A condo building has no single owner. Each unit owner holds outright title to the interior of their own unit, and every owner together holds an undivided proportional share of everything else: the land, the structure, the roof, the hallways, the elevators, the pool. That is the short answer to who owns a condo building. A condominium association, made up of all the owners, manages the shared property on everyone’s behalf, but the association itself does not own it.
This split ownership is what defines a condominium and separates it from a co-op, where residents typically own shares in a corporation rather than real property.
What You Own Inside Your Unit
When you buy a condo, you receive a deed to a specific unit, the same way you would with any other piece of real estate. Your ownership runs from the finished interior surfaces inward. Paint, wallpaper, flooring, tile, interior partitions, and fixtures are yours. The structural framing, wiring, and plumbing behind those finished surfaces generally belong to the community as common elements, though pipes or ducts that serve only your unit are usually treated as limited common elements assigned to you.
Because you hold individual title, you can sell, refinance, or will the unit to someone without approval from other owners. You carry your own mortgage, pay your own property taxes, and handle the maintenance inside your walls.
What All Owners Own Together
Everything outside the unit boundaries belongs to all the owners collectively. The legal term is common elements, and each owner holds a proportionate undivided interest in them. “Undivided” means you don’t own a particular hallway tile or a specific corner of the parking lot. You own a percentage of all of it, and that percentage is set out in the condominium’s declaration.
Common elements generally include:
- Structural components: foundations, load-bearing walls, roofs, exterior walls, and the land the building sits on
- Building systems: elevators, central plumbing and electrical lines, HVAC equipment, and fire suppression
- Shared interior spaces: lobbies, hallways, stairwells, and mail rooms
- Amenities: pools, fitness centers, clubhouses, and landscaped grounds
Your ownership interest in these areas is permanently attached to your unit. You cannot sell it separately, and you cannot opt out of it. When the unit changes hands, the common element interest transfers automatically with the deed. The percentage typically reflects each unit’s relative size or value compared to the project as a whole, though the exact formula depends on the declaration.
That percentage is not just an abstraction. It drives your monthly assessment, in some communities your voting weight, and the share of sale proceeds you would receive if the condominium were ever terminated.
Limited Common Elements
Some parts of the property are collectively owned but reserved for the exclusive use of one unit or a small group of units. These limited common elements sit between private space and community property. A balcony attached to your unit, a basement storage locker, a reserved parking space, or an exterior patio typically fall into this category. You are the only one who can use them, but the community still owns them.
The distinction matters most when something breaks. Who pays to repair a balcony railing or resurface a reserved parking spot depends on how the governing documents allocate responsibility. Many declarations assign those costs to the owner who benefits from the limited common element. Others leave maintenance with the association. Reading your declaration before assuming either way is worth the time.
The Association’s Role: Manager, Not Owner
A condominium association is a legal entity, usually a nonprofit corporation, created when the condominium is established. Every unit owner is automatically a member. This is where new owners most often get the ownership picture wrong: the association does not own the common elements. The owners do. The association exists to manage those shared assets on the owners’ behalf.
A board of directors, elected from among the unit owners, runs the association. Board members owe a fiduciary duty to the association, which courts have interpreted as a responsibility similar to that of corporate directors. They are expected to act prudently, avoid conflicts of interest, and make decisions that serve the community’s long-term wellbeing rather than any individual owner’s preferences.
Assessments and the Power to Collect
The board prepares an annual budget covering landscaping, elevator maintenance, insurance premiums, management fees, and everything else needed to keep the shared property running. Each owner’s share of those costs is collected as a regular assessment, commonly called a monthly HOA fee. Fees range from a few hundred dollars in smaller communities to well over a thousand in high-rise buildings with extensive amenities, depending on what the building offers, how old it is, and how well-funded its reserves are.
If an owner stops paying, the consequences escalate quickly. Under the laws of most states, unpaid assessments automatically create a lien against the unit. That lien gives the association priority over many other creditors and, in most jurisdictions, the right to foreclose and force a sale of the unit to recover the debt. This can happen even if the owner is current on the mortgage.
When an expense arises that the regular budget and reserves cannot cover, the board can levy a special assessment, a one-time charge divided among all owners. Common triggers include storm damage, large insurance deductibles, unexpected structural repairs, and litigation costs. Special assessments can run from a few hundred dollars to tens of thousands per unit, and they are generally not optional. An owner who cannot pay faces the same lien and foreclosure consequences as someone who skips the monthly fees.
