Mixed-Use Building Insurance in California
Commercial property and liability insurance for buildings that combine retail, office, and residential occupancies under one roof, addressing the layered exposures created when different uses share a single structure.

Common Risks & Exposures for Mixed-Use Building
- Fire or liability exposure from a ground-floor retail or restaurant tenant affecting residential units above
- Water damage traveling between commercial and residential floors
- Slip-and-fall injuries in shared lobbies, stairwells, and entryways used by all occupancy types
- Overlapping property and liability considerations across multiple use types
- Loss of rental income across both commercial and residential tenants after a covered loss
- Lender and lease requirements that differ between the commercial and residential portions

Coverage Options for Mixed-Use Building
Mixed-use buildings require underwriter review depending on the occupancy mix. Predominantly residential buildings with ground-floor retail are a common eligible pattern; a higher percentage of restaurant or industrial-type tenants may require additional review.
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.
Umbrella
Adds an extra layer of liability protection above your GL, auto, and employer's liability limits for catastrophic claims.
