Understanding Coverage B: Definition and Scope
In the world of property insurance, specifically within the Homeowners Policy (HO) forms, Coverage B is designed to protect structures on the residence premises that are separated from the main dwelling. To qualify for Coverage B, a structure must be separated from the primary dwelling by a clear space. This includes structures connected to the dwelling by only a fence, utility line, or similar connection.
For the Property & Casualty exam, it is vital to distinguish between what belongs under Coverage A (Dwelling) and what falls under Coverage B. If a garage is physically attached to the house, it is Coverage A. If that same garage is twenty feet away in the backyard, it is Coverage B. For more foundational information on policy structures, see our complete Homeowners exam guide.
Common examples of "Other Structures" include:
- Detached garages and carports.
- Storage sheds and greenhouses.
- Fences and gates.
- Swimming pools (depending on the carrier, though usually Coverage B if detached).
- Guest houses or "granny flats" (provided they are not used for business).
- Retaining walls that are not part of the dwelling.
Coverage A vs. Coverage B: Key Differences
| Feature | Coverage A (Dwelling) | Coverage B (Other Structures) |
|---|---|---|
| Primary Focus | Main residence and attached structures | Detached structures separated by clear space |
| Standard Limit | The Primary Limit (100%) | Automatically 10% of Coverage A |
| Connection Type | Physically joined or connected by breezeway | Clear space or utility line connection only |
| Additional Insurance | N/A (Basis for other limits) | Additional insurance (does not reduce Cov A) |
The 10% Limit and Valuation Rules
On most standard Homeowners forms (HO-2, HO-3, and HO-5), the limit for Coverage B is automatically set at 10% of the Coverage A limit. For example, if a home is insured for $300,000 under Coverage A, the policy provides $30,000 for Coverage B. It is critical for students to remember that for these forms, Coverage B is additional insurance. This means if a total loss occurs that destroys both the house and a detached shed, the insurer will pay the full Coverage A limit plus the Coverage B limit.
However, note that in the HO-8 (Modified Form), which is used for older homes where replacement cost might significantly exceed market value, Coverage B is often a part of the total limit rather than an additional amount. You can practice identifying these nuances with our practice Homeowners questions.
Regarding valuation, Coverage B typically follows the same rules as Coverage A. If the insured maintains the required percentage of insurance to value (usually 80%), losses to other structures are settled on a Replacement Cost Basis. If the 80% threshold is not met, the insurer may pay the Actual Cash Value (ACV) or a proportion of the replacement cost.
Coverage B Quick Facts
Important Exclusions and Limitations
While Coverage B is broad, there are specific exclusions that frequently appear on the insurance exam. The most significant exclusions involve business use and rentals.
- Business Use: Coverage B does not apply to any structure used in whole or in part for business purposes. For instance, if an insured runs a commercial auto repair shop out of their detached garage, that garage is excluded from Coverage B.
- Storage Exception: There is a narrow exception for business use. If the structure is used solely to store business property (like a contractor storing tools in a shed), and those tools are owned by the insured or a tenant, the structure itself is still covered. The business property inside, however, would be subject to the sub-limits of Coverage C.
- Rentals: Coverage B does not apply to structures rented or held for rental to anyone who is not a tenant of the dwelling. However, an exception exists if the structure is rented solely as a private garage.
- Land: Like Coverage A, Coverage B does not cover the land itself on which the other structures sit.
Exam Strategy: The Breezeway Trap
Watch out for questions describing a garage connected to the house by a roofed breezeway. In the insurance world, a breezeway makes the garage part of the dwelling. Therefore, a garage connected by a breezeway is covered under Coverage A, not Coverage B. Coverage B only applies if there is no physical structural connection (other than a fence or utility line).
