01The 30-second summary
A reserve study is a financial planning document that identifies every major component the HOA is responsible for maintaining, estimates when each will need repair or replacement, estimates the cost, and calculates how much the association should be setting aside each year to pay for it.
Why do reserve studies exist?
Without a reserve study, HOAs fly blind on major expenses. A $200,000 roof replacement doesn't come with a warning — it comes with a special assessment that catches homeowners off guard. Reserve studies exist to spread those costs over time through regular monthly contributions, so the money is there when it's needed.
| Topic | What to know |
|---|---|
| What it covers | Major common-area components — roofs, paving, pools, elevators, paint, fencing, HVAC |
| Who does it | A qualified reserve study professional (some states require specific credentials) |
| How often | Most states require updates every 3–5 years; annual board review is standard |
| What it produces | A component inventory, condition assessment, funding plan, and percent-funded calculation |
| Who pays for it | The association — it’s an operating expense |
| Is it required | Yes in many states (CA, NV, UT, OR, WA); strongly recommended everywhere else |
| What “percent funded” means | How much of the ideal reserve balance the association actually has |
02Why should homeowners care?
You might never commission an HOA reserve study yourself — but there are specific moments when understanding your HOA reserve fund makes a real difference. Here are the most common:
- You're buying a home in an HOA and want to know if the reserves are healthy
- You received notice of a special assessment for a roof replacement
- Your monthly dues just increased and the board cited “reserve funding”
- You're wondering why your HOA has a large reserve balance but won't fix the parking lot
- You want to know if your HOA is saving enough for future repairs
- You're on a real estate listing and the HOA's “percent funded” number seems low
A well-funded reserve means fewer surprise assessments. An underfunded reserve means the money has to come from somewhere — and that somewhere is usually your wallet, all at once.
03Why should board members care?
If you're on an HOA board, the reserve study is your most important financial planning tool. It tells you what's coming, when it's coming, and how much you should be saving.
The most common situations where the reserve study drives board decisions:
- Deciding whether to raise assessments to fund reserves adequately
- Explaining to homeowners why dues are increasing
- Planning a major repair project and needing to know if reserves can cover it
- Responding to a buyer's agent who asks for the reserve study and percent-funded status
- Meeting state requirements for reserve study updates and disclosures
- Avoiding personal liability — underfunding reserves while knowing about deferred maintenance creates board exposure
Boards that maintain current reserve studies make better decisions, face fewer homeowner challenges on assessment increases, and avoid the crisis-mode special assessments that erode community trust.

04Common questions
The “percent funded” number in your HOA's reserve study doesn't mean what most people think. An HOA that's 70% funded doesn't have 70% of the money it will ever need — it has 70% of the money it should have right now based on how much its components have aged. An HOA at 30% funded isn't “almost broke” — it may have plenty of cash but be on a trajectory that leads to a shortfall when the next major expense hits.
Does my HOA need a reserve study?
In many states, yes — it's required by law. California requires a visual inspection every 3 years. Nevada requires reserve studies with NRED filing. Utah, Oregon, and Washington also have statutory requirements. Even in states without a mandate, reserve studies are considered a fiduciary best practice and are expected by lenders, buyers, and insurance companies.
Relevant law: CA: Civ. Code § 5550 · NV: NRS 116.31152 · UT: § 57-8a-211
What is percent funded and what's a good number?
Percent funded compares your actual reserve balance to your ideal reserve balance (the amount you should have based on how much your components have depreciated). The National Reserve Study Standards (NRSS) considers 70%+ to be “strong,” 30–70% as “fair,” and below 30% as “weak.” Most lenders and FHA certification require at least 10% of the budget going to reserves — but that doesn't guarantee adequate funding.
Relevant law: No universal statutory standard — industry benchmark from NRSS
Can the board skip the reserve study to save money?
In states with a statutory requirement, no. Even where it's not required by law, skipping the study doesn't save money — it just hides the problem. Deferred maintenance doesn't go away; it gets more expensive. Boards that skip reserve studies often end up levying larger special assessments later, which is more expensive for homeowners and creates more community conflict.
Relevant law: Varies — CA, NV, UT, OR, WA require studies
What's the difference between a full study and an update?
