Wellesley sits 13 miles west of downtown Boston, bordered by Newton to the east, Weston to the north, Natick to the west, and Needham and Dover across the Charles River to the south. The town covers 10.49 square miles, 10.18 of it land, and counted 29,550 residents in the 2020 Census; the Census Bureau’s most recent estimate puts the population at 31,239 as of July 1, 2025, a 6.2 percent increase over the 2020 base (U.S. Census Bureau QuickFacts, Vintage 2025). It separated from Needham in 1881 and has been a railroad suburb from the start: the Boston and Albany line that became today’s Framingham/Worcester commuter rail predates the town itself. This guide is one of the AgentinBoston town guides and follows the same structure as the rest of the series: housing stock first, then transportation, market data, school structure and daily life, with every figure sourced and dated.

What kind of houses will you find in Wellesley?

Wellesley’s housing is overwhelmingly detached single-family, and most of it is old. Thirty-five percent of the town’s housing units were built before 1940 and another 38 percent between 1940 and 1979. About 18 percent has gone up since 2000, nearly all of it replacing an older house on the same lot. Colonials account for 57 percent of the single-family stock.

Those figures come from the Town of Wellesley’s Strategic Housing Plan (June 2025 draft), which draws on the American Community Survey and the Town’s own assessor’s records (Town of Wellesley, Strategic Housing Plan). The same plan documents how little the town’s housing count moves: between 2003 and 2025 the number of single-family properties rose by just 95, even though assessor’s records show more than 1,200 single-family houses built in that span. Wellesley counted 9,282 housing units in the 2020 Census, only 765 more than in 1980 (Town of Wellesley, Census and ACS data). With almost no open land left to subdivide, new construction here is replacement construction: a house comes down and a larger one goes up.

The assessor’s records describe two very different houses under one median. Across all 7,315 single-family parcels (FY2024), the median house is 2,086 square feet with nine rooms, built in 1950, on a 15,000-square-foot lot. The top quarter by assessed value has a median year built of 1991, 4,544 square feet, ten rooms and a 23,295-square-foot lot, and is 83 percent Colonial. The bottom quarter has a median year built of 1937, 1,692 square feet, seven rooms and a lot just over 10,000 square feet, with most of its value sitting in the land rather than the building. That last detail is the teardown math in one line: when the land is worth several times the structure, the structure’s days are numbered unless a buyer wants it for its own sake.

Zoning sets the frame. Five single-residence districts cover 71.3 percent of the town’s land, with minimum lot sizes of 10,000 square feet (21.6 percent of town land), 15,000 (10.5 percent), 20,000 (24.7 percent), 30,000 (3.7 percent) and 40,000 (10.8 percent). Building height is capped at 36 feet for single-family houses permitted after 1996, and maximum lot coverage runs from 15 to 25 percent depending on lot size. Parks and conservation land take another 11.8 percent of the town, and the three college campuses about 10.5 percent (Wellesley zoning district reference, August 2025).

The pre-1940 stock: 35 percent of homes

The earliest neighborhoods grew up around the three railroad stations, which is why the oldest concentrations sit in Wellesley Farms, Wellesley Hills and the streets fanning out from Wellesley Square. Wellesley Farms, Cliff Estates and Peirce Estates carry a large share of the 1900s to 1930s houses: Colonial Revivals, Tudor Revivals, Dutch Colonials and Shingle-style houses, many on lots of 20,000 square feet or more. Closer to Wellesley Square, Poets’ Corner and the blocks around Dana Hall School mix late-Victorian houses with more modest 1920s Colonials and Capes on smaller lots. In the assessor’s bottom quartile by value, Capes and houses coded simply as “Old Style” together outnumber Colonials.

Houses of this era share a construction profile that shows up in inspection reports again and again: plaster on wood lath, single-pane double-hung sash where the windows are original, fieldstone or early poured-concrete foundations, cast-iron drain lines, and, in sections that were never renovated, knob-and-tube wiring that many insurers restrict until it is replaced. Slate roofs are common on the Tudors and the larger Colonials and can outlast asphalt by decades as long as the flashing and fasteners have been kept up. Any house built before 1978 also falls under the Massachusetts Lead Law, which matters at purchase and again at renovation. A contractor’s read on what those inspection line items mean, and which ones cost real money, is in What Your Home Inspection Report Actually Means.

