Final answer:
A fire rating is required between demising partition walls between tenants in commercial buildings. The specific fire rating required depends on the building codes and regulations of the specific jurisdiction.
Step-by-step explanation:
In commercial buildings, a fire rating is required between demising partition walls between tenants. The fire rating refers to the amount of time the partition walls can withstand fire before it spreads to adjacent spaces. The specific fire rating required depends on the building codes and regulations of the specific jurisdiction.
For example, in the United States, the International Building Code (IBC) mandates different fire ratings for various types of occupancy and construction. Common fire ratings for demising partition walls range from 1-hour to 2-hour. This means the walls can withstand fire for either 1 or 2 hours, respectively, before it can spread to adjacent spaces.
It's important for landlords, tenants, and architects to consult the local building codes to determine the specific fire rating requirements for demising partition walls between tenants.
