The intent of this Title is to protect the availability of publicly assisted affordable housing for low and moderate income households by: providing for notice to the City and tenants when transitions from current assistance programs and/or affordable housing uses are planned; providing purchase opportunities for the City to attempt to preserve the affordable housing while respecting ownership interests of building owners; providing tenant relocation assistance when the affordable housing is converted; and, ensuring long term affordability in future projects that the City assists with public financing designed to create or preserve affordable housing.
