California HOA Reserve Studies and the Reserve Fund: What Owners Must Know

The annual budget report arrives. The reserve-funding percentage is 23 percent. You have no idea what that number means, whether it is good or bad, or what happens to you if it stays there. Meanwhile the roof is ten years older than it was when you moved in.

The reserve fund is the single best predictor of whether your HOA will hit you with a surprise special assessment in the next five years. California law requires the HOA to study its reserves on a schedule and to disclose the results to every owner. Reading the reserve study is the closest thing owners get to reading their association’s future.

This article is about the savings side: the reserve fund and the reserve study that tells the board how much to put in it.

What a Reserve Fund Is

The reserve fund is the association’s savings account for major repairs and replacements of common-area components. It funds the new roof, the repaved driveways, the elevator rebuild, the plumbing replacement. These are one-time, large-ticket items that arrive on predictable but multi-decade schedules.

The reserve fund is not the operating fund. The operating fund pays day-to-day expenses: landscaping, utilities, management. The reserve fund exists to spread the cost of major replacements across time so that owners pay for them gradually rather than in a single catastrophic special assessment.

Under Civil Code §5510(b), reserve account funds are restricted to the repair, restoration, replacement, or maintenance of major components the association is obligated to maintain and for which the reserve fund was established, or to litigation involving that repair, restoration, replacement, or maintenance. The board cannot use reserves to cover operating shortfalls, except by a temporary transfer under strict rules (§5515). The board must give notice, in the board meeting notice, that it intends to consider the transfer, stating the reasons the transfer is needed, some of the options for repayment, and whether a special assessment may be considered (§4920, §5515(a) and (b)). The board must record a written finding in its minutes explaining why the transfer is needed and when and how the money will be repaid (§5515(c)). The board must restore the money within one year of the transfer, unless the board, after giving the same notice, makes a finding supported by documentation that a temporary delay is in the best interests of the community (§5515(d)). A separate transfer-approval rule requires prior written board approval for any transfer out of the reserve or operating accounts unless the amount is less than the lesser of $5,000 or 5 percent of the estimated income in the annual operating budget (associations with 50 or fewer separate interests) or the lesser of $10,000 or 5 percent (51 or more) (§5502(a)). Separately, §5510(a) requires two signatures for every withdrawal from the reserve accounts.

The Reserve Study: What the Law Requires

Civil Code §5550 requires the board to have a reserve study done of the components the association is obligated to maintain, where the current replacement value of those components is at least half the association’s gross budget, not counting reserves. The study must be based on a reasonably competent and diligent visual inspection of the accessible areas of those components, performed at least once every three years (§5550(a)). The board must then review the study annually, or cause it to be reviewed, and consider and implement any necessary adjustments to its analysis of the reserve account requirements. The Act does not list what counts as a “major component.” The test is practical: anything the association is obligated to repair, replace, restore, or maintain that will wear out within 30 years (§5550(b)(1)). In a typical condominium building that means the roof, exterior paint and stucco, balconies and decks, the elevator, the boiler and other shared heating and cooling equipment, the plumbing and sewer lines, the entrance hall and corridor carpets and paint, exterior lighting, the garage gate, paving and walkways, fences, and the pool and its equipment. The Act adds one thing to that list by name: gas, water, and electrical service, to the extent the association is responsible for repairing or replacing those lines (§5550(c), §4775).

Civil Code §5550(b) dictates what the study has to contain. The five required elements are:

1. An identification of the major components the association is obligated to repair, replace, restore, or maintain, and that have a remaining useful life of less than 30 years
2. An identification of the probable remaining useful life of those components as of the date of the study
3. An estimate of the cost of repair, replacement, restoration, or maintenance of each component
4. An estimate of the total annual contribution necessary to defray the cost to repair, replace, restore, or maintain those components during and at the end of their useful life, after subtracting total reserve funds as of the date of the study
5. A reserve funding plan indicating how the association plans to fund the annual contribution identified in the prior element to meet its obligation for the repair and replacement of all major components with an expected remaining life of 30 years or less, not including those components that the board has determined will not be replaced or repaired

Taken together, the first four elements feed into the fifth, the reserve funding plan: how much the association must set aside each year to be able to pay for each component when it needs replacement. The funding plan feeds directly into regular or special assessments, through a schedule of any changes needed to fund it (§5560(a)).

