HOA Reserve Deficits & Special Assessments: What to Check (2026)

Key Takeaways

About 74% of U.S. homeowners associations are underfunded, the highest rate on record, according to an analysis of more than 100,000 reserve studies by Association Reserves.
A special assessment is a one-time bill that fills the gap when the reserve fund can't cover a real repair. Typical assessments run a few thousand dollars per household; complex structural projects have run into the tens of thousands.
Florida now requires condo associations to fully fund structural reserves as of January 1, 2026, following the 2021 Surfside collapse; other states are watching closely.

If you're buying a home with HOA dues, or already own one, the number that actually matters isn't the monthly HOA fee. It's whether the association's reserve fund is anywhere close to funded. An HOA reserve deficit doesn't show up on a listing, and it rarely shows up in the monthly dues either, right up until it shows up as a five-figure bill.

Quick answer

Roughly 3 out of 4 U.S. homeowners associations are underfunded relative to what a professional reserve study says they should have saved for future major repairs. When the gap between "should have saved" and "actually saved" meets a real expense, a roof, a structural repair, a paving project, the shortfall usually becomes a special assessment: an extra, often unplanned bill on top of regular dues. Before buying into any HOA or condo, ask for the reserve study and the percent-funded figure specifically, not just the account balance.

How big is the reserve funding problem, really

Association Reserves, an industry firm that has analyzed more than 100,000 reserve studies dating back to 1986, puts the current national underfunding rate at about 74%, the highest the firm has recorded. The firm considers an association funded below 30% of its recommended reserve to be critically underfunded and at the highest risk of a special assessment. Two forces are pushing the number up: elevated construction and materials costs since 2021, and sharper scrutiny of reserve practices industry-wide following the 2021 Champlain Towers South collapse in Surfside, Florida, which killed 98 people and was later tied in part to years of deferred structural repairs and underfunded reserves.

The practical result: about 30% of associations have issued a special assessment in the last five years, and another 35% expect one within the next five, per the same research. That's roughly two-thirds of associations either having already been through one or anticipating one.

What a special assessment actually costs

Special assessment amounts vary enormously by project and market, but a useful range to anchor on: a few thousand dollars per household is typical, commonly cited estimates run $2,000 to $8,000, while complex structural or roofing projects, especially in older condo buildings, have run past $15,000 per unit. A few hundred dollars is possible for a small, contained repair; tens of thousands is possible for a major structural project split across a small number of units.

What triggers one

Special assessments are usually triggered by the same handful of things: a roof or structural repair, a major paving or plumbing project, an insurance-deductible spike after a claim, a legal settlement, or a repair the reserve study flagged years earlier that the board deferred rather than funded. The less funded the reserve going in, the more likely a real, foreseeable expense turns into a surprise bill instead of a planned withdrawal.

Florida's new law is the sharpest version of a national trend

Florida passed structural reforms directly in response to Surfside. The state now requires a Structural Integrity Reserve Study (SIRS) for any condominium building three habitable stories or taller, redone at least every 10 years. Associations that existed on or before July 1, 2022 had to complete their first SIRS by December 31, 2025. The bigger change: associations can no longer vote to waive or underfund reserves for structural items, roof, load-bearing walls, waterproofing, plumbing, electrical systems, exterior painting, windows, doors, and any component whose failure could cost more than $25,000 to fix. Full funding based on the SIRS became mandatory starting January 1, 2026, according to Florida's Department of Business and Professional Regulation. Buildings must also pass structural milestone inspections at 25 years for coastal buildings or 30 years for buildings further inland.

Other states have been watching. Even outside Florida, the direction of travel across the industry is the same: waivers and underfunding are getting harder to justify quietly, and buyers and lenders are asking sharper questions about reserve health than they did five years ago.

Before you buy: what to actually ask for

The most recent reserve study or SIRS report, with its recommended balance

Not just this: The association's current bank statement alone

A calculated percent-funded figure (actual balance ÷ recommended balance)

Not just this: A dollar total with no context for whether it's enough

Board meeting minutes from the last 12-24 months

Not just this: A verbal assurance that "everything's fine"

Whether any special assessment has been proposed, voted on, or discussed

Not just this: Only what's disclosed in the listing or HOA docs packet

The trend in reserve contributions over the last few years, not just this year's

Not just this: A single year's budget in isolation

A reserve fund with a large-looking dollar balance can still be badly underfunded if the building is old, the components are expensive to replace, or the study itself is out of date. Percent-funded, not the raw number, is the figure that actually tells you something.

