My figures at per sq foot do not include fixtures/fans/data/phone. If someone hands me some prints for a job to bid, I will just roughly tell them $2sq.ft. If I buy the fixtures, They are builder grade $35, fans w/light kits/controls $125, bathroom combo (fan, light , heat)$150, You see what usually happens is Homeowner will opt to select their own fixtures, etc. thus saving me from having an inventory, reducing overhead costs. For a 2000 sq foot home, $4000 is not a bad price for just rough in (romex, boxes, staples etc) and trim /punch out. new 200A permanent Service is $1100, 100A Temporary pole is $450, so without light fixtures , my bid is $5500, Fixtures extra! Besides, I really hate when homeowner drops in each evening, changing their minds frequently, so if they get fixtures, Im cool with that. Cans, fluorescents--- they are all the same to me, labor wise. that price is more than sufficient for romex (240 range, dryer, etc)
Oh yes, if there is fancy what nots (whirlpool tub, extra water heaters, water softeners,spas etc) Youbetcha its more.
I dont know if I see the difference of ease in the drop method compared to sq foot.
I like the input you are all giving, I see that I am much lower than you guys (per sq foot) maybe I should adjust
I have a 5000 sq foot duplex coming up. gas stove, gas water heater, gas heat.
All #12 romex, except for dryer, and that may be gas too
