Standing in the front of sustainable, unconventional home architectural trends, the shipping container barndominium shows how container-based homes lead the way.
The barndominium promises affordability, sustainability, and a unique look. However, as with any unconventional build, container barndominiums come with their challenges.
If you’re considering this housing option, it’s important to know the most common problems and, more importantly, how to fix them.

Common Problems and Fixes for a Shipping Container Barndominium
Here’s a comprehensive look at the real-world issues you might face, backed by legitimate sources, and practical solutions for each.
Permitting and Zoning Headaches
One of the first hurdles for any shipping container barndominium is navigating the maze of local permitting and zoning laws.
Why? It’s because municipalities don’t have clear guidelines for container-based homes, leading to confusion and delays.
Even worse, some areas may outright prohibit their use, while others require extensive paperwork and inspections.
So, what can you do?
- Do your homework early: Research local zoning and building codes before you buy land or containers.
- Talk to your local building department: Ask about specific requirements for container homes.
- Hire a pro: Consider working with an architect or builder experienced in container construction to help with permits and inspections.
Luckily, some states like Texas, Louisiana, and Oregon are more container-home-friendly than others, so you might want to move there.
Furthermore, look for communities where alternative housing is welcomed or where other container homes have already been approved.
Space Limitations and Layout Challenges
Shipping containers are, by nature, long and narrow-typically 8 feet wide and 20 or 40 feet long. This can make interiors feel cramped and limit design flexibility.
Adding more containers increases complexity and cost, especially if you want open-concept living spaces.
Fix:
- Stack or join multiple containers: Create larger, open spaces by combining containers side-by-side or end-to-end.
- Plan your layout carefully: Use open floor plans and large windows to make spaces feel bigger.
- Go vertical: Consider high-cube containers for extra headroom, or add a second story if your site and budget allow.
Tip: Use sliding doors and multi-purpose furniture to maximize usable space. Think vertically- lofts and mezzanines can add living or storage areas without expanding the footprint.
Structural Integrity After Modifications
Cutting into containers for windows, doors, or open-concept spaces weakens their original structure.
Without reinforcement, this can lead to sagging, leaks, or even collapse.
Fix:
- Reinforce openings: Always weld additional steel around any major cuts.
- Work with professionals: Structural engineers or experienced container builders can ensure your modifications are safe and code-compliant.
- Inspect regularly: Look for signs of stress or movement, especially around large openings.
Insulation, Condensation, and Temperature Control
Containers are made of steel, which is a poor insulator and prone to condensation.
Without proper insulation, interiors can become unbearably hot in summer, freezing in winter, and damp year-round.
Fix:
- Use high-quality insulation: Spray foam is a top choice because it seals gaps, blocks moisture, and has a high R-value. Rigid foam panels and mineral wool are also good options.
- Install vapor barriers: These prevent moisture from getting trapped inside the walls.
- Ventilate: Use mechanical ventilation or dehumidifiers to keep air moving and control humidity.
- Seal all gaps: Pay special attention to corners, seams, and around windows and doors.
If you need some advice from us, don’t skimp on insulation-energy savings and comfort are worth the upfront investment.
Corrosion and Rust
Even though shipping containers are made from weathering steel (Cor-ten), they’re not immune to rust-especially in humid, coastal, or rainy environments.
Rust can weaken the structure and lead to leaks.
Fix:
- Elevate your container: Use a proper foundation (piers, slab, or gravel pad) to keep the container off wet ground.
- Apply rust-resistant paint or sealant: Regularly inspect and touch up any scratches or exposed metal.
- Install gutters and drainage: Prevent water from pooling on the roof or around the base.
- Repair damage quickly: Sand and repaint any rust spots; replace corroded panels if needed.
Condensation, Mold, and Air Quality
Metal walls can “sweat,” especially when there’s a big temperature difference between inside and outside.
If the sweating occurs for far too long, it leads to condensation, which can cause mold, mildew, and poor air quality.
