New Housing For-Sale Builders (United States) — NAICS 236117

An investor's primer. NAICS = North American Industry Classification System, the U.S. government's standard industry taxonomy.

1. Overview

New Housing For-Sale Builders are what the industry calls operative, speculative, or merchant builders: companies that acquire or control land, build new homes on their own account, and sell the finished home with the land included. This is different from a general contractor who builds a house for a landowner under a construction contract. When you tour a model home in a new subdivision and pick a lot and floor plan, you are almost always buying from a for-sale builder [1].

The defining feature is ownership of the risk: the builder controls the land, carries the home as inventory until it sells, and lives or dies by home prices, mortgage affordability, land and construction costs, sales incentives, build speed, and balance-sheet discipline. It is one of the most cyclical, capital-intensive activities in the economy — the epicenter of the 2008 crash and a strong performer in the low-rate years that followed. The industry is also unusually consolidated at the top and fragmented at the bottom: a handful of national builders now close roughly two of every five new homes in the country, while thousands of small local builders fill out the rest [14].

Two ways in. Public-market investors get one of the deepest, most liquid rosters of any construction sub-industry — more than a dozen builders trade on U.S. exchanges, from ~$32 billion giants down to regional players. Private-market investors access the industry through the many large privately held (and foreign-owned) builders, through land development and lot-banking partnerships, through private-credit lending to builders, through joint ventures, and through the build-to-rent channel where builders sell entire communities to institutional landlords.

2. What it is and how it's structured

Scope. NAICS 236117 covers establishments primarily responsible for the entire construction of new single-family or multifamily homes built on the builder's own account for sale [1]. A typical builder: (1) identifies and entitles land; (2) buys or controls finished lots; (3) builds standardized or semi-custom homes using subcontractors; (4) markets through model homes, sales offices, and digital channels; and (5) closes the sale, often providing mortgage, title, escrow, insurance, or warranty services.

What it excludes (the adjacent codes worth knowing):

• 236115 — New Single-Family Housing Construction (except For-Sale Builders): general contractors building a single-family home for others (e.g., a custom home on the buyer's own lot) [1].
• 236116 — New Multifamily Housing Construction (except For-Sale Builders): contractors building apartment/condo buildings for others [1].
• 236118 — Residential Remodelers: renovation and repair of existing homes [1].
• 237210 — Land Subdivision: developers who entitle raw land and sell finished lots (many builders buy from these).
• 531110 — Lessors of Residential Buildings: build-to-hold landlords who build to keep and rent, as opposed to building to sell [1].
• 238x specialty trade contractors (foundation, framing, roofing, plumbing, electrical): the subcontractors who perform most of the physical labor.
• Manufactured (factory-built) housing production is classified in manufacturing, not here [1].

That trade-contractor point matters for reading the numbers. A merchant builder is really an orchestrator — it assembles land, capital, designs, permits, and subcontractor crews. The hammer-swinging is largely outsourced to trades classified elsewhere. So NAICS 236117 captures the developer/seller function, not the whole labor footprint of building a house.

Ownership mix. The industry runs from publicly traded national builders (D.R. Horton, Lennar) through large private and family- or employee-owned builders (Ashton Woods, David Weekley, Perry Homes, Shea Homes), through private-equity-backed and foreign-owned U.S. subsidiaries (Japan's Sekisui House, Daiwa House, and Sumitomo Forestry all own major U.S. builders), down to thousands of small local operators run through project-level limited-liability companies. Private-equity and institutional capital also sit behind land banks, lot-option funds, and build-to-rent buyers.

3. How big it is

Core federal statistics for NAICS 236117 (authoritative for the industry's own scope):

Read these carefully — most of the labor is off the books in this code. Revenue per employee works out to roughly $2.1 million ($276.6B ÷ 132,029) — an implausibly high figure for "construction" that only makes sense because the trades who physically build the homes are subcontractors counted under other NAICS codes [2][3]. Average payroll per employee is about $119,000, far above construction norms, because the people this code does count are mostly corporate, sales, and management staff — not framers on a jobsite [2].

