Frequently Asked Questions

We ship containers to locations across the United States via tilt-bed transport trucks. Once your order is confirmed, delivery is typically scheduled within 3 to 5 business days based on your geographic location. All that is required on your end is a level, truck-accessible drop-off spot — such as a driveway, paved lot, or cleared patch of ground. You do not need any special unloading machinery. For a quick cost estimate, simply enter your ZIP code into our online delivery calculator.

The cost of delivery is determined by how far your location is from the closest warehouse in our distribution network. To get an instant price estimate, plug your ZIP code into our online calculator. You can also reach out to us at [email protected] for a precise quote. Our delivery network covers 191 cities across all 51 states.

Most deliveries are completed within 3 to 5 business days after your order is confirmed and payment is received. Delivery timelines depend on your distance from the nearest container depot, carrier availability, and local scheduling demand. Customers located near major port cities or distribution hubs — such as Houston, Los Angeles, Chicago, or Savannah — often receive their containers on the faster end of that window. Rural or remote locations may require additional transit time. You will receive a confirmed delivery window ahead of your drop-off date so you can prepare your site. If you have a hard deadline, let our team know at the time of purchase and we will do our best to accommodate your schedule.

Your delivery site should feature a flat, even surface with enough space for a tilt-bed truck to access and operate. These trucks measure approximately 60 feet in length and require adequate room to turn and position. Suitable foundation options include gravel pads, poured concrete slabs, or firmly packed soil. To promote airflow and proper drainage, we suggest setting railroad ties or concrete footings beneath each corner of the container. Additionally, verify that no overhead power lines or tree limbs obstruct the delivery path. If you have any concerns about your particular site, send us an email and we will help you with a placement plan.

Choosing the right spot for your container is critical for a smooth delivery and long-term satisfaction. Select a level area with good drainage — avoid low spots where rainwater collects, as standing water under a container accelerates corrosion. You will need at least 100 feet of straight-line clearance for the delivery truck to approach and place the container, including overhead clearance for power lines and tree branches (minimum 14 feet high). Position the container doors so they face a direction that is convenient for daily access and does not block driveways, walkways, or sight lines. Check your local setback rules — most municipalities require containers to be a minimum distance from property lines, easements, and structures, often 5 to 15 feet depending on the zone. If possible, orient the container on a slight forward slope so any rain that enters when the doors are open will drain out naturally.

Our containers are available in four distinct condition tiers:

• One-Trip — Virtually brand new, having completed just a single overseas journey. Expect only minor cosmetic blemishes. The top choice for container homes and high-end applications.
• Cargo Worthy (CWO) — Carries an active CSC certification, making it eligible for international ocean freight. Some surface oxidation and dings are common. Offers outstanding overall value.
• Wind & Water Tight (WWT) — Completely sealed against the elements, though no longer approved for maritime transport. The most economical option for secure on-site storage.
• As-Is — No warranty included. Could show visible wear or slight water intrusion. A budget-friendly pick for low-priority storage needs or creative DIY builds.

Cargo Worthy (CWO) units maintain a current CSC (Convention for Safe Containers) certification, which means they are approved for overseas ocean shipping. While they may exhibit some rust and minor denting, their structural soundness is fully intact.

Wind & Water Tight (WWT) units provide complete protection from rain and wind but no longer carry ocean transport certification. For buyers who only require a container for storage purposes, selecting a WWT unit can save several hundred dollars while still delivering full weather resistance.

Absolutely. Shipping containers serve as outstanding structural foundations for houses, guest cabins, and accessory dwelling units (ADUs). For residential construction, we suggest choosing One-Trip or Cargo Worthy units due to their excellent structural condition. The 40ft High Cube model is especially popular for housing projects, providing roughly 302 square feet of usable floor area with a 9'6" interior ceiling height — plenty of room for comfortable living once insulation and interior finishes are installed. Before beginning your build, be sure to reach out to your local building and planning department to confirm permit and building code requirements.

