Shipping Containers Delivered to Florida

Unlike most states, Florida does not leave its building rules to whoever adopts what locally. Section 553.73 of the Florida Statutes makes the Florida Building Code effective everywhere the moment the commission adopts it: “The initial adoption of, and any subsequent update or amendment to, the Florida Building Code by the commission is deemed adopted for use statewide without adoptions by local government.” A local government may add technical amendments only if they are more stringent than the state code and only after demonstrating a local need beyond the regional variation the code already accounts for, and it may do so no more than once every six months.

That single fact reshapes how you should think about a container here. The permit questions in Florida are not really zoning questions — they are wind and water questions, decided by numbers your building official can look up for your address. What follows is what the code actually turns on, where the two hurricane-zone counties differ from the rest of the state, and what salt air does to steel over a decade. We ship from Lorain, Ohio to any Florida address for a flat $500 per order, normally scheduled 5–10 business days after payment clears.

When a container becomes a “building”

Florida Statutes §553.79 sets the baseline in one sentence: it is “unlawful for any person, firm, corporation, or governmental entity to construct, erect, alter, modify, repair, or demolish any building within this state without first obtaining a permit.” Local enforcement agencies issue, deny and revoke those permits, review plans for code compliance and run the inspection process.

The whole practical question is therefore whether your local building official treats the container as a building. Set on the ground, unmodified, and used as dry storage, many jurisdictions treat it as a temporary or accessory use rather than construction. Cut an opening in it, add electrical service, fix it to a foundation, or put people inside for any length of time, and it stops being ambiguous. Anchoring it against wind can itself be the trigger, because that is a structural attachment.

Ask your building department two specific questions rather than one general one: does this jurisdiction classify a placed storage container as a structure requiring a permit, and does it require engineered anchoring. You will get a clear answer to both, and they may not have the same answer.

Wind is the number that governs

Florida design wind speeds come from ASCE 7-22, which the 8th Edition (2023) Florida Building Code now references. Worth knowing before anyone tells you the numbers have jumped: according to the Florida Building Commission's own fact sheet on the change, wind speeds in ASCE 7-22 changed only in the panhandle area of the state. Peninsula wind speeds are unchanged, and have effectively not changed since the 2010 code. In the western panhandle, speeds increased for Risk Category I, II and III buildings; for Risk Category IV they increased in the western panhandle and decreased slightly in the Big Bend.

The High-Velocity Hurricane Zone

Two counties — Miami-Dade and Broward — sit in the High-Velocity Hurricane Zone, a separate set of provisions written into the code after Hurricane Andrew. Section 1620 of the code's structural chapter sets design wind velocities for the HVHZ explicitly rather than by map lookup:

HVHZ structures are classified as Exposure Category C unless Category D conditions apply, roof live loads are not considered to act simultaneously with wind load, and the section sets a minimum wind design of 15 psf for utility sheds. If you are converting a container into anything occupied in these two counties, budget for engineering and product approvals from the start — the HVHZ is the strictest environment in the state and it is not negotiable by argument.

Everywhere else

Outside the HVHZ the design wind speed is a site-specific value your engineer or building official derives from the ASCE 7-22 maps for your coordinates and the risk category of the structure. Do not use a county-wide figure quoted on a sales page, including this one — get the number for your address.

Anchoring: what “secured” means in practice

An empty 40ft container is a large, light, hollow box with an enormous side area. Full of dense goods it is very hard to move; nearly empty in a named storm it is a different object entirely. That asymmetry is why anchoring comes up in Florida and rarely in, say, Ohio.

There is no single statewide anchoring detail for a placed storage container, because the code addresses buildings rather than shipping containers as a product category. What that means in practice is that your building official decides, and if they require anchoring they will usually require an engineer's design for it — ground anchors, embedded plates or a slab attachment at the corner castings. Get that requirement confirmed before delivery, because retrofitting anchors under a loaded container is far more expensive than pouring for them first. Our permits and zoning guide covers the questions worth asking on that call.

Flood zones decide where the box sits, not whether you may have one

Much of populated Florida is in a mapped flood hazard area, and this is a placement problem more than a permission problem. A container is watertight from above and not from below: floodwater enters at the door sill and around the floor, and a container that floats is a battering ram travelling downstream. Even a foot of moving water will shift an empty unit.

Before you choose a spot, find your flood zone and base flood elevation on the FEMA map for the parcel and call your county or city floodplain administrator — a role distinct from the building department in most Florida jurisdictions. If the site is in a special flood hazard area, expect questions about elevation and about resistance to flotation and lateral movement. Storing anything on pallets rather than on the container floor is sensible everywhere in Florida and essential in a flood zone.

Salt air, humidity and the new-versus-used call

Within a few miles of open salt water, airborne chloride accelerates corrosion of the steel and attacks coatings from cut edges, welds and scratches inward. Corten weathering steel is designed to form a stable protective patina, but that mechanism relies on wetting and drying cycles — persistent chloride and near-constant humidity work against it. A container that would go fifteen years inland can need recoating far sooner on a barrier island.

Florida humidity adds the second problem. Warm moist air enters the box, meets a roof that has cooled overnight, and condenses — the effect commonly called container rain. It drips onto whatever is directly beneath it, which is why people find water damage in a unit that has never leaked.

Two conclusions follow. First, ventilation is not optional here: cross-flow vents plus desiccant, and goods raised off the floor. Second, near the coast the economics of grade shift. A used unit is the right call inland or for short holding periods, but for a permanent coastal installation the extra cost of a one-trip container with intact factory coating usually pays for itself in deferred paint work. Our buyers guide sets out how the grades differ, and if you need genuine temperature and humidity control rather than ventilation, a refrigerated unit is the appropriate purchase.

Local ordinances vary far more than the code does

The statewide code covers construction. It does not cover whether your city wants a container visible from the street, and that is where Florida jurisdictions diverge sharply. Two published examples show the range.

Wilton Manors, in Broward County, devotes an article of its city code (sections 10-99 to 10-101) to portable storage units, defined as any container designed for storage of personal property typically rented for temporary use. A building permit is required before placement and must be displayed on the unit in a weatherproof pouch. No permit is issued for longer than sixty days within a twelve-month period, and only one permit is issued per property in that period. In single-family and duplex districts the unit must sit in the driveway, at least ten feet from the front property line and three feet from the side. Removing or securing the unit during a hurricane warning is the property owner's responsibility. The provision that catches people out is the size cap: total portable storage unit area on a site may not exceed 130 square feet — less than the roughly 160 square foot footprint of a standard 20ft box.

Webster, in Sumter County, goes considerably further. Section 26-1 makes it unlawful to place an ISO freight container, cargo container, shipping container, storage container, semitrailer or similar container on real property in the city to be used as a storage facility. Containers already in business use before the ordinance were declared a nonconforming use, continuable only under conditions including an annual licensing fee, and the licence terminates on a change of business or property ownership or if the storage use is discontinued for sixty consecutive days. The section does not apply where containers are completely enclosed within a building or structure built in compliance with all applicable building codes.

Neither rule is typical of Florida as a whole; that is the point. Look up your own municipal code before ordering rather than relying on what a neighbouring city allows. If you are still deciding on size, the full range runs from 10ft units through 40ft and 45ft boxes, and sending us your site details is the fastest way to sanity-check access before you commit.