The 1940 to 1979 stock: 38 percent of homes

Postwar building filled in the land between the station villages. Garrison Colonials, Capes, ranches and split-levels from the 1950s and 1960s fill many of the streets that sit farther from the three stations; Garrisons and Capes each account for 11 percent of the single-family stock townwide. The construction profile is different from the prewar houses: platform framing, copper or galvanized supply lines (galvanized is usually at the end of its life by now), oil-fired boilers that were later converted to gas where mains exist, single-zone hot-water heat, little wall insulation by current standards, and 100-amp electrical services that get upgraded the year a heat pump or an EV charger arrives. Buried oil tanks from the oil-heat decades are a standard inspection question on these houses.

Only 9 percent of the town’s units date from the 1980s and 1990s, but many houses from the postwar period were expanded in those two decades and since, so a listing’s “year built” often understates how much of the structure is new. The original footprint, the addition and the connection between them can each behave differently in an inspection, and buyers get better information by asking for permit history than by reading the year on the listing sheet.

New construction and the rules that shape it: 18 percent of homes

Since 2000 the dominant form of new construction has been the teardown-and-rebuild, and about 12 percent of the town’s current stock has been built since 2010. Demolitions occur across town; the Strategic Housing Plan notes that roughly 30 percent of demolition permits over the past five years were on lots larger than half an acre. Three sets of local and state rules shape what gets built.

  • Large House Review. The Planning Board reviews any new house or addition whose total living area plus garage space (the bylaw calls it TLAG) would exceed 3,600 square feet in a 10,000-square-foot district, 4,300 in a 15,000 district, 5,900 in a 20,000 district, or 7,200 in the 30,000 and 40,000 districts. Additions that increase TLAG by more than 10 percent and push the house past its threshold are reviewed too (Wellesley Zoning Bylaw, Large House Review). One- and two-unit houses are otherwise exempt from the Town’s Major and Minor Construction Project review unless they sit in the Floodplain and Watershed Protection District, where new construction needs a special permit.
  • Historic Preservation Demolition Review. Since 2017, demolishing a building constructed on or before December 31, 1949, or removing or enclosing 50 percent or more of its exterior, requires an eligibility determination and, for eligible buildings, a Wellesley Historical Commission hearing within 45 days. A building the Commission finds “preferably preserved” faces a delay before a demolition permit can issue (Town of Wellesley, Demolition Review Bylaw).
  • The Specialized Energy Code. Wellesley adopted the Massachusetts Stretch Code in 2011 and the Municipal Opt-in Specialized Energy Code effective January 1, 2024. For new construction, that means a house using fossil fuels must be pre-wired for future electrification and must install rooftop solar, and a mixed-fuel single-family house over 4,000 square feet must be certified Zero Energy. In practice, most new Wellesley houses are now built all-electric with air-source heat pumps and a HERS rating in the low 40s or lower. The code applies to new construction, not to renovations of existing houses (Massachusetts DOER, energy code adoption by municipality).

Accessory dwelling units are a fourth factor. Under the state’s Affordable Homes Act, one ADU of up to 900 square feet or half the size of the principal dwelling, whichever is smaller, has been allowed by right in single-family zoning districts statewide since February 2, 2025, and Wellesley’s zoning lists ADUs as a by-right use in all five single-residence districts (Massachusetts EOHLC, ADU information).

Zoning, demolition review, energy code and ADU details on this page were last verified September 29, 2026 against the Town of Wellesley Zoning Bylaw, the Town’s demolition review page and the Massachusetts DOER and EOHLC sources linked above. Confirm current requirements with the Wellesley Planning Department and Building Department before designing a project.

Condos, townhouses and multi-unit housing

Detached single-family houses make up 82 percent of Wellesley’s roughly 9,400 housing units (American Community Survey, 2019 to 2023, as reported in the Town’s Strategic Housing Plan). The assessor’s FY2024 records count 7,315 single-family parcels against 666 condominium units, 91 two-family houses, 17 three-family houses and 29 apartment buildings. The condominium count has grown by 320 units since 2003 while two- and three-family properties fell by 65, a pattern of small multi-unit buildings being converted to condos or torn down.

