Workers' Comp for Residential Remodeling Crews: Class Codes and Cost Drivers

Workers' compensation insurance is mandatory for remodeling contractors with employees in virtually every state. But the premium you pay — and whether you can get coverage at all — depends heavily on how your business is classified, your loss history, and how your crews are structured.

Here's what residential remodelers need to understand before they renew or shop their workers' comp policy.

Class Codes That Apply to Remodelers

Workers' comp rates are set by class code — a numeric designation that groups workers by occupation and associated risk level. Residential remodeling work tends to spread across multiple codes depending on what type of work each employee actually performs.

Code 5645 — Carpentry, dwelling construction: Applies to carpenters on residential projects. One of the most common codes for general remodeling crews.

Code 5183 — Plumbing: Plumbers and plumber's helpers doing residential work. This applies whether your crew does the plumbing or you subcontract it and have oversight responsibility.

Code 5190 — Electrical wiring: Electricians and helpers. Rates here reflect the real injury exposure from electrical work.

Code 5474 — Painting: Residential painters, including prep work, patching, and finish painting.

Code 5480 — Plastering and lathing: Applicable for drywall, stucco, and finishing crews.

Code 5022 — Masonry: Tile setters, stone installers, and masons working on residential remodels.

Code 8742 — Sales and office: For estimators, project managers, and office staff who don't perform manual labor.

The rate per $100 of payroll varies significantly between codes. It's critical that your employees are classified correctly — misclassification that puts office staff in a field code increases your premium; misclassification in the other direction is an audit red flag.

The Experience Mod and What It Means

After three years in business with workers' comp coverage, you'll have an experience modification factor (mod) applied to your base rate. The mod is calculated by your state's rating bureau based on your actual claims history versus what's "expected" for your payroll and class codes.

• A mod of 1.00 means you're average — you pay the published rate.
• A mod below 1.00 (credit mod) means your losses are better than expected — you get a discount.
• A mod above 1.00 (debit mod) means your losses are worse than expected — you pay a surcharge.

For remodeling contractors, the mod is one of the biggest levers on your workers' comp cost. A single lost-time claim — a fall from a ladder, a serious laceration, a back injury from heavy lifting — can significantly move your mod for three policy years.

What Drives Claims in Remodeling

The injury types we see most often in residential remodeling:

Falls from heights. Working from ladders, scaffolding, rooftops, and elevated decking is inherent to remodeling. Falls are the leading cause of fatalities and serious injuries in construction. Safety protocols and proper fall-protection equipment are the most effective cost controls.

Struck-by and caught-in injuries. Power tool accidents, falling materials, and tool malfunctions are common across all trades. Toolbox talks and site organization reduce this exposure.

Overexertion and musculoskeletal injuries. Carrying heavy materials, working in awkward positions, and repetitive motion all contribute to back, shoulder, and knee injuries. These are often chronic, leading to extended lost-time claims.

Lacerations and punctures. Hand and finger injuries from saws, utility knives, and fasteners are frequent. While often less severe than falls, they drive claim frequency.

Controlling Your Workers' Comp Cost

Hire carefully and document training. Your hiring standards and onboarding process directly affect your injury rate. Written safety training records help during audits and can support premium credits with some carriers.

Separate your subcontractors correctly. If you use 1099 subs who carry their own workers' comp, you typically don't owe premium on their payroll. But you need certificates of insurance proving they have their own coverage — carriers audit this at year-end.

Implement a return-to-work program. When a worker is injured, having modified-duty tasks available for light-duty work controls indemnity costs (wage replacement), which is the biggest component of most lost-time claims.

Pay attention to your mod. Work with your agent to understand what's driving your experience mod and whether any claims can be closed or reserved more accurately.

Sole Proprietors and Single-Member LLCs

In most states, sole proprietors and single-member LLC owners can elect to exclude themselves from workers' comp coverage. This reduces your premium but leaves you personally uninsured for on-the-job injuries. If you're the primary laborer in your business, the calculus on this election deserves careful thought.

Getting a Competitive Quote

Workers' comp markets for residential remodelers vary in appetite and pricing. Some carriers specialize in construction risks and price them more competitively than generalist insurers. If your current quote feels high — or if you've had difficulty getting coverage due to loss history — it's worth letting us shop the market.
