1. Quick‑Look Specs: The Numbers Behind the Box
| Specification | Typical Value | What It Means for You |
|---|---|---|
| External Length | 30 ft (9.14 m) | Slightly longer than a 20‑ft unit, but still short enough for most residential driveways. |
| External Width | 8 ft (2.44 m) | Standard width – fits on most trailers and fits through most garage doors. |
| External Height | 8.5 ft (2.59 m) (standard) 9.5 ft (2.90 m) (high‑cube) | High‑cube gives you ~1 ft extra vertical space – perfect for stacking pallets or a lofted workspace. |
| Internal Length | 28.9 ft (8.81 m) | Usable floor space; subtract a few inches for wall thickness. |
| Internal Width | 7.8 ft (2.35 m) | Same width as a 20‑ft unit—good for shelving, racks, or a small workbench. |
| Internal Height | 7.9 ft (2.39 m) (standard) 8.9 ft (2.71 m) (high‑cube) | Determines how high you can stack items without risking damage. |
| Tare Weight | ~5,000 lb (2,268 kg) | How much the container itself weighs—important for loading capacity calculations. |
| Maximum Payload | 22,000–25,000 lb (10,000–11,340 kg) | The amount you can safely load on top of the container’s own weight. |
| Material | Corten steel (weather‑resistant) | Rust‑proofing for outdoor use; interior may be coated with epoxy for extra protection. |
Pro tip: If you plan to use the container as a living or work space, go for a high‑cube model. The extra headroom makes insulation, wiring, and furniture placement far easier.
2. New vs. Used: Which One Fits Your Budget?
| Feature | Brand‑New Container | Lightly‑Used (1–2 yrs) | Used (3+ yrs) |
|---|---|---|---|
| Price Range | $3,200 – $4,500 | $2,300 – $3,000 | $1,500 – $2,200 |
| Condition | Pristine, no dents, fresh paint | Minor cosmetic wear, fully functional | Possible dents, rust spots, may need repairs |
| Warranty | 1‑year structural warranty (some sellers) | Usually none, but seller may offer limited guarantee | None |
| Delivery Lead‑Time | 2–4 weeks (manufacturing & transport) | 1–2 weeks (stock available) | Same‑day to 1 week (local inventory) |
| Best For | Companies needing a flawless, certified unit for export | Small businesses wanting near‑new quality without the premium | DIY hobbyists, budget‑conscious owners, or those willing to refurbish |
If you’re planning to store valuable equipment or need an ISO‑certified unit for international freight, new is the safest bet. Otherwise, a lightly‑used container often gives the best bang‑for‑buck without compromising structural integrity.
3. Choosing the Right 30‑Foot Container for Your Project
Below is a quick checklist you can print out or pin to your phone. Tick the items that matter most to you, then compare your list against the options you’re eyeing.
- Purpose
Storage, office, pop‑up shop, workshop, or housing? - Ventilation & Insulation
Do you need a pre‑fitted HVAC system or can you add insulation later? - Door Type
Standard swing doors, sliding doors, or a custom opening? - Flooring
Plain steel floor vs. a wooden deck or anti‑slip coating. - Load Capacity
What weight will you be stacking? Check the payload rating. - Location Access
Can your driveway handle a 30‑ft trailer? Is there a crane available? - Budget
Set a hard ceiling; include shipping, permits, and any modifications. - Regulations
Local zoning laws may dictate whether a container can be used as a dwelling.
Example: A freelance graphic designer who wants a quiet home office would prioritize high‑cube height, insulation, and a custom door for easy entry. The same person would likely skip a heavy‑duty floor coating, saving money.
