Home addition cost in Maryland
Additions combine design, approvals, excavation, foundation, structure, exterior envelope and utility tie-ins. Smaller or highly serviced additions can have a higher cost per square foot.
What belongs in the number
A responsible range accounts for planning, supervision, protection, demolition, trade labor, ordinary materials, finish allowances, cleanup and the work needed to deliver a complete result.
What moves the project higher
Structural changes, relocated utilities, premium materials, custom fabrication, difficult access and concealed conditions can move a project above an early range.
From online range to proposal
Use the calculator to test feasibility. A site visit, measurements, clarified scope and selections are still needed before a contractor can prepare a project-specific proposal.
Frequently asked questions
Is this a contractor quote?
No. It is educational planning guidance. A proposal requires site conditions, measurements and a defined scope.
Why not publish one exact price?
An exact number without property and selection information creates false confidence. Ranges show realistic uncertainty.
Does location affect cost?
Yes. Logistics, local requirements and typical finish expectations can affect the planning range.
Use the numbers to make a better decision.
Explore a localized planning range first. If the project fits your goals, request a consultation with PM Home Remodel.
