What is a Prefab ADU?
Picture this: a factory-finished backyard home (two options: 100 sq.ft and 200 sq.ft) that gives you independent living space. No mess, no strangers trampling your garden for months.
Unlike modular ADUs that arrive in sections, prefab units come complete and crane into place.
-
Foundation work managed through trusted partners (screw piles, site prep)
Factory-finished module with Mediterranean craftsmanship
Crane placement and electrical pre-installs ready for connection
Custom built-in furniture designed for your space during fabrication
-
Permits and licenses (you handle these, we provide technical drawings to help)
Typical transformations: Your compact space grows with life's changes. Start with a backyard office, transform to a playroom when kids arrive, then your wellness studio later. Built for every chapter, not just today.

Why Prefab ADUs
Beat Traditional Construction?
-
Traditional builds turn your garden into a construction site. Months of dust, noise, strangers tracking mud through your space. Costs that spiral beyond recognition.
-
Space that feels like home, not a compromised afterthought. Mornings with coffee and quiet, not hammer echoes.
-
Prefab ADUs install in days not months with transparent pricing. No surprises, no delays, no construction chaos.
You know how it goes with traditional builds. Neighbors complain about the noise. Your garden becomes a mud pit. The timeline stretches from "three months" to "we'll see."
Here's the reality: Homes with ADUs often list higher in major metros.
Many homeowners use their ADUs for rental income (exact returns vary by location).
Building prefab cuts timelines significantly while keeping costs predictable compared to traditional construction.
Quick comparison:
Traditional build: 3-6 months onsite, weather delays, coordination headaches
Prefab ADU: 1-2 days install, factory-controlled quality, turnkey service
