BEST Shipping Container To Buy for Your Container Home

Check Local Rules and Building Laws

Before you say yes to a container house, make sure you know the local rules. You need to check what is allowed in your area. If you do not check this, you may run into big trouble and costs you did not expect later.

No state in the US says “no” to container houses for good, but the real problems often come from the city or county rules.

Look at Local Land Laws

Land rules say where you can build things like a home from a container. Go to your city or county web page to read the rules for building a house. You can also look up “shipping container rules” and write your city and state name. Check the city’s land maps to see if your land is meant for homes, shops, or work places.

Big towns often have more and harder rules you need to follow to build new things. In the country, the rules are often not so tough. When you talk to the people who make land rules, ask about these things:

• If you need a permit to live in your container home
• If you can use the house for storage
• If your container house is seen as a short term or long term home
• The least lot size you must have
• How far your house must be from the street and sides

It helps to ask if anyone near you built a container home that got approved. If others have done it, it may be faster and easier for you to get approval too.

If your land is in a planned group or community, check if there are special rules from the home group, called the HOA. These groups can sometimes say “no” to new or odd types of homes, like a container home.

Once you know you can build, the next thing is to check what you need for your building permit.

Know What You Need to Get a Permit

You need both land rule approval and a building permit. Most areas use rules from a book called the International Residential Code (IRC) for homes, or sometimes the International Building Code (IBC) for big buildings, but your local office may change some rules. The 2021 IBC also has new rules for container homes under Section 3115. This may help you get your house approved more easily as more places use these rules.

"All manufactured homes are built to the Manufactured Home Construction and Safety Standards, 24 CFR Part 3280... Shipping containers that are converted into housing units are subject to state and local building codes like modular and site-built homes."
– U.S. Department of Housing and Urban Development (HUD)

The permit steps will look at key safety parts, like walls that keep heat in, water pipes, wires for power, and ways to keep a space warm or cool. Still, if you only use the box for keeping things, you may not need as many papers or steps.

Start your permit plans soon, since waiting for a “yes” may take just a few days or even many weeks. Always ask for proof in writing of what you can do - like an email or a letter - so you stay safe if the rules change. If you send plans that a skilled builder has signed, it can help move things along more fast with your city or town.

"Though it may seem like there shouldn't be any restrictive laws if you want to live in a container, there are often several unsuspecting hoops you have to jump through to build a tiny home."
– Yavuz Yavuzer, outdoor renovation expert, FibroPool

To have an easy time, work with builders or teams who know how to make homes out of big steel boxes. These people know the rules in your town. They have worked with folks at the office that checks houses. This helps you go fast and keeps your work simple.

Choose the Right Container

Once you've got your permits and local rules sorted out, the next step is picking the right shipping container for your project. This decision is a big one, as it directly impacts your budget, space, and overall design options. Shipping containers typically come in two main sizes: 20-foot units and 40-foot units, both standardized at 8 feet wide. The 40-foot container gives you more room to play with design-wise, but keep in mind it usually comes with higher transportation and modification costs. These factors will shape not just your layout but also your overall expenses.

Most standard containers are about 8 feet wide and 8.5 feet tall on the inside. If you're looking for a bit more height, consider a high cube container. These give you an extra foot of headroom, bringing the interior height to nearly 9.5 feet. This extra space can be a game-changer if you're planning to add insulation or interior walls. Weigh these specifications carefully against your budget and customization needs.

New vs. Used Containers

When it comes to condition, you've got a few options. New containers are straight from the supplier and have no wear or damage, giving you a clean slate. However, they can be pricey. A popular alternative is one-trip containers - these have only been used for a single shipping voyage. They’re usually in excellent shape and come at a slightly lower price than brand-new units.

For those on a tighter budget, used containers can be a good choice, but they require a bit more scrutiny. Some used units may only need a quick cleaning or minor fixes, while others might come with hidden issues that could drive up renovation costs. Look for wind and watertight (WWT) containers, which are generally in solid condition. Cargo-worthy containers are another reliable option, as they meet shipping standards. Be cautious with containers sold "as-is" unless you can inspect them firsthand - these often come with risks that might not be worth the savings.

Inspect Container Condition

Before you commit to buying, give the container a thorough inspection. Start with the exterior - check for rust, dents, or any holes or cracks. While surface rust is fairly common, deep rust that eats through the metal is a red flag.

Inside, pay close attention to the flooring. Look for soft spots, stains, or any strange odors, which could point to water damage or past exposure to chemicals. Press gently on different areas of the floor to test for weak spots.