Our inventory includes four standard container sizes:

• 20ft Standard — Dimensions of 8’ wide by 8'6" tall by 20’ long, yielding approximately 148 sq ft of usable space. A solid choice for home storage and compact projects.
• 20ft High Cube — Identical length and width, but with an additional foot of height (9'6" total). Best suited for applications requiring extra vertical clearance.
• 40ft Standard — Measures 8’ wide by 8'6" tall by 40’ long, offering roughly 302 sq ft. Well suited for heavy machinery, vehicle storage, or large-scale commercial use.
• 40ft High Cube — Our best-selling option. Standing 9'6" tall, it provides the greatest storage capacity. A favorite for converted offices, workshops, and container residences.

The primary difference is height: a Standard container has an exterior height of 8'6" (roughly 7'10" inside), while a High Cube container stands 9'6" tall (approximately 8'10" inside). That extra foot of interior headroom makes a significant difference for anyone planning to work, live, or spend time inside the container — you can comfortably install drop ceilings, overhead lighting, insulation, and ductwork without feeling cramped. High Cube models are the preferred choice for container offices, workshops, homes, and retail conversions where ceiling height affects comfort and usability. Both Standard and High Cube containers share the same 8-foot width and are available in 20ft and 40ft lengths. The price premium for a High Cube is typically modest — often just a few hundred dollars more than the Standard equivalent — making it an easy upgrade for most projects.

The empty (tare) weight of a shipping container varies by size and type. A 20ft Standard container weighs approximately 5,070 lbs (2,300 kg), a 40ft Standard comes in around 8,380 lbs (3,800 kg), and a 40ft High Cube weighs roughly 8,600 lbs (3,900 kg) due to the extra foot of steel in its walls and frame. These weights are important to know for two reasons: delivery logistics and foundation planning. Your delivery site needs to support a fully loaded tilt-bed truck that can weigh 40,000+ lbs combined, and your foundation — whether concrete piers, gravel pad, or railroad ties — must be rated to handle the container’s weight plus whatever you plan to store inside. If you are placing a container on a rooftop or elevated structure, consult a structural engineer to verify load capacity.

Used shipping container prices vary primarily by size and condition. A 20ft container typically ranges from $1,200 to $5,500, while a 40ft container runs between $1,800 and $7,500. One-Trip (near-new) units command the highest prices due to minimal wear, while Wind & Water Tight (WWT) containers offer a solid middle ground — structurally sound and fully sealed at a more affordable price point. As-Is units are the most budget-friendly but may have dents, surface rust, or compromised seals, making them best suited for basic dry storage in covered areas. Market conditions, your delivery location, and current inventory levels also influence final pricing, so we recommend requesting a free quote for the most accurate number.

Several key factors determine the final cost of a shipping container. Condition is the biggest driver — a One-Trip unit can cost two to three times more than an As-Is container of the same size. Size matters as well; 40ft and High Cube models carry a premium over standard 20ft units. Location plays a significant role because containers are more plentiful near major port cities like Houston, Los Angeles, and Savannah, which keeps local prices lower. Delivery distance from the nearest depot to your property adds to the total cost, and nationwide supply and demand fluctuations — driven by global shipping volume — can cause prices to shift seasonally. To lock in the best rate, we recommend requesting a quote as soon as you are ready to buy.

For most buyers, a WWT (Wind & Water Tight) 40ft High Cube delivers the best bang for your buck. You get roughly 302 square feet of secure, weatherproof storage with a generous 9'6" ceiling height — enough room to stack pallets, park a vehicle, or set up shelving systems. The WWT grade means the container is certified to keep rain, wind, and pests out, yet it costs significantly less than a One-Trip unit because it shows normal cosmetic wear from its ocean shipping career. The extra foot of height in the High Cube model adds meaningful headroom compared to the standard 8'6" version, all for a modest price increase. If you need less space, a WWT 20ft Standard is another excellent value option that fits easily on most residential lots.

Yes, we want you to feel confident in your purchase. We provide detailed photo packages of the specific container assigned to your order so you can review its condition before finalizing payment. If you prefer an in-person look, depot visits can be arranged by appointment at select locations across the country — just let your sales representative know and they will coordinate access. Keep in mind that our containers are graded to industry standards (One-Trip, CWO, WWT, As-Is), and each grade comes with clear expectations regarding cosmetic wear and structural integrity. For customers who cannot visit in person, our photos and transparent grading system ensure there are no surprises when your container arrives.

