What Is an HOA Reserve Study, and Do We Need One?

TL;DR: A reserve study estimates when major components will fail and how much cash the HOA needs on hand — the single most important document for avoiding surprise special assessments.

If you're on an HOA board or living in one and wondering whether a reserve study is really necessary, the honest answer is: yes — a reserve study is the single most important document an HOA has for preventing surprise special assessments, and many states and lenders now require one.

Okoniq Property Hub keeps HOA governing documents — including the reserve study, the annual budget, and meeting minutes — in one place for residents and board members. Here's what a reserve study actually does.

What does a reserve study include?

A reserve study identifies every "major component" the HOA is responsible for maintaining — roofs, siding, asphalt, elevators, pools, boilers, mailboxes, fences, playground equipment, private streets — and for each one, it estimates:

• Remaining useful life (how many years until it needs replacement)
• Replacement cost in today's dollars
• Funding needed each year to be ready when the bill arrives

The output is a 20–30 year funding plan. If the community's reserve balance stays on track with the plan, big-ticket replacements happen without a special assessment. If reserves fall behind, a special assessment or emergency loan is coming — usually at the worst possible time.

Who prepares it?

A Reserve Specialist (RS) or Professional Reserve Analyst (PRA) designated by industry bodies like the Community Associations Institute (CAI) or the Association of Professional Reserve Analysts (APRA). They visit the property, inventory the components, gather cost data, and produce the report.

The trade group Foundation for Community Association Research publishes national statistics on reserve funding, and CAI has a reserve-study glossary and standards at caionline.org.

Is a reserve study legally required?

Depends on your state. As of 2026, many states either mandate reserve studies for condos and HOAs above a size threshold or strongly encourage them via disclosure requirements. Post-Champlain-Tower-South (2021), Florida overhauled its condo reserve laws for buildings 3+ stories. California, Virginia, Nevada, Washington, and several others also have varying rules.

Even where a study isn't legally required:

• Mortgage lenders increasingly require one before financing a unit in the community (especially Fannie Mae and Freddie Mac after 2022's condo project standard updates).
• Insurance underwriters may ask for it during renewal.
• Buyers ask for it during due diligence.

A community without a current study is quietly losing property values as buyers walk away.

How often should it be updated?

Best practice is:

• A full study every 3–5 years (on-site inspection, full recalculation)
• An update-with-site-visit in between years
• An annual budget review that reflects the study's funding recommendation

Skipping updates for a decade is how communities end up with dramatically underfunded reserves — see how to know if your HOA reserves are underfunded for the warning signs.

Keep HOA documents organized in one place

The reserve study is only useful if residents and board members can find it. Okoniq Property Hub stores HOA governing documents (bylaws, CC&Rs, reserve study, budget, meeting minutes) where owners can access them without having to email the property manager.

Frequently asked questions

What if our HOA has never done a reserve study?

You're not alone — a large share of HOAs still don't have one, particularly older or self-managed communities. The right move is to commission one now, before a major component fails. Starting late is much better than starting after a crisis.

How much does a reserve study cost?

For a typical 50–150-unit community, a full study runs roughly $3,000–$8,000; update studies are typically half of that. Larger communities pay more. Details in HOA reserve study cost 2026.

What is "percent funded"?

Percent funded compares your current reserve balance to what the reserve study says you should have at this point. Above 70% is generally considered strong; 30–70% is fair; below 30% is at high risk for a special assessment. It's the single most-cited number for reserve health.

FAQ

How long does it take to complete an HOA reserve study?

Most reserve specialists can complete a full study in 4–6 weeks from the initial site visit to final report delivery, though larger or more complex communities may take 8–10 weeks if access coordination or additional engineering input is needed.

Can an HOA board do a reserve study themselves instead of hiring a specialist?

Technically possible but not recommended — board-prepared studies lack the credibility lenders, insurers, and buyers expect, and boards typically underestimate replacement costs or miss components entirely, which defeats the purpose of having a study in the first place.

What happens if our reserve study shows we're severely underfunded?

The board has three options: raise monthly dues to catch up over several years, levy a one-time special assessment to close the gap immediately, or take out a loan — most choose a combination of modest dues increases plus a smaller special assessment to avoid sticker shock.

Does every component in the HOA get included in the reserve study?

Only components the HOA owns and maintains with a useful life longer than one year and a replacement cost typically above $1,000–$5,000 — so roofs and pools yes, but not landscaping contracts, monthly utilities, or general maintenance supplies.
