Okay, here goes. In 86 we had a "100 year flood" in MI. In 93 I built a new house on my dad's old home place. Like many small twps of that time I went to township office and got bldg permit and built new house with full basement. I should also mention, I built new pole barn one year earlier. During construction in 93 I heard rumors that no new permits were to be issued and that a state DNR (dept natural resources) official challenged the supervisor and he told them it was "his township and he was in charge". What I didn't know was that I was in the "100 yr flood plain". Fast forward about five years. The neighbor around the corner adds on to his farmhouse and has to apply to DNR for permit. The official tells him, "you can add on with a crawl space but don't you dare put in a basement like so and so, (uses my name)! "If I wanted to I could make him fill in his basement. No one in this flood plain was supposed to get a permit". Like many small townships of the time we had few building ordinances in 93, heck we were lucky to get an inspection. Only a general inspec was required and I never even got an occupancy permit when finished (we didn't have an inpector at the time). Now its 2010 and I would like to add on a 3 season room, but I'm scared to ask for a permit. I'm afraid they'll tell me to fill in my basement. (They acually did make another man fill in his basement in the same flood plain, although he was warned during construction). I honestly did not know about the flood plain when building. What do you guys think?
