Coin-Operated Laundries and Drycleaners (U.S.) — NAICS 812310

An investor's primer. NAICS (North American Industry Classification System) 2022 code 812310. Core figures are the most recent official federal statistics; forward-looking statements are labeled as judgments, not facts.

1. Overview

This is the laundromat business — the self-service, coin- and card-operated stores where people wash and dry their own clothes — plus the closely related "route" companies that install and service self-service machines inside apartment buildings, condos, and dormitories.[1] It is one of the classic small-business, cash-flow industries: high upfront equipment cost, then years of steady, largely passive income from machines that run with little labor.

Why it matters to an investor. Demand is remarkably stable — people wash clothes in good times and bad — and a well-run store can throw off cash with net margins often in the 20–35% range once the equipment is paid down.[8] It is widely treated as recession-resistant, even mildly counter-cyclical: when money is tight, households postpone buying their own washer and use the laundromat instead.[6] The trade-off is that it is capital-intensive, slow-growing, local, and exposed to one big input cost — water, sewer, and gas. The core question at every site is the same: can it generate durable cash flow after rent, utilities, labor, maintenance, debt service, and eventual equipment replacement?

Public vs. private ways in. There is essentially no pure-play public laundromat operator to buy — the storefront operators are private. Public-market investors get exposure one step removed, through the equipment makers, distributors, chemical suppliers, and franchise brands that sell into the industry. For most people this is a private-market industry: you buy or build a store, buy a franchise, or acquire a route/multifamily service business.

2. What it is and how it's structured

Scope. NAICS 812310 covers establishments that (1) run self-service laundry and drycleaning facilities for customers to use on-site, and/or (2) supply and service self-service machines placed in locations run by others — apartments, condos, and dorms.[1] Two very different business models sit inside the same code:

• Storefront laundromats — retail stores, typically 1,000–5,000 square feet, where customers do their own wash. Many are unattended or lightly staffed and absentee-owned.[9] This tier is highly fragmented — mostly single-store owner-operators.
• Route / multifamily operators — companies that own the machines in apartment and dorm laundry rooms and split the revenue with the property owner. This tier is capital-heavy, contract-driven, and consolidated into a few large national players.[16][17]

Despite the name, true coin-operated self-service drycleaning has essentially disappeared; the code today is overwhelmingly laundry (wash and dry). "Coin-operated" is also increasingly a misnomer — the industry is converting to cards and mobile-app payments.[6]

Ownership is layered. At one site the property owner may own the building, a private laundry platform may own or lease the machines, a route operator may collect and service them, and a franchisor may supply the brand and systems — while a local entrepreneur runs the customer-facing store.

What it EXCLUDES (adjacent NAICS codes). This code is narrower than the everyday phrase "laundry and dry cleaning":[1]

• 812320 — Drycleaning and Laundry Services (except Coin-Operated): staffed dry cleaners and drop-off / wash-dry-fold shops where employees do the cleaning. This is the traditional dry-cleaner storefront — a separate, larger, and structurally declining industry (see §9).
• 812331 — Linen Supply: renting and laundering table linens, uniforms, and towels supplied to businesses.
• 812332 — Industrial Launderers: laundering work uniforms, floor mats, and shop towels for industrial clients.
• 333310 — Commercial and Service Industry Machinery Manufacturing (commercial laundry equipment) and 335220 — Major Household Appliance Manufacturing (home washers and dryers) are the equipment codes. That is where several of the public companies actually sit.

Ownership mix. Storefronts: tens of thousands of independent owner-operators, plus a growing layer of franchises. Route/multifamily: dominated by two large private-equity-backed nationals (CSC ServiceWorks and WASH) with a tail of regional operators.[16][17]

3. How big it is

Our ground-truth federal figures for NAICS 812310 (employer businesses — those with paid staff):

CBP = County Business Patterns; EC = Economic Census; SBA = U.S. Small Business Administration. Note the vintages differ — receipts and firm counts are 2022, while establishment and payroll counts are 2023 — so these should not be read as a clean single-year series. The ~$505,000 average is also pulled up by the large route operators inside the code; a typical single storefront runs well below it (see §5).

