How to Read a Reserve Study

A reserve study is one of the most consequential documents in a condo resale package, and one of the most commonly misread. Most buyers glance at the percent-funded number, see something above 50%, and stop reading. The number alone tells you very little without understanding what went into it.

This article walks through the anatomy of a reserve study section by section, explains the key metrics, and describes what separates a credible study from one that should trigger follow-up questions.

What a Reserve Study Is — and Is Not

A reserve study is a long-range capital planning document, typically prepared by an engineer, reserve specialist, or both. It answers one practical question: does the association have enough money set aside to replace its major components as they wear out, without requiring an emergency assessment?

It is not a structural inspection. It does not evaluate whether components are safe today. It evaluates whether the association has a financially viable plan to replace them on the projected schedule. A building can have a perfectly adequate reserve fund and still have structural issues that the reserve study would not surface.

With that distinction in mind, here is what the document contains.

Section 1: The Component Inventory

The first substantive section of a reserve study is a list of every major component the study covers. For a mid-rise building this typically includes the roof, elevators, exterior painting, parking lot and driveway, pool and pool deck, HVAC systems for common areas, plumbing stacks in common areas, fire suppression systems, windows and exterior doors, and the building's waterproofing membrane.

What to check: Whether the list looks complete for the age and type of building. A 35-year-old building whose reserve study lists only six components is probably missing items. Compare the component list to the association's insurance schedule and to what you can observe physically. If the building has underground parking, a generator, a gym, or a significant lobby renovation, those should appear somewhere.

Section 2: Useful Life and Remaining Useful Life

For each component the study assigns two numbers: the total useful life (how many years the component is expected to last from installation) and the remaining useful life (how many years are left before it needs replacement or major renewal).

What to check: Whether the useful-life estimates are realistic. Roofs in hot, humid climates tend to fail earlier than manufacturer warranties suggest. Parking decks exposed to de-icing chemicals or salt air degrade faster than inland equivalents. Elevator systems in heavily used high-rises may need significant modernization well before their nominal life expires. A study prepared by an out-of-area firm using generic national tables may assign 30-year useful lives to components that local contractors would replace in 20. Optimistic life estimates push replacement cost into the future, which makes the percent-funded figure look better than the physical reality warrants.

Section 3: Replacement Cost Estimates

For each component, the study includes an estimated replacement cost in today's dollars, sometimes adjusted to a future-value figure using an assumed inflation rate.

What to check: When the cost estimates were last updated and whether they used local contractor pricing. A reserve study prepared in 2019 with costs that have not been revised for construction cost inflation — which ran at historically high rates through 2022 and 2023 — will systematically understate what it will actually cost to do the work. If the study is more than two or three years old and has no cost update, treat the replacement cost figures as optimistic floor estimates, not reliable projections.

Section 4: The Funding Plan

The funding plan is the study's recommended schedule of annual contributions to the reserve fund. It is the document's core output: given what components exist, when they will need replacement, and what replacement costs, how much should the association be collecting each year?

Funding plans come in two main varieties. A threshold-funded plan keeps the reserve balance above a minimum floor at all times — commonly expressed as "never fall below $X." A fully-funded plan attempts to keep reserves precisely in step with the cumulative depreciation of all components at all times.

What to check: Whether the operating budget's actual reserve contribution matches the funding plan's recommendation. This is the most common disconnect in association documents. The reserve study may recommend $180,000 per year; the budget may show $95,000. That gap has to close eventually — through higher dues, a special assessment, or both.

Section 5: Percent Funded

Percent funded is the ratio of what the association has actually saved (current reserve balance) to what an ideally funded plan would have saved at this point in the component life cycles. It is expressed as a percentage.

As a rough guide: above 70% is generally healthy; below 30% is a serious concern. The Florida SIRS framework references similar thresholds. These are guidelines, not hard legal standards — but they reflect decades of community association industry experience.

The limits of percent funded as a single number:

Percent funded is a snapshot. It tells you where the association stands today relative to an internally consistent model. It does not tell you whether the model itself is accurate. If useful-life estimates are stretched, if replacement costs are stale, or if significant components are missing from the inventory, the percent-funded figure will overstate true reserve adequacy.

Trend matters at least as much as the snapshot. An association at 40% funded that has been increasing its reserve contribution every year and has a credible multi-year catch-up plan is in a fundamentally different position than a 40%-funded association that has been flat for five years and still has a board that periodically votes to "defer" reserve contributions.

The Champlain Towers South association — whose collapse in Surfside, Florida in 2021 killed 98 people — was estimated to be approximately 6.9% funded. The association held roughly $706,000 in reserves against a projected capital need of approximately $10.3 million. The reserve shortfall did not cause the structural failure directly, but it foreclosed the practical possibility of addressing deferred maintenance at scale before the failure occurred.

What a Weak Reserve Study Looks Like

Not all reserve studies are created equal. Here are the characteristics that distinguish a credible study from one that should prompt additional scrutiny:

• Stale cost estimates. Replacement costs that have not been updated in three or more years, with no inflation adjustment.
• Optimistic useful-life assumptions. Remaining useful life estimates that seem long relative to the building's observable condition or the climate it operates in.
• Missing components. A component inventory that omits major systems visible in the building or in the insurance schedule.
• Funding plan disconnected from the budget. A recommended annual contribution that has no relationship to the number in the current operating budget.
• No site visit on record. A study prepared entirely from prior records without an engineer setting foot in the building.
• Single-year scope. A study that covers only what is needed for the next year's budget, without a 20- or 30-year projection.

The Fannie Mae Benchmark

Fannie Mae, which sets underwriting standards for a large share of conventional condo mortgages, uses a benchmark that at least 10% of the association's annual budget should be allocated to reserves. This is a minimum floor for loan eligibility, not an indication of strong funding. An association at 10% reserve contribution may still be severely underfunded relative to the actual replacement schedule — it just clears the threshold for Fannie Mae to purchase the loan.

If a reserve study shows the association needs 18% of budget to stay on track but the operating budget allocates 10%, the building will qualify for conventional financing while simultaneously falling behind on its capital plan.

Connecting the Reserve Study to Other Documents

The reserve study does not stand alone. Cross-referencing it against the financial statements and meeting minutes often reveals the clearest picture. Look for:

• The reserve fund balance in the financial statements vs. what the study's funding model predicts for this year.
• Any board discussion in the meeting minutes about deferring reserve contributions or borrowing from reserves to cover operating shortfalls.
• Any special assessments that were levied in the last two years — these sometimes signal that the reserve plan failed to anticipate a major expense.

This article explains how reserve study documents are structured and what the metrics inside them mean. It is not engineering or financial advice. If a reserve study reveals a significant funding shortfall or you cannot reconcile its numbers with the association's financial statements, an independent reserve specialist or a real estate attorney can help you assess the implications before closing.
