Operating Fund vs Reserve Fund in an HOA: Reserve Studies Explained

9 min read·October 29, 2026·Krishna Yalamanchi

How HOA operating and reserve funds differ, what a reserve study includes, funding methods, state examples and the risks of commingling.

Quick Answer

An HOA operating fund pays for the day-to-day costs of running the community, such as landscaping, utilities, insurance and management. A reserve fund is a separate savings account for big, predictable replacements, such as roofs, paving and elevators, and it is built up over years from a portion of each owner's assessment. A reserve study is the report that estimates what those replacements will cost and when, and it is the basis for how much the association should save each year.

Operating Fund vs. Reserve Fund

Both funds are paid for from owner assessments, and both belong to the association, not to any owner. They answer different questions. The operating fund answers "what does it cost to run the community this year?" The reserve fund answers "what will it cost to replace the major things we own, and are we saving enough?"

Where the line gets blurry

Repainting an entire building is a classic reserve item, while touching up a railing is maintenance. A useful test is whether the item is a major component with a long useful life that the association must maintain, and whether it is listed in the reserve study. When the board is unsure, record the reasoning in the minutes.

What a Reserve Study Is

A reserve study is a written analysis of the major components an association must repair or replace. It estimates how long each component should last, what it will cost to replace, and how much the association should set aside each year to pay for it when the time comes. It is usually prepared by a specialist who inspects the property, though who may perform it depends on state law and your documents.

Typical components of the study

California's statute offers a useful list, because it names the minimum content. Under Civil Code § 5550(b), a study must include:

  • Identification of major components the association is obligated to repair, replace, restore or maintain that have a remaining useful life of less than 30 years.
  • The probable remaining useful life of each of those components.
  • An estimate of the cost to repair, replace, restore or maintain each.
  • An estimate of the total annual contribution needed to pay for those costs, after subtracting reserve funds already on hand.
  • A reserve funding plan showing how the association intends to fund that contribution.

The same statute requires a "reasonably competent and diligent visual inspection of the accessible areas" of the major components at least once every three years, with annual review by the board, when the current replacement value of the major components is equal to or greater than one-half of the association's gross budget excluding reserves. Associations below that threshold are not covered by that three-year requirement, so check your documents and the statute's current text.

Reserve Funding Methods

A study usually shows how much the association should contribute under one or more funding approaches. The labels below are commonly used in the industry and are described here in general terms; your study will define them for your community.

  • Baseline funding: contributions are set so the reserve cash balance stays above zero. Florida's condominium statute uses this concept: the study's recommended funding schedule must be "based on a baseline funding plan that provides a reserve funding goal in which the reserve funding for each budget year is sufficient to maintain the reserve cash balance above zero." It adds that the study "may recommend other types of reserve funding schedules."
  • Full funding: contributions aim to keep the reserve balance near the amount that would be needed, based on how much of each component's life has been used. It tends to mean higher regular assessments and a lower risk of special assessments.
  • Threshold funding: contributions aim to keep the balance above a chosen minimum dollar amount or percentage that the board selects.

The tradeoff is simple. Lower funding keeps regular fees down today and increases the chance of special assessments, loans or deferred maintenance later. Higher funding spreads the cost across owners over time, which is fairer to owners who will not own the unit when the roof fails. Reserve and fee levels also affect resale conversations; see our overview of HOA fees.

Percent funded

"Percent funded" compares the cash set aside with the amount the study says should be set aside. California's Civil Code § 5565 is an example: the annual reserve summary uses "only assets held in cash or cash equivalents" and shows the cash needed, the cash set aside, the percentage funded and the deficiency per unit.

State Examples

State reserve laws range from detailed to nonexistent. These are examples from the statute text, not a complete picture of any state.

StateWhat the statute provides
California, Civil Code §§ 5510, 5515, 5550, 5565Reserve study at least every three years (visual inspection) under conditions in § 5550, reviewed annually. Withdrawals from reserve accounts require two signatures (two directors, or one director and one officer who is not a director). Reserve funds may not be spent except for repair, restoration, replacement or maintenance of major components, or litigation involving them. A temporary transfer to operating requires specific board notice, a written finding in the minutes and restoration within one year, unless delayed by a documented finding.
Florida, Statute 718.112(2)(f) and (g) (condominiums)Budget must include reserve accounts for items such as roof replacement, building painting and pavement resurfacing, plus any item over $25,000 (or the inflation-adjusted amount). Residential condominium buildings three habitable stories or higher need a structural integrity reserve study at least every 10 years. Unit-owner-controlled associations cannot vote to provide no reserves or less reserves for those items in budgets adopted on or after December 31, 2024.

