Why Van Nuys Residents Choose Us for Dvele Service
We’ve worked on Dvele modular and prefab homes across the San Fernando Valley since 2015, including factory-built shells installed on tight Van Nuys alley lots where crane access is the make-or-break detail. Our crew knows the Dvele panelized system, its transport tolerances, and the foundation interfaces that Van Nuys’s post-WWII garage pads often lack. We are an independent design-build studio - not manufacturer-affiliated or authorized - which means we specify what actually works here rather than what a factory manual written for a milder climate recommends.
Nadia Ellery, our owner and principal designer, grew up in Santa Monica and studied architectural drafting and construction technology at Santa Monica College before spending years on residential projects across the Valley. She and our crew have logged serious time in Van Nuys proper, including a stretch of ADU Design & Permitting in Van Nuys near the Van Nuys Civic Center corridor. That ground-level familiarity shows in how she reads a site before anyone picks up a pencil. She keeps every soils report and permit approval her office has ever filed, organized by address, because she believes a client should be able to verify any claim before signing anything. The document either says it or it doesn’t - let’s look at the document.
We stock OEM structural connectors and panel gaskets for Dvele shells locally, and we specify Title 24-compliant mechanical and electrical upgrades that outperform factory defaults in Van Nuys conditions. Every project carries our 365-Day Done Right Promise in writing, and a live person answers calls 24/7.
Common Dvele ADU Problems We Solve in Van Nuys
- Panel seam cracking from thermal expansion. Dvele’s panelized shell expands and contracts more aggressively in Van Nuys’s 100°F+ summers (CEC Climate Zone 9), causing hairline cracks at panel seams if the foundation was not engineered for thermal movement. We see this most on south- and west-facing walls of shells installed by out-of-area crews who didn’t account for the Valley’s 40°F daily temperature swings in summer.
- Failed factory weather sealant. The factory-applied sealant on Dvele modules often dries out within 2-3 years on Van Nuys’s south- and west-facing walls, leading to water intrusion around window and door openings that the factory warranty may not cover after installation. We re-flash these seams with Zone 9-rated materials during our first service visit.
- Undersized mechanical chases. Dvele’s default chase is sized for coastal climates and leaves little room for the larger HVAC tonnage and deeper Title 24 insulation required in Van Nuys. Many installs end up with units that run constantly and still can’t hold 75°F on a 105°F afternoon. We redesign the chase and upsize the equipment as part of our standard scope.
- Cracked garage slabs under point loads. When Dvele shells are crane-set onto older Van Nuys garage slabs that were never engineered for a concentrated load, we see hairline cracks and differential settlement at module corners within the first year. We evaluate the existing slab before crane day and engineer a new foundation when the numbers don’t work.
- Electrical panel overload. Van Nuys’s 1950s ranch homes typically carry original 100-amp panels. A Dvele’s all-electric heat pump and induction range will trip breakers repeatedly without a 200-amp upgrade. We pull the permit and coordinate the utility connection as part of our single contract.
Before
AfterDvele Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys sits in the floor of the San Fernando Valley, one of the hottest inland microclimates in LA County - regularly running 10-15°F above the westside and frequently exceeding 100°F in summer. This puts every Dvele ADU here under CEC Climate Zone 9, which triggers stricter Title 24 insulation and mechanical requirements than coastal LA. A mini-split sized for a Garage Conversion ADU - Van Nuys will be chronically undersized for the same footprint in Van Nuys. We’ve learned this the hard way on projects, and we now spec every Dvele shell in Van Nuys with a full Manual J load calculation using actual Valley design temperatures, not the factory’s default coastal assumptions.
The other Van Nuys factor that changes everything is the rear-alley network. Most 1950s ranch lots here have detached two-car garages with alley access, which means a Dvele prefab ADU can be crane-set from the alley and given its own separate postal address - a privacy feature that measurably increases achievable rent and is largely absent in hillside or newer-subdivision neighborhoods elsewhere in the Valley. We installed a 600 sq ft Dvele LUMEN shell on a 6,500 sq ft lot near the Van Nuys G Line station, backing onto the alley off Valerio Street. The crew craned it over the existing detached garage and set it on a new engineered slab - the original 100-amp panel had to be upgraded to 200 amps to carry the Dvele’s all-electric heat pump and induction range. Within the first summer we had to add a secondary mini-split head and re-flash the south-facing panel seams, because the factory weather sealant was not rated for 105°F days in Climate Zone 9. That project taught us to front-load the mechanical upgrade and specify aftermarket sealant rated for Valley conditions on every subsequent Van Nuys Dvele install.
