HOA Reserve Fund and Reserve Study Statistics (2026)

How big the community association sector is

According to the Foundation for Community Association Research's 2025 national and state statistical review (foundation.caionline.org), the United States had 373,000 community associations in 2025, holding 29.6 million housing units and 78.1 million residents, which is 35.2 percent of all U.S. housing. The Foundation says homeowners associations make up about 58 to 63 percent of that total, condominiums 35 to 40 percent, and cooperatives 2 to 4 percent. Those associations collected $124.2 billion in assessments, and one dollar in four, $31.1 billion, went to reserves.

What this means: Reserve funding is a $31 billion a year decision made by roughly 373,000 volunteer boards. Every one of those budgets rests on a judgment about the physical condition of roofs, paving, and mechanical systems that most board members never inspect themselves.

How many associations are underfunded: the "70 percent" number, traced

The most quoted statistic in this field is that "70 percent of HOAs are underfunded." We traced it. It comes from one firm, Association Reserves (reservestudy.com), and its own client data. According to Association Reserves' November 2025 underfunding analysis, 74 percent of associations were less than 70 percent funded across more than 100,000 reserve studies the firm prepared between 1986 and 2025. The firm states plainly that the dataset is its client portfolio, "rather than a national census." The share ranged from 61 to 73 percent for many years and reached 82 percent in the firm's most recent two-year study. Its April 2026 industry insights report gives the current split: 25.7 percent of clients are "strong" (70 percent funded or higher), 40.3 percent "fair" (30 to 70 percent), and 34 percent "weak" (0 to 30 percent).

What this means: The "70 percent" figure is real, but it is a vendor's client statistic, and the vendor is careful to say so. Cite it as "74 percent of Association Reserves' clients," not as a national census. The more useful lesson is in the update data: in Association Reserves' client data, associations that update every three years receive about half as many new special assessment recommendations as those that wait five. Current condition information is the cheapest form of reserve protection.

What the national standards define

According to the Community Associations Institute's Reserve Study Standards (caionline.org), first published in 1998 and updated in July 2023, a reserve study is "a budget planning tool" with two halves: a physical analysis (component inventory, condition assessment, life and valuation estimates) and a financial analysis (fund status and funding plan). The standards set four levels of service, from a Level I full study with an on-site inventory down to a Level IV preliminary study for a community not yet built, and three funding goals: baseline (cash never drops below zero, the riskiest), threshold, and full funding (at or near 100 percent). CAI's January 2024 resource compilation counted 12 states that require a reserve study or schedule and 12 that require reserve funding, as of October 2023.

What this means: The fully funded balance is a condition number dressed as a dollar figure. Effective age is set by what the inspector sees on site, so two identical roofs can carry different fully funded balances if one has been maintained and the other has not. The physical inspection is the input everything else is computed from.

State reserve study mandates, read from the statutes

We read each state's rule in the statute text on the legislature's own site. Florida is the strictest since Surfside: under Fla. Stat. 718.112(2)(g) (leg.state.fl.us), every residential condominium building three habitable stories or higher needs a structural integrity reserve study at least every 10 years. The study covers the roof, structure, fireproofing, plumbing, electrical, waterproofing and exterior painting, windows and exterior doors, and any other item over $25,000 that affects them. Owners can no longer waive those reserves for budgets adopted after December 31, 2024. Under Cal. Civ. Code 5550 (leginfo.legislature.ca.gov), California boards must have a visual inspection of accessible major components at least every three years. Nevada (NRS 116.31152, leg.state.nv.us), Virginia (Va. Code 55.1-1965, law.lis.virginia.gov), Maryland (Md. Real Property 11-109.4, mgaleg.maryland.gov), and Tennessee (Tenn. Code 66-27-403, via codes.findlaw.com) set five-year cycles. Utah (Utah Code 57-8a-211, le.utah.gov) requires an analysis every six years with an update every three. Washington (RCW 64.90.545, app.leg.wa.gov) and Oregon (ORS 94.595, oregon.public.law) require an annual update. Hawaii (HRS 514B-148, capitol.hawaii.gov) and Delaware (25 Del. C. 81-315, delcode.delaware.gov) attach funding floors. Colorado (C.R.S. 38-33.3-209.5, leg.colorado.gov) requires only a policy, and accepts an internally conducted study.

What this means: Every mandate in the table is, at its core, a mandated condition inspection on a clock: three years in California and Washington, five in Nevada, Virginia, Maryland, and Tennessee, ten in Florida. Florida goes furthest by pairing the reserve study with a separate engineer's milestone inspection and refusing to let owners vote the structural reserves away. Boards in the other 38 states are not off the hook; they simply have no statute setting the interval.

What lenders and FHA require

Lenders police reserves through the mortgage. According to the Fannie Mae Selling Guide, section B4-2.2-02 (fanniemae.com), a condo project passing Full Review must budget at least 10 percent of assessment income to replacement reserves, and a reserve study can substitute only if it is no more than three years old. According to Fannie Mae's Lender Letter LL-2026-03 of March 18, 2026, that minimum rises to 15 percent for loan applications dated on or after January 4, 2027, and from August 3, 2026 a lender relying on a reserve study may no longer accept a baseline funding plan. According to Freddie Mac's Single-Family Seller/Servicer Guide, section 5701.5 (freddiemac.com), at least 10 percent of an established project's budget must fund replacement reserves, and no more than 15 percent of units may be 60 or more days delinquent. According to HUD Handbook 4000.1 (hud.gov), FHA condo approval requires a reserve account funded with at least 10 percent of 12 months of unit assessments unless a reserve study no more than 36 months old, with a site visit, justifies less.

