What is the average construction cost per square foot in New Jersey?

Answer 1

I am in the process of trying to figure this out as well.

Excluding the land I would feel "cost":

$100 Square is fair & accurate "cost" per "living space", each floor

$40 garage per Square foot

$15 roof per Square foot

$60 Basement per Square foot

though we have recent (Jan 18th 2008) bids as high as $205 a square (no land included, with mid-range finish, margin included) YIKES!

which is too much on a house 4600 sq feet. Still getting bids, but $200+ would push me to reluctantly GC myself and save the huge markup. Sure it may take me 2 years+ to do myself, but I save $300K not bad for a little gray hair.

I am hearing Builder margin is around 20% to builder.

I've been doing this since 1982 and those numbers are definitely a bit off of the mark for 2010.

Living space can range from $100 to $125 a square foot and up depending on finishes and what kind of mechanical systems (Plumbing, HVAC, electric) are involved. I've built some REALLY nicely upgraded/finished homes for $125 to $150 per square foot.

$40 and up for garages is ok. It depends on whether it's insulated, drywalled, painted, etc.

I don't really know what "roof" means at that price. To build a porch roof with columns and all of the new connection systems that are required its about $18 to $20 a square foot.

$26 per square foot and up is the real basement finishing price.
