Are Our Reserves Adequately Funded?
Reserve adequacy is the most consequential financial judgment an HOA board makes — and the one most likely to be made without adequate information. This guide explains what percent-funded means, how to evaluate your current position against that standard, and what actions the board should take depending on where the association stands.

What percent-funded means
Percent-funded is the ratio of the association's current reserve balance to the “fully funded balance” — what reserves should hold given how much of each component's useful life has been consumed. If a roof has a 20-year life and it's 10 years old, the fully funded contribution for that roof is 50% of its replacement cost. Sum this across all reserve components and you get the total fully funded balance.
The 70% funded threshold is widely used because it provides a meaningful cushion against the natural variation in component condition, replacement cost inflation, and the lumpy nature of capital expenditures. At 70% funded, an association has substantial reserves relative to its liability and is unlikely to need a special assessment for any single component failure.
At 40% funded, the association has a material exposure. At under 30% funded, the association is in a high-risk position where any significant capital expenditure — a major roof, a parking structure repair, an elevator overhaul — will likely require either an emergency special assessment or borrowing.
Reserve studies: what they are and when to update
A reserve study is an independent professional assessment of all common-element components: their current condition, estimated remaining useful life, and projected replacement cost. The study outputs a funding model that shows the association how much to contribute annually to maintain a target percent-funded ratio.
There are two types: a full study (on-site inspection of all components) and an update study (desk review using prior study data with a site walk for changed conditions). Most reserve professionals recommend a full study every 3 years and an update study annually in between, though California requires a full study every 3 years minimum and Nevada requires one every 3–5 years.
A study more than 5 years old is unreliable for funding decisions. Replacement costs have inflated significantly since 2020, and component conditions may have changed materially from their last inspection.

State law reference
| State | Key statute | Reserve study rule |
|---|---|---|
| California | Civil Code §5300, §5550, §5565 | Annual Budget Report must include reserve funding plan and percent-funded disclosure. Full reserve study required at least every 3 years with an annual review update. Board must disclose reserve status in resale disclosure package. |
