Quick Answer
A COA is a condominium owners association: the nonprofit entity that runs a condominium community and is made up of the unit owners. In a condo you own your unit plus a share of the common elements (roofs, hallways, grounds), and the COA maintains those shared parts, insures them, and collects assessments to pay for them. A POA in real estate usually means "property owners association," a broad term for an association over a neighborhood or master-planned community, and it is not the same as a power of attorney.
HOA, COA and POA: How the Terms Compare
The three acronyms describe owner-run associations, and in practice the labels overlap. What actually matters is the legal structure of the community and what the recorded documents say, not the name on the door.
| Term | Stands for | Typical community | What owners own |
|---|---|---|---|
| HOA | Homeowners association | Single-family subdivision, townhomes or planned community | The lot and the home, with shared amenities held by the association |
| COA | Condominium owners association | Condominium building or condo community | The unit (as defined in the declaration) plus a shared interest in common elements |
| POA | Property owners association | Larger or master-planned community, lake or resort community, sometimes a master association over several smaller ones | Varies by community |
Some states or developers use "association" for everything, and a single community can have more than one layer, such as a master association over a neighborhood HOA and a condo COA. The recorded declaration tells you which one governs you. For the legal-structure differences in more depth, read HOA vs. Condo Association, Types of Community Associations, and our HOA vs. POA guide.
What "POA" can mean in a real estate search
In a listing or disclosure, POA most often means property owners association. Outside community associations, POA is also a common abbreviation for power of attorney, which is a legal document that lets someone act for another person. If you see it in a purchase contract, read the surrounding words to see which one is meant.
What a COA Controls
A condominium is created by recording a master deed or declaration (the name varies by state) that divides the property into individually owned units and jointly owned common elements. The COA exists to administer what that document and the bylaws assign to it.
Common elements
Common elements are the parts of the property that are not inside a unit. Typical examples are the roof, structure, lobbies, corridors, elevators, parking areas, grounds and amenities. Some condominiums also have limited common elements, such as a balcony or assigned parking space, that only certain units use but the association may still maintain. The declaration lists which is which, and it is the first document to read when a repair question comes up.
Governing documents
- Master deed or declaration: creates the condo, describes the units and common elements, and sets maintenance and use rules.
- Bylaws: cover how the association operates, including board elections, meetings and assessments.
- Rules and regulations: board-adopted day-to-day rules such as quiet hours, pet rules and moving procedures.
- Budget and financial statements: show how assessments are spent and saved.

Powers and duties
A COA board usually has authority to collect assessments, maintain and insure the common elements, hire vendors and managers, adopt and enforce rules, and keep records. Those powers come from the documents and state condominium law, and they come with duties to owners, including budgeting and recordkeeping. Boards that outsource the daily work to a manager still keep final responsibility. See Condo Association Management: A Guide for Boards.
Unit Owner vs. Homeowner Responsibilities
The biggest practical difference between a condo and a single-family home is shared ownership of the building. The Maryland Insurance Administration puts it this way: unlike a homeowner, "the owner of a condominium unit does not own the building in which their unit is located, nor the land on which the building sits." That is a Maryland regulator's description, and in practice the exact boundary between "your unit" and "the association's building" is drawn by your declaration.
| Item | Often the association | Often the unit owner |
|---|---|---|
| Roof and building structure | Yes, in most condos | No |
| Hallways, lobbies, elevators | Yes | No |
| Grounds and amenities | Yes | No |
| Interior finishes, fixtures and appliances | Depends on documents | Usually |
| Balcony or patio | Depends; often limited common element | Depends; often use and cleaning |
| Plumbing, wiring and HVAC serving one unit | Depends on where the line is drawn | Usually, inside the unit |
| Assessments | Sets and collects | Pays |
The right-hand column says "often" and "usually" on purpose. Documents differ, and a question like who pays for a leaking pipe inside a wall is answered by your declaration, not by a general rule. When in doubt, ask the board or manager for the maintenance chart, if the community has one.
Owner obligations
- Pay assessments on time.
