Local Law 86 of 2005 (LL86)

Mayor Michael R. Bloomberg signed Intro 324 into law on October 3, 2005. Known as Local Law 86 of 2005 (LL86), the law was developed by the Administration in conjunction with the New York City Council.

LL86 Rules

The Rules for LL86 were published by the Office in draft form for public comment on December 1, 2006.  Following a public comment period, a public hearing, and the issuance of a Statement of Necessity in accordance with Chapter 45, Section 1043 of the New York City Charter (City Administrative Procedure Act or CAPA), the final Rules became effective on April 2, 2007.

June 21, 2009 Amendment to the LL86 Rules

The June 21, 2009 amendment to the LL86 rules took effect following the public comment period and hearing required by CAPA. This amendment redefines the selected green building rating system as the Version 3 LEED® 2009 suite of systems, the most recent version published by USGBC.

Executive Order 149 of 2011

On June 27, 2011, the Mayor issued Executive Order 149.  In addition to exercising the same powers and duties of the Mayor regarding the implementation of LL86 as those in Executive Order 97 of 2006 that it supercedes, Executive Order 149 authorizes the Director to expand the category of projects subject to the law's goals and polices, to periodically evaluate the stringency of  the law's minimum requirements, and, as warranted by developments affecting the green building industry, to make these requirements more stringent through the issuance of amendments to the LL86 Rules.
