Yes, a "spring house" (a building used to house a spring's water source) is eligible for flood insurance under the National Flood Insurance Program (NFIP) if it's a walled and roofed building, on a permanent foundation, and located in a participating community.
NFIP Coverage:
The NFIP insures most walled and roofed buildings that are principally above ground on a permanent foundation, including mobile homes, and buildings in the course of construction.
Spring House Definition:
A spring house, as a building, falls under this general category, even if it's used specifically for housing a spring's water source.
Eligibility:
If the spring house meets the above criteria and is located in a community participating in the NFIP, it is eligible for flood insurance.
Flood Insurance is Separate:
It's important to note that standard homeowner's insurance policies typically do not cover flood damage, so a separate flood insurance policy is needed.
Mortgage Requirements:
If you have a mortgage from a government-backed lender and live in a high-risk flood area, you may be required to have flood insurance.
Flood Zones:
High-risk flood areas begin with the letters A or V on FEMA flood maps and are also known as special flood hazard areas (SFHAs).
Low and Moderate Risk:
FEMA's low and moderate-risk flood zones – those outside the SFHA – are those that begin with the letters “X,” “B,” or “C.” Flood insurance is not required within these zones.
