Services to Buildings and Dwellings (United States) — Industry-Group Rollup Primer

NAICS 2022 code 5617. NAICS is the North American Industry Classification System, the standard the U.S. and Canadian governments use to group businesses by activity. 5617 is an "industry group" — the four-digit level. It sits inside subsector 561 (Administrative and Support Services), which sits inside sector 56 (Administrative and Support and Waste Management and Remediation Services). Below 5617 are five "NAICS industries" (five-digit) and, under each, one "national industry" (six-digit).

1. Overview

NAICS 5617 is the part of the economy that keeps buildings and grounds running — the recurring, hands-on upkeep of property, indoors and out. It bundles five trades that look different on a truck but behave almost identically as businesses: pest control (56171), janitorial/contract cleaning (56172), landscaping (56173), carpet-and-upholstery cleaning (56174), and an "everything else" bucket of specialized building services (56179) — pools, air ducts, chimneys, gutters, and pressure washing.[1][2]

Taken together they are one of the largest, most fragmented, and most private-equity-picked-over corners of the U.S. services economy: roughly $226 billion in employer receipts, ~217,000 firms, and 2.16 million paid workers in the reference years.[1] Every one of the five is a route-based, labor-intensive, asset-light business that sells recurring service, competes locally, has almost no barrier to entry, and is being rolled up (bought and combined) by consolidators. That shared DNA is why they are grouped together.

But for an investor the differences across the five children are the whole story — they differ sharply in size, in how much you can own on the public markets, in how concentrated they already are, and in how defensive or discretionary the demand is. This primer leads with that contrast, then covers the group as a whole. For the deep, company-by-company treatment of any one trade, see its own five-digit primer (56171 / 56172 / 56173 / 56174 / 56179) and the six-digit leaf beneath it.

2. What's inside — the five children and how they differ

Unlike its own single-child children, NAICS 5617 genuinely splits into five distinct industries. Here is how they compare.

2a. Size and concentration (federal figures, employer firms)

Receipts and CR4 are from the 2022 Economic Census; employees are from 2023 County Business Patterns (CBP). "CR4" is the combined revenue share of the four largest firms.[1][3][4]

Three contrasts jump out:

• Two children are the group. Landscaping and janitorial together are 83% of receipts and 87% of employees. The other three combined are under a fifth of the group. A view of "services to buildings and dwellings" is, first, a view of mowing lawns and cleaning offices.
• Revenue rank ≠ headcount rank. Landscaping is the biggest by revenue, but janitorial is the biggest by people — it employs half the group's 2.16 million workers on a third of its revenue. That is the fingerprint of a pure labor-arbitrage business: janitorial turns roughly $67,000 of revenue per worker, versus ~$143,000 in landscaping and pest control. Cleaning is the thinnest-margin, most people-heavy trade in the group.[5][6]
• Pest control is the odd one out on concentration. Its top four firms hold 31% of revenue — four times the group average — because two large public consolidators (Orkin/Rollins and Terminix/Rentokil) have spent decades buying routes. Every other child is far more fragmented, with the "other services" bucket the most fragmented of all (CR4 just 6%).[3][7]

2b. Ownership, how to invest, and direction of travel

The through-line: public investability falls as you go down the table. Pest control is the only child you can own as a clean listed business; landscaping offers one pure-play; carpet cleaning and "other services" can only be reached indirectly, through diversified parents where the relevant work is a small slice. Everything the public market can't reach is where private capital concentrates — which is most of this $226 billion group.

2c. What sits just outside the group

Related-sounding activities counted elsewhere include lawn-and-turf design (541320 landscape architecture), agricultural/crop pest control (subsector 115), making the chemicals and equipment (e.g., 325320 pesticide manufacturing), hazmat and environmental remediation (562910), and bundled "run-the-whole-building" integrated facilities management (561210). Each child primer maps its own boundaries.[2]

---

3. Size (this level's rollup figures)

The group's own ground-truth federal figures. Receipts, firm count, and concentration are from the 2022 Economic Census; establishments, employment, and payroll are from 2023 County Business Patterns. Read the two vintages as complementary, not as a single-year financial statement.[1]

