The 2005 Legislature passed legislation moving the Vertical Housing Program from Oregon Economic and Community Development Department (OECDD) to Oregon Housing and Community Services (OHCS) beginning in November 2005. The program encourages mixed-use commercial / residential developments in areas designated by communities through a partial property tax exemption. The exemption varies in accordance with the number of residential floors on a project with a maximum property tax exemption of 80 percent over 10 years. An additional property tax exemption on the land may be given if some or all of the residential housing is for low-income persons (80 percent of area median income or below).
