Community storm shelters for parks, churches, employers and HOAs

We build storm shelters for groups: manufactured-home communities, churches, small employers, HOAs and campgrounds around St. Louis. A community shelter is designed to FEMA P-361 and ICC 500 criteria for its occupancy, with more space per person than a home safe room and access planned for everyone who'll use it. It's also the kind of shelter SEMA currently administers federal hazard mitigation money for, alongside school safe rooms: the Hazard Mitigation Grant Program pays up to 75% of eligible costs for projects sponsored by eligible applicants like cities, counties and school districts, through the State Emergency Management Agency.

Who needs a community shelter

Manufactured-home communities. The National Weather Service says a mobile home is not safe in a tornado. Residents need somewhere sturdy to go — and in parts of our area, a lot of residents need it: about 9% of housing units in Jefferson County and Franklin County are mobile homes (Census, 2020–2024). We found no Missouri rule requiring parks to provide a shelter; in practice it falls to owners and local governments.

Churches and schools. Congregations and classrooms gather at fixed times. A shelter sized for them protects people who'd otherwise be in a large open room.

Small employers. Warehouses and shops with large open spans and few interior walls. The December 2021 Edwardsville tornado, which collapsed part of a warehouse and killed six, is the region's reminder.

HOAs and campgrounds. Pools, clubhouses and campsites put people outdoors or in light buildings.

What makes a community shelter different from a home safe room

• Occupancy and space. FEMA's grant guidance uses more floor area per person outside one- and two-family homes — 5 square feet per person for other residential tornado safe rooms, versus 3 in a home — and community shelters plan for wheelchairs and people who can't stand.
• Access. Everyone must be able to get in quickly from where they'll be. That decides location, number of doors and paths.
• Ventilation, sanitation, lighting sized for the occupancy and duration.
• Signage and an operations plan — who unlocks it, when, and how residents know.
• Design by an engineer to FEMA P-361 and ICC 500 criteria, with documentation for the permit and, if grant-funded, for FEMA.

Paying for it: how safe room money works in Missouri

Missouri's State Emergency Management Agency says the state "only administers safe rooms for Communities and School Districts" and doesn't fund individual residents. The money comes through federal mitigation programs:

• Who applies. SEMA says applications generally must come from an eligible city, county, special district, public school, university or community college; a county or community may apply on behalf of a private school. Jurisdictions need a current hazard mitigation plan.
• Cost share. HMGP projects are 75% federal and 25% non-federal.
• Track record. SEMA's project list (updated April 2026) shows roughly 280 safe room projects statewide. St. Louis–area examples include school safe rooms in the Rockwood, Orchard Farm, Lincoln County (Troy), Northwest (High Ridge) and Dunklin (Pevely) districts, and a community safe room in the City of Truesdale in Warren County.

For a manufactured-home community, church or employer, that means the path to grant money runs through your city or county: a local government sponsors the project, and the property owner usually contributes the non-federal share and agrees to public access terms. Ask your county's emergency management office whether it's preparing applications; after a federal disaster declaration such as FEMA-4877-DR for the May 2025 storms, mitigation funding becomes available to the state for eligible projects.

If a grant isn't realistic, a privately funded community shelter is still a straightforward building project.

Our process for a community shelter

1. Needs assessment. Who will use it, how many, how fast they need to get there, and accessibility needs.
2. Site selection. Out of flood hazard areas, close to the people it serves, reachable at night.
3. Concept and budget. Prefabricated units, a precast building, or a cast-in-place room within a new or existing building.
4. Funding path. Private, or with a local government sponsor for HMGP.
5. Engineering and permits.
6. Construction and commissioning.
7. Operations plan. Unlocking, signage, drills, maintenance.

Illinois

For Madison, St. Clair and Monroe county properties, Illinois runs its own mitigation programs through the state emergency management agency. We haven't confirmed whether Illinois requires shelters in manufactured-home communities, and we'll check before advising an Illinois park owner.

Our installation crew is a Missouri construction contractor that installs storm shelters as a dedicated part of its business.

Boards and owners who want the background before a meeting can share the complete St. Louis storm shelter guide and, for parks, our page on mobile home tornado safety.

Frequently asked questions

Can a mobile-home park owner apply to FEMA directly? In Missouri, generally no — applications come through eligible local governments and similar entities. Talk to your county's emergency management office.

How big should a community shelter be? Sized for everyone it's meant to serve at the design density, plus accessibility space. An engineer sets the final number.

Who opens it during a warning? That's part of the operations plan — automatic unlocking on a warning, multiple keyholders, or both.

Can an existing building be retrofitted? Sometimes a room within a building can be hardened to the criteria. An engineer's assessment decides it.
