The Housing series measures 1.2 cubic feet and dates from 1975 to 1990. The subjects most well-documented are the Housing Maintenance/Preservation Ordinance and the Senior Housing Program, although there is also information relating to accessory apartments. Downtown housing issues overlap with the Downtown Plan and researchers should consult both series.

First passed in 1980 and amended in 1981, the Housing Preservation Ordinance prohibited demolition of sound residential structures for putting in a vacant lot or parking lot. The ordinance required approved replacement use before a demolition permit was issued. It also required funding housing replacement or providing a share of the financial equivalent. In 1984 the fee required for the demolition of residential structures was found to be unconstitutional by the State; a replacement ordinance was introduced and passed in 1985. The 1985 ordinance incorporated the licensing of demolition and change of use of residential structures, and provided eviction protection and relocation assistance for displaced tenants. The State again found the ordinance unconstitutional in 1987 because of its tax on development in the replacement provisions (San Telmo Associates v. Seattle, 108 Wn. 2d 20). The records provide insight into the process of crafting the ordinance as well as background on low-income housing in downtown Seattle.

The Senior Housing Program records date from 1980 to 1986 and primarily address issues relating to bonds for elderly and disabled housing. Discussions through correspondence include putting the bond issue on the ballot in 1981, the work program for the bond issue, and housing issues related to low-income elderly and disabled people. Public hearing rosters and Council decision agendas are included. These records also include discussion of how to allocate the $5 million of unallocated funds in 1986.
