Is an Engineer Stamp Required for My Deck Project in Florida?

Florida cities — Miami, Tampa, Orlando, Jacksonville — review structural drawings for decks under the Florida Building Code, and the PE seal is the standard requirement for non-prescriptive decks. The seal must show the engineer's name, Florida PE number, and date, and the engineer must be in responsible charge of the engineering. Elevated decks, pool decks, and decks with roofs are treated the same at the structural level. Owner-builders don't escape the requirement: the building department asks for the seal regardless of who drafted the plans.

The engineer reviews the deck plan and elevations, designs the footings for sandy soils and the high water table, sizes beams, joists, and posts, and checks the ledger connection and the lateral system for hurricane wind demand per the Florida Building Code. The high-velocity hurricane zone gets extra scrutiny on connections and opening protection. Flood elevation is checked where triggered. Bring the site survey, the geotechnical report, and the deck plans. Wind design is the item most deck plans miss.

Use this checklist before engaging an engineer for your deck: • Engineer of record holds an active Florida PE license, verifiable on the state roster • Dimensioned deck plan and elevations ready for structural review • Site survey showing setbacks, easements, flood zone, and existing structures • Hurricane wind design verified per the Florida Building Code • Flood elevation verified where triggered • Ledger connection to the house detailed and verified • Engineer confirms they'll respond to plan-check corrections on sealed sheets • Seal shows name, Florida PE number, and date on every sealed sheet
