Class Code 0042: Landscaping Operations — CA Workers Comp Guide

What Class Code 0042 Covers

Class code 0042 applies to landscaping maintenance operations servicing both commercial and residential properties. Covered work includes routine lawn mowing, edging, and blowing; shrub and hedge trimming; tree and plant pruning (up to the limits of the code); seasonal planting of annuals and perennials; leaf removal and yard cleanup; drip and sprinkler irrigation system maintenance and minor repairs; mulching and topdressing; and weed control — both manual and chemical application.

The defining characteristic of 0042 work is maintenance: the landscape already exists and employees are engaged in keeping it healthy, trimmed, and clean. If crews arrive at a property with established grounds and leave with the same grounds in better condition — rather than fundamentally altered — the work belongs in 0042.

Important exclusions: 0042 does not cover the installation of hardscape features (patios, walkways, retaining walls), major grading or soil amendment projects, installation of new irrigation systems from scratch, or large-scale planting installation that reshapes a landscape. Those activities belong in code 6217 (Landscaping — Gardening & Maintenance with Construction Elements) or other construction codes depending on scope.

Who This Code Applies To

The typical 0042 employer is a maintenance-focused landscaping company with recurring service contracts — commercial property maintenance (office parks, retail centers, HOA common areas), residential maintenance accounts, or municipal grounds maintenance contracts. Crew members doing route-based maintenance work are the core 0042 employees.

Supervisors and foremen who ride routes and perform hands-on work alongside maintenance crews are typically coded 0042. Office staff who schedule routes, manage billing, and handle customer service are coded 8810 (clerical). Drivers operating landscape trucks between job sites may require separate consideration depending on the nature of the truck operation.

Chemical applicators — employees with a California Pest Control Advisor license who apply herbicides, fertilizers, or pesticides — are often coded separately from general maintenance workers, though many California carriers will accept them under 0042 if chemical application is incidental to the overall maintenance scope rather than the primary business activity.

WCIRB Advisory Rate and Premium Calculation

At $6.82 per $100 of payroll, code 0042 generates substantial premium relative to lower-hazard office codes. A landscaping company with 12 maintenance employees averaging $42,000 annually generates significant WC cost:

• Total maintenance payroll: $504,000
• Manual premium: ($504,000 ÷ 100) × $6.82 = $34,373
• With 1.00 ex-mod and 1.05 carrier LCM: approximately $36,092
• Plus CA surcharges (~3.5%): approximately $37,355 total

An ex-mod above 1.00 — common in landscaping operations that have had prior claims — multiplies directly against manual premium, making claims management and return-to-work programs critical cost drivers. A landscaping company with a 1.25 ex-mod on the above example pays over $9,000 more annually than a competitor with a 1.00 ex-mod doing identical work.

Payroll caps for working owners vary by insurer. Sole proprietors and partners can exclude themselves from coverage; corporate officers with less than 100% ownership must be covered unless they hold a qualifying exclusion election. Given that owner payroll is often high, understanding exclusion options represents a meaningful premium lever.

0042 vs. 6217: The Critical Distinction

The most consequential classification question for California landscaping employers is whether work belongs in 0042 (maintenance) or 6217 (landscaping with construction elements). The rate difference — 0042 at $6.82 vs. 6217 at approximately $9-10/100 depending on carrier — can represent tens of thousands of dollars annually for larger operations.

Work that stays in 0042: Mowing, trimming, pruning, weeding, leaf removal, seasonal planting of small plants from nursery containers, mulching, irrigation head replacement and minor repair, fertilizing.

Work that shifts to 6217: Installation of new irrigation systems involving trenching; installation of hardscape (concrete, pavers, decomposed granite); significant grading or earthwork; installation of retaining walls; large-scale mass planting projects involving equipment and soil amendment; sod installation covering large areas involving equipment.

WCIRB auditors focus on this distinction during policy audits. Employers who perform both maintenance and construction-type installation should maintain separate records for each type of work to support a proper payroll split. If records are not maintained, auditors will typically apply the higher rate to all disputed payroll.