For California, see California HOA Reserve Study Rules for 2026 Boards and AB 2050. For Michigan, see Michigan HOA Reserve Fund Requirements and the Michigan condo reserve study bill.

Florida's structural integrity reserve study in brief

The statute lists the items such a study must cover, including roof, structure, fireproofing, plumbing, electrical systems, waterproofing and windows. The study is based on a visual inspection and performed or verified by a licensed engineer, a licensed architect, or a certified reserve specialist or analyst. Owner-controlled associations in existence on or before July 1, 2022 must have completed it by December 31, 2025, and in no event after December 31, 2026. Within 45 days of receiving it, the association must distribute the study or a notice of availability to each owner. This area has been amended several times, so confirm the current text with counsel.

Commingling and Other Risks

Commingling means mixing reserve money with operating money so that nobody can tell which is which. It creates problems even when the board means well.

  • Unclear balances: if reserve cash is spent on routine bills, the reserve balance reported to owners may not exist. That undermines the study and the percent-funded figure.
  • Legal restrictions: many states restrict using reserves for non-reserve purposes. California limits reserve spending to major components and litigation about them and allows temporary loans to operating only with specific notice, findings and repayment within a year. Florida says reserve funds and interest "remain in the reserve account or accounts" and may be used for other purposes only with advance approval by a majority of the total voting interests, and not at all for items covered by a structural integrity reserve study in budgets adopted on or after December 31, 2024.
  • Surprise assessments: raiding reserves to avoid a fee increase delays the bill; it does not erase it. When the roof fails, the shortfall becomes a special assessment. California requires boards that borrow from reserves to restore the funds, with a special assessment if necessary, within limits stated in § 5605.

Pooling is not commingling. Florida's statute, for example, allows reserve accounts to be pooled across required components, with structural items pooled only with each other. That is one reserve account for several components, not a mix of reserves and operations.

What Boards Should Do

  • Keep operating and reserve money in separate accounts with separate ledgers, and reconcile both monthly.
  • Commission a reserve study on the schedule your state and documents require, and update it when costs or conditions change.
  • Adopt a funding plan the board can explain in one paragraph, and put the percent funded in the annual budget package.
  • Require two authorized signatures for reserve withdrawals, as California does by statute, even if your state does not.
  • Follow your statute's steps before moving money between accounts: notice, written findings, a repayment date and a vote where required.
  • Match each reserve expenditure to a study component, and keep invoices in the file.
  • Review financial oversight duties with new directors.

Frequently Asked Questions

What is the difference between an operating fund and a reserve fund in an HOA?

The operating fund pays recurring expenses like utilities, insurance, landscaping and management. The reserve fund is savings for major, infrequent replacements like roofs and paving. They should be tracked separately, even when both are funded by the same assessment.

What is an HOA reserve study?

It is a report that lists the major components the association must maintain, estimates each one's remaining life and replacement cost, and recommends how much to save each year. Some states, such as California and Florida, require studies by statute under conditions described above.

How often should an HOA have a reserve study?

Your state law and documents set the minimum. California's Civil Code § 5550, for example, requires a visual inspection study at least every three years for associations meeting its threshold, with annual board review. Florida requires a structural integrity reserve study at least every 10 years for covered condominium buildings. Many boards update more often when costs change.

Can an HOA use reserve funds for operating expenses?

Only as your law and documents allow. California permits a temporary transfer to the operating fund with specific notice, a written finding and repayment within one year, unless delayed by a documented finding. Florida generally requires advance approval of a majority of the total voting interests, with stricter limits for structural integrity reserve items. In other states the rules differ.

What does "percent funded" mean?

It compares the amount actually set aside with the amount the reserve study says should be set aside at that time. A low percentage generally indicates a greater chance of special assessments, but the right target depends on the study, the funding plan and the board's policy.

Are reserve funds required in every state?

No. Some states require reserve studies or reserve budgeting, and many leave it to the governing documents. Ask whether your community has a plan. See condo special assessments for what happens when it does not.
