Can I Run Electricity to My Shed? A Homeowner’s Guide to Safe Wiring [2025]

Many homeowners want to power their sheds. You can electrify your backyard structure into a functional workspace or storage area. The project costs between $100 to $600, depending on your setup and requirements.

Your shed’s electrical setup needs one of three options: permanent wiring from your home, a generator, or solar panels. Safety matters as much as convenience. Local authorities require permits and inspections to verify that your wiring meets safety standards. The National Electrical Code mandates specific burial depths for electrical wiring – 12 to 24 inches based on installation type. This piece walks you through the essentials of powering your shed safely, whether you plan to DIY or hire professionals.

Understanding Legal and Safety Requirements

You need to understand legal requirements and safety measures before powering your shed with electricity. This knowledge will protect your property and everyone who uses your outdoor space.

Do you need a permit to run electricity to a shed?

The short answer is yes. Most local jurisdictions ask for electrical permits when adding power to outdoor structures. These permits will provide a way to check if your installation meets safety standards and local building codes. Your local building department can help you understand the specific requirements in your area.

Permits serve as more than just paperwork—they protect your project. They make sure your electrical installation meets the safety and code requirements set by local authorities. The smart move is to check with your local building department for even minor electrical work to avoid fines or safety problems down the road.

Why safety should be your first concern

Outdoor shed wiring comes with unique challenges like weather exposure, temperature changes, and moisture. Bad wiring can create dangerous situations that lead to electrical fires, shock hazards, or equipment damage.

The National Electrical Code (NEC) sets specific rules for outdoor structures. These rules cover proper working space around electrical equipment, the right disconnecting methods, and correct grounding procedures. Meeting these standards isn’t optional—it helps prevent accidents.

Smoke and carbon monoxide detectors in your shed give vital protection against possible hazards. Regular checks of these devices make sure they work when you need them most.

When to hire a licensed electrician

DIY projects can be fun, but electrical work needs special knowledge. You should call a professional electrician if you:

• Need to install a subpanel
• I’m not sure about electrical codes
• Have complex or high electrical load needs
• Need to trench and install underground feeds

Licensed electricians know NEC standards, own proper tools and equipment, and can guide you through permit processes quickly. They can tell if your home’s power supply can handle your shed’s needs and suggest the best spots for outlets, switches, and lighting.

Professional installation costs less than fixing problems from bad DIY wiring that could damage property or cause injuries.

Choosing the Right Power Source for Your Shed

You need to think over several options to power your shed based on what you need. Let’s look at three ways you can wire your shed with electricity.

Using a generator: pros and cons

Generators give you a simple way to power your shed without permits or an electrician’s help. You’ll need to add up the total wattage of your tools and equipment to figure out your power needs. These units are simple to use, but they do have some big drawbacks.

Pros:

• Easy setup: place it outside, add fuel, and plug in an extension cord
• No need for permits or professional help
• Move it around as your needs change

Cons:

• Fuel costs add up quickly
• Noise levels can bother your neighbors
• Breaks down often and needs regular care
• Toxic fumes make indoor use dangerous
• The weather can damage the unit without proper cover

Solar panels: when they work best

People love solar power systems for their sheds, especially if the shed sits far from other buildings. A typical solar setup has panels, batteries to store power, and an inverter.

Pros:

• Clean energy with no emissions
• Runs without making noise
• Needs little care beyond cleaning panels
• Power costs nothing after setup
• Safe to use inside

Cons:

• Costs more upfront (basic shed kits start under $1,000)
• Makes less power on cloudy days or in the shade
• Might not run big power tools unless sized right

Basic solar setups that run off-grid usually don’t need permits. A 200W panel system makes about 700- 800Wh each day, which works great for LED lights and small devices.

Running permanent wiring from your home

Your home’s electrical panel can power your shed reliably, but it takes more work to set up.

Pros:

• Steady power that doesn’t need fuel or sun
• Runs heavy electrical loads
• Lasts long with no extra maintenance

Cons:

• You’ll need permits and likely professional help
• Digging trenches for underground wires takes work
• Set up costs more, especially for sheds far away
• Older homes with full panels might need another meter

So your best choice comes down to where your shed sits, what you can spend, and how much power you need.

