Full Breakdown
34. 010(B). The chapter replaced a prior single-section version tied to Ordinance No. 1094 (2022) when the city rewrote all of Title 15 through Ordinance No. 1139. 090 cannot issue until the completed work, including its CALGreen measures, passes inspection.
Violations & Fines
A structure built or altered without meeting the adopted CALGreen standards is treated as any other Technical Code violation: it is a misdemeanor under Section 15.04.130 (CBC Section 114.4), punishable per Chapter 1.12 of the Municipal Code, and the Building Official can withhold the certificate of occupancy required by Section 15.04.090 until the deficiency is corrected and reinspected.