- Follow the declaration, bylaws and rules.
- Maintain the interior and anything the documents assign to the owner.
- Get approval before alterations that affect common elements, such as flooring in some buildings or exterior changes.
- Carry the insurance the documents or your lender require.
Insurance: Master Policy vs. HO-6
Condo insurance is split between two policies. The following description comes from the Maryland Insurance Administration's consumer FAQ and is a general explanation, not a promise of what your policy covers:
- The master policy is held by the association. It generally covers property damage to common areas and the exterior and structure of the buildings, provides liability coverage for accidents in the common areas, and is paid for through assessments to unit owners. It has deductibles the association chooses.
- The unit owner's policy (HO-6) is bought by the owner. It covers the interior of the unit and any improvements, personal belongings, and liability for accidents inside the unit. Optional add-ons include loss of use and loss assessment coverage.
The same source notes that an HO-6 policy "may only cover the interior of the unit and its contents," and that owners should confer with the association and review the bylaws to confirm which elements the master policy covers and which they must insure themselves. It also says Maryland law does not require an HO-6, but a lender or the association's documents often do.
Deductibles and loss assessments
A common surprise is the master policy deductible. As an example, the Maryland Condominium Act (Real Property Article § 11-114) provides, per the regulator's summary, that if damage originates from a particular unit the owner of that unit is responsible for the master policy deductible up to $10,000, and that if it originates from the common elements the deductible is a common expense shared by all owners. Other states handle this differently. Loss assessment coverage on an HO-6 can pay an owner's share of an association assessment after a large loss, which is why many owners add it. For the association's side, see the HOA insurance guide.
COA Reserves and Structural Rules: A State Example
Some states put extra duties on condominium associations because of the shared building. Florida is one example. Its condominium statute (718.112(2)(g)) requires a residential condominium association to complete a structural integrity reserve study at least every 10 years for each building three habitable stories or higher, covering items such as the roof, structure, fireproofing, plumbing, electrical systems, waterproofing and windows. See operating funds vs. reserve funds for how reserves work generally. Other states have no comparable rule, so confirm what your state requires.
What Owners Should Do
- Read the declaration and bylaws before you buy, focusing on who maintains what and what rules limit rentals, pets and alterations.
- Ask for the budget, the latest financial statement and the reserve study.
- Get a copy of the master policy certificate and ask about its deductible, so you can size your HO-6 and any loss assessment coverage.
- Ask your insurance agent to compare your HO-6 coverage against the declaration's definition of your unit.
- Attend board meetings or read the minutes, especially when a large repair or special assessment is discussed. See condo special assessments.
- Report common-element problems to the board or manager in writing and keep copies.
Frequently Asked Questions
What is a COA in real estate?
A COA is a condominium owners association. It is the entity made up of unit owners that maintains and insures the common elements, adopts a budget, collects assessments and enforces the declaration and rules.
What is the difference between a COA and an HOA?
A COA governs a condominium, where owners hold a unit plus a share of common elements. An HOA usually governs a subdivision or planned community where owners hold their own lots and homes. The names are used loosely, so the recorded documents decide which structure applies.
What is a POA in real estate?
Most often it means property owners association, a broad term for an association that governs a neighborhood or larger planned development and its common areas. In a legal context POA can also mean power of attorney, which is unrelated.
What does a COA cover?
That depends on the declaration, but it generally maintains and insures the common elements and structure, and pays for shared services. Owners generally handle the interior of their unit and personal belongings. Check the maintenance responsibilities section of your documents.
Do I need my own insurance if the COA has a master policy?
Usually yes, because the master policy often does not cover your belongings, interior improvements or your personal liability. Lenders and association documents commonly require an HO-6 policy. Confirm with your association and insurance agent.
Can a COA charge special assessments?
Generally yes, when the budget and reserves do not cover a cost, though the approval process depends on your documents and state law. For example, California Civil Code § 5605 requires owner approval for special assessments over 5 percent of budgeted gross expenses in the aggregate in California associations. Other states differ.
