Section 27-2014. Window frames and fire escapes

a. At least once every five
  years, the owner of a dwelling shall paint all  exterior  window  frames
  and  sashes  with  one  coat  of  an  exterior paint. The department may
  require a more frequent repainting of any window frame or  sash,  as  it
  deems  necessary.  This subdivision shall not apply to window frames and
  sashes of approved atmospheric corrosion resistant metal.
    b. The owner of a dwelling shall paint  every  fire  escape  with  two
  coats  of  paint  of contrasting colors. The owner shall paint the first
  coat before and the second after erection of a new fire  escape,  except
  that  this  shall  not  apply  to  fire  escapes constructed of approved
  atmospheric corrosion resistant metal. Whenever a  fire  escape  becomes
  corroded,  the  owner shall scrape and remove the corrosion products and
  repaint it with two coats of paint of contrasting colors.
