Busting Myths: Old Stereotypes About Shipping Container Homes That No Longer Hold Up

S.I. Container Builds' shipping container homes are the future of offsight modula construction. Here's why.

Stereotype #1: “It Doesn't Make Sense.”

The Myth: Container homes are steel and cold and regulations demand that you must build walls on each side.

The Reality: Steel is the best conductor of temperature for home build materials. Couple that with building to code using the correct R-value insulation in the walls, ceilings, and floors makes for an energy efficient perfectly tempered unit.

Stereotype #2: “They’re Too Expensive and Inspectors Hate Them”

The Reality: Actually, we are finding that not only are we able to build about 8-10% cheaper compared to other types of buildings, but we provide a faster ROI so that you can start making money within a couple of months vs a year. In the past, inspectors were weary of container builds because they didn't know the ins-and-outs of this newer substrate. Nowadays, they are educated. We have dedicated time to get them up to speed. Our containers are single-trip and that also provides peace of mind to inspectors. And, we follow all building codes which also helps with the process. Once they see that we build things properly they become our partners and even our advocates! Containers have been repurposed for decades in other countries and that has caught on here in the US. Many build companies are turning to this abundant, sustainable material and are turning them into spectacular dwellings that will last a lifetime.

Stereotype #3: “They’re Tiny and Claustrophobic”

The Myth: A single container is only 8 feet wide and just over 9 feet tall—how could anyone live comfortably in that?

The Reality: While some container homes are compact by design (hello, tiny home movement!), they can also be modular. Builders now combine two, four, or even ten containers to create expansive layouts with multiple bedrooms, high ceilings, open floor plans, and ample natural light. Vertical stacking and strategic cutouts allow for multi-story homes that feel anything but cramped.

Stereotype #4: “They’re Not Safe or Durable”

The Myth: Metal boxes are prone to rust and might even be toxic.

The Reality: Shipping containers are designed to withstand harsh marine environments. When properly modified, insulated, and treated, they’re incredibly durable and weather-resistant. We only use the highest-quality insulation (spray foam), apply protective coatings, and make sure NO harmful chemicals have ever been used. Our CSC Plates ensure that our containers are single-trip and never housed anything toxic. In hurricane-prone areas, container homes are stronger than traditional wood-framed houses.

Stereotype #5: “They’re Cheap and Low-End”

The Myth: Container homes are only for people who can’t afford “real” homes.

The Reality: While container builds can be affordable, many are high-end residences with custom finishes, modern appliances, and designer interiors. There are luxury container homes that cost hundreds of thousands of dollars—by choice. While many choose high end finishes and add ons that can make containers just as costly as traditional builds, there is always cost savings achieved in the shortened construction times from building off dirt with little to no construction interruptions as well as shorter lead times. There are high-rise apartments that are of the utmost quality, which are built fast for faster ROI for developers. For many, container housing isn’t about cost-cutting, but about sustainability, design innovation, and building smarter.

Stereotype #6: “You Can’t Build Them in Most Places”

The Myth: Zoning laws and building codes make container homes illegal or too difficult to build.

The Reality: While this used to be more of a problem, the rise in popularity has pushed many municipalities to adjust. More cities and counties now have clear guidelines for alternative and modular housing, including shipping container homes. In some areas, they’re even encouraged as eco-friendly or affordable housing solutions like ADUs. Like any building project, it depends on where you’re building—but red tape is no longer the brick wall it once was.

Stereotype #7: “They’re Bad for the Environment”

The Myth: Containers are made of metal and industrial materials—how can that be sustainable?

The Reality: Here’s the deal—shipping containers aren’t just sustainable because they’re reused. They're sustainable because there’s currently a massive surplus of them, especially single-trip containers from China. These containers are manufactured overseas, used once to transport goods, and then often sit idle in ports or shipping yards. Why? Because it’s cheaper to make new ones than to ship them back empty.

The good news? These lightly-used, high-quality steel containers are perfect for home building—and they’re available right now at relatively low costs. Upcoming tariffs on imported Chinese steel and manufactured goods are expected to drive up the price of steel in the near future. That makes building with surplus containers a very smart choice. You’re not only building with strong, nearly-new materials—you’re also reducing industrial waste and carbon emissions in the process.
