Housing Shortage: Can Zoning Reform Fix It?

Prefer to listen instead?

• U.S. home availability dropped 32%, worsening the housing shortage.

• 75% of urban residential land is zoned for single-family homes only, limiting density.

• Minneapolis saw a 63% jump in multi-unit permits after eliminating single-family-only zoning.

• Zoning reform takes 2–5 years to yield new housing, delaying market impact.

• Without affordability mandates, new development risks skewing toward luxury housing.

The Housing Shortage: Can Zoning Reform Fix It?

Millions of Americans face higher home prices, rising rents, and shrinking supply. Affordability is getting worse. Many experts say old local zoning laws are the main cause. Zoning reform means updating land-use rules to allow more varied housing and more homes in one place. It has become a key policy tool. But can these changes really help with the affordable housing crisis? What real changes can buyers and sellers expect?

The Current Housing Crisis by the Numbers

Higher prices and slow building have caused one of the worst housing shortages in recent U.S. history. The numbers speak for themselves.

As of 2024, almost half of U.S. cities have a big lack of housing (U.S. Census Bureau, 2024). The difference between how much people earn and how much housing costs keeps growing. In most big cities, prices have gone up almost three times faster than wages. This means many first-time buyers cannot afford homes, and the rental market is under great strain.

The high costs are not just a problem for low-income renters. Middle-class people also find it harder to buy or rent good housing where they work.

What Caused the Housing Shortage?

The housing crisis now comes from problems that have built up over decades. It is not just one sudden event. Knowing why it happened helps us see what zoning reform can do, and what it cannot.

1. Underbuilding Since the Great Recession

Homebuilding dropped sharply after the 2008 recession. The population kept growing, but new home building stopped. From 2010 to 2020, the U.S. built over 3.8 million fewer homes than needed for the population. And this shortage is still getting bigger today.

2. Permitting Bottlenecks

Getting permits is slow. And rules often change from one town to the next. In many cities, getting permission to build, even on land where it is allowed, can take 12 to 24 months. These delays make things less certain and more costly for builders. They also stop new projects from starting.

3. Exclusionary and Restrictive Zoning

Zoning rules from the mid-20th century often favored single-family homes. They also stopped smaller, denser kinds of housing. This stops builders from meeting today’s housing needs. And it makes land cost more by limiting what can be built.

4. High Construction Costs

Not enough workers, tariffs, and supply chain issues from the pandemic made material and labor costs jump. Even with more demand, builders find it hard to make projects work financially. This is especially true for homes people can afford when they first buy.

5. Investor Activity in Starter Homes

More and more, big investors and hedge funds are buying single-family homes to rent out, especially in Sun Belt states. These buyers pay cash for starter homes. This has made it harder for first-time buyers to compete.

Zoning Laws: A Hidden Barrier to More Housing

Zoning rules decide what can be built and where. For many years, these rules have favored spreading out homes on big lots.

A Look at Restrictive Zoning Practices

• Single-Family Zoning: In many cities, up to 75% of land for homes is only for detached single-family houses. This greatly limits building things like duplexes or townhomes. This is true even in areas close to jobs and public transport.

• Minimum Lot Sizes: In richer suburbs, rules often say each home must be on a lot of 10,000 square feet or more. This makes housing cost more and use land less well.

• Parking Requirements: Rules often demand two or more parking spots per home. This not only adds to building costs but also uses up land that could be for housing.

• Height and Setback Restrictions: These local rules can greatly limit how many homes can be built on one site. This stops more affordable housing from being built.

These rules were often meant to keep neighborhoods looking a certain way. But they have also led to racial and economic separation. And they have made the housing crisis worse.

What Is Zoning Reform?

Zoning reform means updating or getting rid of old land-use rules. This allows for more homes, and more types of homes, to be built. By changing the laws that control building, governments can make housing fit better with today’s population and economy.

Common Zoning Reform Policies

• Upzoning: This means changing areas meant for few homes to allow more homes in one place. For example, allowing three- or four-unit buildings on lots once zoned for a single home.

• Legalizing Accessory Dwelling Units (ADUs): This allows things like backyard cottages, garage apartments, or basement homes on single-family lots.

• Reducing Minimum Lot Sizes: Smaller lots can help make homes cheaper. And they allow more homes to be built on each acre of land.

• Flexible Use Zoning: This allows homes in business or mixed-use buildings. This is especially useful in city centers where fewer people need office space.

• Form-Based Codes: This is a newer way of zoning. It focuses on how buildings look and what they do, instead of strict rules about what land can be used for.

Together, these are tools to help with the “missing middle.” This means housing types between single-family homes and big apartment buildings. It includes duplexes, townhomes, and small apartment buildings.

Recent Zoning Reform Success Stories

Some cities and states have made big zoning changes. These are starting to show good results.

California (SB 9 – 2021)

SB 9 largely ended single-family-only zoning in much of California. It let homeowners split their lots and build up to four homes. The results have been mixed because of problems with putting the law into practice. But the law has made way for more building in existing suburban areas.

Minneapolis (2018)

Minneapolis got rid of single-family zoning across the city. It also made duplexes and triplexes legal. This made it a model for the country. Since the change, the city saw a 63% rise in permits for multi-unit buildings. This shows people want to build when rules are less strict.

Oregon (HB 2001 – 2019)

Oregon’s rule says cities with over 10,000 people must allow duplexes and other mid-sized homes on almost all housing lots. The law aimed to make zoning rules the same across the state. And it gave clear instructions to builders.