Undercount and unit caveats. The Economic Census counted ~18,100 firms with receipts, but County Business Patterns logged only ~12,200 establishments with paid employees [2][3]. The gap points to thousands of very small, thin-payroll, or nonemployer builders that contract out essentially everything — but note the two counts use different years and statistical units (2022 firms vs. 2023 employer establishments) and should not be differenced into a precise number, nor combined into one market-size total. The blind spot is tiny, informal, and project-specific activity, not government ownership. The federal receipts total is best read as the merchant-builder slice of new-home construction, not the full economic value of every new home built (custom homes on buyers' lots fall under 236115). The SBA $45 million figure is a qualification threshold, not an average-builder size.

Physical scale of the market (from Census/NAHB construction data, a better gauge than the receipts figure): about 1.01 million single-family homes were started in 2024 [8]; by mid-2026 the pace had cooled, with single-family starts running near a 895,000 seasonally adjusted annual rate (SAAR) and total housing starts near a 1.427 million SAAR [6]. Roughly 680,000 new single-family homes sold annually in 2024–2025, at a median price hovering near $415,000–$425,000; by spring 2026 the monthly sales pace had softened to about a 580,000 SAAR with around 10 months of supply [7]. Our federal file does not provide unit closings, average selling prices, margins, land inventories, cancellation or absorption rates, or a nonemployer count for this code — those come from the market sources cited here, not from the 236117 statistics.

4. The investable universe

This is a rare industry where the public roster is genuinely deep. Figures below are approximate, latest full fiscal year (D.R. Horton, KB Home, and Toll Brothers use October/November fiscal years); all trade on U.S. exchanges. Product mix, geography, leverage, and land strategy differ materially between them [15][16][17][19].

Smaller listed names include Smith Douglas Homes (SDHC, Southeast; 2024 IPO) and Hovnanian Enterprises (HOV). *Pending/reported ownership change: Taylor Morrison (TMHC) remained publicly traded at publication while a proposed acquisition by Berkshire Hathaway was reported to be proceeding [24]; Beazer (BZH) is the subject of a reported all-cash bid from Dream Finders (see §8) [23]. Verify current deal status before acting on either.

Recently privatized or absorbed public builders include M.D.C. Holdings (Richmond American), now inside Sekisui House U.S.; Landsea Homes, absorbed into the Apollo-backed New Home Co.; and United Homes Group [24][25].

Major private and foreign-owned platforms — how most non-listed volume is owned:

• Ashton Woods (with entry-level brand Starlight Homes) — owned by Canada's Great Gulf Group; one of the largest private builders [25].
• David Weekley Homes, Perry Homes (Texas/Florida), Shea Homes, Highland Homes, Drees Homes, Trophy Signature Homes — family- or employee-owned private builders [25].
• Brookfield Residential (owned by Brookfield) and Minto Communities USA (Florida/South Carolina) [25].
• Sekisui House U.S. (Japan) — Woodside, Holt, Hubble, Chesmar, and Richmond American brands [25].
• Daiwa House (Japan) — Stanley Martin, Trumark, and acquired regional operations [25].
• Sumitomo Forestry (Japan) — DRB Group, Bloomfield Homes, MainVue Homes [25].

Behind all of them sit land developers, lot-banking funds, and institutional build-to-rent buyers.

5. How the money works

A for-sale builder's cash cycle is front-loaded: it spends on land, entitlements, infrastructure, models, and sales staff long before it collects most proceeds at closing. Revenue is generally recognized only when the home settles, not when a buyer signs — so deposits and backlog are exposed to cancellation until close [16][18]. The economics turn on a few industry-specific levers:

Gross margin per home. Revenue is the sale price; cost of goods sold (COGS) is land + materials + labor (subcontractors) + commissions. Across large public builders, COGS breaks down roughly as land ~20%, materials ~40%, labor ~35%, and commissions/other ~5% [22]. Homebuilding gross margins ran unusually high (~25%+) coming out of the pandemic and have been compressing toward ~20% as builders discount to keep sales moving [20][21].

