What Is a Condominium?
A condominium (commonly "condo") is a form of real property ownership in which the buyer holds fee simple title to an individually defined unit within a larger multi-unit building or complex, plus an undivided interest in the project's common elements—lobbies, hallways, elevators, recreational facilities, and structural components. The unit owner's title and their proportional share of common elements are conveyed together as a single indivisible ownership interest.
The condominium is not a building type; it is an ownership structure. Physically, a condominium complex may be a high-rise tower, a garden apartment community, a townhome-style attached development, or even a row of detached homes within a common-element regime. What makes a development a "condominium" is the legal framework of unit ownership plus common area shared interest, established by the recording of a condominium declaration, plat, and CC&Rs.
How Condominium Ownership Works
Unit Boundaries
The condominium declaration specifies exactly where each unit's boundaries are located—critical because it determines what the owner is responsible for maintaining and insuring. Common boundary definitions include:
- All-inclusive: Unit walls, floors, ceilings, fixtures, and finishes are part of the unit. The owner owns everything from paint surface to paint surface.
- Bare walls in: Unit ownership begins at the unfinished interior surface of boundary walls, floors, and ceilings. Drywall, flooring, and fixtures within the unit belong to the owner; the structural wall itself belongs to the common elements.
- Centerline: Ownership begins at the centerline of shared walls, floors, and ceilings.
The specific boundary definition determines the owner's insurance obligations (what the master policy covers vs. what the owner must insure individually) and maintenance responsibilities.
Common Elements
Common elements are the portions of the project shared among all unit owners: structural systems, roofs, parking areas, walkways, amenities, and land. Each unit owner holds an undivided percentage interest in the common elements, typically proportional to unit size or established in the declaration. This interest cannot be transferred separately from the unit; they are conveyed together.
Limited common elements are portions of the common elements reserved for the exclusive use of one or more—but not all—unit owners: assigned parking spaces, private balconies, or storage units. Limited common elements are not the unit owner's fee simple property, but the owner has exclusive use rights.
Homeowners Association
Every condominium project has an HOA that manages common elements, enforces CC&Rs, and assesses dues. The HOA is governed by its declaration (CC&Rs), bylaws, and elected board of directors. For condominium projects, the HOA's financial health is critically important: if the HOA is underfunded, deferred maintenance accumulates, which can impair unit values and the HOA's ability to maintain habitability standards.

Condominium Financing
Financing a condominium unit involves an additional layer of scrutiny not present in single-family home purchases: the lender evaluates not only the borrower's creditworthiness and the unit's value, but also the financial health and legal status of the entire condominium project.
Warrantable vs. Non-Warrantable
Fannie Mae and Freddie Mac publish condominium project eligibility guidelines that determine whether a loan on a condo unit can be sold to the secondary market. Projects that meet these guidelines are called "warrantable"—conventional financing at market rates is broadly available. Key warrantability criteria include:
- Owner-occupancy rate of at least 50% of units
- No single entity owning more than 10% of units (Fannie) or 20% of units (Freddie) for projects over 21 units
- No pending or active litigation affecting the project's structural integrity or HOA finances
- HOA budget reflects adequate funding with no delinquency rate above 15%
- Commercial space does not exceed 35–50% of the project's total floor area
Projects failing these criteria are non-warrantable, requiring portfolio lending at higher rates with larger down payments. Buyers should verify a project's warrantable status before assuming standard financing is available. Approval AI assists buyers in identifying condo project approval status and navigating the documentation requirements lenders impose for condo projects.
FHA Condo Approval
FHA loans require the condo project to be on HUD's approved condominium project list—a separate approval process from conventional warrantability. Not all projects that are conventionally warrantable are FHA-approved, and vice versa. HUD allows single-unit approval (spot approval) for certain projects not on the full approval list, subject to additional conditions.
Insurance in Condominium Ownership
The division of insurance responsibility between the HOA's master policy and individual unit owners varies by project type and declaration terms:
Master policy: Covers the building's structure, common elements, and typically the "bare walls" of each unit. May be written on an "all-inclusive" or "bare walls in" basis, which determines whether the owner's improvements within the unit are insured by the master policy or by the individual owner.
Unit owner's policy (HO-6): Covers the owner's personal property, improvements and betterments within the unit, and loss assessment coverage (which covers the owner's share of assessments imposed by the HOA for losses exceeding the master policy). Liability coverage is also included.
