Container Homes FAQ

Relevant Buildings is a licensed container home builder and modular modular manufacturer based in Oregon, USA. We specialize in engineering prefabricated shipping container homes and accessory dwelling units (ADUs) crafted from upcycled industrial Corten steel containers.

All our homes meet the International Building Code (IBC) and Energy Trust efficiency benchmarks. We deliver fully completed turnkey buildings regionally, as well as structural export shells for international housing projects.

Yes. Our modular buildings are designed and engineered to meet identical building codes as traditional site-built structures. Each factory-completed home carries official State Insignia certification tags for prefabricated structures.

This official compliance allows our buildings to be legally sited for primary single-family residences, multi-family developments, backyard ADUs, commercial units, or hospitality resorts with complete support for conventional bank financing and insurance coverage.

We primarily utilize standard 20-foot and 40-foot High-Cube ISO shipping containers. High-Cube units provide an upgraded exterior height of 9'-6" (2.9m), allowing ample space for ceiling insulation, interior drywall, and high indoor ceiling clearances.

Available models span from compact 318 sq ft studio suites to expanded 1,148 sq ft multi-container homes incorporating separate bedrooms, bathrooms, and modern living quarters.

Yes. For clients located outside our turnkey service zones or overseas procurement partners, we offer structural "Shell" packages. A container shell includes complete structural steel cutting, reinforced metal framing, exterior door/window installations, marine-grade exterior coating, and full engineering documentation.

Export shells allow developers and self-builders to transport structural modules efficiently and complete interior mechanical, electrical, and finishing work locally.

Protection against moisture and rust is integrated into our structural engineering. We apply continuous closed-cell spray foam insulation directly onto interior corrugated steel surfaces, establishing a vapor-impermeable barrier that prevents condensation formation.

Exterior steel surfaces are shielded with multi-coat marine protective paint systems. Furthermore, balanced ventilation is maintained inside every home through Energy Recovery Ventilators (ERVs) to regulate indoor air quality and humidity.

Our homes feature closed-cell foam insulation delivering high thermal resistance per inch, exceeding standard building thermal code requirements by at least 10%. Heating and cooling are powered by ductless mini-split heat pump systems, offering exceptional energy efficiency and localized temperature control.

Yes. The heavy-duty Corten steel roof frame supports solar PV panel arrays cleanly. We can pre-wire electrical conduits to streamline future photovoltaic panel and battery backup installations for off-grid or net-zero applications.

Factory production inside our controlled manufacturing facility requires approximately 3 months. Overall timeline dependencies rely heavily on site permitting, foundation preparation, and local utility installation schedules.
