Do I Need a Permit to Upgrade My Electrical Panel?
Upgrading your home’s breaker box isn’t something most people plan for—until the lights flicker, breakers keep tripping, or a new appliance pushes the system past its limit. That’s when homeowners start wondering, Do I need a permit to upgrade my electrical panel? The answer matters more than you might think.
Permits aren’t just paperwork—they protect your safety, ensure the work meets code, and keep your home’s records clear for insurance or future sales.
If you skip this step, you could face fines or even have your power shut off. So, do I need a permit to upgrade my electrical panel before calling an electrician?

What Is an Electrical Panel?
Your electrical panel—often called a breaker box—is the control center for your home’s power. Electricity enters the panel from the utility company, and from there it’s divided into individual circuits that power outlets, lights, and appliances.
Do I Need a Permit to Upgrade My Electrical Panel?
The short answer is almost always yes. Across most U.S. cities and counties, upgrading an electrical panel is considered major work.
Local building departments require a permit because the job involves the main service line, rewiring connections, and often increasing the amount of power coming into your home.
You’ll need a permit for:
- Replacing the entire panel. Swapping an old fuse box or an outdated breaker panel always needs approval.
- Upgrading service size. Moving from 100 to 200 amps—or 200 to 400 amps—means a bigger power supply. Inspectors must review this change.
- Changing the meter base. Since this connects directly to the utility line, a permit is mandatory.
These projects aren’t minor—they affect how power flows through your home and carry real safety risks.
That’s why building departments want every major panel job inspected for safe grounding, correct breaker sizing, and full compliance with the National Electrical Code (NEC).
Some small repairs—like replacing a single breaker, tightening a screw, or adding a missing label—don’t usually require a permit.
But for a full panel replacement, an amperage upgrade, or any work touching the main service line, a permit isn’t just suggested—it’s the law.
Why Panels Need to Be Upgraded
Panels don’t last forever. Many older homes still have 60‑ or 100‑amp panels that were designed decades ago, long before today’s heavy electrical demands. Modern households use more energy—charging electric cars, running HVAC systems, using high‑wattage kitchen appliances—and older panels can’t keep up.
Common reasons for an upgrade include:
- Frequent breaker trips
- Flickering or dimming lights
- Burning smells or scorch marks
- Adding major appliances
Why Permits Matter for Electrical Panel Work
The Purpose of an Electrical Permit
A permit isn’t just paperwork. It’s an official approval from your city or county allowing the work to move forward under safety rules.
Permits exist to:
- Ensure safety
- Provide documentation
- Verify code compliance
What Happens Without a Permit
Skipping a permit might save time at first, but it almost always backfires. You could face:
- City fines
- Utility refusal to reconnect service
- Denied insurance claims
Situations Where a Permit Might Not Be Needed
Minor Electrical Work That Typically Doesn’t Require a Permit
- Replacing a single breaker (not the main breaker)
- Adding or correcting a label inside the panel (no wiring changes)
- Tightening loose screws or connections in existing circuits
- Replacing a light fixture or ceiling fan (same voltage and wiring)
- Swapping out a receptacle or switch with the same type and amperage
- Replacing a fuse in a fuse box (same rating, no rewiring)
These minor repairs don’t change the panel’s design or how much power it handles.
When in Doubt, Ask
If you’re unsure, don’t guess. Call your local building department or ask your electrician. They can tell you instantly if your project needs a permit—and help you avoid mistakes that could cost time and money later.
How to Apply for an Electrical Permit
Step 1: Check How Your City Handles Permits
Most towns now use online portals, but some still allow in-person filing at the building department. Either way, the process can feel confusing for homeowners. That’s why many people let a professional handle it for them.
Electrical All Pro files permit for every panel upgrade we complete. We deal directly with the city, so you don’t have to stress over forms or confusing instructions.
Step 2: Gather the Right Details
Permits require a few key pieces of information:
- Property address for the work
- A simple project description, like “200‑amp panel upgrade”
- The electrician’s license number (required for most applications)
When you hire Electrical All Pro, we provide all the necessary license and insurance documentation up front, so there’s no delay.
