Where can I find historical photos of my home?

There are 3 resources for Seattle area homeowners to search photographic records of their home.

1. Washington State Archives (Puget Sound Branch) & King County Archives 
The Online image search only available for homes from 1937-1972.
The King County Assessor’s Real Property Record Cards capture information through time necessary to value land and buildings for the assessment and collection of property taxes. The cards were created as part of a survey funded by a contract between King County Assessor and the federal Works Progress Administration (WPA). The survey began in 1937 and was completed in 1940. The Real Property Record Cards were updated by the Assessor’s Office through 1972. The cards contain information on individual parcels of property, including legal descriptions, building types, building uses, number of rooms, construction details, and at least one photograph of each building on the parcel. If significant exterior changes were made to the buildings additional photographs were taken.

Puget Sound Regional Archives (PSRA) in Bellevue holds the original Real Property Record Cards. Contact them with the property's tax parcel number to order copies of the house photos and the information on the cards

For homes built before 1937:

2. Seattle Microfilm Library
Contact the Microfilm Library via email sci_microfilm@seattle.gov to ask for any images they may have in the archive. You will need to know your homes parcel number (you can find this in the third resource).