Make sure the door seals and hinges are in good working order, and inspect the structural posts for any damage. These posts, along with the corner supports, are crucial for the container’s strength, especially if you plan to stack units or make major modifications. Cracks, heavy dents, or significant rust in these areas could compromise safety.

Don’t forget to check the ceiling. Signs like water stains, rust, or sagging could indicate roof problems that might worsen once you add insulation or other interior work. It’s also smart to ask about the container’s cargo history - units that carried food products are usually cleaner, while those used for chemicals or hazardous materials might carry lingering risks, even after cleaning.

Lastly, be wary of deals that seem too good to be true. Some sellers might try to cover up defects by painting over rust or damage. Simple tests, like using a magnet to detect inconsistencies, can help you spot hidden issues. And don’t overlook delivery costs - they can vary a lot depending on how far the container needs to travel and how accessible your site is.

Plan Your Budget and Modifications

Planning your budget carefully is crucial to avoid unexpected expenses. Many buyers focus solely on the container's price and overlook the additional costs tied to converting it into a livable or functional space. Accurate cost estimates will help you stay on track throughout the entire process.

Estimate Total Project Costs

When budgeting, remember that the container's price is just the starting point. Expenses like insulation, plumbing, and electrical work can significantly add to the total cost. Even seemingly simple changes, like cutting openings for doors or windows, can weaken the container's structural integrity. This often requires extra steel reinforcement, which can drive up costs even further.

Budget for Customizations and Upgrades

Customizing your container can also increase expenses. For example, insulation, plumbing, and electrical systems should not only meet your design goals but also fit within your budget. If your project involves connecting multiple containers, additional welding and reinforcement will be required to ensure they are structurally sound. Lastly, finishing touches like interior and exterior treatments can sometimes make container homes as costly as traditional stick-built houses. This makes thorough planning and budgeting an absolute must to avoid financial strain.

Prepare the Land and Utilities

Getting your site ready with the proper foundation and utility connections is a crucial step. The type of foundation and utility setup you choose will directly influence your container home's stability and functionality. In most states, residential container homes are required to have a permanent foundation, and this is often a preference for banks when it comes to financing. Be sure to select a foundation suited to your site conditions and construction plans.

Choose Your Foundation

Your foundation choice hinges on several factors: site conditions, local regulations, budget, and the overall design of your home. Before installing the foundation, the soil must be leveled. It's important to research local zoning laws and building codes early in the process since foundation requirements can vary significantly by county and city.

Foundation Type	Best For	Key Benefits	Considerations
Pier Foundation	Tiny container homes, budget-friendly projects	Affordable and quick to build with concrete blocks or piers	May not comply with all local codes
Pile Foundation	Flood-prone areas, unstable soil	Steel tubes driven into the ground provide stability	Higher cost; needs specialized tools
Slab Foundation	Permanent residential homes	Durable and solid concrete base; offers long-term value	Higher material costs; longer to install
Strip Foundation	Medium-term installations	Concrete strips around the perimeter offer solid support	Moderate cost and durability

Once your foundation is in place, it’s time to connect the utilities, ensuring they align with your design and meet local requirements.

Set Up Utility Connections

Utility connections should be planned carefully, with input from certified professionals, and must adhere to local codes. This includes your electrical, plumbing, and sewage systems, all of which must meet specific safety and functionality standards.

Electrical systems need to comply with the National Electrical Code (NEC), which sets guidelines for wiring, outlets, and circuit breakers. Similarly, plumbing systems must align with local codes, covering everything from pipe materials to sanitation and water flow standards. Plan these layouts before you begin any interior work.

"Electrical and plumbing systems in container homes must follow local codes to ensure safety and functionality. The National Electrical Code (NEC) outlines requirements for electrical installations, including wiring, outlets, and circuit breakers. Local plumbing codes cover pipe materials, sanitation, and water flow standards. Inspections by certified professionals confirm adherence to these codes, reducing the risk of future issues."

Always work with licensed professionals for these installations. Make sure to secure all necessary permits from your local building department, including those for building, electrical, plumbing, and occupancy. Schedule inspections to ensure compliance with local regulations and International Building Code (IBC) standards.

Hire Professionals for Modifications

When you're ready to move forward with your container home project, hiring the right professionals is essential. Modifying a shipping container isn’t as simple as it might seem - tasks like cutting openings or combining units require expertise to ensure safety and structural stability. Here’s how to find skilled contractors who can turn your container into a functional, comfortable living space.

