What is a condominium?
A condominium is individual ownership of a unit combined with shared ownership of the building's common elements through an association.
A condominium is individually owned housing within a building or community with shared common areas.
Where the word "Condominium" comes from
Condominium comes from the Latin com, together, and dominium, ownership, meaning shared ownership. The form lets individuals own a slice of a larger building while jointly owning its shared parts, and it became widespread in the United States in the 1960s.
Why Condominium matters
It makes apartment-style ownership possible by separating the unit from the common elements. The HOA manages the shared parts, spreading maintenance cost across all owners, which keeps large capital expenses like roofs and elevators affordable.
Common confusion about Condominium
A condo is owned, while a co-op is shares in a corporation that owns the building. Buyers sometimes confuse the two, but the legal structure, financing, and resale rules differ significantly, and co-op boards often have far more approval power over sales.
A real-world example of Condominium
You buy a condo: you own your apartment outright but share ownership of the roof, lobby, and gym with every other unit owner through the HOA. Your monthly dues fund that shared maintenance and the association's rules govern changes, so your control over the exterior is limited.
A worked example of Condominium
An owner wants to renovate their kitchen and replace the windows. The unit interior is theirs to change, but the windows are common elements controlled by the HOA, so the association must approve and often perform the work, with the cost shared among owners according to the governing documents. A plumbing leak behind a shared wall is similarly split, which is why the declaration's line between unit and common elements matters in every dispute.
How Condominium works in practice
Compare the condo fee and reserves against similar buildings, because a low fee can mask deferred maintenance that becomes a special assessment. Review the governing documents and any litigation the association faces. Lenders scrutinize HOA health, so a troubled condo can be harder to finance and resell than a well-run one, and a healthy reserve fund is worth paying for.
Questions about Condominium
What are condo fees?
Monthly dues that cover common-area upkeep and reserves.
Am I responsible for the roof?
No — the association maintains common elements like roofs.
Can the HOA tell me what to do inside?
Generally only where it affects common areas or the governing docs.
How is a condo different from a townhouse?
Townhouses are usually owned lot-and-structure; condos own only the unit volume.
