It's Not One Problem

The housing shortage conversation in America is broken because everyone is arguing about one thing.

Urbanists blame zoning. Economists blame capital markets. Builders blame labor shortages. Politicians blame developers. Developers blame regulators. Everyone has identified a real constraint. Nobody is looking at how those constraints interact.

After thirty years of building housing in California, I can tell you that housing shortages don't come from a single policy failure. They come from systems failure. Zoning, capital, construction productivity, and development delivery all have to work simultaneously for housing to get built at scale. When any one of those systems constrains, production slows. When several constrain at the same time, production collapses. And it can stay collapsed for decades.

The United States is currently millions of units short of meeting housing demand. That deficit didn't happen overnight. It accumulated over years of interacting constraints that nobody addressed as a system. Fixing it requires understanding how the pieces fit together, not arguing about which piece matters most.

Housing Supply Is a Production System

The standard economics story says rising prices should trigger more construction. Demand goes up, prices go up, developers build more, supply responds. Clean and simple.

It doesn't work that way. In most high-demand markets, construction activity remains constrained even as prices climb. San Francisco. Los Angeles. New York. Boston. Portland. Prices have been elevated for years and supply hasn't responded at anything close to the pace needed.

This happens because housing production isn't governed by price signals alone. It's governed by a system of interconnected constraints. Each one has to be navigable for a project to move from concept to occupancy.

Zoning and land-use regulation determine what can be built and where. Capital availability determines whether it gets financed. Construction productivity determines whether it can be built at a cost that makes economic sense. Development delivery systems determine how efficiently the project moves through the regulatory and construction process. And development timelines determine how long capital remains at risk before the project produces income.

Block any one of those systems and the project stalls. Block two or three simultaneously and the economics don't work regardless of how strong demand is.

Zoning Is the First Gate

Land-use regulation is the most powerful structural force constraining housing supply. I've written about this in detail in Zoning and Land Use: The Systemic Gatekeeper of Scalable Housing.

In most American cities, large portions of urban land are zoned exclusively for single-family housing. Density restrictions, minimum lot sizes, parking requirements, and height limits collectively prevent the kind of multifamily production that would actually move the needle on supply.

The research on this is extensive and unambiguous. Restrictive zoning reduces housing supply and contributes directly to higher housing costs. This isn't controversial among economists or housing researchers. It's controversial among homeowners and local governments, which is why it persists.

For developers, zoning determines the opportunity set. You can't build what the code doesn't allow. And in most markets, the code doesn't allow nearly enough.

Evolve Development Group addresses these constraints directly in Top Challenges in Real Estate Entitlements and through our approach to development from concept to completion.

Capital Doesn't Match the Need

Housing production requires patient capital deployed across long timelines. Land acquisition, predevelopment, entitlements, construction, and stabilization can take five to ten years. During that window, the capital is illiquid and at risk.

The problem is that most available capital is structured for shorter-duration, lower-risk investments. Institutional investors favor stabilized assets with predictable income streams. Development capital, especially for housing at scale, requires longer horizons and higher risk tolerance.

When capital markets tighten, housing production is one of the first casualties. Not because demand disappears, but because the capital required to finance new construction becomes scarce or expensive. Projects that penciled at lower rates stop penciling at higher ones. Deals that were moving forward stall. And the supply deficit gets worse.

I explore this mismatch in Misaligned Capital Flows: The Financial Bottleneck to Housing Production. And the broader capital allocation framework that governs these decisions is examined in Capital Discipline in Real Estate Development.

Evolve Development Group has written about the capital challenges specific to housing in Affordable Housing Development Financing and Fixing the Housing Crisis Requires Fixing the System.

At Durata Advisory, we work with development sponsors to design capital frameworks that can sustain housing production through market cycles rather than collapsing at the first rate increase. The feasibility models vs. construction reality gap is where most housing deals die.

You Can't Build What You Can't Build

Even when zoning allows it and capital is available, housing production is constrained by the physical capacity of the construction industry.

