As I read the reg and the preamble in the federal register, only structures that are for residential use are allowed to be exempt. Therefore, the 3 unused structures would have to have flood insurance. Does anyone else have a different take on this?
As Randy pointed out, the "Detached Structure" exemption applies to any building used for personal, family or household purposes. Here's how we explain it in our Flood Insurance training manual:
A bank does not have to require flood insurance for qualifying detached structures that do not serve as a residence. However, lenders should account for any safety and soundness considerations.
1. Qualifications:
Each of following must be met:
a. Multiple Buildings: There must be more than one building on the property.
b. Residence Structure: One building must serve as a residence (sleeping, bathroom or kitchen facilities).
c. Structure Purpose: The detached structure(s) must be used primarily for personal, family, or household purposes. However, it cannot serve as a residence (sleeping, bathroom or kitchen facilities).
2. Loan Purpose vs. Structure Purpose:
a. Loan purpose DOES NOT matter.
b. Structure purpose DOES matter.

Since you have multiple buildings and at least one serves as a residence, you need to look at the use of the other buildings. If they aren't being used for commercial/ag purposes, I think you can easily say they are for personal use. Maybe they are used to store their "stuff" or are simply vacant.
