Best locations for building a home tornado shelter?

April 5, 2026

Quick Answer

The best locations for building a home tornado shelter are in a basement, storm cellar, or a specifically designed in-ground shelter, preferably in the center of the house, away from exterior walls and windows.

Choosing the Ideal Location

When selecting a location for your tornado shelter, consider the center of your home, ideally at least 20 feet away from any exterior walls. This reduces the risk of damage from flying debris and collapsing walls. A basement or storm cellar is the most ideal choice, as it’s underground and partially shielded from wind-borne debris.

Design and Construction Considerations

A well-designed and constructed shelter should have a robust foundation, such as a reinforced concrete slab or a reinforced masonry wall. The shelter should be at least 6 feet 8 inches high, wide, and long to accommodate multiple occupants. The doors should be at least 3 inches thick, secured with a heavy-duty latch or a spring-loaded door, and designed to withstand wind pressures of at least 200 pounds per square foot.

Additional Safety Features

Consider incorporating additional safety features, such as a reinforced roof, a self-closing and self-locking door, and a ventilation system. A shelter with a reinforced roof can help prevent collapse from wind-borne debris. A self-closing and self-locking door ensures that occupants can’t be trapped inside. A ventilation system helps to dissipate heat and prevent asphyxiation from carbon monoxide buildup. Always follow local building codes and regulations when designing and constructing your tornado shelter.
