6. July 12, 1973

   The building, built as a six-storey warehouse of about 50,000 square feet per floor and long occupied by F. W. Woolworth and Company, belonged to the Far West Laboratory for Educational Research and Development, which had remodelled three floors; portable buildings of Opportunity Junior High School stood on half its parking lot. The City Planning Commission unanimously reported that the San Francisco Unified School District's acquisition of the second, third and fourth floors of the building as condominiums did not affect the Master Plan, provided the District sought more parking or playground space.
