In short
- The standard flood policy covers a detached garage at the described location.
- The coverage is limited to no more than 10 percent of the limit on the dwelling.
- It does not cover a detached garage used for residential, business, or farming purposes.
What this means
This answer is about the federal National Flood Insurance Program (NFIP) standard policy. Under building coverage, the policy lists a detached garage at the described location. It says coverage is limited to no more than 10 percent of the limit of liability on the dwelling, that using this coverage reduces the building limit, and that it does not cover a detached garage used or held for use for residential, business, or farming purposes. The sources do not say how the 10 percent is counted for your policy; your declarations page shows your building limit.
Your next step
Check the building limit on your declarations page and how the garage is used. Report the loss to your insurer; see our answer about the proof-of-loss deadline for the proof-of-loss time.
Check it yourself
Open the policy text at the eCFR link and read Article III, paragraph A, item 3.
