The problem
Florida's mobile-home mold crisis.
Florida is the nation's #2 most mold-prone state, behind only Louisiana — and mobile homes are the most vulnerable housing type. Wood and drywall absorb water; mold colonies start within 24–48 hours of flooding. We built BioBox to solve this entirely.

"The floor is coming up. Mold is terrible. My doctor told me to move."
— Jacksonville mobile home resident, News4Jax 2025
Half of Florida mobile homes were built before the mid-1980s. Median rent in FL is $1,555/mo — residents can't just leave.

Frequently asked
Mobile home questions.
Why are mobile homes so vulnerable to mold? +
Conventional mobile homes are built with wood framing, drywall, and synthetic vapor barriers. Wood absorbs water; drywall absorbs ~3% of its weight in moisture; mold colonies start within 24–48 hours of flooding. Combined with sealed manufactured construction (poor ventilation), Florida's humidity becomes a chronic mold trap. BioBox uses steel and inorganic materials that simply can't host mold.
Is a BioBox mobile home actually classified as a mobile home? +
Yes — BioBox mobile units are HUD-code-compliant manufactured housing, Florida-approved for mobile-home park placement, residential lots, and rural acreage. We just build them with structural and material specs typically reserved for high-end luxury construction.
Will it survive a Cat 5 hurricane? +
Yes. The steel frame is rated to 200+ MPH winds — that's beyond Cat 5. The fiberglass sheathing is FEMA-certified shelter material, the same spec used for designated disaster shelters. No steel-framed home on record has ever been damaged by wind.
What does $140/sq ft include? +
Move-in ready: MgO panels, impact-rated windows and doors, roofing, electrical, plumbing, HVAC, flooring, cabinetry, fixtures. Transparent cost breakdowns, no surprise change orders. Site prep, foundation, delivery, and permitting are quoted separately based on your lot.
How long until delivery? +
Factory-built units ship 60–90 days from order. On-site assembly is days, not months. Total: typically 90–120 days from contract to move-in.
