Summary
Cupertino requires developers to prove compliance with its local CALGreen thresholds through third-party LEED or GreenPoint Rated certification, or city review for smaller projects, and to post a refundable green building deposit. Municipal Code § 16.58.250 amends CALGreen § 102.3 with these local verification steps.
102.3 Verification. Documentation of conformance for applicable green building measures shall be provided to the City of Cupertino. Verification that the project meets the applicable environmental standards occurs through either the Third Party process or City Review per the requirements in Table 101.10. ... Green Building Deposit. The green building deposit in an amount that may be set from time to time by resolution of the City Council. The applicant may provide the deposit in the form of cash or in any other form that the City finds acceptable to meet the purposes of this Section. The full amount of the deposit shall be returned upon the certification document being provided per 102.3 (A)(4). If however, the project does not meet the requirements of this Chapter, as applied to the project, then the City shall retain the full amount of the deposit ... Time Limit. Within 18 months of Final Occupancy - Provide certification document for LEED, GPR or alternate rating standard in a form accepted by the City per Table 101.10. The Building Official may grant a one-time 6-month extension.
Full Breakdown
230, new nonresidential buildings between 25,000 and 50,000 square feet must reach LEED Certified or an approved alternate standard, while those over 50,000 square feet must reach LEED Silver; new multifamily projects of more than nine homes need GreenPoint Rated at 50 points or LEED Silver. Major renovations, defined as at least 35,000 square feet with a 50 percent floor-area-ratio increase that replace or substantially alter the HVAC system plus two other building systems, trigger the same third-party thresholds. 250 requires applicants meeting those thresholds to submit a green building checklist at both the planning application and building permit stages, register the project with the applicable certification body, and post a green building deposit in an amount set by City Council resolution.
58 requirements. Applicants have 18 months after final occupancy to deliver the LEED, GreenPoint Rated, or alternate rating certification, and the Building Official may grant one 6-month extension. 260 exempts projects where full compliance is infeasible or conflicts with historic preservation, the General Plan, or the California Building Standards Code.
Violations & Fines
A project that fails to deliver the required LEED, GreenPoint Rated, or alternate-standard certification within the 18-month window, or its 6-month extension, forfeits its entire green building deposit under § 16.58.250, which the city may use only to advance Chapter 16.58's purposes. Building without the required checklist and registration also exposes the applicant to the general misdemeanor penalty in § 1.12.010.
