Precision-engineered.
Built to last a lifetime.
Every Karlev ADU is factory-built to commercial standards, then delivered turnkey, a level of consistency you cannot achieve on a traditional job site.
Solar-ready ceiling and heat-pump mini-split systems. Panels optional.
R-24 exterior walls, R-41 roof, and Marvin Elevate double-pane argon-filled windows.
Assembled through openings as narrow as 30 inches. No cranes required, no live-in crews.
Precision, from spaceframe to keys.
A patented aluminum spaceframe.
Every Karlev ADU begins with Karlev's patented aluminum spaceframe, robotically welded in-shop to ±0.5mm tolerances so it fits together without shims on your lot.
Engineered to outlast the site it's placed on.
Karlev ADUs are built to codes that exceed local residential minimums, because the same structure has to work in wildfire country, coastal wind, and seismic zones.
Seismic-Rated Frame
Patented aluminum spaceframe engineered to local seismic requirements, verified under California's Factory-Built Housing Program.
Class-A Fire Assembly
Non-combustible cladding, sealed penetrations, and a Class-A roof rating throughout.
Storm-Ready Envelope
R-24 walls and R-41 roof with Marvin Elevate double-pane argon-filled low-E glazing on every unit.
IAQ + Fresh Air
Whole-home ERV, low-VOC finishes, and continuous outdoor-air flow, every day.
Find the right Karlev for your site.
One price. One team. One finish line.
Insurance-backed coverage on qualified structural defect repair costs for a full decade, so the coverage is there when you need it.
Electrical, plumbing, and mechanical systems, including heating and cooling, covered for two full years.
Construction defects in materials or workmanship, including cabinets, countertops, flooring, paint, and exterior siding.
Permits, foundation spec, and utility connection managed for you.
Delivered through openings as narrow as 30", assembled on site with no cranes, connected and inspected, you walk in with keys.
Panels and inverter can be added at install or any time after.
Full-size living, engineered.
Every backyard is unique. Karlev ADUs deliver the speed of prefab and the finish of custom construction, adapting to each site by design.
Fundamentally better economics
Time is money, whether you're saving it or making it. Our technology delivers a design and build experience radically more efficient than traditional construction.
Karlev is always more affordable than the alternatives, with fixed upfront pricing that removes the risk of going over budget. No surprises. No hidden costs.
Tall ceilings, big windows, open floor plans and airy private porches make Karlev ADUs feel large and energetic, earning more per square foot and keeping tenants longer.
Exceptional everyday living
The Karlev system allows for limitless windows. With 8' tall and up to 16' wide patio doors, your ADU is brimming with daylight.
12, 14' interior heights that aren't possible with other systems, spaces feel drastically larger and more expansive.
We build every client's feedback into our layout process, so our units have unmatched inner circulation and a truly unique indoor / outdoor connection.
Better environmental performance
R-24 exterior walls and R-41 roofs, up to 40% above average insulation, so your ADU stays comfortable in every season.
Double-glazed, argon-filled Marvin Elevate windows give a level of noise insulation you won't want to give up.
Every Karlev ADU ships with a solar-ready ceiling and 250 sf of panel-ready roof area to lower your electricity bill from day one.
Delivery excellence
Living next to a construction site can be a nightmare. A Karlev install is fast, mostly silent, and doesn't require a live-in crew.
A complete Karlev ADU is designed to fit through a 30" opening. No large or expensive cranes, and no risk to your main home.
Karlev integrates the whole build, 3D design through fabrication, around a 6-axis robotic process and a space-frame breakthrough that drives construction speed and flexibility.