Condominium projects have one further mandatory input. Civil Code §5551 requires the board of an association of a condominium project, for buildings containing three or more attached multifamily dwelling units (§5551(l)), to have a licensed structural or civil engineer or architect conduct a visual inspection, at least once every nine years, of a random and statistically significant sample of the exterior elevated elements the association is responsible for maintaining: the load-bearing components and waterproofing systems of decks, balconies, stairways, walkways and their railings that have a walking surface more than six feet above ground level, are designed for human use, and are supported in whole or substantial part by wood or wood-based products. The inspector’s written report must be presented to the board and incorporated into the reserve study (§5551(f), §5550). Under §5551(i) the first inspection had to be completed by January 1, 2025, and subsequent inspections run every nine years in coordination with the reserve study inspection; for a building whose permit application was submitted on or after January 1, 2020, the inspection must occur no later than six years after the certificate of occupancy is issued (§5551(k)). A reserve study for a building covered by this rule must incorporate the elevated-element inspection report (§5551(f)); on our reading, one that does not is incomplete.

How a Reserve Study Is Actually Done

Who prepares it. The law says the board must have the study done (§5550(a)), but not who has to do it, and California does not license reserve study preparers. In practice the board hires an outside reserve study company, often found and coordinated by the management company, with the contract approved by the board. Two voluntary credentials are common: Reserve Specialist (RS), from the Community Associations Institute, and Professional Reserve Analyst (PRA), from the Association of Professional Reserve Analysts. Many preparers follow the Community Associations Institute’s national reserve study standards. Asking who prepared your study, and with what credential, is a fair question.

How it is done. A full study starts with a site visit: the preparer lists every component the association maintains, measures it, looks at its condition, and estimates how long it will last and what it will cost to replace. From that it works out how much the reserves should hold and builds a 30-year plan of what goes in and what comes out. In the years between full studies, the preparer usually updates the numbers, with or without another site visit. California requires the site inspection at least every three years and a review every year (§5550(a)).

Who checks it. No state agency reviews or approves reserve studies. The checks are the board’s own: it must review the study every year (§5550(a)) and adopt the funding plan at an open meeting (§5560(b)). After that, the check is you. You can ask for the full reserve study plan (§5300(b)(3)), and you can inspect the association’s records (§5200, §5205).

It is an estimate, and the law says so. A reserve study is a forecast, not a measurement, and two competent preparers can reach different numbers for the same building. The one-page disclosure form every owner receives has to say that its figures “are based on the best estimates of the preparer at that time” and “are subject to change,” and it has to state the interest rate and the inflation rate the preparer assumed (§5570(a)). Three things decide how far the numbers can move:

• What the building has. A simple building has a short list: the roof, exterior paint, the elevator, the garage gate, the paving. A building with a pool, a gym, a clubhouse, and shared heating and cooling has many more components, each with its own forecast, and more room for error. More components also usually mean a bigger reserve.
• Age and condition. A new building’s forecasts are based on typical lifespans. An older building’s depend on what the inspector can see, and hidden problems (inside walls, under roofs, in pipes) are the ones that break the plan.
• Prices. Every future cost in the study is today’s price raised by an assumed inflation rate. If construction and repair prices rise faster than assumed, every future cost in the study is too low, and the plan falls behind without anyone doing anything wrong.

That is why the law asks for a review every year and a site inspection every three: the forecast is only as good as its last update.

What Changes in 2032: AB 2050

Everything above describes the law as it stands today. Nobody knows what else the Legislature will change in the coming years, but one change is already on the books with a start date: the reserve funding rules of AB 2050, which take effect on January 1, 2032. AB 2050 (Chapter 796, Statutes of 2026), signed on September 29, 2026, repeals the current reserve-study section on January 1, 2032 and replaces it with a rewritten reserve-study section (§5550) and a new reserve-funding section (§5552). Three changes matter most for the reserve study.

• An annual update, not just a review. From 2032, the association must “review and update this study annually” and implement necessary adjustments “to the association’s funding of the reserve account” (§5550(a), 2032 version).
• A minimum contribution level. The study must state the minimum reserve contribution level that keeps the projected reserve balance from falling below zero over the following 30 years (§5550(b)(6), 2032 version), and the association must fund at least that level every year (§5552(a)).
• Consequences if the projection dips below zero. If the study projects the balance below zero at any time in the next 30 years, the association must transfer at least 15 percent of its gross annual budget to reserves each year until it no longer does (§5552(b)). The test is the projection in the reserve study, which from 2032 must be updated every year (§5550(a) and (b)(6), 2032 version). If the budget cannot carry the transfer, the first fix, on our reading, is the ordinary one: raise regular assessments, which the board can do by up to 20 percent a year without a vote (§5605(b)). Only if the association is still unable to fund the reserves through its budget does it have to levy a reserve funding special assessment: up to 5 percent of budgeted gross expenses without a vote, counting all special assessments that year together, more with a member vote, and no more than once every nine years (§5552(c) and (e)). The statute itself says only “unable”; the order is our reading. How this works in numbers is in California HOA Reserve Law AB 2050: What Changes in 2032.

