Hi All,

I've a project of renovating an existing single family house. The scope of work is only renovating inside of the building and adding/changing nothing outside. However, the existing building doesn't have an outdoor outlet at the front entrance of the building. Should I apply NEC 210.52(E)(1) to this situation or I can leave as it was since no work will be needed for exterior?

Thanks All,
 
IMO, if the walls are being opened up in the area where the outside receptacle should be, then you should add it. Depending on the local requirements, if walls/ceilings are open, some areas require existing be brought up to current code.
 
Our building Codes note that if more than 50% of the structure is being renovated then the entire structure is required to be brought up to current Codes so, here, you would need to add the required receptacles.
 
Here, if 50% or more by floor area is renovated, the entire structure must be brought to present codes.

What Augie said. :)
 
In my experience the city inspector probably wouldn't ask for it but there are no guarantees. I agree with Little Bill that the easier it would be to do, the more prudent to just do it. And the more likely it will get called out.

These sort of 'grandfathering' questions are usually entirely up to the AHJ and not addressed in the electrical code. If there is a rule it will be in a state or local code like Dennis mentioned.

I can see how you might confuse Dennis with Augie as they are both old! :D
 
Thanks All, The renovation is just changing lighting fixture, replace old outlets with new ones and old air handler with new air handler. I think it's less than 50% of the total area!
