ADU Before & After in Woodland Hills, CA
Anyone can talk about craftsmanship. Seeing a cramped backyard corner become a rentable studio, or a dark garage become a light-filled office, tells the real story. These projects are typical of what we handle across Woodland Hills, from prefab ADU installations to full site-built additions. The photos will be loaded as each job wraps, but the transformations below represent the scope and standard we work to on every project.
Recent Transformations
Detached Garage to One-Bedroom ADU
The problem: a 400-square-foot garage that had become a storage catch-all, with a rotted side door and no insulation to speak of. What we did: we framed out the interior, ran new electrical and plumbing, widened the opening for a proper entrance, and installed a James Hardie cladding exterior so the building finally matched the main house. The result: a rentable one-bedroom unit with a kitchenette, full bath, and its own address-ready entrance. Setback requirements on this lot meant keeping the existing footprint, which a prefab panel system handled cleanly.
Backyard Addition for Multigenerational Living
The problem: aging parents needed to move closer, but the main house had no room to expand without sacrificing the yard entirely. What we did: we designed a two-bedroom site-built ADU tucked along the rear property line, using a Dvele prefab shell to cut on-site framing time nearly in half. The result: a 750-square-foot home with its own laundry, a small patio, and a door that faces the main house’s kitchen window, so family is close without being on top of each other. The written price for this project never moved, from first walkthrough to final inspection.
Home Office Studio Over a Sloped Lot
The problem: the only usable space was a sloped patch of yard where nothing flat could sit without serious grading. What we did: we placed a Mighty Buildings panelized studio on a raised pier foundation, which meant no heavy excavation and no retaining wall. The result: a 350-square-foot workspace with floor-to-ceiling windows facing the canyon, fully insulated for Woodland Hills summers, and permitted as an ADU for future resale value. When a lot has slope, the foundation choice drives the entire budget, and we price that conversation honestly.
JADU Carved from an Oversized Primary Suite
The problem: the house had a primary suite bigger than some apartments, but no legal way to generate rental income from it. What we did: we split the suite, added a kitchenette and a private exterior entrance, and converted one closet into a stackable laundry nook. The result: a fully legal JADU under 500 square feet that rents fast in this area, with zero new foundation work. JADUs, for those unfamiliar with the term, are junior accessory dwelling units built within the walls of an existing home, which usually means a faster permit path than a detached build.
Prefab Two-Bedroom Delivered in Sections
The problem: the homeowner wanted an income property, but a traditional build would have meant six to nine months of construction noise and workers on site daily. What we did: we used an Abodu prefab system, delivered in sections and set with a crane in a single day. The result: a finished two-bedroom, two-bath unit with drywall, paint, and fixtures already in place, hooked up to utilities within two weeks. Prefab is not a compromise on quality; for many lots in Woodland Hills, it’s the smarter math on time and total cost.
Room Addition Over an Old Patio Slab
The problem: a 300-square-foot concrete patio that baked in the afternoon sun and went unused most of the year. What we did: we built a permitted room addition directly onto the existing slab, saving the cost of a new foundation and using Boxabl panel sections for the walls and roof. The result: a climate-controlled family room that added real square footage to the house, with a connected bath and a sliding door that opens onto what remains of the yard. Repurposing a sound slab is one of the simplest ways to keep an addition under budget, when the original pour checks out.
