Build in 3 Steps.

Traditional stick building can be slow, expensive, and frustrating. With our purpose-built, Pre-Approved Modular Solutions, You Will be able to build 3 times faster in just 3 steps.

Step 1: Site Prep

Los Arcos Development will manage the entire process of preparing your land to receive the ADU unit. From grading to foundation setting, our team aims to complete this process in 2-3 weeks.

Step 2: Unit Installation

Once your site is prepared, we coordinate the delivery and “drop” of your unit. Your ADU can arrive next day 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.
