Summary
Seminole County has no separate retaining-wall ordinance; walls are regulated under the same fence-and-wall provision, LDC Sec. 30.14.19. A building permit is required, height is measured from the higher-elevation lot on sloped sites, and no wall may project beyond the property line or into a sight triangle.
A building permit is required for any fence or wall to be erected, replaced, or needs major repair... Where grade elevations along adjoining properties differ, fence/wall height shall be measured from the finished ground floor elevation of the property having the higher ground floor elevation.

Full Breakdown
Seminole County's LDC 30.14.19 applies to 'any fence or wall,' so retaining and garden walls follow the same rules. A building permit is required to erect, replace, or majorly repair a wall (subsection a), and the application must include a certified survey. Residential wall height limits mirror fences: 4 feet in the front and side-street setbacks and 6 feet 6 inches within side and rear setbacks (subsection b); anything taller needs Board of Adjustment approval (subsection q). Critically, where adjoining grades differ, subsection (p) measures height from the finished floor elevation of the higher property, so a retaining wall cannot be used to raise grade and then stack a full-height fence for extra height.
Violations & Fines
Building a wall without a permit or exceeding the height limit without Board of Adjustment approval is a code violation. Seminole County Code Enforcement can issue stop-work and removal orders, with civil penalties available before the Special Magistrate under F.S.
