Electrical Panel Upgrades in San Marino
San Marino's housing stock is largely post-war construction, and many of those original panels were never designed to carry the loads that come with whole-home electrification. Large south-facing roofs make the city a strong candidate for solar, but solar inverters and battery backup systems require a panel that can handle the added circuits and bidirectional flow. On top of that, HOA rules in parts of San Marino govern where equipment can be placed on the exterior of the home, which affects conduit routing and meter base positioning. A panel upgrade here is not just a box swap. It requires planning for equipment placement that meets both utility requirements and community standards. Build Bright scopes every job with those local constraints in mind so the finished installation is clean, code-compliant, and HOA-ready from day one.
The ducts are often the weak link. A high-efficiency system pushing air through leaky 1960s ducting never delivers its rating.
What that involves
- Service upgrades from 100A legacy panels to 200A or 400A modern service
- Subpanel installation for garages, ADUs, and added circuits
- Electrification-ready capacity planning for EV chargers, heat pumps, and solar interconnection
- Exterior equipment placement coordinated to meet HOA and utility requirements
- Full permit pull and utility coordination handled by our team

Electrical Panel Upgrades questions from San Marino
- How do I know if my panel needs to be upgraded?
- Common signs include breakers that trip frequently, a 100A or smaller service, a fuse-based panel, or a planned addition like an EV charger or heat pump that exceeds your current capacity. A site assessment will confirm what your panel can handle and what it cannot.
- What size panel do most San Marino homes need?
- Most post-war homes in the area are moving to 200A as a minimum. Homes adding solar, battery storage, and EV charging alongside a heat pump system often benefit from a 400A service or a 200A main with a second 200A subpanel. We size based on your actual load, not a one-size number.
- Will my HOA need to approve the work?
- Some San Marino HOAs have rules about exterior equipment placement and visible conduit. We review those requirements during the scoping visit and route the installation accordingly so you are not left managing a conflict after the work is done.
- How long does a panel upgrade take?
- A straightforward 200A service upgrade is typically a one-day job once permits are approved. Work involving a new meter base, utility coordination, or subpanel in a detached structure may take an additional day. We give you a clear timeline before work begins.
- Do you handle the permit and utility approval?
- Yes. Build Bright pulls the required permits and coordinates with the serving utility for inspection and service reconnection. You do not need to manage separate calls to the utility or the building department.
