What Counts as a Detached Structure?
A detached garage, shed, fence, or standalone deck all count. These fall under Other Structures coverage, separate from your house.

What Your Policy Lists
Your declarations page shows a dollar amount for Other Structures coverage. That number is a limit, not a guarantee it matches what's on the property. Check it against the garage, shed, or fence you're actually buying before you close.
Attached vs Detached
A garage sharing a wall or roofline with the house falls under dwelling coverage, not Other Structures. The distinction matters because dwelling limits are usually much higher. If the seller's disclosure mentions a breezeway connecting two structures, ask whether that counts as attached.
How the Limit Gets Set
Other Structures coverage is often set as a share of your dwelling coverage unless you ask to change it. A detached three-car garage or a guest house can cost more to rebuild than that default limit allows. Walk the property and compare what's there to the number on the page.
What the Lender Cares About
Lenders focused on a binder before closing usually check that dwelling coverage matches the loan amount. Other Structures coverage rarely gets the same scrutiny. That leaves it to you to confirm sheds, fences, or detached garages are valued correctly before you sign.
The Other Structures limit on a quote was set by a formula, not by what's actually on the property. If the detached garage or guest house would cost more to rebuild than that number allows, the gap comes out of your pocket after a loss. Comparing quotes now is the chance to set that limit correctly before closing, while it's still easy to fix.
Does a Pool, Driveway, or Mailbox Count?
Other Structures coverage isn't only for buildings. A swimming pool, a paved driveway, a mailbox, a retaining wall, even a flagpole can fall under the same coverage as the detached garage or shed. Anything on the property that isn't the house itself and isn't attached to it usually gets grouped here, whether or not it has four walls and a roof.
Pools make this matter most. An in-ground pool is expensive to repair or replace, and if one sits on the property, it draws from the same Other Structures limit as everything else outside the house. A shed, a fence, and a pool can all be competing for coverage under one number on the declarations page. If that number was set as a default share of dwelling coverage, a pool alone might use up most of it, leaving little for the rest.
Landscaping is usually treated differently and often excluded or capped on its own. A mature tree or a retaining wall built into a slope may not be covered the way a fence is. The seller's disclosure or a walk-through with the inspector is the place to find out what's actually sitting on the land. Matching that list against what the policy covers, item by item, is the only way to know if the limit is enough.
Some of these structures carry their own risk beyond property damage. A pool can affect liability coverage too, since it changes what might happen on the premises. If the house has a pool, a detached garage, and a fence, it's worth asking directly whether all three are accounted for in the quote, and at what value, rather than assuming one limit stretches to cover all of it.
What If a Structure Gets Damaged or Destroyed?
A claim on a detached garage or shed works differently than one on the house. The Other Structures limit pays out for repair or rebuild, but it's a separate pool of money from dwelling coverage. If a storm takes down a fence and damages the roof at the same time, two different limits are paying for two different repairs, not one combined check.
The deductible usually applies once per claim, not once per structure. If wind damages the house and the detached garage in the same event, most policies treat that as a single claim with a single deductible, not two. But if the garage burns down in an unrelated fire six months later, that's a separate claim with its own deductible. Reading how the policy defines a single occurrence matters more than people expect.
Older detached structures raise their own questions. A garage built decades before the house was bought might not meet current building codes, and some policies pay to rebuild to code while others pay only to restore what was there. If the property has an older shed, barn, or garage, it's worth asking whether the quote includes coverage for code upgrades, since that gap can be expensive to discover after a loss rather than before.
Underinsuring a detached structure doesn't just risk a shortfall. Some insurers apply a coinsurance penalty, reducing the payout proportionally if the structure was insured for less than what it would actually cost to rebuild. A shed or garage valued too low on the declarations page can mean a smaller check than expected, even for damage that's otherwise a covered loss. Confirming the rebuild cost before closing, not just the limit, is what avoids that outcome.
Before You Close
Walk the property and list every shed, fence, garage, or pool that isn't attached to the house. Compare that list against the Other Structures number on any quote before you sign.
