Answer: 1  You will require the same documents used to obtain a regular building permit but you will also need to include a Fire Report if the damage was caused by a fire. The Fire Report details the extent and nature of the damage. 2  Other types of damage can include flood, earthquake, broken pipes or vandalism.
1 Mucosa -- innermost layer (closest to the lumen), the soft, squishy lining of the tract, consisting of epithelium, lamina propria, and muscularis mucosae.  Submucosa -- connective tissue supporting (outside, deep to) the mucosa.
The submucosa is the next layer toward the outside and contains the submucosal glands. These large purple-staining glands produce mucus which lubricates the esophagus. A layer of loose connective tissue is found external to the glands (orangish in color). This is still submucosa. Below the glandular layer you can see the muscularis mucosa and below this the submucosa. The easiest place to observe these two layers is in the folds.