Condos come in two forms here. Near Wellesley Square, two-unit condominiums have been built as replacement housing on former single-family lots. Larger buildings cluster in and around Wellesley Square, along the Linden Street corridor, on Route 9 and in Lower Falls, where the zoning bylaw allows multi-unit housing. The largest recent addition is The Nines at 40 William Street, a 350-unit rental building permitted under the Town’s Chapter 40R Wellesley Park overlay. Closings at two new condominium buildings (the Bristol and the Terrazza) pushed the 2024 condo median sale price to $1,787,500 from $975,000 in 2023, so condo medians in Wellesley can swing sharply with a single building’s closings. The districts that permit three or more units by right together cover only a few percent of the town’s land, which is why condo inventory is small in any given month. For the state’s MBTA Communities law, Wellesley designated its Wellesley Square Commercial, Business, Business A, Industrial and Industrial A districts as the areas where multi-family projects may be proposed as of right.

Utilities that shape ownership costs

Wellesley owns its electric utility, the Wellesley Municipal Light Plant, which sets its own rates and handles its own outages. Drinking water comes from ten Town-operated wells supplemented by an MWRA connection that can supply up to 4.2 million gallons a day; after 2021 sampling found PFAS in the four Morses Pond wells, the Town installed interim treatment there and is planning a permanent system. Wastewater flows to the MWRA system, and just over 200 properties remained on septic as of the Town’s 2022 Open Space and Recreation Plan, with local septic rules stricter than the state’s Title 5 code. The practical effect for buyers is that Title 5 inspections, a central issue in Weston, Sherborn and Dover transactions, rarely appear in a Wellesley sale. The Town also bills a monthly stormwater utility fee based on each parcel’s impervious area, which means a large new house with a wide driveway carries a higher fee than the smaller house it replaced.

How do you get around from Wellesley?

Three MBTA commuter rail stations on the Framingham/Worcester Line, Wellesley Farms, Wellesley Hills and Wellesley Square, serve the town, with weekday peak rides of 35 to 45 minutes to South Station. By car, Route 9 crosses the town east to west, Route 16 and Route 135 meet at Wellesley Square, and I-95/Route 128 exits sit on the eastern edge.

Commuter rail, by the timetable

On the weekday schedule in effect in September 2026, 17 inbound trains stop at Wellesley Square between 5:09 AM and 11:44 PM (MBTA Framingham/Worcester Line timetable). The morning trains most commuters use leave Wellesley Square at 6:51 AM and arrive at South Station at 7:32 AM (41 minutes), and at 7:38 AM arriving 8:23 AM (45 minutes); an 8:31 AM departure arrives at 9:16 AM. Wellesley Hills is three to four minutes further inbound on each of those trains and Wellesley Farms about seven, so a 6:58 AM departure from Wellesley Farms reaches South Station in 34 minutes. Back Bay comes about six minutes before South Station on every inbound train. Midday trains make every stop and take closer to 49 minutes; the 4:56 PM inbound express from Wellesley Square runs to South Station in 35 minutes. Several peak-hour express trains from Worcester skip all three Wellesley stops, so check the specific train, not just the departure time.

Wellesley’s stations are in MBTA fare Zone 3. The Wellesley Square lot, managed by the Town, has 224 spaces at $6 per day as of September 2026, with covered bike racks. Wellesley Square has mini-high platforms for level boarding but, as of the MBTA’s July 2026 notice, no accessible path between the inbound and outbound platforms; Wellesley Hills and Wellesley Farms are not accessible. All three stations are slated for accessibility improvements in the Boston Region MPO’s draft FY2026 to 2030 Transportation Improvement Program, and the MBTA has design work underway on the Wellesley stations, so timing and construction impacts are worth checking on mbta.com before relying on a specific station.

