Back to Baltimore-style Density? Families Want More Choice, Not 15-Minute Cities

Ideas about zoning shift like fashion. Sometimes skirts are long, sometimes short.

When suburbs grew, the style was separation. Housing here, retail there, offices elsewhere, smokestacks far away. This was the “anti-city”—a sprawl stitched by cars. Cars gave people what cities could not: escape.

Now planners dislike cars. They work hard to make driving harder. The new alternative is the “15-minute city.” In this model, work, groceries, schools, and doctors sit within a walk or bike ride. The pitch is lifestyle and sustainability: fewer cars, greener streets, tighter communities.

Sounds charming. But do most people want it?

We’ve seen this movie. In 1920, Baltimore’s 733,000 residents squeezed into 80 square miles of land —half the state’s population on less than 1% of its land area. By 1950 the city’s population peaked at 950,000. Brick rowhouses, 35–40 homes per acre crammed into lots as little as 12 foot wide. It created density planners today dream of. A shopping trip was limited to what you were willing to carry.

And yet… people left. They didn’t want the “15-minute” life. Cars gave buyers more space. They took it.

Baltimore now holds 7,100 residents per square mile, far below its peak. It also has 15,000 vacant houses and 20,000 vacant lots. That’s not a demand for density. That’s people opting out. Many Marylanders elsewhere fret about “too little affordable housing.” If density were the dream, Baltimore would be paradise. Instead, it’s empty rowhouses and weeds.

Let’s do the math. A person can cover a little over a square mile in 15 minutes. The model for the “15 Minute City” is Paris. However, the City of Light has far more to offer in terms of appeal beyond its density. Each neighborhood may have 59 bakeries and 197 food stores. Yet each is the size of a postage stamp with the selection to match.

In the U.S., the numbers are different. There’s one supermarket for every 7,500 people carrying an average of over 30,000 products. Even with higher densities, most people would still lack a supermarket within a 15-minute walking distance. Unless you count 7-Eleven as a “complete community.”

You may have five small markets within a 15-minute walking distance. However, none sells what Costco does three miles away—with variety and low cost. Call that “unsustainable” if you like. For families, it’s called “paying the bills.”

Take jobs. Experts say a good commute is under 30 minutes. With a car, scores more employers are in reach. Without, you’re stuck with what’s near home. That may work if you’re a barista in Dupont Circle. But if you’re a nurse or cybersecurity analyst whose job isn’t zoned next door, you are out of luck.

Curiously, even in Paris, the model “15-minute city,” most don’t walk to work. Only 12 percent commute in 15 minutes or less. Why? Jobs aren’t always near home. Your doctor may not be in your arrondissement. The affordable store may be miles away.

Here’s the truth. Buyers and renters have voted in the housing market. They prefer less density when they can. That’s why demand spreads outward—to suburbs, exurbs, small towns. People don’t hate cities. They like choice. Cars expand those choices.

However, planners and net-zero ideologues overlook market math. They know best. They write manifestos. Thrive Montgomery 2050, for example, promises “complete communities” with “15-minute living” as its principle. Translation: higher densities, mixed-use zoning, and fewer cars. This is social engineering wrapped as sustainability.

The irony: “15-minute living” claims to expand choice. In practice, it shrinks it.

Still, planners and net-zero ideologues push back. They insist limits make people happier. But restricting choice has never worked—whether in food lines, housing queues, or now, commuting.

The 15-minute city is a clever slogan, not a blueprint. At best, it romanticizes Paris’ density that doesn’t exist here. At worst, it cuts access to jobs, retail, and family budgets.

Baltimore proved a century ago that people, given the chance, leave density. They move outward for space and freedom. Buyers said “no thanks” then. They still say it now.

Housing is for people, not planners and net-zero ideologues. Mobility is for freedom, not fashion.
