RESEARCH SOUTH PASADENA
Local History Research Resources
Use historic inventories, building records, maps, photographs, directories, newspapers, and local collections to investigate a property, landmark, street, person, or neighborhood.
Start With Four Core Sources
1. Historic Resource Inventory
Check whether a property or district has documented historic significance.
2. Building Records
Review permit history, construction dates, alterations, and available plans.
3. Historic Maps
Compare parcel patterns, building footprints, streets, and land use over time.
4. Local Collections
Use photographs, directories, newspapers, books, oral histories, and institutional records.
A Practical Property-Research Workflow
Begin with the present-day address, confirm parcel and construction information, compare historic maps, identify owners and occupants through directories or public records, then connect the property to photographs, newspapers, and neighborhood history.
Step 1
Confirm the current address and parcel identity.
Step 2
Establish an approximate construction date.
Step 3
Compare maps and building footprints over time.
Step 4
Connect people, photographs, and published history.
Cross-Check Every Source
Historic records can conflict. Dates may reflect permits rather than completion, addresses can change, names may be misspelled, and photographs may be misidentified. Strong research uses multiple independent sources before drawing a conclusion.
