What is a reserve fund?

Money set aside over time for the scheduled repair and replacement of major common area components.

Also called: Replacement reserves, Capital reserves

Reserves exist because roofs, roads, pools and elevators wear out on a predictable schedule and cost more than any single year's budget. Funding them monthly spreads the cost across the owners who used the component, which is both fairer and cheaper than a special assessment at the end.

Reserves are normally held separately from operating funds and are not a slush fund for operating shortfalls. Borrowing from them to cover an operating gap is restricted in several states and, where permitted, usually requires a documented repayment plan.

The right balance is not a fixed number. It comes from the reserve study: which components exist, what they cost to replace, how much life remains, and what contribution keeps the fund solvent across the full cycle.

Why it matters to a board

Under-funded reserves show up in lender questionnaires and in every sale. It is a marketability problem long before it is an engineering one.

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.
