Moving a manufactured home on Texas roads usually needs an oversize/overweight permit through the Texas Department of Motor Vehicles (TxDMV). The transporter normally gets this. Local rules can apply too: city or county placement permits, flood-zone rules, and sometimes septic or utility permits at the new site.
Ownership paperwork matters as well. TDHCA handles manufactured home ownership records (Statements of Ownership), and moving a home may need a record update. Rules change, so confirm current requirements with TxDMV, TDHCA, and your city or county before you move.