SG&A and operating leverage. Selling, general and administrative (SG&A) expense runs roughly 8–9% of average selling price (ASP), leaving a mid-teens operating margin at the big builders [22]. Because much overhead is fixed, profits are highly operating-leveraged to volume — margins expand fast in up-cycles and collapse in downturns.

The land model — the single biggest strategic choice. Owning years of lots outright ("land-heavy") boosts control but ties up capital and blows up if land values fall — the 2008 killer. The now-dominant "land-light" model controls lots through options with developers, paying a small deposit and only buying the finished lot when a home is ready to build. Lennar controls ~98% of its lots via options [17]; NVR pioneered the extreme version — it owns almost no land, options finished lots, and as a result earns far higher return on equity through the cycle than land-heavy peers [18]. The trade-off: options improve capital efficiency but create deposit, counterparty, and future-lot-price risk.

Spec vs. build-to-order. A spec (speculative) home is started before a buyer is found — faster to close but sold into whatever the market offers. A build-to-order (or "to-be-built") home is started after a contract, protecting margin but slower. Builders now target roughly a 50/50 mix to balance speed against margin [22].

Captive mortgage and the buydown game. Most large builders own a mortgage lender and a title company, capturing fee income and — critically today — enabling rate buydowns. Rather than cut the sticker price, a builder pays points to lower the buyer's mortgage rate (e.g., from ~6.6% to ~5.5%). It is cheaper than an equivalent price cut and keeps the buyer inside the builder's own lender. D.R. Horton reported ~73% of its closings carried a buydown [16][20]. The catch: heavy incentives eat margin — PulteGroup's incentives rose to ~8.7% of price in mid-2025, and its home-sale gross margin fell to ~26.3% in 2025 from ~28.9% in 2024 [20].

Metrics investors track: orders (demand), closings (revenue), backlog (contracted-but-not-closed, can cancel), absorption (net homes sold per active community), ASP, gross margin after incentives (the clearest read on pricing power), SG&A leverage, the owned-vs-optioned land mix, inventory turns, and normalized return on invested capital (ROIC).

6. What drives demand

The market today is rate-sensitive and affordability-constrained. Current snapshot (mid-2026): the average 30-year fixed mortgage rate was 6.55% in mid-July [9]; the NAHB/Wells Fargo Housing Market Index (HMI, a builder-confidence gauge where 50 is neutral) had fallen to 34, with 63% of builders using sales incentives [10].

• Mortgage rates and monthly affordability. New homes are financed purchases; demand tracks the monthly payment, not the sticker price. Elevated ~6.5–7% rates are the central headwind — which is exactly why builder rate-buydowns have become the industry's main sales tool [9][20].
• The lock-in effect — a builder tailwind. About 81% of outstanding mortgages carry rates below 6%, so existing owners won't sell and lose their cheap loan [13]. That starves the resale market of inventory and pushes buyers toward new homes, where a builder can buy down the rate. Builders have gained share precisely because resale supply is frozen.
• Structural shortage. The U.S. is estimated to be short ~3.7–4 million homes, the product of a decade-plus of underbuilding relative to new households [11] — the long-run demand floor under the industry.
• Affordability ceiling — the counterweight. NAHB estimates roughly 75% of U.S. households cannot afford a median-priced new home at 2025 prices and rates [12]. Builders are responding by shrinking homes and pushing entry-level product.
• Demographics and migration. Millennials and Gen Z aging into peak buying years support demand; Sun Belt migration concentrates it — the South alone hosts more than half of U.S. single-family starts [8].
• Investors and build-to-rent. Investors bought about 33% of single-family homes in Q2 2025 (mostly small landlords, not Wall Street), and builders increasingly sell whole communities into the build-to-rent channel — demand for homes built to sell is distinct from homes built to hold [32].

Editorial read: demand is not absent; it is being rationed by affordability. A meaningful drop in mortgage rates would likely lift orders before it lifts closings and margins; a weaker labor market or renewed rate increases would pressure both volume and pricing.

