HOA Reserve Study Guide: What It Is, Why It Matters, and What Boards Must Do

An underfunded reserve is how a well-run HOA becomes a crisis. One major repair — a roof, a pool resurfacing, a parking structure — and suddenly the board faces a choice between a painful special assessment and deferred maintenance that makes the problem worse. A reserve study is the tool that prevents that scenario. Most boards have one. Far fewer boards actually use it.

Here's what a reserve study actually is, what it tells you, and how to document reserve decisions properly in your board minutes.

What a Reserve Study Is

A reserve study is a financial analysis prepared by a professional reserve analyst or engineer that:

1. Inventories all of the association's major common area components (roof, pavement, pool equipment, elevators, fencing, lighting, etc.)
2. Estimates the remaining useful life and replacement cost of each component
3. Calculates how much the association should be saving each year to fund future replacements without resorting to special assessments
4. Assesses the current reserve fund balance against what it should be ("percent funded")

Think of it as a long-range maintenance budget. It tells you: over the next 30 years, these are the major expenses coming — and here's how to save for them systematically.

Who's Required to Have One

Requirements vary by state:

• California: Civil Code §5550 requires HOAs with 150+ units to conduct a reserve study at least every three years, with an annual review and update. Associations with fewer units are encouraged but not mandated.
• Florida: Florida Statutes §718.112 (condos) and §720.303 (HOAs) both require reserve accounts for specific components and mandate that reserve funding be included in the annual budget.
• Washington: RCW 64.38.070 requires HOA boards to adopt a reserve account and funding plan.
• Nevada: NRS Chapter 116 requires a reserve study and mandates funding at a specified level.
• Other states: Many have no statutory requirement, but best practice standards (and most mortgage lenders) expect adequate reserve funding.

Even where not legally required, most lenders and Fannie Mae/Freddie Mac guidelines require evidence of adequate reserves for buyers to obtain financing in your community. A poorly funded reserve can make units harder to sell.

Understanding Percent Funded

"Percent funded" is the most important number in the reserve study. It measures how much money you have in reserves compared to how much you should have, given the age and condition of your components.

• 100% funded: Ideal. You have exactly what you should at this point in the components' lifecycle.
• 70-100% funded: Strong. Some minor catch-up may be needed.
• 30-70% funded: Marginal. Higher risk of future special assessments.
• Below 30% funded: Critical. Special assessments or significant assessment increases are likely without corrective action.

The Community Associations Institute (CAI) recommends maintaining reserves above 70% funded. Many associations hover in the 30-50% range — not a crisis, but a reason to take funding seriously.

The Three Funding Plans

A reserve study typically presents multiple funding options:

Threshold Funding

Fund reserves just enough to avoid the reserve balance dropping to zero at any point. This is the minimum viable approach and carries the most risk — it leaves little margin for unexpected costs or component failures ahead of schedule.

Percent Funded Plan

Target a specific percent funded level (often 70-100%) and set annual contributions accordingly. More stable and less likely to require special assessments.

Full Funding Plan

Target 100% funded at all times. The safest approach, but requires the highest annual contributions. Appropriate for older communities with aging components.

The board must choose a funding plan and adopt it in the annual budget. This is a formal board decision that should be reflected in meeting minutes.

What to Document in Board Minutes

Reserve study and reserve fund decisions are high-stakes enough to require thorough documentation. Here's what your minutes should capture:

Annual Budget Adoption

When you adopt the annual budget, the reserve contribution rate should be explicitly documented:

Motion: T. Williams moved to adopt the fiscal year 2027 operating budget of $284,000 including a reserve contribution of $48,000 ($400 per unit), representing 85% of the reserve analyst's recommended funding level. Seconded by P. Chen. Discussion: The board reviewed the current percent funded (62%) and confirmed the contribution rate is consistent with the threshold funding plan adopted in 2024. Vote: 4-1. Budget adopted.

Reserve Study Updates

When the board reviews or commissions a reserve study:

The board reviewed the 2026 Reserve Study Update prepared by Pacific Reserve Analysts. Key findings: current percent funded is 58%, up from 51% in 2025. Recommended annual contribution is $52,000. The board discussed the gap between current contributions ($48,000) and recommended level. Motion: P. Williams moved to increase reserve contributions to $52,000 effective with the 2027 budget. Vote: 5-0. Motion carried.

Waiving or Reducing Reserve Contributions

Some governing documents allow the board (or owners) to waive reserve funding. If this happens, it must be thoroughly documented — including the reason and the vote. Underfunding reserves without documentation exposes board members to personal liability for breach of fiduciary duty.

Unplanned Reserve Expenditures

When the board spends reserve funds outside the planned schedule (emergency repairs, component failure ahead of projected useful life), document:

• What component failed and why
• The cost and which contractor was selected
• That the expenditure was from reserves rather than operating funds
• Whether a reserve study update is needed to reflect the revised component lifespan

Common Reserve Fund Mistakes

Treating reserves as a savings account to borrow from

Reserve funds are restricted. In most states and by most governing documents, they can only be used for the specific purposes they were collected for — major component repairs and replacements. Using reserves to cover operating deficits or unrelated expenses is a fiduciary violation.

Approving budgets without reviewing the reserve study

The reserve study should inform every annual budget. A board that adopts a budget without considering the reserve analyst's recommended funding level is making a decision without the relevant information — which is both bad governance and a breach of the duty of care.

Not updating after major expenditures

If you replace a roof five years ahead of schedule, the reserve study's projections are now wrong. The study needs to be updated to reflect the new component lifespan and revised funding requirements.

Letting percent funded erode without addressing it

Reserve funding is like compound interest in reverse — delay addressing a funding gap and it gets harder to close without dramatic assessment increases or special assessments. Address gaps incrementally before they become crises.

How MinuteSmith Helps

Reserve study discussions often get detailed — percent funded calculations, funding plan comparisons, long-term projections. The board secretary needs to capture the decisions accurately while the financial discussion is happening.

MinuteSmith records the full meeting and generates structured draft minutes that capture reserve fund motions, vote counts, and the key context behind each decision. Financial decisions are documented with the precision they require — without the secretary having to choose between listening and writing.