Heat Illness: Cal/OSHA’s Top Enforcement Priority for Landscaping

California’s outdoor heat illness prevention standard (Title 8 CCR 3395) applies directly and vigorously to landscaping operations. Cal/OSHA has made outdoor heat illness enforcement a sustained priority, and landscaping employers are among the most frequently cited industries.

Requirements include: providing fresh, cool water (at least 1 quart per hour per employee); shade structures available and accessible when temperatures reach 80°F; mandatory 10-minute cool-down rest periods in shade when temperatures reach 95°F; a written Heat Illness Prevention Plan; and supervisor training on heat illness recognition and response. High-heat procedures must be implemented when temperatures hit 95°F — these include pre-shift briefings, mandatory buddy systems, and more frequent rest periods.

Insurance carriers increasingly ask about heat illness prevention programs during underwriting. Employers with documented programs, training records, and water/shade protocols receive more favorable underwriting treatment than those without. Cal/OSHA citations for heat illness violations are also reportable to carriers and can affect coverage terms.

Typical Injury Types in 0042

Lacerations and punctures from powered equipment — mower blades, string trimmers, hedge trimmers, chain saws — represent the most frequent claim type. Blade contact injuries, while often thought of as minor, can result in tendon damage, nerve injury, or amputation requiring significant medical care.

Struck-by injuries from flying debris are common in mowing operations. Rocks, sticks, and other debris ejected by mower blades can cause serious eye injuries and lacerations to both the operator and bystanders. Eye protection compliance is a key safety metric for underwriters reviewing landscaping accounts.

Heat illness — ranging from heat cramps and heat exhaustion to heat stroke — is the most severe acute hazard. Fatal heat stroke cases in California landscaping workers have led to major Cal/OSHA enforcement actions and large insurance claims.

Musculoskeletal injuries from repetitive motion (trimming, raking, shoveling), awkward postures (working on slopes), and manual material handling (moving bags of soil, mulch, plant material) generate a consistent stream of back, shoulder, and knee claims.

Pesticide and chemical exposure injuries, while less frequent, can result in serious illness claims when herbicide or pesticide safety protocols are not followed — particularly relevant for operators applying glyphosate-based products or other regulated chemicals.

Underwriting Considerations

Landscaping is a class that carriers approach with meaningful scrutiny. High claim frequency from smaller injuries, combined with outdoor heat exposure and equipment hazards, makes the class volatile. Carriers want to see: five years of loss runs, documentation of Cal/OSHA compliance (particularly heat illness), equipment maintenance logs, and evidence of return-to-work programs.

Operations serving exclusively commercial accounts (office parks, retail, HOA) are often viewed more favorably than mixed commercial/residential operations, because commercial accounts tend to have better site conditions and fewer one-off hazardous conditions. Tree service operations mixed in with landscaping maintenance significantly affect underwriting — carriers may want tree work separately quoted or may exclude it entirely.

For new landscaping businesses without loss history, carriers will price conservatively. Establishing a safety program, obtaining a Cal/OSHA poster, and documenting safety training from day one builds the underwriting file that leads to more competitive renewal pricing in years 3-5.

Carriers Active in Code 0042

ICW Group is the dominant carrier for California landscaping accounts and has developed deep expertise in this class. The Hartford and Travelers compete for mid-to-large landscaping operations with strong safety programs. EMPLOYERS Insurance is active for smaller landscaping operations under $200K in premium. State Compensation Insurance Fund (State Fund) provides coverage as the carrier of last resort and actively writes small landscaping accounts that admitted carriers decline.

AmTrust and Employers Holdings write landscaping through their small-business programs. For larger landscaping operations with more complex exposures, Zurich and Liberty Mutual are available but prefer accounts with documented safety programs, clean loss histories, and total premiums above $50,000. Applied Underwriters has specialty landscaping programs available through select brokers.
