Pending removal to a hospital, a person taken into custody or ordered to be hospitalized pursuant to this chapter may be detained for not more than forty-eight hours in a licensed rest or nursing home, a licensed or unlicensed hospital, a community mental health services provider, or a county home, but the person shall not be detained in a nonmedical facility used for detention of persons charged with or convicted of penal offenses unless the court finds that a less restrictive alternative cannot be made available.
