Fire Wall
Definition and meaning of Fire Wall in real estate.
A fire wall is a fire-resistant wall structure designed to prevent the spread of fire between different sections of a building or adjacent properties.
In more detail
These structures are commonly built in multi-family housing, townhouses, and commercial buildings. Constructed from non-combustible materials like concrete, brick, or gypsum board, they must extend from the foundation through the roof to block flames and heat. Building codes require these barriers to meet specific hourly fire-resistance ratings to protect residents and property.

Frequently asked questions
Can you cut holes or run wiring through a fire wall?
Any penetrations for pipes or wires must be sealed with specialized firestop materials to maintain the wall's integrity.
How does a fire wall differ from a fire barrier?
A fire wall is structurally independent, meaning it will stand even if the structure on one side collapses, whereas a fire barrier is not.
