Pros: Lowest cost. Doesn't take living space. Slightly higher survival rates statistically.
Cons: Not accessible to disabled or mobility-impaired. Can flood in some conditions. Requires yard/garage excavation.
Pros: Accessible. No excavation. Can be used as closet/pantry between events. FEMA-tested to withstand 250+ mph winds and debris impact.

The FEMA P-320 standard specifies design requirements for residential safe rooms. Certified shelters must withstand:
The ICC-500 standard covers commercial and community shelters. Both standards were developed after the 1999 Bridge Creek–Moore F5 disaster.

A $6,000 shelter that lasts 30 years costs $200/year or $16.67/month — less than most streaming service bundles. For a family in a tornado-prone area, this is one of the highest-return safety investments possible.
Alternatively: consider that Joplin 2011 killed 158 people, and post-event studies found that every person killed in a wood-frame home would have survived in a FEMA-rated safe room. That's the value.