Driving

Route 9 (the Worcester Turnpike) is a divided highway through Wellesley with interchanges at Cedar Street, Weston Road and Route 16, and it connects to I-95/Route 128 at the town’s eastern end. Route 16 (Washington Street) runs from Lower Falls through Wellesley Hills to Wellesley Square, where it meets Route 135 (Central Street) at a five-way intersection. I-95/Route 128 exits serving the town are Exit 36 (Route 9) and Exit 37 (Route 16). The Massachusetts Turnpike is reached either by taking Route 128 north about two miles to the Weston interchange (Exit 123) or by following Route 16 east 4.7 miles from Wellesley Square to the West Newton interchange (Exit 125). Logan Airport is the Turnpike east to the Ted Williams Tunnel. Drive times to downtown Boston vary widely by hour, and a live map at the commute time in question is the only reliable estimate.

The Green Line’s D branch ends at Riverside station in Newton, near the Route 128 and Grove Street interchange just past the Wellesley line, with a parking garage; Woodland station, one stop closer to Boston, sits on Washington Street (Route 16) next to Newton-Wellesley Hospital. Both are options for commuters who prefer a subway connection to Kenmore, Copley and Park Street over the commuter rail’s South Station terminus.

Bus, shuttle and trails

The MetroWest Regional Transit Authority’s Route 1 bus runs between Natick and Newton with Wellesley stops at Wellesley Square, Babson College, MassBay Community College and Lower Falls, and MWRTA runs a free shuttle between the MassBay campus and Riverside station. MWRTA’s CatchConnect curb-to-curb service covers the whole town on weekdays by advance booking. For walking and cycling, the Town maintains about 2,700 acres of open space and 46 miles of trails, 28 of them marked (Town of Wellesley, Trails). The most useful for daily errands is the Brook Path, 2.3 miles of level path along Fuller Brook from Dover Road to Maugus Avenue that passes the library, Wellesley Square and several schools. The Cochituate and Sudbury aqueduct paths cross the town on level grades, and the Crosstown Trail links Morses Pond with the Weston line. The Town’s February 2025 townwide pedestrian and bicycle routes plan identifies sidewalk gaps on portions of Routes 9, 16 and 135 and on Weston Road, and notes that dedicated bike lanes exist only on portions of Washington Street and Great Plain Avenue.

What is the Wellesley housing market doing right now?

Over the twelve months ending September 29, 2026, the median single-family sale price in Wellesley was $2,354,000 across 255 closings (MLS Property Information Network). Half of those houses went under agreement within 16 days of listing, and the median price per square foot was $652. The middle half of sales closed between $1.61 million and $3.15 million.

Source: MLS Property Information Network (MLS PIN), single-family and condominium closings from September 30, 2025 through September 29, 2026, pulled September 29, 2026. Medians are calculated from the individual closings, not from listing averages. This table is refreshed quarterly.

What sold, and for how much

The 255 single-family closings break down into six price bands: 19 percent closed under $1.5 million, 21 percent between $1.5 and $2 million, 28 percent between $2 and $3 million, 16 percent between $3 and $4 million, 7 percent between $4 and $5 million, and 8 percent (21 sales) at $5 million or more, topping out at $14.75 million. That top band is why the average sale price, $2.66 million, sits more than $300,000 above the median; the average is the wrong number to anchor on in Wellesley.

The houses that sold mirror the housing stock described above. Forty percent of them were built before 1940, 27 percent between 1940 and 1979, and 28 percent since 2000, including 33 houses (13 percent of all sales) completed in 2024, 2025 or 2026. The three groups price very differently. Prewar houses sold at a median of $1.93 million for a median 2,953 square feet, or $683 per square foot. Postwar houses from 1940 to 1979 sold at a median of $1.85 million for 2,800 square feet, $674 per square foot. New construction sold at a median of $3.35 million for 5,833 square feet, $643 per square foot. The older, smaller houses carry the highest price per square foot because so much of what a buyer pays for is the lot underneath, which is the same land-versus-building arithmetic the assessor’s records show.

Days on market tell a two-speed story. The median was 16 days and 44 percent of houses went under agreement within two weeks, but 13 percent sat for more than 90 days, which pulls the average up to 42 days. Half of the 34 slowest sales were newly built houses, which as a group carried a median of 124 days on market because most are listed while still under construction, and 19 of the 34 sold for $3 million or more, where the pool of buyers is thinnest.

