Our Advantage

  • Speed

    Our factory-built homes are delivered three times faster than traditional stick-built methods. Producing over 2,000 sqft of living space per day, our factory partner based in Tijuana, MX is capable of delivering housing units in the blink of an eye. Pre-Approved Modular Solutions streamline the permitting and inspection timelines.

  • Predictability

    Our systematic approach guarantees predictable outcomes, accurate timelines, and dependable results. The factory construction process eliminates the unpredictability of weather conditions, labor shortages, and unreliable contractors, ensuring your project stays on track.

  • Quality

    The strength of 100% steel framing, the energy efficiency of Title 24 certification, and the assurance of CA HCD certification combine to form the three pillars of our quality control program. Partnerships with Intertek and ICC Evaluation Services (ICC-ES) ensure our R&D, raw materials sourcing, components suppliers, manufacturing, and transportation processes are worthy of your confidence.

  • Simplicity

    The Los Arcos Development "white glove" approach ensures we tackle every step in the process for you. Hiring our team means your project is managed from site prep and unit construction to permits and final connections.
