ADU (Accessory Dwelling Unit) in Van Nuys

Professional adu (accessory dwelling unit) services in Van Nuys, serving homeowners throughout San Fernando Valley. Van Nuys sits on the flat valley floor of the San Fernando Valley, and that flatness shapes almost every job you will take on here. The soil is largely alluvial, deposited over centuries by the Los Angeles River system, which means expansive clay is common and you should expect soil reports to drive foundation decisions on any significant addition or new build. The housing stock runs heavily toward post-war single-family homes built through the 1950s and 1960s, so you will regularly encounter original galvanized plumbing, knob-and-tube or early aluminum wiring, and wood-frame construction that was built before modern seismic standards, all of which tend to surface once walls open up. The inland valley climate brings genuine temperature swings, with summer heat regularly pushing well past 100 degrees, so HVAC sizing, attic ventilation, and radiant barrier details matter more here than they would closer to the coast. Lots are generally rectangular and accessible from the street without the grade changes you find in hillside neighborhoods, but alley-facing garages are common, and ADU work in the rear yard is something worth confirming locally given how frequently those projects come up in this part of the valley. Los Angeles County holds dozens of incorporated cities, and each one runs its own building department, so the submittal package, the number of plan check rounds, and the fee schedule for the same kitchen remodel can look different a few miles down the road. Homes in unincorporated pockets go through the county rather than a city, and the mailing address does not always tell you which one has jurisdiction, so settle that first. Your local building department can tell you which trades need separate permits, whether the lot falls in a hillside, flood, or fire hazard overlay, and whether a soils or structural report has to come in with the plans. One statewide ADU law sits under all of it, but the objective design standards layered on top are written city by city. Common home styles in the area include 1950s post-war stucco tract homes on slab foundations, 1960s to 70s apartment complexes with shared-wall construction, 1940s minimal-traditional cottages on narrow rectangular lots.
