Summary
Stanislaus County treats retaining walls as regulated grading structures under its local amendments to the California Building Code's grading appendix. Anyone building a retaining wall in the unincorporated county pays a separate plan-review fee and a separate grading-permit fee, on top of whatever fee applies to the rest of the grading job, before the building official signs off.
Section J112.2 Plan Review Fees, is added to read as follows: When a plan or other data are required to be submitted, a plan review fee shall be paid at the time of submitting plans and specifications for review. Said plan review fee shall be as set forth in Table J-1 or as set forth in the fee schedule adopted by the board of supervisors. Separate plan review fees shall apply to retaining walls or major drainage structures as required elsewhere. ... Section J112.3 Grading Permit Fees, is added to read as follows: A fee for each grading permit shall be paid to the building official as set forth in the fee schedule adopted by the Board of Supervisors. Separate permits and fees shall apply to retaining walls or major drainage structures as required.
Full Breakdown
05 rewrite Appendix J of the California Building Code, the state's grading standard, to add local fee provisions. ' In practice, a homeowner or contractor building a retaining wall in the unincorporated area cannot fold the wall into a single grading fee for the rest of a site; the county's fee schedule, set by the Board of Supervisors, carries its own line item for the wall, reviewed and permitted independently of the surrounding excavation or fill. The ordinance does not set a blanket height threshold in this section, instead it routes engineering review through the standard California Building Code Appendix J grading-permit process, which requires plans and calculations for walls that retain fill or cut slopes.
Because the fee is separate, a project that adds a retaining wall after the original grading permit was issued still triggers its own review and fee before work can proceed.
Violations & Fines
Building or altering a retaining wall in the unincorporated county without the separate grading permit and plan-review fee required by Section 16.05.060 is a building-code violation the county building official can enforce through stop-work orders and permit denial until the fee is paid and plans are approved. Unpermitted walls discovered during a later grading or building inspection can delay or block approval of the surrounding project.
