Rooming and Boarding Houses, Dormitories, and Workers' Camps (U.S.) — NAICS 721310

1. Overview

This industry covers the "group housing" that sits between hotels and ordinary apartments: workers' camps at remote mines and oilfields, off-campus dormitories and Greek houses, residential clubs, and old-fashioned rooming and boarding houses. What ties them together is that residents pay for a room — often with meals, housekeeping, or laundry bundled in — in a shared, managed facility that may serve as their principal home for the length of a job, a semester, or longer [1].

It is best understood as a fragmented housing-and-lodging niche made of three quite different businesses. Student housing and longer-term room rentals behave like residential real estate — steady, occupancy-driven, locally financed. Workforce accommodation — the modular "man camps" and remote lodges that house crews building mines, liquefied natural gas (LNG) plants, lithium projects, and, increasingly, remote data centers — behaves like project infrastructure: cyclical, contract-driven, and far more volatile.

Why it matters to an investor: the measured for-profit slice is small, but workforce accommodation is one genuinely investable growth story, running on long-term, contracted, take-or-pay economics that look more like industrial services than hospitality. The rest — dormitories and rooming houses — is mostly owned by universities, nonprofits, private-equity landlords, and small individual operators, and is reached through private markets rather than public stock.

Public exposure is narrow and concentrated in workforce lodging: two U.S.-listed pure-plays (Target Hospitality and Civeo), plus Canada's Black Diamond Group as a peer. There is no listed U.S. student-housing or rooming-house company left — the last public student-housing landlord was taken private in 2022. Everything else is private (tickers and figures are in Sections 4 and 10).

2. What it is and how it is structured

NAICS (North American Industry Classification System) code 721310 comprises establishments primarily engaged in operating rooming and boarding houses, off-campus dormitories, fraternity and sorority houses, residential clubs, and workers' camps — facilities that provide temporary or longer-term rooms and may add complementary services such as meals, housekeeping, and laundry [1].

In practice the code spans three very different businesses:

• Workers' camps / workforce accommodation — permanent, modular, or mobile lodges housing hundreds to thousands of workers near resource projects and large construction sites, usually with catering, transportation, security, utilities, and facilities management bundled in [22].
• Off-campus dormitories and Greek housing — privately operated student housing, fraternity and sorority houses, often leased by the bed for an academic year, sometimes under university partnerships.
• Rooming and boarding houses / SROs (single-room-occupancy buildings) — small buildings renting single rooms by the week or month with shared bath and kitchen, historically the cheapest rung on the housing ladder [23].

Ownership and operation are frequently split: a third-party manager may run a facility owned by a university, government, nonprofit, private landlord, or investment fund, so a single property can involve separate owner, operator, and manager entities.

What it excludes (adjacent NAICS codes). Traveler hotels and motels are 721110; casino hotels 721120; bed-and-breakfast inns 721191; other traveler accommodation 721199. Recreational vehicle (RV) parks and campgrounds are 721211; recreational and vacation camps (except campgrounds) are 721214. Apartments and other residential rentals where the owner is simply a landlord — including most student-housing real estate held for rent — fall under lessors of residential buildings (531110), not here. Nursing and assisted-living facilities are health care (623xxx); homeless shelters and emergency/transitional housing are community services (624221). The distinction is operational: 721310 is about operating a serviced rooming facility, not merely leasing space [1].

Ownership mix. The for-profit, employer establishments captured by federal business statistics are dominated at the top by a handful of workforce-lodging operators and a long tail of small rooming houses and Greek houses. But the largest physical stock in this category — on-campus college dormitories — is run by universities and colleges (mostly public or nonprofit) and classified under education, not here. Much SRO stock is owned by individual landlords with no employees, or by nonprofits running supportive housing. So the "industry" as an investment differs sharply from the "industry" as a slice of the housing stock.

