Condo capital improvements are large, value-adding projects to a building’s common elements — think roof replacements, elevator modernizations, or new mechanical systems — and they reach individual owners through reserve spending, special assessments, association loans, or some combination of the three. How the project is funded determines what you pay and when. How it’s classified determines your tax treatment. And the state of your association’s reserves determines whether a completed improvement helps your resale value or an unfunded one drags it down.
What Qualifies as a Capital Improvement
A capital improvement adds value to the property, adapts it for a new use, or meaningfully extends its useful life. Replacing an aging roof with a modern membrane system qualifies. So does installing a new elevator, upgrading electrical panels, or adding a lobby security system. The IRS draws the same line: improvements increase basis, repairs just maintain what’s already there.
Routine maintenance keeps the building running in its current condition. Repainting hallways, patching a few shingles, or servicing the existing HVAC all fall into that bucket, and associations expense those costs through the monthly operating budget. Capital improvements sit on the association’s balance sheet as assets and get funded differently.
The classification matters to you personally. A repair paid out of your regular dues has no effect on your unit’s tax basis. A capital improvement funded by a special assessment does. Associations sometimes blur the line on large projects that combine maintenance with upgrade components, so it’s worth reading the board’s project description carefully before you file.
How Projects Get Approved
Most capital projects start with a reserve study or engineering report flagging a component near the end of its useful life. The board reviews scope, cost, and urgency, then decides whether the project needs a vote of the full membership.
Whether owners vote depends on the declaration and bylaws. Many governing documents set a financial threshold: a project above a certain percentage of the annual budget triggers a membership vote, while smaller ones stay in the board’s hands. Votes that do go to owners commonly need a supermajority, often two-thirds of total ownership, rather than a simple majority. Before the vote, the association must send written notice detailing scope, estimated cost, and proposed funding. Notice periods and delivery rules vary by jurisdiction, but skipping steps or under-noticing owners can expose the assessment to legal challenge.
If you disagree with a project, the window to influence it is before the vote — attending meetings, requesting the reserve study, and reviewing the notice. Once a properly approved assessment is levied, your obligation to pay is legally binding.
How the Money Gets Raised
Reserve Funds
Reserves are the least disruptive source because the money was already collected through prior monthly assessments. A dedicated reserve account, funded to a target level set by a professional reserve study, pays for major repairs and replacements as building components wear out. The limitation is that reserves generally can only be spent on items identified in the study. An unexpected project outside the plan may not qualify even if the balance is healthy, and plenty of associations are underfunded to begin with.
Special Assessments
A special assessment is a one-time charge levied on every unit owner for a specific project. Your share is typically proportional to your ownership interest in the common elements, so a larger unit or higher percentage interest pays more. Many associations offer installment plans running from twelve months to several years, but the full amount is owed either way.
Nonpayment triggers the same collection process as delinquent dues: late fees, interest, and eventually a lien on your unit. In most states, an association’s lien for unpaid assessments takes priority over nearly all other claims except government tax liens and, typically, a first mortgage. A few states give the association a “super lien” that outranks a portion of the first mortgage balance. Unresolved debts can end in foreclosure. If you can’t pay, contact the board before the account goes delinquent; negotiating a plan is far easier than fighting a lien later.
Association Loans
When reserves fall short and a lump-sum assessment would create hardship, the association can borrow from a lender. The association is the borrower, and the loan is secured by future assessment income, not by individual units. You aren’t personally liable for the debt.
What you feel is the repayment. Principal and interest fold into the operating budget, so monthly assessments rise for the life of the loan, sometimes five to fifteen years. The total cost is higher than a one-time assessment because of interest, but the monthly hit is smaller and more predictable. Loan terms depend on the association’s financial health, collection history, and reserves.
Tax Treatment If You Live in the Unit
Your share of a capital improvement is not deductible in the year you pay it. It increases your unit’s adjusted cost basis, which the IRS uses to calculate profit when you sell.1Internal Revenue Service. Property (Basis, Sale of Home, etc.) 3 The IRS treats an improvement the same whether you paid a contractor inside your unit or paid a special assessment for common-element work: it adds value, extends useful life, or adapts the property to new uses, and the cost goes to basis.2Internal Revenue Service. Publication 523 – Selling Your Home
The federal rule requires expenditures properly chargeable to capital account to be reflected as basis adjustments.3Office of the Law Revision Counsel. 26 USC 1016 – Adjustments to Basis In practice, a $10,000 special assessment for a new roof on a unit you bought for $300,000 brings your adjusted basis to $310,000. At sale, you owe capital gains tax on $10,000 less in profit.
