Tuolumne County requires encroachment permits for any construction or modification within the county road right-of-way. This includes driveway approaches, utility trenching, drainage improvements, mailbox installation, and any grading or paving that affects county roads. The Engineering and Development Division processes encroachment permit applications and inspects work for compliance with county road standards. Permits ensure that work does not compromise road drainage, structural integrity, or safety. Caltrans issues separate encroachment permits for work within state highway rights-of-way (SR 108, SR 120, SR 49). Contact Engineering at 209-533-5633 for applications.
Work without encroachment permit: stop work order, potential restoration at owner's expense.
