If the Building Commissioner finds that a sign or other advertising structure regulated by this chapter is unsafe or insecure, or is a menace to the public or violates a provision of this Zoning Code, he or she shall give written notice to the owner or permittee thereof. If such owner or permittee fails to correct the situation within ten days after receipt of such notice, the structure may be removed or altered by the Commissioner at the expense of such owner or permittee.
   Permits may be revoked at any time by order of the Commissioner when violations of this Zoning Code exist. The Commissioner may cause the removal of any sign which is an immediate peril to persons or property, and such removal shall be made without notice.  All existing signs shall comply with this chapter, and, when nonconforming, shall be altered to comply, except as provided in Section 1280.03.
   A sign which no longer advertises a bona fide business or product shall be removed by the owner, his or her designated agent or other person having use of the premises within ten days after written notification from the Commissioner. If the sign is not removed, the Commissioner may remove the sign at the expense of the owner.
   Whenever a sign obstructs a street or sidewalk, the Commissioner shall cause the same to be removed.
