Limiting fire and smoke spread relies on compartmentation and fire-resistance of barriers. A fire wall is designed to resist heat and flames for a specified time, keeping the fire contained in its compartment. When you penetrate that wall without proper approval and fire-stopping, you create a direct path for heat, flames, and smoke to move into adjacent spaces. The wall’s protective rating is compromised, so the fire can spread more rapidly through the building.

Installing smoke detectors in kitchen areas is protective, not a path for spread; it helps detect a fire early. Replacing furniture changes the fuel load but doesn’t by itself create a new spread path between compartments. Adding outlets involves electrical work and can be risky, but it doesn’t inherently compromise a fire barrier in the same direct way as penetrating a fire wall with no approved fire-stopping.
