I need to add a receptacle outlet to an existing line. I will run the line from an existing receptacle outlet. Is it okay to locate the new outlet below an existing window?


Yes. As long as you have part of the wall under your window (your window doesn't go to the floor) then it is treated like any other wall in your house.

  • Think we need to hear from one of the NEC gurus. MY guys won't install interior receptacles under opening windows now in new construction. – shirlock homes Mar 3 '14 at 23:17
  • @shirlockhomes - I have had three houses (one mine, two I am rehabbing) pass inspection the past 4 months. All have had multiple outlets under windows. All three cities used NEC 2011. Would like to hear if something has changed. Also one of mine wouldn't have passed the 6 foot rule without doing it. What would you do with rooms with very wide windows - which is becoming a trend in my area. – DMoore Mar 3 '14 at 23:21
  • I am curious, I really don't know the answer. I've had close-in inspections fail for outlets under a window. might be local, I'm not the NEC expert, but we have a couple of guys on here that are well versed. – shirlock homes Mar 3 '14 at 23:38

    @shirlockhomes I don't think there is anything in the code that specifically says you can't put a receptacle under a window. However, I think it's common practice to avoid it where possible. The inspector might consider the area under a window a damp location, and so would require the outlet to meet those requirements. Next time you see the inspector, I'd ask him for a code reference. It may well be a local twist. – Tester101 Mar 4 '14 at 11:44

    If it is true it is definitely a local amendment. If it is then it is the first I have EVER heard this. Nothing like this is in the NEC. I also don't think it is possible for an inspector to consider this a damp location. Even then it is treated no differently than any other interior room in a home. Think about bathroom receptacles. Personally I think it is just another case of a rogue inspector making up his own rules. – Speedy Petey Mar 4 '14 at 12:52

Under widows does not appear to be a useable wall space for a receptical in The City of Calgary's current homeowners electrical wiring guidelines. However, my house in Calgary built in 1997 has several recepticals under windows.

I just realized after commenting this is a very old question I referenced NEC 2017 below but this info has not changed in decades tried to edit but two slow.

If there is a wall below the window this space is included in the distance between outlets and depending on other outlet locations one may be required under the window (think picture window) dmoore is correct that the NEC is ok with outlets under a window and may even require them.+

note NEC exhibit 210.26 shows a fixed glass panel 2' wide with an outlet (any space greater than 2' requires an outlet). 210.52.2 specifys the space measured along the floor and around corners unbroken by doorways , and similar openings...
