Estimating method

Start from the national Class A office core-and-shell range of $250–$450/sf, then apply New York City's location cost factor. A location factor expresses how far a city's construction cost sits from the national average: multiply the baseline by the factor to localize it.

With an illustrative NYC total factor of ~1.30:

National× NYC factor (1.30)
Low$250/sf~$325/sf
Typical$350/sf~$455/sf
High$450/sf~$585/sf

What's in and out

  • In: structure, envelope, core, base-building MEP — the core-and-shell a developer delivers.
  • Out: land, soft costs, tenant fit-out ($120–$250/sf), FF&E, and contingency.

Localize any building type

The same method works for any program: take the national cost per square foot for your building type and multiply by the New York City location cost factor.

Frequently asked questions

Why does New York cost more than the national average?

New York carries above-average installation (labor) rates driven by union wage scales, plus logistics premiums for tight urban sites, hoisting, and constrained laydown. Material factors are close to national, but labor pushes the total location factor well above 1.0.

Is tenant fit-out included?

No. The shell figure is the base building. Interior tenant fit-out for offices typically adds $120–$250/sf depending on quality and program, priced separately.
