Dvele ADU Site Prep & Utilities in Burbank: What to Know First
We provide independent Dvele ADU site prep and utilities in Burbank, typically completing utility tie-ins and foundation work within 3-6 weeks of permit release. Foundation and grading for a Dvele unit generally runs $18,000-$34,000 all-in, electrical panel upgrades $4,200-$8,500, and plumbing laterals $3,800-$7,200 - every figure written before we step on site, per Haven Standard Clause 1. This page is for Burbank homeowners who have purchased or are considering a Dvele prefab ADU and need a local design-build studio that can coordinate the site prep, utility extensions, and final tie-ins under one contract at one written price.

How Dvele Products Fail - and How We Fix Them
- Foundation misalignment on Dvele One series units. The One series ships with a steel chassis designed for a 6-inch reinforced slab with post-tension cable clearance. In Burbank’s Magnolia Park neighborhood, we’ve found older properties with 4-inch slabs from the 1940s-50s that don’t provide the dead-load distribution the chassis expects. We specify a slab retrofit with grade beams at the bearing points, documented in the permit set before the Dvele unit ever leaves the factory.
- Electrical service undersizing on Dvele Plus models with dual-zone HVAC. The Plus series draws 200A when both heat pump zones run concurrently, but many Burbank homes in the hills above Glenoaks still have 100A panels from original construction. We pull a separate load calculation for the ADU, not just the main house, and specify the panel upgrade in the initial scope - no surprise change order when the electrician arrives.
- Gas line pressure drop on Dvele units with tankless water heater packages. Dvele’s tankless spec requires 2 PSI minimum at the unit, but Burbank’s older 1/2-inch steel laterals often deliver 8-10 inches water column at the property line. We pressure-test the existing lateral during our first site visit, and if it won’t hold, we spec a new polyethylene line with an independent regulator - not a band-aid boost at the unit.
- Drainage conflict with Dvele’s flat-roof scupper system. The Dvele Two series uses integrated scupper drains that discharge at grade, but Burbank’s clay-heavy soil in the foothills doesn’t percolate fast enough during winter storms. We redesign the site drainage with a dry well or trench drain, tied into the permit set, so the scupper doesn’t backflow against the unit’s weather barrier.
- Sewer lateral root intrusion on hillside Burbank lots. Dvele’s wet-bath modules require a 3-inch gravity sewer with 1/4-inch-per-foot fall minimum. On properties above Sunset Canyon, we’ve found original clay laterals collapsed by oak root intrusion that drop below grade. We camera the line, document the blockage, and spec a trenchless replacement or directional bore - whichever the topography allows - before the Dvele crane date is set.
Our Dvele ADU Site Prep & Utilities Process
- 1
Site survey with documented photo record. We photograph existing utilities, slab condition, and access constraints - the Dvele unit arrives on a flatbed, so we measure gate clearances and crane swing radius before anything is ordered.
- 2
Load calculation and utility capacity check. We run the Dvele spec sheet against your existing service, not just the city minimum. If the panel, gas meter, or sewer lateral won’t handle the unit’s demand, we say so now, with a dollar figure attached.
- 3
Permit set including Dvele-specific tie-in details. Our drawings call out the exact connection points, clearances, and finishes the Dvele installation manual requires - no generic detail that the inspector rejects because it doesn’t match the factory spec.
- 4
Utility rough-in and foundation prep. We coordinate water, sewer, gas, and electrical to stub precisely where the Dvele chassis expects them, with sleeve and conduit sizes verified against the latest Dvele shop drawings.
- 5
Final tie-in and commissioning. After the Dvele unit is set, we make final connections, test every system under load, and provide the documented photo record of completed work - what was found, what was done, what it looked like after.
- 6
365-Day Done Right Promise activation. If the finished utility work doesn’t match the permitted drawings, we make it right - in writing, before the project starts, under Haven Standard Clause 6.

| Electrical panel upgrade + ADU subpanel | $4,200-$8,500 | Main service distance, trench length, Burbank DWP coordination timeline |
| Plumbing lateral (water + sewer) | $3,800-$7,200 | Depth to city main, trenching vs. directional bore, root intrusion repair |
| Gas line extension | $2,400-$5,600 | Pressure upgrade needed, line size, SoCalGas meter relocation |
| Landscaping & hardscape (post-set) | $4,500-$12,000 | Decking, walkways, drainage integration with Dvele scuppers |
These ranges reflect Burbank’s specific permit fees, soil conditions, and utility coordination timelines - not national averages. The number goes on paper first. Everything else follows from that. Call (747) 322-4648 for an exact quote; estimates are free.
Why Burbank Homeowners Call Ellery ADU Studio Burbank for Dvele Work
We’ve specified and coordinated Dvele, Abodu, and Cover systems since 2015 - the year California’s ADU laws shifted - and we understand where each brand’s documentation ends and the local site work begins. Our crews have pulled permits and framed units in Magnolia Park as often as anywhere else in Burbank. Every project carries a written price before work starts (Haven Standard, Clause 1), a documented photo record on every visit, and the 365-Day Done Right Promise backed in writing. A live person answers calls 24/7. If you already have a written estimate in hand, we’ll give you a free second opinion - no obligation, no pressure.
FAQs
Yes, if the work is performed to Dvele’s published installation requirements. As an independent Dvele service provider, we follow the factory tie-in specifications exactly - our permit set references Dvele’s shop drawings by revision date - so your structural and systems warranty remains intact. Call (747) 322-4648 to review how we document compliance.
Utility rough-in typically takes 2-3 weeks after permit release, assuming Burbank Building and Safety has no plan-check revision requests. DWP and SoCalGas coordination adds 1-2 weeks for meter scheduling. We build that timeline into your written scope so the Dvele delivery date doesn’t slip. Call (747) 322-4648 for a schedule tied to your specific property.
Replace it if the camera inspection shows root intrusion, offset joints, or slope reversal - any of which will fail under the increased daily flow of a full ADU. We include the camera inspection in our initial site survey and tell you exactly what we found, not what we felt. Call (747) 322-4648 to schedule the inspection.
We use Dvele-specified connection hardware where the factory requires it - typically the chassis anchor bolts and weather-seal gaskets - and quality aftermarket where code compliance is the only requirement, such as conduit, pipe, and junction boxes. We document which is which in your photo record, so there’s no ambiguity at inspection. Call (747) 322-4648 to review the parts list for your project.
We measure gate width, overhead clearance, and crane swing radius during the first site visit and specify a mini-crane or tilt-bed delivery if standard boom placement won’t work. In Magnolia Park, we’ve used alley access with a 90-ton crawler for tight lots - the solution goes in the permit set, not in a conversation after the truck arrives. Call (747) 322-4648 to walk your access with us.
