Is it illegal to build walkable neighborhoods?

In most US cities the compact, mixed-use pattern that makes a neighborhood walkable cannot be built new. Single-use zoning separates homes from shops, minimum lot sizes spread destinations apart, parking minimums add asphalt, and setbacks break the street wall. A 2019 New York Times review found detached single-family houses were the only legal option on about 75% of residential land in Los Angeles and 94% in San Jose.

What zoning rules make neighborhoods less walkable?

Four common ones, together: single-use zoning (which bans shops near homes), minimum lot sizes (which spread buildings apart), parking minimums (which wrap destinations in parking), and setback and frontage rules (which push buildings back from the street). Each reduces walkability; combined, they make the traditional walkable pattern illegal to build.

Does reforming zoning make a neighborhood walkable?

Not by itself. Zoning reform removes the ban on the walkable pattern, but the building still has to happen over years, and scarcity is only one of several correlated drivers of the premium alongside proximity to jobs and transit. A walkability score measures walkable access and is best used to compare addresses, not as an appraisal.

Walkable neighborhoods cost more because they are scarce

Why do walkable neighborhoods cost more? They are scarce. Only about 11% of US households live in one, and in most American cities the compact, mixed-use pattern that makes them walkable is now illegal to build. A SafeStreets analysis of zoning, scarcity, and the walkability premium.
