Requirements

Option 1: Development density
Select space in a building that is located in an established, walkable community with a minimum density of 60,000 square feet per acre net (13,800 square meters per hectare net). The density calculation is based on a typical two-story downtown development and must include the area of the project being built.

OR

Option 2: Community connectivity
Select space in a building on a site that meets the following criteria:
  • Is located within 1/2-mile (800 meters) of a residential area or neighborhood with an average density of 10 units per acre net.
  • Is within 1/2-mile (800 meters) of at least 10 basic services.
  • Has pedestrian access between the building and the services.
For mixed-use projects, no more than 1 service within the project boundary may be counted as 1 of the 10 basic services, provided it is open to the public. No more than 2 of the 10 services required may be anticipated (i.e., at least 8 must be existing and operational). In addition, the anticipated services must be documented appropriately to demonstrate that they will be operational in the locations indicated within 1 year of occupation of the applicant’s project. Examples of basic services include the following:
  • Bank
  • Place of Worship
  • Convenience Grocery
  • Day Care Center
  • Cleaners
  • Fire Station
  • Beauty Salon
  • Hardware
  • Laundry
  • Library
  • Medical or Dental Office
  • Senior Care Facility
  • Park
  • Pharmacy
  • Post Office
  • Restaurant
  • School
  • Supermarket
  • Theater
  • Community Center
  • Fitness Center
  • Museum
Proximity is determined by drawing a 1/2-mile (800 meter) radius around a main building entrance on a site map and counting the services within that radius. Greenfield developments and projects that do not use existing infrastructure are not eligible. See all forum discussions about this credit »

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.

Replace the definition of "Previously developed sites" with "Previously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development."
