Construction Cost FAQ for Maryland
Why are building costs higher in Maryland than in neighboring states?
The metro economies around Baltimore and Washington support higher wages and land prices. Environmental regulations, county permitting fees, and stormwater requirements also add cost relative to nearby states.
Do Chesapeake Bay regulations affect construction costs?
Yes. Projects near the Bay and its tributaries face critical area protections, buffer setbacks, and stormwater management requirements that add design, review, and construction cost.
How much does land cost add to building in Maryland?
A lot in the metro corridor. Premium lot prices can account for a large share of total cost, while more affordable land is available in Western Maryland and the Eastern Shore.
Are permits expensive in Maryland?
They vary by county. Densely regulated counties charge higher fees and require more review steps, including stormwater plans and impact studies, which add both fees and schedule time.
