What Is Excluded Under Coverage B Other Structures?
Structures used for business, rented out, or built on separate land aren't covered, and fences, driveways, and landscaping often have limits.

Business use voids it
If a detached garage or barn gets used for a business, even a small home office with clients visiting, Coverage B often won't pay to repair it. Check your declarations page for how your insurer defines business use before closing.
Rented structures excluded
A guest house or detached unit you rent out to a tenant usually falls outside Coverage B. Insurers treat rental use as a different risk. If you plan to rent any structure on the property, ask about this before you close, not after.
Land matters
Coverage B only applies to structures on the same property as your house. A shed or garage on a separate lot, even one you own, typically isn't covered under this policy. This matters if the property you're buying includes a detached parcel.
Fences and driveways capped
Even when covered, fences, driveways, retaining walls, and landscaping often have their own lower limits inside Coverage B, sometimes a small percentage of your dwelling coverage. If the house has an expensive fence or mature landscaping, check the limit before you assume it's fully covered.
Worth checking before you close
Coverage B limits and exclusions vary by insurer. If this property has a rented unit, a home business, or a detached structure on separate land, comparing policies now shows which one actually covers it.
What else does Coverage B typically leave out
Beyond business use, rentals, and separate land, Coverage B usually excludes structures used for anything other than private, residential purposes tied to the main house. A detached garage you convert into a workshop that produces goods for sale, a barn used to board other people's horses for a fee, or a pool house rented out for events can all fall outside the coverage even if nothing about the building itself changed. The exclusion is about how the structure gets used, not how it looks or what it cost to build.
Structures under construction or not yet finished at the time of a loss are another common gap. If the property you're buying has a detached structure mid-renovation, or one the seller started and never finished, ask whether your insurer treats it as covered from day one or only once it's completed and in normal use. Some policies also exclude structures that have sat vacant or unused for an extended period, which can matter if a shed or old barn on the property hasn't been touched in years.
Coverage B also generally follows the same cause-of-loss rules as your dwelling coverage, so whatever your policy excludes for the house, like flood or earthquake damage, it excludes for other structures too. A detached garage damaged by a flood needs a separate flood policy to be covered, same as the main house. This is worth knowing if the property sits in a flood zone or near a fault line, since the other structures on it carry the same gaps as the home itself.
Finally, some policies cap how much of Coverage B applies to any single structure, even when the total limit looks generous. A detached garage worth more than the standard sublimit for one structure might only be partially covered, with the rest of Coverage B reserved for other structures on the property. If the home you're buying has one large detached structure, like an oversized garage or guest house, rather than several small ones, check whether your insurer applies a per-structure cap in addition to the overall Coverage B limit.
Does Coverage B have its own deductible and claim rules
Coverage B doesn't usually have its own separate deductible. Most policies apply the same deductible from your dwelling coverage to any claim on a detached garage, fence, or shed. If your dwelling deductible is a flat dollar amount, that same number applies to other structures. If your policy uses a percentage deductible for certain perils like wind or hail, that percentage is often calculated off your dwelling limit, not the smaller Coverage B limit, which can make the deductible feel large relative to what the structure is worth.
Filing a claim for a detached structure works the same way as filing one for the house. The insurer sends an adjuster, assesses the damage, and pays out based on your policy's valuation method. Some policies pay the actual cash value of a damaged structure, which factors in depreciation. Others pay replacement cost, meaning what it actually costs to rebuild. A twenty-year-old detached garage valued at actual cash value could get you far less than you'd need to rebuild it. Check your declarations page for which method applies to Coverage B specifically, since some insurers handle it differently than they handle the main dwelling.
One claim on a detached structure can also affect your broader policy the same way a dwelling claim would. A claim for storm damage to a fence or a lightning strike on a shed still counts as a claim on the policy as a whole. It can factor into your renewal pricing or claims history, even though the dollar amount involved is often small compared to a claim on the house itself. Worth asking before closing whether minor Coverage B claims are treated the same as major ones when it comes to future pricing.
If the property you're buying has multiple detached structures, like a shed, a detached garage, and a fence, all three draw from the same overall Coverage B limit rather than each having a separate pool of money. A large claim on one structure can leave less available if something else on the property gets damaged in a separate incident later in the same policy period. Knowing the total limit and how claims draw it down matters more on a property with several structures than one with just a single garage.
Before closing
Look at your declarations page for the Coverage B limit and any per-structure caps, then check how it treats the detached structures on this property, their use, their location, and their valuation method.
