Subsection (6) goes further: any retaining wall in a residential or Commercial Development with a grade difference greater than four feet needs a building permit from the Building Inspection Division, with plans approved by the City Engineer and Building Official, who may add drainage requirements.
Violations & Fines
Building or backfilling a retaining wall over four feet of grade difference without a permit is a code violation; the Building Inspection Division can require permitting, engineered plans, or correction of noncompliant walls.