A full reserve study includes an on-site visual inspection of all major components plus a complete financial analysis. An update (sometimes called a “with-site-visit update” or “no-site-visit update”) refreshes the financial calculations based on current costs and the previous inspection data. Most states that require reserve studies mandate a full visual inspection every 3–5 years, with annual financial updates in between.
Relevant law: CA: Civ. Code § 5550 (3-year visual inspection minimum)
Who should do our reserve study?
A qualified reserve study professional. Many states don't require specific credentials, but the industry standard is a Reserve Specialist (RS) designation from the Community Associations Institute (CAI). Some states (like Nevada) require reserve study specialists to hold a state permit. Avoid using your general contractor or property manager — a qualified specialist provides independent, defensible numbers.
Relevant law: NV: requires RSS permit · Most states: no credential mandate but RS designation is industry standard
05Real-world scenarios
The special assessment surprise
A 100-unit community has been setting aside $15,000 per year for reserves — less than half of what the last reserve study recommended. When the roof needs replacement after 22 years, the cost is $380,000. The reserve account has $180,000. The board levies a $2,000 special assessment per unit to cover the gap. Homeowners who bought recently had no idea reserves were underfunded because they never asked for the reserve study during the purchase process.
What homeowners should have done: requested the reserve study and percent-funded status before buying.
What the board should have done: funded reserves at the recommended level from the beginning — the additional $15,000/year would have covered the shortfall over 13 years at ~$95/month per unit.
The well-planned replacement
A 60-unit community follows its reserve study recommendations and funds at 85% of the ideal balance. When the parking lot needs resurfacing at year 18 (cost: $120,000), the reserves have $102,000 allocated for that component. The board covers the remaining $18,000 from operating surplus and general reserves — no special assessment needed. Homeowners don't even notice because it was planned.
What the board did right: followed the reserve study funding plan consistently for 18 years.
What homeowners benefit from: predictable dues with no surprise assessments.
06What homeowners should remember
- Ask for the reserve study and percent-funded number before buying into an HOA
- A low percent-funded number means special assessments are more likely in your future
- Monthly dues going to reserves aren't wasted — they're preventing a larger bill later
- The reserve study should be available to all homeowners upon request
- If your HOA hasn't updated its reserve study in 5+ years, ask the board why
- Special assessments often result from years of underfunding reserves — not sudden emergencies
07What board members should remember
- Update the reserve study on the schedule required by your state (typically every 3–5 years)
- Fund reserves at the level recommended by the study — not at whatever feels comfortable
- Review the reserve study annually and adjust funding if costs have changed
- Disclose the reserve study and percent-funded status in annual reports as required
- Use a qualified reserve study professional — not your contractor or property manager
- Underfunding reserves while knowing about deferred maintenance creates personal liability exposure

FAQFrequently asked questions
What is a reserve study?+
A reserve study is a financial planning document for an HOA that identifies all major common-area components the association must maintain, estimates their remaining useful life and replacement cost, and calculates how much the association should save each year to pay for future repairs and replacements without special assessments.
How much does a reserve study cost?+
Typically $3,000–$8,000 for a full study with on-site inspection, depending on community size and complexity. Updates without a site visit are less expensive, usually $1,000–$3,000. The cost is an association operating expense paid from the general budget.
What is the difference between reserves and operating funds?+
Operating funds pay for day-to-day expenses: landscaping, insurance premiums, management fees, utilities. Reserve funds are set aside for major repairs and replacements that happen on longer cycles: roofs, paving, pools, elevators, exterior paint. Mixing the two is a common governance mistake that can mask underfunding.
Can homeowners see the reserve study?+
Yes, in virtually every state. Reserve studies are association records that members have the right to inspect. In California, the reserve summary must be included in the Annual Budget Report distributed to all members. If your HOA won’t share the reserve study, you likely have grounds to compel disclosure under your state’s records inspection law.
What happens if an HOA has no reserves?+
The association is entirely dependent on special assessments or loans to fund major repairs. When a $200,000 expense hits, every homeowner gets a bill — often thousands of dollars with little notice. Zero reserves also affect property values, make FHA/VA loan certification difficult, and increase the association’s insurance costs.
How often should a reserve study be updated?+
Most states that require reserve studies mandate a full visual inspection every 3–5 years, with annual financial reviews in between. Even in states without a requirement, updating every 3–5 years is industry best practice. Construction costs, component conditions, and interest rates change — an outdated study produces an inaccurate funding plan.
