Decks & Porches in Conway — what to know

Rebates & incentives

Decks are not eligible for Mass Save rebates. Conway is served by Eversource, an investor-owned utility, but that has no effect on deck project costs. The South River and Poland Brook create 100-foot buffer zones under the Wetlands Protection Act. Any deck within those buffers requires a Notice of Intent with the Conway Conservation Commission before the building department will issue a permit. Conway's hilly, wooded terrain also harbors seasonal wetlands on some parcels away from the named streams. A site assessment on any naturally moist or low-lying lot is worthwhile before committing to a deck location.

Permits in Conway

The Conway Building Department issues deck permits under 780 CMR. The 51-year median home age means many existing decks were built in the late 1970s and 1980s and may predate current ledger flashing standards. Any building permit for structural deck work triggers a review of ledger attachment, flashing, guardrail height at 36 inches, and baluster spacing under 4 inches. Footings must reach 48 inches below grade for Franklin County frost protection. Rocky or sloped terrain in Conway may require helical piles on some lots. Permit processing in small Franklin County building departments runs two to four weeks.

Where a permit is required, decks & porches work in Conway is filed with the Conway Building Department; see the Conway Building Department’s contact, portal and who pulls the permit on permits.llc.

Typical project cost

Conway is in the Franklin County pricing band, below eastern MA. A new 300 to 400 square-foot pressure-treated deck runs $12,000 to $21,000 installed. Composite or PVC decking adds $5,000 to $10,000 over pressure-treated. Hillside lots with complex terrain or sloped framing can push structural costs higher. Three-season porches start around $30,000. Contractors from Greenfield and the Route 116 corridor serve most of Conway.

About Conway homes

Conway is a Franklin County town of 1,773 residents with 845 housing units and a median home age of about 51 years. The housing stock is primarily 1970s and 1980s homes on large rural lots, with some older farmhouses scattered through the landscape. Conway is a hill town with considerable elevation variation: the South River and Poland Brook run through the town before joining the Deerfield River to the north, and these stream corridors create riparian wetland areas throughout. Deerfield, Ashfield, Whately, Buckland, and Williamsburg are neighboring towns. The rural lot character means deck projects often have room for generous footprints.

Common questions — Decks & Porches in Conway

My Conway property is near the South River. Do I need Conservation Commission review for a deck?
If any part of the deck is within 100 feet of the South River or its associated wetlands, a Notice of Intent with the Conway Conservation Commission is required under the Wetlands Protection Act. The South River and Poland Brook both have riparian wetland corridors that extend the buffer in some areas.
What footing depth is required for decks in Conway?
Franklin County frost depth requires footings at 48 inches below grade. On Conway's rocky hillside lots where ledge is close to grade, helical piles to frost depth are an accepted alternative to Sonotubes.
My 1970s Conway colonial has an attached deck. What code issues might come up if I add to it?
Any structural addition requires a permit, which triggers a full code review. Ledger attachment, flashing, guardrail height at 36 inches, and baluster spacing under 4 inches are the common issues found in decks from that era.
Can I add a screened porch to my Conway farmhouse?
Yes. A building permit is required. In Conway's hilly terrain, the porch foundation needs to be engineered for sloped grade conditions in some cases. Budget $30,000 and up for a screened porch addition in this market.
Are there deck contractors who work in Conway?
Conway is served by contractors from Greenfield and the Route 116 corridor. Deerfield and Whately-based contractors also take work in Conway. Book spring and summer projects two to three months ahead given limited contractor availability in western Franklin County.