Concentration. The top four firms account for 30.8% of industry revenue, the top eight for 33.5%, the top 20 for 37.5%, and the top 50 for 42.4%.[3] (These are revenue shares, not profit shares, and exclude nonemployer businesses.) The Herfindahl-Hirschman Index (HHI), the standard concentration measure, is suppressed in the federal data, so we do not state it.[3] Read carefully: those ratios look moderately concentrated only because the large route operators capture a big slice of the code's dollars. The storefront half of the industry is far more fragmented than the four-firm ratio (CR4) suggests.

The undercount caveat (important here). The federal figures above count only employer establishments. Laundromats are the textbook case of a business that often has zero paid employees — unattended, absentee-owned, cash-in / cash-out.[9] Those businesses are counted separately, if at all, in the Census Bureau's Nonemployer Statistics, not in County Business Patterns.[5] Our stats file contains no 812310 nonemployer total, so we do not state a full-economy count — but the true number of laundromat businesses is well above the ~10,890 employer establishments. The Coin Laundry Association (CLA), the industry's trade group, has long put the total in the ~20,000–35,000 range.[6] Employment (41,351) is similarly low by design — labor is not the main input here, machines are. Treat the federal count as a floor, not a full census.

Sizing note — don't conflate categories. The ~$5.5 billion federal figure and the CLA's "nearly $5 billion" both describe self-service laundry (812310).[3][6] Larger market-research numbers you may see — e.g., ~$15.75 billion for "U.S. laundry facilities and drycleaning services" — bundle in the staffed dry cleaners of 812320 and are not comparable to this code alone.[29]

4. The investable universe

There is no listed pure-play laundromat operator. Public exposure comes from the equipment, consumables, franchise-brand, and adjacent-services layers; the storefront and route operators are private.

Public companies (equipment / consumables / brand layers)

Two large uniform/linen names — Cintas (NASDAQ: CTAS) and UniFirst (NYSE: UNF) — are frequently grouped with "laundry," but their business is uniform, linen, and industrial laundering (NAICS 812331/812332), outside 812310. Treat them as adjacent-ecosystem exposure, not this code.[13][14]

5. How the money works

A self-service laundry is best understood as a real-estate-plus-machine-utilization business — an annuity with a heavy upfront cost.

Storefront unit economics. Building or re-equipping a modern store runs roughly $300,000 to $1.5 million, then years of thin-labor cash flow follow.[9] The core operating metric is the turn (turns per day, TPD) — how many wash cycles a machine completes per day. Revenue ≈ machines × turns per day × vend price × 365. Owners obsess over turns because a single lost daily turn across a bank of washers meaningfully dents annual revenue.[8]

• Revenue per store: commonly $200,000–$500,000/year; the federal average across all employer establishments is ~$505,000, but that average is lifted by large route operators.[3][8]
• Cost structure: dominated by utilities — water, sewer, gas, electricity — at roughly 20–40% of revenue, then rent and common-area charges, equipment debt service, repairs and parts, insurance, and payment processing. Labor is small (many stores are unattended).[8] Total operating costs typically run 65–80% of revenue.
• Net margins: ~20–35% for a well-run store.[8]
• Add-on revenue: attended stores layer on wash-dry-fold (WDF) service and pickup-and-delivery (PUD), plus vending — higher-margin, labor-driven revenue that also smooths demand.

Self-service laundries generally collect payment before service and carry little inventory or accounts receivable — a structural cash-flow advantage the CLA highlights; WDF and PUD add labor, routing, and working-capital complexity.[6] The metrics operators and buyers actually watch: same-store sales (SSS, split into price vs. volume), turns per day, revenue per machine and machine uptime, utility cost per load, rent/common-area maintenance (CAM) as a share of sales, WDF pounds per labor hour, route density and revenue per stop, replacement capital spending, and store-level cash flow and return on invested capital (ROIC).

