Questions to ask next: which edition and section the finding is written against, in writing; what exactly was observed and what the inspector expects at re-inspection; the correction deadline on the notice. Disagree with the reading of the code? Ask the inspector for the section and edition in writing, then the fire or building official for a written interpretation.
