This was offered as a thank you, and to help with some stagnate water that does buildup in my yard.I'm concerned about liability.

If so, I would say you have bigger concerns than where to park your savings, and would instead focus on banking as much money as possible. 

If that's still not a concern then go for it. 

There aren't many of these in the market today, which means bond buyers shouldn't have the same cause for concern.

I have looked into getting non-conforming use permits, conditional use permits, zoning use variance requests, etc. but this process could still be very lengthy and I'm afraid this will open a can of worms that will cause the county to further look into it and raise more issues.My main concern/worry is that when it comes time to refinance the property after the (minor) rehab has been done, lenders may not finance the property on a long-term loan due to a non-conforming use of the property.

We saw it as a “we are all in this together” moment and maybe “its not all about the money” moment but are also concerned about setting a precedence.

The two biggest concerns that come out of this are:1 - Does your city/state require them to?
