What's the per square foot construction cost for adding on to my home in northern NJ?

Question:

Answers:
You are probably looking at about 100 per sq ft (give or take) for a reputable contractor, and depending on the type of construction materials that you use. If you are using expensive materials such as; gold plated plumbing fixtures, tempered argon gas insulated windows, marble flooring, cedar or redwood trim and copper or stone-roofing, then the price will be significantly higher.

If you are adding on a kitchen or bathroom the price will increase considerably due to the added cost of appliances and plumbing fixtures.
