Access Panel to gas stove shutoff valve on other side of wall in laundry room to code?
Yes, putting the gas service shut-off in the laundry room would be fine (though they are typically found behind the appliance).  Remember, this is a service disconnect valve (for maintenance or replacement of the appliance) not an emergency disconnect valve (in the event of a gas leak).  The "emergency disconnect valve"  is at the meter since the first rule for gas leak safety is to exit the building.
