Full Breakdown

The code applies to the planning, design, operation, construction, use, and occupancy of new buildings and structures. The City is explicit that adopting CALGreen doesn't substitute for or count as meeting any third-party green building certification (e.g., LEED). A dedicated 'Fee for Mandatory Measures' is layered on top of standard plan-check and permit fees, set by City Council resolution under the Building Code Fee Schedule, specifically to confirm CALGreen compliance.

Violations & Fines

As part of Title 8, noncompliance is enforceable under the general Building Code violation provisions (§ 8-1.23): up to a $1,000 fine, up to 6 months in jail, or both, with continuing violations treated as separate daily offenses.
