“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,” defined in California Public Resources Code § 21064.3 as “an existing rail or bus rapid transit station, a ferry terminal served by either a bus or rail transit service,” or “the intersection of two or more major bus routes with a frequency of service interval of 20 minutes or less during the morning and afternoon peak commute periods.” In some cases, planned future transit stops included in long-range regional transportation plans may also qualify.
