How to Read an HOA Reserve Study Without an Accountant

TL;DR: An HOA reserve study lists every major shared component (roof, pavement, siding), its expected life, and how much money should be set aside each year to replace it without a special assessment. Look at the "percent funded" number first — anything under 70% means the association is at real risk of a surprise bill. Most studies get updated every 3-5 years, and the difference between a "fully funded" plan and a "baseline" plan can mean thousands of dollars out of your pocket later.

Nobody hands you a decoder ring when the HOA board mails out a 40-page reserve study. You skim the cover, see a table full of numbers, and either trust it blindly or ignore it entirely. Neither is a good plan, because this one document tells you whether your dues are about to double.

What is an HOA reserve study, really?

A reserve study is an inventory of every component the association owns collectively — the roof over a condo building, the parking lot asphalt, the pool deck, the elevator, the siding — paired with two numbers: how many years each item has left, and how much it will cost to replace or repair when that day comes. A qualified reserve study provider, often a licensed engineer or reserve specialist, physically inspects the property and builds a 20 to 30-year funding schedule from that inventory.

The study exists because these big-ticket items don't fail gradually and evenly. A roof lasts 20-25 years, then needs full replacement in one lump sum. If the HOA hasn't been saving toward that cost the whole time, the board has two options: a special assessment or a loan, both of which land on your bill fast. This is the same logic that applies to single-family maintenance — the signs that your roof is aging faster than it should matter just as much at the HOA level, just multiplied across dozens of units.

How do you find the "percent funded" number and why does it matter?

The percent funded figure tells you how much money the association currently has in reserves compared to how much it should have based on the age and condition of its components — find it near the front of the report, usually in a summary table or executive summary page. A reserve at 100% funded means the HOA has exactly what the depreciation schedule says it should have on hand today. Most industry guidance treats 70% or higher as healthy, and anything below 30% as a warning sign that a special assessment is likely within a few years.

Community Associations Institute data has repeatedly shown that a majority of HOAs run underfunded, often sitting in the 40-60% range. That doesn't mean disaster is imminent, but it does mean you should ask the board directly: what's the plan to close the gap, and over what timeline? A board that dodges the question is more concerning than a board that shows you a 10-year catch-up plan with specific dues increases attached.

How do you check the component list for accuracy?

Compare the physical property to the study's component list line by line — this is where a lot of studies quietly go stale. If the report still lists a 2015 roof replacement that already happened, or doesn't mention a new deck that was added two years ago, the whole funding schedule is built on outdated assumptions. Reserve studies should be updated every 3-5 years with a full site visit, and a simpler "update without site visit" every year in between, per standard industry practice.

Pay close attention to the categories that fail early and expensively: siding, driveway and pavement heaving, gutters, and masonry. These are the components boards most often push down the priority list because nothing looks visibly broken yet, right up until water starts undermining a shared foundation and the fix costs far more than routine maintenance would have.

What's the difference between a full and baseline funding plan?

A full funding plan targets 100% reserves and keeps dues higher now to avoid future assessments, while a baseline plan only keeps reserves high enough to avoid the fund going negative, which usually means lower dues today but a higher chance of a special assessment down the road. Boards choose between these models based on owner tolerance for dues increases versus surprise bills, and the study itself should state which model it's using.

| Full Funding Plan | Baseline Funding Plan | |---|---| | Targets 100% funded | Targets fund never hits $0 | | Higher monthly dues now | Lower monthly dues now | | Special assessments rare | Special assessments more likely | | Predictable long-term costs | Costs shift unpredictably to owners |

If you're comparing two condo buildings before buying, ask each seller or board for the current percent funded and which model they use. A unit priced $10,000 cheaper next to a building running a baseline plan at 25% funded isn't actually cheaper once you account for the assessment risk.

Should you worry about a reserve study before buying into an HOA?

Yes — request the most recent reserve study and the last two years of board meeting minutes before closing, not after. The reserve study tells you the mechanical risk; the minutes tell you whether the board actually acts on it. A property with an aging electrical system, similar to homes still running on 100 amp service that can't handle modern loads, or a building with known chimney flashing leaks that never got fixed, will show up in both documents if you read them together.

Ask your real estate agent or attorney to flag any reserve study more than 3 years old, since that's past the standard update cycle and the numbers may no longer reflect real costs, especially after recent inflation in labor and materials.

FAQ

How often should an HOA get a reserve study done?

Most state statutes and industry standards call for a full study with a site visit every 3 to 5 years, with a simpler desktop update in the years between.

What percent funded is considered healthy for an HOA?

Above 70% is generally considered healthy, 30-70% is a caution zone, and below 30% signals a high risk of a special assessment within a few years.

Can I request a reserve study before buying a condo?

Yes, sellers and HOA boards are typically required to disclose the reserve study and recent financials during a resale disclosure package, so ask your agent to request it before you're under contract.

What happens if an HOA reserve fund runs out of money?

The board typically issues a special assessment billed to all owners, or takes out a loan that gets repaid through higher monthly dues, both of which can cost owners several thousand dollars with little notice.

Who actually prepares an HOA reserve study?

A licensed reserve specialist or engineer, often certified through organizations like the Community Associations Institute, inspects the property and builds the funding schedule based on component age and replacement costs.
