We're passionate about innovative structural engineering solutions for all residential projects. Recently, RPM partnered with a homeowner in Sonoma County, California to create a unique living space: a duplex ADU.

The partnership played a key role from the outset. We conducted a thorough site assessment, designed the structural layout, ensuring safety, stability, and compliance with local building codes. Through creative solutions and clear communication with the homeowner, RPM Team delivered a comprehensive set of structural plans, paving the way for a successful duplex ADU project.

RPM is your trusted provider of structural engineering and turnkey ADU project management.

Optimized ADU Engineering Process: We've meticulously developed a streamlined ADU engineering process that prioritizes both efficiency and clarity. This ensures your project progresses smoothly, while maintaining open communication throughout every step.

Deep Understanding of ADU Complexities: Our team possesses a comprehensive understanding of the intricate challenges and considerations specific to ADU projects. This expertise allows us to anticipate potential roadblocks and navigate them effectively.

We understand the excitement and potential of adding an Accessory Dwelling Unit (ADU) to your property. But before you break ground, a crucial step is ensuring a safe and structurally sound structural engineering team.
