Materials: The cost of materials for GFCI outlet installation generally falls between $15 and $50 per unit. While labor is the primary expense, investing in quality materials is crucial for safety and compliance with electrical regulations.
Outlet Size: GFCI outlets are available in different sizes, each tailored for specific uses. Below are some examples and their typical material costs:
| Best Use | Amp Rating | Average Cost (Materials Only) |
| Living room, bedroom, bathroom | 15-amp | $15–$30 |
| Kitchen appliances, utility room | 20-amp | $17–$40 |
| Outdoor applications (pool, hot tub, etc.) | Outdoor | $15–$35 |
| Bathroom and kitchen (with switch) | Switch | $20–$40 |
| Smart home devices | Smart | $25–$50 |
Number of Outlets: The total number of GFCI outlets needed greatly affects the overall costs. Electricians might provide discounts for multiple installations, and only the first outlet on each circuit is required to have GFCI protection.
Labor Costs: Electricians typically charge between $50 and $100 per hour.
“Some may charge by the outlet, while the minimum service fee usually ranges from $100 to $200” – says Chris Almasan from Service Trade Pros, “making it beneficial to group several electrical tasks during one visit.”
Replacing vs. Installing New Outlets
Replacing an existing outlet with a GFCI outlet usually costs between $100 and $200 and is generally straightforward. However, installing a new GFCI outlet can be more complex and costs between $150 and $300, primarily due to additional wiring and installation time.
Indoor vs. Outdoor GFCI Outlet Installation
The average cost for installing an indoor GFCI outlet is around $210, while outdoor installations can vary significantly from $300 to $1,400, depending on requirements such as waterproof boxes and drilling needs.
| Component | Outdoor Cost Range |
| Materials | $15–$35 |
| Waterproof outlet cover | $10–$20 |
| Electrician labor costs | $50–$100 per hour |
| Moving an outlet | $200–$300 |
Permit and Inspection Costs
Electrical permits may be necessary, especially for new installations, with costs ranging from $50 to $400 based on local regulations and project complexity. While inspections are often included in the electrician’s fees, a separate inspection can average around $150.
Necessary Tools
Essential tools for GFCI outlet installation include wire strippers, a voltage tester pen, and screwdrivers, costing around $100 in total. If you lack the right tools or experience, it’s wise to hire a licensed electrician.
DIY vs. Professional Installation
- DIY: If you have electrical experience, you can replace an existing outlet with a GFCI outlet on your own. Required tools include wire strippers, a voltage tester pen, and a screwdriver. While this task is simpler than new installations, there are risks involved, including injury or damage.
- Hiring a Professional: For those without electrical experience, hiring a licensed electrician is advisable for safety and correctness. The average professional installation cost ranges from $130 to $300, covering labor, materials, and peace of mind that your home is safe from electrical hazards. Professionals possess the necessary skills and tools to handle the task safely and ensure compliance with safety regulations.
Required Locations for GFCI Outlets
GFCI outlets are crucial for safety in several key areas of a home:
- Bathrooms: All outlets must have GFCI protection.
- Kitchens: At least two 20-amp circuits are required for small countertop appliances, with any outlets within six feet of a sink needing GFCI protection.
- Laundry Rooms: Outlets should be on a 30-amp, 240-volt circuit with four conductors, requiring GFCI protection for all outlets.
- Garages: Each car space should have at least one GFCI-protected outlet.
