Keep exits clear, alarms operational and garage-to-house door closed.
Home system
Fire safety during renovation
Preserve separations, egress, alarms and garage protection when walls/ceilings are opened or altered.
Checked: 2026-08-21
Any penetration, door or new sleeping room can affect separation or egress requirements.
Unknown fire separation, added suite, garage alteration or combustion appliance: confirm regulatory details before enclosure.
Useful tools and measurements
- Map of affected walls/ceilings
- Photos before enclosure
- Appropriate smoke/CO alarms
- Firestop product documentation
Having a tool does not make regulated work DIY.
What the professional checks
- Identify required separations and ratings
- Detail penetrations and firestop systems
- Check egress, doors, alarms and garage

Requirements vary with the building, jurisdiction, code edition and exact scope. This triage does not replace plans, calculations, permits, inspections or required professionals.
