How LEED Certifications Fared in the Multifamily Sector in 2023

An in-depth analysis by project size, location and award category.

Multifamily owners and operators continued to invest in sustainability upgrades, and many made a strong effort to align to current LEED standards. Thanks to data from the U.S. Green Building Council, we’ve filtered the results by state, number of projects, square footage and type of LEED certification.

Some 197 projects across the U.S. received a certain level of LEED certification throughout 2023, amounting to nearly 34.4 million square feet, excluding confidential data. This includes multifamily projects that used both LEED Commercial and LEED Residential certification types and were recertified with LEED Commercial. The top 10 states for LEED certification for multifamily projects—including the District of Columbia—accounted for 29.4 million square feet across 165 projects.

California remained the uncontested leader with 45 multifamily projects with LEED certifications, which totaled 5.7 million square feet combined. The state also had the highest number of LEED Platinum certifications (26), 10 LEED Gold, and eight LEED Silver, while the basic LEED certification went to one project. Among the projects awarded LEED Platinum in California were graduate and family housing communities from UCI and UC Davis.
