Why a Prefab ADU?

A Pre-fabricated ADU is built off-site in a factory, then delivered and installed in your backyard. Prefab ADUs use streamlined, factory-controlled construction, standardized designs, and reduced on-site labor.

  • Faster Construction

    The estimated timeline to build a Pre-Fab ADU is ~3-4 weeks after permitting compared to an estimated timeline of 2-3 months for a traditional single-story ADU

  • Cost-Effective

    Prefab ADUs cost roughly 25-36% less per sqft than stick builds for material and labor costs

  • Sustainable

    Factory production optimizes materials, reducing excess waste

  • HUD-Certified

    Our Prefabs are federally certified by HUD so you can bypass state energy requirements for faster approvals.

  • Less On-Site Disruption

    Most of the work happens off-site, which means less noise, mess, and inconvenience at your property.

  • Quality Control

    Using repeatable processes and skilled teams, we deliver consistent craftsmanship and quality
