Homeless U.S. Citizens Have a Right to Vote

Voters must provide a residence address on the voter registration form, but this address may be any definable location in the county that describes their physical location. This could be a shelter, park, motor home, or other identifiable location. The mailing address of a person who is homeless or who resides where mail service is unavailable can be the office of the county clerk. Voters can pick up their ballot at the county elections office.​
