Summary
Lake County builds green-building compliance into every covered project by adopting the 2022 California Green Building Code wholesale as its own. New construction in the unincorporated county must meet its statewide mandatory measures, and the county has added its own light-pollution-reduction amendment on top of the base code.
4G.1 That certain Building Code known and designated as the 2022 California Green Building Code, is hereby adopted, and enacted as the Green Building Code of the County of Lake and is made a part of the chapter by reference with same force and effect as if fully set forth herein.
Full Breakdown
Sec. 1 of the Lake County Code adopts 'the 2022 California Green Building Code' and enacts it 'as the Green Building Code of the County of Lake,' made part of Chapter 5 by reference with the same force and effect as if fully set forth in the chapter, alongside the county's parallel adoptions of the 2022 California Building, Residential, Electrical, Plumbing, Mechanical, Fire and Existing Building Codes at Secs. 5-4A through 5-4N. The county did not stop at a bare adoption: Sec. 2-B. Like the county's other adopted construction codes, compliance is enforced by the Building and Safety Division of the Community Development Department as part of the building permit and plan-check process, and the Chief Building Official can require corrections before signing off on a project.
Violations & Fines
A green building code violation is treated the same as any other Chapter 5 violation: under Sec. 5-14, the Chief Building Official can issue a Notice of Noncompliance or Notice of Violation with 30 days to correct, and Sec. 5-14.7 makes a violation of Chapter 5 or any code it adopts by reference an infraction with a fine up to $100, or a misdemeanor with a fine up to $500 and up to six months in County Jail, with each day of continued violation a separate offense.
