Ask a home buyer in the Bay Area, a renter in Seattle, and a builder in rural Georgia what’s driving up housing costs, and you’ll get three different answers pointing at the same problem from three different angles. Zoning. Labor. Expensive materials. The American housing shortage in recent years wasn’t caused by just one thing. Instead, multiple problems came together and became much worse simultaneously.
The scale of the problem is significant, with different organizations all quantifying shortfalls well into millions of homes. A recent report from the White House put the shortfall at more than 10 million single-family homes in its 2026 Economic Report of the President, reasoning that homebuilding never returned to its pre-2008 pace. Zillow’s estimate lands closer to 4.5 million. Realtor.com puts the cumulative supply gap at 4.03 million as of 2025. The National Low Income Housing Coalition, measuring a narrower question — homes affordable to the lowest-income renters — counts a 7.2 million unit gap in that segment alone.
The difference in estimates exists because “shortage” isn’t just one number, it’s several overlapping questions. Are there enough homes for people who want to move today? Enough for the 18% of adults 25-34 who now live with parents, up from roughly 10% historically, many of whom would form new households if housing were cheaper? Enough at prices low-income renters can actually afford? Depending on which question is being asked, the honest answer ranges from “a genuine multimillion-unit deficit” to “a supply gap that’s real but modest in scale.” However, what’s clear is that construction has not kept pace with population growth and household formation for the better part of two decades, and prices have moved as a result.
The Rulebook Problem
The most-cited single culprit among housing economists is not the price of materials or labor— it’s paperwork. A June 2026 study from the National Association of Home Builders found that regulation at the federal, state, and local level now adds an astounding $131,734 to the price of a new single-family home, or 26.4% of the average sale price of roughly $499,500. That’s a 40% jump from the same study’s findings five years earlier, and more than double what NAHB measured back in 2011. Of that total, roughly $85,000 comes from rules applied during actual construction such as building codes, permit and inspection fees, worker-safety mandates. Another $47,000 stems from regulations during land development itself, including impact fees and utility hookup charges. NAHB’s survey found that 94% of developers say regulation routinely causes project delays, and 88% report design standards well beyond what they’d otherwise build to.
A large share of that burden traces back to zoning, much of it decades old. In many American cities, roughly three-quarters of residentially zoned land is reserved exclusively for detached single-family homes, according to research compiled on the subject — a legacy of mid-20th-century planning that effectively outlaws duplexes, townhomes, or small apartment buildings on that land regardless of demand. The Cato Institute has argued, using regression analysis across metro areas, that zoning and land-use controls are the dominant explanation for why some cities have affordable housing and others don’t, more so than construction costs or land scarcity themselves. Not every economist agrees that regulation is the primary driver rather than a contributing one, and some research argues that even well-intentioned rules like inclusionary zoning mandates can raise costs on market-rate units without meaningfully expanding the affordable supply. But the takeaway in most recent research is that local rules determine, to an unusual degree, whether a given city can absorb population growth by building or whether it simply gets more expensive instead.
That dynamic is now visibly shifting. Montana’s 2023 reforms nicknamed the legalized accessory dwelling units and duplexes on single-family lots statewide and later loosened parking mandates and height limits downtown. Dallas rewrote a zoning code that hadn’t been comprehensively updated in nearly 40 years, cutting parking requirements and easing rules on small multifamily buildings. More than a dozen states have taken up similar legislation in the past two years. The reforms point to a new trend: the fastest way to add supply is not new subsidy programs but the removal of rules that make building illegal or prohibitively slow in the first place.
Nobody to Build It
Even where a project clears every zoning and permitting hurdle, someone still has to pour the concrete and frame the walls. However, the construction industry is currently short on people to do that. The Associated Builders and Contractors estimated the industry needed roughly 349,000 net new workers in 2026 just to keep up with existing demand, a figure it projects will grow through 2028. Nearly 40% of skilled construction workers are now over 45, and in the electrical trades, close to one in five workers is over 55; apprenticeship pipelines take five to seven years to produce a fully trained replacement, which is not fast enough to offset retirements.
Immigrant workers made up 26.3% of the entire construction workforce in 2024, a record high, and around one-third of construction trades specifically. That reliance is far higher in the trades that build homes: immigrants comprise 57% of drywall and ceiling tile installers, 56% of plasterers and stucco masons, 53% of roofers, 53% of painters, and 51% of carpet, floor and tile installers, while 35% of carpenters and 43% of construction laborers are foreign-born. The dependence is geographically concentrated too — California’s construction workforce is 42.1% immigrant, followed by Florida (40.6%), Texas (39%), Nevada (38.6%), and New York (37.1%), with more than half of the nation’s roughly 3 million immigrant construction workers living in the four most-populated states.
The Price of the Parts
Layered on top of labor and land-use costs is the price of the materials themselves. Combined antidumping, countervailing, and Section 232 tariffs pushed the effective duty rate on Canadian softwood lumber to roughly 45% through 2026, even as Canada supplies about 85% of U.S. softwood lumber imports. Framing lumber prices climbed into the high $500s per thousand board feet in early 2026 as a result, and tariffs on steel, aluminum, and copper — all pulled higher separately by data-center and electric-vehicle demand — have added further pressure on non-wood components.
Financing adds a final layer. Mortgage rates have hovered in the low-6% range through much of 2026, and construction loan rates for builders have followed a similar path — high relative to the previous decade, if no longer near their 2022-2023 peaks. Because roughly two-thirds of home construction is carried out by smaller, private builders reliant on bank credit for land, materials, and labor, the cost of that credit shapes how many projects get greenlit in the first place, independent of buyer demand. NAHB’s own 2026 outlook projected only modest single-family starts growth — about 1% for the year — citing rate levels, tariff-driven cost pressure, and softer labor market conditions together, rather than any one factor in isolation.
Conclusion
Every one of these forces — restrictive zoning, procedural delay, a shrinking skilled workforce, tariff-driven material costs, and financing costs — pushes in the same direction: fewer homes built, at higher cost, more slowly. None of them alone explain a shortfall estimated anywhere from 2 million to 10 million-plus homes; together, compounding on top of each other project by project, they account for a construction pipeline that has struggled to outpace population growth for close to two decades. Reform efforts are already underway, including state zoning preemption, permitting overhauls, and apprenticeship investment. States like Montana and Texas suggest incremental progress is possible. Whether that progress can outpace the rate at which new households form, and new obstacles emerge, is the question the next several years of housing data will answer.
