Residential Electrician Services: What They Cover and the Security System Connection
A licensed residential electrician charges $75 to $150 per hour nationally, with most residential service calls running $150 to $500 for routine work and $500 to $2,500 for larger projects. These aren't arbitrary numbers — they reflect real labor market conditions, the cost of a licensed tradesperson with continuing education requirements, and the liability that comes with working inside the systems that power your home. When electrical work is done wrong, the consequences range from nuisance (tripped breakers) to catastrophic (house fires).
Residential electrician services cover everything from replacing a single outlet to whole-home rewiring, and the scope of what qualifies as "electrical work" overlaps meaningfully with home security installation. Modern security systems require more electrical support than earlier generations: wired cameras need power runs, smart doorbells need dedicated circuits, whole-home backup systems need panel work, and hardwired smoke and CO detectors need circuit connections. Understanding what electrical services cost, when you need a licensed electrician versus a security technician, and how to coordinate both trades will save you time and money.
Core Residential Electrical Services and Costs
Panel upgrades are among the most common and impactful residential electrical projects. Most homes built before 1990 have 100-amp service. Modern homes with EV charging, large HVAC systems, and whole-home generators often need 200-amp service or more. A 100-amp to 200-amp panel upgrade costs $1,500 to $3,000 installed nationally. Going from 200-amp to 400-amp for large homes runs $3,500 to $7,000.
Outlet and circuit installation is bread-and-butter residential electrical work. Adding a single 20-amp circuit costs $200 to $500 depending on how far the run goes from the panel. Adding a dedicated 240V circuit for an EV charger, range, or dryer costs $300 to $700. A whole-house GFCI and AFCI update (adding arc-fault and ground-fault protection to existing circuits) costs $800 to $2,500 for a typical home depending on the number of circuits.
Wiring repairs and troubleshooting cover everything from diagnosing a dead outlet ($75 to $200 for a service call plus parts) to identifying and repairing damaged wiring in walls. Aluminum wiring issues in homes built in the late 1960s and early 1970s require specific remediation; a full aluminum wiring remediation for a typical 1,500-square-foot home costs $1,500 to $4,000.
Lighting installation includes recessed lighting, ceiling fan installation, and exterior security lighting. Recessed lighting installation runs $100 to $250 per fixture for a licensed electrician. Ceiling fan installation with new wiring runs $200 to $400. Exterior security lighting installation on an existing exterior circuit runs $150 to $350 per fixture.
Generator hookup involves installing a transfer switch and connecting a standby or portable generator to your home's electrical system. A manual transfer switch installation costs $400 to $900. An automatic transfer switch for a standby generator costs $500 to $1,500 for the switch installation, separate from the generator and generator installation.
Where Electrical and Security Work Intersect
Security systems in 2026 are sophisticated electrical consumers. A comprehensive home security installation typically includes wired motion sensors, hardwired door and window contacts, security cameras (both PoE network cameras and 12V analog cameras), a central panel with battery backup, hardwired smoke and CO detectors, a smart doorbell, and exterior keypads. This equipment needs power.
The electrical requirements for a security system installation fall into several categories. Low-voltage wiring (12V to 24V DC) for sensors and cameras can typically be run by security technicians without electrical licensing in most states. Line-voltage work (120V AC) for security camera power supplies, panel power feeds, and dedicated security system circuits requires a licensed electrician.
Dedicated circuit installation for a security panel: $250 to $500. Hardwired smoke and CO detector installation on a new circuit: $400 to $800 for a typical home. Exterior camera power runs (line-voltage from interior to exterior mounting locations): $150 to $300 per location. Smart doorbell wiring (if your existing doorbell wiring is inadequate for a video doorbell): $200 to $400.
The practical implication: a comprehensive security installation in a home that needs new circuits and panel work should involve both a licensed electrician and a security installer. Having them coordinate upfront saves money compared to doing the electrical work after the security company has already identified the shortcomings.
Electrical Code and Permit Requirements
Residential electrical work of any significance requires permits in most US jurisdictions. The permit requirement exists because electrical work that fails inspection isn't just a code violation — it's a fire hazard and an insurance liability. Unpermitted electrical work discovered during a home sale can require remediation at the seller's expense or become a negotiating issue.
Permitted electrical work is inspected by a local building inspector who verifies that the installation meets code. This is the oversight mechanism that ensures the work was done correctly. Licensed electricians handle permit filing as a routine part of their work. If a contractor offers to skip permits to save time or money, walk away.
The National Electrical Code (NEC) is updated every three years and adopted by states on varying schedules. The 2023 NEC includes requirements for EV charger readiness in new construction and significant updates to AFCI and GFCI requirements. A licensed electrician practicing in your state will be current on the adopted code version.
Security-Specific Electrical Considerations
A whole-home security system installation benefits from an electrical assessment before installation begins. The questions to address: Does the security panel location have an appropriate power source? Does the camera installation plan require new line-voltage runs? Is the existing electrical panel in good enough condition to support new circuits without issues?
Homes with older panels (particularly Federal Pacific Stab-Lok or Zinsco panels, both of which have documented reliability issues) should address panel replacement before investing heavily in security system infrastructure. Installing a high-end security system on a compromised electrical panel is working at cross-purposes.
The coordination workflow that works best: hire a security company to design the system, get their electrical requirements list (circuits needed, power locations needed), then have a licensed electrician bid the electrical rough-in work. Security installation happens after the electrical work is complete and inspected.

Frequently Asked Questions
Do I need a licensed electrician to install security cameras? For low-voltage cameras that run on Power over Ethernet (PoE) or 12V DC from a nearby power supply, most states allow security technicians to do the installation without electrical licensing. For cameras that require a new line-voltage circuit, a hardwired 120V power supply, or any work in your electrical panel, a licensed electrician is required. When in doubt, check your state's licensing requirements for low-voltage contractors versus electrical contractors.
What electrical work is required for a hardwired home security system? At minimum, the security panel needs a dedicated power circuit (typically 20 amps). Hardwired smoke and CO detectors need circuit connections. Exterior cameras that need line-voltage power need new runs. A security system with backup power and monitoring also needs a clear path for the backup battery system. A security company doing a proper assessment will identify all of these requirements upfront.
How do I find a licensed residential electrician? Your state's electrical licensing board maintains a public lookup tool. Search "[your state] electrical contractor license lookup" to find the official verification portal. Verify that any electrician you hire holds a current state license. For permit-required work, verify they've pulled permits on other jobs by asking to see recent permit examples or asking for references who can confirm the contractor pulled permits and passed inspection.
Can I save money by having the security company do the electrical work? Security companies that hold electrical licenses can do both. Many don't. A security company that does electrical work without appropriate licensing creates liability for you as the homeowner — unpermitted or unlicensed electrical work is your problem at sale or in an insurance claim. Verify credentials before allowing any contractor to do work outside their licensed scope.
What's the difference between line-voltage and low-voltage electrical work? Line voltage is 120V or 240V AC from your home's electrical system. Low voltage is typically 12V to 24V DC from a transformer or power supply. Line-voltage work requires electrical licensing in all US states. Low-voltage work (structured wiring, security systems, thermostat wiring) is regulated separately in most states, typically under a low-voltage or systems contractor license. The distinction matters for both safety and code compliance.
