Are Permit Fees Higher for Subpanel Installations Compared to Main Panel Upgrades?

By /

No, permit fees for subpanel installations are generally not higher than those for main panel upgrades. In fact, a subpanel installation typically requires a simpler permit package compared to a full panel upgrade or a whole-home rewire.

Several factors influence how these fees are calculated in California:

  • Project Scope: Local jurisdictions often determine permit costs based on the complexity and declared value of the work. Larger projects, such as a 200 amp service upgrade, often reflect higher fees because they require more extensive plan reviews and multiple inspections (such as both rough-in and final inspections).
  • Jurisdictional Variation: Fees are set by individual building departments. For example, permit costs in Los Angeles can range from $250 to $600, while in Marina del Rey, they typically range from $150 to $350.
  • Bundled Quotes: Most licensed electrical contractors will include these variable permit fees directly in your upfront project quote, ensuring that the cost of compliance is accounted for regardless of whether you are installing a subpanel or upgrading your primary service.