3. How big it is

Federal statistics for the for-profit, employer part of NAICS 721310 (United States). These come from two different reference years and should not be read as a single-period snapshot.

At roughly $2.0 billion in receipts across about 1,300 firms, this is a small industry by dollar count — smaller than a single large hotel chain. Note the unusual labor profile: about 7,500 paid employees against $2 billion of receipts, because camp operators outsource much of the on-site labor (catering, cleaning) and dormitories and rooming houses are thin on staff. Payroll is only about 13% of receipts. (CR is the concentration ratio — the combined revenue share of the largest N firms; the HHI is a standard concentration gauge, discussed in Section 8.)

The undercount is large and matters here. County Business Patterns and the Economic Census cover only establishments with paid employees; they exclude the self-employed, nonemployer businesses, and most government operations [2]. That leaves out:

• On-campus university housing. Millions of students live in college- and university-owned dormitories, operated by educational institutions and classified outside this code. That is by far the biggest chunk of "dormitory" beds in America and is essentially invisible in these numbers.
• Nonemployer rooming houses. Individual landlords renting a few rooms with no payroll are counted as "nonemployers" and excluded from the establishment and payroll figures above.
• Foreign-heavy operators. The largest listed camp operator, Civeo, books most of its revenue in Canada and Australia [8], so its scale does not flow into U.S. receipts.

Read the $2 billion as the measured U.S. for-profit core, not the economic footprint of group housing, which is many times larger once campus and nonprofit beds are counted. Our data does not include national bed or room capacity, occupancy, average daily rate, same-property revenue, or operating margins for this code; those should not be inferred from receipts or employment.

4. The investable universe

Pure-play public exposure is thin and concentrated in workforce accommodation. There is no listed U.S. student-housing company and no listed rooming-house company; those are private.

Adjacent public names (not in 721310) worth knowing. The on-site catering that makes a camp livable comes from food-services giants — Aramark (NYSE: ARMK), Compass Group (LSE: CPG), and Sodexo (Euronext: SW) — which run remote-site dining but are classified under food services, not lodging. Hotel brands and hotel REITs (real estate investment trusts — companies that own income real estate and pass most profits to shareholders) offer adjacent lodging exposure but fall under traveler accommodation, not this code [1].

Major private and other owners:

• Student housing (all private). The Scion Group is now the world's largest student-housing owner at roughly 105,000 beds across ~161 communities [14]. Greystar and Landmark Properties are the largest developer-operators; Core Spaces and Campus Apartments are active off-campus and university-partnership operators [15][16][17]. The Preiss Company reports ~37,000 beds across 12 states [18]. Institutional owners include Harrison Street (~28,300 U.S. student-housing beds in its core portfolio) and Kayne Anderson (more than 81,000 beds acquired or developed since inception) [19][20]. The Michaels Organization owns and develops affordable, workforce, and student housing [21]. Blackstone (NYSE: BX) took the last public U.S. student-housing REIT, American Campus Communities, private for about $13 billion in 2022 [12][13].
• Workforce / oilfield lodging (private). Regional operators such as Permian Lodging (a 1,200-unit camp outside Midland, Texas) and T-Rex Lodging serve U.S. shale basins directly [22].
• Rooming houses / SROs. Overwhelmingly owned by individual landlords and nonprofit supportive-housing organizations; effectively no listed vehicle. Company-reported private bed counts above may mix owned, managed, and joint-venture assets and are not directly comparable with the federal NAICS counts.

5. How the money works

The core revenue equation is the same across segments — available beds or rooms × occupancy or utilization × rent or room rate, plus ancillary services — but the economics, and the metrics that matter, differ sharply by subsector.

