Why Lodgewick ADU Builders Is Van Nuys’s Preferred ADU Builders Company

Our ADU Builders team has spent years in the San Fernando Valley, and Van Nuys work makes up a meaningful share of it. The housing stock here tells us what we’ll find before we open a wall: 1950s stucco ranches, detached two-car garages on rectangular lots, cloth-wrapped wiring, and slabs that have shifted over six decades. That local familiarity means we quote honestly, include allowances for the surprises that old garages hide, and do not send you a change order without a written price you’ve approved.

Russ Delmar leads our team. He has walked hundreds of Van Nuys lots, from the neighborhoods north of Victory to the blocks east of Van Nuys Boulevard. Homeowners here call us because they’ve been burned before: a contractor quoted one number, showed up late, and left the job half-finished. We work the opposite way. The Kingswell Way means we say the price before the work, show up in the window given, leave the place cleaner than we found it, put the guarantee in writing, and come back if something fails within 365 days. That is the 365-Day Done Right Promise, and it is on every contract.

JADU in Van Nuys

A JADU (Junior Accessory Dwelling Unit) is a small, self-contained living space carved out of an existing home in Van Nuys, commonly a converted bedroom with a kitchenette and its own entrance, and it is the fastest, least expensive legal way to add a rentable or multigenerational unit on your lot.

Van Nuys sits inside the City of Los Angeles, which allows a homeowner to stack a detached ADU plus a JADU on the same single-family parcel. That is two rental units on one lot, legally, something neighboring Burbank and Glendale make considerably harder under their more restrictive ordinances. On the large postwar R1 lots that dominate Van Nuys, commonly 6,000 to 9,000 square feet, a JADU attached to the main house plus a detached ADU in the converted garage is a real income play.

A JADU in Van Nuys typically runs $35,000 to $80,000 depending on whether you need a new entrance, plumbing for a kitchenette, and Title 24-compliant ventilation. Since the space already exists inside your home’s footprint, you avoid the higher costs of ground-up construction.

When the Main House Has an Underused Room

If you have a spare bedroom, den, or formal dining room that nobody uses, a JADU conversion turns dead square footage into income. We frame the new entrance, add the compact kitchen, and upgrade the electrical so the unit can meter separately if you choose.

Multigenerational Living Without a Separate Build

Families who want aging parents close but not sharing a kitchen use JADUs heavily in Van Nuys. The unit has its own door and cooking space, so independence is preserved without the cost and timeline of a detached structure.

ADU Plans in Van Nuys

ADU Plans in Van Nuys are the architectural and engineering drawings required by the LA Department of Building and Safety before any permit is issued, and getting them right on the first submission is what separates a six-month project from an eighteen-month one.

The Vale of Van Nuys carries a specific advantage: if your existing detached garage already clears the 4-foot side and rear setbacks under LA’s current code, your project qualifies as a conversion rather than new construction. That unlocks LA’s expedited review track and skips the standard plan-check queue. Experienced Van Nuys ADU contractors check this before drawing a single line. We do too, and it saves months.

Plan sets for a Van Nuys ADU typically run $4,500 to $12,000 depending on whether you are converting a garage, building detached, or installing a prefab unit like an Abodu or Cover model. Structural engineering, Title 24 energy calculations, and site plans are included in our written quote.

Garage Conversion Plans on Existing Slabs

Many 1950s Van Nuys garages sit on slabs that already meet current setback rules. If the slab is level and intact, we can draw plans around the existing footprint, compressing both budget and timeline significantly compared to a ground-up build.

Prefab and Modular Plan Coordination

When a homeowner chooses a prefab ADU from Dvele or a modular unit from Mighty Buildings, the manufacturer provides base plans and we handle the local adaptation: foundation engineering for Valley soil, utility connections, and LA-specific plan check submittal.

Trusted Brands We Service in Van Nuys

Our Van Nuys crews work regularly with Abodu, Cover, and James Hardie materials. Abodu units are a strong fit for the rectangular lots and flat or gently sloped pads common here. Cover prefabs handle the thermal-bowl heat well when specified with the right glazing and insulation package. James Hardie siding and trim hold up against Van Nuys sun exposure and the dry heat cycling that breaks down lesser materials. When you need parts, replacements, warranty support, or a seamless installation of one of these systems, we already know the product lines and the local conditions they have to survive.

Common ADU Builders Problems We See in Van Nuys Homes

• 1950s cloth-wrapped wiring hidden in garages. We open walls on Van Nuys garage conversions and find original cloth-insulated wire that is brittle and unsafe by current code. It has to go, and a good written quote includes an allowance for that before the first wall is opened.
• Undersized mini-splits specced for coastal cooling loads. A 9,000 BTU mini-split that cools a Santa Monica ADU will not keep a Van Nuys ADU livable when it is 108°F outside. We size for the thermal bowl, and that means bigger units and Title 24 compliance that actually works.
• Cracked or out-of-level slabs on old detached garages. Six decades of Valley soil movement leaves many Van Nuys garage slabs unsuitable for direct conversion. We inspect first, and if the slab fails, the repair is priced and approved in writing before we pour or build.
• Assuming every garage qualifies for conversion review. Not every detached garage clears LA’s 4-foot side and rear setbacks. We verify the actual survey before plans are drawn, because a failed qualification means a ground-up new-construction plan check and months of delay.
