Quality & Durability standards

By fabricating off-site and employing proprietary innovations for the building envelope and mechanical systems, ZETA achieves higher quality while reducing waste and cost. We start with dry lumber and frame indoors with jigs and pre-cut material to produce structures with better dimensional control, strength and rigidity. Installing waterproofing, flashing, insulation, windows, siding, and other high performance materials off-site allows for better control, greater worker access and an efficient fabrication sequence, in turn producing a building envelope that is more reliable than conventional construction. And, most interior finishes are installed in the factory, further improving quality and reducing cost.

Precision building & Lean manufacturing

Our Bay Area fabrication facility serves the entire Northern California market. The processes employed by the dedicated factory team reflect the latest lean manufacturing techniques, assuring the highest quality construction combined with high efficiency and minimal waste. ZETA's designs leverage CAD/CAM design documentation, enabling precision building techniques at ZETA suppliers and inside the ZETA fabrication processes. ZETA's direct factory flow assures that material handling is minimized and build quality and efficiency is maximized. In addition to ZETA's quality control at every step, ZETA uses an independent inspection team to verify build quality at sub-assembly and final assembly levels. ZETA's modules are 80% completed in the factory and then shipped to the site for installation on ZETA's permanent foundation. The ZETA fabrication process includes parts and assembly tracking for every module so that field performance and reliability can be linked to original sources.

Meets & exceeds codes & standards

ZETA structures meet and exceed local and State of California building codes and energy efficiency standards for permanent site-built construction and for modular construction. In accordance with the State of California Department of Housing & Community Development's modular housing policies, third-party building inspectors evaluate and provide the seal of approval for off-site construction at ZETA's factory. Local building departments inspect and approve the on-site construction of the foundation, utility connections and the finished home.
