What the NIST Surfside Report May Mean for Your HOA’s Reserve Fund
Ninety-eight people died because a slab connection was built too thin.
Not because the connection was too old. It was too thin, from the day the concrete cured in 1981.
Federal investigators confirmed it this summer. And it matters, because the finding changes who’s responsible when a building fails – design, construction, or the board that inherited both.
On June 22, 2026, the National Institute of Standards and Technology released its technical findings on why Champlain Towers South collapsed in Surfside, Florida, on June 24, 2021. Ninety-eight residents died in one of the deadliest structural failures in U.S. history.
Notably, the report landed two days before the disaster’s fifth anniversary. For an industry that’s spent five years assuming it already knew the answer, that timing forces a second look.
Here’s what NIST found and what it means for a structural HOA reserve study – yours included, wherever your community sits – and what your board can do about it starting this week.
That gap between knowing about a problem and fixing it is exactly what HOA Start was built to close. Start your free trial today.

What Did NIST Find?
NIST’s investigators found that Champlain Towers South didn’t fail because someone forgot to fix a crack.
In the review, the investigators traced the collapse to a punching shear failure at two garage-column connections beneath the pool deck. The failure happened in early June 2021 – nearly three weeks before the tower came down.
According to the findings, the load didn’t disappear. Instead, it redistributed onto neighboring connections that were never built to carry the load.
Those neighboring connections failed one by one until the structure ran out of places to send the weight. And on June 24, 2021, it collapsed.
Investigators ruled out the theories that circulated for years: nearby construction vibration, a sinkhole, hurricane winds, an explosion, a rooftop renovation project overloading the structure. None of it held up.
In the end, the cause was structural, and it started at the beginning.
Design and Construction, Not Just Deferred Maintenance
We can see the reality of the issue in the words of NIST co-investigator Glenn Bell: the building had “severe and widespread deviations … from codes and standards of the day.”
Some slab sections carried less than half the strength the code required.
Another issue was the work of the construction crews. Investigators found reinforcing steel placed incorrectly, with fewer bars crossing the columns than the drawings specified.
Judith Mitrani-Reiser, NIST’s other co-lead, stated that “these margins against failure were too narrow from the start.” Forty years of corrosion, added weight from planters and pavers, and pool deck modifications ate away at a safety margin that was already thin the day the building opened.
- Design shortfall: pool deck and parking-slab sections that didn’t meet code strength requirements for flexural and slab-column connections, present since 1981
- Construction deviation: reinforcing steel placed out of position, with fewer bars crossing key columns than the design called for
- Added load: planters, pavers, and sand bedding on the pool deck that were never on the original drawings
- Long-term corrosion: decades of water intrusion and deterioration that narrowed an already thin safety margin

The Warning the Board Already Had
So what should HOA boards take away from these findings? It’s about more than the engineering.
Champlain Towers South commissioned its own structural report in 2018. The engineer, Morabito Consultants, found major damage to the pool deck slab, cracking and spalling throughout the parking garage, and failed waterproofing that was letting water sit against the concrete instead of draining.
The estimated repair bill: $9.1 million, with the garage and pool deck work alone running $3.8 million.
The report warned that waiting would make it worse: “failure to replace the waterproofing in the near future will cause the extent of the concrete deterioration to expand exponentially.”
Three years later, none of the concrete restoration had started. The concrete repairs – the part the 2018 report flagged as urgent – were still just a line item on a to-do list when the building came down.
Does that sound familiar?
Most boards ignore a reserve study because the number is big. The timeline feels too distant. Nothing visibly breaks – until the year it does.
What Florida Changed – and What It Means Everywhere Else
Florida didn’t wait for NIST’s final report to act. State lawmakers passed sweeping condominium safety reforms after Surfside, and two pieces matter most for any association sitting on a structure three stories or taller.
| Requirement | What It Covers | Timeline |
|---|---|---|
| Milestone inspection (coastal) | Phase 1 visual inspection by a licensed engineer or architect, buildings within 3 miles of the coastline | 25 years from certificate of occupancy, then every 10 years |
| Milestone inspection (inland) | Same inspection standard, buildings more than 3 miles from the coastline | 30 years from certificate of occupancy, then every 10 years |
| Structural Integrity Reserve Study (SIRS) | Covers roof, load-bearing systems, fireproofing, plumbing, electrical, waterproofing/exterior paint, windows and doors, plus any deferred item over $25,000 | Completed by Dec. 31, 2025; renewed at least every 10 years |
| Reserve funding | SIRS-designated reserves can no longer be waived or underfunded, regardless of a membership vote | Non-waivable for budgets adopted after Dec. 31, 2024 |

