Once we've established the basics, our design team works with you to customize your container home. We offer pre-designed floor plans that can be modified or the option to create a completely custom layout.

3. Permitting and Compliance

Navigating local building codes and permit requirements can be challenging. Our team handles this complex process for you. We prepare and submit all necessary documentation to local authorities. We stay current with ADU-specific regulations, which often differ from standard building codes.

Before your container ADU arrives, we thoroughly prepare your site. Our team conducts detailed surveys to determine the optimal placement and foundation requirements for your specific property.

5. Container Modification

We transform shipping containers into comfortable living spaces through strategic modifications. Our process begins in our off-site facility where containers undergo thorough cleaning, structural reinforcement, and rust prevention treatments.

FAQs on Shipping Container ADU Builds


Hi there! Have some questions about our service? Find the answers below. 

What are the different design options available for shipping container homes?

Shipping container homes offer diverse design possibilities ranging from simple single-container studios to complex multi-container estates. Common approaches include stacking containers for multi-story structures, arranging them in L or U shapes for courtyards, or cantilevering them for architectural interest. 


Many designs incorporate large cutouts for windows, sliding glass doors, or open-concept living spaces that transform the industrial box into a comfortable home. Exterior options range from preserving the container's industrial aesthetic to completely disguising it with cladding, siding, green walls, or decorative screens. Container homes can also integrate sustainable features like green roofs, solar panels, rainwater collection systems, and passive heating/cooling designs.

How much does it typically cost to build a container home?

Describe the item or answer the question so that site visitors who are interested get more information. You can emphasize this text with bullets, italics or bold, and add links.

What is the typical timeline for constructing a shipping container ADU?

The typical timeline for completing a shipping container ADU ranges from 2-6 months from concept to move-in. Planning and permitting generally take 1-2 months, depending on local jurisdiction requirements and review processes. 


The container modification phase, which includes cutting openings, structural reinforcement, and initial utility preparation, typically requires 3-6 weeks. On-site installation, including foundation work, container placement, and utility connections, usually takes 2-4 weeks. Interior finishing work, including insulation, drywall, flooring, and fixtures, represents the final major phase, generally requiring another 3-6 weeks before final inspections.

Can shipping container homes be customized to meet specific living needs?

Shipping container homes offer exceptional customization potential for addressing specific living requirements and personal preferences. The modular nature of containers allows for easy expansion by adding units, creating spaces tailored to family size or specialized needs like home offices or guest quarters. Interior layouts can be completely customized, with non-load-bearing areas available for open-concept designs or specialized accessibility features. 


Windows, doors, and skylights can be positioned strategically to maximize natural light or capture views, completely transforming the container's industrial character. Finishes, built-ins, smart home technology, and energy systems can all be tailored to match lifestyle needs and aesthetic preferences.

What are the zoning and building codes to consider when installing a shipping container ADU?

When installing a shipping container ADU, you'll need to research local zoning ordinances regarding accessory dwelling units, including size restrictions, setback requirements, and occupancy regulations. Most jurisdictions require building permits addressing structural modifications, foundations, insulation R-values, ventilation, ceiling heights, egress windows, and utility connections. 


Container homes must meet the same building code requirements as traditional construction, though some areas have additional requirements specifically for alternative construction methods. Special consideration should be given to foundation design, as containers require proper structural support to prevent warping or settling over time. Some neighborhoods or historic districts may have additional design review requirements or homeowner association restrictions that impact container home projects.

How does the durability and maintenance of container homes compare to traditional constructions?

Shipping containers are built from weathered-resistant Corten steel designed to withstand harsh ocean transport conditions, potentially offering excellent durability against weather extremes and resistance to pests like termites. The steel structure requires different maintenance than wood framing, particularly attention to preventing rust and condensation through proper insulation, ventilation, and protective coatings. 


Container homes typically perform well in high-wind environments and seismic conditions when properly anchored, though they require thoughtful engineering to address heat transfer issues inherent to metal construction. The industrial-grade flooring in containers often contains chemical treatments that may need replacement for healthy indoor living, while roof maintenance is crucial as standing water can accelerate deterioration. With proper construction and maintenance, container homes can last 25+ years, comparable to conventional homes, though repair approaches differ when addressing damaged steel versus traditional building materials.
