Summary
Polk County treats walls like fences under LDC Section 210: no wall may impede drainage on or adjacent to the site, block public-safety access, or sit in the right-of-way. Structural retaining walls also require a building permit through the Polk County Building Division.
No fence or wall shall be constructed or installed in such manner as to impede drainage on or adjacent to the site.

Full Breakdown
LDC Section 210 applies to both fences and walls. A wall cannot be constructed or installed so as to impede drainage on or adjacent to the site, obstruct emergency access, or encroach into the right-of-way, and on corner lots must stay out of the Section 711 visibility triangle. Retaining walls that hold back earth are structural and require a building permit; precast masonry, concrete, and brick units are permitted with an appropriate building permit under Section 210.B. Engineered walls above the county threshold need engineered plans. Apply through the Polk County Building Division.
Violations & Fines
An unpermitted or drainage-impeding retaining wall can be cited by Polk County Code Enforcement, with fines and liens available under Florida Statutes Chapter 162, and may have to be corrected or removed.
