A Cambridge condo building was torn down. The owners are paying for it.
This year, a nine-story, 66-unit condominium building on the Charles River in Cambridge was demolished. The city spent about $12 million to take it down and is billing the owners. The court-appointed official handling the sale of the land has warned that some owners may get nothing back.
We are not saying 3920 faces anything like this. Riverview’s main problem was how it was built in the 1960s, not a board ignoring repairs. But it shows how a routine leak repair can uncover a problem that ends a building, and who pays when that happens. Read it alongside our earlier post, Envelope horror stories: what happens when facade repairs wait.
What happened
The Riverview Condominiums at 221 Mount Auburn Street was a concrete tower built in 1963. A separate three-story, 14-unit building sits on the same lot. In 2023, engineers getting ready for roof and drainage work to fix leaks and ponding found that the tower “was not built as originally designed,” according to the city.
The condo trust hired the engineering firm SGH. It found steel reinforcement placed lower than the design called for, concrete weaker than required, and holes cut through the floor slabs that were never in the plans, all of it “widespread throughout the building.” Its analysis found a “very low (to potentially zero) safety factor” under the loads the building code requires, including snow. A court filing described by Banker & Tradesman said the rebar sat two inches lower than the 1961 drawings showed.
Timeline
- Early 2023: Leaks on the south side lead to a roof project. Engineers find cracked balconies and signs of compromised slabs.
- 2024: Engineers estimate repairs at $73.2 million, about $915,000 per unit. Residents move out to take weight off the floors. The last one leaves on Christmas Eve 2024, at their own expense.
- April 28, 2025: The trust gives the engineering report to the city’s Inspectional Services Department.
- June 27, 2025: The city orders the building removed by July 3. The trust says it has run out of ways to finance demolition.
- July 2025: A city Board of Survey finds the building “cannot be shored up or repaired” and “must be immediately razed.” Nearby streets close July 19. The City Council approves $20 million on July 23. A court confirms the city can do the work and recover the cost.
- December 17, 2025 – late February 2026: Demolition in six phases. Asbestos in joint compound, floor tiles, and popcorn ceilings could not be removed first, because the building was too unsafe to work inside. The 17 households next door at 205 Mount Auburn St. were moved out from Nov. 17 to Jan. 31.
- Early 2026: A Land Court judge appoints a commissioner to run a court-supervised sale of the property.
- Spring 2026: About 11,500 tons of debris are trucked out, most of it to an Ohio landfill that accepts asbestos. Streets reopen April 17. The city puts the cost at about $12 million.
What it cost the owners
Owners voted against the $73.2 million repair. Then the bills came anyway.
- Demolition. The city is recovering its costs “including interest and any collection fees, directly from the property owners.” Each owner is billed a share. The city recorded a lien, and anything still unpaid gets added to fall 2026 property tax bills.
- Insurance. Master condo policies typically cover things like fire and storms, but not structural defects.
- Mortgages. The land will be sold free of the 11 mortgages on it, but the court-appointed commissioner said the sale will not wipe out the debts. He wrote: “There is a possibility that certain unit owners will not receive any sale proceeds after their mortgages, real estate taxes and outstanding condo fees, where applicable, are paid.”
- Little recourse. One real estate attorney said there was “no precedent” in Massachusetts “for anything of this magnitude,” and that suing the original builders, decades later, “seems unlikely.”
At a public meeting, Cambridge’s deputy city manager said: “They were doing regular maintenance. They were doing all the right things with the building.” That is the hard part. These owners lost their homes even though the city says they kept up with maintenance.
Why this matters for owners anywhere
- Leaks are a warning, not just a nuisance. Riverview’s problems turned up during work to stop water getting in. The city’s own list of findings included “deterioration from leakage & corrosion.” Water that gets into a building reaches the structure, too. See our post on water getting in at 3920.
- Owners carry the risk. Insurance won’t step in for defects or wear. The city sends the bill to the owners. The mortgage stays even when the home is gone.
- Money in the bank matters. A Boston condo attorney told Banker & Tradesman, “A reserve might not have helped in this situation, but there are plenty of associations where it might have.” Another said refusing to raise fees to fix things is “not going to be tolerated anymore in condominiums.”
- Finding problems early is the only defense. It’s unclear whether Riverview could have been saved if the defect had been found earlier. What is clear: you can only weigh your options once you know what’s wrong. Delay makes the bill bigger, as our envelope horror stories post shows.
Questions to ask at any building
- When did a licensed engineer last evaluate the structure and the exterior? Can owners see the report? (You have a right to inspect the records.)
- What did the engineers recommend, what has been done, and when?
- Where is water getting in, and has anyone checked what it reaches behind the walls: steel, concrete, framing?
- What does the reserve study say, and how do reserves compare with the association’s debt?
- What does the master insurance policy exclude?
- Are any special assessments being discussed, or already approved?
Before you buy, get the answers in writing.
Caveat emptor.
