Yes, when you buy a condo you do own part of the land, but not a specific piece of it. Your deed gives you two things bundled together: outright ownership of your individual unit and an undivided percentage interest in everything outside the units, including the ground beneath the building. That fractional interest is permanently attached to your unit and passes to the buyer when you sell.
The one exception is a leasehold condominium, where the association rents the land from a separate owner. In that arrangement, no unit owner holds any interest in the land at all.
What Your Deed Actually Conveys
Your unit is essentially the airspace within its boundary walls, as defined by the development’s declaration. Everything inside that boundary is yours to renovate, lease, or sell, subject to the community’s governing documents.
Outside the unit, you hold a percentage interest in the common elements. That interest is “undivided,” which means you share the entire property collectively with every other owner rather than owning a specific patch you could fence off. The declaration assigns each unit its own percentage, and those percentages must add up to 100%. Your percentage determines your share of association fees, your voting power, and your proportional stake in the land and shared property.
One rule catches new owners off guard: your common-element interest cannot be separated from your unit. You can’t sell the condo and keep your share of the pool, and you can’t transfer your land interest while retaining the unit. The two travel together as a single legal package.
The Land as a Common Element
The land is the most significant common element, but not the only one. Common elements also include the building’s foundation, roof, load-bearing walls, hallways, stairwells, elevators, and shared amenities such as pools and fitness rooms. All maintenance costs for these areas are funded through the fees every owner pays.
Between the fully shared and the fully private sits a middle category called limited common elements. These belong to the association but are reserved for one unit’s exclusive use. Balconies, patios, storage lockers, and assigned parking spaces are typical. You use your assigned balcony as if it were yours, but the association usually handles major structural repairs. The governing documents spell out who pays for what, and those rules vary from one community to the next.
When Nobody in the Building Owns the Land
Most condominium associations own the land in fee simple, and every unit owner gets a percentage of it. Not all do. In a ground-lease condominium, the association leases the ground from a separate landowner, and no unit owner holds any interest in the land itself. You own your airspace, and the association pays rent for the right to occupy the ground.
This changes the math in ways that matter. Ground leases typically include rent escalation clauses that raise the payment at set intervals, sometimes tied to the Consumer Price Index, sometimes to market reassessments. Those increases flow through to unit owners as higher monthly fees. When the lease expires, the land reverts to the landowner, and depending on the lease terms, the buildings and improvements may revert too. That would leave unit owners with nothing.
Financing a ground-lease condo is also harder. Many lenders won’t touch them if the remaining term is too short. FHA-insured loans require at least 55 years remaining on the lease, with an option for the lessee to extend to a total of 75 years from the date the mortgage is executed. Conventional lenders often impose similar minimums. If the remaining term falls below those thresholds, the buyer pool shrinks and resale values drop. Before buying any condo, confirm whether the development sits on owned or leased land. The declaration will tell you.
Where to Verify What You Own
A condominium doesn’t legally exist until its developer records a declaration with the county recorder’s office in every county where the property sits. The Uniform Common Interest Ownership Act, which forms the basis for condo law in most states, requires this declaration to be executed and recorded like a deed.
The declaration contains the legal description of the entire property, defines each unit’s boundaries, identifies what counts as a common element versus a limited common element, and assigns every unit its percentage interest. If you want to know exactly what land interest comes with a specific unit, or whether the association owns the ground at all, this is the document that answers it. Get a copy before you close.
A Note on Townhouses
Townhouses blur the line. In some developments, the owner holds title to both the structure and the land directly underneath it, much like a traditional house. In others, the townhouse is legally structured as a condominium, meaning the owner gets the interior space and a shared interest in the land. The only reliable way to tell is to check whether a recorded declaration exists for the development. If one does, you’re in a condominium regime regardless of what the marketing calls it.
What Shared Ownership of the Land Costs You
Owning a share of the land and common elements means sharing the cost of maintaining them. Your monthly assessment covers landscaping, hallway cleaning, elevator maintenance, insurance premiums for the master policy, and contributions to the reserve fund. Your share is proportional to the percentage interest assigned to your unit.
Reserve funds matter more than most buyers realize. Associations are supposed to save over time for major future repairs like roof replacement, elevator overhaul, or repaving. After the 2021 Surfside condominium collapse in Florida, several states tightened reserve requirements. Florida now mandates structural integrity reserve studies every ten years and requires associations to fully fund those reserves. New Jersey, Tennessee, and Maryland have enacted similar legislation with varying requirements. An underfunded reserve is a red flag anywhere. It means the next major repair could arrive as a special assessment.
Special assessments are one-time charges the board levies when regular fees and reserves can’t cover a necessary expense. A new roof on a large building can easily cost hundreds of thousands of dollars, and your share arrives as a bill that may be due in a lump sum or spread over installments. Reviewing the association’s most recent reserve study and financial statements before buying is the best way to gauge this risk.
If you fall behind on assessments, the association can place a lien on your unit. In many states, that lien carries limited priority over even a first mortgage for a defined period of unpaid assessments. The association can also restrict your access to shared amenities, sue for a money judgment, or in some cases foreclose on the lien entirely.
Property Taxes and the Land
Your property tax bill covers both your unit and your proportional share of the common elements, including the land. The local assessor treats each condo unit as a separate parcel of real property, not as a fraction of one large parcel. You receive your own tax bill, and your unit’s assessed value reflects both the interior space and your percentage interest in the shared property. Your tax bill already accounts for your ownership stake in the land, even though you can’t point to a specific piece of it on a map.
