Dvele Junior ADU & Interior Conversion in West Hollywood: What to Know First
We provide independent Dvele junior ADU and interior conversion work in West Hollywood as an independent Dvele service provider, with most projects moving from signed contract to permit submission in 8-12 weeks and construction following a single written price established before any work begins. A typical basement ADU or room-to-ADU conversion using Dvele’s prefab panel system runs $185,000-$340,000 all-in, drawings through final inspection, with the exact figure locked in writing under Haven Standard Clause 1. This page is for West Hollywood homeowners who bought a Dvele-equipped property between 2019 and 2024 and now need to adapt that interior system to a legal junior ADU - or who are comparing Dvele against Abodu and Cover for an interior conversion and want the actual documentation and price structure they’ll receive.

How Dvele Products Fail - and How We Fix Them
- Dvele S2 Series panel delamination in below-grade installs. The S2’s magnesium oxide sheathing absorbs moisture when the vapor barrier is compromised during a basement ADU conversion, causing edge swelling that throws off interior finish tolerances by 1/8 inch or more. We map the affected panels with thermal imaging, replace only the compromised sections with OEM-grade MGO from Dvele’s supplier network, and reinstall the vapor barrier to ASTM E1745 Class A before closing walls.
- Dvele S3 Smart Home hub failure after electrical service upgrades. The S3’s centralized Loxone hub doesn’t always handshake cleanly with the 200-amp panels common in West Hollywood’s 1920s duplexes after a room-to-ADU conversion adds a subpanel. We isolate the hub on its own circuit, reprogram the topology for split-phase service, and document the new electrical single-line in the permit set so the city inspector sees exactly what changed.
- Dvele One Series HVAC integration gaps in attached addition ADUs. The One Series ships with a Mitsubishi ductless spec that assumes open-plan airflow; when we partition a West Hollywood bungalow into a junior ADU with separate bedroom and living zones, the original cassettes short-cycle. We resize the load calculation per ACCA Manual J, specify additional cassettes or a slim-ducted unit, and coordinate the change order through Dvele’s parts desk before rough-in.
- Dvele window wall misalignment in hillside settle. The Laurel Canyon-adjacent parcels in West Hollywood see seasonal soil movement that shifts the modular window walls in Dvele’s above-garage configurations, breaking the silicone seal and creating water intrusion at the header. We jack and shim to level, replace the compression gasket with a wider-profile OEM part, and reflash with copper panning that accommodates 3/4 inch of future movement.
- Dvele S2 electrical chase obstruction during interior JADU partitioning. The S2’s prefab chases run at 16-inch centers that conflict with new partition walls in a typical West Hollywood 1-bedroom-to-JADU conversion, forcing exposed conduit or drywall teardown. We reroute through the floor cavity where structurally feasible, or specify surface-mounted mini-chase with matching finish - both paths documented in the revised permit set so the inspector follows our logic.
Our Dvele Junior ADU & Interior Conversion Process
- 1
Site survey and Dvele serial verification. We record the unit’s production batch, firmware version, and any prior service tags - this determines parts availability and warranty status before we quote.
- 2
Conditioned-space diagnostics. Moisture meters, thermal imaging, and laser level survey of the existing Dvele envelope; we photograph every reading and send the file within 24 hours.
- 3
Permit-set revision or creation. For conversions where Dvele’s original drawings don’t match as-built conditions - common in West Hollywood’s informal garage conversions from the 1980s - we produce a new permit set that bridges the gap.
- 4
Written price presentation. Every line item is itemized: Dvele OEM parts, compatible aftermarket where OEM is back-ordered, labor, permit fees, and contingency. The total is fixed at signing per Haven Standard Clause 1.
- 5
Construction with documented milestones. Our crews upload dated photos at rough-in, insulation, and final; you see the Dvele panels, the new partitions, and the test results without visiting the site.
- 6
Final inspection and 365-Day Done Right Promise activation. The warranty document references the specific permit number, the Dvele batch code, and the exact scope as permitted - not a generic description.
Before
AfterWhat Dvele Junior ADU & Interior Conversion Costs in West Hollywood
| Scenario | Typical Range | What Moves the Price |
|---|---|---|
| Room-to-ADU conversion, Dvele S2 or S3, no structural change | $185,000-$245,000 | Electrical service upgrade, separate meter requirement, kitchen/bath finish level |
| Basement ADU with Dvele panel remediation | $220,000-$340,000 | Depth of MGO replacement, drainage correction, egress window cut |
| Above-garage ADU, Dvele One Series, hillside settle repair | $265,000-$380,000 | Foundation augmentation, window wall replacement, seismic bracing |
| Attached addition ADU with Dvele HVAC reconfiguration | $240,000-$310,000 | Additional cassettes, ducted unit upgrade, load calc complexity |
These ranges include design, permit set, Dvele-specific parts, labor, and final inspection. What they don’t include: your separate meter application to LADWP, which runs $3,500-$8,000 depending on transformer proximity, or soil testing in the hills above Sunset. We itemize those in writing before you sign. Call (213) 329-7167 for an exact quote - estimates are free.
Why West Hollywood Homeowners Call Ellery ADU Studio West Hollywood for Dvele Work
We’ve specified and coordinated Dvele, Abodu, and Cover systems since 2015, and the difference shows up in the permit set - ours include the Dvele batch code, the revised electrical single-line, and the vapor barrier detail the inspector actually wants to see, not a generic note that sends you back for corrections. Nadia Ellery grew up watching her father argue with contractors over permit drawings that never matched the wall; she built Ellery ADU Studio so that argument doesn’t happen on our sites. The 365-Day Done Right Promise is in writing before the first panel is touched. A live person answers (213) 329-7167 at any hour, and if you already have a written estimate from another firm, we’ll give you a free second opinion with no obligation to hire. The document is the promise. Everything else is a conversation.
FAQs
Structural modifications performed by an independent Dvele service provider typically void the original equipment warranty on affected components, though Dvele often honors the shell warranty if the work is documented with their parts desk and the revised drawings are submitted to their technical review. We handle that submission as part of our permit coordination - call (213) 329-7167 to confirm your batch’s status.
Dvele’s S3 smart-home components and certain window wall gaskets have run 6-10 weeks from order since late 2024; we maintain relationships with their parts desk and two verified aftermarket suppliers for compatible MGO sheathing and compression seals. If your project timeline is fixed, we quote both paths in writing so you choose before signing.
Replacement makes sense when more than 30% of the panel envelope is compromised or when the original electrical and HVAC specs can’t meet current Title 24 requirements for a separate dwelling unit; repair is viable for localized moisture damage or partition conflicts with intact core systems. We give you both numbers, with the repair scoped as a separate line item you can accept or decline.
Permit review at West Hollywood’s Building Division runs 6-8 weeks for junior ADUs with complete documentation; our record is 4 weeks when the original Dvele drawings are on file and no variances are needed. Construction duration ranges 10-16 weeks depending on finish complexity. We don’t promise speed we can’t document - the schedule is in writing, with milestone dates, before work starts.
Yes - we specify and coordinate Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie systems under the same single-contract model, and we’ll compare the three brands’ interior conversion suitability for your specific West Hollywood parcel during the free estimate. Call (213) 329-7167 to schedule.
