Flooding is one of the most costly and unexpected natural disasters that homeowners face. While many people assume that their standard homeowners insurance protects their entire property from flood damage, the reality can be quite different. Flood insurance through the National Flood Insurance Program (NFIP) or private insurers often has specific rules regarding what structures are covered—including detached buildings like garages, sheds, and workshops.
If you own additional storage structures on your property, understanding their coverage status is essential. Knowing whether your garage or shed is included in your flood insurance policy can help you avoid significant financial loss in the event of a flood.
Understanding What Flood Insurance Covers
Flood insurance is designed to protect your property from damage caused by rising water from outside sources—not from internal plumbing leaks. Coverage is typically divided into two parts:
- Building Coverage
- Contents Coverage
However, coverage rules for detached structures like garages or sheds vary depending on the policy and insurer.
Are Garages Covered by Flood Insurance?
In most NFIP policies, one detached garage is automatically covered under building coverage—but only to a limit. This means:
- The garage must be located on the same property as the insured home.
- The garage must be used primarily for storage or parking vehicles—not as an office, rental unit, or living space.
If your detached garage is large or contains valuable machinery, tools, or appliances, the standard NFIP limits may not fully cover replacement costs. Private insurers may offer riders or supplemental coverage depending on the provider.
What’s Typically Covered in a Garage:
- Structural elements (walls, foundation, roof)
- Permanent fixtures (built-in cabinets, electrical systems)
- HVAC units installed in the structure
What’s Usually Not Covered:
- Furniture
- Personal belongings (unless contents coverage is purchased separately)
- Converted living spaces
- Luxury upgrades not listed in the policy
Are Sheds Covered by Flood Insurance?
Unlike detached garages, sheds are not automatically covered under standard NFIP flood insurance policies. Most sheds fall under the category of “other structures,” meaning they must be specifically listed and insured to receive coverage.
If your shed houses expensive lawn equipment, tools, boats, or recreational gear, leaving it uninsured could mean paying out-of-pocket to replace everything after a flood event.
Sheds May Need Separate Coverage If Used For:
- Gardening and lawn equipment
- Tools and power machinery
- Recreational storage (kayaks, bicycles, camping equipment)
- Hobby or workshop spaces
Private flood insurance policies often provide broader options for shed coverage, making them worth comparing if you need flexibility.
What Flood Insurance Does Not Cover in Either Structure
Regardless of whether the building itself is covered, most flood insurance policies exclude the following from garages or sheds:
- Cash, collectibles, and valuables
- Vehicles (covered under auto insurance with comprehensive coverage)
- Landscaping damage
- Decks and patios
Homeowners should review policy exclusions closely to avoid unexpected gaps.
Local Risk Awareness
If you live in a coastal or low-lying community, you may face greater risk of flooding. Flood-prone areas in Fort Pierce, FL, for example, experience storm surges, heavy rainfall, and seasonal weather patterns that make flood protection for detached structures particularly important.
Tips for Ensuring Your Detached Buildings Are Fully Protected
To avoid gaps in coverage, consider the following steps:
- Review Your Current Policy
— See whether garages or sheds are included and to what extent.
- Document Inventory
— Keep photos and receipts of equipment stored inside.
- Consider Additional Riders — Supplemental coverage may be needed, especially for high-value items.
- Maintain Proper Elevation and Floodproofing — Elevating equipment may help reduce loss and improve insurability.
Final Thoughts
Garages and sheds play an essential role in home function, storage, and convenience—but they’re not always fully protected under standard flood insurance policies. Understanding what is and isn’t covered allows you to make informed decisions about additional coverage, supplemental riders, or private insurance alternatives.
Whether you’re in Fort Pierce, FL, or elsewhere, reviewing your flood insurance annually and speaking with a knowledgeable insurance agent can help you avoid costly surprises and safeguard your entire property—inside and out.
