Barndominium Builders questions, answered by experts

It is a good idea to check in with your local city and state regulations before committing to building a shipping container home no matter where you live. This concept is pretty new across the country, and many places won’t let you build one.

The International Code Council (ICC) offers guidelines for home builders on the safe use of ISO intermodal shipping containers repurposed as building components, which can be helpful to review when planning or designing a shipping container home.

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior.
