Summary
Kirkland's Zoning Code requires qualifying residential, commercial and mixed-use developments to certify to a recognized green building program under KZC 115.62: ILFI Living Building Challenge, Built Green 4-Star, or LEED Platinum, among the listed options. The standard applies where a zone's density or bonus provisions call for it, not to every single-family remodel.
2. Requirements. a. To be considered a high performing building, a development shall be certified to meet the current versions of one or more of the following programs: International Living Future Institute’s (ILFI) Living Building Challenge™, Living Community Challenge™, Petal Recognition (energy, water and materials petals at a minimum), or Zero Energy™ (ZE) and Core programs; Built Green’s 4-Star™ program; the U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design™ (LEED) Platinum program.

Full Breakdown
62 establishes the City's High Performing Building Standards (HPBS) for developments in residential, commercial and mixed-use zones, aimed at cutting building energy use and decarbonizing new construction. S. Green Building Council's LEED Platinum program. The Planning Official may approve an alternative certification if it is judged equal or superior to those listed. Proof of registration in a qualifying program must be submitted before the development permit application, and at permit submittal the project must show it will meet performance standards: reaching or exceeding the zone's maximum allowed density (including any density bonus); an embodied carbon assessment with defined reduction targets; at least 20 percent of required parking as EV-ready and at least 10 percent with a working charger installed; electrical outlets at all bicycle storage areas; a deconstruction and material diversion plan; a 20 percent reduction in water use below state code; and all-electric buildings, except that gas commercial cooking appliances are allowed if wired for future electric replacement.
The HPBS requirement is triggered by dozens of individual zone chapters across the Zoning Code, including commercial, mixed-use and station area plan districts, where it is written as a condition of the applicable density and dimensions table rather than as a blanket citywide mandate on every structure.
Violations & Fines
A development that fails to certify under KZC 115.62 where the applicable zone requires it cannot obtain its development permit, since proof of program registration is a submittal prerequisite; the Planning and Building Department may reject or condition the permit application, and completed work that deviates from the certified plan is enforceable as a zoning code violation under Chapter 1.12 KMC.
