Published local code-enforcement instructions; procedures and property jurisdiction remain agency-specific

The Code Enforcement Program enforces the building and zoning ordinances for the unincorporated areas of Contra Costa County. The code enforcement process is typically initiated by responding to citizen complaints and by staff proactively investigating violations. Our goal is to resolve conflict(s) through voluntary compliance. In the absence of voluntary compliance, the offices have a range of other options to encourage compliance including citations, administrative actions, and abatement.