That works out to roughly $1.0 million in average revenue and about ten employees per firm — a small-business industry group top to bottom.[1] Payroll is 39% of receipts, confirming how labor-heavy the whole group is. The much lower first-quarter payroll ($18.7 B) versus full-year ($87.2 B) reflects the seasonality that landscaping (and, to a degree, pest and pool work) injects into the group — winter is the slow quarter.[1]

One of the most fragmented industry groups in the economy. The Herfindahl-Hirschman Index (HHI, a standard concentration gauge — each firm's market-share percentage squared and summed, on a scale to 10,000) is 17.2. The U.S. Department of Justice treats anything below 1,000 as "unconcentrated"; 17.2 is a tiny fraction of that.[14] Note the arithmetic of aggregation: the group HHI (17.2) is lower than pest control's alone (327) because no firm spans all five trades — pooling five industries dilutes any one company's share of the combined $226 billion.[3][7]

Undercount caveat — large, and it varies by child. These are employer figures: they count only businesses with paid staff, and they exclude nonemployers (one-person, no-payroll operators) and in-house crews classified to their employer's industry. Both exclusions are big here because small and individual ownership dominates every child:

• Landscaping alone had roughly 434,554 nonemployer businesses generating ~$15.3 billion in additional receipts in 2023 — a tail larger, by business count, than the entire employer group.[15]
• Janitorial's in-house gap is enormous: the Bureau of Labor Statistics (BLS) counts about 2.24 million janitors across the whole occupation, roughly double the ~1.1 million on contract-cleaning payrolls — the difference is cleaners employed directly by schools, hospitals, and building owners.[5]
• Carpet cleaning and the pool/duct/pressure-washing bucket are likewise dominated by solo owner-operators invisible to the employer census.

Our ground-truth file for 5617 carries no nonemployer total, so none is stated as federal fact here. Treat $226 billion / ~217,000 firms as a formal-sector floor; the true business count runs well over half a million and the true working population comfortably above 2.5 million once the self-employed are added. Broader private market-research estimates (which fold in nonemployers and adjacent activity) run higher still and are scope-dependent — use them as context, not as this group's federal figure.[15][16]

---

4. Investable universe (where value concentrates)

Value in NAICS 5617 concentrates in three tiers, and which tier you can reach depends on which child you want.

Tier 1 — the handful of public pure-plays (mostly pest, one in landscaping). The only genuinely direct public exposure in the whole group sits in two children:

• Pest control: two scaled listed operators plus a diversified commercial player — the cleanest public exposure anywhere in 5617.[7][8]
• Landscaping: a single listed pure-play maintenance operator.[10]

Tier 2 — public "proxies" and picks-and-shovels. Larger, diversified companies where a building-service trade is part of the story: a big commercial-cleaning contractor and an institutional-housekeeping specialist for janitorial; a drain-cleaning brand inside a hospice-care parent, and pool-supply distribution/retail, for the "other" bucket; landscape-supply distribution and equipment makers for landscaping; and facilities-services conglomerates (property services, aviation/facility services, uniform-and-facility-services) that touch carpet and exterior work. You buy the parent's whole strategy, not the trade.[5][10][12][13]

Tier 3 — the private majority, where most of the $226 billion actually is. Franchise systems (cleaning, carpet, pool, and property-service brands) and private-equity roll-up platforms sit atop a base of hundreds of thousands of small independents and nonemployers. Advisers track ~90-plus PE platforms in landscaping and ~20-plus in pest control alone; franchisors and consolidators dominate carpet and "other services."[7][10][11] For private investors this tier is the opportunity; for public investors it is unreachable except through the Tier-2 parents.

There is no dedicated exchange-traded fund (ETF) for building-and-dwelling services, and no single stock that captures the group. Each child primer names the full public and private roster for its trade.

