Home Additions in Maryland: Adding vs. Moving
A 400 sq ft home addition at $350–$450/sq ft typically costs $140,000–$180,000 — and you keep your low mortgage rate, your established neighborhood, and your kids’ current school district.
Selling and buying a larger property typically costs 8–10% of both transactions in real estate fees alone, plus refinancing at today’s higher interest rates. For most Maryland families, expanding wins on paper before we even draft the first architectural blueprint. [Source: freddiemac.com/research]

Yes, Your Addition Needs a Permit. Yes, We Handle It.
Anne Arundel County and surrounding Maryland jurisdictions require building, electrical, and structural permits for all residential additions. Unpermitted work surfaces at the worst possible moment: when you sell your home and the appraiser or buyer’s inspector requests paperwork you don’t possess.
We handle engineering drawings, submit all paperwork to aacounty.org/permits, and coordinate every mandatory county inspection under our MHIC license.
