Summary
Turlock's grading code requires a retaining wall built to City standards whenever adjoining lots differ in elevation by more than one-half foot.
Whenever there is a greater than one-half (1/2') foot or greater difference in elevation between existing or proposed lots, a retaining wall shall be constructed to City standards.
(b) Setbacks.
(1) The tops and toes of cut and fill slopes shall be set back from property lines and structures as far as necessary to provide for safety of adjacent property, safety of pedestrians and vehicular traffic, required slope rounding, adequate foundation support, required swales, berms and drainage facilities and applicable zoning requirements.
(2) The setbacks and other restrictions specified by this section are minimum and may be increased by the chief building official or by the recommendations of a civil engineer, soils engineer or engineering geologist, if necessary, for safety and stability or to prevent damage of adjacent properties from deposition or erosion or to provide access for slope maintenance and drainage. Retaining walls may be used to reduce the required setbacks when approved by the chief building official.
(c) Preparation of ground. The ground surface shall be prepared to receive fill by removing vegetation, noncomplying fill, topsoil and other unsuitable materials scarifying to provide a bond with the new fill.
(d) Cut and fill slopes.
(1) Cut and fill slopes shall be in general, no steeper than is safe for the intended use or is necessary to insure the protection and safety of adjacent properties.

Full Breakdown
Under Turlock Municipal Code Section 7-4-106(a)(8), part of the City's grading regulations, a retaining wall must be constructed to City standards whenever there is a greater than one-half foot difference in elevation between existing or proposed lots. This obligation arises within the grading-permit process under Section 7-4-103. Retaining walls tied to a building, or exceeding the height that triggers a building permit, are also subject to the state-adopted California Building Standards Code applied through Title 8 of the city code -- Turlock's own text sets the grading trigger but not a maximum wall height.
Violations & Fines
Grading that creates the required elevation difference without building the mandated retaining wall violates Section 7-4-106(a)(8) and can hold up grading or building permit approval.