What this means: Association Reserves' own data says adequate funding runs 15 to 45 percent of budget, so the new 15 percent lender floor is still the bottom of the healthy range, not the middle. The tighter rule is the one on studies: from August 2026 a study only helps a condo qualify if the board is actually funding its highest recommendation, which means the inspection findings in that study flow straight into every unit's mortgage eligibility.

Florida's milestone inspections, by the numbers

Florida publishes statewide data on what its mandated structural inspections find. According to the Florida Office of Program Policy Analysis and Government Accountability's July 2026 report on milestone inspection reporting data (oppaga.fl.gov), building officials reported 8,736 completed phase one inspections and 1,575 phase two inspections for 2024 and 2025. Officials granted 1,587 deadline extensions (94 percent in coastal jurisdictions) and logged 903 permit applications for repairs valued from under $1,000 to $30 million. Inspections found 30 buildings unsafe or uninhabitable in 2024 and 24 in 2025, and most were not vacated. According to the Florida Department of Business and Professional Regulation's condominium inspections page (myfloridalicense.com), associations that existed on or before July 1, 2022 had to complete their SIRS by December 31, 2025 and report it to the Division within 45 days.

What this means: Building officials completed roughly one phase two inspection for every five and a half phase one inspections, and phase two is where a visual look becomes destructive testing and a repair permit. That ratio, and the $30 million top end on repairs, is what an unfunded reserve looks like when a licensed engineer finally writes it down. OPPAGA also notes the data is incomplete. Only 277 of 389 local enforcement jurisdictions reported 2024 data and 250 reported 2025 data, so these counts are floors, not totals.

What a reserve study costs

According to Association Reserves' FAQ page (reservestudy.com), the average cost of one of its professional reserve studies over the last 10 years was 0.84 percent of the association's annual budget, "slightly less than 1%," with price driven by level of service, property complexity, size, location, season, and turnaround. Vendor cost guides put dollar ranges on that. According to PropFusion's 2026 reserve study cost guide (propfusion.com), a full study runs $1,500 to $3,500 for a small HOA under 50 units, $2,000 to $7,000 for a typical 50 to 150 unit association, $5,000 to $10,000 for a large or complex community, and $7,000 to $15,000 or more for a high-rise or a Florida SIRS. These are one software vendor's published ranges, not a survey.

What this means: Against a $31 billion national reserve contribution, a study priced under 1 percent of budget is the cheapest line in the plan. Washington's statute exempts associations only when the study would exceed 10 percent of budget, more than ten times the typical price.

Component useful lives used in reserve planning

Reserve studies run on useful life estimates. A widely referenced public table is Fannie Mae's Form 4099.F estimated useful life tables for multifamily property (fanniemae.com), issued in August 2019 for physical condition assessments. It gives a 3-tab asphalt shingle roof 20 years, an EPDM or TPO built-up roof 20 years, and slate, clay, or concrete tile 40 years. Asphalt pavement gets 25 years with a 5-year seal coat cycle, and concrete pavement 50 years. Elevator machinery gets 30 years, but cabs and controllers 15. A pool plaster liner gets 8 years and a pool deck 15. Exterior painting gets 5 to 10 years, and vinyl or aluminum windows 30 years. Fannie Mae notes the values are standardized averages that do not replace the assessor's judgment about effective age and remaining life on a specific property.

What this means: Useful life is the denominator in every fully funded balance, so a roof carried at 20 years that is failing at 14 misstates the reserve by nearly a third. Effective age comes from what the inspector sees, which is why CAI's standards require the on-site condition assessment and why several states cap how long a study can go without one.

Claims we could not verify

Three widely repeated claims did not survive a trip to the primary source.

"70 percent of HOAs are underfunded," stated as a national fact. The number traces to an Association Reserves article that no longer resolves on the firm's site (it returned a 404 when we fetched it on September 5, 2026). The firm's current statement is 74 percent of its own clients across 1986 to 2025, and it says in the same article that the dataset "should be understood as findings from our reserve-study portfolio rather than a national census." No government or academic body publishes a national percent funded figure. Cite the 74 percent with its source and its caveat.

How often associations levy special assessments. We found no primary source that counts what share of U.S. associations levy a special assessment in a given year. The Foundation for Community Association Research defines special assessments only qualitatively as "one-time charges imposed when reserves or insurance are insufficient." Association Reserves publishes the relationship between percent funded and special assessment frequency among its clients, but as a chart without a national rate. Any page giving you a national percentage is estimating.

"FHA requires condo reserves of 20 percent." Several lender blogs say this. The current HUD Handbook 4000.1, revised August 13, 2025, says 10 percent of the aggregate of 12 months of unit assessments, with a reserve study exception. We could not find the 20 percent figure in any HUD document we fetched.
