San Diego, Texas
San Diego is the seat of Duval County, in the South Texas brush country west of Corpus Christi and northeast of Laredo. The town sits amid the ranching lands and mesquite country of the region, an area with deep roots in Spanish and Mexican land grants that predate the county itself. It served as an early trade and county center as the surrounding country was settled through the nineteenth century.
Property here runs through the Duval Central Appraisal District and the county tax office — the homestead exemption, the appraisal cap, protests, and any MUD, PID, or special districts all sit at the parcel level. The Duval County notes below cover the practical details, with the official county directory for the appraisal district and tax office.