We currently accept wire transfers, cashier’s checks, and business checks. Full payment must be received prior to scheduling delivery. Although we do not offer in-house financing at this time, we are happy to supply a comprehensive invoice that you can present to your bank or lending institution to arrange your own financing. Reach out to us via email to discuss any special payment arrangements.

We offer a 24-hour cancellation window from the time of order confirmation, allowing you to cancel for a full refund before your container is dispatched. Once a container has been loaded for delivery or placed on your property, returns are not accepted due to the significant logistics costs involved in transporting heavy steel units. If your container arrives with damage that was not disclosed or that occurred during transit, you must file a damage claim within 48 hours of delivery — our team will work with you to resolve the issue promptly through repair, replacement, or credit. We encourage all customers to review their order details, photos, and condition grade carefully before confirming their purchase.

Shipping containers are incredibly versatile and can serve dozens of purposes beyond basic storage. The most popular uses include secure on-site storage for tools, equipment, furniture, and seasonal inventory, as well as workshops, home offices, and art studios where the steel shell provides a quiet, weatherproof workspace. Containers are also widely used on construction job sites for tool lockup and portable offices, on farms and ranches for equipment and feed storage, and as retail pop-up shops, food stalls, and event spaces. Homeowners use them for extra garage space, storm shelters, and even full container homes. With simple modifications like roll-up doors, windows, insulation, and electrical wiring, a shipping container can be adapted to nearly any residential, commercial, or agricultural application you can imagine.

Absolutely — container offices are one of the fastest-growing uses for shipping containers, and they can be set up for a fraction of the cost of traditional construction. A 40ft High Cube is the most popular choice, providing roughly 320 square feet of usable space with a comfortable 9'6" ceiling height that feels like a standard room. Key modifications include spray foam insulation (R-19 or higher for climate control), a mini-split HVAC system for heating and cooling, and professional electrical wiring for lighting, outlets, and data connectivity. You will also want to cut in windows for natural light and add a commercial-grade entry door. Most jurisdictions require a building permit for a permanent container office, especially if it will have plumbing or electrical service, so check with your local building department before beginning your build.

Yes, shipping containers make excellent garages and workshops, especially the High Cube models which offer 9'6" of interior height — enough clearance to work comfortably on vehicles, install overhead lighting, or hang wall-mounted tool racks. For a workshop, consider adding LED shop lights, a ventilation fan or louvered vents to manage fumes and humidity, and durable epoxy or rubber flooring to create a clean, level work surface. A roll-up door on one end makes it easy to move large equipment or vehicles in and out. Many customers also install workbenches, pegboard walls, and 240V outlets for power tools. A 40ft container gives you roughly the same footprint as a single-car garage, and two units placed side by side can rival a full two-car setup at a significantly lower cost than a stick-built structure.

Shipping containers are a staple on farms and ranches across the country because they are tough, weatherproof, and rodent-resistant — exactly what you need to protect valuable equipment and supplies. Common agricultural uses include equipment and tractor storage, feed and grain bins, tack rooms for saddles and riding gear, and chemical or fertilizer lockup that keeps hazardous materials secure from animals and weather. Placed strategically, a container can also serve as an effective wind break or livestock shelter during harsh seasons. The 40ft Standard is the most popular choice for farm use because it offers maximum floor space at a practical price point, though a 20ft unit works well for smaller operations or remote pasture storage. Because containers sit on their own steel frame, they can be placed on compacted gravel or even level ground without a permanent foundation, making them easy to relocate as your operation grows.

Construction companies rely on shipping containers because they provide secure, portable, and cost-effective storage and workspace that can move from job site to job site. A container on-site eliminates the need to transport expensive tools and materials back to a warehouse each day — 14-gauge Corten steel walls and a heavy-duty lock box make them virtually theft-proof. Many contractors use a 20ft container for tool and equipment lockup and a 40ft High Cube as a temporary job site office, complete with a desk, plan table, and electrical hookup. Unlike renting a mobile trailer, purchasing a container is a one-time investment that pays for itself within a few months and can be resold when the project wraps up. Containers are also easy to relocate on a standard tilt-bed truck, making them ideal for companies that work across multiple sites throughout the year.

