Mobile City

Mobile City is a small incorporated Rockwall County community near Interstate 30 on the outskirts of Rockwall. Its origin as a mobile-home community is described in the Handbook of Texas. Mobile City and the City of Rockwall are separate municipalities, so a nearby Rockwall location is not enough to identify the governing jurisdiction.

Check at the address, not the town name

• Confirm the actual city boundary before applying Rockwall permit or service information.
• Check the ownership of both the home and the underlying land, together with any lease or recorded restrictions that apply.
• School attendance zones, flood risk, HOA obligations, utilities and property taxes follow the exact address. Use current records: TEA school district locator, FEMA flood maps, county appraisal districts.