The Right to Enter Your Unit
Common element infrastructure, like water supply lines and structural columns, often runs through individual units. When something needs repair, the association generally has a legal right to enter your unit at reasonable times to access and maintain those components. Most governing documents spell out the notice requirements, and the right typically extends to emergencies where waiting is not practical, such as a burst pipe threatening neighboring units. Your unit is yours, but it sits inside a larger structure that belongs to everyone, and the law reflects that.
Where the Ownership Lines Are Written Down
Two recorded documents define the ownership structure of every condominium.
The Declaration
The declaration, sometimes called the master deed, is the document that legally creates the condominium. It is recorded in local land records and contains:
- A legal description of the entire property, including the land
- The precise boundaries of each unit
- Identification of all common elements and limited common elements
- The percentage of undivided interest in common elements allocated to each unit
- How common expenses are divided among owners
- Any use restrictions, such as limits on rentals, pets, or commercial activity
Declarations are difficult to amend, usually requiring a supermajority vote of owners, because they define the fundamental property rights of everyone in the building.
The Bylaws
Where the declaration creates the physical and ownership framework, the bylaws govern how the association operates day to day. They cover board election procedures, meeting schedules, quorum requirements, officer duties, and the process for adopting and enforcing rules. Think of the declaration as the constitution and the bylaws as the operating manual.
How Insurance Follows the Ownership Split
Because ownership is split, insurance is split too, and misunderstanding who covers what is one of the more expensive mistakes a condo owner can make.
The association carries a master insurance policy covering the building’s structure and common areas. For projects with conforming mortgages, the master policy must settle claims on a replacement cost basis and cover a broad range of perils including fire, windstorm, vandalism, and water damage.1Fannie Mae.

How far the master policy reaches into your unit depends on which type the association carries:
- Bare walls-in (studs-out): Covers the building’s structure, framing, and common areas. Everything inside your unit walls, including flooring, cabinets, fixtures, and appliances, is your responsibility.
- Single entity: Extends association coverage to include original unit fixtures and appliances as they were when first built, but excludes any upgrades or renovations you have made.
- All-in: Covers the structure, original unit components, and owner-made improvements.
Owners fill the gap with an HO-6 policy, the standard product for condo unit owners. It covers your personal property, interior damage not handled by the master policy, personal liability if someone is injured in your unit, and additional living expenses if your unit becomes uninhabitable. To the extent the master policy does not cover the interior of a unit or improvements to it, mortgage lenders require the borrower to carry an individual policy filling that gap.1Fannie Mae.

One add-on worth knowing about is loss assessment coverage. If the master policy is not enough to cover a major claim, or if the deductible is substantial, the board can pass the remaining cost to owners through a special assessment. Loss assessment coverage, an HO-6 rider, reimburses you for your share of that bill. Master policy deductibles on large buildings can run into six figures, so this relatively inexpensive rider matters.
When the Whole Building Can Be Sold
Ownership of a condo includes one more feature most owners never think about: under the right circumstances, the entire condominium can be dissolved and the property sold as a single parcel. In markets where land values have risen past the value of an aging building, it happens. A developer offers to buy the whole site, and if enough owners agree, the condominium ceases to exist.
The threshold for approval is high. Under the model Uniform Condominium Act adopted in various forms across many states, termination requires the agreement of owners holding at least 80 percent of the association’s voting power. Some states default to requiring 100 percent unless the declaration specifically authorizes a lower threshold, though the floor is typically 80 percent for projects with residential units. A declaration can always require more than the statutory minimum.
If a termination is approved and the property sold, proceeds are distributed to owners based on the appraised fair market value of each unit, its limited common elements, and its common element interest immediately before termination. Dissenting owners who voted against the sale still receive their share of proceeds, but they cannot block the transaction once the required supermajority is reached. Lienholders, including mortgage lenders, are paid from each owner’s share. During the period between the vote and the completed sale, owners generally keep the right to occupy their units and remain responsible for assessments.
For anyone buying into an older building on valuable land, the termination provisions in the declaration are worth reading closely. The difference between an 80 percent threshold and a unanimous requirement matters a great deal if a developer comes knocking.