Yes — shipping container pop-up shops, cafes, and retail stores are one of the hottest trends in commercial real estate, offering a unique aesthetic and dramatically lower buildout costs compared to traditional storefronts. A 20ft container is the most common size for a single retail unit, while a 40ft High Cube provides enough space for a full boutique or food service operation with counter seating. Popular modifications include roll-up serving windows, fold-down awnings, custom exterior paint and branding, and interior buildouts with display shelving, lighting, and point-of-sale wiring. You will need a local business permit and building inspection in most jurisdictions, especially if you plan to serve food or connect to utilities. Container retail spaces are also popular at farmers markets, festivals, breweries, and food truck parks where their industrial look and portability are major selling points.

A well-maintained shipping container can last 25 years or more in stationary storage use, and many containers remain structurally sound for 50+ years with periodic upkeep. This exceptional durability comes from Corten steel (also known as weathering steel), which forms a self-healing rust patina that protects the underlying metal from further corrosion — unlike regular steel that rusts through over time. Containers that were used in active ocean shipping for 10 to 15 years still have decades of life left when retired to on-site storage or conversion projects. To maximize lifespan, keep the roof clear of standing water, touch up deep scratches with a zinc-rich primer, and lubricate door hinges and gaskets annually. One-Trip containers, having made just a single ocean voyage, offer the longest remaining service life and are the best choice if longevity is a top priority.

Shipping containers are engineered to endure some of the harshest conditions on Earth, including violent ocean storms with sustained winds exceeding 100 mph. Their rigid steel frame is ISO-rated to be stacked 9 containers high when fully loaded, which translates to extraordinary structural strength against lateral wind forces and flying debris. In hurricane-prone and tornado-prone regions, containers are frequently used as storm shelters and safe rooms because of this inherent toughness. However, an unanchored container can shift or even overturn in extreme wind events, so bolt-down anchoring to a concrete foundation or helical piers is strongly recommended for permanent installations. Many customers in coastal areas and tornado alleys use containers specifically because they outperform wood-frame sheds and metal outbuildings in severe weather scenarios. For maximum safety, consult a local engineer about anchor spacing and wind load requirements specific to your region.

Shipping containers are among the most secure portable storage options available. The walls, floor, and ceiling are constructed from 14-gauge Corten steel — thick enough to resist cutting tools, pry bars, and forced entry attempts that would easily compromise a standard shed or garage. Each container features heavy-duty cam-lock door bars and tamper-resistant hinges that are welded directly to the door frame, making them nearly impossible to remove. Most containers come equipped with a lock box — a welded steel shroud that encloses your padlock and prevents bolt cutter access. For added security, we recommend using a high-security disc lock or hidden shackle padlock such as those made by ABUS or Master Lock. Some customers go further by adding motion-sensor lights, trail cameras, or GPS tracking devices for remote or unattended locations.

Corten steel — formally known as weathering steel — is a special alloy containing copper, chromium, and nickel that forms a stable, protective rust layer (called a patina) when exposed to the elements. Unlike ordinary carbon steel that rusts progressively until it corrodes through, Corten’s patina acts as a shield that slows further oxidation by up to 80%, effectively making the container self-protecting without the need for paint or coatings. This is why shipping containers can sit outdoors for 50 years or more and remain structurally sound. The characteristic reddish-brown patina also gives containers their iconic industrial look, which many architects and designers intentionally showcase. If you prefer a different appearance, Corten steel accepts paint readily — just apply a rust-inhibiting primer first for best adhesion. Every container we sell is built with Corten steel, ensuring long-term durability regardless of condition grade.

• One-Trip & Cargo Worthy — Protected by a 5-year structural warranty that covers frame integrity and weatherproofing.
• Wind & Water Tight — Includes a 3-year structural warranty.
• As-Is — Offered with no warranty coverage.

Every container (aside from As-Is units) also comes with our 30-day satisfaction swap guarantee. Should the container fall short of your expectations, we will exchange it for another unit at no additional cost within the first 30 days of delivery.

