Yes. Most jurisdictions, including those in Spokane and Northern Idaho, require a permit for permanent electrical work on outbuildings. Mainstream handles permitting and safe, code-compliant installations from start to finish.
Extension cords are designed for temporary, short-term use and are not built to handle continuous electrical loads. Using an extension cord to power a shed or garage long term can increase the risk of overheating, electrical damage, or fire, especially when powering tools, lighting, or appliances.
Permanent power for a shed or garage typically involves running a properly sized electrical circuit from the main panel, using approved wiring methods and grounding. This ensures the electrical system can safely support the intended use while complying with local electrical codes.
Installing a dedicated circuit also allows for proper outlets, lighting, and safety protections such as breakers and GFCI protection where required. A licensed electrician can evaluate power needs and ensure the installation is safe and code-compliant.
Outdoor circuits can support lighting, outlets, EV chargers, hot tubs, irrigation systems, and more. Mainstream designs outdoor power solutions tailored to your needs—with safety built in.
It involves trenching, conduit installation, grounding, and weatherproof connections—all up to code. Mainstream’s licensed electricians ensure the job is done safely and built to last.
If you’ve invested in a backyard shed, detached garage, greenhouse, or ADU, there’s a good chance you’ve also thought about how to make that space truly functional. Whether you’re dreaming of a fully lit workshop, a powered office, or just need to keep your tools charged, running electric to a shed can open the door to all kinds of possibilities. And with the right team behind you, it doesn’t have to be complicated.
At Mainstream Electric, Heating, Cooling and Plumbing, we’ve been bringing dependable power to outbuildings across Spokane County and Northern Idaho since 2000. From trenching and conduit installation to panel upgrades and proper permitting, we handle every detail—safely, efficiently, and with your long-term satisfaction in mind.
Installing power to an outbuilding isn’t just about stringing wires—it’s about designing a system that’s safe, compliant, and right-sized for how you’ll actually use the space. Our licensed electricians start with a site assessment, where we consider distance from your main panel, intended use, local codes, and any potential obstacles like terrain or landscaping.
From there, we create a custom plan that may include:
Installing a dedicated subpanel
Laying buried or overhead conduit between structures
Adding outlets, lighting, and switches
Ensuring proper grounding and surge protection
Integrating smart or energy-efficient systems
If your current service panel is maxed out or nearing its limit, we’ll also assess whether you’d benefit from a full electrical panel upgrade to support additional load capacity.
The best time to run power is before you need it. If you’re building a new structure, planning a renovation, or just tired of dragging extension cords through the yard, it’s probably time to act. We regularly help homeowners connect power for:
Tool sheds and workshops
Home offices and creative studios
Detached garages and carports
Hobby greenhouses
Backyard guest suites or ADUs
Even if your plans are small for now, we can future-proof your system so it’s ready for growth—whether that means adding heating, air conditioning, or smart home tech down the line.
Running electricity to a shed involves more than digging a trench. It typically requires permits, inspections, and code compliance every step of the way. With Mainstream, you don’t have to worry about that. We handle all permitting and ensure your installation meets the latest local and national electrical standards.
Our team will also conduct a full home electrical inspection before beginning work to verify that your current system is safe and capable of supporting the upgrade.
Powering a shed or structure is an investment in your property, and the quality of the electrical work matters. That’s why our electricians use top-tier materials and meticulous techniques to ensure longevity and reliability. From secure conduit runs to water-resistant outlets and GFCI installations, we don’t cut corners—and we don’t leave a mess behind.
We also offer integrated whole-home surge protection and smoke and carbon monoxide detector updates for detached structures where safety is critical.
Unexpected issues don’t always follow business hours. If your newly powered shed experiences sparks, loss of power, or smells like something’s burning, don’t wait—our 24-hour emergency electrical service is always available. With quick dispatch, stocked trucks, and licensed pros, we’ll restore safety fast.
