Adding an ADU in Van Nuys means working with flat, flood-adjacent lots, a patchwork of mid-century single-family homes, and a city that processes more ADU permits than almost anywhere else in Los Angeles. We’re Benson ADU Builders, and we build accessory dwelling units, home additions, and room additions across Van Nuys with a written price before any work starts. Most Van Nuys homeowners we talk to want a detached unit in the backyard, a garage conversion, or a second-story addition. Call (903) 568-7222 and you’ll get a live person, not a voicemail loop.
Why Van Nuys Homes Are Different
Van Nuys was built out fast in the 1940s and 1950s, and it shows in good and bad ways. The good: most lots are 5,000 to 7,500 square feet, flat, and rectangular, which makes them easier to work with than hillside parcels in Sherman Oaks or Studio City. The bad: many of those older homes were built on raised foundations with undersized electrical panels, and any ADU that adds a kitchen, mini-split system, or electric dryer will likely need a panel upgrade before the city signs off.
Climate matters here too. Van Nuys routinely posts some of the hottest summer temperatures in the San Fernando Valley, so we spec higher-tonnage mini-splits and recommend light-colored roofing and extra attic insulation on ADU projects. The flat terrain drains slowly after heavy rain, so we check lot grading and set finished floor elevations carefully. And because much of Van Nuys falls within the Van Nuys-North Sherman Oaks Community Plan area, setbacks and ADU placement rules can vary block by block. We handle all of that, but it’s part of why cookie-cutter plans from a website rarely survive first contact with a Van Nuys lot.
Our Main Van Nuys Services
Most Van Nuys homeowners call us about one of three projects: building a new ADU, adding square footage to the main house, or converting an existing room into something more useful. Each has its own dedicated page with pricing, timelines, and Van Nuys-specific details.
ADU Builders in Van Nuys
A detached ADU in Van Nuys usually runs from a 400-square-foot studio to a 1,200-square-foot two-bedroom unit with laundry. The flat lots here make crane and panel delivery straightforward, which is one reason we often recommend prefab systems from Abodu or Cover for Van Nuys backyards. Garage conversions are popular too, especially on streets like Vanowen or Victory where the existing garage sits on a paved alley. Explore what we build on our ADU Builders in Van Nuys page.
Home Addition Contractor in Van Nuys
Home additions in Van Nuys tend to go up rather than out, since side-yard setbacks on standard 50-foot-wide lots swallow up horizontal space quickly. A second-story addition over an existing single-story home is one of the most common requests we hear from families near Van Nuys Boulevard and Sepulveda Basin. Foundation work gets more involved when we’re tying new framing into a 70-year-old raised floor. See Home Addition Contractor in Van Nuys for what that looks like in practice.
Room Addition Contractor in Van Nuys
A room addition typically means a single new bedroom, a bumped-out living room, or an enclosed patio. In Van Nuys, enclosed patios are everywhere, and many were built without permits in the 1960s and 1970s. If you want to bring one up to code or add a permitted bedroom, we’ll assess the foundation and roof tie-in before quoting. Our Room Addition Contractor in Van Nuys page walks through the process and typical costs.

Pricing for ADU Company in Van Nuys, CA
Van Nuys pricing falls in the middle of the Los Angeles range. Flat lots keep site work cheaper than hillside builds, but older panels and flood-zone foundation requirements can add cost on individual properties.
| Service | Typical range in Van Nuys |
|---|---|
| Detached ADU (400 sq ft studio) | $150,000 – $220,000 |
| Detached ADU (750 sq ft one-bedroom) | $180,000 – $260,000 |
| Detached ADU (1,200 sq ft two-bedroom) | $240,000 – $340,000 |
| Garage conversion ADU | $90,000 – $150,000 |
| JADU (existing space conversion) | $60,000 – $100,000 |
| Second-story home addition (400 sq ft) | $180,000 – $260,000 |
| Ground-floor home addition (400 sq ft) | $120,000 – $200,000 |
| Room addition (200 sq ft) | $60,000 – $100,000 |
| Electrical panel upgrade to 200A | $3,000 – $6,000 |
| Foundation retrofit (seismic, raised floor) | $8,000 – $25,000 |
What pushes a Van Nuys project toward the top of those ranges: needing a panel upgrade before the city will pass electrical, flooding-related foundation work near the Sepulveda Basin, or a design that triggers a discretionary review with the planning department. Your written price comes before work starts, and it doesn’t change unless you change the scope. That’s the entire point of how we run projects.