On the morning of September 29, 2026, 47 single-family houses were on the market in Wellesley, which works out to about 2.2 months of supply at the past year’s pace of roughly 21 closings a month. The active inventory skews high: the median asking price was $2.8 million, 22 of the 47 were asking $3 million or more, and eight were new construction. Twenty of the 47 had been listed for 90 days or longer, so the unsold houses are disproportionately the expensive ones and the ones that came to market before they were finished. Below $2 million, where 40 percent of the past year’s sales closed, only 17 houses were available.

The 54 condominium closings are a market of two halves, and the split runs along the year the building went up. Nineteen sales were in buildings completed since 2015, mainly the mid-rises at 100 Linden Street, 148 Weston Road, 16 Stearns Road and 580 Washington Street, and those units sold at a median of $1.96 million and $1,400 per square foot, with the top of the range at $3.3 million. The 1973 mid-rises on Grove Street accounted for 12 sales at a median of $1.32 million and $853 per square foot, and the 1967 townhouses at 11 Oak Street for six sales at a median of $839,000 and $716 per square foot. Taken together, the 32 units in buildings older than 1990 sold at a median of $1.08 million, and a third of all condo sales closed under $1 million. The townwide median of $1.27 million sits between the two halves and describes very few actual units, which is why the price per square foot, $803 at the median, is the more useful condo figure. Condominium inventory on the morning of September 29, 2026 was seven units (MLS PIN showed eight listings, with one unit at 16 Stearns Road carried under two listing numbers), four of them unsold units in the new building at 16 Stearns Road. That is about 1.6 months of supply at the past year’s pace of 4.5 condo closings a month, and only one of the seven was asking less than $1 million.

Two dated reference points sit behind the live figures. The Town’s Strategic Housing Plan, citing Banker & Tradesman town statistics, reports a 2024 median single-family sale price of $2,103,500 and a 2024 condominium median of $1,787,500, the latter inflated by closings at two new buildings near Wellesley Square. Assessed values are the second lens, with a known lag: Massachusetts assessments are set as of January 1 of the prior calendar year, so FY2026 values reflect market conditions on January 1, 2025. On that basis, the Town’s Board of Assessors reports the median single-family assessment rising from $1,223,000 in FY2022 to $1,751,000 in FY2026, a 43 percent increase over four fiscal years, with the total assessed value of the town’s single-family stock reaching $14.79 billion (Town of Wellesley, FY2026 Tax Classification presentation, December 2, 2025). The median FY2026 single-family tax bill is $17,808 at the $10.17 rate, before the 1 percent Community Preservation Act surcharge (Town of Wellesley, Tax Rate and Levy History). How that rate compares with neighboring towns, and why the rate alone does not predict the bill, is covered in Massachusetts Property Tax Rates by Town.

Two structural facts keep Wellesley’s inventory tight regardless of the interest-rate cycle. Owner-occupancy runs at 84 percent of occupied units (U.S. Census Bureau, American Community Survey 2020 to 2024 estimates), and the count of single-family properties grew by 95 in 22 years. New supply arrives one replacement house at a time, which is why the monthly count of active listings in Wellesley is measured in dozens, not hundreds. The Wellesley vs Needham comparison sets these figures beside the town’s nearest neighbor to the south.

Tax rate and assessment figures last verified September 29, 2026. The FY2027 rate is normally set by the Select Board in December.

How are Wellesley schools organized?

Wellesley Public Schools operates six K-5 elementary schools (Bates, Fiske, Hardy, Hunnewell, Schofield and Sprague), Wellesley Middle School for grades 6 to 8, and Wellesley High School for grades 9 to 12, plus an integrated preschool. Enrollment on October 1, 2025 was 3,832 students: 1,702 elementary, 910 middle school and 1,220 high school.

