We’ve worked the flat, grid-pattern lots of Van Nuys since 2015 - the year California’s ADU laws shifted - and we know the difference between a ranch on a 6,000 sq ft lot near Van Nuys Boulevard and a property tucked against the G Line corridor. Our crews serve Van Nuys locally, with dispatch and scheduling coordinated from our Los Angeles office. That local familiarity matters when your 1950s home has a 100-amp panel, original galvanized plumbing, and an alley that could give your ADU its own separate postal address.

Why Ellery ADU Studio Van Nuys Is Van Nuys’s Preferred Garage Conversion ADU Company

We’ve designed, permitted, and built 900-plus ADUs since 2015, and a significant share of them sit on Van Nuys lots. Homeowners here find us because we name dollar ranges on the page, document every visit with photos, and back our work with the 365-Day Done Right Promise in writing. Our Garage Conversion ADU team doesn’t subcontract the design to one firm and the build to another; one contract, one written price, one party responsible.

Van Nuys customers specifically mention our permit-set thoroughness in reviews. The City of Los Angeles plan check is rigorous, and a returned submittal adds weeks. We build the set as the core product, not an afterthought, which is why our Van Nuys projects clear plan check faster than the regional average.

Response time to Van Nuys is same-day or next-day for initial consultations. We’re not crossing the hill from the westside; our crews work the Valley regularly and understand that a 100°F July day in Van Nuys changes what “standard” HVAC sizing means.

Local knowledge that builds trust: we know which Van Nuys blocks have rear alleys wide enough for construction access, where the 100-year flood zone touches certain pockets near the LA River, and which properties within a half-mile of the Van Nuys or Sepulveda G Line stops qualify for Transit Oriented Communities density tiers. That knowledge changes what’s possible on your lot.

Our Garage Conversion ADU Services in Van Nuys

Detached Garage Conversion

Detached two-car garages are the single most common conversion scenario in Van Nuys, and for good reason. The flat, alley-served grid of 1950s-1960s lots means your converted garage can receive its own separate postal address off the rear alley - a privacy feature that measurably increases achievable rent and is largely absent in hillside or newer-subdivision neighborhoods elsewhere in the Valley. We handle the full scope: foundation assessment, electrical service upgrade from that original 100-amp panel, Title 24 energy compliance for CEC Climate Zone 9, and the permit set that gets you a certificate of occupancy. Typical range in Van Nuys: $110,000-$165,000.

Attached Garage Conversion

Attached garages in Van Nuys ranches present a different puzzle. The shared wall with the main house means fire separation, sound transmission, and sometimes structural tie-in questions that detached conversions avoid. We address these in the permit set upfront, not during construction. On a recent project near Victory Boulevard, we separated the utilities entirely so the ADU could meter independently - a detail that pays off for rental income documentation. Typical range: $85,000-$135,000.

Garage Partition & Bathroom Add

Not every Van Nuys homeowner wants a full ADU. Some need a guest suite, home office, or caregiver quarters with a bathroom and kitchenette but without the full permit burden of a separate dwelling unit. We partition existing garage space, add wet walls and mechanical, and deliver a functional addition that may or may not require full ADU compliance depending on your goals. The key is scoping it correctly before any walls open. Typical range: $45,000-$85,000.

Garage JADU (Junior ADU)

A Junior ADU is contained entirely within the existing walls of your home or attached garage, with no expansion of footprint. In Van Nuys, this often means converting half an attached two-car garage while keeping the other half for storage or parking. JADUs have relaxed parking and setback rules, but they still need a kitchenette, separate entrance, and owner-occupancy of either the main house or the JADU. We handle the code analysis to confirm your specific property qualifies. Typical range: $65,000-$110,000.

Carport Conversion

Van Nuys has fewer carports than garages, but they’re present on some 1940s-era lots and mid-century infill. Converting a carport to an ADU requires adding walls, insulation, and often a new foundation where there was only a slab or dirt floor. We assess the existing structure’s capacity to carry roof loads and specify Tuff Shed or site-built framing accordingly. Typical range: $75,000-$125,000.

Trusted Brands We Service in Van Nuys

Ellery ADU Studio specifies and coordinates prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie - all within the same single contract that covers your design, permit set, and construction. For Van Nuys’s CEC Climate Zone 9 conditions, we frequently recommend James Hardie siding for alley-facing elevations: it handles the thermal cycling of 100°F-plus summers without the warping or paint failure we see on lesser materials. Tuff Shed’s engineered garage packages adapt well to Van Nuys’s flat lots when a full custom build isn’t necessary. We don’t push brands; we specify what performs for your specific lot, climate, and rental goals.

Common Garage Conversion ADU Problems We See in Van Nuys Homes

• 100-amp electrical panels that won’t carry ADU load. Van Nuys’s post-WWII housing stock commonly has original 100-amp service. We upgrade to 200 amps as part of the permit set, not as a surprise change order. Retrofitting later, after walls are closed, costs 40-60% more than scoping it upfront.
• HVAC sized for coastal LA, failing in Van Nuys heat. Equipment selected for Santa Monica or Venice will run short here. CEC Climate Zone 9 triggers stricter Title 24 insulation and mechanical requirements, and we size for 100°F-plus days - because tenants don’t care that the same unit “works fine in Marina del Rey.”
• Missed TOC tier eligibility near G Line stops. Properties within a half-mile of the Van Nuys or Sepulveda Metro G Line stations qualify for density bonuses many homeowners never learn about until after permits are filed. We check this in our first site analysis; waiting means redesigning or losing extra unit allowances entirely.
• Alley drainage ignored until it floods. With no rear driveway or with grading that pushes water toward the alley, a beautifully converted garage ADU can have an unusable private entrance three months a year. We assess drainage patterns during site visit one, not after the first rain.