Workforce accommodation (the investable core). Operators build or buy modular rooms, own the lodge, and charge a day rate per occupied bed that bundles the room plus catering, housekeeping, water and wastewater, power, and security. The drivers:

• Billed rooms / occupancy against owned room capacity — the closest analog to a hotel's RevPAR (revenue per available room), but contract-driven rather than nightly [8].
• Contracted vs. spot mix. The best revenue is take-or-pay — multi-year commitments where the customer pays for a block of rooms whether or not they are filled. Target's recent awards are explicit: a Lithium Nevada housing contract worth about $175 million with roughly $111 million of minimum revenue, and a data-center-community contract with about $134 million of committed minimum revenue [7]. Minimums convert a cyclical, commodity-linked business into something closer to an annuity, though they reduce occupancy risk without eliminating renewal or counterparty risk.
• Capital intensity and returns. Rooms are the asset base: capital in, depreciate, earn day-rates. Returns hinge on keeping owned rooms utilized across the resource cycle, so operators watch Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) and free cash flow and lean on long contracts to protect deployed capital. In a good year the model throws off cash (Civeo reported roughly $88.2M of Adjusted EBITDA on about $638.8M of 2025 revenue); in a downturn, empty owned lodges still carry fixed costs and depreciation, and the company can post a net loss even with contracts in hand (Civeo's 2025 net loss was about $20.1M) [8][9].
• Cost edge. For customers, a camp bed can run as little as ~$36 a night versus $200–$500 for scarce hotel rooms in a boom town — the reason clients sign up in the first place [22].

Dormitories / student housing. Rent-per-bed × occupancy, with leases that turn over each academic year. The key operating figure is the pre-lease rate — how full the building is booked before the fall term. Because these are largely held as real estate, returns are usually expressed as same-property net operating income (NOI — rental income minus operating expenses) and property yields rather than day rates. Investors also track renewal rates, bad debt, and turnover cost. (Most of this exposure lives in real-estate codes, not 721310.)

Rooming houses / SROs. Weekly or monthly room rent with very low overhead and shared facilities. Individual-operator economics turn on collections, tenant turnover, repair cost, and code compliance; when run as supportive housing, they are increasingly cross-subsidized by government or nonprofit funding.

Across all three, asset-level NOI, maintenance capital expenditure, free cash flow, leverage, and debt maturities matter more to owners than any single hotel-style metric. A broad measure such as ADR (average daily rate) or RevPAR is useful for camps but far less informative for long-term room rentals.

6. What drives demand

Demand is segment-specific and, for camps, project- and cycle-driven:

• Commodity and construction capital spending. Workforce lodging tracks client capital budgets across oil, gas, coal, iron ore, copper, and now lithium and other critical minerals, plus big builds like LNG export terminals and pipelines. When clients cut spending, occupancy falls fast: Civeo's Canadian segment revenue dropped about 40% year-over-year in early 2025 as oil-sands customers pulled back [8].
• The new driver: AI and data centers. Building remote data centers for artificial intelligence (AI) is emerging as a fresh source of camp demand. Target signed a 48-month contract expected to generate more than $750 million to house roughly 3,370 workers supporting AI-infrastructure construction, and points to a multi-billion-dollar addressable market in the theme [7].
• Government and humanitarian demand. Camp operators also house government populations — for example immigration processing and disaster response — which swings with policy, appropriations, and procurement. Target's PCC government contract (serving up to 6,000 people) was terminated in February 2025, while its Dilley immigration-processing facility was reactivated under a new five-year contract [5][6].
• College enrollment (student housing). Driven by enrollment at large public universities, on-campus bed shortages, transportation, local zoning, and international-student flows — set against a looming demographic "enrollment cliff" as smaller birth-year cohorts reach college age. National enrollment is projected through 2031, but each university market's trajectory matters more than the national total [30].
• Affordable-housing shortage (rooming houses). Persistent affordability pressure and a shrinking supply of low-rent units support demand for the cheapest shared rooms, though residents' limited ability to pay can cap rent growth and collections [29]. The loss of more than a million SRO units by 2000 is widely tied to the rise of modern homelessness [23].