7. Regulation

Homebuilding is regulated almost entirely at the state and local level, which is itself the defining constraint on supply. HUD identifies zoning, land-use controls, building/energy codes, permitting, impact fees, environmental rules, and infrastructure requirements as the major housing-production variables [31].

• Zoning and land use. Local minimum-lot-size, density, and permitting rules dictate where and how much can be built. YIMBY-oriented reform — smaller lots, accessory dwelling units (ADUs), "missing middle" housing — is the main lever to expand supply, but it moves slowly.
• Entitlements, fees, and codes. Subdivision approvals, impact and utility fees, and building/energy codes add cost before a shovel moves. NAHB estimates regulation adds about $131,734 (26.4%) to the price of an average new single-family home — an industry-sponsored estimate, not a federal measure, but it illustrates the magnitude [28]. In the highest-fee jurisdictions, impact and development fees alone can reach the low six figures per home [27].
• Environmental permitting. The EPA's National Pollutant Discharge Elimination System (NPDES) generally requires construction-stormwater coverage for land disturbance of one acre or more (including smaller phases of a larger common plan) [29]. Traffic, wetlands, and stormwater reviews add time and cost.
• Affiliated-business rules. Because most large builders own captive mortgage/title/settlement arms, the CFPB's rules under the Real Estate Settlement Procedures Act (RESPA, Regulation X) govern referrals and affiliated-business disclosures and limit steering [30].
• Trade policy — a live 2025–2026 issue. Tariffs on imported lumber, cabinets, and other materials rose sharply; NAHB estimated recent tariff actions added roughly $10,900 per home [26], and Brookings put the total hit to residential-structure investment near $30 billion [27].
• Immigration and labor. The trades depend heavily on immigrant labor; tighter enforcement tightened an already-short construction workforce and pushed up labor cost [27].
• Federal housing finance. Fannie Mae, Freddie Mac, FHA, and VA loan programs set the terms most new-home buyers rely on — federal policy here shapes demand even though the building itself is locally regulated.

8. Competitive dynamics and consolidation

The structure is a barbell. Nationally the industry looks unconcentrated — a Herfindahl-Hirschman Index (HHI, a standard concentration measure) of just 248.9, well under the 1,500 "unconcentrated" line, across ~18,100 firms; the top-4 firms hold ~24.6% of revenue, the top 8 about 34.1%, and the top 50 about 60.9% [4]. That fragmentation reflects local land and entitlement markets, regional buyer preferences and codes, subcontractor networks, and the persistence of family-owned builders.

But two forces cut the other way. First, share is rising fast at the top: the ten largest builders captured a record 44.7% of new single-family closings in 2024 (easing to ~43.6% in 2025), the highest since tracking began in 1989 [14]. Second, local markets are highly concentrated — in 11 of the 50 largest metros the top-ten builders' share exceeds 90% [14]. Homebuilding is a local game where scale, land position, and subcontractor relationships compound. Large builders spread purchasing, technology, advertising, mortgage operations, and overhead across more communities, and can deploy incentives and standardized plans more aggressively in slow periods.

Consolidation is accelerating on several tracks:

• Foreign strategic buyers have rolled up U.S. builders: Sekisui House absorbed M.D.C. Holdings / Richmond American; Daiwa House built a platform around Stanley Martin/Trumark; Sumitomo Forestry controls DRB Group and others [25].
• Private equity has built national platforms: Apollo-backed New Home Co. acquired Landsea Homes [25].
• Public-market M&A is live but should be verified before acting: Berkshire Hathaway was reported to be acquiring Taylor Morrison [24]; and Dream Finders Homes (DFH) launched a repeatedly raised all-cash bid for Beazer Homes (BZH) — reaching about $32/share — which Beazer's board rejected as below its ~$41.83 book value per share; a completed deal would create roughly the seventh-largest U.S. builder [23].

Editorial read: consolidation improves scale and access to capital but won't eliminate local competition. The winners are likely those that gain share through land discipline, affordability, and operational consistency — not national size alone.

