due not later than 30 days after the close of each period. Each report shall include, but not be limited to:
(i) an inventory of all buildings that are used or have been used to house inmates since January 1, 2018;
(ii) a catalog of changes in use or purpose for all housing units and buildings during the preceding period;
(iii) all housing units in each building and the original design capacity of each; (iv) all cells or rooms in each
housing unit and the number of beds in each cell or room; (v) a brief description of the housing unit
including, but not limited to, the custody level and function of the unit; (vi) the average daily amount of

has ever been occupied by inmates, with a brief description of each building and a statement as to
whether the building is used for housing; provided, however, that if the building is used for housing, the
report shall include whether it is occupied, unoccupied but available for future habitation or no longer
considered habitable; and (ix) the last date on which an inmate was housed in a housing unit or building
that does not currently house inmates; provided, however, that if multiple housing units in the same

may be aggregated for the purpose of inmate count reporting under clause (vii) and the number of
housing units aggregated shall be reported; and provided further, that for reporting under other clauses
above in which buildings or housing units are referred to individually, their official names need not be
used.
(b) The report shall be submitted to the Executive Office for Administration and Finance, the Senate and
