Stanislaus County Assessor David Cogdill Sr. will leave county office Oct. 18 to join the California Building Industry Association as president and chief executive officer.
Cogdill announced his intentions in a Thursday letter to Stanislaus County Board of Supervisors Chairman Vito Chiesa.
Cogdill is a former state Senator who took office as assessor in 2011.
"It will be a privilege to lead CBIA in these dynamic times," Cogdill said. "CBIA has forged its reputation in Sacramento based on trust, integrity and working collaboratively toward thoughtful policy solutions to some of our state's most pressing challenges. I am honored to build on this strong history and lead CBIA into the future."
Cogdill served in the Legislature from 2000 to 2010, serving for a time as head of the Senate Republican caucus.
The county assessor position comes up for election in June. Cogdill's term was to run through 2014.
The office is responsible for valuing the 175,000 taxable real estate parcels in Stanislaus County, which have a current value of $34 billion. The office has a 54 employees and a $5.5 million annual budget.
County leaders are expected to discuss appointing an interim assessor until voters put a new assessor in office.
"There are very capable folks in the assessor's office who can pick up the duties," Cogdill said today.
Cogdill said the CBIA has searched for a new CEO for about six months. He said a recruiter contacted him about leading the statewide organization.
"It's an exceptional opportunity that I'm looking forward to and don't think I could pass up," he said.
