§ 9-12.802. Administration.¶

(a) Order: Service. The Building Official shall issue an order as provided in this section to the owner of each building within the scope of this chapter. Orders will be issued within 30 days of the effective date of the ordinance codified in this chapter and thereafter as necessary.

(b) Order: Contents. The order shall be in writing and shall be served personally or by certified or registered mail upon the owner as shown on the last equalized assessment roll and upon the person, if any, in apparent charge or control of the building. The order shall specify that the building has been determined by the Building Official to be within the scope of this chapter and, therefore, is required to meet the minimum seismic standards of this chapter. The order shall be accompanied by a copy of Section 9-12.801 of this chapter which sets forth the owner's alternatives and time limits for compliance.

(c) Order: Appeal from. The owner of the building or other aggrieved person may appeal the Building Official's initial determination that the building is within the scope of this chapter to the Board of Appeals. Such appeal shall be filed with the Board of Appeals within 60 days from the service date of the order described in this section. Any such appeal shall be decided by the Board of Appeals no later than 90 days after written notice of such appeal has been filed with the City Clerk and the grounds therefor shall be stated clearly and concisely. Except as otherwise provided herein, or as provided in Sections 105 and 106 of the Uniform Building Code, appeals or requests for modifications from any other determination, order or action by the Building Official pursuant to this chapter shall be controlled by the provisions of Chapter 4 of Title 1 of this Code.

(d) Recordation. At the time that the Building Official serves the aforementioned order, the Building Official shall also record in the office of the County Recorder of Ventura County a certificate stating that the subject building is within the scope of this chapter and is a potentially earthquake hazardous building. The certificate shall also state that the owner thereof has been ordered to structurally analyze the building and to structurally alter or demolish it where compliance with this chapter has not been demonstrated.

If the building is either demolished, found not to be within the scope of this chapter or is structurally capable of resisting minimum seismic forces required by this chapter as a result of structural alterations or an analysis, the Building Official shall record in the office of the County Recorder of Ventura County a form terminating the status of the subject building as being classified within the scope of this chapter.

(e) Order: Enforcement. If the owner in charge or control of the subject building fails to comply with any order issued by the Building Official pursuant to this chapter within any of the time limits set forth in Section 9-12.801 of this chapter, the Building Official shall verify that the record owner of the building has been properly served. If the order has been served on the record owner, the Building Official shall order that the entire building be vacated and that the building remain vacated until compliance with such order. If compliance with such order has not been accomplished within 90 days after the date the building has been ordered vacated or such additional time as may have been granted by the Board of Appeals, the Building Official may order its demolition in accordance with the provisions of Section 203 of the Uniform Building Code.
