TxDMV issues a single-trip permit for the transportation of portable buildings and portable building compatible cargo when exceeding Texas legal size limits. Single-trip permits may only be used for one movement, during the times specified on the permit, from a specific point of origin to a specific destination.
To qualify for the portable building single-trip permit, the vehicle and load must be no greater than 14 feet high and 80 feet long. Vehicles and/or loads exceeding these dimensions require a general single-trip permit.
NOTE: You must verify the size and weight limits needed BEFORE seeking a special permit.
Operating Authority Requirements
During the permit application process, you must provide your USDOT Number. TxDMV will check the number against the Federal Motor Carrier Safety Administration (FMCSA) system, MCMIS, for any out-of-service orders prior to permit issuance. The permit will be issued to the company name as it is listed for the USDOT Number.