The new floor is not “fully funded.” It is the level that keeps the balance above zero, which is usually lower than the 100 percent figure in the percent-funded ratio below. Worked examples and the timeline are in California HOA Reserve Law AB 2050: What Changes in 2032.

How Much Has to Go In Each Year?

Today there is no legal minimum. The law makes the board find out the number: the study must estimate the total yearly contribution needed to pay for every major component over its life (§5550(b)(4)) and set out a funding plan with a schedule of any assessment changes needed to reach it (§5550(b)(5), §5560(a)). The board must adopt that plan at an open meeting (§5560(b)), but the Act does not force the board to fund it in full. The board decides through the annual budget, and any increase to fund the plan follows the normal assessment rules, including the 20 percent limit without a vote (§5560(c), §5605). What the board must do is tell you: whether the reserves will be enough in each of the next 30 years, and what extra assessments would be needed if not (§5570).

From January 1, 2032, under the law already passed, there is a floor. The association must contribute at least the minimum level its study calculates, the amount that keeps the balance from dropping below zero over the next 30 years, and if the balance is projected to go below zero it must move at least 15 percent of its gross annual budget into reserves each year (§5552(a) and (b)). That is a floor, not a target. The usual professional yardstick is the percent-funded number below.

The Percent-Funded Number

Every reserve study produces a percent-funded ratio: the current reserve balance divided by the fully funded balance the study says the association should have by that point. A 100 percent figure means the fund is exactly where it should be on a straight-line basis toward future replacement obligations. A 40 percent figure means the fund has less than half of what it should have.

Industry benchmarks, while not binding law, are roughly:

Percent Funded	Interpretation	Practical Implication
70%+	Strong	Low likelihood of special assessments
30–70%	Fair	Moderate special-assessment risk; active management needed
Under 30%	Weak	High special-assessment risk; significant owner exposure

The number is not a verdict; a well-run association with a high funded percentage may still face unexpected repairs, and an underfunded one may catch up through disciplined assessment increases. But it is a useful starting point. For a prospective buyer, a low percent-funded ratio is a negotiating point and a signal to look harder at the reserve study itself.

These bands are a matter of professional judgment, not law, and so is the target. Reserve professionals use three funding goals: full funding, which aims at or near 100 percent; threshold funding, which keeps the balance above a level the board chooses; and baseline funding, which only keeps the balance from ever falling below zero. The board chooses the goal, and the same building can have very different contribution figures depending on which one it picks. The fully funded figure itself rests on the same estimates of cost and life. The law even sets the formula for the disclosure (today’s replacement cost, multiplied by the years the component has been in service, divided by its useful life), and then says that formula does not require the board to fund to it (§5570(b)(4)). The 2032 floor under AB 2050 is, in effect, baseline funding.

What You Receive Every Year About the Reserves

You do not have to ask for the reserve study to see where the reserves stand. Every year, 30 to 90 days before the end of the fiscal year, the association must send you the annual budget report, and the reserve part of it is the part worth reading (§5300(a)). The full report, and what else it has to contain, is covered in The Annual Budget Report: What Your HOA Has to Tell You About the Money. On reserves, these are the four items worth reading first (the checklist below lists all of them, including the funding mechanism, the calculation method, and any loans, §5300(b)(6) to (8)):

• The numbers, in bold type. For each major component, its replacement cost, remaining life, and useful life; the cash the reserves should hold at year end and the cash they actually hold; the percentage of one to the other, which is the percent-funded figure; and the shortfall per unit (§5300(b)(2), §5565).
• The plan. A summary of the funding plan the board adopted, with notice that you can have the full reserve study plan on request (§5300(b)(3)).
• What the board has decided to put off. Whether it has decided to defer or not do the repair or replacement of any component with 30 years or less of life left, and why (§5300(b)(4)).
• What is coming. Whether the board expects a special assessment for a major component or to build up reserves, and if so how much, from when, and for how long (§5300(b)(5)).

With the report comes a one-page form, the Assessment and Reserve Funding Disclosure Summary (§5570, §5300(e)). It answers the question that matters in one line: will the reserves be enough in each of the next 30 years, yes or no. If no, it has to say what additional assessments or contributions would be needed, and it shows the percent-funded figure now, and for each of the next five years both with and without the funding plan being followed. Thirty minutes with that form once a year prevents most reserve surprises.

What Underfunding Actually Means

An underfunded reserve does not mean the work will not get done. It means the money to do the work will be collected later rather than now. That later collection typically takes one of three forms, each of which is harder on owners than steady reserve contributions would have been:

A special assessment. A lump-sum charge when the repair is needed. Owners pay thousands of dollars on short notice. The political pressure on the board to defer the repair goes up, which often leads to deferred maintenance and worsening problems.

A steep regular-assessment increase. A sustained catch-up through higher monthly dues, usually 15 to 20 percent year over year until the fund recovers. Owners on fixed incomes feel this most.

