New Construction Costs

[Rich Hupper]

I have a client with some land in middlesex county interested in building a new house. It would be a 3 or 4 bedroom colonial with a 2 car garage roughly 2500 - 2800 sf of living area. It would not need a septic.

Id like to give him some idea what it would cost per sqft if he managed it on his own verses if he hired a general contractor. 

Anyone have figures I could share?

Thank you

This is just from my experience, so it is anecdotal. 

Depends on the GC, but a variety contractors work on a 12-15%(ish) price on top of materials. So if HVAC is 15,000, the GC would charge an additional $2,250 for their management of the process. The hope of course is that the GC can get some discounts from sub contractors. Of course each contractor works differently. If the contractor has their own crews, the cost structure would look different.

Site conditions, finishes and other considerations will make the costs vary drastically. A ballpark figure is around $200 a square foot. Keep in mind, there are also architectural fees, potential zoning legal issues, city permits, etc.
