Cost to Build a Container Home
Container homes are a popular choice for those looking to build an affordable and unique living space. The cost of a shipping container home varies, with single-container homes ranging from $25,000 to $80,000 and multi-container homes from $80,000 to $250,000 or more. The average construction cost lies between $150 to $350 per square foot, depending on size and additional features.
Here’s a breakdown of container home costs based on size and number of containers:
| Size | Square Feet | Containers | Average Cost |
|---|---|---|---|
| Home Office | 80 – 100 | 1 | $10,000 – $20,000 |
| Studio | 160 | 1 | $15,000 – $25,000 |
| 1 Bed, 1 Bath | 320 | 1 – 2 | $25,000 – $82,000 |
| 2 Bed, 1 Bath | 640 | 2 – 3 | $80,000 – $130,000 |
| 2 Bed, 2 Bath | 960 | 3 – 4 | $100,000 – $180,000 |
| 3 Bed, 2 Bath | 1280 | 4 | $150,000 – $220,000+ |

Shipping containers typically measure 8′ wide by 8.5′ high and are available in three standard lengths: 10′, 20′, and 40′. Container costs alone range from $1,200 to $10,000.
When comparing container homes to traditional homes, the latter usually costs $178,000 to $416,000 on average to build. To get an estimate for a specific container home project, consult with local shipping container home builders.
Custom vs. Prefab Shipping Container Home Prices
When comparing custom and prefab shipping container homes, there are notable differences in their costs and design possibilities. A prefab container home typically costs $120 to $300 per square foot, whereas a custom-designed container house ranges from $250 to $400+ per square foot. The total cost varies based on factors such as the home’s size, features, number of shipping containers, and number of stories.
Prefab container homes offer a more affordable option, with costs between $150 and $300 per square foot. These homes come with a finished interior and exterior, including fixtures and appliances, and are made at a factory. They require assembly on-site, particularly for homes constructed from multiple containers. Despite their affordability, prefab homes have limited customization options. However, high-end models can feature luxury finishes.
On the other hand, custom container homes cost $250 to $400+ per square foot. They provide a unique design from an architect or a design/build firm, with flexible size and layout options. The interior finishing options are limited only by the homeowner’s budget. Custom homes allow for more two-story configurations compared to prefab homes, which are predominantly single-story.
Moreover, custom container homes can cater to various functions, such as additional living areas, home offices, or eco-friendly studios. Many builders offer single-container structures suitable for use as a separate home office, guest house, in-law suite, or rental unit, placed on the same property as an existing traditional home. In most states, these single-container residential units qualify as accessory dwelling units (ADUs) when placed on an existing property.

Container Home Building FAQs
What Are Container Homes?
Container homes are residences constructed using one or more shipping containers as the primary structure. These heavy-duty steel containers are durable and weather-resistant, having been designed for cargo transport. Although container homes are a type of modular home, they differ from manufactured homes in that they follow traditional building codes rather than the U.S. Department of Housing Development (HUD) code.
Is a Shipping Container Home a Worthwhile Investment?
Shipping container homes offer an affordable and eco-friendly alternative to conventional houses. Their versatile design allows stacking or placing containers side by side, and their durability and corrosion resistance provide long-lasting structures. However, be aware that the metal exterior conducts heat and cold, requiring additional insulation. Extra care must also be taken when purchasing used containers to ensure structural integrity and avoid toxic chemical residues.
Legalities of Shipping Container Homes in Different States
Most states permit shipping container homes built on permanent foundations. However, regulations and zoning restrictions for these homes vary across cities and states, with stricter rules generally applying to tiny container homes. It is crucial to research your local zoning laws and building codes before investing in a container home.
Container Home Building Duration
On average, it takes anywhere from 3 to 6 months to build a container home, depending on its size, style, and features. Prefabricated shipping container homes typically have shorter construction times compared to custom-designed units.
Shipping Container Home Lifespan
With proper maintenance, inspections, and painting, shipping container homes can last from 25 to 30 years without requiring significant repairs. The lifespan varies depending on the local climate and weather conditions.
Value Appreciation of Shipping Container Homes
Well-maintained shipping container homes usually retain or appreciate in value. Single-container homes that are not permanently attached to a foundation are often simpler to resell since they can easily be transported to new locations.
Safety of Container Homes
Shipping container homes can be as safe as traditional houses during extreme weather, tornadoes, and earthquakes due to their wind-resistant nature. However, used containers may have previously transported harmful chemicals or pesticides, so it is essential to test them for contaminants before purchase.
Financing and Mortgaging Container Homes
Financing a container home depends on whether it adheres to local building codes and zoning regulations, its size, features, and location. Larger, multi-container homes typically qualify for standard mortgages, whereas tiny container homes may require alternative financing options such as builder loans, mobile home loans, or unsecured personal bank loans. Some lenders may categorize container homes of all sizes as mobile homes, limiting mortgage possibilities. Homes built as accessory dwelling units (ADUs) on shared properties could potentially be eligible for mortgage financing through Freddie Mac.
