Install Comparison
Garage vs Yard Storm Shelter Installation
Where you put a storm shelter matters as much as which type you buy. A garage in-floor unit lets you shelter without going outside, while a yard unit keeps the install out of your living space.
The Short Answer
Should I Put My Storm Shelter in the Garage or the Yard?
A garage in-floor unit is best if you want to shelter without leaving the house, while a yard unit is best if you want to keep the garage clear and have room outside.
Both placements can use a below-grade unit that meets FEMA P-320 and ICC-500, so the protection is the same. The decision is about convenience, lot size, and cost. Garage installs involve cutting the slab, while yard installs involve excavation and grading, and each suits a different home.
Side by Side
Garage vs Yard at a Glance
| Factor | Garage In-Floor | Yard Unit |
|---|---|---|
| Access during a storm | Indoors, no going outside | Walk or drive across the yard |
| Typical cost | $4,000 to $7,500 | $3,000 to $8,000 |
| Space used | One garage bay (park over the lid) | A corner of the yard |
| Install work | Saw-cut and finish the slab | Excavate, set, backfill, grade |
| Best for small lots | Excellent | Limited |
| After-storm exit | Lid must clear of debris | Door at grade in open yard |
Decision Framework
Which Should You Choose?
Choose a garage unit if...
You want to reach the shelter without stepping outside, you have a small lot, or storms in your area often hit overnight. The flush lid lets you park over it and keeps the unit out of sight.
Choose a yard unit if...
You want to keep your garage bay free, you have a larger lot that drains well, or you prefer an above-ground unit placed outside. A yard door at grade is easy to clear after a storm.
Plan the Exit
Think About Getting Out, Not Just In
Whichever placement you choose, confirm you can exit easily after a storm. Garage lids should be spring-assisted or counterbalanced so they open even with some debris on top, and yard doors at grade should sit where falling debris is less likely to trap them. Ask the installer to demonstrate the exit from inside.
Common Questions
Frequently Asked Questions
Can I park over a garage storm shelter?
Yes, in most layouts. A garage in-floor unit has a flush lid at floor level, so you can park directly over it and only need the bay clear when you actually use the shelter. Tell the installer your parking setup so the unit is placed well.
Is a garage shelter as safe as a yard shelter?
Yes, when built to FEMA P-320 and ICC-500. A garage in-floor unit is a below-grade shelter like a yard unit, with the added benefit of indoor access. The protection comes from the same testing and anchoring.
Does cutting the garage slab cause problems?
Not when done correctly. The installer saw-cuts a clean opening, sets the unit, and finishes the surrounding concrete so the floor is sound and the lid sits level. The shelter is designed to integrate with the slab.
What if debris blocks my shelter after a tornado?
Code-rated garage lids are spring-assisted or counterbalanced to open with weight on top, and yard doors sit at grade for easier clearing. Ask the installer to show you how to exit from inside so you are confident after a storm.
