What Is a Casualty Event in Commercial Real Estate?
In commercial real estate, a casualty event refers to physical damage to a property that disrupts its normal use or operations—not to injury or loss of life. It is a technical lease concept focused entirely on the building and the tenant’s ability to function within it.
What May Constitute a Casualty Event?
A casualty event is defined not by the headline or cause, but by whether physical damage materially affects a tenant’s ability to occupy or operate in the space. Common examples include:
-
Fire or smoke damage
-
Wind, hail, or severe storm damage
-
Flooding or water intrusion
-
Structural failure or partial collapse
-
Explosion or impact damage
-
Major mechanical, electrical, or HVAC system failure
-
Government-mandated closures tied directly to property damage
How a Casualty Event Is Handled
-
What happens after a casualty is already spelled out in the lease
-
The lease explains who fixes what, whether rent is reduced, and for how long
-
Once damage occurs, those rules automatically go into effect
Summary: When a casualty happens, the lease sets the rules so there’s no guesswork in the middle of a disruption.
Damage Assessment and Repair Responsibility
-
Ownership determines whether the space is partially usable, unusable, or significantly damaged
-
That determination drives repair timelines and next steps
-
Landlords typically repair the building structure and common areas
-
Tenants are generally responsible for their interiors, equipment, and contents
Summary: The extent of the damage determines how long recovery takes and what options are available to both parties.
Rent Abatement and the Reality of Business Disruption
-
If a tenant cannot operate, rent is typically reduced or paused during the downtime
-
Rent abatement applies only while the space cannot be used
-
Reduced rent does not offset lost revenue or operational disruption
Summary: Rent abatement helps with occupancy costs, but it does not protect the business itself.
Why Tenant Representation Matters—Before a Casualty Ever Occurs
-
Business disruption can cost hundreds of thousands of dollars in lost revenue, downtime, relocation, and inefficiency
-
Standard lease language often favors the landlord and limits tenant flexibility
-
A tenant-representation broker negotiates casualty terms that reflect real business risk
-
These protections must be secured before the lease is signed—after a casualty, leverage is gone
Summary: Casualty risk is not avoided—it is allocated, and strong tenant representation is what protects the business when disruption occurs.
