Is a sinking fund the same as a reserve fund?

In most HOA settings, yes, the terms are used interchangeably. Statutes typically say reserve. Always confirm how your own documents define and restrict the fund.

Can an HOA use reserve money for operating expenses?

Often only with approval and within the documents and state law. Florida condominiums, for example, require advance approval by a majority of all the total voting interests to use reserves for other purposes (section 718.112(2)(f)).

How much should an HOA keep in reserves?

There is no single number. It depends on the components, their age and replacement cost. A reserve study provides a recommended funding plan, and some states set minimum requirements.

Are reserve funds required by law?

In some states and association types, yes. Michigan and Florida condominium statutes require reserves, while other states and community types vary. Confirm your requirements with an attorney.

HOA Glossary

HOA Sinking Fund (and Reserve Fund)

A sinking fund is money an association sets aside over time to pay for a known future cost, such as replacing a roof. In HOAs the term is often used interchangeably with reserve fund, the account that holds savings for major repairs and replacements of common property, separate from the day-to-day operating budget.

Sinking fund and reserve fund

A sinking fund is a general finance idea: set aside regular contributions so a large expense does not arrive as a surprise. In community associations, the same idea is usually called a reserve fund or reserve account, and that is the term most statutes use. Some managers and communities use sinking fund as a casual synonym. When it matters, check what your documents actually call it and what it is meant to pay for.

The fund is separate from the operating account. Operating funds pay recurring bills such as landscaping, utilities and insurance. The reserve fund is for predictable but infrequent costs such as roofing, paving, painting, elevators and pool equipment.

How the amount is decided

Boards usually rely on a reserve study, which lists components, estimates their remaining life and replacement cost, and recommends a funding plan. See the glossary entry on reserve studies. The board then builds the annual contribution into the budget. A fund that is too small is a common reason communities turn to special assessments.

Examples from state law

These are examples only, and your state may differ.

Florida condominiums: the budget must include reserve accounts for capital expenditures and deferred maintenance, including roof replacement, building painting and pavement resurfacing regardless of cost, plus other items whose deferred maintenance or replacement cost exceeds $25,000 (or an inflation-adjusted figure the division sets), computed using a formula based on estimated remaining useful life and replacement cost. Reserve funds may be used only for authorized reserve expenditures unless a majority of all the total voting interests approves another use in advance. Required reserves may be pooled, with limits. For associations that must obtain a structural integrity reserve study, members cannot vote to provide no reserves or less reserves for the structural items the statute lists, for budgets adopted on or after December 31, 2024 (section 718.112(2)(f) and (g)).

California: the Davis-Stirling Act requires the board, at least once every three years, to have a reasonably competent and diligent visual inspection of accessible areas of major components done as part of a reserve study, where the statute's threshold applies. The study must identify components with less than 30 years of remaining life, estimate their remaining life and cost, and include a funding plan, and the board must review it annually (Civil Code section 5550).

Michigan condominiums: the Condominium Act states that associations of co-owners must maintain a reserve fund for major repairs and replacement of common elements and allows the administrator to set minimum standards by rule (MCL 559.205). The statute does not itself prescribe a study schedule, so the bylaws and any adopted standards matter.

Reserve fund, special assessment and loans

If reserves fall short when a project comes due, the association can raise regular assessments, levy a special assessment, borrow or defer work, to the extent its documents and state law allow. Florida's statute, for instance, permits reserves for certain structural items to be funded by regular assessments, special assessments, lines of credit or loans, with the latter three needing approval of a majority of the total voting interests. A reserve fund does not guarantee that special assessments will never be needed, because costs and component lives can change.

What owners should look for

Owners can ask for the latest reserve study, the reserve balance and the annual contribution. Buyers often ask for the same documents before closing. A healthy plan has a recent study, realistic cost assumptions and steady contributions, not a one-time catch-up.
