How often to update a reserve study

July 13, 2026 · 4 min read

One of the most common reserve mistakes a board makes is treating the study as a one-time purchase. A board commissions a study, files it, and does not look at it again for a decade. By then the numbers describe a building that no longer exists, and the association is either overcharging owners or, more often, badly behind. A reserve study is a living document. This guide covers how often to refresh it and when to move sooner.

The general cadence

The widely accepted practice, and the requirement in a number of states, is to update a reserve study on a regular cycle rather than letting it age indefinitely. A common benchmark is an update roughly every two to three years, with a more thorough site-visit update on a longer interval.

Florida condominium and cooperative associations should treat this as a floor rather than a ceiling, because the structural integrity reserve study requirements add their own timing expectations for the structural components. Confirm your state's and your governing documents' specific interval; the point here is that "once and done" is never the right cadence.

Why studies go stale faster than boards expect

Three forces age a reserve study:

  • Cost inflation. Construction and material costs move, sometimes sharply. A roof replacement priced five years ago can be meaningfully more expensive today, and a study built on the old price understates what the association owes its future.
  • Condition changes. Components wear at different rates than projected. A roof that was supposed to last twenty years may be failing at fifteen, or a system may be holding up better than expected. Only a fresh look catches this.
  • Contribution drift. Boards change, budgets get squeezed, and reserve contributions sometimes fall behind the plan without anyone tracking it against the study. An update re-anchors the plan to reality.

Any one of these can quietly turn an adequate plan into an inadequate one. Together they compound.

When to update early

Beyond the regular cycle, several events should trigger an update regardless of where you are in the schedule:

  • A major replacement happens. After you replace a roof or an elevator, the clock on that component resets and the study should reflect it.
  • An unexpected failure or large repair. If a component fails early or a big unplanned expense hits reserves, the plan needs to absorb that.
  • A new structural inspection. In Florida, a milestone inspection that identifies structural work should feed directly into the SIRS and the reserve plan.
  • A significant change to the property. Additions, conversions, or newly assumed common elements change the component inventory.
  • A funding decision. If the board changes its contribution or takes on a reserve-funded loan, the plan should be re-run to show the effect.

The cost of waiting

A stale study does not announce itself. The building looks fine, the reserve balance shows a number, and nothing seems wrong until a large replacement lands against underfunded reserves. At that point the board's options narrow to the two owners like least: a special assessment or a loan. Regular updates are how a board keeps those from becoming the only choices.

Between formal updates

Even in the years when you are not commissioning a formal update, the board should review the study annually against the actual budget: did we contribute what the plan called for, did any component change condition, are we still on track. This costs nothing and keeps the study from drifting silently.

If your last study is more than a couple of years old, or you are not sure when it was last refreshed, an update is worth pricing out. To have a reserve study firm in your county review your current study and recommend the right update level, tell us about your association. It is free for boards.
