Compared to similar-size models from leading competitors
EVO ADU is the only major prefab ADU builder in California using commercial-grade steel framing. This means superior fire resistance, termite protection, and structural durability — at a price point that starts well below the competition. Other factory-built competitors use wood framing and start at $199,900 or more.
EVO ADU achieves better pricing through efficient factory manufacturing, steel-frame construction that is lighter and faster to assemble, and 100% electric design that eliminates gas infrastructure. The result is a premium product at a more reasonable price — not a cheaper product, but a smarter one.
Steel-frame ADUs offer several advantages: they are naturally fire-resistant (critical in California), termite-proof, and dimensionally stable with no warping or shrinking. Steel framing also allows for longer spans and more open floor plans. EVO ADU is the only major prefab ADU builder in California using commercial-grade steel framing.
Consider construction quality, materials, pricing transparency, and what is included. EVO ADU uses steel framing (stronger and fire-resistant), starts at $135,800, and includes premium finishes. Many competitors use wood framing and start significantly higher. Always compare what is included in the base price — not just the headline number.
Yes — prefab ADUs typically cost 20–40% less than site-built construction, are completed faster, and offer consistent quality from factory manufacturing.
