The naked man

I go down the steps to the adjacent park with my dog..and I see the naked man, the neighbor who happens to live in the first floor suite of the apartment lobby, often and usually built for practicing dentists and podiatrists.
So unusual to see him living there. He is as always topless in his apartment, while my family and I freeze in 27th floor. Everyday he passes the halls of medical offices and the adjacent tin boxes filled with surgical supplies. Isn't this a violation?