Shipping containers can be modified in almost any way you can imagine, making them one of the most adaptable building blocks available. The most popular modifications include cutting in windows and man doors, adding roll-up doors for drive-in access, and installing spray foam insulation with interior wall framing for climate control. Electrical wiring for lighting, outlets, and breaker panels is a common upgrade, as are mini-split HVAC systems for year-round heating and cooling. Cosmetic options include custom exterior paint, interior shelving and workbench builds, epoxy flooring, and ventilation fans or louvers for air circulation. More advanced builds incorporate plumbing, bathroom pods, kitchenette buildouts, and even rooftop decks. Whether you are doing a simple DIY storage upgrade or a full commercial buildout, the steel shell of a container provides a strong, weatherproof canvas to work with.

Yes — painting a shipping container is one of the simplest and most impactful modifications you can make. Start by cleaning the surface with a pressure washer and removing any loose rust or flaking paint with a wire brush or grinder. Apply a rust-inhibiting primer (zinc-rich or DTM primer works best on Corten steel) to the entire exterior, then follow up with two coats of industrial-grade exterior paint — acrylic latex or polyurethane enamel are both excellent choices for durability and UV resistance. Most standard colors are available off the shelf at any paint supplier, and we can also arrange custom color matching if you need your container to match existing buildings, brand colors, or HOA requirements. A quality paint job not only improves curb appeal but also adds an extra layer of corrosion protection, extending the life of your container even further.

Yes, windows and doors can be added to any shipping container with the right tools and technique. Openings are cut into the corrugated steel walls using a plasma cutter or reciprocating saw, and the cut edges are framed with welded steel tubing called window bucks to maintain structural integrity and provide a mounting surface. Standard residential windows, sliding glass doors, commercial storefronts, and man doors can all be installed once the opening is properly framed and sealed. It is important to add flashing and weatherproof sealant around each opening to prevent water intrusion. For DIY builders, pre-cut container window and door kits are available that simplify the framing process. If you prefer a turnkey solution, we can arrange professional modification services so your container arrives ready to use with openings already cut and finished.

The best insulation method depends on your budget, climate, and whether you plan to hire a professional or DIY. Closed-cell spray foam (ccSPF) is the top choice for containers because it delivers the highest R-value per inch (approximately R-6.5 per inch), acts as a vapor barrier, and bonds directly to the corrugated steel walls without leaving air gaps that cause condensation. Rigid foam boards like EPS or XPS (R-3.8 to R-5 per inch) are a more affordable option that can be glued or mechanically fastened to the walls and then covered with plywood or drywall. For a DIY-friendly approach, InSoFast panels are pre-engineered rigid foam panels with built-in furring strips that snap together for quick installation and easy drywall finishing. Regardless of method, insulating the roof and floor — not just the walls — is critical for effective climate control, since the steel roof absorbs significant solar heat and the corrugated floor can transfer ground cold.

Whether you need a foundation depends on how you plan to use your container and how long it will stay in place. For temporary or short-term storage, a simple base of railroad ties, compacted gravel, or concrete blocks placed under the four corner castings is usually sufficient — this keeps the container level and elevated above ground moisture. For permanent installations, especially those involving modifications like offices or living spaces, a more robust foundation such as concrete piers, a concrete slab, or helical piles is recommended to meet building codes and ensure long-term stability. The container’s built-in steel frame distributes its weight through the four ISO corner castings, so full-perimeter footings are typically not required. On sloped sites, piers of varying heights can level the container without expensive grading work. Consulting your local building department early in the planning process will clarify exactly what foundation type is required for your intended use and zoning district.

Yes, you can place a shipping container directly on grass or dirt for temporary use, but taking a few precautions will prevent problems down the road. Without a proper base, the container’s corner castings can sink into soft ground over time — especially after heavy rain — causing the unit to settle unevenly and making the doors difficult to open. For the best results on unpaved surfaces, lay down a 4- to 6-inch compacted gravel pad or set pressure-treated railroad ties under the container’s four corners to distribute the weight and promote drainage. This small investment keeps the container level, allows air circulation underneath to reduce condensation and moisture buildup, and prevents the steel floor from sitting in direct contact with damp soil. If the placement is truly temporary (a few weeks to a few months), bare level ground will usually work fine, but always check soil conditions and drainage before your delivery date.

