Manufactured homes are about 6% of the American housing stock and account for 54% of tornado housing fatalities.

That single ratio explains why this article exists, and why the guidance operators can actually find is so thin. Search for a mobile home park emergency plan and you get a state agency page and two PDFs written in 2010 and 2011. Meanwhile California requires a plan by statute, Minnesota requires an actual storm shelter for most communities licensed since 1988, California added a rent-abatement statute ten months ago that almost nobody has written about, and FEMA has a policy — in writing — that it will generally not pay to clear destroyed homes from your community because you are a commercial enterprise expected to carry insurance for it.

None of that is hard to comply with. All of it is expensive to discover after the storm.

This guide covers what is actually mandated and where, what the structural exposure looks like by home vintage, how the FEMA funding routes work for a private operator, and what your obligations are once the wind stops.

General information for operators, not legal or engineering advice. Requirements are state and often municipal, and one of the statutes below took effect in January 2026.

Key takeaways

• California mandates an emergency preparedness plan as a condition of the permit to operate — and it must be customised to your community, not a generic booklet.
• Minnesota mandates a physical storm shelter for communities of 10+ homes licensed after 1 March 1988. An evacuation plan is not an alternative.
• We found no other state with a plan mandate. Where shelter requirements exist elsewhere, they are almost always municipal or county code.
• Home vintage decides outcomes. In HUD's Hurricane Charley study, 0% of post-1994 homes suffered structural roof damage, against 64.7% of pre-1976 homes.
• California discharges lot rent during a mandatory evacuation under Civil Code §798.64, effective 1 January 2026.
• FEMA generally will not clear your debris. Its policy names trailer parks specifically as commercial property expected to carry insurance for it.
• A private operator cannot apply for FEMA mitigation funding directly — it flows through state and local government.

Where a plan is actually required

California is the one real mandate. Health & Safety Code §18603(b)(1) provides that "on or before September 1, 2010, an owner or operator of an existing park shall adopt an emergency preparedness plan." New parks must adopt one before the permit to operate issues — and HCD is explicit that the plan "is required in order to receive a permit to operate."

Three duties come with it:

• Post the plan in the clubhouse or another publicly accessible area
• Give annual written notice to every resident on how to access it — including in a language other than English
• Maintain a responsible person reachable by telephone at all times, who must reside on site in parks of 50 or more units

The plan cannot be a generic booklet. HCD's Form MP-250 checklist requires park identification, how residents obtain the plan, maps showing exits and elevation, police and fire contacts, local emergency radio frequencies, the disaster risks specific to your area, household preparedness guidance, state emergency services contacts, and the resident notice itself.

Enforcement runs through inspection and complaint investigation, with violations treated as an unreasonable safety risk correctable within 60 days.

Everywhere else, the answer is mostly no. We searched hard and found no other state statute mandating a written emergency preparedness plan for manufactured housing communities. Indiana comes closest and only encourages operators to remind residents annually about weather radio and smoke detector batteries.

That is not a reason to skip it. It means that outside California, your plan is a liability and insurance question rather than a licensing one — and the absence of a statutory standard cuts both ways when something goes wrong.

Minnesota requires a shelter, not a plan

Minnesota is the outlier worth knowing about because it regulates the physical asset rather than the paperwork. Minn. Stat. §327.20, subd. 1(6)–(8) sets three tiers:

Construction standards sit in §327.205 and Minnesota Rules Chapter 1370, which adopts FEMA P-361 by reference. The only carve-out from the third tier is temporary parks established after a declared disaster, capped at 18 months.

Elsewhere in the tornado belt, shelter requirements exist but at municipal or county level — Iowa has city and county ordinances specifically titled for storm shelters in manufactured home communities. Check your local code, not just your state code. This is one of the few areas in manufactured housing where the binding rule is more often municipal than statutory, and it maps unevenly across the state-by-state landscape.

Wind zones and what your homes can actually take

24 CFR §3280.305 divides the country into three wind zones:

• Zone I — everywhere not otherwise designated. Design load: 15 psf horizontal, 9 psf net roof uplift.
• Zone II — 100 mph basic wind speed. Listed coastal counties in Alabama, Florida, Georgia, Louisiana, Maine, Massachusetts, Mississippi, North Carolina, South Carolina, Texas and Virginia.
• Zone III — 110 mph. Hawaii, coastal Alaska, the territories, and specified coastal counties in Florida, Louisiana and North Carolina.

Zones II and III require engineered design by a licensed engineer or architect. Roof-to-wall strapping, where engineered connectors are not used, must be minimum 0.016-inch steel at 24-inch spacing in Zone II and 16-inch in Zone III.

Anchoring is separate and is where communities most often fail. 24 CFR §3285.401 requires that "the manufactured home must be secured against the wind by use of anchor assembly type installations or by connecting the home to an alternative foundation system," to the loads specified on the home's own data plate, with anchor designs prepared by a registered engineer or architect. The installation mechanics are covered in the moving and installing guide.