Construction labor productivity has declined significantly since 1970 while productivity in almost every other sector has doubled. I examine the structural reasons for this in Why Construction Labor Productivity Has Declined Since 1970 and the broader implications in Construction Productivity: Unlocking the Physical Ability to Build at Scale.

Labor shortages are chronic. Skilled trade workers are aging out faster than new workers are entering the industry. Fragmented project delivery systems create inefficiency. Technology adoption has been slower in construction than in almost any other major industry.

The result: even in markets where regulatory and capital conditions are favorable, the physical capacity to build housing at scale is limited. You can zone for density and finance the deals, but if you can't get the buildings out of the ground, supply doesn't respond.

This is why industrialized construction, prefabrication, and mass timber are important conversations. Not for sustainability reasons, though those matter. For productivity reasons. The only way to meaningfully increase housing production is to change how we build, not just what we're allowed to build and how we finance it.

Evolve examines construction productivity at the platform level in Why Construction Productivity Matters.

Development Timelines Amplify Everything

Every constraint in the housing production system is amplified by development timelines.

Entitlement delays don't just push construction back. They extend the capital exposure window, increase financing costs, and often trigger design revisions as market conditions shift during the approval process. A two-year entitlement delay on a housing project can add millions in carry costs and change the financial viability of the entire deal.

These timeline risks are explored in Long-Duration Real Estate Capital Durability. And Durata Advisory examines how entitlement sequencing risk specifically undermines housing production.

The compound effect is significant. A project facing restrictive zoning, expensive capital, and slow construction productivity simultaneously experiences a timeline that makes the economics nearly impossible. Each constraint adds time. Each additional month adds cost. And cost accumulates faster than most pro formas model.

Systems Failure Requires Systems Solutions

Solving the housing shortage requires coordinated reform across multiple systems simultaneously. Zoning reform alone isn't sufficient if construction productivity can't scale to meet the new capacity. Capital availability alone isn't sufficient if regulatory processes take years to navigate. Construction innovation alone isn't sufficient if land-use restrictions prevent the product types that would benefit most.

The most effective approach I've seen treats housing production as an integrated system and addresses constraints at every level: regulatory reform to expand what can be built, capital structures designed for the timelines housing actually requires, construction systems that can deliver at scale, and development organizations capable of coordinating all three.

That's how I think about the work across all three platforms. Evolve Development Group addresses execution and construction delivery. Durata Advisory addresses capital structure and risk. And TysonDirksen.com documents the research and frameworks that connect them.

The housing crisis isn't going to be solved by any one of those things alone. It's going to be solved by getting them all working together.

Frequently Asked Questions

What causes housing shortages? Housing shortages arise from interacting constraints across zoning, capital markets, construction productivity, and development delivery systems. When multiple systems constrain simultaneously, housing production falls far short of demand. No single factor explains the shortage. The explanation is systemic.

Why doesn't housing supply increase when prices rise? Because housing production is governed by systems that don't respond automatically to price signals. Zoning must allow it. Capital must finance it. Construction labor must be available. Regulatory approvals must be navigable within timelines the capital structure can support. When any of these systems constrains, supply doesn't respond regardless of price.

How do zoning laws affect housing supply? Zoning determines what can be built and where. Restrictive zoning, including single-family exclusivity, density limits, parking requirements, and height restrictions, directly reduces the number and type of housing units that can be produced. In most American cities, zoning is the most binding constraint on housing supply.

Can increasing construction alone solve housing shortages? No. Construction productivity is one constraint among several. Even if construction capacity expanded significantly, housing production would remain limited by zoning restrictions, capital availability, and regulatory timelines. Solving the shortage requires coordinated reform across all major systems simultaneously.

What does a systems approach to housing look like? It looks like simultaneous work on zoning reform to expand developable capacity, capital structures designed for the timelines housing requires, construction innovation to increase productivity, and development organizations capable of coordinating regulatory, financial, and physical delivery systems at scale.
