Reserve studies for 4–20 unit communities, explained

Most small HOA boards hear "reserve study" and picture something expensive and complicated — a thick binder from a consultant, a line item they can't afford, a process meant for 200-unit condo towers. So they skip it. They set dues based on what they've spent in recent years, keep a rough cushion in the bank, and hope nothing major breaks.

Then the roof reaches the end of its life. Or the shared fence fails. Or the asphalt on the parking area starts crumbling faster than expected. And the board faces a choice between a large special assessment or a dramatic dues increase, often at the worst possible time.

A reserve study doesn't prevent roofs from aging. It prevents the surprise.

What a reserve study actually is

At its core, a reserve study is 3 things rolled into one document:

An inventory. A list of the shared components your association is responsible for maintaining or replacing — roofs, siding, fencing, paving, drainage, landscaping infrastructure, and so on. Each item gets an estimated remaining useful life and an estimated replacement cost in today's dollars.

A funding analysis. A calculation of how much money your association should have in reserves right now, given the age and remaining life of your components, compared to how much you actually have.

A funding plan. A year-by-year schedule of how much to contribute to reserves so you can fund the expected replacements without large special assessments.

Some studies include a physical inspection by a reserve specialist. Others are "update" studies that rely on your own component data and adjust projections for inflation and interest. For a very small community, a straightforward update study — done by a specialist or done carefully in-house — is often more than adequate.

Why small communities need one

The most common objection is scale: "We're 6 units, we don't have a $50,000 roof problem."

But you do. You may have a smaller roof, but it will still need replacement on roughly the same timeline. And a $40,000 roof replacement divided by 6 units is a $6,700 special assessment — significant for any household. A $6,700 hit is easier to absorb if you've been collecting $40 per unit per month into reserves for 14 years. It's much harder if you've been contributing nothing.

The math works the same way at every scale. The difference is that small communities have less margin for error. There's no large reserve cushion to draw from, no ability to spread costs across dozens of units, and often no access to commercial credit on short notice.

Your state may also have disclosure requirements. Some states require sellers of HOA units to provide reserve study information to buyers. Boards that lack a study can face complications during resale, and owners who overpay for a unit they later discover is underfunded have grounds to feel misled.

Full study vs. annual update

There are 2 main types of reserve studies, and you don't need the most expensive one every year.

A full study with site inspection is done by a qualified reserve specialist who visits the property, inventories components, assesses conditions, and produces a detailed report. This is the most rigorous option and is appropriate when your community has never had a reserve study, when you've made significant changes to shared components, or when your existing study is more than 5–6 years old.

An update study (sometimes called a "no-site" update) takes an existing study and refreshes the financial projections — adjusting for inflation, updating the reserve fund balance, and revising contribution recommendations. An update can be done by a specialist or, in some cases, by a board member who maintains the component spreadsheet carefully. Annual updates keep your plan current without the cost of a full re-inspection every year.

A reasonable cadence for most small HOAs: commission a full study every 5 or so years, and update it annually in between.

Common shared components to inventory

If you're starting an inventory from scratch, these are the components most small HOAs are responsible for:

• Roofing (main building roof, covered parking canopies, carports)
• Exterior siding, stucco, or wood cladding — including paint cycles
• Windows and exterior doors in common areas
• Shared fencing (wood, metal, or masonry)
• Shared walkways, stairs, and railings
• Parking area paving — asphalt seal-coating and eventual resurfacing
• Drainage infrastructure (gutters, downspouts, area drains, dry wells)
• Common-area landscaping infrastructure — irrigation systems, retaining walls, major trees
• Exterior lighting fixtures
• Shared utility systems if applicable (water heaters, pumps, irrigation controllers)

Not every community has every item on this list, and some communities have items not on it. The goal is completeness — every component your association is obligated to repair or replace should be in the inventory with an estimated life and cost.

What "percent funded" means

Reserve studies typically express your reserve health as a percentage: how much money you actually have in reserves divided by how much you should theoretically have given the accumulated depreciation of your components.

A community that is 100% funded has exactly the amount it should, in theory, have accumulated. A community at 0% funded has no reserves at all. Most reserve specialists consider 70% or above a healthy position — you have enough buffer that normal timing fluctuations won't require special assessments.

Below 70%, you're in territory where unexpected acceleration of a major component could create real financial pressure. Below 30%, most specialists flag the community as significantly underfunded.

Don't treat the percent-funded figure as a grade. Treat it as a dashboard indicator. A number below 70% tells you the size of the gap you're filling; it doesn't tell you anything went wrong. Many communities inherit underfunding from previous owners or boards who kept dues artificially low.

How to read the funding recommendation without panicking

Reserve studies produce a year-by-year contribution schedule. Looking at year 1 can be jarring if you've been contributing much less than the recommendation suggests.

A few things to keep in mind when reading the numbers:

The recommended contribution is a target, not a legal requirement. You can choose to fund at a different level — just understand the tradeoff. Funding below the recommendation increases the probability and eventual size of a special assessment.

Studies often give you 2 or 3 funding scenarios: a "threshold" approach that keeps you above a minimum percent-funded floor, a "baseline" approach that tries to avoid deficits, and a "full funding" approach that targets 100%. For most small HOAs, the threshold or baseline approach is realistic starting point.

The recommendation is based on inflation and interest assumptions that may not match your real experience. Review the assumptions in the study — if they seem significantly off, ask the specialist about adjusting them.

How to phase contributions so dues don't spike

If your reserve study shows a significant funding gap, raising dues by the full amount in year 1 may be politically difficult or genuinely hardship-inducing for some owners. A phased approach works for most communities:

• In year 1, close 50% of the gap between your current contribution and the recommended amount.
• In year 2, close another 25%.
• By year 3, you're at or near the full recommended contribution.

This approach does mean your percent-funded improves more slowly and you may carry slightly higher special-assessment risk in the near term. But it's often the realistic path, especially if dues have been held flat for several years and owners need time to adjust their budgets.

When you communicate the increase to owners, be specific: share the current percent-funded figure, the component that drives the most exposure (typically the roof or paving), and the year it's expected to require significant investment. Owners who understand the math are more likely to support contribution increases than owners who receive a number with no context.

Turning a document into a practice

A reserve study is only valuable if you update it regularly and let it actually influence your dues decisions. The most common mistake small HOAs make is commissioning a study, filing it, and never looking at it again until the roof fails.

Set a calendar reminder to review your reserve fund balance and component inventory each year around budget time. If a component has deteriorated faster than expected — say, hail damage to roofing that shortens its useful life by 5 years — revise the estimate and adjust your contribution accordingly. That kind of ongoing attention costs almost nothing, and it's what separates boards that avoid surprises from boards that get blindsided.

A reserve study only works if the annual check-in actually happens. Keep your component list, your contribution schedule, and a recurring review date somewhere the whole board can see — a shared spreadsheet and a calendar reminder are enough to start. The tool matters less than the habit: a study that gets revisited every budget season is worth far more than a more detailed one that gets filed and forgotten.