Our HOA affordability calculator can help you model the combined housing payment with current HOA dues, but remember that calculation only reflects today's dues, not the risk of a future special assessment layered on top. Read how much house you can actually afford alongside it, and build in some room rather than budgeting to the exact edge of what a mortgage lender will approve.

If you already own in an underfunded HOA

Push for transparency before there's an emergency to react to. Request the current reserve study, and ask the board directly for a funding plan and timeline, not just a promise to "deal with it when something breaks." If a special assessment does get proposed, ask to see the underlying cost estimate and reserve study before the vote, and ask whether the board will allow payment in installments rather than a lump sum, many associations can offer this even when the total bill is fixed.

Watch Out: Deferring a needed repair to avoid a special assessment usually makes the eventual bill larger, not smaller. Materials and labor costs tend to rise faster than reserve contributions, and a delayed structural repair can also affect building insurance and resale value in the meantime.

Boards facing a real shortfall generally have three options: a special assessment, an association loan (still ultimately repaid through dues or a future assessment), or continued deferral. None of them are free; the choice is really about who pays, when, and how predictably.

Methodology

Reserve-funding statistics in this article come from Association Reserves' analysis of more than 100,000 reserve studies conducted from 1986 through 2025, the largest dataset of its kind in the industry. Special assessment cost ranges are compiled from multiple industry and legal sources and should be treated as general ranges, not a quote for any specific property. Florida legal requirements are drawn directly from the state Department of Business and Professional Regulation's own condominium guidance and are current as of this article's publish date; verify current requirements before relying on them, since reserve legislation has been actively changing in multiple states.

Frequently Asked Questions

What is an HOA reserve deficit?

A reserve deficit is the gap between what an HOA or condo association has saved for future major repairs (roof, structure, paving, elevators, plumbing) and what it should have saved by now, based on a professional reserve study. Association Reserves, which has analyzed more than 100,000 reserve studies since 1986, estimates about 74% of U.S. associations are currently underfunded, the highest rate the firm has recorded. An association funded below 30% of its target is generally considered critically underfunded and at the highest risk of a special assessment.

What triggers a special assessment?

A special assessment is a one-time bill on top of regular HOA dues, charged when the reserve fund cannot cover a needed expense: a roof replacement, structural repair, insurance-deductible spike, legal settlement, or a repair the reserve study flagged years ago that the board deferred. The less funded the reserve, the more likely a real expense turns into a special assessment instead of being paid from savings. Typical assessments run a few thousand dollars per household; complex structural projects have run into the tens of thousands.

How do I check an HOA's reserve health before buying?

Ask for the association's most recent reserve study (or SIRS in Florida), its current reserve fund balance, and its percent-funded figure, not just its total dollar balance. A $500,000 reserve sounds large until you compare it to what the study says the association should have. Also ask directly whether any special assessment has been discussed, voted on, or is anticipated, and check board meeting minutes for the last 12-24 months for repair discussions the seller may not volunteer.

What changed with Florida's condo reserve law?

Following the 2021 Surfside condo collapse, Florida passed reforms requiring a Structural Integrity Reserve Study (SIRS) for condo buildings three stories or taller, due by December 31, 2025 for associations that existed on or before July 1, 2022, and eliminated boards' ability to waive or underfund reserves for structural items (roof, load-bearing walls, waterproofing, plumbing, electrical, and other components over $25,000). Full funding based on the SIRS became mandatory starting January 1, 2026. Buildings must also complete structural milestone inspections at 25 years (coastal) or 30 years (inland).

I already own in an underfunded HOA. What are my options?

Push for transparency first: request the current reserve study and ask the board to present a funding plan, not just react to the next emergency. Boards facing a shortfall generally choose between a special assessment, an association loan (which still gets repaid through dues or an assessment), or deferred maintenance, which usually makes the eventual bill larger. If a special assessment is proposed, ask for the underlying reserve study and cost estimate before voting, and check whether it can be paid in installments rather than as a lump sum.
