Real Cost of Living in Plymouth, MA: Homes and Taxes

How Massachusetts Property Tax Actually Works: Proposition 2½

Massachusetts towns do not simply pick a tax rate each year. Under Proposition 2½, a 1980 ballot law, the total property-tax revenue a town may collect — its levy — is capped, and that levy can grow year over year by only 2.5% plus whatever new revenue comes from newly built or improved property (new growth), unless voters approve an override at town meeting or the ballot.

Only after that levy ceiling is set does a town divide it by its total assessed value to produce a rate expressed per $1,000 of assessed value. Some Massachusetts towns split that rate into separate residential and commercial/industrial classes; Plymouth does not. The town uses a single unified rate applied to every property class, a policy choice the Select Board has actively maintained rather than shifting more of the burden onto commercial property.

Plymouth's Tax Rate: a Unified $12.55, Not a Split Rate

Per SouthShore.news reporting on the town's FY2026 rate-setting process, Plymouth's tax rate is $12.55 per $1,000 of assessed valuation — a single, unified rate covering residential, commercial, and industrial property alike, rather than the split residential-versus-commercial rates some neighboring Massachusetts cities use. The Select Board voted to keep that single-rate structure even as total residential property valuation townwide rose about 6% (roughly $1 billion) to approximately $16.5 billion.

A separate, lower-resolution figure comes from Ownwell.com: a median annual property-tax bill of $6,728 against a median home value of $530,300, working out to an effective tax rate of about 1.27% — which Ownwell itself describes as meaningfully higher than both the U.S. median (1.02%) and the Massachusetts state median (1.15%). Treat the $12.55 statutory rate and the 1.27% effective rate as two different measures rather than a contradiction: the first is the rate applied to assessed value, the second is a trailing estimate of tax paid against home value, and they will not simply convert into each other with a single multiplication.

What Plymouth Homes Actually Cost: Two Sources, No Blending

Zillow's own home-values page, reflecting a June 30, 2026 snapshot, gives an average home value (ZHVI) of $665,167, up 3.8% year over year, with a median list price of $738,650, 273 homes for sale, and homes typically going pending in around 10 days. That figure sits well below Duxbury's own $1,147,098 ZHVI, a real, defensible basis for describing Plymouth as the more affordable option on this stretch of the South Shore, in keeping with its much larger and more economically diverse population base.

Ownwell.com, drawing on a different methodology, gives a lower median home value of $530,300, alongside that $6,728 median annual tax bill and 1.27% effective rate cited above. As with this cluster's other towns, the honest approach is to treat Zillow's ZHVI and Ownwell's median-value estimate as two different metrics from two different methods rather than resolve them into one blended figure — cite whichever matches the question being asked, and name the source.

Median household income, per massachusetts-demographics.com's 2024 estimate, is $116,941, with roughly 4.4% of families reported living in poverty by the same source. That income figure relies on a single secondary aggregator rather than a direct Census Bureau fetch, so it is worth reconfirming against Census QuickFacts before using it in anything that depends on precision.

A Town the Size of a Small City: Why Neighborhood Changes the Math

Plymouth's total area is 134.0 square miles — 96.4 square miles of land and 37.5 square miles of water — a footprint Wikipedia describes as encompassing the entire western shore of Cape Cod Bay. Named areas inside that single town line include Plymouth Center (the historic downtown and harbor core), North, West, and South Plymouth, and, further south along the coast, the distinct villages of Manomet and Cedarville. The town also holds nine public beaches, led by Plymouth Beach and its barrier extension, Plymouth Long Beach, plus an interior of lakes and ponds — including Great Herring Pond — that most visitor-facing history content never mentions.

That geographic spread means the same average or median figures above can obscure very different real costs depending on where inside Plymouth a property sits. A downtown Plymouth Center property near Plymouth Rock, Pilgrim Hall Museum, and the harbor sits in a walkable, historic, commercially developed core. A Manomet or Cedarville property on or near a coastal bluff sits in an area with active, currently documented erosion risk (below). A property further inland, away from the coast, is exposed to neither the same flood/erosion cost pressure nor the same downtown-proximity premium. None of the townwide averages above should be read as applying evenly to all three situations.

Erosion's Real Price Tag in Manomet and Cedarville

Plymouth's coastal-bluff erosion is not a hypothetical future cost for every property here — it is an actively monitored, currently documented one along specific roads, principally Manomet Avenue, Manomet Point Road, and Nameloc Drive in Cedarville, per Plymouth Independent reporting. The town's own Conservation Planner, Richard Vacca, has been quoted describing the stakes bluntly: in that area, he said, it is likely that some properties might not survive a 30-year mortgage cycle. The same reporting documents specific coastal-bank-front lots where usable backyard depth has shrunk from roughly 200 feet down to as little as 10 feet from the bank edge.

