How Much Does It Cost to Install a GFCI Outlet?

$130 to $350 per outlet is the typical cost for GFCI outlet installation, with the national average around $200. Replacing an existing standard outlet with a GFCI outlet costs $130 to $180 when the wiring is already in place. Installing a brand new GFCI outlet where no outlet exists runs $250 to $350 or more because the electrician needs to run new wiring from the breaker panel or a nearby junction box.

The GFCI device itself is the cheap part, typically $12 to $25 at any hardware store. Labor is what drives the cost. Electricians charge $50 to $100 per hour, and even a straightforward swap takes 20 to 45 minutes per outlet once you account for testing and cleanup. If you need multiple outlets installed, most electricians offer a lower per-outlet rate since they are already on site.

GFCI Outlet Installation Cost by Type

$130 to $400 per outlet depending on the installation scenario. Here is how costs break down for the most common situations homeowners face.

Installation TypeCost Per OutletWhat's Involved
Replace standard outlet with GFCI$130 - $180Swap existing outlet for GFCI device, test, verify grounding. Takes 20-30 minutes.
New GFCI outlet (run new wire)$250 - $400Run wire from panel or junction box, cut opening, install box and outlet. Takes 1-3 hours.
Outdoor GFCI outlet$250 - $350Install weatherproof GFCI with in-use cover. May need conduit and exterior-rated box.
GFCI breaker instead of outlet$150 - $300Install GFCI breaker at panel to protect entire circuit. No outlet swap needed.

If you are doing a full electrical panel upgrade ($1,500 to $4,000), ask the electrician to add GFCI breakers at the same time. It is cheaper to protect entire circuits with GFCI breakers during a panel swap than to install individual GFCI outlets throughout the house later.

GFCI Outlet Cost by Device Type

$12 to $50 per device for the GFCI outlet itself. The type of GFCI outlet you choose affects both the material cost and the protection level.

GFCI Outlet TypeDevice CostBest For
Standard GFCI$12 - $20Indoor locations like kitchens, bathrooms, and basements. Most common choice.
Weather-resistant GFCI$18 - $30Outdoor locations, garages, and covered patios. Required by code for exterior use.
Self-test GFCI$20 - $35Any location. Automatically tests itself and indicates failure. Now required by 2020 NEC.
GFCI with USB ports$25 - $50Kitchens, offices, and bedrooms where you charge devices. Combines GFCI protection with USB charging.

Self-testing GFCI outlets are the current standard. The 2020 NEC update requires all new GFCI outlets to have self-test capability. If you are installing new outlets, go with self-test models to stay ahead of code requirements. The price difference is only $5 to $10 more than a standard GFCI.

Where Are GFCI Outlets Required?

$300 to $1,200 total for a typical home covers GFCI outlets in all 4 to 8 required locations per the National Electrical Code. Here is every location where GFCI outlets are required.

LocationNEC RequirementTypical # of Outlets
KitchenAll outlets within 6 feet of a sink2 - 4
BathroomsAll bathroom outlets1 - 2 per bathroom

OutdoorsAll outdoor outlets1 - 4

Near pools/hot tubsAll outlets within 20 feet1 - 2

You do not need a GFCI device at every single outlet. One GFCI outlet can protect all downstream outlets on the same circuit. An electrician can wire the first outlet on a circuit as a GFCI, and every outlet after it on that circuit gets GFCI protection automatically. This saves money on a whole-house upgrade because you might only need 4 to 6 actual GFCI devices to cover 15 to 20 outlet locations.

Factors That Affect GFCI Outlet Installation Cost

$130 to $400+ per outlet is the full range, and several factors push your price higher or lower.

Number of Outlets

Electricians give better per-outlet pricing when you have multiple outlets done in one visit. A single GFCI outlet replacement might cost $150 to $180. But if you have the electrician swap out 5 or 6 outlets at once, the per-outlet cost drops to $100 to $130 each because the service call fee gets spread across more work. If you need GFCI outlets and are also planning recessed lighting installation ($150 to $300 per light), booking both jobs with the same electrician saves on the service call.

Wiring Condition

GFCI outlets work best with properly grounded wiring. In homes built before 1965, you may have ungrounded two-wire circuits. GFCI outlets can still be installed on ungrounded circuits (they protect against ground faults but not equipment grounding), but the electrician needs to label them "No Equipment Ground." If you want full grounding, running a ground wire to each outlet adds $50 to $150 per outlet.

Wall Accessibility

Outlets on interior walls with open access above or below (like an unfinished basement or accessible attic) are easy and cheap to wire. Outlets on exterior walls, in finished ceilings, or in areas with limited access cost more because the electrician has to fish wire through walls, potentially cutting and patching drywall. Difficult-access locations add $50 to $150 per outlet.

Permit Requirements

Some jurisdictions require an electrical permit for new outlet installations. Permits cost $50 to $150 and may require an inspection after the work is done. Replacing an existing outlet with a GFCI typically does not require a permit in most areas, but adding a new outlet or running new wire usually does. Check with your local building department.

Frequently Asked Questions

How much does it cost to install a GFCI outlet?

GFCI outlet installation costs $130 to $350 per outlet on average, with the national average around $200. A simple replacement where you swap a standard outlet for a GFCI costs $130 to $180. New installations that require running wire cost $250 to $350 or more depending on the distance from the panel and wall accessibility.

Where are GFCI outlets required by code?

The National Electrical Code (NEC) requires GFCI protection in bathrooms, kitchens (within 6 feet of a sink), garages, outdoors, basements, crawl spaces, laundry areas, and near pools or hot tubs. Any outlet within 6 feet of a water source must have GFCI protection. Older homes may not have GFCI outlets in all required locations, and upgrading is strongly recommended for safety.

Can I install a GFCI outlet myself?

Yes, replacing an existing standard outlet with a GFCI outlet is a common DIY project. The outlet itself costs $12 to $25, and the swap takes about 20 to 30 minutes if you are comfortable working with wiring. Turn off the breaker first and test with a voltage tester. However, running new wiring for a GFCI outlet in a location that does not have an existing outlet should be done by a licensed electrician.

What is the difference between a GFCI outlet and a regular outlet?

A GFCI (Ground Fault Circuit Interrupter) outlet monitors the current flowing through it and shuts off power within milliseconds if it detects a ground fault, which can happen when electricity flows through water or a person. Regular outlets have no such protection. GFCI outlets have "Test" and "Reset" buttons on the face. One GFCI outlet can protect multiple downstream outlets on the same circuit.

How many GFCI outlets do I need?

Most homes need 4 to 8 GFCI-protected outlets. You do not need a GFCI outlet at every location because one GFCI outlet can protect all downstream outlets on the same circuit. A typical setup is one GFCI outlet per circuit in the kitchen (usually 2 circuits), one in each bathroom, one in the garage, and one for outdoor outlets. An electrician can wire a single GFCI to protect the entire circuit, reducing the number of GFCI devices you need to buy.
