A safe room should be designed around the building and the hazard.
A protected space is not one universal product. Existing basements, interior rooms, new construction and detached structures all have different feasibility and safety requirements.
The location matters
Flood exposure, groundwater, structure, egress, fire safety, ventilation, access and local requirements can make one protected-space concept appropriate and another unsuitable.
Protection is more than walls
A useful protected space may depend on clean air, backup power, water, sanitation, communications and safe access. Those systems should be coordinated rather than added independently.
Professional verification is essential
Structural and life-safety decisions require applicable qualified professionals. SASNA can organize the planning logic, but it does not automatically certify a room or structure as safe.
Frequently asked questions
Can an existing basement become a safe room?
Sometimes. Feasibility depends on the structure, flood and groundwater conditions, egress, ventilation and other site-specific factors that require verification.
What if my house has no basement?
Depending on the property, options can include an interior protected room, an above-ground hardened room, a detached protected structure or resilience improvements to the whole home.
Does SASNA certify safe rooms?
No. SASNA provides planning guidance and coordinates requirements; applicable engineering, code and life-safety verification must come from qualified professionals.