Forward-looking judgment: student housing and longer-term room rentals should be more defensive; workers' camps offer higher upside when projects accelerate but far more exposure to commodity prices, construction cycles, customer cancellations, and asset underutilization.

7. Regulation

There is no single federal regulator; oversight is layered, segment-specific, and heavily local.

• Local land use. Zoning, building, fire, health, sanitation, occupancy, landlord-tenant, and business-licensing rules often determine whether a property can operate at all and how many residents it may house.
• Workers' camps. Employer-provided worker housing is governed by the temporary-labor-camp standard of the Occupational Safety and Health Administration (OSHA), 29 CFR 1910.142 (CFR = Code of Federal Regulations), which sets sanitation, water, shelter, sleeping-space, bathing, and toilet requirements and can apply to both agricultural and non-agricultural workplaces [25]. The Migrant and Seasonal Agricultural Worker Protection Act (MSPA) adds housing, transportation, disclosure, and farm-labor-contractor registration requirements for covered agricultural workers, enforced by the Department of Labor (DOL) [26]. Camps also face state labor-camp rules and environmental permits for on-site water and wastewater.
• Fair housing and accessibility. The Fair Housing Act (enforced by the Department of Housing and Urban Development, HUD) prohibits discrimination in most housing [27]; the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act can apply to student housing and housing in educational settings [28].
• Rooming houses / SROs. Shaped — and historically suppressed — by local zoning and building codes. From the 1950s onward, cities revised codes to eliminate or ban SRO units; New York banned new SRO construction in 1955 [23]. The pendulum may be swinging back: Iowa (2017), Oregon (2021), and Colorado (2024) passed laws striking down local bans on house-sharing, and a proposed federal ROOM Act aims to revive the low-cost segment [23][24].
• Government- and university-population lodging. Adds public procurement, contract, accessibility, environmental, and public-record requirements, plus heightened political and reputational scrutiny.

Regulatory classification is itself consequential: a facility treated as residential housing faces different rules from one treated as a hotel, campground, or temporary labor camp.

8. Competitive dynamics and consolidation

By federal concentration measures the industry is fragmented, not concentrated: the top four firms hold 39.3% of receipts, the top eight 49.4%, the top 20 60.4%, and the top 50 67.6%, with an HHI of just 492.8 — well below the 1,500 threshold U.S. antitrust agencies treat as "unconcentrated" [3]. The long tail of small rooming houses and Greek houses keeps national concentration low even though a few large camp operators exist. Local markets can still be tight, because zoning, land, campus proximity, utility capacity, permitting, and customer contracts create real barriers to entry.

Scale advantages accrue in purchasing (food, furnishings, modular units), staffing and compliance, access to construction and real-estate capital, the ability to serve large universities, energy companies, or government agencies, and the option to redeploy modular assets across projects. Consolidation is real at the top of each segment:

• Workforce lodging is consolidating around Target and Civeo in North America and Black Diamond (which bought Royal Camp Services in 2025) in Canada [5][8][11].
• Student housing has consolidated hard in private hands — Blackstone's ~$13 billion take-private of American Campus Communities in 2022 removed the sector from public markets, and Scion has since become the world's largest owner via acquisition, with assets recycling among Harrison Street and other institutional investors [12][14][19].

The competitive edge in workforce lodging comes from three things: owning rooms in the right basins near demand, locking in take-or-pay contracts, and bundling services (catering, utilities, logistics) that raise switching costs and margins. Rooming houses and small boarding facilities, by contrast, stay locally owned and hard to aggregate.

