First Amendment Threat?

This is really odd language to be included in an ordinance. Why is it there?

SECTION 11 OWNER LIABLE
In addition to any other person or persons involved in a violation or threatened violation of this Ordinance, the owner of record of any property falling under the jurisdiction of this Ordinance shall be responsible both criminally and civilly for any construction, alteration, excavation, or any other activity occurring on the property which is contrary to the provisions of this Ordinance.

First Amendment to the US Constitution

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
