Dennis — One Town, Three Price Tiers -- Cape Cod Bay to Nantucket Sound

What Actually Makes Dennis Different

Start with the number every generic listing site flattens into one figure: Zillow's typical-home-value index for Dennis overall is $685,768 as of June 30, 2026, up 2.5% year over year. That blended town-wide average hides a genuinely three-tiered market. On the Cape Cod Bay side and inland, the Dennis village/South Dennis area (ZIP 02638) has been trading roughly $871,000 to $958,000 by zip-level transaction data, though down about 13% year over year from a June 2025 peak near $1 million. On the Nantucket Sound side, Dennis Port's typical value is directly confirmed at $565,009 (+3.6% year over year) -- a gap of $300,000 or more between the north and south sides of the same town, likely reflecting Dennis Port's older motel-and-cottage housing stock against the more upscale bay-side villages. West Dennis and South Dennis-specific Zillow or Redfin figures could not be retrieved this research pass -- an honest gap, not an assumption that they track Dennis-village or Dennis-Port numbers -- so readers should check current listings directly for those two villages. One number worth debunking rather than repeating: East Dennis's widely-quoted "123.5% year-over-year, $1.71 million median" figure is a confirmed small-sample statistical artifact, not a real trend -- Redfin's own East Dennis data shows only 2 homes sold in the latest period versus 11 the year prior, with days on market rising from 6 to 21. A two-sale sample swinging a median by over 100% says more about sample size than about the market.

Dennis is organized into five named villages, each a distinct Census-designated place, and each with a real, different character. Dennis -- the village proper, including North Dennis -- sits on the Cape Cod Bay side and is home to the village center, Scargo Hill and its tower, and the Cape Playhouse/Cape Cinema complex; its 2020 population was 2,399. East Dennis, population 2,585, is also Cape Cod Bay-facing, centered on Sesuit Harbor, and was settled as early as the 1630s -- British stage star Gertrude Lawrence kept a summer home there from 1940. South Dennis, population 3,899 (up from 3,643 in 2010), is the town's central and inland village, home to the N.H. Wixon Innovation School and the former South Dennis rail depot, now a Cape Cod Rail Trail access point. West Dennis, population 2,304, occupies the southwestern corner on Nantucket Sound and is the most retirement-skewed village, with a median age of 61.1 and a striking 57% of its housing units recorded as vacant (seasonal/vacation use) in the 2020 Census -- a genuine "second-home town" data point that no competitor site breaks out. Dennis Port, population 3,487, is the Nantucket Sound-facing village most defined by its motel and vacation-rental corridor along Route 28, with a distinctly different, more transient character than the northern villages. All five village populations sum exactly to the town's 2020 Census total of 14,674, cross-validated against each village's own Wikipedia CDP entry.

Government runs through open Town Meeting with a five-member Select Board and a Town Administrator, Elizabeth Sullivan, confirmed directly via the town's own website. The current Select Board, per January 2026 town minutes, is Chris Lambton (Chair), Carlyn Carey (Vice Chair), Paul McCormick (Clerk), John Terrio, and Jim Plath. One live political note worth flagging rather than treating as settled: Lambton announced an October 2025 campaign for the 1st Barnstable District state representative seat, a dynamic story worth verifying for any change to his Select Board role before relying on this roster.

Population sits at 14,674 as of the 2020 Census, down modestly from a peak of roughly 15,973 in 2000. Summer and seasonal population is estimated at around 63,000 -- more than four times the year-round count, consistent with the seasonal-housing pattern documented at the village level, especially in West Dennis. (One figure worth flagging as a mismatch rather than using: a population-estimate site citing roughly 1,787 residents for "Dennis" is describing only the small Dennis-village CDP, not the full town, and should not be read as a town-wide number.)

Property tax runs the opposite direction from some Cape neighbors: the FY2026 rate is $4.29 per $1,000 of assessed value, down slightly from FY2025's $4.33, and tied for the lowest bracket on Cape Cod alongside Chatham's $3.67. Every source found lists a single figure for Dennis rather than a separate residential/commercial split, consistent with a confirmed FY2023 uniform rate of $4.67 -- treat this as a high-confidence inference that Dennis is still on a single, uniform rate, though the town's own FY2026 classification-hearing document could not be directly pulled this research pass, so it isn't a direct primary confirmation. There is no residential exemption currently in effect for FY2026: the town's own Property Tax Exemptions page lists only senior, veteran, blind, and surviving-spouse programs plus a tax-deferral option. A "Residential Exemption Overview" was presented to the Select Board in September 2025, but it does not appear to have proceeded to adoption -- present this as considered but not adopted, a live possibility the town could revisit, rather than a closed door.

