Traditional construction always carries the risk of delays, rising costs, and unpredictable timelines. Modular buildings are constructed off-site in a controlled factory environment, which allows for faster construction times. This is because modules can be built simultaneously while site preparation is underway. Modular buildings can be completed up to 50% faster than traditional buildings. At California Modulars, we let you enjoy the benefits of modular commercial buildings while keeping the costs low.
Modular buildings are constructed to the same building codes and standards as traditional buildings. However, the factory-controlled environment allows for greater quality control and consistency.
Modular buildings can be more cost-effective than traditional buildings, especially for large and complex projects. Modular construction is not directly subject to prevailing wage and project labor agreements since most work is completed in-factory.
Fabrication in a factory environment is more efficient and less wasteful resulting in a more sustainable construction project rather than traditional site-built construction.
Modular buildings are typically transported to the construction site and assembled on-site, which minimizes disruption to the surrounding areas.
Modular construction is generally safer than traditional construction because it takes place in a controlled factory environment.
Modular construction projects are typically more predictable than traditional construction projects because the factory-controlled environment allows for greater control over the construction process.

We are committed to utilizing sustainable, eco-friendly materials and construction methods, advocating for the right of everyone to enjoy a healthier, higher quality living space. Our modular structures adhere rigorously to California Title 24 and CalGreen guidelines to fulfill this commitment. Our modular commercial buildings help reduce waste and can easily be repurposed or relocated to a new location, reducing the impact on the environment. We turn your buildings into long‑term assets and help your organization lower its environmental footprint.

Our process begins with a scheduled phone conversation with our team. We discuss your goals and vision for the home, the site, your budget, and timelines.
(30-45 minutes)
The next step will be to evaluate your site and get a clear understanding of the unique qualities of your property to include general access, utility locations and overall site development needs.
(1-2 hours)
Following our site evaluation, we will execute a pre-construction agreement with you that includes a complete set of architectural drawings, HCD approved construction documents and submittal to the local building department for approval.
(2-6 weeks)
Our design and engineering team will work with the local agencies to obtain all of the necessary permits and approvals to fully complete your project. Once received, we are ready to move on to construction and fabrication.
(4-8 weeks)
A dedicated project manager will oversee the factory construction and site development so all aspects of the project flow seamlessly. Fabrication and site work will take place concurrently, saving significant time and money.
(8-16 weeks)
Upon completion of all manufacturing and site improvements, your home/ADU will be delivered by truck and set by crane or other means, directly onto the foundation.
