Sewage backup is not
covered by default.

No. Standard Florida HO-3 policies universally exclude damage from water or sewage that backs up through drains, sewers, or sumps. This exclusion applies regardless of the cause of the backup — a municipal sewer overload, a clogged main line, or heavy rain flooding the sewer system. The exclusion is explicit in virtually every standard homeowners policy. Sewage backup coverage is only available as a separate endorsement (rider) added to the policy, typically called 'Water Backup and Sump Discharge or Overflow' coverage. Without this endorsement, a sewage backup event that destroys flooring, drywall, and contents is entirely out-of-pocket.

A standard water backup endorsement covers: sewage backup through floor drains, toilets, bathtubs, and sinks; sump pump overflow or discharge; and water backup from municipal systems entering through interior drains. It covers the resulting water damage to floors, walls, contents, and structure within the home. It does NOT cover: flood water entering through doors, windows, or foundation (requires NFIP flood insurance); storm surge; or damage to the sewer line itself outside the home (requires separate service line coverage). Coverage limits vary by carrier — commonly $5,000–$25,000 with higher limits available for additional premium.

The water backup endorsement is one of the most cost-effective insurance add-ons available. Florida homeowners typically pay $50–$200 per year for $10,000–$25,000 of coverage, depending on the carrier and coverage limit chosen. Carriers like State Farm, Allstate, and Citizens offer it as a standard add-on to homeowners policies. The average sewage backup cleanup and restoration job in a residential home costs $3,000–$20,000+ — making the annual endorsement premium a low-cost hedge. If you don't have this endorsement and have a finished basement, ground-floor living areas, or an older home with clay sewer lines, adding it should be a priority at your next renewal.

Citizens Property Insurance offers a Limited Water Damage endorsement that includes some sewer and water backup coverage, but the standard Citizens HO-3 policy itself excludes sewage backup. Policyholders who added the endorsement before their policy was renewed may have coverage; those who didn't will have no coverage for backup events. Citizens policies have been subject to significant changes in recent years — if you have Citizens insurance, call your agent specifically to confirm whether water/sewage backup is included in your current policy and at what limit.

First, call CFDR at 321-420-7274 immediately — sewage backup is a Category 3 biohazard and requires professional cleanup regardless of insurance coverage. Delaying cleanup to figure out insurance is a health risk and compounds the damage. Second, check your policy documents for any water backup language — it may have been included without your awareness, or your agent may have added it during a renewal. Third, if there's no coverage, remediation still must happen — ask about payment plans. Fourth, report the backup to your municipality if it appears to be caused by a municipal sewer overload — there may be liability on the city's part that your attorney can pursue. Finally, add the endorsement at your very next renewal.
