Full Breakdown
09," pointing installers to the operative technical standards. 030, which amends the 2025 California Fire Code section by section for Monterey County under Ord. No. 5442, adopted December 9, 2025. 1, layering on signage beyond what the Building and Residential Codes already require. 1 requires a permanently affixed placard at the main service disconnect panel, red with white capital letters at least 1/2 inch high in a non-serif font, reading "SOLAR DISCONNECT INSIDE PANEL," made of weather-resistant, durable plastic with engraved letters or another approved material.
4 requires signage naming the installing contractor and an emergency phone number next to the main disconnect. 4 sets a hip-and-valley rule: modules placed on both sides of a hip or valley must sit at least one and one-half feet from it, while modules on only one side of an equal-length hip or valley may sit directly adjacent to it. These standards apply to unincorporated-area permits processed under the 2025 California Building, Residential and Fire Codes as locally amended; Monterey County's incorporated cities enforce their own separately adopted codes.
Violations & Fines
The Fire Code amendments carry no standalone fine; missing or noncompliant solar signage and layout is a Building/Fire Code deficiency that blocks final inspection sign-off and permit closeout under Section 18.09.030. An installation lacking a code-compliant "SOLAR DISCONNECT INSIDE PANEL" placard, breaker label, or the 1.5-foot hip/valley module setback will fail inspection and must be corrected before the Building Official or fire authority approves the system.
