Tenant Improvements Coverage
Building policies cover different categories of tenant space improvements depending on lease terms:
Building standard improvements (always covered):
- Basic drywall and paint (standard colors)
- Standard carpet or vinyl composition tile
- Standard ceiling grid and tiles
- Basic lighting fixtures
- Standard doors and hardware
Above-standard improvements (coverage depends on ownership):

| "Improvements become landlord property" | ✓ Covered | Not needed |
| "Tenant owns improvements" | ✗ Not covered | ✓ Required |
| "Tenant owns, landlord owns at lease end" | After lease ends | ✓ During lease |
| Lease silent on ownership | Unclear - risk | Tenant should cover |
Coverage Extensions and Additional Coverages
Standard building policies include several automatic extensions that apply after sprinkler water damage:
Debris removal: Cost to remove water-damaged materials and debris. Usually included as additional coverage or subject to a specific sublimit.
Preservation of property: Reasonable costs to protect property from further damage during emergency.
Fire department service charge: Fees charged by fire department for responding to sprinkler alarm or leak. Subject to policy sublimit.
Pollutant cleanup: Limited coverage for cleanup of substances released due to covered cause of loss. Subject to policy sublimit.
Increased cost of construction: Additional costs to comply with building codes when repairing covered damage. Often requires separate ordinance or law coverage.
Exclusions and Limitations
Building policies exclude certain types of losses even when sprinkler-related:
| Exclusion | What's Excluded | Coverage Alternative |
|---|---|---|
| Tenant contents | All tenant-owned property | Tenant BPP policy |
| Gradual leaks | Slow seepage over time | No coverage (maintenance issue) |
| Wear and tear | Deterioration from age/use | No coverage (maintenance) |
| Faulty workmanship | Cost to redo defective work | Contractor liability or warranty |
| Earthquake | Sprinkler damage from earthquake | Earthquake coverage endorsement |
| Flood | External water entering system | Flood insurance policy |
Valuation and Settlement
Building policies typically provide replacement cost coverage with conditions:
Replacement cost valuation: Pays to repair or replace with materials of like kind and quality without depreciation deduction.
Actual cash value (if replacement not completed): If landlord does not repair within policy time limits, settlement reverts to ACV (replacement cost minus depreciation).
Functional replacement cost: Some policies allow repair with functionally equivalent materials rather than exact match. This can reduce costs for obsolete materials.
Agreed value (optional): Waives coinsurance by locking in building value at policy inception. Prevents coinsurance penalties for underinsurance.
Loss of Rents Coverage
Building policies can include loss of rents (rental income) coverage:
- Pays actual loss of rents when building damage makes spaces unrentable
- Includes fair rental value of owner-occupied spaces
- Covers continuing expenses that must be paid during repairs
- Subject to waiting period
- Limited to period of restoration
This coverage is separate from tenant business income coverage. Both may pay from the same sprinkler leak if both landlord and tenants suffer covered losses.
Does commercial building policy cover tenant build-out costs?
It depends on ownership. Building standard improvements in all suites are covered. Above-standard tenant improvements are covered only if the lease makes them landlord property. If tenant owns improvements, tenant BPP must cover them.
Does commercial building policy cover outdoor property damaged by sprinkler leak?
Limited coverage applies. Outdoor property near the building may be covered up to a sublimit. Parking lots, landscaping, and detached structures may require separate coverage or endorsements.
