Summary
Manteca retaining walls need an approved grading permit or roadway project, not a standalone fence permit, and walls over 4 feet must be benched so no single tier exceeds 6 feet.
There shall be no height limits for retaining walls when constructed along the exterior property lines of the project or the final interior property lines in the case of a residential subdivision. Otherwise, a retaining wall over 4 feet in height shall be benched so that no individual wall exceeds a height of 6 feet, with the depth of each bench a minimum of 3 feet.

Full Breakdown
Manteca Municipal Code § 17.46.030(B) treats retaining walls separately from ordinary fences: they may only be built as part of an approved grading permit or as part of a roadway improvement project, with no standalone fence permit option. Under § 17.46.050(C), retaining walls built along a project's exterior property lines, or the final interior property lines of a residential subdivision, carry no height limit at all. Elsewhere on a lot, a retaining wall taller than 4 feet must be benched so that no individual wall section exceeds 6 feet, with each bench at least 3 feet deep.
Violations & Fines
Building a retaining wall over 4 feet without benching each tier to 6 feet or less, or constructing one without an approved grading permit, violates § 17.46.050 and § 17.46.030.
