Abstract
“Major transit stop”—how these three words are defined determines what can be built where, throughout much of California. To address housing shortages and reduce reliance on driving, California has enacted a number of laws that streamline housing approvals and remove zoning constraints in areas near high-quality transit. Many of these laws allow for greater density, less parking, and faster permitting within half a mile of a “major transit stop,” While the law establishes a statewide framework for what counts as a “major transit stop,” it leaves substantial room for interpretation. Key elements—such as how to measure service frequency, what constitutes a bus route intersection, or how to define the geographic extent of a “stop”—are not fully specified in statute. As a result, planners, developers, and local governments apply the definition in different ways, whether due to technical limitations, differing assumptions, or local policy priorities. These interpretive differences have meaningful consequences. To better understand these impacts, the research team compared two bookend interpretations of state law: a minimal approach using the narrowest plausible interpretation and a maximal approach using the broadest plausible interpretation, counting more as qualifying transit.