Find Qualified Contractors

Start by looking for contractors who have hands-on experience with container home projects. Ask for specific examples of their past work, especially projects involving container modifications. This will give you a clearer picture of their expertise and whether they specialize in this type of construction. Don’t hesitate to request references to confirm their claims and the quality of their work.

Make sure the contractor is well-versed in container-specific challenges, such as safely combining units without compromising their structure. Ask how they handle critical aspects like insulation, waterproofing, and energy efficiency, especially in relation to your local climate. These details can make or break the comfort and longevity of your container home.

It’s also important to verify that the professionals you hire are properly certified and licensed. For specialized tasks like electrical work and plumbing, ensure the team includes experts with the necessary credentials. Additionally, ask about their approach to managing timelines, staying within budget, and addressing unexpected challenges.

Once you’ve confirmed their technical skills, check their understanding of local building regulations.

Meet Code Requirements

Your contractor should have a solid grasp of local zoning laws and building codes, including standards like the International Residential Code and the National Electrical Code. They should also be familiar with the permitting process specific to container homes in your area. Confirm that they can navigate these requirements to ensure your project complies with all regulations.

Complete Your Container Home

After laying the groundwork with a solid foundation, utility installations, and contractor modifications, it’s time to wrap up your container home project. These final touches ensure your home is ready for living and meets all necessary safety and compliance standards.

Install Interior and Exterior Finishes

Start by focusing on insulation to maintain a comfortable indoor climate and prevent condensation. Proper insulation is key to making your container home livable. For flooring, pick materials that balance durability with design - something that looks great and holds up over time. When it comes to interior walls, options like drywall or other wall coverings can give your home a clean, polished appearance.

On the outside, weatherproofing is just as crucial. Use a high-quality primer and paint specifically made for metal to shield your container from harsh weather conditions. Don’t forget to plan for compact, efficient kitchen and bathroom fixtures to maximize your space.

Get Final Inspections

Once all installations are complete, schedule a final inspection with your local building department. This step ensures your home complies with safety standards and local codes. Electrical work should be handled by a licensed professional, and plumbing connections need to meet all regulations. For the HVAC system, make sure it’s installed with the unique properties of a metal structure in mind.

Before the inspection, test all systems - water, electrical, and HVAC - to catch any issues early. Being thorough can save you time and money by avoiding re-inspection fees or delays. Once you pass the inspection and receive your certificate of occupancy, your container home is officially ready for move-in. It’s now a functional, minimalist space you can call home.

FAQs

What challenges do people face when getting permits for container homes, and how can they address them?

Getting permits for container homes can be tricky because of local zoning laws, strict building codes, and regulations that vary by location. Since container homes are often seen as unconventional, some municipalities may hesitate to approve them.

To navigate this, start by digging into your area’s zoning rules to see if container homes are even allowed. Then, take time to understand the building codes to make sure your design is up to safety and structural standards. It’s also smart to connect with local officials or bring in a professional who knows the ins and outs of container home regulations. These steps can save you time and help make sure your project stays on the right side of the law.

What should I consider when choosing between a new, one-trip, or used shipping container for my home?

When deciding whether to go with a new, one-trip, or used shipping container, it all comes down to your budget, project goals, and the condition you’re looking for. Here’s a quick rundown of the options:

• New (One-Trip): These containers are practically brand new, having only been used once to transport goods from the manufacturer. They’re in top-notch condition, with minimal wear, making them ideal if you want something extremely durable and with a clean, pristine look. Keep in mind, though, they come with the highest price tag.
• Used: If you’re looking to save money, used containers are the way to go. While they’re more affordable, they often show signs of use - like rust, dents, or scratches. That said, many of them remain structurally sound and can work well for projects like home construction. They’re a solid option if you’re okay with putting in some effort for repairs or modifications.

Ultimately, think about what matters most to you - whether it’s cost, appearance, or how much work you’re willing to do - to figure out which container suits your needs best.

How can I make sure my container home complies with local building codes and regulations?

To make sure your container home meets local building codes and regulations, the first step is to look into the zoning laws in your area to verify whether container homes are allowed. Once confirmed, you'll need to secure all the required permits, such as those for building, electrical, and plumbing work, based on your local government's requirements.

Partnering with a licensed contractor or engineer is crucial to ensure your home complies with safety standards and passes inspections. This involves checking for structural stability, proper insulation, and compliance with fire safety rules. Taking care of these details early on can help you avoid delays, extra costs, or legal complications later.
