15.23.010 Adoption of the California Green Building Standards Code, Part 11, Title 24 of the California Code of Regulations.
There is adopted and incorporated by reference herein as the city green building code for the purpose of improving public health, safety and general welfare by enhanced design and construction of buildings through the use of building concepts having a reduced negative impact or a positive environmental impact and encourage sustainable construction practices the 2022 California Green Building Standards Code, Part 11 of Title 24 of the California Code of Regulations, a portion of the California Building Standards Code, as defined in the California Health and Safety Code, Section 18901 et seq., excluding the appendix chapters. Except as otherwise provided by this chapter, the planning, design, operation, construction, use and occupancy of every newly constructed building or structure shall be in conformance with the 2022 California Green Building Code and any rules and regulations promulgated pursuant thereto as published by the California Building Standards Commission. (Ord. 527 § 2(B), 2022)
15.23.020 Applicability.
The requirements of this chapter shall apply at the time of building permit application for all newly constructed buildings, as defined in Title 24, Part 2, Chapter 2, Section 202 of the California Code of Regulations, as amended by SBMC 15.22.030. (Ord. 529 § 3, 2023)
15.23.030 Definitions.
For purposes of this chapter, the following definitions shall apply:
“Mixed-fuel building” means a building that is plumbed for the use of natural gas or propane as fuel for any system. Portable propane appliances for use outside of the building envelope, such as outdoor cooking and outdoor heating appliances, that are not connected to any fuel gas infrastructure are not considered as plumbed for propane.
“Newly constructed” or “new construction” shall have the meaning as defined in Title 24, Part 2, Chapter 2, Section 202 of the California Code of Regulations, as amended by SBMC 15.22.030. (Ord. 529 § 3, 2023)

Electric ready measures include panel capacity and raceways (or conductors) from the electrical panel(s) to the location of each gas outlet sufficiently sized to meet future electric power requirements at the time of construction so that wall penetrations and demolition work is avoided at or minimized when the systems and appliances are converted to electric-powered systems. The locations of specific gas appliances shall be made electric-ready as follows:
1) Combined Cooktop and Oven or Stand Alone Cooktop. Buildings plumbed for natural gas or propane equipment shall meet the requirements of the California Energy Code, Title 24, Part 6, Section 150.0(u).
2) Stand Alone Cooking Oven. Buildings plumbed for natural gas or propane equipment shall include the following components for each gas terminal or stub out:
a. A dedicated 240 volt, 20 amp or greater receptacle within three (3) feet of the appliance and accessible with no obstructions;
b. The electrical receptacle shall be labeled with the words “For Future Electric Oven” and be electrically isolated; and
c. A double pole circuit breaker in the electrical panel labeled with the words “For Future Electric Oven”.
3) Any other gas appliances and equipment shall be deemed electric ready by a licensed design professional associated with the project, who shall provide calculations and documentation that the design includes bus bar capacity, raceway or conductor capacity, and space necessary for the installation of electrical equipment that can serve the intended function of the gas equipment.