Vintage decides outcomes, and the data is stark

HUD studied manufactured home performance after Hurricane Charley. The results by construction era are the single most useful risk-profiling tool an operator has:

Structural roof damage (rating 2 or above): 0% of post-1994 homes, 28.6% of 1976–1994 homes, 64.7% of pre-1976 homes. Structural wall damage: 0%, 11.5%, 53%.

And the qualifier that matters: Charley's wind pressures were only 50% to 75% of the design load for homes built after 13 July 1994, when HUD strengthened the wind standards in response to Hurricane Andrew. Those homes were not tested to their limit. The older ones were destroyed well below it.

The operational implication: your pre-1976 inventory is not merely older, it is categorically different — built before any federal standard existed. If you know your vintage mix by homesite, you know where your losses will concentrate before the storm arrives.

Nobody should shelter in place

This has to be said plainly because operators sometimes get it wrong in their own resident communications.

The National Weather Service's position is unambiguous: a manufactured home "is not a safe place to take shelter during a severe weather event. MOVE TO A SAFER STRUCTURE." Occupants face 15 to 20 times higher mortality risk, and complete destruction is expected at wind speeds roughly 45% lower than for a permanent home.

NOAA's severe storms laboratory put the mortality differential at 22.6 times, or 10.6 times after adjusting for geographic concentration — 191 of 321 residential tornado deaths across a ten-year study period occurred in manufactured homes.

Any plan you publish should tell residents to leave, name where to go, and say how they will be told. A plan that offers shelter-in-place guidance for a severe wind event is worse than no plan.

FEMA: how the money actually flows

Two separate systems, and operators routinely confuse them.

Mitigation funding — before an event. You cannot apply. FEMA's Hazard Mitigation Assistance programmes are open to states, tribes, territories, local governments and, for one programme, private non-profits. A private for-profit community operator is not an eligible applicant or subapplicant.

The route that exists is partnership. FEMA's community safe room guidance confirms that funding "is provided to eligible states, tribes and territories that, in turn, provide the funding to local governments," and that safe rooms have been built in manufactured home parks — noting they "can also be designed for multiple purposes, including community centers for manufactured home parks." Design criteria are FEMA P-361.

So: if you want a safe room funded, the conversation is with your city or county emergency management office, positioning your community as the site. Not with FEMA.

Assistance after an event goes to residents, not to you. FEMA's Individuals and Households Program provides rental assistance, lodging reimbursement, repair funds for owner-occupants, and — when the state requests it — direct temporary housing, including units FEMA purchases or leases.

There is an operator angle here that is worth understanding: a community with vacant, serviceable homesites can become a direct housing site, and FEMA's Multi-Family Lease and Repair option funds repairs to habitable rental units in exchange for housing survivors. If you have empty pads after an event, that is a conversation to have early.

FEMA will not clear your debris

This is the finding most likely to change what an operator does, and it is in writing.

Private property debris removal requires a government applicant to certify legal authority and to obtain a public health determination of immediate threat. And FEMA's policy states that removal from commercial property "is usually not eligible because commercial enterprises are expected to retain insurance that covers debris removal" — a category the fact sheet expressly defines to include "apartments, condominiums, and trailer parks."

Exceptions require FEMA pre-approval and are confined to "very limited, extraordinary circumstances."

Read that against your insurance. After a tornado you may be looking at thirty destroyed homes you do not own, sitting on homesites you cannot re-let, with removal costs running several thousand dollars each — and no public assistance. If your policy does not cover debris removal of resident-owned property, nobody is coming. That is a coverage question to resolve now rather than in a claims call.

Clearing a destroyed but not-abandoned home also runs into title and lienholder issues, which follow the same rules as any abandoned home on a homesite. A storm does not create a shortcut around them.

Rent, and California's new statute

California now discharges rent during an evacuation. Civil Code §798.64, added by SB 610 (Stats. 2025, ch. 547, approved 10 October 2025, effective 1 January 2026), provides that "the homeowner's obligation to pay rent shall be discharged for the period during which the homeowner is required to be evacuated" under a mandatory evacuation order pursuant to a declared disaster. On termination, advance rent must be returned within 21 days.

This is ten months old and I have seen no operator guidance covering it. If you operate in California, it belongs in your financial model and your lot rent process now — an extended wildfire evacuation is a revenue event, not just an operational one.

Florida has nothing equivalent. Chapter 723 contains no rent abatement, evacuation or casualty-habitability provision. Nor does any other state statute we could locate. Outside California, this is governed by your lease and by general contract doctrine.

Your maintenance obligations, however, do not pause. Florida's §723.022 duties — comply with applicable building, housing and health codes, maintain common area buildings and improvements, provide access to common areas, maintain the utility connections and systems you are responsible for — apply with full force in the weeks after an event, when they are hardest to meet.

Rebuilding, and the zoning trap

Two provisions pull in opposite directions.

Florida protects the rebuild. Fla. Stat. §723.041(5) provides that a community "damaged or destroyed due to wind, water, or other natural force may be rebuilt on the same site with the same density as was approved, permitted, and built before." Florida's 2025 hurricane legislation adds post-storm permitting plans and bars local permit fee increases for 180 days after a declared storm.

