The Board of County Commissioners legislates and administers County government within the limits of its authority granted in the Lane County Home Rule Charter. The charter grants legislative and administrative power to the full-time, paid five-person board.

Individually, board members may seek to address the needs of constituents and carry out special assignments as the full Board may direct. This program includes Performance Auditing, which provides the board with independent management audits of selected programs within Lane County government.
