The 90-day house

The top 10 US homebuilders now close approximately half of all new single-family homes sold nationally, up from ~25% in the early 2000s. Post-2008 consolidation wiped out most regional builders and shifted origination toward the public-builder oligopoly. Buyers in new-construction submarkets increasingly have ~2-3 realistic builder options rather than the 10+ that existed pre-recession.

D.R. Horton is the largest US homebuilder by volume, delivering approximately 82,000 homes in FY2024. Lennar (~75K/yr) is second. Together the two companies build roughly one of every five new single-family homes sold in the US. Each operates a nationwide footprint with standardized floor plans, standardized supply chains, and standardized subcontractor networks; local adaptation is minimal by policy.

Public homebuilders target 90-120 calendar days from slab pour to close-of-escrow on standard plans. Custom and regional builders run 6-9 months for comparable square footage. The compressed schedule is the biggest single driver of the quality complaints in the next section: framing inspections get missed, concrete cures under load, interior finishes go on over un-dried subfloors. The speed is not a bug; it is the production model.

Most large builders now use 'land-light' option contracts rather than owning land outright. The structure reduces balance-sheet risk but tightens delivery schedules: a builder who doesn't close on land until it can simultaneously close on a buyer has strong financial pressure to complete the home on the originally planned timeline regardless of conditions (weather, material delays, inspection backlog). The business model is optimized for volume and IRR, not structural longevity.

Public rating aggregates: D.R. Horton, Lennar, and Pulte all average between 1.3 and 1.8 stars out of 5 across Trustpilot, Consumer Affairs, and Pissed Consumer. Self-selection caveat applies (unhappy customers review more than happy ones), but the consistency across three platforms and three builders is evidence. Comparable ratings 15-20 years ago were 3-4 stars. The direction of the drop tracks the post-2008 consolidation.

Hunterbrook 2024 investigation documented extensive construction defects across 60+ homeowners in 16 states who purchased from D.R. Horton or Lennar. Categories included structural (improperly compacted soil, framing failures), water-intrusion (no weep holes, missing flashing), electrical (undersized panels), and code-violation cases where homes were flagged as unsafe by third-party inspectors. Buyers described having to "fight tooth and nail" to get repairs.

Production-builder standard specs in 2025 use OSB (oriented strand board) for sheathing and subfloor, LVL (laminated veneer lumber) for structural members, vinyl siding over foam sheathing, engineered wood for trim, and hollow-core interior doors. Individually, each substitution is code-legal and has defensible engineering rationale; cumulatively, the same 2,400 sqft home built in 1995 with plywood, dimensional lumber, real-wood trim, and solid-core doors has a 30-50 year maintenance curve while the 2025 version has a 15-25 year curve.

Court records: construction-defect lawsuits against D.R. Horton and Lennar have risen exponentially in specific jurisdictions (South Carolina, Florida, Texas). A Lowcountry-area attorney reports hundreds of cases per year against major builders. Most settle with NDAs, which limits public visibility. The rising litigation volume is a lagging indicator: plaintiffs typically wait 1-3 years past close-of-escrow for latent defects (water intrusion, foundation settlement) to surface.

Lennar's 2024 Homebuyers' Warranty Guide states the company has the 'sole right to determine the repairs or replacements necessary' based on 'Workmanship Standards' it defines. Similar language appears in D.R. Horton and Pulte contracts. The legal effect is that a buyer's right to remediation is at the builder's discretion, with no independent standard; disputes over what constitutes a 'defect' versus a 'tolerable tolerance' fall to the builder's definition first.

Most major-builder purchase contracts include mandatory-arbitration clauses that waive the buyer's right to sue in court and waive class-action participation. Arbitration outcomes favor the repeat-player party (the builder) by a meaningful margin in empirical studies. The Federal Arbitration Act (as interpreted since AT&T v. Concepcion, 2011) makes these clauses enforceable even for large dollar-value consumer purchases.

Standard production-builder warranty structure: 1 year for workmanship and material defects (cosmetic, finish, minor systems), 2 years for mechanical systems (plumbing, HVAC, electrical), 10 years for structural. The 1-year cosmetic window covers the period during which most quickly-built flaws surface (settlement cracks, poor paint adhesion, flooring gaps); buyers who miss the deadline inherit the repair cost. Many buyers report being "stalled" through the 1-year window by non-responsive warranty-service queues.

Defect-case settlements with major builders typically include nondisclosure agreements barring the buyer from publicly discussing the defect or the settlement amount. The practice compounds information asymmetry: future buyers cannot see the rate or severity of past problems in a builder's history the way they could see, for example, a vehicle recall history. NDAs are not illegal but function as systemic information suppression in an already-concentrated market.

NAHB / John Burns: approximately 25% of new single-family home starts in specific Sun Belt metros (Atlanta, Phoenix, Dallas, Orlando, Tampa) are now built-to-rent — constructed specifically for institutional landlord purchase, not for owner-occupier sale. National average is 10-15% and rising. The shift converts what would historically have been first-time-buyer inventory into long-term rental product before the house exists. See the housing page's institutional-ownership section.

Invitation Homes Q3 2025 investor disclosures: 81% of the company's new single-family acquisitions (426 of 526 homes) came directly from third-party homebuilders via BTR pipeline deals, with another 1,002 homes in the pipeline. The builders receive guaranteed bulk sale; Invitation Homes receives new inventory without retail competition. Neither party is optimizing for owner-occupier affordability.

Virtually all new subdivision developments impose mandatory HOA membership. During the sell-out period (typically 3-7 years) the builder controls the HOA board, sets the budget, writes the reserve studies, and often under-funds long-term reserves so monthly HOA fees appear attractive to buyers. Post-sell-out, residents inherit the underfunded reserves and must either raise dues sharply or special-assess the deferred maintenance. It is a predictable asymmetric information transfer from buyer to builder.

Rexera / industry tracking: average US HOA monthly fees grew roughly 6-8% per year 2020-2024, outpacing CPI inflation in every year except 2022. The average single-family HOA fee is now ~$250/month; condo HOAs average ~$400. Builder-era reserve underfunding is a significant driver of the compounding increases. The fee is functionally a non-optional tax on the home that rises faster than property-tax assessments in most states.