A loan. The association borrows from a bank, secured by the right to collect assessments. Interest and fees are paid by owners through higher assessments for years.

Every one of these costs owners more in the end than disciplined reserve funding would have. The association that runs at 30 percent funded is not saving anyone money; it is deferring pain onto future owners and amplifying it in the process.

---

What Owners Can Do

Reserve funding is a board decision, made through the annual budget. From January 1, 2032, that decision must also meet the minimum reserve contribution level described above (§5552(a)). Owners do not control the budget directly, but they have meaningful levers.

Read the reserve study and the reserve funding disclosure summary every year (§5570). Not skim. Read. If you cannot find them, request them; the association is required to distribute the disclosure summary with every annual budget report (§5300(e)) and to provide the full reserve study plan to any member on request (§5300(b)(3)).

Start with question 3 on the disclosure summary. Question 3 of the Assessment and Reserve Funding Disclosure Summary asks whether, based on the most recent reserve study and other information available to the board, currently projected reserve account balances will be sufficient at the end of each year to meet the association’s obligation for repair and replacement of major components during the next 30 years (§5570(a)(3)). If the answer is “No,” question 4 must list the additional assessments or other contributions to reserves, not yet approved, that would be needed (§5570(a)(4)).

Attend the budget-adoption board meeting. Under the Open Meeting Act, members have a right to attend and to speak (§4925(a) and (b)). A few informed owners at the budget meeting shift the conversation.

Ask the question in writing. “The reserve study shows a 28 percent funded ratio. The funding plan calls for a 15 percent annual contribution increase for the next three years. Is the board implementing the plan?” A written question creates a written record.

Use IDR and ADR where appropriate. Systemic underfunding combined with reserve-transfer violations can be a breach of fiduciary duty. IDR is an optional first step. Before filing certain lawsuits in superior court (those seeking only declaratory, injunctive, or writ relief, or that relief together with damages within the small claims limits), §5930 requires the parties to have tried to submit the dispute to ADR; small claims actions are exempt, and so are assessment disputes (§5930(b), (c), and (d)). See our article on the dispute resolution ladder.

Before buying, read the reserve disclosures. A resale seller must give you the most recent annual budget report and the other financial disclosures the association distributed with it, including the reserve summary and the funding-plan summary (§4525(a)(3)). The full reserve study is not on that list; ask the seller to request it from the association, which must provide the full reserve plan to any member on request (§5300(b)(3)). The seller must also hand over a copy of the report from the most recent exterior elevated element inspection (§4525(a)(11), §5551), so a buyer in a condominium project should ask for that report by name and read it alongside the reserve study. A percent-funded figure below 30, combined with a large upcoming component, is a negotiating point worth thousands.

For Boards: The Discipline That Avoids the Crisis

Boards that hit reserve crises almost always got there through a combination of keeping assessments artificially low and deferring the hard conversation about catching up. The alternative is not glamorous, but it works.

Adopt the funding plan the study recommends, and follow it. If the study calls for a 12 percent increase, adopt 12 percent. Every year the board defers the increase, the gap compounds. A regular assessment increase above 20 percent still needs a member vote (§5605(b)). From January 1, 2032, the association must also fund at least the study’s minimum reserve contribution level every year (§5552(a)).

Commission the study from a qualified reserve analyst. A cheap or lay-produced study understates both costs and remaining useful lives. That makes the funded-percent number look better on paper and leaves the association exposed in reality.

Do not transfer from reserves except where the law allows (§5510(b), §5515). Give advance notice in the board meeting notice (§4920), then record a written finding in the minutes (§5515(c)). Restore the money within 12 months (§5515(d)). The board may temporarily delay restoration only after giving the same notice and making a documented finding that the delay is in the community’s best interests (§5515(d)), and must levy a special assessment if necessary to recover the funds (§5515(e)). A single improper transfer, once discovered, can become a fiduciary-duty problem for the directors who approved it.

Disclose honestly in the reserve funding disclosure summary (§5570). Understated projections create owner expectations that cannot be met. Overstated projections invite political backlash. Accuracy is the cheapest long-term strategy.

Key Takeaways

The reserve fund is the association’s savings account for major repairs. California law requires most associations to have a reserve study every three years and to review it annually, and requires specific disclosures in the annual budget report and the reserve funding disclosure summary (§5570). From January 1, 2032, AB 2050 also sets a minimum annual reserve contribution. The percent-funded figure is the single most useful number for predicting special-assessment risk over the coming five years.

Owners who read the disclosures catch problems early. Boards that adopt the funding plan prevent crises. Associations that run underfunded for years end up paying more, through special assessments or loans, than disciplined reserve funding would ever have cost. The math is unforgiving in both directions.
