Ground Mount Fencing Required
Yes
Ground Mount Notes

Ground Mounts: With regard to fencing….we require that any conductors that may be incidentally contacted are protected from damage or tampering by unauthorized persons. This can be accomplished with fencing or approved metal conduit where no conductors are unprotected within reach proximity. **I spoke with Eddie - he confirmed that there is no way you can cover all of the wires with just conduit. Fencing is required.**

Compiled from public records, 2026. Requirements change with code cycles and local amendments. Verify with the City of Vista (CA) building department before you rely on this, and treat it as a research head start, not a ruling. Getting quotes? Run them through the quote checker first.
