Owning a condo works like this: you hold full title to your individual unit, and you share ownership of the building’s common areas with every other owner in the development. That dual arrangement is what shapes everything else about condo life. You pay monthly assessments to a homeowners association that maintains the shared property, you follow rules set out in recorded governing documents, you carry your own insurance policy to cover the inside of your unit, and you participate in a community run by an elected board of fellow owners.
What You Own and What You Share
Your deed covers a specific unit, usually defined as the interior airspace within the walls, floors, and ceilings. The finished surfaces inside — paint, flooring, wallboard, tiles — are yours. The structural components behind those surfaces, like studs, concrete, and load-bearing columns, belong to the community as common elements.
Along with the unit, you automatically receive an undivided ownership interest in those common elements. That includes the land beneath the building, the roof, exterior walls, lobbies, hallways, elevators, and shared amenities such as pools or fitness centers. Your percentage of ownership is usually based on the relative size or value of your unit compared to the entire development, and that same percentage determines your share of the community’s costs.
A third category sits between the two. Limited common elements are spaces reserved for one owner’s exclusive use — a private balcony, patio, storage locker, assigned parking space — but technically still part of the common elements. Plumbing lines or air-conditioning units that sit outside your unit boundaries but serve only your unit often fall into this category too. Whether you or the association pays to maintain and repair them depends on the declaration.
Your unit, with its share of the common elements, is a separate parcel of real estate. You can sell it, lease it, or mortgage it the way you would a single-family home, and it is taxed as its own parcel by the local assessor.
The Monthly Bill, and the Bill You Didn’t See Coming
Condo ownership requires regular financial contributions, usually monthly or quarterly, often called HOA dues or assessments. These payments fund the association’s operating budget: building insurance, trash removal, landscaping, common-area utilities, management fees, and routine maintenance of the shared property. The amount is tied to your ownership percentage or a formula set in the declaration.
A well-run association also directs a portion of each assessment into a reserve fund — a savings account earmarked for major future expenses like roof replacement, elevator overhaul, or repaving a parking garage. About 14 states require associations to conduct professional reserve studies, which evaluate the remaining lifespan and replacement cost of major building components. Where required, those studies are typically updated every three to five years.
When the reserve fund falls short of what a big repair actually costs, the board can levy a special assessment: a one-time charge divided among owners. Special assessments can run from a few hundred dollars for a modest project to tens of thousands of dollars for structural work or emergency repairs. Most governing documents require advance written notice, and larger assessments often require an owner vote before the board can impose them. Emergency repairs needed to protect health or safety may be an exception.
One financial detail that surprises new owners: monthly assessments are not tax-deductible. The IRS specifically excludes condominium association fees and common charges from the deductible expenses for a primary residence, and they do not count as real estate taxes because they are imposed by the association rather than a government.1IRS.gov. Publication 530 (2025), Tax Information for Homeowners Your property taxes, billed separately on your unit, are deductible under the same rules that apply to other homeowners, subject to the $10,000 SALT cap. If you rent the unit out, assessments may be deductible as a rental expense.
Who Fixes What
Maintenance splits along the physical boundaries of your unit. You handle everything “walls-in” — plumbing fixtures, electrical outlets, appliances, countertops, flooring, interior finishes. A leaky kitchen faucet or a broken dishwasher is yours. The association maintains the common elements: roof, exterior walls, foundation, elevators, shared mechanical systems, landscaping, and the infrastructure that serves the building as a whole.
Limited common elements are the gray zone. In many communities the owner handles routine upkeep of their balcony or assigned parking area while the association retains responsibility for structural repairs. Read the declaration before you assume anything, because the split varies from building to building.
Two Insurance Policies, Not One
Condo insurance works in two layers. The association carries a master policy that covers the building’s structure and common areas against hazards like fire and wind, plus liability for incidents in shared spaces. That policy does not protect what is inside your unit.
For the interior, you need your own policy, known as an HO-6. It covers your personal belongings, interior fixtures and improvements you have made, liability for accidents inside your unit, and additional living expenses if you are temporarily displaced. Most HO-6 policies also include a small amount of loss assessment coverage — often around $1,000 — which helps pay your share if damage to a common area exceeds the master policy’s limits. You can usually buy more loss assessment coverage through an endorsement. Both the association’s governing documents and your mortgage lender will typically require you to carry an HO-6.
The Rules You Agreed To
Every condo community is controlled by a set of legally binding documents recorded in the public land records. The declaration, sometimes called the master deed, is the foundational document. It legally creates the condominium, defines each unit’s boundaries, identifies common and limited common elements, and establishes the association. Because it is recorded like a deed, the declaration runs with the land and binds every future buyer.
