Bedroom Electrical Code Requirements

NEC 2017 to 2023 rules for outlets, AFCI, lighting and smoke alarms, with an outlet layout calculator and a printable inspection checklist.

Which NEC edition is your town on?

Same bedroom rules again. Check local amendments: some states delay or trim AFCI requirements.

Your building department enforces one edition, sometimes with amendments. Call or check its website before you buy breakers.

Wall runs between doors and openings (ft, comma separated)

Measure each stretch of wall along the floor between doors, closets and other openings. Walls 2 ft and wider count.

4 receptacles minimum

Wall 1, 12 ft: 1 at 6 ft
Wall 2, 9 ft: 1 at 4.5 ft
Wall 3, 12 ft: 1 at 6 ft
Wall 4, 12 ft: 1 at 6 ft

Wire a bedroom: 4 receptacles on an AFCI circuit

45 ft of wall in 4 runs needs at least 4 receptacles under the 6 ft rule (NEC 210.52(A)), all tamper-resistant, on an AFCI-protected circuit (210.12(A)), with a switched light at the door and a smoke alarm.

6 steps 5 tools 7 materials

1
Check the permit and your code edition
New circuits and added outlets are usually permitted work. Ask which NEC edition your town enforces and whether it amends the AFCI rules.
- Permit issued or not needed
- NEC edition noted
2
Lay out receptacles
Mark at least 4 receptacles so no point along the floor line is more than 6 ft from one; count every wall 2 ft or wider. Put extras where the bed and desk will go.
- Wall 1 (12 ft): 1 receptacle
- Wall 2 (9 ft): 1 receptacle
- Wall 3 (12 ft): 1 receptacle
3
Plan lighting and the switch
A wall switch at the entry controls a ceiling light or a switched receptacle (210.70(A)(1)). Use a fan-rated box for a ceiling fan.
- Switch at the door
- Fan-rated box if a fan is planned

AFCI: what counts as an outlet

Item	AFCI?	Code	Note
Receptacle	Yes	210.12(A)	Combination AFCI breaker, or a listed AFCI receptacle first on the run where allowed
Ceiling light	Yes	210.12(A)	A lighting outlet is an outlet; the whole circuit is protected
Ceiling fan	Yes	210.12(A)	Same circuit rule as the light
Smoke alarm (hardwired)	Yes	210.12(A)	If it is on a bedroom circuit; AFCI is not a reason to leave it off
Switched receptacle	Yes	210.12(A), 210.70(A)(1) Ex. 1	Can replace the ceiling light as the required switched lighting outlet
240 V baseboard heater or window AC	No	210.12(A)	The rule covers 120 V, 15 and 20 A circuits only

Exceptions and edge cases

240 V baseboard heat and 240 V window AC circuits need no AFCI.
Extending or modifying a bedroom circuit more than 6 ft: add AFCI at the breaker or as the first outlet (210.12(D)).
A switched receptacle can stand in for the ceiling light (210.70(A)(1) Exception 1).

AFCI type	Cost	Use it
Combination AFCI breaker	$40 to $60	Protects the whole circuit from the panel; the default for new circuits
Dual-function (AFCI and GFCI) breaker	$50 to $70	Where a circuit needs both, such as a bedroom circuit that also feeds a laundry or wet bar receptacle
Outlet branch circuit (AFCI receptacle)	$35 to $45	First outlet on an existing circuit when you extend or replace (210.12(D)); also for older panels with no AFCI breaker

Bedroom electrical code at a glance

Rule	Requirement	Code
Receptacle spacing	No point along the floor line more than 6 ft from a receptacle; every wall space 2 ft or wider counts	210.52(A)
AFCI	All 120 V, 15 and 20 A circuits feeding outlets or devices in the bedroom	210.12(A)
Extending a circuit	Add AFCI (breaker or first-outlet device) when extending or modifying a bedroom circuit more than 6 ft	210.12(D)
Replacing a receptacle	A replacement where AFCI is now required must be AFCI-protected (AFCI receptacle or breaker)	406.4(D)(4)
Tamper-resistant	All 15 and 20 A, 125 V receptacles; except those more than 5.5 ft above the floor	406.12
Switched lighting	A wall switch at the entry controlling a ceiling light or a switched receptacle	210.70(A)(1)
Smoke alarms	In each bedroom, outside each sleeping area and on every level; hardwired and interconnected in new work	IRC R314
CO alarms	Outside each sleeping area where there is a fuel-burning appliance or an attached garage	IRC R315
GFCI	Not required for bedroom receptacles, except within 6 ft of a sink	210.8(A)

