Property research guide
San Diego development-record research
First confirm whether the property is within the City of San Diego or another jurisdiction in the county. Then identify the record type and approximate date of the work; both affect the appropriate research route.

01
Start with the City’s records guide
San Diego Development Services maintains building permits, plans, maps, and related development records. Its records guide identifies public online search tools and procedures for documents that require a records review or request.
02
Check the correct system and period
OpenDSD and the City’s online services do not have identical coverage. The City’s published guidance distinguishes certain permit categories that moved to Accela. Review the current guide rather than assuming one search covers every permit and every year.
03
Account for archival gaps
The City directs researchers of pre-1955 building records to the County Assessor and provides records-review procedures for later archived building plans. Not all historical property records are available. A records appointment or public-records request may be necessary when online information is incomplete.