Permit regulations differ from one jurisdiction to another throughout the United States. As a general rule, rural areas and unincorporated zones tend to impose minimal restrictions on placing containers on private land. However, many municipal and county governments do require a zoning or building permit — particularly if you intend to convert the container into a habitable space or workspace. We strongly suggest reaching out to your local zoning or planning office prior to making a purchase. Our team is also available to assist you in navigating the permitting process.

Permit requirements vary significantly by city, county, and state, so there is no one-size-fits-all answer. In most residential areas, placing a shipping container as a permanent accessory structure requires a zoning permit or building permit — your local planning or building department can confirm the specifics in a quick phone call. Many jurisdictions allow containers for temporary use (30 to 90 days) during a move, renovation, or construction project without a permit, but anything beyond that window typically triggers permit requirements. Rural and agricultural-zoned properties tend to have the fewest restrictions, and many counties in these zones allow containers outright with no permit at all. When applying for a permit, you may need to submit a site plan showing the container’s location relative to property lines, setbacks, and existing structures. We recommend checking with your local authorities before placing your order so there are no surprises after delivery.

This depends entirely on your HOA’s Covenants, Conditions & Restrictions (CC&Rs), which govern what structures are allowed on your property. Many HOAs restrict or prohibit shipping containers due to aesthetic concerns, particularly in suburban neighborhoods where uniformity is emphasized. However, some HOAs allow temporary placement during home construction, remodeling, or moving — typically for 30 to 90 days with board approval. If you want a permanent container on your property, one strategy that has worked for many homeowners is cladding the container with wood siding, stucco, or composite panels so it blends in with surrounding architecture and no longer looks like an industrial steel box. Before purchasing, pull out your CC&Rs and review sections on outbuildings, accessory structures, and temporary storage — then contact your HOA board to discuss your plans. Getting written approval in advance will save you from potential fines or forced removal later.

Yes — placing a shipping container on commercial or industrial-zoned property is generally much easier to permit than on residential land. Most commercial and industrial zones already allow outdoor storage, accessory structures, and temporary buildings, which shipping containers typically fall under. You will still need to verify compliance with your local zoning ordinance, including setback distances from lot lines and any screening or fencing requirements that may apply. For containers used as job site offices, retail units, or modified structures with electrical or plumbing, a building permit and inspections are usually required just as they would be for any commercial buildout. Many businesses — from auto shops and landscaping companies to retailers and restaurants — use containers on their commercial lots with minimal permitting friction. Contact your city or county planning department with your specific address and intended use, and they can typically give you a clear answer within a single visit or phone call.

Shipping containers are low-maintenance by design, but a simple annual routine will keep yours in top condition for decades. Inspect the roof at least once a year for dents, debris, or areas where water pools — standing water is the number one cause of premature corrosion, and any low spots should be filled or patched with a roofing sealant. Touch up scratches, chips, and bare metal with a zinc-rich cold galvanizing primer (brands like ZRC or Rust-Oleum Cold Galvanizing Compound work well) to stop rust before it spreads. Lubricate the door hinges, cam bars, and locking rods with a silicone or white lithium grease to keep the doors swinging freely and prevent them from seizing. Check the rubber door gaskets annually and replace them if they become cracked or compressed, as worn seals allow moisture and pests inside. With these basic steps — roughly 30 minutes of work per year — your container will stay weathertight and functional for its full 25- to 50-year lifespan.

The good news is that shipping containers are built from Corten steel, which naturally forms a protective rust patina that dramatically slows further corrosion — so a certain amount of surface oxidation is actually the material working as designed. To prevent problematic rust, focus on areas where the protective patina cannot form properly: dents and low spots on the roof where water pools, cuts and deep scratches that expose bare steel, and contact points where the container touches the ground or another metal surface. Treat any exposed metal promptly with a zinc-rich primer such as ZRC Cold Galvanizing Compound, which chemically bonds to the steel and mimics galvanized protection. In humid or coastal climates, consider applying a full exterior ceramic coating or industrial paint system for an extra layer of defense against salt air and persistent moisture. Keeping the container elevated on gravel, railroad ties, or concrete piers also helps by promoting airflow underneath and preventing ground moisture from wicking into the floor frame.
