ADU 3X Faster

We exclusively use State of California HCD-certified (Housing and Community Development) Modular Buildings to ensure the absolute highest level of quality and durability. Modular Construction Homes (oftentimes called “prefab” homes) provide homeowners with a fast, cost-efficient solution to their housing needs.

How it Works

  • Step 1: Plans, Permits and Prep

    Los Arcos Development will manage the entire process of preparing your land to receive the ADU unit. From plans and permits to grading and foundation setting, our team aims to complete this process within 2-3 weeks of receiving approval to build from the city/county.

  • Step 2: Unit Installation

    Once your site is prepared, we coordinate the delivery and “drop” of your unit. Up until now your unit has been constructed in the factory, inspected, and approved by CA HCD. Your ADU can arrive the next day following site readiness and is installed via crane in just one day.

  • Step 3: Utility Connection

    The final step, we efficiently connect your unit to solar or public electrical service, plumbing, and sewage. At this point, your ADU is entirely move-in ready.
