EERO (Emergency Escape and Rescue Opening)
A code-required window in every bedroom large enough for firefighter entry and occupant escape — typically a minimum of 5.7 square feet of clear opening. Container bedrooms must include EERO-compliant windows.
EERO (Emergency Escape and Rescue Opening) in Container Homes

Design Constraints
Container interiors present fixed constraints that shape every layout decision: 7 feet 8 inches of usable width (after insulation), a single entry axis, and limited ceiling height in standard units. Successful container floor plans work within these limits rather than fighting them.
Building Code Compliance
Residential container conversions must meet the same habitability and safety standards as conventionally built homes. This includes minimum room dimensions, ceiling heights, egress requirements, ventilation rates, and fire separation between living spaces. Familiarizing yourself with eero (emergency escape and rescue opening) ensures your design passes inspection.
Practical Tips
Work with the container’s geometry rather than against it. Place wet rooms (kitchen, bathroom) close together to minimize plumbing runs. Use High Cube containers whenever ceiling height is critical. Consider the placement of doors and windows early — cutting openings in steel is significantly more work and cost than framing them in wood.
