What Is Covered Under Coverage B Other Structures?
Detached structures on your property, like a garage, fence, shed, or detached deck, not your house itself.
Free to compare
Coverage B is usually a percentage of your dwelling coverage, shown as its own line on the declarations page that comes with your binder. Before closing, check that number against what is actually on the property. Look at the listing photos or inspection report for a detached garage, a shed, a fence, anything standing apart from the house. Compare its rebuild cost to the Coverage B limit. If the limit looks low for what is out there, ask about raising it now, since you cannot change it after something is damaged.
Check Coverage B before you lock in the binder
Every insurer sets this limit differently, usually a fixed percentage of your dwelling coverage. If that percentage leaves the garage or fence underinsured, comparing policies now is the only way to catch it before closing.
How much does Coverage B actually pay out
Coverage B pays to repair or rebuild the structure, not to replace it with something better. If the fence was ten years old and worn, the insurer pays what it costs to rebuild a comparable fence, not a new upgraded one, unless your policy includes replacement cost coverage on other structures specifically. Check your declarations page for which one you have, since this changes what a payout actually covers.
A detached garage used for storage is treated differently from one rented out or used for a business. Most policies limit or exclude coverage for structures used to run a business, even a small one like a home salon in a detached studio. If the inspection report mentions a structure with any commercial use, ask whether it falls under Coverage B at all or needs a separate endorsement.
The deductible on Coverage B is usually the same one that applies to your dwelling coverage, not a separate number. If a storm takes down both a fence section and part of the roof, you likely pay one deductible total, not one for each. But some policies do split them out, so this is worth confirming rather than assuming before closing.
Coverage B does not extend to detached structures you add after the policy starts, like a shed bought next spring, unless you update the policy to reflect it. A new detached structure raises the total value at risk on the property, and if the Coverage B limit does not move with it, the gap shows up only when there is a claim. Once you close, treat any new structure as something to report, the same way you would report a renovation that changes the house itself.
What counts as a structure under Coverage B
Coverage B applies to things that are not attached to the house and not enclosed by it. A detached garage qualifies. A carport attached to the side of the house usually does not, since it's considered part of the dwelling itself and falls under Coverage A instead. The line between the two is physical attachment, not how the structure is used or how far it sits from the house.
Fences, mailboxes, driveways, and in-ground pools are often covered under Coverage B, but not always to the same degree. Some policies cap payouts on specific categories, like fencing or pools, well below the overall Coverage B limit, even if the stated limit looks like enough on paper. The declarations page may show one number for Coverage B as a whole, while a separate section of the policy, often called special limits or sub-limits, caps what gets paid for certain types of structures. Before closing, it's worth asking whether anything on the property, a pool, a dock, a detached shed used for anything other than storage, falls under one of these caps rather than the full limit.
Land improvements like a paved driveway or a retaining wall sometimes fall outside Coverage B entirely, depending on the insurer. These are often treated as part of the land rather than a structure, which means damage to them might not be covered under this section of the policy at all. If the property has a retaining wall holding up a slope, or an extensive paved area, that's worth asking about directly rather than assuming it falls under the same coverage as a shed or fence.
Trees, plants, and shrubs are not structures, but they sometimes show up under a different part of the same section, with their own small limit, usually a modest dollar amount per item and a lower cap overall. This matters if the property has mature landscaping as part of its value. It's a different kind of coverage than what pays to rebuild a garage, and it's worth knowing the two are not the same before assuming storm damage to a tree is handled the same way as damage to a fence.
Before the binder is final
Pull up the listing photos one more time and count what's standing apart from the house. Match each one against the Coverage B limit and any sub-limits on the declarations page. That's the number worth confirming before closing, not after.
