Across the United States, the housing market is facing a structural problem that few politicians are willing to address honestly: the country is short roughly five million homes. That estimate has been widely cited by organizations such as National Association of Realtors, which has warned that the U.S. housing shortage now sits somewhere between 4 and 6 million housing units depending on methodology.

This shortage is not the result of a lack of builders, a lack of land, or even a lack of financing.

It is largely the result of local zoning and regulatory policies that make building new housing extraordinarily difficult in many desirable markets.

In communities across the country, local governments have created zoning frameworks that effectively block the development of housing that average Americans can afford.

And nowhere is that more obvious than in highly desirable coastal markets like Mount Pleasant, South Carolina, where the approval process for new housing projects can stretch three to four years or more.

For large developers with millions in capital, navigating this regulatory maze is frustrating but possible.

For an individual family or small builder trying to build a modest home, it is often nearly impossible.

When Zoning Makes It Illegal to Solve the Housing Crisis

The United States does not have a housing shortage because builders don’t want to build homes.

We have a housing shortage because in many places it is effectively illegal to build enough homes to meet demand.

A landmark report by the Brookings Institution found that restrictive zoning policies — including minimum lot sizes, parking requirements, height restrictions, and lengthy approval processes — are among the biggest contributors to the national housing shortage.

In practice, these policies create a system where only large luxury projects make economic sense.

Affordable housing, starter homes, duplexes, and small multi-family units often become financially or legally impossible.

The result is predictable: fewer homes get built.

And when supply doesn’t keep up with demand, prices rise.

The “I’ve Got Mine” Housing Problem

Many homeowners celebrate rising property values, and understandably so.

But there is a point where rising home prices stop being healthy and start becoming destructive to the broader economy.

Housing prices that rise significantly faster than inflation — often defined as more than 2–3% above inflation annually — begin to create economic immobility.

When homeownership becomes too expensive:

• young families cannot enter the market
• workers cannot move to better job markets
• communities age and stagnate
• future demand for housing weakens

This phenomenon has been studied extensively by the Harvard Joint Center for Housing Studies, which has warned that rising housing costs are increasingly locking younger Americans out of homeownership.

In other words, the housing market begins to consume its own future buyers.

Zoning’s Uncomfortable History

Few people realize that modern zoning laws have a controversial history.

Early zoning policies in the early 20th century were often designed to segregate communities by income and race, restricting who could live in certain neighborhoods.

Over time those policies evolved into modern zoning rules — minimum lot sizes, density restrictions, and other regulations.

While the motivations today are often framed as preserving “community character,” the practical effect can be similar: restricting who can afford to live in a community.

Even today, economists frequently describe exclusionary zoning as one of the biggest barriers to housing affordability in the United States.

Migration Is Already Solving the Problem — Slowly

When housing becomes too expensive in one place, people move.

That migration is already reshaping the American housing market.

Cities with relatively affordable housing and growing economies are seeing dramatic population increases from remote workers, retirees, and mobile professionals.

We’ve already seen this play out in several markets:

• Charleston, South Carolina experienced explosive population and housing growth between 2010 and 2020.
• Knoxville, Tennessee has recently become one of the fastest-growing housing markets in the Southeast.
• Chattanooga, Tennessee is now attracting remote workers due to infrastructure and affordability.
• Macon, Georgia is emerging as a more affordable alternative for buyers priced out of larger markets.

The pattern is remarkably predictable.

Remote workers and retirees bring income from outside the local economy.

Local wages rise.

Housing demand increases.

Property values climb.

Then eventually those markets begin repeating the same zoning mistakes.

The Real Housing Standoff

The truth about the housing crisis is uncomfortable.

If you already own a home, building more homes can reduce the rate at which your property value rises.

If you don’t own a home, building more homes is the only way you will ever be able to afford one.

That creates a political stalemate.

Existing homeowners often push local governments to restrict development in order to preserve property values and neighborhood character.

Meanwhile, younger generations are being locked out of the housing market entirely.

The result is a housing market that increasingly benefits those who already own property — while making it harder for new families to get started.

The Bottom Line

America does not lack the resources to solve its housing shortage.

We have:

• people who want homes
• builders willing to construct them
• capital ready to finance projects
• labor capable of building them

What we lack in many markets is a regulatory environment that allows enough housing to be built.

Until zoning policies begin aligning with the reality of modern housing demand, the shortage will persist.

And Americans will continue moving to the next affordable city — repeating the same cycle again and again.