9. Risks

• Cyclicality. Camp demand rises and falls with client capital spending on commodities and megaprojects; a downturn empties owned rooms while fixed costs and depreciation continue [8].
• Customer and contract concentration. Revenue leans on a few large resource, university, or government clients, and contracts can be cut — Target's ~6,000-person PCC government contract was terminated in early 2025 [5][6]. Minimum-revenue agreements reduce occupancy risk but not renewal or counterparty risk [5][8].
• Occupancy / lease-up risk. New student beds or rooming-house supply can overwhelm local demand.
• Operating-cost inflation. Labor, food, utilities, insurance, repairs, and compliance costs can erode margins.
• Capital intensity and financing. Building rooms ties up capital; higher rates, refinancing needs, and falling property values pressure highly leveraged owners.
• Asset obsolescence. Modular camps may have limited resale or redeployment value once a project ends.
• Policy, social-license, and reputational risk. Immigration-lodging and labor-camp work is politically sensitive; zoning opposition, safety incidents, accessibility failures, and affordability concerns can delay projects or damage reputation.
• Demographic risk (student housing). A coming decline in college-age cohorts threatens occupancy at weaker schools.
• Secular decline and regulatory hostility (rooming houses). Zoning and codes have suppressed SRO supply for decades; any revival depends on further local and federal reform [23].
• Measurement risk for investors. Because so much of the "industry" is university- or nonprofit-owned and captured only partially by employer statistics, public-market exposure is narrow and does not track the broader group-housing story [2].

10. How to invest and the outlook

Public routes. Lead with exposure quality, not the sector label. The cleanest listed exposure is workforce accommodation: Target Hospitality (Nasdaq: TH) for a U.S.-centric, increasingly contracted book; Civeo (NYSE: CVEO) for Canadian/Australian resource lodging (with commodity and currency risk), best treated as a global comparable rather than a U.S. proxy; and Black Diamond Group (TSX: BDI) for a Canadian camp-plus-marketplace model [5][8][11]. For "picks-and-shovels" of remote living without owning the rooms, the site-catering majors — Aramark, Compass Group, Sodexo — run remote dining but are diversified food-services firms, not pure plays. Blackstone (NYSE: BX) offers only indirect student-housing exposure inside a much larger platform [12]. There is no listed pure-play U.S. student-housing or rooming-house company — and hotel-company valuation multiples should not be applied to dormitories, camps, or rooming houses.

Private routes. Student housing is now a private-markets story reached through funds and operators such as Blackstone, Scion, Greystar, Landmark, Core Spaces, Harrison Street, and Kayne Anderson, or through university public-private partnerships (P3s) [14][15][19][20]. Oilfield and project lodging can be backed via regional operators directly; the low end — SROs and supportive housing — is a direct-ownership or nonprofit/impact play. A practical underwriting checklist: demand (enrollment and bed supply, local housing shortage, or contracted project pipeline); revenue (preleasing, occupancy, rent per bed, ADR, minimum room commitments, renewals, customer credit); cost (labor, food, utilities, insurance, repairs, required capital expenditure); financing (debt maturities, rate exposure, leverage, cash-flow coverage); and exit value (zoning, alternative use, asset liquidity, customer concentration, modular redeployment).

Near-term drivers (forward-looking). The most important swing factor is the pivot of workforce lodging from commodity cycles toward infrastructure construction — data centers and AI, lithium and critical-minerals mines, and LNG — where operators are signing multi-year, minimum-revenue contracts that could smooth historically volatile earnings; Target's stated addressable market and its $750 million-plus AI-infrastructure award are the clearest signals [7]. Offsetting that, oil-sands and coal-linked demand remains soft [8], government-population contracts stay politically volatile [5], and student housing faces a demographic headwind even as institutional money keeps consolidating it. For the rooming-house segment, the key wildcard is whether zoning reform (state house-sharing laws and a possible federal ROOM Act) meaningfully revives America's cheapest housing rung [23][24]. Overall: durable underlying demand from housing affordability, university enrollment, and remote projects, but uneven growth — student housing and room-based accommodation structurally steadier, workers' camps more cyclical but with the contracted backlog as the most concrete near-term support. Public-market access stays limited; private owners, universities, nonprofits, and real-estate funds capture most of the asset-level economics. These are judgments about direction, not guarantees.
