Decks & Porches in Medway — what to know

Rebates & incentives

Decks and porches are not eligible for Mass Save rebates. Medway is in Eversource electric territory, but that is relevant only to energy-efficiency work, not deck construction.

For permitting: the Medway Building Department issues permits under 780 CMR for any attached deck or elevated structure. Given Medway's position in the Charles River watershed, the Conservation Commission under the Wetlands Protection Act has jurisdiction over projects within 100 feet of wetlands or streams. File a Request for Determination before pulling the building permit if your lot is near any water feature. Inspectors check ledger flashing, guardrail height (36 inches minimum for one- and two-family homes), and baluster spacing under 4 inches. Frost footings must extend to roughly 48 inches in Norfolk County.

Permits in Medway

The Medway Building Department handles permits under 780 CMR. Standard inspection points include ledger-board attachment and flashing, 36-inch guardrails, and baluster spacing under 4 inches. Footings must reach 48 inches below grade. Projects near the Charles River or wetland areas require a prior filing with the Medway Conservation Commission under the Wetlands Protection Act. Medway has no historic district, so no added historical review is needed for most projects.

Typical project cost

Deck and porch pricing in Medway falls within the southwestern-suburban-Norfolk-County band, below Boston metro rates but above central MA. A pressure-treated pine deck runs $15,000 to $25,000 installed; composite or PVC decking (Trex, TimberTech, Azek) runs $24,000 to $40,000. Three-season or screened porch additions to existing decks or slabs typically run $25,000 to $50,000. Structural repairs on Medway's 1970s-era decks, rotted ledgers, failing joists, often run $3,000 to $7,000 before any surface work.

About Medway homes

Medway is a compact Norfolk County suburb of 13,164 residents with 4,598 housing units and a median home age of 50 years. Most of the housing stock is single-family colonials and raised ranches built in the 1970s and 1980s on quarter-acre to half-acre lots, situated between Holliston and Franklin along the Charles River watershed.

The Charles River and its tributaries run through Medway, and the town has significant wetland acreage. Many residential lots, especially those in neighborhoods near the river or Cedar Swamp, sit within or close to the 100-foot wetland buffer. That makes Conservation Commission review a realistic possibility for deck projects in a substantial portion of town.

Common questions — Decks & Porches in Medway

My Medway yard backs up to a wetland area near Cedar Swamp. Do I need Conservation Commission approval for a deck?
Yes, if any part of the project falls within 100 feet of the wetland boundary. File a Request for Determination with the Medway Conservation Commission under the Wetlands Protection Act before applying for a building permit. The conservation review typically takes four to eight weeks and sets the sequence for everything else.
Our 1978 Medway colonial has an original deck. What should I expect when pulling a renovation permit?
Homes from that era in Norfolk County commonly have ledger boards without modern flashing, railings below 36 inches, and footings that may not reach the required 48-inch frost depth. A permit for renovation triggers a review of the full structure, and inspectors will flag anything that does not meet current 780 CMR standards.
What is the going rate for a new composite deck in Medway?
A composite deck (Trex, TimberTech, Azek) in the 300- to 500-square-foot range typically runs $24,000 to $40,000 installed in Medway, depending on height, stairs, and railing style. Pressure-treated pine is $8,000 to $15,000 less upfront but requires more ongoing maintenance in Norfolk County's wet winters.
How long does the Medway building permit process take for a deck?
For a straightforward attached deck with no wetland review needed, the Medway Building Department typically turns permits around in one to two weeks. If a Conservation Commission filing is required, add four to eight weeks for that review before the building permit can be issued.
Can I add a screened porch to my existing Medway deck?
Yes, screened porches added to an existing deck structure are a popular project in Medway. The enclosure changes the permit category (it is treated more like a room addition than a deck), so expect engineering drawings to be required and the building permit to take a bit longer than a simple deck permit.
