The San Francisco Difference: Upgrading your electrical panel in San Francisco is a unique process involving complex coordination with PG&E, strict adherence to California’s Title 24 codes, and often navigating the challenges of older Victorian homes. This guide explains the entire journey, from initial assessment to final approval.
San Francisco’s unique blend of historic architecture and progressive electrification goals creates a distinct set of challenges for homeowners planning an electrical panel upgrade. Whether you’re driving an EV, adding an ADU, or simply need more capacity for modern appliances, understanding the local landscape—from PG&E’s requirements to navigating a Victorian home’s quirks—is crucial.
Many older San Francisco homes still operate on 60-100 amp services with outdated wiring like knob-and-tube [citation:1]. This is not only insufficient for modern life but can also lead to your home insurance being denied or canceled [citation:1]. Upgrading to a 200-amp service is often the first step toward a safer, more functional, and insurable home.
The reasons to upgrade an electrical panel in San Francisco mirror those in other cities but are often amplified by the age of the housing stock and the city’s ambitious climate goals. Here are the most common triggers:
The scope and complexity of a panel upgrade in San Francisco depend on several variables. Understanding these will help you budget and plan effectively.
The primary driver. Upgrading from 100A to 200A is the most common project. For very large homes or those with extensive electrification, a 400A upgrade (often dual 200A panels) might be necessary [citation:3].
This is a major cost differentiator in SF. An overhead service upgrade is generally more straightforward. However, an underground service upgrade can be significantly more involved if it requires trenching through sidewalks or streets, requiring permits and complex coordination with PG&E [citation:3].
Sometimes, your new panel must be moved to a new location to meet current codes regarding working clearances or placement (e.g., from a bathroom or closet). Relocating a panel adds labor and material costs for extending service conductors and rewiring circuits [citation:1][citation:3].
Older homes with knob-and-tube or deteriorating wiring may need significant rewiring when the panel is replaced to ensure the entire system is safe. This is especially common in Victorian and Edwardian homes [citation:1][citation:4].
An electrical permit from the San Francisco Department of Building Inspection (DBI) is mandatory. Permit fees are based on project scope and are an unavoidable part of the process [citation:1].
In San Francisco and the rest of Northern California, any change to your main electrical service requires approval and coordination with PG&E. This is often the most time-consuming part of the project. Your electrical contractor will manage this process, but it’s important to understand the steps [citation:3][citation:7][citation:10].
Before you can even apply to PG&E, you must first secure your electrical permit from the San Francisco DBI. PG&E requires this as proof that your project is approved by the local authority [citation:3][citation:7].
Your electrician will submit a service upgrade application to PG&E through their online portal, “Your Projects,” along with the necessary documentation, including the city permit and detailed plans [citation:3][citation:7].
PG&E assigns a “Job Owner” to your project. They will review your application to ensure the local grid can handle your increased load. In some cases, they may require an engineering deposit and conduct a field visit. This review can take several weeks or even months, especially for complex projects [citation:7][citation:10].
Once the design is approved, PG&E provides a contract and an invoice for any costs related to their work, such as upgrading the service drop or installing a new meter. Customers are responsible for paying this before any utility work is scheduled [citation:7].
After the contract is signed, PG&E schedules the necessary work. On the installation day, a PG&E crew will temporarily disconnect power to your home. Your electrician then performs the panel replacement. After your electrician’s work passes the city inspection, PG&E returns to reconnect the service and install the new meter [citation:3][citation:10].
Be prepared for potential delays. Homeowners and developers have cited “pervasive” problems with PG&E, including communication issues and long wait times for approvals. While PG&E reports reducing its backlog, it’s wise to factor significant lead time into your project plan, especially for ADU-related upgrades [citation:5].

Our team handles the entire process, from the initial load calculation and engineering to managing your DBI permit and all communication with PG&E. We understand the unique challenges of SF homes and ensure your upgrade is safe, code-compliant, and as smooth as possible.
The timeline for a San Francisco electrical panel upgrade is highly variable, but you can generally expect the process to take anywhere from 2 to 6 months or more from initial consultation to final approval.
Pro Tip: Start early. If you’re planning a kitchen remodel, ADU, or EV purchase, begin the electrical planning and application process well in advance.
California’s Title 24, Part 6 energy code has specific requirements that affect panel upgrades. While a like-for-like panel replacement may not trigger all of them, upgrading to a higher capacity (e.g., 100A to 200A) often does.

San Francisco’s iconic Victorian homes present unique challenges that can add complexity and cost to a panel upgrade.

For San Francisco homeowners looking to maximize energy efficiency and control, a smart electrical panel is an excellent option. While a standard 200A panel serves as a simple distribution point, a smart panel, like the SPAN Panel, offers advanced features [citation:3]:
The equipment cost for a smart panel is higher than a standard panel, but the features can be invaluable for homes with solar, batteries, and EVs [citation:3]. For more on this technology, read our guide on smart panel installation.
An electrical panel upgrade in San Francisco is more than just swapping a box on the wall. It’s a complex process that intertwines local permitting, strict utility coordination with PG&E, and California’s forward-thinking energy codes. By understanding the key factors—from your home’s age and service type to the intricate PG&E approval steps—you can navigate this essential home improvement with confidence. Partnering with an experienced local electrician who knows the intricacies of San Francisco and PG&E is the single best way to ensure a successful and timely project.