Route / multifamily economics. A different game: the operator installs machines in a building's laundry room under a multi-year lease and shares the coin/card revenue with the property owner. What matters is machines in service, route density (machines per technician), and contract retention. It is an infrastructure-services model — steady and contracted, but capital-hungry and sensitive to whether new apartments are built with in-unit laundry (which removes the room entirely).[16][17]

Real estate. Many owners separate the two assets — they own (or lease) the building and run the laundromat as the tenant. The store is valued on its cash flow; the box is valued like commercial real estate on a cap rate (net operating income, NOI, ÷ purchase price).[21]

What a business changes hands for. Single-store laundromats typically sell for ~3x–5x SDE (seller's discretionary earnings — the owner's total cash benefit) or ~4x–6x EBITDA (earnings before interest, taxes, depreciation and amortization) for multi-store operators.[21] Higher multiples go to stores with strong turns, card/app payment systems, newer equipment, and long, favorable leases. Buyers are heavily SBA-loan-financed individuals in the sub-$500K range, with family offices and search funds active higher up.[21] Because these deals are private, diligence should reconcile tax returns, bank deposits, card reports, coin collections, machine telemetry, utility bills, lease terms, permits, and maintenance history — the CLA specifically recommends using machine-usage and utility-consumption data to test reported revenue.[7]

6. What drives demand

• Renters without in-unit laundry. The single biggest driver. Roughly 60–70% of laundromat customers are renters who lack their own washer/dryer.[9] Demand tracks the renter share of housing, urban density, and apartment living.
• Housing stock and homeownership rate. More renters and more older multifamily buildings (built without in-unit hookups) expand the base; a shift toward homeownership or new units with in-unit laundry shrinks it.
• Population and household formation in dense metros, which skew toward laundromat-using households.
• Large-capacity demand — comforters and bulky items that home machines can't handle keep even homeowners coming in.
• Non-cyclicality / mild counter-cyclicality. Clean clothes are non-discretionary; in downturns some households defer buying home machines and use laundromats more. It is defensive, not perfectly recession-proof — customers can cut frequency, defer bulky loads, or trade down to cheaper locations.[6]
• Convenience economy. Rising demand for wash-dry-fold and delivery adds a growth layer on top of flat self-service volume.
• Payment modernization. Card and app conversion lifts throughput, adds machine-availability notifications, and lets owners raise prices more easily than with fixed coin slots — expanding revenue per machine.[6]

Note: utility and water costs are an input-cost driver of margins, not a demand driver — covered under risks. And the drycleaning side of this industry's name is more discretionary, driven by professional clothing, weddings, travel, and income; work-from-home and casual dress are structural headwinds there (see §9).

---

7. Regulation

Day-to-day laundromats are lightly regulated compared with most industries — local business licensing, zoning, building/fire/plumbing/electrical/gas codes, health and safety, accessibility, and wastewater-discharge rules. A few areas matter more:

• Water and sewer / utilities. Local water rates and, in drought-prone regions, water-use restrictions directly hit the industry's largest cost line. This is the regulatory exposure that actually moves laundromat economics.
• Wastewater. The EPA (Environmental Protection Agency) withdrew a proposed national industrial-laundry pretreatment standard, leaving local wastewater authorities to set appropriate discharge limits — so this is a local, site-by-site issue.[28]
• Accessibility. Under the Americans with Disabilities Act (ADA), Title III, federal regulations specifically name laundromats and dry cleaners as "public accommodations," so stores must meet accessibility requirements.[27]
• Worker safety. For attended stores and WDF/route operations, Occupational Safety and Health Administration (OSHA) rules cover laundry-machinery guarding, hazardous chemicals, fire prevention, lockout/tagout, and worker training.[26]

Drycleaning chemicals (PCE / "perc"). The larger regulatory change is the federal phase-out of perchloroethylene (PCE, or "perc") — the traditional drycleaning solvent — finalized by the EPA in December 2024 under the Toxic Substances Control Act (TSCA). As of mid-2026 the EPA's key drycleaning dates are:[24]

• PCE use in newly acquired drycleaning machines prohibited after June 16, 2025;
• PCE use in third-generation machines prohibited after December 20, 2027;
• PCE use in all drycleaning and related spot-cleaning operations prohibited after December 19, 2034.

