Michigan hardware store and lumber yard insurance has to cover several businesses at once. A typical independent store sells thousands of products, rents tools and trailers, fills propane cylinders, runs forklifts in a yard where customers walk, and sends trucks out to job sites. Michigan had 532 hardware stores and 676 other building material dealers in 2024, according to BLS data. The stores that get the best terms are the ones whose insurance program matches everything they actually do.
The short version: Classify your payroll correctly (store, yard and drivers are rated differently), get your suppliers to name you on their vendors coverage, document propane and forklift training, use real rental agreements, and insure your delivery trucks for what they actually do. Those five items are where retail building supply programs usually have gaps.
Store, yard and drivers are different workers' comp classes
How Michigan's workers' compensation manual, published by the Compensation Advisory Organization of Michigan, describes the common classes:
- 8010, Store: hardware and mill supply dealers. Includes sales staff, cashiers, counter staff, stockers, paint color mixers and employees repairing rental equipment. The class expressly includes tool and trailer rental.
- 8232, Building material dealer / lumber yard: yard and warehouse. Limited manufacturing such as cutting to size and threading pipe is included.
- 8058, store employees of a lumber yard or home center. A companion class that can only be used together with 8232.
- 7380, Drivers. Delivery drivers are assigned here, and Michigan's manual doesn't allow one employee's pay to be split between driving and another class.
That last rule catches stores whose yard staff also drive the delivery truck: all of that employee's pay goes to 7380, or to a higher-rated class covering part of their duties. Talk to your agent about how those employees are recorded, because the answer affects your premium and your audit. Voluntary carriers file their own rates and may apply classifications differently, so treat these as how Michigan's manual describes the work. See our post on Michigan class codes.
Product liability when you didn't make the product
Michigan law gives retailers real protection. Under MCL 600.2947(6), a seller other than a manufacturer isn't liable for harm caused by a product unless the seller "failed to exercise reasonable care, including breach of any implied warranty," or made an express warranty the product didn't meet. Two practical lessons follow:
- Watch what your staff promise. "That ladder will hold anything" is the kind of statement that can become an express warranty.
- Get your suppliers' vendors coverage. Ask manufacturers and distributors to add your store as an additional insured on their liability policy. The standard vendors endorsement has exclusions, including products you intentionally change (cutting to size, for example), repackaging or relabeling, warranties the manufacturer didn't authorize, and installation or repair done away from your store.
Your own general liability policy still defends you when you're named in a product suit, so your limits matter. For most of our commercial clients, $1 million per occurrence is the floor, with an umbrella above it. Our distributor and warehouse guide covers supplier contracts and vendors coverage in more depth.
Propane filling and exchange
Propane is one of the first things an underwriter asks about. In Michigan, LP-gas storage and handling falls under rules administered by the Bureau of Fire Services in the Department of Licensing and Regulatory Affairs, which adopt the NFPA 58 Liquefied Petroleum Gas Code (2014 edition). Those rules require plan review at least 30 days before installing any container filling location. NFPA 58 requires employees who handle LP-gas to be trained for their duties, with documented training and periodic refreshers.
What helps your insurance: a filling station installed and approved under the state rules, a written list of who's trained to fill and when, exchange cylinders stored in a proper outdoor cage, and clear rules about refusing damaged or out-of-date cylinders.
Tool and equipment rental
A rental counter changes your liability picture. Under the standard general liability form, "your product" doesn't include property rented to others but not sold, so injuries from rented tools are generally treated as part of your store's operations rather than under products-completed operations. It's still a liability claim against your store, and your carrier should know about the rental counter. A signed rental agreement with clear instructions, a check of the customer's ID, documented inspection between rentals, and a maintenance log are what defend those claims. The rental fleet itself, sitting on your lot or at a customer's site, needs its own property or equipment coverage.
Forklifts around customers
Lumber yards put forklifts and customers in the same space. MIOSHA's powered industrial truck standard (General Industry Part 21) requires training and evaluation before an employee is authorized to operate a forklift, an employer-issued operator permit valid for no more than three years, and refresher training after an accident or near miss. Operators must slow down and sound the horn at cross aisles and other locations where their view is blocked. Those rules protect employees; a customer hit by a forklift or struck by falling lumber is a general liability claim. Marked pedestrian zones, staff loading for customers, and a rule that customers stay clear of operating forklifts are the controls underwriters look for.
Delivery trucks
- Michigan no-fault applies to your trucks. Owners of vehicles required to be registered in Michigan must carry no-fault coverage, and an employee injured while riding in an employer's vehicle generally receives PIP benefits from the insurer of that vehicle, coordinated with workers' comp.
- Size matters for safety rules. Trucks of 10,001 pounds or more can bring federal motor carrier safety rules into play, and Michigan applies many of those rules to intrastate trucks as well. Driver qualification files and annual record reviews are part of that.
- Unloading at the job site. Injury or damage while unloading with a truck-mounted boom or forklift can fall between your auto and general liability policies. Ask how both policies treat loading and unloading.

Frequently Asked Questions
What insurance does a hardware store need in Michigan?
Typically commercial property for the building and inventory, general liability including products coverage, workers' compensation, commercial auto for delivery vehicles, equipment coverage for a rental fleet, crime coverage, and an umbrella. Propane filling, tool rental and forklift operations each affect how the program is underwritten.
Is a hardware store liable for a defective product it sold?
Under MCL 600.2947(6), a Michigan seller that didn't manufacture the product is liable only if it failed to exercise reasonable care, including breach of any implied warranty, or made an express warranty the product didn't meet. The store can still be sued and need a defense, so general liability limits and suppliers' vendors coverage both matter.
Does a store need special insurance to fill propane tanks?
There's no separate propane policy required by state law, but propane filling is an important underwriting item. Michigan's rules adopt the NFPA 58 code, require plan review for a container filling location, and expect trained employees. Carriers want to see that the filling station is approved and that training is documented.
What is the workers' comp class code for a lumber yard in Michigan?
Michigan's manual places lumber yard and warehouse work in 8232, store employees of a lumber yard in the companion class 8058, and delivery drivers in 7380. Hardware stores are generally 8010. Voluntary carriers may apply classifications differently.
Does general liability cover injuries from rented tools?
Injuries from rented equipment are generally a general liability exposure, but they aren't treated as products you sold. Rental agreements, inspections between rentals and maintenance records are important to defending those claims, and the rental equipment itself needs separate property or equipment coverage.
The bottom line
A building supply store's program should be written around its counter, its yard, its rental shop, its propane cage and its trucks, not just its square footage.
