It is the policy of the city of Petaluma to eliminate discrimination based on the fact that a person has AIDS or a related condition, or HIV infection. In adopting this ordinance, the city council of the city of Petaluma does not intent to proscribe any activity the proscription of which would constitute an infringement of the Constitution of the United States or the Constitution of the State of California. Recognizing that existing federal and state enactments proscribe such discrimination in some, but not all, circumstances, the city council finds that such enactments do not occupy the field of such arbitrary discrimination, but that local regulation is both necessary and proper. This chapter is not intended, and shall not be construed to apply to any person or activity which is regulated by federal or state law, to the extent that application of this chapter would conflict with such law or would unduly interfere with the achievement of federal or state regulatory objectives. It is the intention of the council of the city of Petaluma that this chapter shall be interpreted to be compatible with federal and state enactments, and in furtherance of the public policies which those enactments express. (Ord. 1903-A NCS §1 (part), 1992.)
