Editor's note— Ord. No. 989, § 5, adopted Oct. 28, 2025, repealed former Ch. 15.16, §§ 15.16.010 and 15.16.020, and enacted a new Ch. 15.16 as set out herein. The former Ch. 15.16 pertained to similar subject matter, and derived from Ord. No. 971, § 5, adopted Nov. 22, 2022.

The 2025 Edition of the California Building Standards Code, known as the California Code of Regulations, Title 24, Part 3, incorporating the "National Electrical Code," 2023 Edition, published by the National Fire Protection Association, one copy of which has been filed for use and examination by the public in the office of the building official, is adopted by reference, subject to the following additions and amendments to certain sections thereof which shall read and provide as set forth in this chapter.

Section 230.79 is amended to add a new paragraph (E), to read as follows:

Sections 230.79 Rating of Service Disconnecting Means.

(E) Modifications to Service Disconnecting Means in Existing One- or Two-Family Dwelling or Townhomes.

For existing one or two family dwellings and townhomes, the service disconnecting means may require upgrades when any of the following requirements are exceeded:

1. When any other permit is applied for and the existing main service enclosure was manufactured by Federal Pacific or Zinsco, including such panels that have been rebranded.

2. When any other permit is applied for and the enclosure contains disconnecting mean on the load side of the service disconnect manufactured by Federal Pacific or Zinsco, including such panels that have been rebranded.

3. When five (5) or more circuits are modified.

4. When any secondary power source is added.

5. When an addition increases the existing gross floor area by 50% or more.

6. When a remodel, alteration or repair to an existing building includes demolition, removal or repair of more than 50% of the structure (including walls, columns, beams or girders, floor or ceiling joists and coverings, roof rafters, roof diaphragms, foundations or similar components). For the purpose of applying this section, the following criteria shall be considered in the 50% threshold evaluation:

a. The removal or demolition of more than 50% of the exterior or interior load bearing walls.

b. Removal of the roof structure or ceiling thereby permitting installation of new circuits.

Note: The rating requirements of the bus bar and enclosure for the service disconnecting means do not require the main service entrance conductors to be upgraded as long as the main service disconnect is rated to match the rating and sizing of the existing main service entrance conductors.
