Building Material & Garden Equipment & Supplies Dealers
NAICS 444: Building material and garden equipment dealers — home improvement retail, lumber, and pro contractor supply.
Industry at a Glance
Sector-wide aggregates across all businesses classified under NAICS 444 (2017 classification frame). For specific sub-industries within this sector, see the individual reports below.
Code unchanged in NAICS 2022, but the industry now also includes 454 “Nonstore Retailers”.
Industry Overview
Building material and garden equipment and supplies dealers (NAICS 444) covers retailers selling lumber, hardware, plumbing and electrical supplies, paint, garden equipment, and outdoor power tools to both professional contractors and DIY consumers. The Home Depot and Lowe's dominate with a combined 45%+ share of the roughly $500 billion U.S. home improvement market, operating over 4,000 stores between them. Below these two national chains sit regional operators like Menards (Midwest-focused, privately held by John Menard Jr.), Ace Hardware (a dealer-owned cooperative with over 5,000 locations), and specialty lumber and building supply dealers serving the professional trade.
The pro contractor segment has become the strategic battleground. Home Depot's acquisition of HD Supply and its dedicated Pro ecosystem (including tool rental, job-site delivery, and trade credit) illustrate the shift toward capturing commercial and remodeling contractor spending that historically went through specialty distributors. Lowe's has invested in its Lowe's Pro Supply and MVPs Pro Rewards program to compete for this higher-ticket, repeat-purchase customer. Contractor spend tends to be less seasonal and higher-margin than DIY retail, making it the growth priority for both chains.
The subsector's performance correlates tightly with existing home sales (which trigger renovation spending), mortgage rates, and aging housing stock metrics. The National Association of Home Builders tracks remodeling market conditions, and the Harvard Joint Center for Housing Studies' Leading Indicator of Remodeling Activity is the benchmark forecast tool. Garden equipment and outdoor living have benefited from sustained interest in outdoor spaces, with Husqvarna and Deere driving the transition from gas-powered to battery-electric outdoor power equipment — a shift accelerated by California Air Resources Board (CARB) regulations banning small off-road engine sales starting in 2024.

Industry Trends
Home Depot's Pro ecosystem — combining HD Supply, tool rental, job-site delivery, and trade credit — is designed to capture a larger share of the estimated $450 billion professional contractor market that historically flowed through specialty distributors.
California Air Resources Board (CARB) regulations banning new small off-road engine equipment sales from 2024 are accelerating the shift to battery-electric outdoor power equipment from Husqvarna, EGO (Chervon), and Deere across garden equipment retail.
Lumber price volatility — which saw framing lumber futures swing from $350 to over $1,700 per thousand board feet between 2020 and 2022 — has forced dealers to adopt more sophisticated inventory management and hedging approaches.
Ace Hardware's cooperative model is gaining independent dealer locations as owners seek the purchasing scale of a national brand while retaining local ownership and community positioning against the big-box chains.
The Harvard Joint Center for Housing Studies' Leading Indicator of Remodeling Activity projects moderate growth as aging housing stock (median U.S. home age now exceeds 40 years) sustains replacement and renovation demand despite mortgage rate headwinds.

Frequently Asked Questions
What is NAICS 444? ▾
NAICS 444 classifies retail establishments selling building materials, hardware, lawn and garden equipment, and related supplies. It includes home improvement centers, lumber yards, paint and wallpaper stores, hardware stores, and outdoor power equipment dealers. The subsector is distinct from construction material wholesale distribution (NAICS 4233) and serves both professional contractors and DIY consumers through retail storefronts.
How do Home Depot and Lowe's compete for professional contractor business? ▾
Home Depot has built a dedicated pro infrastructure through its acquisition of HD Supply, a nationwide tool rental fleet, job-site delivery logistics, and a trade credit program. Lowe's counters with its MVPs Pro Rewards program and Lowe's Pro Supply. Both chains are investing in dedicated pro service desks, expanded commercial product lines, and digital ordering platforms designed to compete with specialty distributors like ABC Supply and Watsco for contractor wallet share.
What drives demand cycles in this subsector? ▾
Existing home sales are the single strongest demand driver — buyers renovate within 12-18 months of purchase. Mortgage rates influence transaction volumes, aging housing stock creates replacement demand, and consumer confidence affects discretionary project spending. The pandemic triggered an unprecedented spike as homebound consumers redirected travel and entertainment spending into home improvement, creating a pull-forward of demand that is now normalizing.
How is the battery-electric outdoor power equipment transition affecting dealers? ▾
CARB's ban on new small off-road gas engine sales in California starting 2024 is accelerating a national transition that Husqvarna, EGO, and Deere are already driving with lithium-ion product lines. Dealers are allocating more floor space to battery platforms, training staff on different product features, and managing the transition from a service revenue model (gas engine repair) to a battery replacement and accessory model.
What role do independent hardware stores and cooperatives play? ▾
Ace Hardware, True Value (acquired by Do it Best in 2024), and other cooperatives allow independent store owners to access national purchasing scale, private-label products, and marketing programs while maintaining local ownership. Ace's model has proven resilient, adding net new locations annually by attracting owners who prefer community-scale retail over big-box formats. Independent dealers also dominate the specialty pro lumber and building supply segment in markets too small for Home Depot or Lowe's.