For most primary-residence sellers the larger shield is the Section 121 exclusion, which lets you exclude up to $250,000 in gain from the sale of your home, or $500,000 if married filing jointly, provided you’ve owned and lived in it for at least two of the five years before sale.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence The basis boost from capital improvements matters most when your gain exceeds those thresholds, which happens more often than expected in markets with long, steady price growth.
Tax Treatment If You Rent the Unit
Landlords get a more immediate benefit. You still can’t deduct a capital-improvement assessment in the year you pay it, but you can recover the cost through depreciation.5Internal Revenue Service. Publication 527 – Residential Rental Property Improvements to residential rental property, including your share of common-element upgrades, depreciate over 27.5 years on a straight-line basis.6Internal Revenue Service. Depreciation and Recapture 4 A $10,000 assessment yields roughly $364 per year in depreciation deductions against rental income.
Regular monthly assessments covering routine maintenance work differently. Because they maintain the property’s current operating condition rather than adding value, they’re fully deductible as operating expenses in the year paid.5Internal Revenue Service. Publication 527 – Residential Rental Property That’s why the association’s classification of a project matters: full deduction now, or spread across nearly three decades.
Keep every special-assessment receipt and every board resolution describing the project. You may need them years later to substantiate a basis adjustment or a depreciation claim.
What It Means When You Sell
A completed capital improvement generally supports resale value. Buyers expect a building with a new roof, modern elevators, and updated mechanical systems to hold value better than one with deferred maintenance. Trouble shows up during the project, when a large pending or recently levied assessment complicates a sale.
Buyers looking at a unit with an active assessment focus on how much remains unpaid and how long payments continue. A $30,000 assessment with two years of installments left is real money that buyers factor into their offer. Who owes the remaining balance after closing depends on how the assessment is structured and what the purchase contract says. In many associations, installments follow the unit — payments coming due after closing become the new owner’s problem unless the seller agrees otherwise. This is a common negotiation point and occasional source of litigation.
Sellers in most jurisdictions must disclose known special assessments through a seller disclosure statement, a resale certificate from the association, or both. Some states require disclosure only of assessments formally levied; others reach pending assessments or ones appearing in recent board minutes. If you’re buying, review several years of board meeting minutes and ask directly about planned major projects, because early-stage plans don’t always trigger disclosure.
Mortgage eligibility adds another layer. Fannie Mae and Freddie Mac set reserve funding minimums condo associations must meet for units to qualify for conventional financing. The minimum reserve threshold is rising from 10% to 15% of the annual budget, effective January 2027. Associations that maintain a current reserve study and fund at its highest recommended level may be exempt from the percentage rule. FHA has its own reserve requirements. An underfunded association that can’t meet these thresholds makes it harder for buyers to get conventional loans on units in the building, which suppresses demand and prices.
The Post-Surfside Shift Toward Reserve Studies and Inspections
The 2021 collapse of Champlain Towers South in Surfside, Florida, which killed 98 people, exposed the danger of deferred maintenance and underfunded reserves in aging condo buildings. Florida then required structural milestone inspections for condo buildings three stories or taller at 30 years of age, with follow-ups every 10 years.7International Code Council. How Building Codes Are Being Updated and Driving Development After the Surfside Condo Collapse Florida also now mandates structural integrity reserve studies covering roofs, load-bearing walls, plumbing, electrical systems, and other critical components, and owners can no longer vote to waive reserve funding for those items.
Other states and municipalities are watching Florida and considering similar rules. For owners, the practical effect is higher monthly assessments in buildings that were historically underfunded, along with better protection against catastrophic failure and the financial surprises of unfunded capital needs. If your association hasn’t run a reserve study recently, or your building is approaching a milestone age, expect inspections that may surface significant improvement needs. Buildings that get ahead of these requirements hold onto lending eligibility and resale values that buildings forced into emergency assessments lose.
