What is an HOA reserve study, and what does percent funded mean?
A reserve study is a professional forecast of an HOA’s major repair costs and a savings plan to pay for them. "Percent funded" compares the cash actually in the reserve to what the study says should be there — above ~70% is considered strong, 30–70% fair, and below 30% weak, the range where special assessments and dues spikes become likely.
What a reserve study is
A reserve study is the financial backbone of a healthy condo building. A specialist inventories every major shared component with a limited life — roof, elevators, boilers, siding, decks, paving, pools — estimates when each will need replacing and what it will cost, then builds a multi-decade savings plan so the money is there when the bill arrives.
In California, associations are required to review their reserves at least annually and update a full study by a professional at least every three years (Civil Code §5550). If a building can't produce a recent one, that itself is a red flag.
Percent funded, explained
The single most useful number in a reserve study is percent funded. It's simple:
Percent funded = the cash actually in the reserve ÷ what the study says should be there. A building that should have $1,000,000 saved and has $350,000 is 35% funded.
The Community Associations Institute and reserve professionals use widely-cited benchmarks:
| Percent funded | Strength | Special-assessment risk |
|---|
| 70–100% | Strong | Low — repairs handled from savings |
| 30–70% | Fair | Moderate — vulnerable to a big surprise |
| 0–30% | Weak | High — special assessments likely |
A reality check: across one large reserve firm's book of associations, only about a quarter were in the "strong" band and roughly a third were "weak." So a fair-to-weak result isn't rare — but it's exactly the risk you're pricing in.
How to actually read one
Open the study and find four things:
- The percent funded (above) and how it has trended over recent studies.
- The 30-year funding plan — does it assume steady dues, or big jumps and special assessments baked in to stay solvent?
- The biggest upcoming components — a $600,000 roof due in three years with $200,000 in the bank is a flashing light.
- The funding method — "baseline" funding only tries to avoid hitting $0 (fragile); "full" or "threshold" funding is more resilient.
Why percent funded is not the whole story
It's the best single number, not the only one. A small building can be 100% funded and still get hammered by one uninsured event; a large, well-run building at 45% with a credible catch-up plan may be fine. Watch for boards that make the number look healthy by lowballing future costs or stretching component lifespans — compare the study's cost assumptions against reality, and read the recent minutes for what the board actually says about money.
Biggest red flags: percent funded below 30%; no study in the last 3 years; a major component due soon with no cash set aside; a funding plan that only works with a special assessment already scheduled.
What you can see without the study
You won't get the reserve study until you're fairly deep into a purchase. But the reserve's health leaves a public shadow: a building that's underfunding its future tends to raise dues faster once reality hits.

Key takeaways
- A reserve study forecasts a building’s major repairs and the savings plan to pay for them; California requires an update at least every 3 years.
- "Percent funded" is actual reserve cash ÷ what the study says should be there: 70%+ strong, 30–70% fair, under 30% weak.
- Below 30% funded means special assessments are likely — treat it as a price-negotiation point, not a dealbreaker per se.
- Percent funded can be gamed; also read the funding plan, the biggest upcoming components, and recent minutes.
What is a good percent funded for an HOA?
70% or higher is considered strong and low-risk for special assessments. 30–70% is "fair" with moderate risk, and below 30% is "weak" with a high likelihood of special assessments or sharp dues increases.
Does an HOA need to be 100% funded?
No. 100% funded is ideal but uncommon and not required. Anything in the strong band (roughly 70%+) generally means the association can handle planned replacements without special assessments. The trend and the funding plan matter as much as the exact number.
How often is a reserve study required in California?
California HOAs must review reserves at least annually and have a full reserve study prepared or updated by a qualified professional at least once every three years (Civil Code §5550). A building without a recent study is itself a warning sign.
Does a low reserve mean a special assessment is coming?
Not guaranteed, but the risk rises sharply below about 30% funded — especially if a big-ticket component (roof, elevators, plumbing, balconies) is near the end of its life with no cash set aside. Read the funding plan to see whether an assessment is already scheduled.
Where do I get the reserve study?
Request it from the seller, the listing agent, or the HOA / management company as part of the resale documents, along with the budget, recent financials, and 12 months of minutes. In California these are part of standard resale disclosures.
