Live in South Boston
Seven in ten homes on the market here are condominiums carved out of a triple-decker or built new, which is what the fastest-changing housing market inside the city limits looks like on an assessment roll.
South Boston is a peninsula that was farmland until Boston annexed it from Dorchester on 6 March 1804, filled and built out as a working waterfront, and stayed Irish and working class for most of a century. What it is now is easier to see in the assessment file than in any description of it. Of the 11,180 one to three-family and condominium parcels in postal South Boston on the fiscal 2026 roll, 8,001 are condominiums, which is 72%, and the median condominium is assessed at $732,300, well above Dorchester, Roxbury, Allston, Brighton or Roslindale. Just over half the stock, 5,797 parcels or 52%, is owner-occupied. And the neighborhood has something no other part of Boston has in the same way: three miles of state-run beach along its own shore, with lifeguards, at the end of a walk.
A peninsula of triple-deckers that has mostly turned into condominiums
The peninsula east of the Southeast Expressway, from the Fort Point Channel and the Reserved Channel on the north around to Dorchester Bay and Pleasant Bay on the south and east, with Andrew Square and the Dorchester line at the western end. One thing to hold on to: the Seaport, which the BPDA calls South Boston Waterfront, is a separate neighborhood row with its own 2020 population of 5,579, and postal South Boston is the single ZIP code 02127 while the Seaport is 02210. The assessment figures on this page are the peninsula and not the filled land north of it. The BPDA publishes both polygons and says plainly that its neighborhood boundaries are approximations rather than the City's official lines.
South Boston was not part of Boston until 6 March 1804, when the city annexed Dorchester Neck and renamed it. That is why Dorchester Heights, the hill Washington fortified overnight in March 1776 and forced the British off, sits inside South Boston rather than in Dorchester, and why Boston still keeps 17 March as Evacuation Day. Everything after that was fill, docks and three-deckers, and for most of a century the peninsula was Irish, working class and stable enough that people described it by who lived there rather than by what it cost.
The assessment roll now describes it better than any of that does. Of the 11,180 one to three-family and condominium parcels in postal South Boston on the fiscal 2026 roll, 8,001 are condominiums, which is 72%, and the median condominium is assessed at $732,300, higher than Dorchester, Roxbury, Allston, Brighton or Roslindale. Most of those units are floors cut out of a three-decker whose median year built is 1900. Just over half the stock, 52%, is owner-occupied, which puts South Boston between the landlord markets to the west and the house neighborhoods to the south. If you want a single number for how fast this place changed, it is that one: a peninsula built as two and three-family houses is now sold, floor by floor, as apartments.
Do not confuse this with the Seaport. The filled land north of the peninsula, which the BPDA calls South Boston Waterfront and everybody else calls the Seaport, is a separate neighborhood row with its own 2020 population of 5,579, and a separate ZIP code, 02210. Postal South Boston is 02127 and nothing else, so every figure on this page is the peninsula. The two markets are within a walk of each other and they are not the same market, and a listing that says South Boston while meaning Seaport is describing a different building type, a different age and a different price.
The tax mechanic is the city's and it matters here in a specific way. Boston publishes one residential rate, $12.40 per $1,000 for fiscal 2026, then takes $351,108 of assessed value off any parcel the owner lives in, worth $4,353.74 a year. It is a flat slab, so against a $732,300 condominium it removes about a fifth of the value rather than the half it removes in Roxbury. It is still the largest single line a resident buyer here controls, and the calendar is unforgiving: own and occupy on 1 January, file by 1 April, or pay a full year at the landlord's bill. The arithmetic on both sides is on the Boston hub.
What you are really buying is the water, twice over. Three continuous miles of state beach run along Day Boulevard from Carson Beach to Castle Island, lifeguarded in summer and free to park along, which no other Boston neighborhood has in that form. The same shoreline is the reason the City rebuilt the 1931 L Street Bathhouse as the Curley Community Center in 2023 with an open basement that lets the sea in and out and removable plates on the ocean side. Ask any seller what a nor'easter does to their street, and check the flood maps before you take a garden-level unit.
