Local Project Overview
Deck Construction · St. Johns County, Florida

Almost every new deck or full deck replacement in unincorporated St. Johns County needs a building permit, engineered to meet the region's 130-150 mph wind loads under the Florida Building Code. A 30 percent reduction in general building permit fees, first adopted as pandemic relief, remains in effect until further notice for unincorporated county projects. Plans are reviewed under the St. Johns County Building Department (Growth Management, uni code (IRC Florida Building Cod); apply through St. John’s County Building Department before work begins.

Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).
Code Compliance & Inspections
Because Florida sits in a hurricane-prone zone, the Florida Building Code (FBC) requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
Zoning & Cost Factors
Florida's building codes are some of the strictest in the nation regarding wind resistance and hurricane protection, overriding many local zoning leniencies. Fortunately, Florida maintains relatively builder-friendly regulations, keeping base permit fees competitive.
