If that wall carries any load — and many interior walls do — yes. An engineer has to calculate what replaces the load path (typically a header or beam) and verify the foundation below can handle the redistributed load.

Under Florida law, any structure over three stories or 50 feet tall, or certain large assembly spaces, qualifies — and that triggers a required structural inspection plan and a specially qualified inspector beyond normal building department review.

The architect designs layout, spaces, and the building envelope; the engineer produces sealed calculations and drawings proving the structure can physically carry the loads that design creates, including wind loads specific to South Florida.

Under the current Florida Building Code, calculations follow ASCE 7-22 methodology, accounting for the county's design wind speed, building height, exposure category, and roof geometry, producing separate figures for the overall structure and for individual components like windows and roof fasteners.

It's a structural element — often specific connections or shoring plans — finalized after initial permit submission because it depends on fabricator or subcontractor details not yet available, and it gets reviewed separately once those details are ready.

Often yes for the roof-to-wall connections and fastening pattern, especially in HVHZ areas, even if the underlying roof structure itself isn't changing — the fastening and uplift resistance are engineered separately from cosmetic roof covering choices.

It gets caught at coordination review before submission if the team is managing it properly; if it's not caught, it surfaces as a plan review correction requiring revised drawings from one or both disciplines, adding a review cycle.

The engineer of record bears professional responsibility for their sealed calculations and drawings, and the contractor is responsible for building to those specifications — which is part of why sealed, coordinated documentation matters beyond just clearing permit review.