4. Where to Find a 30‑Foot Container: Shopping Channels
| Channel | Typical Price (New) | Delivery Speed | Pros | Cons |
|---|---|---|---|---|
| Manufacturer Direct | $3,200–$4,500 | 2–4 weeks | Fresh paint, warranty, custom options | Higher price, longer lead‑time |
| Local Container Yard | $1,800–$2,800 | Same‑day to 1 week | Quick pick‑up, chance to inspect | Limited inventory, may need transport |
| Online Marketplaces (e.g., eBay, Amazon, ContainerBid) | $2,000–$3,500 | 1–3 weeks | Wide selection, competitive bids | Varying seller reliability |
| Auctions & Liquidations | $1,200–$2,500 | 1–2 weeks (after win) | Lowest prices, bulk options | Uncertainty on condition, minimal warranties |
| Specialty Dealers (e.g., ModPod, BoxHub) | $3,500–$4,800 | 2–4 weeks | Turnkey solutions (insulation, doors) | Premium for added services |
Tip: Whenever possible, ask for a video walkthrough before you finalize the purchase. A quick 2‑minute clip can reveal dents, rust, or missing components that photos might hide.
5. Pricing Snapshot (2025)
| Condition | Approximate Price (USD) | Typical Inclusions |

| New (High‑Cube) | $3,600 – $4,500 | Extra vertical clearance, optional ventilation |

6. Shipping & Delivery: What to Expect
- Transport Method – Most carriers use a flatbed trailer or a low‑boy for containers over 20 ft. If you’re buying locally, a small pickup truck with a trailer may suffice.
- Cost Factors – Distance, fuel prices, and any required permits (e.g., oversized load) determine the final delivery charge. Expect $300–$800 for a 100‑mile delivery.
- Site Preparation – Level the ground, use a rubber mat or concrete pads to avoid moisture damage. Some companies will include a site‑prep service for an extra $200–$400.
- Insurance – Even though containers are steel, they can still be damaged in transit. A $0.10 per $1,000 coverage policy is typical and cheap.
7. Maintaining Your 30‑Foot Container
| Maintenance Item | Frequency | How to Do It |
|---|---|---|
| Exterior Wash | Quarterly | Hose down with water, mild detergent, and dry with a microfiber cloth. |
| Rust Spot Treatment | As observed | Sand the spot, apply a rust converter, then repaint with marine‑grade paint. |
| Door Seal Inspection | Every 6 months | Check for cracks; replace silicone gaskets if needed. |
| Floor Check | Annually | Look for dents or corrosion; consider a polyurethane coating for extra durability. |
| Ventilation Check | Bi‑annually | Ensure vents are not blocked; clean screens. |
A well‑maintained container can easily last 30+ years, making it a solid long‑term investment.
8. Frequently Asked Questions
Q1: Can I legally convert a 30‑foot container into a tiny house?
A: Yes, but you must comply with local zoning rules, building codes, and obtain necessary permits. Many municipalities require insulation, ventilation, and safe egress windows.
Q2: Do 30‑foot containers have a standard door opening size?
A: Most have a 7 ft × 8 ft (2.13 m × 2.44 m) swing door. High‑cube versions may have a slightly larger opening. Custom doors are available at an extra cost.
Q3: What’s the difference between a dry container and a refrigerated (reefer) container?
A: A dry container is uninsulated and suited for general cargo. A reefer has built‑in insulation, a cooling unit, and a sealed door—ideal for perishable goods. Rear‑conversion from dry to reefer is possible but pricey.
Q4: How much weight can I actually load onto the container?
A: The payload is usually 22,000–25,000 lb (10–11 t). Subtract the tare weight (5,000 lb) to get the total allowable gross weight (27,000–30,000 lb). Always stay under the Maximum Gross Weight (MGW) specified by the manufacturer.
Q5: Is it cheaper to buy a container and have it delivered, or to rent one?
A: For short‑term projects (<6 months), renting can be cost‑effective (≈ $150–$200 per month). For long‑term storage or permanent installations, purchasing is usually cheaper after the first year.
Q6: Can I stack containers on top of each other?
A: Yes, if the bottom container is rated for stacking (most ISO containers are). The top container must not exceed the weight limits or interfere with proper ventilation.
Q7: Do I need a permit to place a container on my property?
A: Some jurisdictions require a building permit or a temporary use permit, especially if the container is used as a structure (office, shop, home). Check with your city planning department before you buy.