The EPA has said it proposed extending certain workplace-protection compliance dates in 2026 and began reconsidering parts of the rule in 2025, so anyone underwriting a drycleaning asset should verify the current compliance position.[24] Note that under the separate PCE air-emissions standard (NESHAP — National Emission Standards for Hazardous Air Pollutants), coin-operated drycleaning machines are exempt, though not necessarily from other environmental requirements.[25] This all mainly affects the staffed dry cleaners in adjacent code 812320, not self-service laundromats — but it is central to the "drycleaner" half of this industry's name and to any operator offering drycleaning. Legacy perc soil-and-groundwater contamination is a real environmental-liability tail for drycleaning sites (several states run drycleaner remediation funds).

Attended stores are also modestly exposed to minimum-wage increases, and card-payment operators to payment-surcharge and disclosure rules.

8. Competitive dynamics and consolidation

• Storefronts stay fragmented. The self-service tier remains a mom-and-pop business — tens of thousands of single-store owners. Competition is intensely local: customers care about location, parking, cleanliness, machine availability, price, security, hours, and reliability. A national brand helps, but a strong site can compete without one. There is no dominant national laundromat brand the way there is in fast food.[6]
• Route/multifamily is consolidated. Two private-equity-backed nationals — CSC ServiceWorks (largest, ~1M+ machines, ~40% of multifamily) and WASH — anchor the tier and compete hard for contracts with big apartment managers, with regional operators filling the gaps.[16][17]
• The equipment layer is concentrating. Alliance Laundry (Speed Queen) holds roughly 40% of North American commercial-laundry equipment, with employee-owned Dexter the main rival; Alliance's October 2025 IPO put a public price on the sector's most important supplier.[10][20] In distribution, EVI Industries is rolling up regional equipment distributors into a national platform.[11]
• Franchising is arriving. Branded models are bringing standardization and financing to a historically unbranded business: WaveMax (semi-absentee laundromats), Tide Cleaners (Procter & Gamble-backed), ZIPS Dry Cleaners, and franchisors like Clean Brands (Martinizing/Lapels).[15][19][22]
• Where scale actually pays. The strongest scale economics accrue to equipment makers, laundry-room platforms, payment/monitoring systems, and PUD routes — not to a nationwide chain of storefronts. Local real estate, long leases, site-specific demand, and modest store sizes make national storefront roll-ups harder than the fragmented market first suggests.
• The consolidation thesis (forward-looking). An aging owner base, a fragmented storefront population, and stable, financeable cash flows still make this fertile ground for search funds, family offices, and small private-equity roll-ups assembling multi-store portfolios — a slow-moving but real story.[21]