How to Run Electricity to a Shed: Step-by-Step

“The number of circuits, the amperage required, and other specifics about the power service to the building are all determined based on what the shed will be used for and what tools, equipment, or appliances will be run in the building.” — Gilmore Electric Express, Professional electrical service provider

You need to follow several steps to run electricity to your shed safely and effectively. Let’s make this process easier by breaking it down into manageable tasks.

Planning the route and load requirements

Start by making a list of all devices and tools you’ll use in your shed to assess your electrical needs. Calculate the total wattage requirements to figure out the right circuit size. A 20-amp circuit works well for most simple sheds with lighting and small tools. Your shed might need a 50-60 amp service if you plan to use power tools or heaters.

The next step is to map out the shortest route from your home’s electrical panel to your shed. You should minimize the bends in your wiring path. The NEC states that total bends should not exceed 360 degrees, and 90-degree elbows take up 180 degrees of this allowance.

Digging trenches and laying conduit

Make sure to call 811 to locate underground utilities before you start digging. The trench depth requirements vary based on your wiring method:

• Rigid metal conduit: 6 inches deep
• Underground feeder cable with GFCI protection: 12 inches
• PVC conduit: 18 inches

Place 2 inches of sand at the trench bottom to protect the conduit. Use a hole saw to install conduit through your house and shed walls. Add caution tape above the sand layer before you fill the trench back up.

Installing a subpanel and outlets

The subpanel should sit between wall studs about 6 feet above the floor. Run the feeder cable from your main panel to the subpanel and leave about 2 feet of extra cable at each end.

Connect each wire in the subpanel to its designated bus bar. The white neutral wire goes to the neutral bus, the ground wire to the ground bus, and the hot wires connect to the hot bus bars.

Grounding and weatherproofing

Your shed’s electrical system needs proper grounding with a separate ground rod outside. Use duct seal or exterior-grade acrylic-latex caulk to seal all entry points where conduit enters buildings. This prevents water from getting in.

The final step requires installing GFCI-protected outlets, which the code requires for all outdoor structures.

Common Questions About Wiring a Shed for Electricity

You probably have questions about implementation after learning the simple basics of powering your shed. Let’s look at the most common questions about shed wiring projects.

Can I use an extension cord temporarily?

You can use an extension cord to power your shed temporarily if the cord is outdoor-rated. The cord works fine for occasional use, like clearing out your shed or using power tools for a specific project. All the same, note that extension cords work only for temporary use, and you must unplug and remove them after each use.

Extension cords create several safety risks when left out permanently:

• They become tripping hazards
• You cannot legally bury them underground
• UV damage and rodents can destroy them
• Overloading leads to overheating
• Damage can expose dangerous wiring

What size wire do I need?

We determined wire size based on distance and load requirements. A typical shed about 100 feet from your home with simple lighting and outlets needs:

• 6 AWG copper wire for a 20-amp circuit at 120V to maintain acceptable voltage drop
• 10 AWG copper for runs under 70 feet to keep the recommended 3% or less voltage drop
• Aluminum wire (like a 2-2-2-4 mobile home feeder) offers a budget-friendly option for runs over 150 feet

Individual wires inside conduit need a THWN (thermoplastic/wet location/nylon jacket) rating for underground installations.

How deep should I bury the cable?

Your wiring method determines the required burial depth:

• 6 inches deep for rigid metal conduit with insulated wires
• 12 inches deep for UF cable with GFCI protection
• 18 inches deep for PVC conduit with insulated wires
• 24 inches deep for direct-buried UF cable without conduit

Warning tape placed above buried wiring prevents future digging accidents.

How much does it cost to wire a shed?

DIY installations cost between USD 100 to USD 600. Professional installation ranges from USD 1,200 to USD 7,100 based on:

• Your home’s distance
• Installation type (overhead vs. underground)
• The shed’s size
• Required circuit numbers
• Subpanel requirements

DIY projects’ main costs come from materials like conduit (USD 0.77-1.60 per foot) and wiring (USD 20-100 based on length and gauge).
