These time limits shall begin to run from the date the notice is served in accordance with section 9-5-203 of this article.
The owner shall submit an analysis or plans for demolition or wall anchors that fall within one of the following categories:
a. Within two hundred seventy (270) days after service of the notice, the owner of a building within the scope of this chapter shall submit a structural analysis which shall demonstrate that the building meets the minimum requirements of this chapter or is exempt from this chapter; or

The director shall determine that an analysis is adequate if the director determines that the analysis meets the purposes and requirements of this chapter. The city may hire independent consultants to assist with the review of these analyses. If the director of building and safety determines that the submitted report is inadequate, the specified inadequacies shall be immediately corrected by the property owner's engineer or architect to the satisfaction of the director of building and safety.
