Apartment Building Cost by State (2026)

The U.S. baseline for a apartment building is $221/SF–$356/SF in 2026. The actual cost in your state depends on local construction labor rates. Pick a state below for a figure adjusted to that market (BLS QCEW), or see the national apartment building cost guide. The national figure comes from Gordian's RSMeans data (Q3 2026); our apartment building cost per square foot guide walks through it.
