Detached ADUs
400–1,200 sq ft standalone backyard homes
The most popular project in California. We site the unit to meet state-mandated 4-foot setbacks, orient windows and doors for light and privacy, and design around your yard's drainage and utility runs. Every detached ADU is engineered for your city's snow, wind and seismic requirements — nothing cookie-cutter.

Garage Conversions
Turn an unused garage into a legal rental
The fastest, lowest-cost path to a new unit. California law prohibits cities from requiring replacement parking, so your garage can become a studio or 1-bedroom with its own kitchen, bathroom and entrance. We handle the foundation check, new utility separations, insulation, and the complete interior build-out.

- ✓Full interior build-out

Attached ADUs
Additions with a private entrance
Ideal for multigenerational living or when your lot is tight. An attached ADU shares a wall with the main house, which lowers construction cost per square foot while giving everyone privacy. We detail the fire separation, sound insulation and separate entry so it feels like its own home.

Junior ADUs (JADUs)
Up to 500 sq ft inside your existing home
Carved from an existing bedroom, den or attached garage, a junior ADU is the most affordable way to add a legal rental. State law lets JADUs share sanitation facilities with the main house, which keeps plumbing costs minimal. Owner-occupancy applies, but many cities waive it for JADUs.
- ✓Floor plan feasibility review
- ✓JADU plan set
- ✓Kitchenette & bath design
- ✓Exit & egress compliance
- ✓Permit submittal
- ✓Interior build-out
3–5 months from first call to move-in
Two-Story ADUs
Maximize small lots with vertical space
When your backyard can't fit a wide footprint, a two-story ADU doubles living space on the same foundation. We design compact stair layouts, upstairs decks and setbacks that clear second-story plane limits common in older California neighborhoods.
- ✓Height & setback study
- ✓Two-story plan set
- ✓Structural & foundation engineering
- ✓Title 24 energy calculations
- ✓Permit submittal & corrections
