Pinellas Park requires permits for retaining walls under Land Development Code Article 9, with engineered design typically required when wall height exceeds the Florida Building Code threshold of 4 feet.
Retaining walls in Pinellas Park are governed primarily by the Florida Building Code as adopted under Land Development Code Article 9. A building permit is required from the Building Development Division. Florida Building Code generally requires engineered drawings sealed by a licensed Florida engineer for retaining walls supporting more than 4 feet of unbalanced backfill, or when the wall supports surcharges from structures, slopes, or vehicles. Walls must also comply with the City's Drainage Code (Article 2 of the LDC) so they do not redirect stormwater onto neighboring properties. Setbacks and sight triangle rules from Section 18-1530 also apply when retaining walls function as a fence.
Unpermitted retaining walls may be ordered removed; failure to address drainage or engineering issues can result in code enforcement liens and engineering rework.
