Safe rooms and backyard shelters: plan before you buy

Begin with your current household plan.

Know where to go for the hazards in your area and how to receive official alerts. A designated interior room is not automatically an engineered storm safe room. Adding a bunker does not remove the need to leave when officials order evacuation. Start with your household plan and National Weather Service tornado guidance.

Have the property assessed before choosing a structure.

• Ask local building and floodplain officials about the property, flood and storm-surge exposure, setbacks and approvals.
• Have a qualified design professional assess soil, groundwater, drainage, structural loads and access. This is especially relevant to coastal and low-lying properties.
• Include everyone who must reach and use the shelter: mobility needs, stairs, door operation, pets and space requirements.
• Ask how people exit if the primary access is blocked and how responders locate them.
• For enclosed or underground occupancy, obtain a professional plan for ventilation, sanitation, water, power and maintenance.

Questions for a storm safe-room supplier.

Ask which current design criteria and local requirements the exact proposed installation meets. Have your design professional review documentation for the room, door assembly, foundation and anchorage together. Request relevant test reports and installation inspection details. A marketing label or strong door alone does not establish the protection of the entire room.

Use FEMA’s safe-room resources as a starting resource for your professional consultation. This guide does not certify a design or provide construction specifications.

Companies do offer backyard bunker projects.

Atlas Survival Shelters (opens in a new tab) is one manufacturer offering shelter plans and custom bunker options. Its website is a research starting point; we have not inspected its products, verified suitability for your property or established an affiliate partnership.

Ask any provider to separate the structure from excavation, delivery, crane access, engineering, approvals, installation, utilities, drainage, ventilation and ongoing service. Request local references and the exact scope of the warranty. Have an independent qualified professional review the proposal before signing.

Choose the smallest project that solves your actual need.

For many households, the next useful investment is an accessible plan, reliable alarms or better outage supplies. A permanent shelter is a specialist project for a defined need and suitable site. Compare that project with improvements to your existing home and access to an appropriate community shelter.
