No person shall demolish any building within the City without first obtaining a written permit for the same from the City. No person shall backfill or level any excavation remaining from any demolition without similarly having obtained a permit for the same. The issuance of a permit by the City shall not render the City responsible or liable for any damages which may ensue by the permittee’s demolition of a building, and said permittee will indemnify and defend the City should action be brought for the same. Any judgment or action rendered in a case involving damages for demolition of a building shall be the sole responsibility of the permittee.
