Department of Conservation and Development

Due to the Order issued by the County Health Officer on March 16, 2020 (and the subsequent Order issued on March 31, 2020), all offices of the Department of Conservation and Development are closed to the public until further notice. 

We continue to process certain applications and permits, and to perform construction inspections for certain projects, but only as consistent with the requirements of Health Officer’s Order. We are striving to continue to operate our other programs and services to the extent possible by working remotely and while supporting the County’s emergency response efforts, but please be patient with us given the extreme limitations this presents.

Please call (925) 674-7200 with questions, to schedule an inspection for an active building permit, or to discuss procedures for submitting new applications.

The Department of Conservation and Development also works on projects and programs that save energy, create healthy and safe communities,  increase affordable housing, and create jobs.