Circuits, heights and lighting

Common bedroom circuits

Receptacles and lights: 15 A on 14 AWG or 20 A on 12 AWG, AFCI; may serve more than one bedroom
Ceiling fan: on the room circuit; 14/3 or 12/3 for separate fan and light switches
Window AC: 15 or 20 A, its own circuit recommended; 240 V units need no AFCI
Space heater over 1,500 W: dedicated 20 A or a hardwired 240 V heater
Smoke and CO alarms: on a lighting circuit, interconnected

Typical heights

Switches: 48 in. to center (ADA reach 15 to 48 in.)
Receptacles: 12 to 16 in. to center
Nightstand receptacles: 26 to 30 in., beside the bed
Desk: 26 to 30 in.; TV wall: 42 to 48 in.

Closet lights

Enclosed LED fixtures at least 6 in. from the storage space, 12 in. for surface incandescent; no pendants or bare lamps (410.16).

Inspection checklist

AFCI breaker or AFCI first outlet on every bedroom circuit, and it trips on test
No point on any wall more than 6 ft from a receptacle
Every receptacle tamper-resistant
Wall switch at the entry controlling a light or a switched receptacle
Fan-rated box for any ceiling fan
Smoke alarm inside the room, hardwired and interconnected in new work

Size the wire for long runs with the voltage drop calculator and check the panel with the electrical load calculator. For GFCI contrasts see the kitchen and bathroom electrical code sheets; for a fan, the ceiling fan installation guide.

Frequently asked questions

Do bedroom outlets need AFCI?

Yes. NEC 210.12(A) requires AFCI protection on every 120 V, 15 and 20 A branch circuit supplying outlets or devices in a bedroom: receptacles, lights, fans and hardwired smoke alarms. 240 V heaters and AC circuits are not covered. Most towns enforce this; a few amend it, so check locally.

How far apart do bedroom outlets need to be?

No point along the floor line of a wall may be more than 6 ft from a receptacle (210.52(A)), which works out to one every 12 ft. Any wall space 2 ft or wider counts, including short walls between doors. Space behind a door swing still counts as wall.

Is a light switch required at the bedroom door?

Yes. 210.70(A)(1) requires at least one wall-switch-controlled lighting outlet. The switch goes at the entry, and the exception allows a switched receptacle instead of a ceiling light. Rooms with two entries usually get three-way switches.

Do bedroom outlets need GFCI?

No, not as a rule. The NEC requires GFCI in bathrooms, kitchens, laundry areas and similar wet spots, not bedrooms. A bedroom receptacle within 6 ft of a sink, such as a wet bar, needs GFCI, and a dual-function breaker covers both.

Does a ceiling fan need AFCI?

Yes. A bedroom ceiling fan is an outlet on a bedroom branch circuit, so the circuit needs AFCI protection under 210.12(A). In practice the combination AFCI breaker for the room covers the fan, the light and the receptacles together.

Do I need to upgrade to AFCI when I replace an outlet?

Under 406.4(D)(4), replacing a receptacle in a location that now requires AFCI means providing it: an AFCI receptacle, an AFCI breaker or a listed outlet-branch-circuit AFCI first on the run. Like-for-like swaps are where many towns look closely.

How many outlets can go on one bedroom circuit?

The NEC sets no limit for dwellings. A common rule of thumb is 8 to 10 on a 15 A circuit and 10 to 13 on 20 A. Plan on what will be plugged in: a window AC or a space heater wants its own circuit.

Do I need a permit to add a bedroom outlet?

Usually, yes, for any new outlet or circuit; replacing a device like for like often needs none. Many places let a homeowner pull an electrical permit for their own home, with a rough-in inspection before drywall and a final.

What counts as an outlet for AFCI?

Any point where current is taken to supply equipment: receptacles, light fixtures, ceiling fans and hardwired smoke alarms all count. That is why the whole bedroom circuit, not just the receptacles, needs AFCI.

Where do smoke alarms go in a bedroom?

IRC R314 requires one inside each bedroom, one outside each sleeping area and one on every level, hardwired with battery backup and interconnected in new work. Add a CO alarm outside sleeping areas when there is a fuel-burning appliance or attached garage (R315).

Should bedroom circuits be 15 or 20 amp?

Either is allowed. 15 A on 14 AWG is typical for bedrooms; 20 A on 12 AWG gives headroom for a home office or a window AC. The AFCI breaker rating must match.

Are tamper-resistant outlets required in bedrooms?

Yes, for all 15 and 20 A, 125 V receptacles in a dwelling (406.12), except ones more than 5.5 ft above the floor and receptacles that are part of a light fixture or appliance.
