How this record is built.

This record is compiled by the Arroyo Casa Archive of Records from public documents: city and county historic resources surveys and inventories, National Register nominations, landmark designation reports and council records, planning documents and preservation groups' publications, plus the building notices of 1917 to 1930, printed as houses were permitted, contracted or announced. Where a house was matched to the Los Angeles County Assessor's record at the same address in the same city, the page says whether the county confirms it standing. A house is shown only when one of those documents names its architect, and the builder and the first family are shown beside the architect where a document names them. Each house carries the kind of document behind it, and a credit the document itself calls likely, probable, possible or attributed is marked attributed. The methodology and every source document are on one page.
