Transit-Oriented Development

One of the most effective ways to reduce transportation sector emissions is to increase access to and ridership of public transit networks, and shifting development patterns to build more housing near existing or planned transit service, also known as transit-oriented development (TOD), can support these goals. There are many types of tools that states have at their disposal to encourage transit-oriented development. This policy captures a broad range of policy levers that help increase housing near transit networks, including upzoning requirements, incorporation of TOD in local planning requirements, funding opportunities, and permitting incentives.

The details of these policies vary significantly state to state – there are no one-size-fits-all development patterns that will work in every type of community. There are, however, common mechanisms available for states. States can designate, or require localities to designate, different kinds of development districts based on their population size and proximity to transit services, and set or incentivize increased density requirements within these transit districts. They can also require master planning processes at the county or local level to prioritize or encourage planned development within a community built within access to transit services. States can require zoning codes to support denser housing, also known as “upzoning,” within an accessible distance to transit, or offer other permitting incentives to qualifying projects. They can also offer specific funding opportunities or technical assistance for communities that amend their zoning codes to encourage denser development near transit.

Model States

California

State law overrides restrictive local zoning to permit mid-rise and high-density multi-family housing, between 7-9 stories, within a half-mile of major rail stations and rapid bus corridors in urban transit counties. There are two development tiers, based on transit type and frequency, and applies to any qualifying site zoned for residential, mixed-use, or commercial properties within a half-mile of qualifying transit, or a quarter-mile for small cities.

Colorado

A transit-oriented community must meet its housing opportunity goal, which is determined based on an aggregate zoning capacity calculation of 40 dwelling units per acre of transit-related area within the community. To accomplish its housing opportunity goal, a transit-oriented community must ensure that the zoning capacity within certain areas of the transit-oriented community meets or exceeds the transit-oriented community's housing opportunity goal.

A transit-oriented community is defined as a local government that: (1) either entirely or partially within a metropolitan planning organization, (2) has a population of 4,000 or more, and (3) contains at least 75 acres of certain transit-related area; or, if the local government is a county, contains either (a) a transit station area that is both in an unincorporated part of the county and within one-half mile of a station that serves a commuter rail or light rail service or (b) a transit corridor area that both is in an unincorporated part of the county and is fully encompassed by one or more municipalities.

The MBTA Communities law requires the 177 cities and towns that host MBTA public transportation service or abut a town served by MBTA service to designate at least one district where multi-family housing can be built, at a minimum gross density of 15 units per acre.

Oregon's Administrative Code requires certain metropolitan areas outside Portland to designate climate-friendly areas. These locations must be served or planned for "high-quality" transit. Obligated localities must be zoned so that 30% of their future housing needs can be met in climate friendly zones, wherein multi-family and attached single-family housing must be permitted.

To qualify, projects must sit within a quarter-mile radius of a regional mobility hub or a eighth-mile radius of a frequent transit stop, as defined by the Rhode Island Transit Master Plan. The Executive Office of Housing (EOH) can make individual financial awards based on scoring criteria, however, the program is currently not funded to provide financial TOD incentives. EOH encourages municipalities to apply for their current or planned TOD district to streamline the process once funding is available.
