Duncanville, Texas
Duncanville is a suburban city in southwestern Dallas County, part of a cluster of communities known locally as the Best Southwest, along with neighboring Cedar Hill, DeSoto, and Lancaster. It lies roughly 11 miles southwest of downtown Dallas on the rolling prairie south of the Trinity River, developed largely as a residential community within the Dallas metropolitan area.
Property here runs through the Dallas 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 Dallas County notes below cover the practical details, with the official county directory for the appraisal district and tax office.