Covenants, conditions, and restrictions (CC&Rs) set the rules on how you can use your property, covering things like exterior modifications, noise, pets, and parking. The bylaws govern how the association itself operates: board elections, meetings, voting rights, financial management. Violating the rules can bring fines, and persistent violations can result in a lien against your unit.
The Board and Your Vote
The association, usually organized as a nonprofit corporation, manages the property on behalf of all owners. A board of directors made up of fellow unit owners handles day-to-day decisions — hiring management companies, approving maintenance contracts, enforcing rules, managing finances. Boards are typically elected at an annual meeting.
Each unit usually carries one vote, though some associations weight votes by unit size or ownership percentage. Your vote matters for electing board members, approving changes to the governing documents, and weighing in on major financial decisions like large special assessments.
Renting Out Your Unit
Many associations restrict renting. Common rules include caps on the total percentage of units that can be rented at any time, minimum lease terms of six months or a year, and tenant application requirements. Some communities prohibit rentals entirely, or limit them to owners who have held the unit for a set period.
Short-term rentals through platforms like Airbnb are a frequent flashpoint. Associations can ban them through the CC&Rs or bylaws, and many have. Violations can bring fines and liens. If you are considering a condo partly as a rental, read the governing documents first, and remember that an association can amend its rental rules over time.
Pets and Assistance Animals
One boundary worth knowing: even when an association bans pets or restricts them by breed, size, or number, federal law requires an exception for assistance animals. Under the Fair Housing Act, it is illegal to refuse a reasonable accommodation that a person with a disability needs to have equal use and enjoyment of their home.2Office of the Law Revision Counsel. 42 U.S. Code 3604 – Discrimination in the Sale or Rental of Housing An assistance animal, whether a trained service dog or an emotional support animal, is not a pet under this law.
If the disability and the need for the animal are not obvious, the association can ask for reliable documentation from a healthcare professional. It cannot charge a pet deposit or pet fee for an assistance animal, require specific breeds or certifications, or deny the request unless the specific animal poses a direct threat or would cause significant property damage that no other accommodation could prevent.3HUD.gov. Assistance Animals Wrongful denials can be reported to the U.S. Department of Housing and Urban Development.
What Happens If You Fall Behind on Assessments
Unpaid assessments carry serious consequences. The association can charge late fees and interest on the overdue balance, and once the matter goes to an attorney, you become responsible for collection costs and legal fees too. In most states, the association can place a lien on your unit for the total owed — original assessments, accrued interest, fines, and attorney fees. That lien can be foreclosed much like a mortgage, meaning you could lose your home over unpaid dues.
In roughly 20 states, association liens carry what is known as “super-priority” status. For a limited portion of the debt, the association’s claim ranks higher than even the first mortgage, which means the association can sometimes foreclose ahead of the bank. The specifics — how many months of unpaid assessments qualify, redemption periods, judicial versus nonjudicial process — vary significantly by state. If you are falling behind, contact the board or management company early. Many associations will negotiate a payment plan before escalating.
Buying, Financing, and Selling a Condo
Getting a mortgage for a condo is not always as straightforward as for a single-family home. Lenders and the agencies that back mortgages — Fannie Mae, Freddie Mac, and the Federal Housing Administration — impose requirements on the condo project itself, not just on the borrower. A project that fails those standards may be ineligible for conventional or FHA-insured financing, which shrinks your buyer pool when you sell.
Project-level requirements typically include a minimum owner-occupancy rate, adequate reserve funding, limits on how many units a single entity can own, and financial health standards. Fannie Mae’s full review process, for example, requires that no more than 15 percent of unit owners be 60 or more days delinquent on their assessments.4Fannie Mae. Full Review Process High delinquency, thin insurance, heavy investor ownership, or pending litigation can disqualify a project, making it harder for buyers to secure favorable loan terms.
Some associations also hold a right of first refusal, giving the association or its members the option to match any outside offer before a sale goes through. When this right exists, the governing documents spell out the response window, commonly 30 to 90 days. It can slow a sale but rarely results in the association actually buying the unit.
Before you buy, you are entitled to a resale certificate or disclosure package from the seller. In many states the purchase contract is voidable until you receive it and have a short review period afterward. The package should include the declaration, bylaws, current rules, recent budget and financial statements, reserve information, and any pending lawsuits against the association. Pay particular attention to the reserve fund balance, delinquency rates, pending litigation, rental restrictions, and any special assessments that have been approved or are being discussed. A major project approved before closing typically becomes the buyer’s problem. Reviewing these documents carefully, ideally with a real estate attorney who handles condo transactions, is the best protection against unpleasant surprises after you move in.
