Reserve Studies
How Often Should an HOA Update Its Reserve Study?
The standard answer across the industry: a full reserve study every 3–5 years, with an annual review in between. But the right cycle for your association depends on your state, your property's age, and what's changed since the last study.
Why Studies Go Stale So Fast
A reserve study is a snapshot. The day it's delivered, three things start drifting:
- Costs move. Construction and materials pricing can shift 5–10% in a single year — enough to throw off a 20-year projection meaningfully.
- Components age differently than predicted. A roof rated for 8 more years might show failure at 5, or sail to 11.
- Your balance changes. Actual contributions, interest earned, and any expenditures alter the funding picture annually.
That's why analysts generally treat a study's projections as reliable for about a year — and why the annual review (even a light one) matters as much as the periodic full study.
The Recommended Cycle
Every year: review the funding plan at budget time. Update the reserve balance, adjust for actual interest and expenses, and sanity-check upcoming project costs against current bids. Many associations do this internally or with a no-site-visit update from their reserve firm.
Every 3–5 years: commission a study with a site visit so an analyst can physically reassess component conditions and re-baseline life estimates. (Pricing for full studies versus updates here: How Much Does a Reserve Study Cost?)
When to Update Sooner
Move your update forward if any of these apply:
- A major project just finished — replacement resets that component's clock and your balance
- Costs spiked — periods of rapid construction inflation can quietly gut a funding plan
- The property is 25+ years old — aging communities hit replacement clusters where many components come due together
- You're planning a big project in the next 2–3 years — fresh numbers prevent funding the wrong amount
- Storm, fire, or other damage changed component conditions
What State Law Requires
Several states set legal minimums. California requires a study at least every three years with annual reviews under Davis-Stirling. Nevada works on a five-year cycle with annual updates. Florida's SIRS rules impose ten-year structural study cycles for covered condo buildings, alongside milestone inspections. Other states are silent, leaving the cycle to your governing documents and the board's fiduciary judgment — which courts generally expect to look like prudent, informed planning, i.e., a current study.
Check your state statute and your CC&Rs; whichever is stricter controls.
The Pattern That Works
Treat it like a dental schedule: a serious exam every few years, a cleaning every year. Associations that follow the 3–5 year full-study cycle with annual reviews almost never get surprised by a component failure — the surprises happen to communities running on a decade-old study.
