Cost to Build a 1,500 sq ft Home in New Jersey (2026)
A 1,500 sq ft two-story home in New Jersey costs about $353,628 to build at mid-range quality — $236/sq ft, land excluded. The median new home in the Northeast is 2,459 sq ft, so this build is 39% smaller than the regional median.
Is 1,500 sq ft a normal size for New Jersey?
17% of new homes completed in the Northeast fall in the 1,400–1,799 sq ft range that a 1,500 sq ft build sits in, against 23% for the most common bracket (2,400–2,999 sq ft).
The Census Bureau measures every new single-family home completed in the country. In the Northeast — the region New Jersey sits in — the median came in at 2,459 sq ft and the average at 2,644 sq ft. A 1,500 sq ft build is therefore 39% smaller than the regional median. Homes this much below the median are usually starter homes, downsizes, or accessory dwelling units rather than typical family builds, which matters because fixed costs — the kitchen, the mechanicals, the permit — do not shrink proportionally with floor area.