Real dollar figures accompany that risk: seawall repair or construction has run $5,000 to $50,000 or more; bluff repairs, $3,000 to $30,000; engineering and permitting, another $5,000 to $15,000; and geotextile sand bags — installed in layers, each bag weighing five to seven tons — as an interim stabilization measure short of a full seawall. The same reporting documents at least two specific homes physically relocated away from eroding coastal banks, on Ellisville Road and Oak Bluff Road, with one tracked repair completed as recently as October 2022. A build agent or buyer should treat this as an ongoing, gradual problem driven by sea-level rise and storm intensification rather than the result of any single named storm.

Plymouth Long Beach — the barrier-beach extension protecting Plymouth Harbor — carries its own dated history of public spending on erosion. A confirmed FY2015 project combined a $279,080 state grant with a $162,675 local match to repair 10 severely eroded washover areas where storm waves had been overtopping the beach's stone dike; officials later credited that work with helping the beach survive severe nor'easters in March 2018. A separate, larger, and more contested 2023 nourishment project cost $2.9 million in state funding, using sand trucked in from Carver — a project one advocacy group, the Community Land & Water Coalition, has publicly criticized as an expensive, temporary fix with real environmental costs at the sand source; that critique is one group's characterization, not an independently adjudicated finding, but the underlying dollar figures are well sourced.

Schools: Solidly Mid-Pack, Not a Premium Draw

Plymouth's schools are a genuinely more modest selling point than some of this cluster's smaller, wealthier towns, and this page will not oversell them. Per Niche's current rankings, Plymouth Public Schools carry an overall grade of B, ranking #108 of 217 Massachusetts districts and #9 of 22 districts within Plymouth County. That is a meaningfully more modest result than several of this cluster's other towns, and it means Plymouth's appeal for a buyer rests more on history, harbor and coastal lifestyle, and relative affordability than on school rankings.

Plymouth is also one of just two county seats (shire towns) of Plymouth County, the other being Brockton — a real civic distinction, since most Massachusetts counties have only one shire town, though it has no direct bearing on household cost beyond the county-government services and offices it keeps local.

Transit and Zoning: Two Wrinkles That Touch Cost

Plymouth's own MBTA commuter-rail station, at Cordage Park on the Plymouth/Kingston Line, has been closed since April 2021, one of five low-ridership stations the MBTA shut down that year. A tentative mid-2021 target to reopen by July 2022 did not happen, and by 2022 MBTA officials were on record saying commuter rail was not coming back to Plymouth in the near term. As of this research, the station remains closed, with an MBTA spokesperson attributing it to ongoing operational challenges; anyone budgeting a Plymouth commute by rail should plan around driving to Route 3/3A or to Kingston's station just over the town line, not around an in-town stop reopening on any confirmed timeline.

There is a genuine, current civic wrinkle tied to that closure: reopening the Plymouth station would trigger obligations under the state's 2021 MBTA Communities Act, requiring the town to zone for 4,210 housing units near the Cordage Park station area, versus the 2,807 units required under the town's existing, station-closed zoning designation. That creates a documented incentive for the town around keeping the station closed, separate from the ridership and budget reasons the MBTA itself has cited.

Separately, Plymouth's own affordable-housing math is actively shaping what gets built and where. The town's Subsidized Housing Inventory currently sits at 8.42%, short of the state's 10% threshold under Chapter 40B, which lets developers override local zoning when a town falls below that line. A 163-unit condo project in North Plymouth, proposed by national homebuilder Pulte, was approved by the Zoning Board of Appeals on a 3-2 vote in April 2026 under that same 40B pressure — notably, all five board members personally opposed the project but felt legally constrained by the statute. The town's own stated strategy is to proactively permit 238 additional affordable units within about 14 months, targeting roughly June 2027, which combined with 168 units already in the pipeline would reach the 406-unit total Plymouth calculates it needs for 10% and long-term 40B protection. A buyer weighing new construction or future neighborhood character in North Plymouth should factor this pipeline in.

A Practical Checklist Before You Rely on Any Number Here

First, do not blend Zillow's $665,167 ZHVI and Ownwell's $530,300 median home value into one figure — they measure different things from different methodologies, and each should be cited with its source attached.

Second, Plymouth's FY2026 $12.55 unified tax rate applies townwide, but the underlying assessed value behind that rate can differ sharply between a downtown Plymouth Center property, an inland home away from the coast, and a Manomet or Cedarville property carrying active erosion exposure — get an address-specific assessment before assuming the townwide average applies to a particular lot.

Third, if a property under consideration sits in Manomet or Cedarville, or anywhere along a coastal bank, budget for the real, documented cost range this research surfaced — $5,000 to $50,000-plus for seawall work, $3,000 to $30,000 for bluff repairs, and $5,000 to $15,000 for engineering and permitting — and get a current geotechnical and flood-insurance assessment before buying, not after.

Finally, this page does not attempt to estimate Plymouth-specific grocery, utility, or general homeowners-insurance costs beyond the coastal-erosion figures above, and the MBTA station closure means rail commuting is not currently a cost factor to plan around. Confirm every number here directly with the Town of Plymouth Assessors' Office, the Massachusetts Department of Revenue's Division of Local Services, the U.S. Census Bureau, and a Massachusetts-licensed real estate agent or tax professional before relying on any of it financially. Nothing on this page is tax, legal, or financial advice.
