Florida HO-7 Insurance Guide
Does Insurance Cover Water Damage in a Mobile Home in Florida?
Florida HO-7 mobile home policies cover sudden supply line failures, burst pipes, and AC overflow — but exclude gradual leaks, flooding, and pipe replacement. OSB belly wrap entry, polybutylene pipe damage, Citizens $10k mold sublimit, and NFIP foundation requirements explained for Florida manufactured homes.
Florida HO-7 Water Damage — 6 Rules to Know
Sudden = Covered
Burst pipe, sudden supply line failure, AC overflow — sudden and accidental is the covered trigger under HO-7.
Gradual = Excluded
Slow drip, seepage, long-term moisture infiltration — gradual deterioration is excluded regardless of when discovered.
Belly Wrap = Coverage A
OSB belly wrap cut, wet insulation removal, cavity drying, and reseal from a covered event = Coverage A structural scope, not mold remediation. No $10k sublimit.
PB Pipe Damage = Covered
Polybutylene fitting failure water damage is a covered sudden loss. The pipe replacement itself is excluded — not the resulting water damage.
Citizens $10k Mold Sublimit
Citizens HO-7 carries the same $10,000 MRSR mold treatment sublimit as HO-3. Structural drying and flooring = Coverage A, no cap.
NFIP Requires Permanent Foundation
NFIP building coverage for manufactured homes requires a permanent foundation. Park homes on temporary piers may qualify for contents only.
Florida HO-7 Water Damage Coverage — What's Covered vs. Excluded
| Damage Scenario | HO-7 Coverage | Key Rule |
|---|---|---|
| Burst supply line (copper, PEX, CPVC) — sudden failure | COVERED | Sudden and accidental = Coverage A |
| Polybutylene fitting fracture water damage | COVERED | Damage covered; pipe replacement excluded |
| AC condensate overflow — pan or drain line failure | COVERED | Sudden mechanical overflow = covered peril |
| OSB belly wrap damage from covered water event | COVERED | Coverage A; belly cut + insulation removal + reseal covered |
| Wet belly insulation removal and cavity drying | COVERED | Structural scope — not MRSR mold treatment; no $10k sublimit |
| Mold treatment following covered water loss | PARTIAL | Citizens HO-7: $10,000 MRSR sublimit; same as HO-3 |
| Gradual seepage, slow drip, long-term moisture | EXCLUDED | Gradual deterioration exclusion regardless of discovery date |
| Flood from storm surge, heavy rain, or rising water | EXCLUDED | Standard HO-7 excludes all flood; NFIP required |
| Pipe replacement cost (PB, copper, CPVC, galvanized) | EXCLUDED | The broken part — not the damage it caused — is maintenance |
| Park-owned infrastructure failure (pad utilities) | EXCLUDED | Park owner general liability; HO-7 covers internal plumbing only |
| Manufactured home vacancy 30–60+ days (Citizens) | PARTIAL | Citizens HO-7 vacancy provisions; seasonal absence risk |
| NFIP building coverage — permanent foundation required | PARTIAL | Park homes on temporary piers: contents only; verify with carrier |
Florida HO-7 Mobile Home Rules — 4 Critical Points
OSB Belly Wrap Scope Is Coverage A — Not MRSR
The most important scope distinction in manufactured home water restoration: OSB belly wrap entry, wet insulation removal from the floor cavity, cavity drying, and vapor barrier resealing are structural demolition and restoration — Coverage A of your HO-7 with no dollar sublimit. This scope is not classified as mold remediation even if mold is present in the cavity. Only the MRSR-licensed mold treatment itself (antimicrobial application, air scrubbing, clearance testing) counts against the Citizens $10,000 MRSR sublimit. A typical belly entry scope runs $500–$2,000 for structural work before any mold treatment is needed — and adjusters who try to apply the $10k cap to the belly structural scope should be contested with itemized invoices separating structural from mold treatment line items.
