Prefab ADUs: Faqs
Still wondering if a Prefab ADU is right for you? You're not alone, and we're here to help. Our FAQ section breaks down the most common questions about Prefab units so you can move forward with confidence.
HUD vs. HCD Certification
HUD-certified prefab ADUs follow federal standards—meaning faster approvals and simpler energy compliance. HCD-certified units meet California codes but often require more complex reviews. ADU Geeks works with HUD-certified providers to streamline permitting.

Customization
While prefab ADUs aren’t fully custom, many offer flexible floor plans, finishes, and upgrade options. ADU Geeks helps match you with a design that suits your style and needs.
Transportation
A prefab unit is craned in when site access is limited or if it needs to be placed in an elevated or hard-to-reach location, while it’s rolled in when there’s clear, level ground and easy access for delivery.
Site Requirements
Prefab ADUs need a foundation, utility hookups, and delivery access. ADU Geeks oversees everything from grading to delivery logistics.
Post-Delivery Setup
After delivery, we handle utility hookups, inspections, and any final touches—staying involved through final sign-off so your ADU is truly move-in ready.
