I recently put an addition on my house with an attached screened porch. The house and the porch share a common attic space. The ceiling on the porch is tounge and groove redwood. I had the final inspection and the inspector said I needed to take down the wood and put up drywall due to the common attic space.
First of all I would like to know if this is correct, the inspector could not tell me where in the code book to look. Secondly if it is correct, is there another alternative? Any input is greatly appreciated.
