Full Breakdown
28 of the San Marcos Municipal Code, most recently updated by Ordinance No. 010. 28 contains no separate local amendment sections beneath the adoption clause, meaning San Marcos applies CALGreen's statewide mandatory measures, covering water efficiency, storm water management, material conservation, indoor air quality, and construction waste diversion, exactly as the state edition writes them. 010, so a new residential or commercial project in San Marcos is checked against CALGreen's mandatory provisions at the same plan check and inspection stages as the rest of Title 24.
The City Council periodically re-adopts the chapter to track each new state code cycle, most recently doing so alongside the broader Title 24 update effective under Ordinance No. 2025-1575.
Violations & Fines
CALGreen compliance is checked at plan check and verified at inspection alongside the rest of the adopted Title 24 codes; a project that doesn't meet CALGreen's mandatory measures, such as required construction waste diversion or water-efficiency fixtures, won't clear plan check or final inspection until it's corrected, and the Building Official can withhold a certificate of occupancy for noncompliant work under the same enforcement authority used for Building Code violations.