Polybutylene Pipe: Damage Covered, Pipe Excluded
Polybutylene (PB) pipe was installed in manufactured homes from approximately 1978–1995. Chlorine in Florida municipal water systems degrades PB from the inside out, eventually causing fittings to crack and fail suddenly. Florida HO-7 covers the resulting water damage — soaked flooring, wet belly insulation, damaged drywall — because the fitting fracture is sudden and accidental. The polybutylene pipe replacement itself is excluded as maintenance and the cost of the broken part. Adjuster argument to watch: 'the loss was expected because PB has known failure risk.' Florida case law generally requires that the specific loss event was expected, not that the category of pipe can fail. Document the specific fracture date, get a plumber's report identifying the exact fitting failure, and push back on any gradual damage characterization.
Citizens HO-7 Vacancy Provisions
Citizens HO-7 manufactured home policies include vacancy provisions similar to HO-3: coverage may be suspended or reduced if the home is unoccupied for 30–60 days depending on policy form. Florida has a large seasonal manufactured home population — particularly in retirement communities — where owners return to northern states from May through October, leaving the home vacant during peak hurricane and thunderstorm season. If water damage is discovered after a prolonged absence, the adjuster may invoke the vacancy provision to deny or limit coverage. Review your Citizens HO-7 policy's vacancy clause before seasonal departure and consider a property manager check-in arrangement to establish habitation continuity.
NFIP and Manufactured Homes: Foundation Is Everything
NFIP flood insurance building coverage for manufactured homes requires a permanent foundation as defined by FEMA — the home must be anchored to the ground with a foundation system meeting local codes. Many Florida manufactured home park residents assume they have NFIP building coverage but actually qualify only for contents coverage because their home sits on temporary piers or blocks without a certified permanent foundation. This distinction is critical in flood-zone parks near rivers, bays, and coastal areas. Check your NFIP declarations page and verify whether it specifies 'building' or 'contents' coverage. If your park home is in Zone AE or Zone X500 and you don't have building coverage, explore whether retrofitting to a qualifying foundation is feasible before the next storm season.
Florida Mobile Home Water Damage Insurance — FAQ
Does HO-7 insurance cover water damage in a Florida mobile home?
Yes — Florida HO-7 covers sudden and accidental water damage from burst pipes, sudden supply line failures, and AC overflow. Gradual leaks, seepage, and flooding are excluded. The Citizens HO-7 policy carries the same $10,000 MRSR mold remediation sublimit as HO-3, but structural drying, belly wrap repair, and flooring replacement are Coverage A with no sublimit.
Is OSB belly wrap floor damage covered under HO-7?
Yes — if the belly wrap damage results from a covered sudden event (burst pipe, supply line failure), the entire belly entry scope is Coverage A: cutting the belly wrap, removing wet insulation from the floor cavity, drying the cavity, and resealing with new vapor barrier. This scope is NOT mold remediation and is not subject to the Citizens $10,000 MRSR sublimit. Insulation removal and replacement is structural demolition, not mold treatment.
Are polybutylene pipes covered under Florida HO-7?
The damage from a sudden polybutylene fitting failure is covered under HO-7. The water damage — soaked flooring, wet insulation, damaged drywall — is a covered sudden and accidental loss. However, the polybutylene pipe itself and the cost of replacement plumbing are excluded as maintenance and the cost of the broken part. If the adjuster argues that PB pipe's known failure rate makes the loss 'expected,' document the specific fitting fracture date and push back — Florida courts generally require the specific loss event to have been expected, not the category of pipe.
Does NFIP flood insurance cover manufactured homes in Florida?
NFIP building coverage requires that the manufactured home be on a permanent foundation (anchored to the ground with foundation system). Manufactured homes in flood-zone parks on temporary piers without a FEMA-compliant permanent foundation may not qualify for NFIP building coverage — only contents coverage. Before storm season, verify with your NFIP carrier whether your home meets the permanent foundation definition. Many Florida manufactured home parks have mixed foundation status.
What is the Citizens HO-7 mold sublimit for Florida mobile homes?
Citizens HO-7 mobile home policies carry the same $10,000 MRSR mold remediation sublimit as HO-3 homeowner policies. This sublimit applies only to licensed mold remediation services (MRSR-licensed contractor performing mold treatment). Structural drying, flooring removal and replacement, drywall replacement, subfloor repair, and belly wrap restoration are Coverage A and are not subject to the $10,000 cap. The practical impact is that mold treatment in a manufactured home belly cavity — if mold develops before drying is complete — is capped at $10,000 while the surrounding structural scope is not.
