(1) The department must report on its website on an annual basis, for each funding cycle:

(a) The number of homeownership and multifamily rental projects funded;

(b) The percentage of funding allocated to homeownership and multifamily rental projects; and

(c) For both homeownership and multifamily rental projects, the total number of households being served at up to 80 percent of the area median income, up to 50 percent of the area median income, and up to 30 percent of the area median income.

(2) All housing trust fund loan or grant recipients, except for those receiving preservation awards under RCW 43.185A.180, must provide certified final development cost reports to the department in a form acceptable to the department. The department must use the certified final development cost reports data as part of its cost containment policy and to report to the legislature. Beginning December 1, 2023, and continuing every odd-numbered year, the department must provide the appropriate committees of the legislature with a report of its final cost data for each project funded through the housing trust fund. Such cost data must, at a minimum, include:

(a) Total development cost per unit for each project completed within the past two complete fiscal years; and

(b) Descriptive statistics such as average and median per unit costs, regional cost variation, and other costs that the department deems necessary to improve cost controls and enhance understanding of development costs.

(3) The department must coordinate with the housing finance commission to identify relevant development costs data and ensure that the measures are consistent across relevant agencies.
