Cost to Build a House in Maryland 2026

How Much Does It Cost to Build a House in Maryland?

The average cost to build a house in Maryland in 2026 is $378,000, or $180 per square foot for a standard mid-range finish on a 2,100 sq ft home — not including land. Maryland sits above the national average, driven by DC proximity in Montgomery and Prince George's Counties.

DC suburbs vs rest of MD: A 2,100 sq ft home in Bethesda costs roughly $599,000. The same home in Baltimore costs $368,000. In Hagerstown, expect $298,000.

DC proximity labor premium	+20–35% on labor	Montgomery/Prince George's Counties — DC market labor rates
Full basement (standard MD)	$30,000–$62,000	Frost depth requires deep footings — basements standard in MD
Chesapeake Bay buffer zone	$5,000–$20,000	Critical Area restrictions near tidal waters add compliance costs

Chesapeake Bay Critical Area: Properties within 1,000 feet of tidal waters fall under Maryland's Critical Area Law, which restricts impervious surfaces, requires vegetated buffers, and can add significant design and compliance costs to new construction.
