Electrical Wiring in the Home/Wiring for carport ceiling


My home has a carport built into the structure...the second floor extends over the carport, with 2 bedrooms and a bath above the carport area.  The carport is open on 3 sides.  The carport ceiling is 5/8" exterior grade gyp board.  We are replacing the ceiling and one thing I would like to do is add some lighting in the carport - some flush-mount fixtures.  I would run the wiring to the ceiling boxes inside the ceiling, along the joists, .

I would assume that, since the carport ceiling is entirely sealed up, that I DO NOT need to run wiring in conduit, but could use standard house wire.  I've taken a cursory look at ICC and NEC but haven't spotted anything that describes this situation. (Flush mount fixtures rated for damp service, of course...)

Any thoughts?

Hello Michael,
My name is Robert and ill be helping you today and in response to your question, YES you can run wire w/o being in pipe and allow me to recommend using romex althow the wire will in fact be protected from the elements the steel on the bx will eventually rust that being said as far as the lighting goes its not the actual "can/highhat" that would be suitable for wet locations in actuality its the trim and it would be the same one like those used in showers but i see no need for them what i will recommend is "No Ox" or "Ox-Guard" which will prevent seizing corrosion and rust from moisture and humidity also it will making bulb changing a breeze i took the liberty of adding a picture it can be purchased at your local home depot and it just gets a little bit brushed around the light bulb base IT DOES WONDERS.Well i hope i was able to answer your question should you have any other questions or concerns please feel free to ask and please take a moment and fill out the survey for me thank you
