Demolition permits may be obtained from the office of the Clerk. Permits shall be issued at a cost as specified in the Appendix to this Code of Ordinances, but no permit shall be issued until the applicant therefor has given written assurances with respect to the disconnection and removal of existing sewer and water service lines serving the property demolished. The party requesting the permit must also supply the City with a schedule of demolition, and the demolition must be completed within such time schedule, but no later than two (2) weeks or fourteen (14) days after initial action to demolish the building has begun. An extension can be issued with this permit for special circumstances (such as dismantling) before excavation. Completion of the demolition of the building shall include the building and any basements, cisterns or other open areas.