5. How the money works

Despite five different tasks, the economic engine is the same across the group — and it is emphatically not a regulated-utility, real-estate-investment-trust (REIT), or mining-cost model. It is a route-density, recurring-revenue service model:

• Recurring beats one-time. Subscription-like work — quarterly pest treatments, monthly office cleaning, weekly mowing, scheduled pool service — behaves like an annuity, renews for years, and sells at a premium to episodic project work (duct cleaning, carpet jobs, snow events, redevelopment landscaping).[7][10][13]
• Route density is the master lever. Packing more stops into each technician's or crew's day within a tight geography cuts unpaid "windshield time" and lifts billable jobs per truck — which is exactly why bolting a nearby operator onto an existing route is so accretive and why consolidation is relentless.[7][10]
• Labor is the core cost and the binding constraint. Field wages dominate; payroll is ~39% of group receipts and far higher inside labor-arbitrage janitorial. Every child reports the same ceiling: not enough workers.[5][6]
• Margins vary widely, though, and that's a real difference. Per-job gross margins can look rich (carpet cleaning runs ~55-75% before overhead), but net margins at scale are thin and trade-specific: contract cleaning nets roughly 1% at the public leader; landscaping maintenance is a low-single-digit net but ~14-22% on an earnings-before-interest-taxes-depreciation-and-amortization (EBITDA) basis; pest control throws off the strongest free cash flow, which is why it commands the group's richest valuations.[5][10][12]

The shared consolidation thesis follows directly: buy small local operators at low earnings multiples, bolt them onto existing routes, professionalize pricing and back-office software, and re-rate the denser recurring-revenue book at a higher multiple. Franchisors run a lighter-capital variant — royalties (typically ~5-10% of franchisee revenue) plus fees, and sometimes proprietary-supply sales.

---

6. Demand drivers

Demand across the group tracks the installed base of buildings, grounds, and equipment that must be maintained regardless of the economic cycle — occupied square footage to clean, lawns to mow, pools and ducts and chimneys to service, pests that keep breeding. That makes the group broadly defensive, but the children sit on a spectrum:

• Most defensive / non-discretionary: pest control (a health, food-safety, and property-value necessity) and the healthcare/education/government slices of janitorial.[7][5]
• Structural tailwind — outsourcing: roughly half of all janitorial labor is still in-house, a long runway to convert; landscaping and specialized building services see the same shift from do-it-yourself and in-house to contracted service.[5]
• More cyclical / discretionary: residential carpet cleaning (easy to defer), landscaping's design-build and development work, and new pool construction — all sensitive to housing turnover, interest rates, and consumer confidence.[10][12][13]
• Cross-cutting pulls: weather and seasonality (rain grows grass, storms drive restoration and gutter/pressure-wash work), Sun Belt migration and a warming climate (expanding pest ranges, more pools and year-round service), post-COVID hygiene and indoor-air-quality awareness, and real-estate turnover (move-in/move-out cleaning and inspections).[7][12][13]

The recurring maintenance core is far more resilient than the discretionary, big-ticket, new-build edge — a distinction that matters in a downturn.

---

7. Regulation

There is no single regulator of "services to buildings and dwellings," and regulatory intensity varies more across the children than almost anything else:

• Most regulated — pest control. A licensed, chemically regulated trade: the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), administered by the U.S. Environmental Protection Agency (EPA), governs which pesticides may be used and sets applicator-certification standards, with state-by-state licensing (generally no reciprocity). Licensing is a genuine barrier to entry and a source of durability that the other trades lack.[17]
• Labor- and immigration-exposed — janitorial and landscaping. The Fair Labor Standards Act (FLSA) plus a thicket of higher state/local minimum wages set the wage floor; the Occupational Safety and Health Administration (OSHA) governs chemical, equipment, and safety standards. Janitorial carries heavy worker-classification and immigration exposure (I-9 audits, E-Verify, the franchise-model misclassification cases). Landscaping is the single largest user of the H-2B temporary non-agricultural worker visa (capped at 66,000/year against far greater demand), making labor supply a live policy risk.[5][18]
• Lightly regulated — carpet cleaning and the "other" bucket. No federal license to clean a carpet or a pool; touch points are mostly voluntary certification, local wastewater/stormwater rules for extraction and pressure-wash runoff, OSHA safety, and — for franchisors across the group — the Federal Trade Commission (FTC) Franchise Rule and its required Franchise Disclosure Document.[12][13]

The common thread: light-to-moderate business regulation, with the sharp exceptions of pesticide law (pest) and labor/immigration law (cleaning and landscaping) as the regimes that actually move the industry.