- Read the reserve study and three years of association minutes before you bid
- Ask who owns the boiler and the roof, which is the recurring question in a three-decker conversion
- Confirm whether the listing means South Boston, 02127, or the Seaport, 02210
- Ask whether the seller took the residential exemption, and set your closing against 1 January and 1 April
- Check the flood maps and the storm history before you take a garden-level unit
- Parking is the second price here: an assigned space is worth real money
How South Boston got here
- 1776Washington's army fortifies Dorchester Heights overnight in early March with cannon hauled from Ticonderoga. The British evacuate Boston on 17 March, which the city still keeps as Evacuation Day.
- 1804Dorchester Neck is annexed to Boston on 6 March and becomes South Boston, the city's first annexation and the reason the Heights are not in Dorchester.
- 1917The Red Line's Dorchester extension reaches Broadway on 15 December, with Andrew following on 29 June 1918. Those two stations are still the only rapid transit on the peninsula.
- 1931The L Street Bathhouse opens on the beach. It runs as a city bathhouse and then as a community center for the next ninety years.
- 1974Court-ordered desegregation of the Boston schools begins on 12 September, and South Boston High is its focal point. The neighborhood's reputation from that decade outlived the population that made it.
- 2004The Boston Convention and Exhibition Center opens on the filled land north of the peninsula and the Silver Line Waterfront tunnel follows in December. The BPDA begins carrying that ground as a separate neighborhood, South Boston Waterfront.
- 2016The BPDA adopts PLAN: South Boston Dorchester Avenue, a corridor plan for the industrial land between Broadway and Andrew, which is where most of the new housing on the peninsula has since been proposed.
- 2023The Curley Community Center, the old L Street Bathhouse, reopens in June after a $31.2 million renovation designed around rising water: an open basement that lets the sea in and out, interior waterproofing and removable plates on the ocean side.
Carson Beach, M Street, Pleasure Bay and Castle Island
The Department of Conservation and Recreation runs the whole shoreline as one park: Carson Beach at the Columbia Point end, M Street and L Street in the middle, the Pleasure Bay loop, and Castle Island with Fort Independence on it, granite and built between 1834 and 1851. Inland, Thomas Park holds the 1902 monument on Dorchester Heights and the widest view on the peninsula, and Joe Moakley Park carries the playing fields.
What the map does not show: this is the most usable open space in the city and it is on the outside of the neighborhood. From the middle of the peninsula the beach is a ten to twenty minute walk, and Castle Island is a drive or a long one. Where you buy decides which of those you do daily.

Method: distances and drive times are computed from one representative point near Dorchester Heights, using straight-line distance multiplied by a road factor and a tiered speed model: honest ranges, not routed times. On a peninsula this long the point matters: City Point and Andrew Square are two different neighborhoods by any measure other than the polygon.
Every gym within reach
Provision here is municipal and unusually good. The Curley Community Center, the old L Street Bathhouse, is the largest public recreational facility the City runs, a quarter of a mile long with a beach attached, and it reopened in June 2023 after a $31.2 million rebuild. The City also runs centers at Tynan on Third Street and at the Condon School on D Street.
- Curley opens at 6 a.m. on weekdays, which is the point of it for commuters
- Tynan and Condon are the nearer options from the western half of the peninsula
- A converted three-decker has no building gym and no association funding one
| Facility | What it is | Drive |
|---|---|---|
| BCYF Curley Community Center open | The 1931 L Street Bathhouse on the beach, reopened in June 2023 after a $31.2 million renovation built around flooding rather than against it. | 4–7 min |
| BCYF Tynan Community Center open | The City's center on Third Street, with a gymnasium and after-school programming at municipal prices. | 3–4 min |
| BCYF Condon Community Center open | The City's center at the Condon School on D Street, at the northern end of the peninsula. | 3–5 min |
The free option is the Harborwalk along Day Boulevard, flat, continuous and open all year, from Carson Beach around Pleasure Bay to Castle Island.
