Summary
Hesperia's grading permit does not cover retaining walls: anyone building one in Hesperia, San Bernardino County, needs a separate building permit from the Building Official.
Except as exempted in this section, no grading shall be performed without first having obtained a permit from the Building Official or designee. A grading permit does not include the construction of retaining walls or other structures. A separate permit shall be obtained for each site and may cover both excavations and fills.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 24 Update 2).
Full Breakdown
Hesperia's grading chapter is explicit that a grading permit under HMC § 15.06.030(A) covers excavation and fill work only: it "does not include the construction of retaining walls or other structures." Anyone building a retaining wall in Hesperia therefore needs a separate building permit issued by the Building Official, engineered as required under the state-adopted California Building Code. The city's commercial design guidelines at § 16.16.405 separately tie retaining wall height to the fence and wall height limits set in § 16.20.072, so the permit process and the height limit are handled through different sections of the code.
Violations & Fines
Building a retaining wall without a separate permit is unpermitted construction; the Building Official can issue a stop-work order and require removal or retroactive permitting and inspection.