Elementary schools follow neighborhood attendance areas, and the district’s facilities changed in 2024: new Hardy and Hunnewell elementary buildings opened for the 2024-25 school year, and the Upham school closed as the district consolidated from seven elementary schools to six. The consolidation followed a long enrollment decline; DESE data cited in the Town’s Strategic Housing Plan shows K-5 enrollment falling from a peak of 2,480 in 2008 to 1,718 in 2024. District structure and enrollment figures come from the Wellesley Public Schools district at-a-glance page, which also links each year’s October 1 enrollment report. State-published data for the district and each school, including the annual DESE report cards, is available through the Massachusetts DESE school and district profiles and the district’s assessment page. Enrollment figures last verified September 29, 2026.

Two independent schools are located in town: Dana Hall School, a day and boarding school for girls in grades 5 to 12 near Wellesley Square, and Tenacre Country Day School, serving preschool through grade 6. Wellesley is also home to three institutions of higher education: Wellesley College, Babson College in the Babson Park section, and the Wellesley Hills campus of Massachusetts Bay Community College.

What is daily life like in Wellesley?

Daily life centers on three commercial districts along Washington Street and Central Street, Wellesley Square, Wellesley Hills and Lower Falls, plus the Linden Street retail corridor near Wellesley Square. Beyond the storefronts, roughly a third of the town’s land is open space, including a 100-acre pond with a town beach, and three college campuses open to the public.

Town centers

Wellesley Square, at the junction of Central Street (Route 135) and Washington Street (Route 16), is the largest of the three districts, with the Wellesley Square commuter rail station, the main branch of the Wellesley Free Library on Washington Street, and Town Hall about 0.3 miles east. Linden Street, one block north of the tracks, carries a supermarket-anchored retail center and a mix of restaurants and services. Wellesley Hills, about 1.4 miles east along Washington Street where Route 16 meets Route 9, has its own station, a branch library and a smaller cluster of shops and restaurants. Lower Falls, at the Newton line where Washington Street crosses the Charles River, is the smallest of the three and the closest to Route 128 and the Green Line. The Fells, a residential section on the north side of town near the Weston line, has the library’s third branch.

Open space and recreation

Between 33 and 40 percent of Wellesley is open space, about half of it privately held, according to the Town’s 2022 Open Space and Recreation Plan; the Town itself owns 82 conservation properties totaling more than 545 acres. Morses Pond, roughly 100 acres in the northwest corner of town between Route 135 and Route 9, has a Town beach with seasonal swimming and a 1.2-mile shoreline loop trail. Centennial Reservation, off Oak Street near the Needham line, is 80 acres with 2.5 miles of trails and a summit on Maugus Hill. The Town Forest surrounds Longfellow Pond with a 0.8-mile loop, and the North 40, 46 acres the Town bought from Wellesley College in 2014, forms part of a 113-acre open-space corridor along Morses Pond with 5.3 miles of trails and only two road crossings. Elm Bank Reservation, state-owned land in a bend of the Charles River on the town’s southwest edge, holds the Massachusetts Horticultural Society’s gardens and several of the Town’s athletic fields. A short paved path along the Charles at Wellesley Office Park near Route 128 is listed by the Town, with the Brook Path, as an accessible walking route.

The Wellesley Recreation Department runs seasonal programs out of the Warren Building on Washington Street, and the Tolles Parsons Center on Washington Street serves as the Council on Aging’s home. The Boston Marathon passes through the town every April along Route 135 and Route 16, with the course’s halfway mark at Wellesley Square.

Campuses and culture

Wellesley College’s 500-acre campus on Lake Waban is open to walkers, and its Davis Museum is free and open to the public. Babson College occupies the Babson Park section on the Needham line, and MassBay Community College sits on Oakland Street in Wellesley Hills. The Wellesley Historical Society maintains a museum and archive, and the Historical Commission’s plaque program marks documented older houses across town.

Services and governance

Wellesley is governed by a Select Board and a representative Town Meeting. The Town owns its electric utility, the Wellesley Municipal Light Plant, and its water system. Newton-Wellesley Hospital is just over the town line in Newton at the intersection of Route 16 and Route 128. Anyone weighing Wellesley against other Greater Boston communities can start with the Moving to Boston relocation guide and the relocation guide download, which covers the corridor town by town.
