How We Deliver Premium Quality at This Price

Factory Precision

Built in a controlled factory environment — no weather delays, no material waste, and assembly-line precision that reduces costs without reducing quality.

Steel-Frame Innovation

Commercial-grade steel framing is stronger, lighter, and more efficient than traditional wood. It is also fire-resistant and termite-proof — built to last.

All-Electric Design

100% electric means no gas lines to run, no gas meter to install. Simpler utility connections mean lower site costs and a cleaner, more efficient home.

Frequently Asked Questions

Can you really get a premium prefab ADU for under $150,000?

Yes. EVO ADU offers two factory-built models under $150,000: the EVO Compact at $135,800 (350 sq ft) and the EVO Studio at $147,920 (450 sq ft). Both include commercial-grade steel framing, full kitchen, complete bathroom, and all premium finishes. Foundation, permits, and site work are additional costs that vary by property.

Why does EVO ADU cost less than other premium builders?

EVO ADU does not cut quality to lower the price. Instead, factory manufacturing eliminates weather delays and material waste. Steel framing is lighter and faster to assemble than wood. All-electric design removes gas infrastructure costs. These efficiencies add up — allowing EVO ADU to deliver a genuinely premium product at a more reasonable price.

What is included in the $135,800 price?

The EVO Compact at $135,800 includes the complete factory-built unit: commercial-grade steel frame, full kitchen with appliances, complete bathroom, flooring, lighting, electrical, plumbing, insulation, and all interior and exterior finishes. Foundation, permits, utility connections, and site preparation are additional and vary by location.

What additional costs should I expect beyond the unit price?

Beyond the unit price, you will typically need to budget for foundation work, permit fees, utility connections (electrical, water, sewer), site preparation, and delivery/crane costs. These vary significantly by city and property conditions. EVO ADU provides a complete cost estimate during your site assessment.

Can I use an EVO ADU as a rental?

Absolutely. Both the EVO Compact (350 sq ft) and EVO Studio (450 sq ft) are excellent rental units. California ADU rental income typically ranges from $1,500 to $3,500 per month depending on location. With premium finishes and steel-frame durability, EVO ADUs are built to perform as long-term rental investments.
