A reserve study is a professional engineering and financial report that inventories a building's major components, estimates when they will need replacement, and calculates how much the HOA should be saving each year to pay for those repairs without special assessments.
If you are buying a condo or townhome, the reserve study is one of the most important documents you can review. It tells you whether the building is saving enough money to handle future repairs or whether owners are likely to face unexpected bills.
Think of it as a financial physical for the building. It looks at everything that will eventually wear out and answers the question: is there enough money set aside to fix it when the time comes?
What a Reserve Study Includes
A reserve study has two parts: a physical analysis of building components and a financial analysis of the reserve fund.
The physical analysis is an inventory of all major components the HOA is responsible for maintaining. Roof, elevators, plumbing, HVAC systems, parking structures, pool, exterior paint, balconies, and more. For each component, the study estimates its current condition, remaining useful life, and replacement cost.
The financial analysis looks at the reserve fund itself. It reports the current reserve balance, calculates the percent funded ratio, recommends annual contribution amounts, and projects funding levels 20 to 30 years into the future.
Key metrics you will find in a reserve study include: percent funded, fully funded balance, recommended annual contribution, and a component list showing each item's remaining useful life and replacement cost. Most reserve studies project 20 to 30 years into the future.
Reserve Study Levels
There are three levels: Level I (full with site visit), Level II (update with site visit), and Level III (update without site visit).
Full Study
On-site inspection of all components. Full inventory. Most comprehensive. Required for the first study and every 3-5 years thereafter.
Update with Site Visit
Updates costs and conditions based on a new site inspection. No new inventory. Used between full studies to keep data current.
Update, No Site Visit
Desk review only. Updates financial projections using prior data. Least reliable. Cheapest option.
When buying, pay attention to which level was used for the most recent study. A Level III from five years ago is much less reliable than a recent Level I. If the HOA has only done Level III updates for several years, the component data may be significantly outdated.
Why It Matters When Buying a Condo
The reserve study tells you whether the building is financially prepared for future repairs or whether a special assessment is coming.
The reserve study reveals whether the HOA is saving enough. The percent funded ratio is the clearest indicator. 70% or higher is strong. Under 30% is a red flag.
It also shows which components are near the end of their useful life. If the roof has two years left and the elevator needs modernization within five years, those are major upcoming expenses. Low percent funded combined with aging components means special assessment risk is high.
Fannie Mae and Freddie Mac evaluate reserve adequacy as part of their condo project approval process. Starting January 2027, they will require HOAs to allocate at least 15% of their annual operating budget to reserves. Buildings that don't meet this threshold could lose conventional financing eligibility. Read more in our Fannie/Freddie condo rules guide.
Some states require reserve studies by law. Florida now mandates Structural Integrity Reserve Studies (SIRS) for certain buildings. Learn more in our Florida SIRS report guide.
How to Get and Read a Reserve Study
Request the reserve study during due diligence. Focus on percent funded, components at end of life, and the contribution trend.
You can request the reserve study from the seller, the HOA management company, or the HOA board directly. Don't wait for the 3-day HOA review period to start looking at documents. Ask early.
Key things to check:
- Percent funded: 70% or higher is strong. Under 30% is a red flag.
- Components at or past end of useful life: these represent deferred maintenance and potential near-term costs.
- Contribution trend: are annual contributions increasing to close the funding gap, or staying flat?
- Date and level of the study: a recent Level I is far more reliable than an old Level III.

Frequently Asked Questions
How often should an HOA update its reserve study?
Industry best practice is every 3 to 5 years for a full Level I study, with Level II or III updates in between. Some states mandate it. Florida requires Structural Integrity Reserve Studies (SIRS) by December 31, 2024 for buildings 3 or more stories and 25 or more years old.
What is a good percent funded in a reserve study?
70% or higher is considered strong. Under 30% is a red flag for special assessments. See our detailed breakdown at What Is Percent Funded?
Are reserve studies required by law?
It depends on the state. Florida requires SIRS for certain buildings. California requires reserve studies every 3 years. Other states have varying requirements. Even where not required, most well-managed HOAs commission them voluntarily.
Can I see the reserve study before buying?
Yes. You have the right to request it during due diligence. Ask the seller, listing agent, or HOA management company. If they refuse or delay, that itself is a red flag.