Short-term and seasonal rentals run through Chapter 113 of the Dennis Code of Ordinances ("Housing Space and Use"), which requires every rental unit -- including STRs -- to register with the Dennis Health Department, post a certificate of registration specifying maximum occupancy, pay an annual registration fee set by the Select Board, certify smoke-detector compliance annually, and keep occupant and date records. Violations are tiered: $50 for a first offense, $100 for a second, $200 for a third or beyond, with each day counted as a separate offense. Operators must also register at the state level through MassTaxConnect. The combined tax stack is unusually well-documented here: a confirmed 14.45% total, drawn directly from the town's own Short-Term Rental Fact Sheet -- State Excise 5.7%, Local Option 2%, Community Impact Fee 3%, and the Cape Cod & Islands Water Protection Excise 2.75%. Dennis Port carries an additional layer of its own, reported one step removed from a primary town source via a third-party STR-compliance aggregator: a Rental Registration Certificate plus a mandatory pre-operation Safety Inspection Certificate, a registration fee reportedly rising from $250 in 2024 to $500 effective January 1, 2025, a minimum $1 million liability-insurance requirement, and an occupancy formula of two people per bedroom plus two. Treat those Dennis Port-specific fee figures as reported rather than independently re-confirmed against a town fee schedule.

Infrastructure has a real, dated, current story tied directly to Dennis Port's motel corridor: the Route 28 Dennisport-Harwich Corridor Project, a MassDOT reconstruction of Main Street/Route 28 running from Upper County Road to the Herring River Bridge at the Dennis/Harwich town line. It adds sidewalks and 5-foot bicycle shoulders, with land-takings involved; a design hearing was held in January 2023, and a further virtual hearing on November 13, 2025 covered continuous sidewalk work, drainage upgrades, and an intersection realignment at Ferry Street and Old Main Street. It's a live, dated infrastructure project touching the exact stretch of town most defined by its vacation-rental and motel stock.

Coastal risk is an area where honest gaps matter more than filled-in numbers. Dennis is one of four Cape towns still actively applying for FEMA's Community Rating System, alongside Bourne, Barnstable, and Falmouth -- meaning no CRS-based flood-insurance discount currently applies here, unlike nine other Cape towns already receiving 10-20% discounts. What is documented: V-zones and A-zones exist across town per the town's own Coastal Resources planning material; Corporation Beach and Chapin Beach on the bay side have coastal banks rising up to 40 feet; and the town has actively intervened at West Dennis's Swan Pond River with a seawall built specifically to improve tidal flushing, plus drainage improvements. No Dennis-specific hurricane damage account was found for 1938, Carol, or Bob -- stated plainly rather than assumed. The more underused honesty angle is water quality: the Bass River and Swan Pond River estuarine systems, shared with neighboring Yarmouth, are subject to a Massachusetts DEP nitrogen TMDL requiring a 47% total-nitrogen reduction, with septic systems responsible for 82% of the controllable load -- documented effects include more than 300 acres of historical eelgrass habitat lost, recurring algae blooms, periodic dissolved-oxygen crashes, and shellfishing closures in Swan Pond River.

Cultural landmarks here have genuine depth rather than generic beach-town marketing. Scargo Hill, the Mid-Cape's highest point, carries Scargo Tower -- the current cobblestone structure dates to 1901 (not the "1902" variant found in some sources), memorializing Charles Tobey (1831-1888) and Francis Bassett Tobey (1833-1913), per the tower's own plaque; an 1874 wooden predecessor burned around 1900 before the cobblestone rebuild, and the tower was gifted to the town in 1929. The Cape Playhouse, founded 1927 by Raymond Moore, is billed as the longest-running professional summer theater in the country; alumni performers include Bette Davis, who started there as an usher, alongside Gregory Peck, Humphrey Bogart, and Julie Andrews. Next door, Cape Cinema opened in 1930, designed by Alfred Easton Poor and modeled on the South Congregational Church in Centerville; its ceiling is a 6,400-square-foot Rockwell Kent mural, painted with Jo Mielziner and installed on site, conserved in 1981 by Museum of Fine Arts Boston specialists. The Cape Cod Rail Trail begins at the former South Dennis station site, a historic rail depot. Golf runs through two town-owned public courses, Dennis Pines and Dennis Highlands, commonly marketed together as "Dennis Golf." Beaches split by coastline: Corporation Beach (also called Nobscussett Beach), Chapin Beach (with vehicle access), Mayflower Beach, and Cold Storage Beach on the bay side; West Dennis Beach, Haigis Beach, Sea Street Beach, and Glendon Road Beach on the sound side. The 1855 West Dennis Light, operational until 1914, has since been restored. And the Yarmouth-Dennis Red Sox of the Cape Cod Baseball League give the town a real summer-collegiate-baseball identity.

History runs back to 1793, when Dennis was incorporated as its own town, set off from Yarmouth and named for Rev. Josiah Dennis, a resident minister. Before that, it was known as the "East Precinct" of Yarmouth, with indigenous place names -- Nobscussett, Sesuit, Quivet -- still attached to its northern sections; European settlement in the area traces to 1639 as part of Yarmouth, more than 150 years before Dennis split off. Lacking farmable land, the early economy centered on the sea: shipbuilding at Shiverick Yard flourished from the 1830s, producing clipper ships, and a salt-works industry operated roughly from the 1700s to 1888. An Italian immigrant community settled in the late 1800s in what's still locally called "Little Italy" in parts of town, reflected today in local street names. Notable past and summer residents include author Mary Higgins Clark, actress Bette Davis via the Cape Playhouse, and, in East Dennis specifically, British stage star Gertrude Lawrence and author Scott Corbett.
