Modular Home in NJ Building Process

High-Quality Homes

Our manufacturing plant's state-of-the-art facility allows us to construct consistently high-quality prefab homes, and we ensure that all of these undergo uniform construction processes and stringent inspections. Each of our manufacturers here at Coastal Modular Group have been trained to do their task efficiently, and their experience has made them an expert on a particular aspect of home construction.

To assure our clients that their homes will meet, or even exceed, all state building codes, all of our homes are inspected by a third-party home inspection agency before it leaves the factory. Our homes are again inspected by a local building inspector once it is erected on-site to ensure that your home meets the quality and structural integrity requirements.

Flexible Designs

Limitless design possibilities await you when you work with Coastal Modular Group for your prefab home. Our designs tend to be less per square foot compared to site-built homes, allowing you to add more rooms for an affordable price.

Not only can we create custom designs through computer-aided software, but we can also send these designs to the machinery in our manufacturing facility. This way, your customizations will translate to the finished product as precisely as possible.


Design Modular Homes in NJ

Energy Efficient and Eco-Friendly

Unlike site-built custom homes, we build prefab homes from the inside out. With this, we can then fill gaps around pipes, outlets, doors, windows, and exterior sheathing. This then translates to advanced energy efficiency and lower energy costs.

In a way, you're doing Mother Nature a big favor in opting for our prefab homes. Our eco-certified green modular homes use only ENERGY STAR programs and products in our prefab homes, giving you big savings in energy costs and even qualifying you for green building rebates and mortgages.