Step 3: Submit, Pay, and Schedule
Once the paperwork is ready, the application gets filed—online or in person—and the permit fee (usually $50–$350) is paid. Your electrician then coordinates inspections. For panel upgrades, there are usually two: a rough‑in check and a final inspection.
Why We Handle It for You
Permits can be intimidating if you’ve never pulled one before. Electrical All Pro handles the entire process, from filing to final approval, so you don’t have to worry about missing steps or failing inspections.
Understanding Local Codes & Compliance Rules
National Electrical Code (NEC) Overview
The NEC is a nationwide standard that governs safe electrical installation. Every licensed electrician must follow it. It’s updated every three years to address new technology and safety concerns.
City & County Requirements
Local governments enforce the NEC, but they may add their own requirements, such as:
- Extra inspections
- Additional documentation
- Higher permit fees
Permit Fees and Approval Timeline
Fees usually range from $50–$350. Simple projects may be approved in a day or two, while larger ones take longer.
What Inspectors Look For
Before approval, inspectors verify:
- Proper grounding
- Correct wire sizes
- Breaker ratings
- Overall safety and code compliance
Why DIY Can Be Risky (and Even Illegal)
Working on a live electrical panel is one of the most dangerous jobs in a home. The panel connects directly to the utility’s power line, which means it stays energized even if the breakers are turned off. A single mistake can lead to severe electric shock, burns, or even death.
In many states, it’s also illegal for an unlicensed homeowner to perform major electrical work like a panel upgrade. Local codes require that any service involving the main electrical line or meter be done by a licensed electrician. Skipping that rule can lead to fines, voided insurance coverage, and work being red‑tagged by inspectors.
How Professionals Simplify the Process
A licensed electrician does far more than just swap out a box on the wall. They manage the entire upgrade from start to finish, ensuring everything is safe, legal, and efficient. Here’s what they handle:
- Pulls the correct permits. They submit the paperwork, pay the fees, and make sure the job is officially approved before work starts.
- Coordinates with the power company. The electrician arranges for the utility to shut off power for the upgrade and reconnect service afterward—saving you long hold times and scheduling headaches.
- Schedules and oversees inspections. Most panel upgrades require at least one or two inspections. The electrician meets the inspector, explains the work, and fixes any issues immediately.
- Ensures NEC and local code compliance. Every wire, breaker, and ground is installed to meet the National Electrical Code and any added local requirements.
- Handles safety from start to finish. From proper grounding to labeling every circuit, they make sure the panel is safe for your family for decades to come.
- Documents the work for records. You’ll have proof for insurance and resale that the upgrade was done by a licensed professional.
Costs Linked to Panel Permits & Upgrades
Permit‑Related Costs
Permit fees vary, typically ranging from $75 to $350, depending on location and project scope.
Other Cost Factors
Average costs for panel upgrades:
- 100 amps: $850–$1,600
- 200 amps: $1,300–$3,000
- 400 amps: $3,800–$7,000+
Add-ons like grounding rods or rewiring increase costs.
Planning Your Panel Upgrade the Right Way
Before any work begins, a licensed electrician must determine how much power your home truly needs. This process, called a load calculation, takes into account the size of your home, the number of rooms, and every major appliance that draws electricity.
Your HVAC system, oven, water heater, and even future plans—like installing an EV charger, hot tub, or workshop—are part of the equation. This step prevents costly mistakes, ensuring the new panel isn’t too small to handle your demand or unnecessarily large, which would increase costs without benefit.
Upgrading an electrical panel also involves coordination with your utility company. The power supply to your home has to be shut off before work begins, and it won’t be restored until the job is complete and the inspection is approved. If you’re increasing your home’s service from 100 to 200 amps—or even higher—the utility must also confirm that the neighborhood lines can support the added load.
Once the upgrade is done, the inspector signs off, and the power company reconnects your home to the grid.
Working With the Power Company
Your utility company must:
- Shut off the power before work
- Reconnect service after inspections
A professional will coordinate all this on your behalf.
Conclusion
Upgrading an electrical panel isn’t just about adding more power—it’s about doing it safely and legally. Permits might seem like red tape, but they protect your home, your family, and your investment.
When handled by a qualified electrician, the process becomes simple and worry-free. Now that you understand the steps, risks, and requirements, are you ready to upgrade the right way?