8. Consolidation

Consolidation is the defining investment story of NAICS 5617 — and the group's structure explains why. With a group CR4 of 6.4% and an HHI of 17.2, the top firms hold almost none of the market; hundreds of thousands of small operators split the rest.[1] Near-zero barriers to entry keep new local firms forming and price competition relentless. That gap — between fragmented supply and the scale advantages (route density, purchasing power, software, brand, and a valuation premium on recurring revenue) available at the top — is exactly what fuels roll-up.

Where the roll-up has traveled differs by child:

• Pest control is furthest along — two public consolidators plus ~20 PE platforms have pushed CR4 to 31%.[7]
• Landscaping is mid-wave and moving fast — 90-plus PE-backed platforms buying recurring-revenue maintenance operators and re-rating them at 8-10× EBITDA.[10][11]
• Janitorial consolidates through franchising and facilities-management bundling more than pure acquisition, held back by thin margins.[5]
• Carpet cleaning's roll-up has migrated to adjacent, higher-value restoration rather than the fragmented cleaning core.[12]
• The "other" bucket is early — PE franchisors and a "silver tsunami" of retiring owner-operators with no succession plan are feeding regional and specialty platforms.[13]

The likely end state group-wide is many regional and specialty platforms, not one national champion — the low CR4 shows how far consolidation still has to run.

---

9. Risks

The children share a common risk spine, with trade-specific accents:

• Labor cost and availability — the group-wide ceiling: wage inflation, high turnover, and immigration-enforcement exposure (acute in janitorial and landscaping).[5][18]
• Thin, execution-dependent margins — especially janitorial (~1% net at the leader), where small missteps swing profitability, and small operators everywhere.[5]
• Low switching costs and price competition — short-cancellation contracts and near-zero entry barriers keep pricing under pressure across all five.[5][10]
• Cyclicality on the discretionary edge — residential carpet cleaning, landscaping development, and new pool builds soften with housing and consumer confidence, even as the recurring core holds.[10][12][13]
• Regulatory and chemical liability — pesticide bans and misapplication claims (pest), wastewater/runoff rules (carpet, pressure washing), worker-classification litigation (janitorial franchising).[12][17]
• Roll-up execution and leverage — integration risk and debt at the more-aggressive PE consolidators.[10][11]
• Measurement risk — federal employer stats materially understate nonemployer and in-house activity, and public "proxies" blend these trades with unrelated businesses, so both the group and its individual names are hard to size cleanly.[15][16]
• Valuation risk (where it applies) — the market prices the quality public leaders, especially in pest control, richly, leaving little room for disappointment.[8]

10. How to invest & outlook

Public-market investors have a narrow, uneven menu. The cleanest direct exposure is in pest control (listed pure-plays plus a diversified commercial player); landscaping offers a single pure-play plus equipment/supply picks-and-shovels; janitorial offers one large-cap proxy and several diversified facilities/food-service names; and carpet cleaning and the pool/duct/pressure-washing bucket can only be reached indirectly, through parents where the relevant work is a minor slice. Reserve specific tickers, yields, and multiples for each child primer, and confirm how much of any diversified name actually relates to the trade before buying it. There is no dedicated ETF for the group.

Private investors own the real opportunity. Because ~217,000 employer firms and a far larger nonemployer tail sit beneath a handful of consolidators, the group is one of the deepest small-business M&A pools in the country: buy or build a local operator (often Small Business Administration [SBA]-financeable at low cash-flow multiples), franchise into a proven system, acquire aging owner-operators on succession-driven deal flow, provide private credit to leveraged platforms, or invest alongside a PE roll-up. Commercial, contract-heavy, route-dense, recurring-revenue operators command the best valuations in every child.

Outlook. A large, defensive, cash-generative industry group growing at a steady low-to-mid-single-digit rate, where returns come from execution and consolidation rather than a rising tide. The durable tailwind is outsourcing (still roughly half of cleaning labor in-house, with landscaping and specialized services shifting the same way); the durable headwinds are labor — wage inflation, turnover, and immigration policy (H-2B and enforcement) — plus office real-estate softness for the janitorial slice and the slow carpet-to-hard-floor shift for cleaning. Expect consolidation to persist as long as the multiple gap between small operators and scaled platforms holds, producing regional and specialty champions rather than one national winner. For the full, trade-by-trade analysis — company rosters, unit economics, franchise mechanics, regulation, and diligence checklists — read the five child primers: 56171, 56172, 56173, 56174, and 56179.
