​

Why are Medford homes perfect for additions? Our capes, colonials, and ranches sit on compact lots where building up often makes more sense than building out. Homeowners call us for second-story additions that double a ranch's living space, shed and gable dormers that turn cramped upper floors into real bedrooms and baths, kitchen and family-room additions, and in-law suites for multigenerational living.

​

What does a home addition cost in Medford? Most additions run $150–$400 per square foot, with typical projects between $50,000 and $250,000. Bump-outs start around $25,000–$50,000; bedroom additions $50,000–$100,000; kitchen additions $60,000–$150,000; in-law suites $100,000–$200,000+; and full second-story additions run $300–$700+ per square foot. See our Massachusetts cost guides on the blog for full breakdowns.

​

Permits are handled for you. Every addition in Medford requires a building permit from the City of Medford Building Division, with inspections at each stage of construction. Because we're based here, we prepare the drawings, file the permit, and schedule every inspection — and zoning questions get answered before design, not after.