Dvele Models & Products We Service in Van Nuys
We specify and coordinate Dvele systems within our single-contract design-build model, covering the full product line: Dvele LUMEN Series, Dvele VERTEX Series, Dvele Custom Modular ADU, and Dvele Prefab ADU (factory-built shell). For structural work, we use OEM connectors and panel gaskets where available - aftermarket replacements rarely match the factory profile, and a mismatched gasket in a Zone 9 thermal cycle will fail. For mechanical, electrical, and finish components, we specify high-quality aftermarket parts: Title 24-compliant mini-split systems, upgraded 200-amp panels, and Valley-rated weather barriers. These are the real weak points in a Van Nuys install, and replacing them is smarter than forcing a coastal-rated OEM part into 105°F afternoons. We keep common Dvele structural hardware in stock locally for fast turnaround on service calls across Van Nuys.
Dvele Service Pricing in Van Nuys
Dvele prefab and modular ADU projects in Van Nuys typically run $180,000-$340,000 all-in, covering design, permit set, Dvele shell specification and coordination, foundation, utility connections, and final inspection. What drives the cost: whether the existing slab can carry the shell or needs replacement; the electrical upgrade from 100 to 200 amps; the mechanical upsizing for Climate Zone 9; and whether crane access from the alley requires street closure permits.
Our free estimate includes a site evaluation, slab assessment, utility capacity check, and written line-item quote - no call-for-pricing runaround, per Haven Standard Clause 1. Every project is quoted with a written price before any work begins. Call (424) 523-8492 for your exact number. Estimates are free.

FAQs - Dvele ADU in Van Nuys
Can a Dvele prefab ADU be delivered and crane-set on a Van Nuys alley lot?
Yes. Van Nuys’s dense rear-alley network behind 1950s ranch lots is ideal for this. The crane can reach the backyard without crossing the main house footprint, and the ADU can receive its own alley-facing address. We’ve completed multiple alley-set Dvele shells in Van Nuys, including one near the G Line station off Valerio Street. Call (424) 523-8492 to check your specific lot access.
Does a Dvele ADU meet Title 24 in Van Nuys’s Climate Zone 9?
The factory shell meets Title 24 baseline, but the default mechanical package is sized for milder climates. We redesign the HVAC and insulation package for Zone 9 compliance on every Van Nuys project. The permit set we produce includes the corrected Manual J and equipment specs. Call (424) 523-8492 to review the documentation.
Will a Dvele modular ADU qualify for the TOC density bonus near the Van Nuys G Line station?
Properties within a half-mile of the Van Nuys and Sepulveda G Line stops qualify for LA’s Transit Oriented Communities density tiers, which can unlock additional unit allowances beyond standard ADU rules. We verify TOC eligibility during our initial site evaluation and adjust the permit strategy accordingly. Call (424) 523-8492 to check your property’s status.
How do you handle the electrical panel upgrade for a Dvele ADU on an older Van Nuys home?
Most Van Nuys homes from the 1950s-1960s have 100-amp panels. A Dvele’s all-electric package requires 200 amps. We pull the permit, coordinate LADWP or SCE disconnect and reconnect, and handle the inspection as part of our single contract. The upgrade typically adds $8,000-$15,000 to the total project. Call (424) 523-8492 for a written quote.
Can a Dvele ADU be placed on an existing detached garage slab in Van Nuys?
Only if the slab was engineered for the point load of a modular shell. Most Van Nuys garage slabs were poured in the 1950s-1960s for a wood-framed structure and will crack under a Dvele module. We core-sample and calculate before crane day. If the numbers don’t work, we engineer a new foundation. Call (424) 523-8492 to schedule the evaluation - estimates are free.
