265.45 Safe storage of rifles, shotguns, and firearms.
No  person who owns or is custodian of a rifle, shotgun or firearm who
  resides with an individual who such person knows or has reason  to  know
  is  prohibited  from possessing a firearm pursuant to 18 U.S.C.  922(g)
  (1), (4), (8) or (9) shall store or otherwise leave such rifle,  shotgun
  or  firearm  out  of  his or her immediate possession or control without
  having first securely locked  such  rifle,  shotgun  or  firearm  in  an
  appropriate  safe  storage  depository or rendered it incapable of being
  fired by use of a gun locking device appropriate  to  that  weapon.  For
  purposes  of this section "safe storage depository" shall mean a safe or
  other secure container which, when locked, is incapable of being  opened
  without the key, combination or other unlocking mechanism and is capable
  of  preventing  an  unauthorized  person  from  obtaining  access to and
  possession of the weapon contained therein. With respect to a person who
  is prohibited from possessing a firearm pursuant to 18 USC   922(g)(9),
  for  purposes  of this section, this section applies only if such person
  has been convicted of a crime included in  subdivision  one  of  section
  370.15  of  the  criminal procedure law and such gun is possessed within
  five years from the later of the date of  conviction  or  completion  of
  sentence.  Nothing  in this section shall be deemed to affect, impair or
  supersede any special or local act  relating  to  the  safe  storage  of
  rifles, shotguns or firearms which impose additional requirements on the
  owner or custodian of such weapons.
A violation of this section shall constitute a class A misdemeanor.
