What is a reserve study?

A professional inventory of common area components with remaining life, replacement cost, and a funding plan that keeps the reserve solvent.

A reserve study has two halves. The physical analysis lists every component the association must eventually replace, its condition, its remaining useful life and its estimated replacement cost. The financial analysis takes the current reserve balance and produces a contribution schedule that funds those replacements as they come due.

Studies are typically refreshed on a cycle, with a full on-site inspection less often and a financial update in between, because costs and conditions move. A study left untouched for a decade is a document about a community that no longer exists.

Whether a study is mandatory, how often it must be updated, and what must be disclosed to owners varies by state — some require both the study and an annual disclosure, others require nothing at all. The act named on your state's page is the place to check.

Why it matters to a board

The study is the board's defence on funding decisions. Following it is evidence of prudence; ignoring it in writing is evidence of the opposite.

Where the answer lives

Your recorded declaration and bylaws first, then the act that governs associations in your state. Whichever is stricter is the one that binds you.
