The document outlines the five stages of the life cycle for affordable housing units to count on the Subsidized Housing Inventory (SHI): 1) Permitting units, 2) Creating units, 3) Occupying units, 4) Counting units, and 5) Monitoring units. It describes the key actions needed at each stage, including establishing an regulatory framework, finalizing plans, inspecting and monitoring construction, marketing and leasing units, updating inventories, and ongoing compliance monitoring. The entire process aims to get affordable housing units counted initially and kept on the SHI over time.
