Interestingly, I talked to the girlfriend on this and there is a section of the OAC that describes exactly what you are saying....
5101:2-7-12 Site and safety requirements for a foster home.
(F) A foster home shall comply with the following requirements regarding weapons:
.....(1) The following weapons kept on the grounds of or in a foster home shall be stored in an inoperative condition in a locked area inaccessible to children:
..........(a) Firearms.
..........(b) Air rifles.
..........(c) Hunting slingshots.
..........(d) Any other projectile weapon.
.....(2) All ammunition, arrows or projectiles for such weapons shall be stored in a separate locked space.
.....(3) Any foster caregiver who is also a law enforcement official and can document that their jurisdiction requires them to have ready and immediate access to their weapon shall be exempt from the requirements of this paragraph.
She says how stringent each of those are is up to the inspector. She says one state inspector that sometimes does the inspection to insure the county inspectors are doing it right is very anal when it comes to firearms. She says he once removed a home temporarily from the list due to a model firearm that was hanging on the wall. The item didn't even fire, but since it wasn't stored away, it violated the above.
