CostYour condo corporation announces a major repair — a roof, an underground garage, building envelope work — and the reserve fund doesn't have enough saved to cover it, so owners are billed directly for the shortfall as a special assessment.
$3,000,000 repair, 100-unit building, reserve fund shortfall
| Total repair cost | $3,000,000 |
| Available reserve fund | $1,000,000 |
| Shortfall to be specially assessed | $2,000,000 |
| Your unit's share (assuming equal 1% ownership) | $20,000 |
What usually happens
Every condo corporation maintains a reserve fund, funded by a portion of monthly condo fees, specifically to pay for major future repairs — roofs, elevators, building envelopes, parking structures — without needing to bill owners directly. When an unexpected or larger-than-planned repair comes up and the reserve fund can't cover it, the board issues a special assessment: a one-time bill split among owners, typically proportional to each unit's ownership percentage (often tied to unit size), due within a set window that's sometimes as short as 30 to 90 days.
What you can do about it
- Check if payment plans are offered — some corporations allow the assessment to be paid over several months rather than as one lump sum, though this isn't guaranteed.
- Review the reserve fund study before buying any condo — this is the single best way to avoid an assessment surprise as a buyer, since a poorly funded reserve is a visible warning sign before you own the unit, not after.
- Ask whether the assessment is a one-time event or part of an ongoing pattern — a corporation with a history of repeated special assessments has a structural reserve funding problem worth factoring into your decision to stay or sell.
- Budget an emergency fund specifically for this possibility — even a well-run building can face one, since not every repair can be predicted years in advance.
Who to ask
If you're buying, ask your real estate lawyer to review the status certificate and reserve fund study specifically for any planned or discussed future assessments before you close. If you already own and face an assessment, ask the property management company directly about payment plan options and the engineering report behind the repair scope, since assessment amounts are sometimes negotiable or phaseable once the board sees genuine hardship cases.
