Decks and Porches in Boston

Boston decks and porches break into a few distinct categories: rebuilt rear porches on Dorchester, Roxbury, Jamaica Plain, and South Boston triple-deckers; roof decks on brownstones in Back Bay, South End, Beacon Hill, and the Seaport; ground-level decks in single-family neighborhoods like West Roxbury, Roslindale, and Hyde Park; and condo association-approved decks where individual units have outdoor space. Each of these has different structural, permitting, and access constraints.

Tolman Pro builds and rebuilds decks and porches throughout Boston - from triple-decker rear porch tear-downs to high-end roof decks with structural reinforcement and waterproofing.

What's Different About Boston Decks and Porches

Triple-decker rear porches are the most common Boston deck project. These three-story stacked porches were original to the buildings (often 1890-1920 construction) and many have rotted, sagged, or been condemned. Rebuild involves new framing, proper footings, new stair stringers, code-compliant railings, and tying into existing building structure. Roof decks require structural engineering to verify the existing roof can carry the live load, plus waterproofing systems, drainage, and railing systems that meet ISD standards. Condo association approval is required for unit-owner decks in multi-unit buildings.

Deck and Porch Pricing in Boston

Boston pricing runs higher than surrounding towns due to logistics, permitting, and labor:

• Triple-decker rear porch rebuild (3-story): $85,000 to $245,000
• Single-level back deck (pressure-treated): $28,000 to $58,000
• Composite back deck: $48,000 to $105,000
• Roof deck (basic, with engineering): $65,000 to $175,000
• Roof deck (premium, with pavers, planters, kitchen): $145,000 to $450,000+
• Brownstone garden-level deck/patio: $42,000 to $135,000

Logistics - parking, freight elevators, neighborhood permits - add real cost to Boston work.

Permits in Boston

Boston decks and porches require ISD permits for any structural work, roof modification, or new construction. Roof decks need structural engineer letters as part of permit submission. Historic district properties (Back Bay, Beacon Hill, South End, Charlestown) require Landmarks Commission approval. Condo association approval is required for unit-owner work in multi-unit buildings. We coordinate all permitting.
