/diy/ - Do It Yourself

I bought a custom built home from the original owner. I want to make some structural modifications to the house. I am a licensed structural engineer, so this will not be an issue.

I would like determine the size and spacing of my roof joists (without cutting holes in the sheetrock). The owner was not able to provide me with any building plans for the house (he died). Is there typically a permitting department at the city or county level that would have a set of plans?

The home was built only a few years ago, so I am hoping that there is some record of the building permits or at least who the architect was. The problem is that there is no "building department" nor a "permitting department" in my county. Is there some other name that this department goes by?
