In the event conditions of compliance are not completed by the time period specified herein, and no extension for completion is requested by the applicant and granted by the city council, the city shall enforce bonds posted pursuant to any and all legal and equitable remedies.

In the case where a bond has been posted to ensure compliance with the pre-building inspection requirements, the bond may be used to secure, demolish, or remove such structure.