Portland

Portland put its Residential Infill Project and Middle Housing Code into action. This allows up to four homes per lot in many neighborhoods. Because of this, permits in the changed zones jumped 74%. This shows that good zoning changes can lead to much more housing being built (City of Portland, 2023).

Can Zoning Reform Scale Nationwide?

The idea is good, but doing it nationwide is hard.

Challenges to Nationwide Implementation

• Local Resistance (NIMBYism): Homeowners worry about traffic, parking, or “how their neighborhood will look.” They often fight against zoning changes.

• Different Local Rules: Land-use choices in the U.S. are made by many different local groups. Without a plan for the whole country, zoning changes usually happen slowly and in different ways.

• Cost and Labor Problems: Even where zoning allows building, high land costs, rising interest rates, and not enough construction workers can stop homes from being built.

• Legal Challenges: In some places, statewide changes get challenged in court or by public votes to undo them.

To make a real difference, experts suggest federal aid. For example, linking money for roads or public transport to towns that meet housing building goals.

How Long Before Impacts Are Felt?

Zoning reform is not a quick fix. It takes time. Changing regulations is only the first step.

• Development Timeline: First, land is rezoned. Then come permits, design, getting money, and building. Most projects take 2 to 5 years before new homes are ready to buy or rent.

• Market Lag: Builders also look at market trends, if they can get money, and what buyers want before they decide to build.

Zoning reform is very important. But it will not fix things quickly. Right now, there are not enough homes. This will likely stay true for several more years.

The Affordability Question

Just because zoning allows more housing doesn’t mean that housing will be affordable.

Two Key Pitfalls:

• Land Speculation Increases Prices: In some cities, allowing more homes made land cost more. This, in turn, made it harder to build affordable housing.

• Luxury Development Dominates: Builders might focus on expensive homes if there are no rules for affordability or help with costs. This lets them make the most money.

Cities must pair zoning reform with ways to keep housing affordable. These include rules for affordable homes, tax breaks, and public-private groups working together. This helps make sure new homes meet the needs of renters and lower-income buyers (Brookings Institution, 2024).

Beyond Zoning: Other Bottlenecks to Watch

Zoning is a basic step, but it is not enough by itself. Other major problems also hold back housing construction.

• Permit Processing Delays: Permit systems that are slow or done by hand can delay projects by a year or more. This is true even if zoning allows building.

• Financing Barriers: Higher interest rates have made it harder to get building loans. This is especially true for smaller builders and projects in existing areas.

• Labor Shortage: There are 15% fewer construction workers than before 2008. This greatly limits how many homes can be built, even if other things are right.

We must make the whole process of building homes better. This includes everything from zoning to finish. Only then can we really fix today’s crisis.

What Buyers and Sellers Can Do Now

Rules will take time to change the market. But if you are dealing with real estate now, there are ways to get better results.

Buyers

• Look at suburbs or cities with fewer rules or those trying out zoning changes. More homes might appear there first.

• Work with agents who know about new homes or builder deals.

Sellers

• List your home now. There are not many homes for sale, and competition is low.

• Use our 1% Listing Fee. This can cut down on sale costs, and you still get full support.

Every market has opportunities. Being informed and supported makes all the difference.

Cities Leading the Way

These cities show how putting zoning reform with smart rules can change things:

• Minneapolis: Known for making big zoning changes early on. Saw a 63% rise in permits for small multi-unit buildings.

• Austin: Used zoning help, like allowing more homes or easier parking rules, to get more housing built near public transport.

• Portland: Got a 74% rise in permit activity in upzoned areas under its Middle Housing Code (City of Portland, 2023).

These facts show that strong rules and political will can bring real change.

How Zoning Reform May Reshape Neighborhoods

As these changes spread across the country, neighborhoods and how we think about housing will change.

• Look for more low-rise, multi-unit buildings where only single-family homes used to be.

• Lot sizes will get smaller, especially in city areas that are built up. This makes better use of the land.

• Buyers should know their local zoning maps. Properties with flexible zoning might have building or investment chances.

• ‍ More places to walk and more homes could help local businesses, especially with public transport focused building.

Zoning changes might not seem huge right away. But over time, they will greatly change how cities are built.

What Smart Housing Policy Should Include

For zoning reform to work, it needs other housing solutions along with it:

• Put upzoning together with rules that require affordable housing.

• Make permits faster by using computers and online systems. This will cut down on delays.

• Give money for roads and other public works to cities that build near public transport.

• Give tax breaks or low-interest loans for affordable homes and homes for workers.

• Give power to community land trusts and non-profits to build homes that stay affordable forever.

When part of a full plan, zoning reform can greatly improve who can get housing and fairness.

Dealing with the 2025 Market With Confidence

Even when homes are hard to find, there are ways and tools to help you do well:

• Compare real costs of selling to an investor vs. listing traditionally.

• Claim available closing cost credits and buyer rebates—every dollar helps.

Every market has opportunities. Being informed and supported makes all the difference.

Final Word: Zoning Reform Is Key, But Not a Cure-All

Zoning reform makes way for more affordable housing. But it will not fix everything right away. Putting it into action is slow. Building is costly. And public pushback can stop even the best rules.

Still, it is a basic fix. If we do not update how and where we build, the U.S. will keep having too few homes. For buyers and sellers, the main thing is to act smart now. Use any savings you have, work with good agents, and use strong online tools. Also, watch for places where changes might bring more homes next.
