PreFab Innovations, Inc. — CSLB #1078820

We build on-site using the ZeroCut Building System. Welcome Home.

Panelized walls, integrated solar, SIP roof installed in 1/4 of the time. High-speed homes delivered to the site and installed by our crews, engineered to code as a site-built assembly.

The system

What the ZeroCut Building System is.

The ZeroCut Building System uses a ZeroCut e-SIP (enhanced - Structural Integrated Panel), bathroom/kitchen cores and a SIP Solar Roof our founder invented and co-owns through FBX, and which PreFab Innovations is licensed to build with.

  • Cold-formed steel framing

    A code-recognized CFS section on a standard 24" module. Straight, dimensionally stable, and specified by an engineer of record on each project.

  • Continuous insulation

    A continuous insulation layer runs across the exterior face, uninterrupted by fasteners through the primary studs.

  • Factory-bonded air barrier

    The air barrier is bonded to the panel before it leaves the shop. The outer cladding half is installed last, on site — which is what lets any licensed contractor build it and keeps it on the site-built side of the code.

  • Faster than stick framing

    Walls arrive as panels, so the framing step is an install step. The mechanism is fewer on-site operations, not a promised time figure.

ZeroCut e-SIP panels use non-combustible fiber-cement cladding that meets the deemed-to-comply exterior covering requirement under IWUIC and California Chapter 7A.

Who it's for

Three kinds of clients.

Homeowners

Building a primary residence, a replacement home, or an ADU on a lot you already own.

Developers

Small-to-mid infill projects and single-family portfolios where a repeatable wall assembly matters.

Licensed contractors

PFI builds directly and also trains and supports other GCs on the ZeroCut Building System through FBX.

How we work

Four steps.

A calm, sequential process. No timeline promises.

  1. 01Design & engineeringArchitectural plans are resolved into a ZeroCut e-SIP panel schedule. Structural engineering is completed by the engineer of record.
  2. 02PermitPlan set is submitted to the authority having jurisdiction as a site-built assembly. We respond to plan-check comments and revise as needed.
  3. 03Panel deliveryPanels are produced to the approved schedule and delivered to the site.
  4. 04On-site assemblyOur crews set the panels, complete the outer cladding half on site, and hand the shell to interior trades.

Models

A catalog of site-built homes.

Every model is site-built from ZeroCut factory components — ZeroCut e-SIP wall panels, kitchen and bath cores, Solar SIP roof. Local crews, ordinary local inspections.
