Key takeaways
A component belongs in a reserve study when it passes a three-part test: the association is responsible for maintaining it, it has a limited and predictable useful life, and its repair or replacement cost is too large to absorb in the annual operating budget. Typical components include roofs, paving, painting, elevators, pool equipment, mechanical systems and building envelopes.
- The three-part test is common-area responsibility, a predictable useful life, and a cost too large for the operating budget.
- Industry standards also require a predictable remaining useful life; many studies include components with a remaining life under 30 years.
- Owner-maintained items, operating-budget items and components with no predictable end of life are typically excluded.
- Florida's Structural Integrity Reserve Study requires specific items, including roof, structure, fireproofing and fire protection, plumbing, electrical, waterproofing and exterior painting, and windows and exterior doors.

A reserve study is only as good as its component list. Leave something out and the plan underfunds it; put in the wrong things and the plan inflates dues. The good news is that the industry uses a consistent test to decide what belongs.
The three-part test
A component belongs in the reserve study when all three are true:
- Common-area responsibility. The association, not individual owners, is responsible for maintaining or replacing it. Check your declaration's maintenance responsibility chart; it often surprises boards.
- Predictable useful life. It wears out on a reasonably predictable schedule, so you can estimate when it will need work.
- Too costly for the operating budget. The repair or replacement is large enough that paying for it from a single year's operating budget would be disruptive.
CAI's National Reserve Study Standards frame the life test as both a limited useful life and a predictable remaining useful life. Many studies also set a horizon, typically components with a remaining life under 30 years, to match the funding plan.
Setting the cost threshold
There's no universal dollar threshold. A small community might reserve for anything over $1,000; a large high-rise might set its line at $10,000 or more. The test is relative: would this expense strain the operating budget? Some states set their own floor. Maryland, for example, applies its HOA reserve study rules to common-area components costing $10,000 or more.
What's typically included
| Property type | Common reserve components |
|---|---|
| All communities | Roofs, asphalt paving and seal coat, concrete flatwork, exterior painting, fencing, gates and access systems, signage, site lighting, irrigation controllers |
| Amenities | Pool and spa resurfacing, pumps and heaters, pool furniture, clubhouse interiors, fitness equipment, tennis and pickleball courts, playgrounds |
| Townhomes and condos | Siding, gutters and downspouts, decks and balconies, windows and exterior doors (where common), stairways, mailbox clusters |
| High-rises | Elevators, boilers and chillers, cooling towers, fire alarm and sprinkler systems, generators, domestic water pumps, roofing membranes, façade and sealant, parking garage structure and coatings, corridor finishes |
| Large-scale communities | Private roads, storm drainage and ponds, perimeter walls, entry monuments, golf and recreation facilities, landscape renovations |
What's typically excluded
- Owner-responsibility items, such as unit interiors or limited common elements the declaration assigns to owners
- Operating and maintenance expenses, such as landscaping contracts, routine repairs, janitorial service and small replacements
- Utility-owned infrastructure, such as lines and meters the utility maintains
- Components with no predictable end of life, such as building foundations under normal conditions
That last category is changing in some states. Florida's Structural Integrity Reserve Study requires condos and co-ops of three or more habitable stories to include the roof; structure, including load-bearing walls and primary structural members; fireproofing and fire protection systems; plumbing; electrical systems; waterproofing and exterior painting; windows and exterior doors; and any other item whose deferred maintenance or replacement cost exceeds the state reserve threshold ($25,675 in 2026). Structural items that older studies treated as "lifetime" now carry reserve obligations.
Common mistakes
- Missing components. A component left out gets funded from a special assessment when it fails.
- Lumping. "Building exterior" as one line hides very different lives for paint, sealant and siding.
- Using national costs. Replacement costs should reflect your market.
- Not updating after a project. A replaced roof still listed at its old age distorts the whole plan.
Keep the inventory current
Your component list changes every time you complete a project, add an amenity or learn something new about condition. In The Living Reserve Study®, components, costs and completed projects are updated as they change, so the funding plan always reflects what you actually own. See how it works.
