Office Building Insurance in California
Commercial property and liability insurance for owners and landlords of office buildings, professional office parks, and multi-tenant office properties, built around the day-to-day risks of leasing space to businesses and their employees and visitors.

Common Risks & Exposures for Office Building
- Fire or electrical damage originating in a tenant suite or shared equipment room
- Slip-and-fall injuries in lobbies, stairwells, elevators, or parking areas
- Water damage from a burst pipe, roof leak, or HVAC condensate line affecting multiple tenants
- HVAC, elevator, or boiler equipment breakdown disrupting the whole building
- Loss of rental income while a covered loss is repaired
- Lender or lease requirements for specific coverage limits or mortgagee wording

Coverage Options for Office Building
Office buildings are a moderate Travelers appetite. Buildings over 15 years old, buildings with significant deferred maintenance, or buildings with a mixed tenant roll that includes higher-hazard occupancies may require underwriter referral.
Commercial Property
Covers your building, contents, and business personal property against fire, theft, and other covered perils.
General Liability
Protects against third-party claims of bodily injury, property damage, and advertising injury arising from your operations — the foundation of most commercial policies.
Business Income
Replaces lost income and covers continuing expenses if a covered property loss forces you to suspend operations.
Equipment Breakdown
May help address certain covered mechanical or electrical failures — from refrigeration, espresso machines, and POS terminals to HVAC, elevators, boilers, and other building systems.
Umbrella
Adds an extra layer of liability protection above your GL, auto, and employer's liability limits for catastrophic claims.
