Mono County Community Development — Planning

Official county Planning map/information function. County zoning applies to its unincorporated jurisdiction; included city maps, federal/state land and third-party reference layers do not transfer planning authority. Map access, inquiry and partial community-map limits remain stated on each service.

Mono combined General Plan and zoning map information (opens in a new tab)Official instructions

Community Development explains that the county combines its General Plan and Zoning Code and links General Plan Maps and the Parcel Viewer. The stated policies govern the unincorporated county; Town of Mammoth Lakes data does not become county zoning jurisdiction.

Explicit combined-plan context; not a generic assumption that all General Plan maps are zoning maps

Mono County is unique in that the General Plan and Zoning Code have been combined into one document.
