Other Structures Coverage: 10% Rule for Fences and Sheds

By Plain Money Guide · Researched from official sources · Checked 2026-08-11 · Editorial standards

Coverage B pays 10% of your dwelling limit for the fence — the tree that broke it is a separate line.

Your fence, shed and detached garage fall under Coverage B — usually 10% of your dwelling limit, and it's extra money, not carved out of Coverage A.

That single sentence settles most of the arguments people have with adjusters after a summer storm. The rest of the arguments come from a different place: the tree that knocked the fence over is not covered by the same rule, is capped far lower, and on a standard policy is often not covered at all when wind is what felled it. Here is how the two rules stack, with the arithmetic carried through.

What Coverage B actually pays for

Standard homeowners forms — the ISO HO-3 that most carriers build their policy on — split your property into Coverage A (the dwelling), Coverage B (other structures on the residence premises, set apart by clear space), Coverage C (personal property) and Coverage D (loss of use). Coverage B is written at 10% of Coverage A, and in the ISO form it is additional insurance: a $40,000 fence-and-shed loss on a $400,000 dwelling does not shrink the $400,000 available for the house itself.

The "set apart by clear space" test is what decides borderline cases. An attached garage is part of the dwelling and draws on Coverage A. A carport connected only by a fence or utility line is still Coverage B. A detached garage joined to the house by a covered breezeway is usually treated as attached — that call belongs to the adjuster and the policy language, and it matters, because it decides which limit the loss eats into. The Insurance Information Institute summarizes the four coverage parts, and your declarations page lists the actual Coverage B dollar figure your carrier assigned.

The math: what 10% actually buys

Take a $400,000 Coverage A limit, so Coverage B is $40,000. A derecho takes out 180 feet of cedar privacy fence and caves in the shed roof:

• Fence replacement: $9,800
• Shed roof: $4,200
• Total damage: $14,000 — well inside the $40,000 limit
• Flat $2,500 all-perils deductible → carrier pays $11,500

Now change one thing. If the storm was a named hurricane and your policy carries a 2% named-storm deductible, that percentage is applied to Coverage A, not to the size of the loss: 2% of $400,000 = $8,000. Same $14,000 of damage, and the check drops to $6,000. That $5,500 swing has nothing to do with the fence and everything to do with which deductible was triggered.

This is why the 10% limit is rarely the binding constraint on a fence claim. A total loss of every structure on a suburban lot seldom reaches $40,000. The deductible is what decides whether filing is worth it.

Where the tree rule breaks

Homeowners assume the tree and the fence ride on the same coverage. They do not. Trees, shrubs and plants sit in a separate additional coverage capped at 5% of Coverage A, with a $500 maximum per tree, shrub or plant — and unlike the house, they are covered only against a short named-peril list: fire, lightning, explosion, riot, aircraft, a vehicle not owned by a resident, vandalism and theft. Wind, hail and the weight of ice are not on that list in the standard form.

Removal is its own line. Debris removal for a fallen tree pays up to $1,000 per loss, no more than $500 for any one tree, and only when the tree damaged covered property or is blocking a driveway or a ramp built for handicapped access. A 90-foot oak that comes down in the middle of the yard and hits nothing generates zero coverage on a standard policy — not for the tree, not for the $1,800 crane bill to haul it out.

Run the same storm through both rules:

• Oak falls on the fence. Fence damage $6,000 → Coverage B, covered.
• The oak itself → $0, because wind isn't a listed peril for trees.
• Hauling the oak off the fence → $500 (one tree).
• Claim total $6,500, minus a $2,500 deductible → $4,000.

What's damaged	Coverage that pays	Standard limit	Peril catch
Fence, shed, detached garage	Coverage B – Other Structures	10% of Coverage A, additional	Same open perils as the house
The tree, shrub or plant itself	Coverage C additional coverage	5% of Coverage A; $500 per tree	Wind, hail and ice excluded
Hauling away a downed tree	Debris removal	$1,000 per loss; $500 per tree	Only if it hit covered property or blocks a drive
Structure rented to a non-tenant	Not covered under B	$0	Needs a landlord or business endorsement
The land under the structure	Excluded outright	$0	Regrading and fill are on you

Structures the 10% never reaches

Coverage B excludes structures used for business and structures rented to anyone who is not a tenant of the dwelling — with one carve-out: renting a detached structure out solely as a private garage stays covered. So the shed where you store inventory for an online store is outside Coverage B, and so is the backyard cottage you list on a short-term rental site. Both need to be scheduled or endorsed before the loss, not after.

Land is also excluded, which surprises people whose retaining wall failed. The wall may be a covered structure; the soil it was holding back is not, and neither is the excavation and fill needed to rebuild the slope. That gap regularly turns a $9,000 wall claim into a $20,000 project.

Check the loss-settlement basis, not just the limit

A 10% limit tells you the ceiling. The loss-settlement clause tells you what a covered loss is actually worth. Most HO-3 policies settle buildings on a replacement-cost basis, but carriers in wind-exposed states commonly attach an endorsement that carves specific items — fences, awnings, screens, sometimes roof surfacing — down to actual cash value. On a 14-year-old wood fence with a 20-year life, that endorsement can cut a $9,800 claim to roughly $3,000 before the deductible even applies.

Find it by reading the endorsement list on your declarations page for anything with "actual cash value loss settlement" in the title. If you cannot tell, your state insurance department will read the form with you — the NAIC consumer directory links to every state's office, and consumer help lines like the Texas Department of Insurance storm pages handle exactly this question.

FAQ

My neighbor's tree fell on my fence. Doesn't their insurance pay?

Not by default. An act of nature is nobody's fault, so your own Coverage B pays and your own deductible applies. Your carrier can pursue the neighbor only if the tree was already dead or visibly hazardous and the neighbor had been put on notice — which is why a dated photo and a written note to the neighbor about a leaning tree is worth keeping.

Can I raise Coverage B above 10%?

Yes. Carriers sell increased other-structures limits in flat increments, and the premium is small because Coverage B losses are small. It is worth doing if you have a detached garage, a large barn or a pool house whose rebuild cost clearly exceeds 10% of your dwelling limit.

Does a Coverage B claim count against me the same as a house claim?

Yes — it is a paid property claim on your CLUE report either way, and most carriers do not distinguish the coverage part when rating renewals. A $4,000 net recovery on a fence is still a claim on your record for the next five years.

Where the call actually splits

If the only damage is the fence and your deductible is $2,500 or higher: price the repair before you file. A typical 180-foot fence replacement runs under $10,000, and if an actual-cash-value endorsement applies to fences, the net check on an older fence can land near your deductible. A claim that nets $1,000 is not worth five years on your CLUE report.

If a tree came down but hit nothing: do not file. Wind is not a covered peril for the tree, and debris removal only triggers when the tree damages covered property or blocks a driveway. The claim pays $0 and still gets recorded.

If the tree hit the fence, the shed and the house: file one claim, not three. Coverage A, B and C losses from a single storm share one deductible per occurrence — so bundling the $6,000 fence with the $18,000 roof means the $2,500 comes out once, not twice, and Coverage B's 10% is paid on top of the dwelling limit rather than out of it.

If a detached structure is rented out or used for business: the 10% does not apply to it at all, and no post-loss argument fixes that. The endorsement has to be on the policy before the storm.