None of this is optional anymore, and none of it can be voted away. Reserves earmarked for these categories stay locked in even if the whole membership would rather spend the money elsewhere.
A top HOA management company in Florida tracking these deadlines for a client association is already ahead of this. A self-managed board needs the same discipline built into its own process.
If your association isn’t in Florida, none of these specific deadlines apply to you directly. But the discipline behind them does.
Every state has boards sitting on a reserve study nobody funded, an inspection report nobody scheduled a follow-up for, and a “we’ll get to it” that’s aging exactly like Champlain Towers South’s concrete did.
Lapsed inspections and undocumented deferred maintenance don’t just carry structural risk, either. Carriers are paying closer attention to inspection and reserve status when they price HOA insurance, and a gap in your paperwork can shrink your coverage options right when you need them most.
What Your Board Should Do This Month
You don’t need a Florida address for this list. You need a structure with a roof, a foundation, and a maintenance history – which is every HOA in the country.
- Pull your last reserve study and read the structural section first: not the pool furniture, not the clubhouse paint. The roof, the foundation, and anything load-bearing.
- Match findings to funding, line by line: if the study flagged $200,000 in structural repairs and your reserve fund shows $40,000 earmarked, that gap is your real risk, not the study itself.
- Ask what’s been done since the last study, not just what it found: a finding with no action behind it is just a document. NIST’s report should be the thing that forces the second question.
- Put every inspection, quote, and repair record in one place your whole board can see: verbal updates at a meeting don’t survive a board turnover.
- Set a follow-up date, not a follow-up intention: “we’ll revisit this” without a date on the calendar is how three years pass unnoticed.
HOA Start Keeps This From Happening on Your Watch
In the end, Champlain Towers South’s board didn’t lack information on what was happening below the surface. They had an engineer’s report with a dollar figure and a written warning.
What they lacked was a system that kept that warning in front of the people responsible for acting on it.
HOA Start gives your board a permanent home for every reserve study, inspection report, and vendor quote your community collects – searchable, dated, and visible to every board member, not just whoever answered the email in 2018.
It connects directly to the same bookkeeping for small HOAs records you’re already keeping, so reserve funding isn’t a separate spreadsheet nobody reconciles. And digital voting and communication tools mean a funding decision doesn’t die in an unread chat.

FAQ
What did NIST find caused the Surfside condo collapse?
- A punching shear failure at two garage-slab connections beneath the pool deck, roughly three weeks before the building came down
- Design flaws present since the 1981 construction, including slab sections with less than half the required strength
- Construction deviations from the design drawings, including misplaced and missing reinforcing steel
- Decades of corrosion, added surface loads, and pool deck modifications that further thinned an already narrow safety margin
Is a structural integrity reserve study required for every HOA?
- No. Florida’s SIRS and milestone inspection requirements apply specifically to condominium and cooperative buildings three habitable stories or taller
- Single-family HOAs and buildings under three stories aren’t covered by these specific laws
- The law exists because Champlain Towers South had exactly this profile: a multi-story condominium tower with shared structural components, not because every HOA needs a state-mandated study
- Every association with shared structural components – roofs, garages, clubhouses, pool decks – still carries the underlying risk the law was written to address

What happens if a Florida association doesn’t complete its SIRS or milestone inspection?
- Local building departments can issue unsafe structure notices
- Violations can carry fines running into the thousands of dollars per month
- Board members can face personal liability for noncompliance
- Insurers increasingly factor inspection and reserve status into coverage and premiums
Can a board vote to waive structural reserve funding?
- Not for SIRS-designated categories in budgets adopted after December 31, 2024, regardless of the vote count
- Reserves may pause temporarily during a declared emergency or while funding milestone inspection repairs, for up to two consecutive budget cycles
- Non-SIRS reserves may still be waived by majority vote, depending on when the budget was adopted
- Boards outside Florida can still vote to underfund structural reserves – NIST’s report is the argument for why that’s a bad idea, not just a legal one
How often should an HOA update its structural reserve study?
- Florida law requires a refresh at least every 10 years for SIRS-covered buildings
- A material finding – new cracking, a failed inspection, storm damage – should trigger an update regardless of the calendar
- Waterproofing and drainage issues age faster than most boards expect; the 2018 Champlain Towers South report warned about this specifically, three years before the collapse
- The study only protects your community if the funding and the follow-up keep pace with it
