What's covered
Burst pipes and appliance failures
A pipe that lets go or a washing machine that floods the unit is sudden internal water damage — your damaged belongings are covered.
Rain through storm damage
Rain entering through a wind-damaged roof or window is part of a covered wind loss, not a flood.
Overflow from upstairs
A neighbor's tub or supply line failing above you is covered internal water damage from your policy's perspective.
What's not covered
Rising water, from any cause
Flash floods, river flooding, storm surge, mudflow — if water rose from outside, the loss is excluded, no matter how sudden or severe.
Sewer and drain backup, usually
Water backing up through drains is typically excluded unless you added a backup endorsement — a cheap add-on worth asking about in ground-floor and basement units.
The mold that follows
Because the flood is excluded, the mold it causes is too.
Renters live in flood zones more than they think
Flood maps aren't a homeowner concern that skips renters — apartment buildings sit in mapped high-risk zones too. Florida, from our own dataset:
21%
of Florida apartment communities we track sit in a FEMA high-risk flood zone (zones A and V)

How renters close the flood gap
Flood coverage for renters is contents-only — you insure what you own, not the building — which makes it one of the cheaper policies in insurance, particularly outside high-risk zones. It's sold through the National Flood Insurance Program and a growing number of private flood insurers, and NFIP policies typically carry a 30-day waiting period, so the week a storm is named is too late to buy.
Check your building's zone on FEMA's free flood map service. Zones starting with A or V are high-risk — there, contents flood coverage should be treated as part of the real cost of the apartment. Zone X is lower risk, and coverage is correspondingly inexpensive. Ground-floor and garden-level units carry most of the practical risk regardless of zone: elevation within the building is the variable flood maps don't see.
One more gap worth closing while you're at it: ask your carrier about sewer-backup endorsement. It's a different exclusion than flood, it's cheap, and for basement-level renters it's the more likely claim.
Common questions
What's the difference between water damage and flood damage?
Source. Water that originates inside the plumbing system — burst pipes, appliance failures, an upstairs overflow — is covered water damage. Water that rises from outside — storms, rivers, surge, runoff — is flood, and it's excluded from renters policies entirely.
How do renters buy flood insurance?
As a contents-only flood policy, through the NFIP (via any participating insurance agent) or a private flood insurer. Because there's no building to cover, renters flood policies are among the cheapest sold — but NFIP coverage generally has a 30-day waiting period, so buy ahead of the season, not the forecast.
Does FEMA assistance replace flood insurance for renters?
No. FEMA disaster grants for renters are limited, capped, and only available after a federal disaster declaration — they're a safety net, not a replacement policy. Renters with real property value in a flood-prone unit shouldn't plan around them.
Is my basement apartment covered differently?
The exclusions are the same, but the exposure isn't — below-grade units flood first and worst. If you rent one, the two most valuable add-ons are a contents flood policy and a sewer-backup endorsement, in that order.
