employers who cannot place coverage voluntarily must show a good-faith effort before using Florida's assigned risk market, usually at a materially higher cost. Contractors pushed out of voluntary options may enter the assigned risk market at a much higher overall cost.
Florida rules make labor records critical
Construction coverage is generally required at the first employee. Sole proprietors and subcontractors are not automatically outside employee treatment, and an owner's exemption applies only to the approved person. Missing employee or subcontractor status can turn a low opening estimate into a large audit balance.
- Keep payroll by employee and confirmed duty.
- Collect certificates before subcontractors mobilize.
- Verify exemptions for the right person, company and dates.
- Match contracts, invoices and payment ledgers.
- Report labor-model changes during the policy year.
Height, equipment and project mix affect placement
Maximum stories, structural work, cranes, demolition, heavy equipment, energized work and storm response help an underwriter decide whether the operation fits. They may not appear as separate line-item charges, but they affect appetite, classification and available terms.
A residential service electrician can present a different submission from an industrial contractor, just as a roof repair shop differs from a high-rise re-roofer. Give maximum exposure, not only the most common easy job.
Deposit premium is not final construction cost
The policy starts with projected payroll and operations. The audit later uses actual reports and books. Growth, overtime, new trades or uninsured subcontract cost may create additional premium. An unrealistic low estimate only delays the cost.
Review payroll against the policy each quarter. When the backlog adds a crew or a general contractor begins self-performing work, update the estimate. A controlled endorsement is easier to budget than a year-end surprise.
Ways to improve cost without misclassification
Confirm codes, maintain eligible payroll separation, close open claims actively, investigate injuries, correct recurring hazards and start renewal early. If loss performance is poor, document specific operational changes with dates and records.
Do not rename roofers as laborers, supervisors or subcontractors to chase a lower number. Misclassification can be reversed at audit and may create compliance consequences.
People Also Ask
Is construction workers comp based on revenue?
Usually payroll is the main exposure base. Revenue helps explain the operation but does not replace payroll.
Does every contractor pay the roofing rate?
No. Each trade must be classified from actual work. The carrier or NCCI confirms the applicable codes.
Why did my construction audit add premium?
Common causes are higher payroll, changed operations, reclassification or unsupported subcontractor records.