No assigned school, a list and a lottery
South Boston addresses fall under Boston Public Schools, which for kindergarten through grade eight assigns no neighborhood school. It builds a list from your address, starting with every school within a mile and adding option and citywide schools until it holds roughly 10 to 14, then runs an algorithm close to a lottery over the choices you rank. Perkins, the Condon K-8 and the Perry K-8 are the three that appear on most South Boston lists, and they are spread from one end of the peninsula to the other.
| School | Board | Note |
|---|---|---|
| Perkins Elementary School | Boston Public Schools | On Burke Street. Boston assigns no neighborhood school for kindergarten through grade eight: it builds a list from your address, starting with the schools within a mile, and runs an algorithm close to a lottery over the choices you rank. |
| Condon K-8 School | Boston Public Schools | On D Street, sharing its site with a City community center, and one of the two largest schools on the peninsula. |
| Perry K-8 School | Boston Public Schools | On East Seventh Street at the City Point end, and the district school for families who buy at the far end of the peninsula. |
| Excel High School | Boston Public Schools | On G Street, in the former South Boston High building. Every Boston high school is a citywide option rather than an address assignment, so a South Boston address neither entitles you to a place here nor keeps you out of one elsewhere. |
Excel High School occupies the building that was South Boston High, the focal point of the court-ordered desegregation that began in September 1974. Every Boston high school is a citywide option now, so no South Boston address entitles a family to a place there. Run your exact address through the district's own tool rather than trusting a catchment map.
Month by month, what living here looks like
Not a highlights reel: the actual annual rhythm, including the dates residents have to remember.
- Highs near 3 °C and lows around -5 °C at Logan, with 36 cm of snow in an average January
- A declared snow emergency clears one side of most streets, and a resident permit does not exempt you
- Space savers appear in the street after a storm, and the City removes them 48 hours after the emergency ends
- Marginally the snowiest month, at 37 cm on the 1991 to 2020 normal
- Wind off the bay makes the peninsula feel colder than the inland neighborhoods at the same temperature
- The quietest month for viewings, and the easiest time to see a unit without competition
- Highs near 8 °C, with 23 cm of snow still normal for the month
- 17 March is Evacuation Day, a Suffolk County holiday, and the parade closes Broadway
- A closing after 1 January means the residential exemption waits a year
- Highs near 14 °C and only trace snow
- 1 April is the filing deadline for the residential exemption, and missing it costs the whole year
- In a converted triple-decker, ask for the reserve study and three years of association minutes before you commit
- Highs near 19 °C, and the Harborwalk along Day Boulevard comes back into use
- The busiest listing month, and the month with the most competition on an offer
- Castle Island and the Sugar Bowl loop fill up on the first warm weekend
- Highs near 25 °C, and the state beaches open with lifeguards
- Parking near the water becomes the argument it is every summer
- The best month to test whether a unit gets the sea breeze or the sun trap
- Highs near 28 °C and lows near 19 °C, though the peninsula runs a degree or two cooler on a sea breeze
- The fiscal year turns on 1 July, and the first bill of the new assessment cycle follows
- Fireworks and the Harborwalk make the first week the busiest of the year here
- Most Boston leases turn over on 1 September and the last week of August is the worst traffic of the year
- Tropical systems reach New England in August and September, usually as heavy rain rather than wind
- The narrow streets off Broadway are hard for a moving truck, so book the permit early
- Highs near 23 °C, low humidity, and the clearest stretch of the year
- Peak of the Atlantic hurricane season, and the peninsula is where a storm surge would arrive first
- The beaches stay usable well past the lifeguard season
- Highs near 17 °C, and the wettest month on the normals at 102 mm
- Heating systems get their first test, and in a conversion that means asking who owns the boiler
- King tides in the autumn are the ones the Curley renovation was designed around
- Highs near 11 °C, with the first snow normal of the season at under 2 cm
- Coastal storms push water up Day Boulevard and into Moakley Park before they reach the streets behind
- The market goes quiet, which is the argument for buying now rather than in May
- Highs near 6 °C and 23 cm of snow on the normal
- You must own and occupy on 1 January to qualify for the next year's residential exemption, so a December closing beats a February one by a full year
- Short days, and the walk to Broadway or Andrew is what you feel most
