Thanks for reporting on SeeClickFix! If the issues presented here are occurring on City street, they would be under the jurisdiction of the Vallejo Police Department (VPD). The Code Enforcement Division addresses issues on maintenance of exteriors of private properties and inoperative vehicles on private properties.

However, if the issues presented here are occurring on private property (for example, multiple business commercial vehicles surrounding a private property) please contact the Planning Department as it may be a zoning issue. You may contact them at (707) 648-4326. Please use SeeClickFix again to report all of your non-emergency maintenance issues!
