Special assessments
Special assessments are the single largest source of financial surprise in condo and HOA ownership. They can arrive formally, as a voted board action with a disclosed amount.

They can arrive indirectly, as a dues increase that follows a reserve shortfall or insurance spike. Or they can arrive silently, implied by the gap between what an association has saved and what it needs — visible in documents years before any official announcement. A thorough document review identifies all three types.
What a special assessment is and how it differs from regular dues
A special assessment is a one-time or time-limited charge levied by the association above and beyond the regular monthly or quarterly dues. It is typically used to fund a specific cost that the regular operating budget and reserve fund cannot absorb: an emergency structural repair, an insurance deductible following a major loss event, a capital replacement project that was underfunded in the reserve, or a legal judgment against the association. Special assessments are allocated among owners — usually by unit ownership percentage as defined in the declaration, though some associations use a flat-per-unit calculation. An assessment on a $400,000 unit in a 100-unit building might run from a few hundred dollars to tens of thousands of dollars depending on the underlying cost and the building's ownership structure. Unlike regular dues, which are predictable and budgeted, a special assessment can arrive with relatively short notice and a defined payment deadline. Some associations allow payment plans; others require a lump sum.
Three types of assessment risk: formal, discussed, and implied
Not all assessment risk is visible in the resale certificate. Formally approved assessments — ones the board has voted on and notified owners about — will appear in the resale certificate or estoppel. Discussed but not yet voted assessments — ones the board has talked about in meetings, requested bids for, or authorized an engineer or attorney to evaluate — appear in the meeting minutes but not in the statutory disclosure. Implied assessments — ones that follow directly from the arithmetic of the reserve gap, an aging component reaching end of life, or an insurance deductible that exceeds the reserve fund balance — may not appear in any document explicitly, but are visible to anyone who reads the reserve study, the reserve balance, the insurance summary, and the minutes together. A document review that only reads the resale certificate will miss the second and third categories. A review that reads the full document set will surface all three.
Reading meeting minutes for warning signs
Board meeting minutes are the primary early-warning system for upcoming special assessments. Request at least 24 months of minutes and look for specific patterns. First, discussion of contractor bids or engineering reports for capital repair projects — especially if the same project appears across multiple months without a resolution. Second, reserve shortfall discussions: when a board acknowledges that the reserve fund is insufficient to cover an upcoming replacement, an assessment is often the next step. Third, deferral language: phrases like 'tabled for next meeting,' 'awaiting additional bids,' or 'referred to the finance committee' that recur across multiple meetings on the same topic often indicate a deferred decision rather than a resolved one. Fourth, insurance discussions: a carrier nonrenewal, a significant premium increase, or a coverage change can directly trigger a budget shortfall that leads to an assessment. Fifth, any mention of legal counsel being retained for a liability claim or construction defect — legal costs and potential judgments are funded through the operating budget or special assessments when they exceed coverage.
The reserve gap: how to calculate implied assessment risk
The reserve gap is the difference between what the reserve study says the association should have saved and what it has actually saved. If the reserve study shows a total obligation of $2.4 million across all components and the actual reserve balance is $310,000, the funded percentage is approximately 13 percent. That gap — $2.09 million — does not disappear. It gets funded one of four ways: higher future dues contributions, a special assessment, deferred repairs (which typically increase the eventual cost), or borrowing. For a building with a large near-term replacement (a roof, an elevator overhaul, major structural work) and a low reserve balance, the arithmetic of the gap tells you the assessment risk even before the board has discussed it. Divide the replacement cost by the number of units to get a rough per-unit exposure estimate. A $600,000 roof replacement in a 40-unit building with a $90,000 reserve fund implies a $12,750 per-unit exposure, less whatever the reserve can contribute.
The role of insurance deductibles in triggering assessments
In coastal and hurricane-exposed markets, master policy windstorm or named-storm deductibles are a major source of special assessment risk. These deductibles are typically expressed as a percentage of insured building value — commonly one to five percent. On a building insured for $15 million, a three percent windstorm deductible is $450,000. When a storm causes damage above that deductible, the association must fund the deductible amount before the insurer pays anything — and that funding almost always comes from a special assessment. Reserve funds are typically insufficient to absorb a large windstorm deductible, meaning owners receive an assessment shortly after the storm. Florida condo owners have experienced per-unit windstorm assessments in the range of $5,000 to $30,000 or more in severely impacted buildings. Understanding the master policy's windstorm deductible before closing — and sizing HO-6 loss assessment coverage accordingly — is the practical mitigation step.
How this varies by state
Florida's post-Surfside legislation has created a new category of mandatory assessment risk. The SIRS requirements effective for buildings three stories or taller at 30 or more years old require associations to fund reserves for structural integrity components at levels that cannot be waived. Associations that had historically waived or minimized reserve contributions faced a wave of dues increases and special assessments beginning in 2023 and 2024 as they worked toward compliance with the December 31, 2024 deadline. Buyers looking at older Florida condo buildings should ask specifically whether the association levied any assessment in connection with SIRS compliance, and whether additional assessments are anticipated. Texas is more permissive: there are no state-mandated reserve study or funding requirements, and assessment authority is governed primarily by the declaration and bylaws. Arizona falls in the middle: ARS 33-1260 requires reserve balance disclosure but does not mandate a study or minimum funding. In both Texas and Arizona, the absence of a state mandate means the adequacy of reserve funding is a question the buyer must evaluate independently.
Reviewer's checklist
- Resale certificate or estoppel reviewed for all formally levied and pending assessments
- Past 24 months of board meeting minutes reviewed for assessment discussions, repair bids, and deferral language
- Reserve study obtained and reserve gap calculated (balance vs. funded obligation)
- Major component replacement timeline reviewed against reserve balance for implied assessment risk
- Master insurance policy windstorm deductible identified and per-unit exposure estimated
- Insurance budget trend reviewed across past three to five years for premium pressure
- Any history of prior special assessments reviewed for pattern and purpose
- For Florida buildings 3+ stories at 30+ years old: SIRS compliance and any related assessments confirmed
- Any pending engineering reports or contractor bids referenced in minutes identified
- Operating budget reserve contribution compared to reserve study's recommended annual funding
