The cost to build a deck in Cambridge ranges from $5,200 to $23,400, with most homeowners paying around $11,050. Your actual cost depends on several factors specific to your home and the Boston-Cambridge market.
Deck cost scales directly with size — a 200 sq ft deck costs roughly half of a 400 sq ft deck for the same material and height.
Pressure-treated wood is cheapest ($15–$25/sq ft), composite costs $25–$45/sq ft, and exotic hardwoods run $30–$60/sq ft installed.
Elevated decks need taller posts, more bracing, and stairs — each set of stairs adds $500–$2,000 depending on height and material.
Basic wood railings cost $20–$40/ft while cable, glass, or composite railings run $60–$150/ft installed.
Most jurisdictions require a building permit ($100–$500) and may require engineered plans for elevated decks, adding $300–$1,000 in design fees.
The Northeast tends to have higher labor costs, partly driven by stronger union presence and higher cost of living. Stricter building codes mean more inspection requirements — budget extra for permits.
Budget $112–$750 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Short construction seasons mean contractors book up fast in spring and summer. Schedule major exterior projects in late winter for best pricing and spring availability.
Handy homeowners with basic tools can handle straightforward deck construction. If your project involves the panel, new circuits, or gas lines, hire a licensed pro. DIY can save $3,863–$4,968 in labor.
