Full Breakdown
401 requires a permit for work covered by 'this building code and the Florida Building Code,' with only 'ordinary minor repairs' exempted if the Building Official approves and the work doesn't violate the Florida Building Code. 409(a) lists the fee categories the Building Inspection Division charges for construction; item (4) groups retaining walls with masonry walls, water towers, storage tank foundations, cell towers and similar site work not built inside a building, and sets the fee at a rate per $1,000 of estimated construction cost up to $500,000, with a different per-$1,000 rate above that threshold, plus a Resource Management Fee, Landscape Fee, Development Services Fee and Construction and Demolition Debris Fee layered on top.
112. Because the Ordinance Code folds retaining walls into the Florida Building Code permit process rather than writing a separate local height or engineering threshold, the design standards, including when a sealed engineering plan is required, come from the adopted Florida Building Code itself, not from a Jacksonville-specific number. 1204, Ordinance Code, on top of the standard building permit.
Violations & Fines
Building or altering a retaining wall without the required Section 320.401 permit exposes the owner and contractor to the City's standard building-code enforcement: a stop-work order from the Building Official, referral to the Municipal Code Compliance Division, and liability for the permit and inspection fees regardless of when the work is discovered. A wall built in a regulated floodway without meeting the added fill limitations of Section 652.1204 is a separate violation of Section 652.1603.
