How One Leak Creates Multiple Claims
A sprinkler leak can damage both building and tenant property simultaneously. Example scenario:
- Corroded riser pipe leaks on third floor
- Water damages ceiling and walls (building property)
- Water damages tenant inventory below (tenant property)
- Water damages second-floor tenant suite (second tenant property)
This creates three separate insurance claims: one landlord building claim, and two separate tenant BPP claims (one per affected tenant).
| Claimant | Policy Type | Covered Loss | Deductible |
|---|---|---|---|
| Landlord | Building policy | Pipe, walls, ceilings (all floors) | Landlord's deductible |
| Third-floor tenant | Tenant BPP | Inventory, furniture, equipment | Tenant's deductible |
| Second-floor tenant | Tenant BPP | Inventory, furniture, equipment | Tenant's deductible |
Independent Deductibles
Each policy has its own deductible. These do not offset or combine:
Landlord building deductible: Varies depending on property value and premium. Applied once per occurrence regardless of how many suites are affected.
Tenant BPP deductible: Varies depending on coverage limits. Each tenant pays their own deductible.
In a multi-tenant building with one leak affecting five suites, there will be one landlord deductible and five separate tenant deductibles.
Coordination of Benefits
Commercial property policies do not coordinate benefits with each other. There is no "primary" or "secondary" coverage. Each policy independently covers its own property.
This differs from liability insurance where multiple policies may cover the same claim. Property insurance follows property ownership, creating clear coverage boundaries.
Coinsurance and Coverage Limits
Building policies often include coinsurance clauses requiring insurance to value. If underinsured, the landlord may face a coinsurance penalty that reduces claim payment.
Tenant BPP policies have scheduled limits for different property categories. If contents value exceeds the policy limit, the tenant bears the excess loss.
| Coverage Issue | Building Policy | Tenant Policy |
|---|---|---|
| Underinsurance penalty | Coinsurance clause applies | Loss exceeds limit = no payment |
| Replacement cost settlement | Usually included for building | May require endorsement |
| Agreed value option | Available for building | Rarely available for contents |
Business Interruption Coverage
Business income (interruption) coverage can be added to both building and tenant policies:
Landlord loss of rents: Pays landlord's lost rental income when building damage makes suites unrentable. Requires direct physical loss to insured building.
Tenant business income: Pays tenant's lost revenue when property damage suspends operations. Requires direct physical loss to insured tenant property.
These are separate coverages with separate waiting periods and benefit periods.
Can one sprinkler leak trigger claims on both building and tenant policies?
Yes. A single leak can cause building damage (landlord's claim) and tenant contents damage (tenant's claim). These are separate losses under separate policies.
Do landlord and tenant share one deductible for sprinkler leak damage?
No. Each party pays their own policy deductible. Landlord pays building policy deductible, each affected tenant pays their own BPP deductible.