9. Risks

• Utility-cost inflation. Water, sewer, and gas are the biggest variable cost; rising rates or drought restrictions compress margins directly. This is the industry's number-one operating risk.[8]
• Capital intensity and equipment cost. High buildout and re-equipment costs, plus rising machine prices, lengthen paybacks; buyers dependent on SBA and equipment financing are exposed to interest rates.[9][21]
• Lease risk. Most operators lease their space; an unfavorable renewal, a rent spike, or non-renewal can impair or destroy store value.[21]
• Secular erosion of the base (forward-looking). New multifamily buildings are increasingly built with in-unit washers and dryers, and rising homeownership removes customers — both shrink the pool of renters who need a laundromat or a shared machine room. This is the main long-term substitution risk.[9]
• Operational hazards. Cash-handling, theft, vandalism, machine downtime, and property damage (fire, flood, mold) in unattended, cash-heavy stores.
• Labor. Rising wages and labor shortages in attended stores and WDF operations.
• Technology-transition and cyber. Converting coin fleets to card/app raises revenue but requires capital and carries execution risk; digital payment adds outage, cybersecurity, and customer-data exposure.
• Drycleaning's structural decline. Work-from-home and casual dress have permanently cut demand for suit-and-blouse drycleaning; adjacent code 812320 has seen revenue and store counts fall, with roughly one in six dry cleaners reported closed or bankrupt since 2020.[30] Operators offering drycleaning also face the PCE phase-out and contamination liabilities (§7).
• Private-deal risk. Overstated seller revenue or understated expenses, and the common error of confusing supplier growth (equipment makers, platforms) with growth in 812310 storefront revenue.

10. How to invest and the outlook

Public-market routes. Recognize the limitation up front: you cannot buy a listed laundromat operator. The public proxies are one layer removed — really bets on equipment demand, consumables, brands, and industry health, not on store-level cash flow:

• Alliance Laundry (NYSE: ALH) — the closest large proxy; the dominant equipment maker (Speed Queen), public since October 2025. Its results reflect global equipment sales, financing, and commercial end markets, not just U.S. laundromats.[10]
• EVI Industries (NYSE American: EVI) — a small-cap distributor/roll-up leveraged to industry capex and consolidation.[11]
• Ecolab (NYSE: ECL) and Procter & Gamble (NYSE: PG) — diversified giants with small, indirect laundry exposure (chemicals; Tide detergent and the Tide Cleaners brand).[12][15]

For public names, focus on segment exposure to vended/commercial laundry, equipment-replacement cycles, recurring parts/service/consumables revenue, pricing power, debt and free-cash-flow conversion, and capital/acquisition discipline — and read price-to-earnings (P/E) and enterprise-value-to-EBITDA (EV/EBITDA) multiples against the company's actual business mix, not against "laundromats."

Private-market routes (where this industry mostly lives).

• Buy or build a single store — SBA-financed owner-operator or semi-absentee; the classic entry point.[21]
• Buy a franchise — WaveMax, Tide Cleaners, or ZIPS for brand, systems, and financing. A franchise is not passive ownership: the Federal Trade Commission (FTC) requires a Franchise Disclosure Document (FDD) with 23 categories of information, delivered at least 14 days before you sign or pay. Royalties are brand-specific — Tide's franchise materials, for example, quote a 6.5% royalty on net sales, which is not an industry benchmark.[22][23]
• Buy the real estate plus the business — own the box and collect both the operating cash flow and the property appreciation.[21]
• Assemble a portfolio — a search-fund or small-PE roll-up of multiple stores, or acquire a route/multifamily operator for contracted, infrastructure-like cash flows.[16][17]
• Supply the industry — provide equipment, financing, maintenance, or payment/monitoring technology, where much of the durable scale economics sit.

Outlook (forward-looking judgment). Expect this to remain what it has long been: a stable, cash-generative, low-growth, income-style industry rather than a growth play. The federal establishment count has been roughly flat-to-slightly-declining, and the near-term picture is a tug-of-war:

• Tailwinds: a persistently high renter share, card/app modernization lifting price and throughput, growth in wash-dry-fold and delivery, larger machines, and a consolidation premium as fragmented owners sell.
• Headwinds: utility-cost inflation, the slow erosion of the customer base as new apartments add in-unit laundry, and high capital intensity — with the drycleaning side under heavier structural and regulatory pressure.

Net: a defensive, annuity-like allocation for private investors who want cash flow and can manage real estate, utilities, and equipment — and, for public investors, an indirect bet best expressed through selective equipment, distribution, consumables, and brand names, never on the assumption that any one laundry-related company mirrors the economics of the 812310 operating market.