9. Risks

• Interest-rate and cycle risk. The dominant risk. Higher-for-longer rates crush affordability and volume; homebuilding is among the most cyclical industries in the economy, and job losses sharply lift cancellations.
• Margin compression from incentives. The buydown/discount arms race is already pulling gross margins from ~28% toward ~20% and could go lower if demand softens further [20][21].
• Land and inventory risk. Land-heavy builders can be trapped holding lots bought at cycle peaks (the 2008 wipeout); land impairments follow falling values. Too many completed or spec homes tie up cash and invite price cuts. Land-light options mitigate this but hand some upside — and counterparty/deposit risk — to developers.
• Construction-cost and policy shocks. Tariffs (~$10,900/home), lumber and materials volatility, and immigration-driven labor shortages raise costs the builder can't always pass through [26][27].
• Affordability ceiling. With ~75% of households priced out of a median new home, the industry may be near a demand wall until prices, rates, or incomes adjust [12].
• Regulatory/entitlement and geographic risk. Local approval delays and fees strand capital and lengthen the cash cycle; weather, wildfire, flood, hurricane, water scarcity, and rising property-insurance costs concentrate regional exposure.
• Quality and warranty risk. Construction defects can produce warranty claims, litigation, insurance cost, and reputational damage [16].
• Concentration and private-market opacity. In many metros a few builders dominate, so downturn price wars hit everyone's margins at once. Private deals may carry limited disclosure, project concentration, valuation uncertainty, leverage, capital-call risk, and complex sponsor fees; acquisitions can change brands, leverage, land strategy, and transparency.

10. How to invest, and the outlook

Public-market routes.

• Direct equities across the risk spectrum: the mega-caps (DHI, LEN, PHM) for scale and liquidity; NVR for its capital-light, high-return model; TOL for luxury exposure; mid-caps (MTH, TMHC, KBH, TPH, MHO, CCS, LGIH, GRBK) for higher growth/beta; and special-situation names like BZH and TMHC tied to pending deals.
• ETFs (exchange-traded funds): homebuilder funds bundle the theme in one ticket, but are not pure builder exposure — the SPDR S&P Homebuilders ETF (XHB) mixes in building-products, home-improvement retail, and furnishings, and the iShares U.S. Home Construction ETF (ITB) spans residential construction and related industries [33].
• Adjacent picks: building-products suppliers (e.g., Builders FirstSource, UFP Industries) and real estate investment trusts (REITs) that own the land builders option from.
• What to watch on the tape: builders are valued heavily on price-to-book and normalized earnings, not just trailing price-to-earnings — a single-year P/E misleads because earnings are cyclical, and book value anchors downside (why Beazer's board points to it). Track order growth, cancellation rates, incentive load (% of price), gross-margin trajectory, SG&A leverage, and lot count / land-option coverage.

Private-market routes. Equity or preferred equity in (or joint ventures with) large privately held builders; lot-banking and land-development funds that finance the option pipeline builders increasingly rely on; construction and land loans, mezzanine, and structured private credit to regional builders; platform acquisitions and regional roll-ups; and build-to-rent vehicles that buy finished communities as rental portfolios. Underwriting should focus on entitled lots, realistic absorption, construction timelines, buyer affordability, debt maturities, completion guarantees, sponsor economics, cancellation rights, and the exit plan.

Near-term outlook (forward-looking). The setup is a tug-of-war. Pulling up: a structural shortage of ~3.7–4 million homes, the resale lock-in that funnels buyers to new construction, and demographic demand [11][13]. Pulling down: an affordability ceiling with three-quarters of households priced out, margins compressing under incentive spending, and cost pressure from tariffs and labor [12][20][26]. Current readings — a 6.55% mortgage rate, an HMI of 34, and incentives at nearly two-thirds of builders — describe a low-volume, margin-pressured stretch [9][10]. The base case across the sector is that this resolves in builders' favor whenever mortgage rates ease meaningfully, at which point the frozen resale market and pent-up household formation could release quickly. Expect the biggest builders to keep taking share, land-light models to keep winning on returns, and consolidation — foreign, PE, and public — to continue. Returns will hinge on affordability, rates, local supply, and capital discipline, favoring operators that control land without over-owning it, preserve liquidity, and serve attainable price points.
