  dangerous to human life and safety or detrimental to health, it may
    (1) correct such conditions, or
    (2) order the owner of the dwelling  or  other  responsible  party  to
  correct such conditions.
    b.  Where the department determines that any violation of this chapter
  or other applicable law exists in any dwelling or part of its  premises,
  it  may  order  the  owner of the dwelling or other responsible party to
  correct such conditions.
    c. An order issued pursuant to the preceding subdivisions shall  state
  the violations involved and the corrective action to be taken, and shall
  fix  a time for compliance, which shall be not less than twenty-one days
  from the date of service of the order, except  that  where  a  condition
  dangerous to human life and safety or detrimental to health exists or is
  threatened, a shorter period for compliance may be fixed.
