Most Sacramento homeowners pay between $2,500 and $10,000 for a panel upgrade, depending on the type of work. Adding a sub panel starts around $2,500, while a full 200-amp main service change runs higher, especially when it involves the utility connection, a panel relocation, or going from overhead to underground. The only way to know your number is a free, upfront estimate.
What affects the cost of a panel upgrade?
A panel upgrade isn't one fixed price because no two homes are wired the same way. Here are the factors that move your estimate up or down.
Service size and type
Moving from a 100-amp panel to a 200-amp panel is the most common upgrade in the Greater Sacramento Area, and 200-amp service is today's standard for a modern home. A like-for-like panel replacement at the same amperage is usually less involved than a full service change.
Panel location and accessibility
A panel mounted in an open garage wall is straightforward. A panel buried behind finished walls, tucked into a tight side yard, or in need of relocation adds labor.
Condition of the existing wiring
Older Sacramento homes, especially in established neighborhoods, sometimes have grounding that no longer meets current code, aging feeders, or corrosion at the meter. Bringing these up to code protects your home and is part of doing the job right.
Utility and permit coordination
A service change means coordinating the disconnect and reconnect, pulling a permit, and passing inspection. Permit fees in the area typically add a modest amount to the project, and they exist to confirm the work is safe.
Typical Price Ranges
Here's a realistic breakdown for the Greater Sacramento Area:
- Adding a sub panel: around $2,500
- 100-amp to 200-amp main service change: roughly $5,000 to $8,000
- Full service change with utility coordination, panel relocation, or overhead to underground: $8,000 to $10,000 or more
- Permit and inspection: usually a small added line item
These are honest planning ranges. Your actual price depends on your home, which is why we always provide a free, upfront estimate before any work begins.
How do you know if you need a panel upgrade?
You don't have to wait for a failure. Watch for:
- Breakers that trip often
- Lights that flicker when large appliances start
- A fuse box or an old, undersized panel
- Plans to add an EV charger, hot tub, heat pump, or major addition
- Warm spots, buzzing, or scorch marks at the panel (call for service right away)
If you see warning signs, it's worth a look. A panel that can't keep up is both an inconvenience and a safety concern.
Why is a panel upgrade worth it?
A correctly sized panel gives your home headroom for modern electrical loads, supports future upgrades like an EV charger or electric appliances, and reduces nuisance breaker trips. As a family-owned, owner-operator electrical specialist, we size your panel for how you actually live, not just to clear the minimum.
