Does an HOA have to keep reserve funds in a separate bank account?

By OurHOA · General information · Revised September 23, 2026

Whether HOA reserves need their own bank account, what the commingling rules really prohibit, who has to sign withdrawals, and how to fix a single-account setup.

Part of the HOA board handbook: treasurer and money.

Separate accounting is the rule everywhere; a separate account is the rule in fewer places

The question boards ask is about bank accounts, and the answer most statutes give is about bookkeeping. A reserve fund is a classification on the balance sheet, and a bank account is a place where cash sits. Nearly every rule on this subject requires the first and only sometimes requires the second. Our guide on the difference between an HOA reserve fund and an operating fund works through that distinction in detail. The practical consequence is that a board looking at one bank statement with one balance cannot tell whether it is complying with anything. If reserve contributions and reserve spending are tracked as their own fund in the general ledger, reconciled monthly, and reported on their own line, an association can satisfy a separate-accounting requirement while holding the cash in one place. If the books show only a single cash number and the reserve balance is whatever the treasurer says it is, the association is out of compliance no matter how many accounts it has open.

What the commingling statutes actually prohibit

Florida is the clearest and the strictest, and it splits by community type. For condominiums, Florida Statutes section 718.111(14) provides that all funds collected by an association shall be maintained separately in the association's name, that for investment purposes only reserve funds may be commingled with operating funds, that commingled operating and reserve funds shall be accounted for separately, and that a commingled account shall not at any time be less than the amount identified as reserve funds. That last clause is the one boards miss: if the combined account ever dips below the reserve balance, the association has spent reserve money on operating bills whether or not anyone meant to. The same subsection separately bars a licensed manager, or an officer, director or employee of the association, from commingling association funds with their own or with another association's. For homeowners' associations, Florida Statutes section 720.303(6) provides that reserve and operating funds shall not be commingled prior to turnover, allows the association to invest reserve funds jointly so long as the jointly invested funds are accounted for separately, and provides that reserve funds and interest accruing on them remain in the reserve account and are used only for authorized reserve expenditures unless another use is approved in advance by a majority vote at a meeting at which a quorum is present. California comes at it from the manager's side. Civil Code section 5380(b) requires a managing agent holding association funds to keep them in an account in the name of the association or in the agent's name as trustee for the association, insured by a federal agency or guaranty corporation, kept separate, distinct and apart from the agent's own funds or anyone else's, and not invested in stocks or high-risk options, with no interest inuring to the agent's benefit.

Who signs matters more than what the account is called

A separate account with one signer is weaker control than a shared account with two. California Civil Code section 5510(a) requires the signatures of at least two persons, who shall be directors, or one officer who is not a director and one who is a director, for the withdrawal of money from the association's reserve accounts. Subsection (b) then limits what the money can be spent on at all: the board shall not expend reserve funds for any purpose other than the repair, restoration, replacement or maintenance of, or litigation involving, major components the association is obligated to maintain and for which the reserve fund was established. Civil Code section 5502 adds a dollar trigger that applies to operating and reserve accounts alike. Transfers greater than the lesser of five thousand dollars or 5 percent of estimated income, for an association with 50 or fewer separate interests, or the lesser of ten thousand dollars or 5 percent of estimated income for a larger one, require prior written board approval. A board that wants real protection writes those three things into a banking resolution: two signatures on reserve withdrawals, no online transfer rights for a single person, and a named approval threshold. Then it sends the bank the resolution rather than assuming the signature card is enough.

Borrowing from reserves is a regulated act, not a bookkeeping entry

The reason a separate account is worth the trouble is that moving money out of reserves is supposed to be hard, deliberate and documented, and one account makes it easy, casual and invisible. California Civil Code section 5515 is a good template even for boards outside California. It lets a board temporarily transfer reserve funds to the operating account for short-term cash-flow requirements or other expenses, but requires notice to members that states the reasons the transfer is needed, some of the options for repayment, and whether a special assessment may be considered; requires written findings in the minutes explaining why the transfer is needed and how it will be repaid; requires the funds to be restored to the reserve fund within one year, with a documented justification if the board delays; and lets the board levy a special assessment to recover the full amount of the expended funds. None of that machinery works if nobody can say what the reserve balance was on the day the money moved. The decision to borrow is one question. This page is about the plumbing that makes the decision auditable afterward.

What a one-account setup costs you in practice

Four problems show up again and again in small self-managed communities that keep everything in one checking account. The first is quiet erosion: the reserve balance on the budget stays the same for years while the cash behind it has been paying for landscaping overruns, and nobody notices until a roof bid arrives. The second is deposit insurance. Standard federal deposit insurance covers an association's deposits at one insured bank up to the applicable limit per ownership category, and multiple accounts at the same bank are added together rather than each insured separately, so a community with real reserves needs to spread across institutions rather than across account numbers. Our guide on how an HOA should invest its reserve funds covers that math. The third is the audit or review. A reviewer who cannot trace reserve contributions from the assessment to a deposit will qualify the report, and that language follows the association into loan applications and resale packages. The fourth is the handoff. A treasurer who leaves after four years of single-account bookkeeping leaves a successor who cannot reconstruct the reserve balance from the records, and reconstructing it later usually costs more than the separate account ever would have.

Setting it up so the next board does not have to reconstruct it

Start by reading your own documents, because a declaration or set of bylaws can require a separate reserve account even where state law does not, and that requirement is enforceable on its own terms. Then check your state's condominium and planned-community acts separately, since the two often differ as they do in Florida. If you are opening an account, open it in the association's legal name under the association's own taxpayer identification number, never under a board member's Social Security number and never in a manager's name alone, and confirm the institution is federally insured. Adopt a written banking resolution that names the authorized signers, requires two of them for reserve withdrawals, and states the amount above which prior board approval is needed. Move the reserve contribution on a schedule, monthly or quarterly on the same day, as a standing transfer rather than a year-end catch-up, so the cash matches the funding plan as the year goes rather than only on December 31. Reconcile both accounts every month and put the reserve balance and the year-to-date reserve contribution in the packet for every board meeting. Keep the statements for at least as long as your records-retention rule requires, and longer if a reserve-funded project is still inside its warranty period. If the association is starting from one commingled account, do not try to rewrite history: calculate the reserve balance the funding plan says should exist, record a board resolution stating the balance, the date, and the basis for the figure, open the account, and transfer what you can with a written plan for the shortfall. An honest restatement with a dated resolution behind it is defensible. A round number nobody can explain is not.
