Soffit and fascia are two different parts with two different jobs, and confusing them is why quotes vary so much. Permit in Orange County: depends on the scope. Orange County publishes no soffit/fascia exemption and its no-permit list is closed. The full answer and its source are below, with the code requirements and mistakes that trip up Orlando homeowners.

Key facts before you start

Soffit and fascia are two different parts with two different jobs, and confusing them is why quotes vary so much. The fascia is the vertical board at the roof edge that the gutter hangs on and that the roof deck terminates against; the soffit is the horizontal underside of the overhang between the fascia and the wall. Neither is decorative trim in Florida — FBC-R R704.1: "Soffits and their attachments shall be capable of resisting wind loads specified in Tables R301.2(2) and R301.2(3) for walls using an effective wind area of 10 square feet," i.e. the underside of your eave is engineered to a wall's wind load, and R703.1.2.1 sends every exterior soffit to that section. Fascia failure is usually a water problem — a leaking gutter, a missing drip edge, or a roof edge that has been draining behind it. Soffit failure is usually a ventilation or wind problem. A quote that does not say which one it is replacing is not a quote.
The soffit is half of your attic's ventilation, and the code specifies how much. FBC-R R806.2: "The minimum net free ventilating area shall be 1/150 of the area of the vented space," reducible to 1/300 when the vents are split correctly between high and low. The split is the part people get wrong: upper ventilators go "not more than 3 feet (914 mm) below the ridge or highest point of the space, measured vertically" and carry 40 to 50 percent of the required area, while "the balance of the required ventilation provided shall be located in the bottom one-third of the attic space" — that bottom third is the soffit. Ridge vents with blocked or solid soffit have no intake, so the system does not work.
Net free area is not the size of the hole, and the units are the trap. A vent's rated NFA subtracts the louvers and the insect screen, so a 16-inch vented panel does not deliver 16 inches of ventilation. Manufacturers then publish the figure in units that do not compare: Gentek rates its Sequoia Select vinyl soffit at "10 square inches of ventilation per linear foot," others quote square inches per square foot or per panel, and most panels in that same catalog publish no NFA figure at all. Get the number AND its unit in writing, convert them to one unit, multiply by the run you are installing, and check it against the 1/150 or 1/300 requirement before assuming vented panels alone are enough.
Screening is a code detail with a Florida reason. FBC-R R806.1 requires ventilation openings to have "a least dimension of 1/16 inch (1.6 mm) minimum and 1/4 inch (6.4 mm) maximum," and anything larger has to be screened to that same range. The maximum keeps out wasps, bats and rodents; the 1/16-inch minimum exists so the mesh does not blind itself with dust and lint and quietly cut your ventilation to nothing. A soffit that has been screened with ordinary window screen is a common defect that looks fine and vents poorly.
Florida writes down how the panels and the fascia are actually fastened, and it is exactly what a cheap job skips. FBC-R R704.2.1: soffit panels take corrosion-resistant fasteners and "shall be fastened at both ends to a supporting component such as a nailing strip, fascia or subfascia component," and "Where the unsupported span of soffit panels is greater than 12 inches, intermediate nailing strips shall be provided ... unless a larger span is permitted in accordance with the manufacturer's product approval specification." Panels and fascia covers must both go up "in accordance with the manufacturer's product approval specification and limitations of use" — so ask which Florida product approval the installer is working to, because that document, not habit, sets the legal span. Corners are specified too: on hips the fascia bends around and runs at least 12 inches past the corner with the next section lapping it at least 3 inches (R704.4); on gables it is wrapped/tabbed at least 1 inch past the corner, two face nails into a 2x4 subfascia and three into 2x6 or larger (R704.5).
In Florida the soffit is a wind and water-intrusion path, not just trim, and the failure is documented rather than theoretical: FEMA's Coastal Construction Manual (P-55) captions a post-storm photo "When the soffits blew away in 140 to 160 mph hurricane winds, wind-driven rain was allowed to enter the attic." The roof can hold and the house still takes water from above, because the soffit opens directly into the attic. So when soffit is replaced, ask how the panels are secured into the channel at both ends, whether the J-channel and F-channel are fastened to solid framing rather than to the old rotted board, and whether anything is being reused. This is also why the insurance conversation on the ceiling-stain guide matters — water that entered through the soffit reached the interior without any opening in the roof.
Fix the water path and the substrate before new material goes up, and settle the permit question first. Aluminum and vinyl do not rot, which is the usual reason to switch, but they do not fix the cause: whatever soaked the original wood — a gutter draining behind the fascia, a missing or short drip edge, an overflowing gutter dumping on the eave — is still there behind the new skin where you cannot see it. Fascia cover is a wrap, not a structural member; it fastens to the board behind it, so covering a soft board hides the damage and gives the fasteners nothing to hold. Anything soft comes off first, and rot that reached the rafter tails or roof sheathing is a roofing repair and a different trade (cannot tell rot from an insect? see the termite and wood-rot guide). On permits, Orange County's guide says "A replacement roof on my home? Yes, you do need a roof permit" but never lists soffit or fascia and warns it "is intended for reference purposes only and is not complete or exhaustive" — so confirm your scope with Building Safety at 407-836-5550, and note an "Orlando" address may be City of Orlando rather than unincorporated Orange County.

The permit answer

Depends on the scope. Orange County publishes no soffit/fascia exemption and its no-permit list is closed. Like-for-like trim repair is commonly treated as maintenance; work that reaches structural members (rafter tails, sub-fascia) or a whole elevation belongs in permit territory — confirm your scope with the county first.
