To promote socially equitable and engaging communities by enabling residents from a wide range of economic levels, household sizes, and age groups to live in a community.
Meet the requirements of one or more of the following options.
Option 1. Diversity of housing types (1–3 points)Include a sufficient variety of housing sizes and types in the project such that the total variety of planned and existing housing within the project achieves a Simpson Diversity Index score greater than 0.5, using the housing categories below. Projects of less than 125 acres (50.5 hectares) may calculate the Simpson Diversity Index for the area within ¼ mile (400 meters) of the project’s geographic center. The Simpson Diversity Index calculates the probability that any two randomly selected dwelling units in a project will be of a different type. Score = 1- ∑ (n/N)2 Where n = the total number of dwelling units in a single category, and N = the total number of dwelling units in all categories.
Table 1. Points for housing diversityHousing categories are defined by the dwelling unit’s net floor area, exclusive of any garage, as listed in Table 2.
Table 2. Housing categoriesFor the purposes of this credit, townhouse and live-work units may have individual ground-level entrances or be within a multiunit or mixed-use building. Double counting is prohibited; each dwelling may be classified in only one category. The number of stories in a building is inclusive of the ground floor regardless of its use.
Option 2. Affordable Housing (1–3 points)Include a proportion of new rental and/or for-sale dwelling units priced for households earning less than the area median income (AMI). Rental units must be maintained at affordable levels for a minimum of 15 years. Existing dwelling units are exempt from requirement calculations. Meet any combination of thresholds in Table 3, up to a maximum of 3 points.
Table 3. Points for affordable housing
Option 3. Housing types and affordable housing (1 point)A project may earn an additional point by earning at least 2 points in Option 1 and at least 2 points in Option 2 (at least one of which must be for providing housing at or below 100% AMI).
