Summary
Monterey County Code § 18.11.010 adopts the 2025 California Green Building Standards Code, Title 24 Part 11 (CALGreen), as the county's Green Building Standards Code, with local amendments layered on top: § 18.11.060 forces on-site renewable energy generation on large non-residential projects, and § 18.11.050 offers fee-rebate incentives for builders who exceed CALGreen Tier 1 or Tier 2.
That certain document entitled 2025 California Green Building Standards Code, California Code of Regulations, Title 24, Part 11, also known as CALGreen, as published by the California Building Standards Commission, is hereby adopted as the Green Building Standards Code for the County of Monterey.

Full Breakdown
11 was repealed and re-enacted by Ord. No. 5442, § 13, effective December 9, 2025. 010 adopts the 2025 California Green Building Standards Code, California Code of Regulations Title 24, Part 11, published by the California Building Standards Commission, as the Green Building Standards Code for the County of Monterey. 040 sets the compliance standards, treating CALGreen's mandatory minimum requirements as roughly equivalent to LEED basic certification and an eighteen-point GreenPoint rating, CALGreen Tier 1 as roughly equivalent to LEED Silver and a thirty-three-point GreenPoint rating, and CALGreen Tier 2 as roughly equivalent to LEED Gold and a sixty-five-point GreenPoint rating.
060 imposes a genuinely local mandate beyond the state code: all new non-residential structures greater than 25,000 square feet must provide on-site renewable energy generation covering at least 15 percent of projected energy demand, though the Compliance Official may grant an exception if the applicant demonstrates on-site generation is not appropriate for the site and shows an alternative design still achieves that 15 percent efficiency target. 050 for a Step 1 or Step 2 incentive rebate against construction permit fees, set by Board of Supervisors resolution, plus a county 'healthier home or business' award; alternative rating systems like LEED or GreenPoint Rated require documentation from a qualified professional, at the applicant's expense, before the Compliance Official will approve the incentive.
Violations & Fines
The renewable energy mandate in § 18.11.060 is a hard requirement for qualifying non-residential projects, not an option; the Compliance Official reviews and can deny the site-specific exception unless the applicant proves on-site generation is infeasible and that the substitute design still hits the 15 percent efficiency threshold. Projects seeking incentive rebates under § 18.11.050 that submit incomplete or unverified rating documentation are not entitled to the Step 1 or Step 2 rebate.