Elsewhere, destruction can end the use. Most communities operate as legal nonconforming uses, and a common ordinance provision terminates that status where the property is destroyed beyond a threshold. Minnesota's statute uses 50% of estimated market value, after which "any subsequent use... shall be a conforming use" — with a 180-day permit application window for residential property. Municipal versions are often harsher.

So a catastrophic event in a jurisdiction where current zoning does not permit manufactured housing communities can end the asset, not just damage it. If you do not know whether your community is conforming or nonconforming, and what your local destruction threshold is, that is the single highest-value item on this list.

What the plan should contain

Working from California's checklist, which is the only real published standard:

1. Community identification and a site map showing exits, road layout and elevation
2. The specific hazards for your location — wind zone, flood zone, wildfire interface, tornado exposure
3. Evacuation routes and destinations, named, with the instruction to leave rather than shelter in place
4. Local emergency contacts and emergency broadcast frequencies
5. The responsible person, reachable at all times, and how residents reach them
6. How residents receive the plan, with annual notice, in the languages your community actually speaks
7. Utility shutoff locations and procedures — gas, water, electric
8. Vulnerable resident register, maintained with consent
9. Post-event sequence — damage assessment, utility restoration, debris, insurance notification
10. Home vintage and anchoring inventory, so you know where losses will concentrate

Point 10 is the one no template includes and the one that most improves the plan. Everything else is process. That one is data.

What the records have to carry

Almost every item above resolves to something that should already be on a homesite record:

• Home vintage — pre-1976, 1976–1994, post-1994
• Wind zone rating and anchoring documentation per home
• Resident contact details and language preference, for the notice obligation
• Vulnerable resident flags, where consented
• Zoning status and the local destruction threshold at community level
• Plan version, posting date and annual notice date, because in California these are compliance evidence
• Insurance policy detail, including whether debris removal of resident-owned homes is covered

A community that can produce a vintage-and-anchoring inventory in an afternoon has a real plan. One that cannot has a document. The wider record architecture sits in the community operations guide.

How RIOO fits

RIOO is a property management platform built natively on Oracle NetSuite, with the homesite as the record — which is what turns an emergency plan from a posted PDF into something operational.

Home vintage, wind zone, anchoring documentation and resident contact and language preference all sit on the homesite, so the exposure inventory the plan depends on is a report rather than a survey. Community-level attributes — plan version, posting date, annual notice date, zoning status — carry their own dates, which is what makes California's posting and annual-notice duties evidenced rather than assumed.

After an event, damage assessment attaches per homesite in the same ledger as the revenue that homesite produces, so the loss and the recovery are the same record.

See how RIOO handles manufactured housing communities.

Conclusion

Two states regulate this seriously and the rest leave it to you. That is not a reason to do nothing, because the exposure does not depend on whether a statute names it.

Your residents live in structures that account for more than half of tornado housing deaths while making up a sixteenth of the housing stock. Your pre-1976 homes will be destroyed at wind speeds your post-1994 homes will shrug off. FEMA has told you in writing that clearing the wreckage is your insurer's problem. And in a jurisdiction with the wrong zoning ordinance, a bad enough event can end the community's right to exist.

The plan is worth writing. The inventory behind it — vintage, anchoring, zoning status, coverage — is worth more.

Frequently asked questions

Q1. Is a mobile home park emergency plan legally required?
In California, yes — Health & Safety Code §18603 requires one as a condition of the permit to operate, posted publicly with annual written notice to residents. We found no other state with a plan mandate. Minnesota instead mandates a physical storm shelter for most communities of 10 or more homes licensed after March 1988.

Q2. Do I have to provide a storm shelter?
Only where state or local law says so. Minnesota requires an actual shelter for communities of 10+ homes licensed after 1 March 1988, with no evacuation-plan alternative. Elsewhere, shelter requirements are typically municipal or county ordinances, so check local code.

Q3. Can residents shelter in place in a manufactured home?
No. The National Weather Service is explicit that a manufactured home is not a safe place to shelter in severe weather, with occupants facing 15 to 20 times higher mortality risk and destruction expected at wind speeds roughly 45% lower than for a permanent home.

Q4. Will FEMA pay to remove destroyed homes from my community?
Generally no. FEMA policy treats commercial property — expressly including trailer parks — as usually ineligible for private property debris removal, on the basis that commercial enterprises are expected to carry insurance covering it.

Q5. Can I apply for FEMA funding for a safe room?
Not directly. Hazard Mitigation Assistance flows to states, tribes and territories and then to local governments. A private operator's route is to partner with a city or county as the applicant, with the community as the site.

Q6. Do residents still owe lot rent during an evacuation?
In California, no — Civil Code §798.64, effective January 2026, discharges the obligation for the period a resident is under a mandatory evacuation order pursuant to a declared disaster. Florida and other states have no equivalent MH-specific provision.

Q7. Can a destroyed community be rebuilt?
In Florida, yes — §723.041(5) permits rebuilding on the same site at the same density. Elsewhere, if the community is a legal nonconforming use, destruction beyond a threshold — often 50% of value — can terminate that status and require conformity with current zoning.
