To qualify for a residential homestead exemption, you must provide HCAD with a copy of your valid Texas driver's license or ID card showing the physical address of the residence for which you are applying. If you move within Texas, you have 30 days to update your address online or in person. For a new license, you must apply in person, provide identification documents, and pass a vision and driving test if required. Texas DPS has several locations in Harris County where you can apply for or update a driver's license.
