What Is Workers Comp Class Code 6400?
NCCI class code 6400 covers Fence Erection in Florida. This classification is used by workers' compensation carriers to determine premium rates based on the relative injury risk of workers in this occupation. The Florida NCCI rate for code 6400 is $3.70 per $100 of payroll, placing it in the high-risk tier.
Covers fence installation contractors — wood, chain link, vinyl, and ornamental iron. At $5.84/$100, a worker earning $800/week costs $46.72/week in workers comp.
Because code 6400 is a construction classification, Florida law requires workers' compensation coverage from the first employee. Construction employers cannot use the 4-employee threshold that applies to non-construction businesses.
What Does This Rate Mean in Real Dollars?
At $5.84/$100, a worker earning $800/week costs $46.72/week. Annual cost for $120,000 payroll: ~$7,008.

Top Workers Comp Risks for Code 6400
The NCCI rate for this classification reflects the frequency and severity of workers' compensation claims historically filed by workers in this occupation. The primary risks include:
Florida Workers Comp Requirements for Code 6400
Florida Statute Chapter 440 governs workers' compensation requirements. For construction employers classified under code 6400, coverage is required with 1 or more employees — including the business owner unless a valid exemption is on file with the Florida Division of Workers' Compensation.
The Florida Division of Workers' Compensation conducts random job site inspections and can issue an immediate stop-work order if coverage is not current. The penalty is equal to twice the amount of premium that should have been paid, plus $1,000 per day per employee while uninsured.
OSHA Standards That Apply to Code 6400
Workers in this classification are subject to the following OSHA standards. Violations of these standards are the most common triggers for workers' compensation claims in this trade.
OSHA 1926.651(b)
Underground installations: Requires locating and protecting utilities before digging or augering post holes; fence crews must contact 811 and expose utilities safely to prevent strikes to electric, gas, water, or communications lines.
OSHA 1926.600(a)
Equipment (Motor vehicles, mechanized equipment): Covers safe operation of skid-steers, mini-excavators, and post-hole augers used in fence installation, including backup alarms, seat belts, and keeping workers clear of swing/rotation zones.
OSHA 1926.416(a)(1)
Electrical, safety-related work practices: Prohibits work that could contact energized circuits; fence erectors must maintain clearances from overhead lines when carrying long metal sections, setting posts, or operating raised equipment.
OSHA 1926.1153
Respirable crystalline silica (construction): Requires controls, exposure assessments, and housekeeping when mixing/dumping bagged concrete for post footings or dry-cutting/coring concrete or masonry during fence/gate installs.
OSHA 1910.1200
Hazard Communication: Requires SDS access, labeling, and training for Portland cement, post-setting additives, primers, adhesives, and fuels/solvents used on fence jobs.
Florida Stop-Work Order Cases — Code 6400
The Florida Division of Workers' Compensation (DFS) actively enforces coverage requirements. Below are representative enforcement cases involving businesses classified under code 6400.
Hillsborough County (2022): DFS issued a stop‑work order on a fence contractor setting chain‑link at a Brandon auto lot with six installers and no active workers’ comp. Investigators documented seven workdays onsite, triggering a $42,000 daily penalty (6 employees × 7 days × $1,000) plus an estimated $22,000 in unpaid premium for prior operations; assessed at twice that amount ($44,000). Total penalty assessed: about $86,000.
Miami‑Dade County (2023): An eight‑person crew installing aluminum/security fencing at a Kendall condo was found operating without coverage; company had been paying crews in cash for nearly two years. DFS calculated a $32,000 daily penalty (8 employees × 4 days × $1,000) and estimated unpaid premium of ~$40,667 over the prior two years, doubled to $81,334. Total penalty assessed: roughly $113,334.
Polk County (2021): Three installers using a rented skid‑steer auger on a new subdivision perimeter fence in Lakeland were stopped for no workers’ comp. DFS applied a $30,000 daily penalty (3 employees × 10 days × $1,000) and estimated $6,654 in unpaid premium from the prior year, doubled to $13,308. Total penalty assessed: about $43,308.

Why Standard Carriers Decline Code 6400
Many standard insurance carriers restrict or decline coverage for businesses classified under code 6400. Understanding these declination triggers helps you find the right coverage path.
Frequent hand/eye lacerations and punctures from chain‑link, barbed/razor wire, grinders, and cutting tools lead to high claim frequency on 6400, so many standard carriers either decline or surcharge heavily.
Use of augers, post drivers, and skid‑steers creates severe loss potential (caught‑in, overturns) and utility‑strike exposure; carriers are wary of electrocution and trench/void injuries tied to fence post excavation.
Highway‑side and right‑of‑way fencing exposes crews to struck‑by traffic hazards and requires strong DOT/MVR controls; accounts with poor fleet safety or multiple driver violations are commonly declined.
Subcontracted/1099 installation crews without valid Florida WC certificates and weak COI controls cause payroll pickup at audit and unpredictable losses, so underwriters often reject 6400s with heavy uninsured sub use or new ventures with no verifiable safety program.
Common Workers Comp Audit Mistakes for Code 6400
Year-end workers comp audits frequently result in unexpected additional premiums for businesses classified under code 6400. These are the most common audit mistakes to avoid.
Trying to split working owners/foremen between 6400 (field) and 8810 (clerical) based on office hours; in Florida construction, field supervisors must be assigned to a single governing class (6400) unless they are exclusively clerical with proper segregation.
Classifying drivers as 7380 to lower cost; for fence contractors, yard/driver time that includes any field or loading/unloading exposure is typically assigned to 6400 unless there is a dedicated, exclusively driving position with contemporaneous time records.
Leaving out cash per‑diem, subsistence, and untaxed allowances from payroll, and failing to document overtime premium separately; auditors add these back, increasing the 6400 exposure.
Treating 1099 fence crews as exempt subs without valid Florida COIs listing WC, or accepting COIs with wrong class codes/states; at audit, those uninsured labor costs are picked up into 6400 payroll, often retroactively for the full term.
Experience Mod (EMR) & PEO Advantage
Fence erection (6400) sees lots of small but frequent claims—cuts, punctures, strains—and the occasional severe auger or utility‑strike injury; that mix drives experience mods up quickly because frequency weighs heavily. A PEO can place you on a large master policy where pricing isn’t tied to your standalone EMR and bring safety resources (811 dig ticket documentation, auger lockout/guarding, silica controls) and claims management to cut both frequency and severity. With cleaner loss runs under the PEO, your company’s EMR can improve when you move back to a direct policy or when the mod is recalculated for your FEIN.
