Reserve Study for Condominiums: Requirements and What to

The Champlain Towers South collapse in Surfside, Florida killed 98 people in June 2021. NIST’s ongoing investigation points to long-deferred structural maintenance and a condo board that had repeatedly voted to waive reserve contributions as a root cause. That event changed the legal and regulatory landscape for condo reserve studies permanently—not just in Florida, but in how lenders across the country evaluate condo association financial health.

If you serve on a condo board, a reserve study is not optional paperwork. It is the foundational document of your fiduciary obligation to your homeowners.

How Condo Reserve Studies Differ from Single-Family HOA Studies

Single-family HOA reserve studies typically cover community-wide infrastructure: entrance monuments, perimeter fencing, parking lots, clubhouses, pools, and shared landscaping elements. The components are external and largely cosmetic or functional. When a parking lot fails, you resurface it. When a pool deck cracks, you repair it.

Condo associations own and are responsible for the building itself—or major portions of it. That means the reserve study must account for:

Structural and building envelope components: Roofing systems, exterior facades, waterproofing, windows and exterior doors, foundation elements, balconies and railings. These are expensive, complex, and in older buildings, potentially safety-critical.

Mechanical systems: Elevators are among the most expensive single components in a condo reserve study. A single elevator modernization can cost $150,000 to $300,000 or more. Buildings with multiple elevators, escalators, or freight lifts have substantially larger reserve obligations. HVAC systems serving common areas, boilers, cooling towers, and ventilation infrastructure also belong in the component list.

Parking structures: Underground or structured parking carries unique deterioration patterns—water infiltration, post-tension cable corrosion, concrete spalling—that standard reserve analysts without structural engineering expertise can miss. A specialist who has worked on parking structures specifically is worth seeking out.

Shared plumbing and electrical: Common-area and riser plumbing systems, electrical panels serving common areas, and life-safety systems (fire suppression, emergency lighting) all require reserve funding and specialized assessment.

The practical result: condo reserve studies are longer, more expensive, and require analysts with broader expertise than typical single-family HOA studies. Expect a full on-site study for a mid-sized condo to run $4,000–$8,000, with larger or older buildings pushing higher.

Florida’s Post-Surfside Requirements

Florida SB 154, enacted in 2022, created two new mandatory requirements for condo associations in buildings three stories or taller.

Milestone inspections require a structural inspection by a licensed engineer or architect at 25 years of age (30 years for buildings within three miles of the coastline), and every 10 years after that. Phase 1 is a visual inspection. If Phase 1 identifies concerns, a Phase 2 inspection requires destructive or intrusive testing to assess the extent of the problem. Results must be submitted to local building authorities.

Structural Integrity Reserve Studies (SIRS) require covered associations to commission a reserve study specifically addressing structural and safety components: roofing, load-bearing walls, floors, foundations, fireproofing, plumbing, electrical systems, windows, and waterproofing. The SIRS must be completed by December 31, 2024 for existing communities and every 10 years after.

Critically, SB 154 prohibited Florida condo associations from voting to waive or reduce reserves below the amounts required by the SIRS. This reversed decades of Florida practice where boards could vote annually to waive reserve contributions—a practice that Surfside revealed as catastrophically dangerous.

The NIST investigation into the Champlain Towers South collapse is ongoing as of this writing, but NIST’s findings on structural deterioration patterns from lack of maintenance have already informed how engineers approach condo reserve studies nationally.

What Lenders Check

When a unit in your building goes to market, the buyer’s lender evaluates the condo association’s financial health as part of the mortgage underwriting process. Fannie Mae’s selling guide governs most conventional mortgages.

For a condo project to be warrantable under Fannie Mae guidelines, it must maintain reserves of at least 10% of gross annual assessments. This is a floor, not a recommendation. Projects that fall below this threshold are classified as ineligible for conventional financing.

Beyond the 10% test, lenders also look for:

• Evidence of an adequate reserve study conducted by qualified professionals
• No significant deferred maintenance
• No pending litigation that could materially affect the association’s finances
• No single entity (investor or owner) controlling an excessive share of units

A condo association with a thorough, current reserve study is in a far stronger position during lender reviews than one presenting outdated estimates or no study at all. When units are difficult to finance, sale prices fall. Your reserve study is, indirectly, part of what maintains property values for all homeowners.

What Happens When a Condo Is Underfunded

Underfunded reserves in a condo are not just an accounting problem—they create a cascade of concrete consequences.

Special assessments. When a component fails and reserves are insufficient to cover it, the association must levy a special assessment. For a building-envelope repair or elevator replacement, that can mean $5,000 to $30,000 per unit with little notice. Homeowners on fixed incomes may be unable to pay. Some states restrict how quickly special assessments can be collected, creating a gap between the expense and the revenue.

Deferred maintenance. Boards with inadequate reserves defer maintenance because they lack the cash to address problems. Deferred maintenance accelerates deterioration—small water infiltration problems become structural damage, minor concrete spalling becomes a safety hazard. The Surfside collapse was, in part, the terminal result of decades of deferred maintenance that began with reserve underfunding.

Failed sales. When lenders discover reserve underfunding during mortgage underwriting, they decline the loan or offer non-warrantable terms. Buyers disappear or renegotiate prices downward. Owners who need to sell face a constrained market.

Board liability. Board members who knowingly approve inadequate reserve contributions may face personal liability claims from homeowners harmed by the resulting special assessments or deferred maintenance. The fiduciary duty that comes with board service is real and enforceable.

Running an Effective Condo Reserve Study Process

For most condo associations, the process looks like this:

1. Identify the right analyst. For buildings with elevators, parking structures, or buildings over three stories, prioritize analysts with engineering credentials (licensed PE) alongside reserve specialist credentials (RS or PRA). Structural complexity warrants structural expertise.

2. Prepare for the site visit. Gather your maintenance records, prior repair invoices, and any previous reserve studies. The analyst uses actual maintenance history to calibrate remaining life estimates. Missing records mean less accurate estimates.

3. Review the component inventory before signing off. Before the analyst finalizes the report, review the component list. If major systems are missing or useful-life estimates seem unusually optimistic, push back.

4. Use the funding schedule. The study’s recommended contribution schedule should feed directly into your annual budget process. A reserve study that recommends $200,000 per year in contributions but whose board budgets $120,000 is not protecting anyone.

5. Track reserve balance against the study. Your reserve fund balance, updated monthly, should be tracked against the study’s projected balance. If you fall behind—due to unexpected expenses or contribution shortfalls—you need to know immediately, not at the next three-year study.

BoardStack’s reserve tracking module is designed for exactly this workflow. Reserve and operating funds are separated at the database level—commingling is blocked, not just discouraged—and you can map your reserve study’s year-by-year contribution schedule directly into the platform to monitor adherence at every board meeting.

The 30-day free trial is available at $20/month for communities up to 50 homes, no credit card required. Start at /resources/guides/hoa-reserve-fund-compliance-guide/ if you need to understand the compliance framework first.
