Special Assessments: What They Are, What They Cost, How to Spot the Risk
Updated 20 May 2026
A special assessment is the single largest financial risk of condo ownership. Most national listicles mention them as a paragraph; few quantify the magnitude, source the data, or explain how to diligence them away before signing. This page covers the dollar ranges, the post-Surfside Florida reforms that reshaped the risk landscape, how to read a reserve study, and the six red flags that almost always predict an assessment within 5 years.
The Surfside reality check
On 24 June 2021, Champlain Towers South in Surfside, Florida collapsed, killing 98 people. Investigation found years of deferred structural maintenance the HOA had not funded. In response, Florida enacted SB 4-D (2022):
- Milestone structural inspection required at building year 30 (year 25 within 3 miles of coast)
- Structural integrity reserve study required every 10 years
- Reserves for major components must be fully funded; waivers no longer allowed
Result: thousands of Florida buildings have raised HOA fees and issued large special assessments. The lesson generalises beyond Florida: any building with deferred maintenance and underfunded reserves carries the same fundamental risk; SB 4-D just forced Florida to confront it first.
The six red flags before any condo purchase
Reserve fund under 30% funded
Almost always predicts a future assessment within 5 years
Recent reserve study refused or unavailable
Either no study exists or board hiding it. Walk away or condition offer on receipt.
Major component past useful life
Roof, elevator, boiler, pool decking, or parking deck overdue. Assessment imminent.
Pending construction defect or insurance litigation
Buyer can be on hook for legal costs and any judgment.
Board minutes discuss large capital projects without funding plan
Assessment talk usually shows up in minutes 6 to 18 months before formal notice.
Multiple unit owners delinquent on dues
Reduces operating budget, increases assessment burden on paying owners.
Documents to request before any offer
- Most recent reserve study (with engineer's signature)
- Current reserve account balance (statement, not 'verbal confirmation')
- HOA budget for current and prior 2 years
- Board meeting minutes for last 12 to 24 months
- Any pending or threatened litigation (the seller's disclosure should include this; ask anyway)
- Master insurance policy declaration page (coverage limits, deductibles, exclusions)
- Delinquency report (percent of units more than 60 days late on dues)
- In Florida: milestone inspection report and SIRS (Structural Integrity Reserve Study)
