Summary
Palm Springs adopts the 2025 California Electrical Code by reference under Municipal Code § 8.04.050, then layers on local amendments in § 8.04.055 that reach every new single-family electrical permit: a dedicated conduit for future solar, and a bigger minimum service disconnect. New one-family dwellings need a 200-amp, 3-wire service disconnect on a 225-amp bus, plus solar-ready conduit.
That certain document, a copy of which is on file with the office of the city clerk, being marked and designated as the 2025 California Electrical Code, California Code of Regulations Title 24, Part 3, including Article 89, and all appendices, tables and indices thereto except as amended herein, is hereby adopted by reference as the Palm Springs Electrical Code pursuant to Section 50022.1 et seq., of the California Government Code. ... Provisions for Future Solar PV Energy Systems. A one-inch diameter electrical conduit shall be provided for installation of future solar PV energy systems on single-family dwellings. The one-inch diameter electrical conduit shall extend from the exterior wall location adjacent to the main electrical service panel and terminate into the attic space. At each location, the conduit shall terminate at a two-gang, electric junction box. Three open spaces shall be provided at the bottom of the buss to accommodate future solar PV systems. ... 230.79(C) One-Family Dwellings. ... For a one-family dwelling, the service disconnecting means shall have a rating of not less than 200 amperes, 3-wire, with a minimum 225 amp bus.

Full Breakdown
1 et seq. 055 then modifies that adopted code with several local additions that shape what an electrical permit for new construction must include. 8(A) requiring every single-family dwelling to be roughed in for future solar: a one-inch diameter electrical conduit running from an exterior wall location next to the main service panel into the attic space, terminating at a two-gang electrical junction box, with three open spaces left at the bottom of the buss specifically to accept a future solar PV system, even if the home is not being built with solar installed.
79(C), governing one-family dwellings, sets the minimum service disconnect at not less than 200 amperes on a 3-wire service with a minimum 225-amp bus, larger than the code otherwise defaults to, with an exception for attached single-family units already equipped with a solar-ready 200-amp busbar panel. 15(B)(1)(2)(a), which requires any NM, NMC, NMS or other Chapter 3 wiring installed in an exposed attic or an unconditioned space to be rated for an ambient temperature that is considered to exceed 140 degrees Fahrenheit, reflecting how hot an unconditioned Palm Springs attic gets, well above the national default assumption most electrical plans are drawn against elsewhere.
Violations & Fines
Installing a smaller service disconnect than the 200-amp, 225-amp-bus minimum on a new one-family dwelling, skipping the required solar-ready conduit rough-in, or wiring an exposed attic without accounting for the 140-degree-plus ambient temperature rating are plan-check and inspection failures the Department of Building and Safety enforces before it will sign off on the electrical permit. Work that proceeds without a permit at all, or that departs from approved plans, is subject to the same stop-work and re-inspection process as any other unpermitted electrical work.
