Project teams must identify the Typology that aligns with their project to determine which Imperatives apply. Some Typologies require fewer than twenty Imperatives because the conditions are either not applicable or may compromise other critical needs. However, teams are encouraged to integrate the optional Imperatives into their projects wherever possible. Refer to the Summary Matrix in the Living Building Challenge Standard to view the list of Imperatives that are mandatory for each project type.


This typology is for any project that does not form the substantial portion of a complete building reconstruction. Sample projects include single-floor tenant improvements, residential kitchen remodels or historic rehabilitations of a portion of a building.


Infrastructure + Landscape

This typology is for any project that does not include a physical structure as part of its primary program, although open-air ‘park-like’ structures, restrooms, amphitheatres and the like do fall into this category. Projects may be as diverse as roads, bridges, plazas, sports facilities or trails.



This typology is for any project that encompasses the construction of a roofed and walled structure created for permanent use – either new or existing.



The Living Community Challenge provides a framework for any project that contains multiple buildings in a continuous campus, neighborhood, district or village. Sample projects include university, college or corporate campuses; residential streets; business or industrial districts; or small villages and towns.
