Summary

Full Breakdown
10, as promulgated by the International Code Council and the California Building Standards Commission, with a filed printed copy on record with the city clerk. Hawthorne applies the adopted standards to the planning, design, operation, construction, demolition, use and occupancy, and ongoing operations and maintenance of buildings citywide, covering four mandated areas: energy efficiency, water efficiency and conservation, material conservation and resource efficiency, and environmental quality enhancement. C. , that exceeds the applicable federal energy conservation standard for that product, so a federal appliance-efficiency ceiling overrides any stricter local reading of the state Green Code.
The chapter was last readopted, along with the rest of Title 15's building codes, under Ordinance 2239, Section 12, in 2023. Because the Green Building Standards Code is folded into Title 15, compliance is checked at plan check and final inspection alongside the Building, Plumbing, and Electrical Codes rather than through a separate green-building permit track.
Violations & Fines
Compliance is verified during the same plan-check and inspection process as the rest of Title 15: under Section 15.75.010 the director of building and safety withholds permits and certificates of occupancy when a project does not meet the adopted Green Building Standards Code. A project built or altered without meeting the adopted green-code requirements is subject to Section 1.20.010's citywide misdemeanor penalty, a fine of up to $1,000, up to six months in jail, or both, with continuing noncompliance charged as a new offense each day.