Fix:
- Insulate thoroughly: As above, spray foam is excellent for preventing condensation.
- Use vapor barriers: These stop moisture from reaching cold steel surfaces.
- Ventilate: Install exhaust fans in kitchens and bathrooms, and consider a whole-house ventilation system.
- Monitor humidity: Use a hygrometer and run a dehumidifier if needed.
Health and Safety Concerns
Some shipping containers are treated with pesticides or have floors containing hazardous chemicals.
Paints may contain lead or other toxins, posing a risk to your health if not properly addressed.
Fix:
- Source containers carefully: Buy from reputable suppliers and ask for documentation on previous use.
- Remove or seal original floors: Replace with new, non-toxic flooring or seal with epoxy.
- Strip and repaint interiors: Use non-toxic, residential-grade paints and coatings.
- Test for lead and other toxins: If in doubt, hire a professional for testing and remediation.
To prevent this problem from happening, always request a “one-trip” or new container for residential builds to minimize these risks.
Floor Damage and Maintenance
Container floors are often made from plywood, which can rot or become damaged from heavy use, moisture, or pests.
Fix:
- Inspect floors before purchase: Look for signs of rot, warping, or pest damage.
- Replace or reinforce: Install new marine-grade plywood or another durable flooring material.
- Seal floors: Use a waterproof sealant to protect against spills and moisture.
Tip: Consider installing a subfloor and finished flooring (like tile or laminate) for comfort and durability.
Dents, Scratches, and Holes
Shipping containers can arrive with dents, scratches, or even holes from their previous life at sea. These imperfections can lead to leaks, rust, or structural weakness.
Fix:
- Repair dents: Small dents can be hammered out; larger ones may need welding.
- Sand and repaint: Address scratches quickly to prevent rust.
- Patch holes: Weld steel patches over any holes and repaint for weatherproofing.
recommends annual inspections and touch-ups to keep your barndominium in top shape.
Building Codes and Inspections
Many regions lack clear building codes for shipping container homes, leading to confusion and extra scrutiny from inspectors. This can cause delays and unexpected costs.
Fix:
- Work with local officials early: Involve them in your planning process to avoid surprises.
- Hire experienced professionals: Architects and builders familiar with container homes can help navigate code requirements.
- Document everything: Keep records of permits, inspections, and modifications.
Tip: The more proactive you are, the smoother your build will go.
Customization Limitations
The rigid, rectangular shape of shipping containers can make it tough to achieve certain design goals.
Creating large, open spaces or complex layouts often requires more containers and structural work, which increases costs and complexity.
Fix:
- Embrace modular design: Use the container’s shape to your advantage, or combine multiple units for larger spaces.
- Plan carefully: Work with a designer who understands container architecture.
- Prioritize your must-haves: Focus on the features that matter most and be flexible with the rest.
Tip: Look for inspiration from real-life container homes. Many creative solutions exist for maximizing space and style.
Foundation and Site Prep
A poor foundation can lead to settling, moisture problems, and structural issues. Site prep is often underestimated in terms of cost and importance.
Fix:
- Choose the right foundation: Options include pier, slab, or gravel pad with pros and cons.
- Prepare the site: Clear and level the ground, address drainage, and ensure easy access for delivery.
- Consult a pro: A structural engineer or experienced contractor can recommend the best foundation for your site.
As such, now we see how foundation work is one of the most important investments for a long-lasting barndominium.
Ongoing Maintenance
Like any home, a container barndominium requires regular upkeep. Neglecting maintenance can lead to rust, leaks, and other costly problems.
Fix:
- Inspect regularly: Check for rust, leaks, and damage, especially after storms.
- Clean and repaint: Keep the exterior clean and repaint as needed to protect against the elements.
- Maintain seals and insulation: Replace worn seals and check insulation for moisture or pests.
Tip: Schedule annual checkups and address issues promptly to avoid bigger repairs later.
