We provide independent Dvele prefab ADU service across Oak Hills, from ADU Design & Permitting - Oak Hills and shell set to utility tie-in, Title 24 compliance, and final County inspection.

Why Oak Hills Residents Choose Us for Dvele Service
We’ve set, wired, and commissioned Dvele panelized shells on large rural lots from Ranchero Road to the equestrian parcels south of the 15, so we know how the LUMEN’s high-R envelope and factory utility chases behave when summer afternoons hit 105°F and winter nights drop below freezing. Dvele sales & service is a core competency here, not an add-on.
Nadia Ellery, our owner, grew up in Santa Monica watching her grandfather argue with contractors over concrete pour schedules. She studied architectural drafting and construction technology at Santa Monica College before spending over a decade in the field. That background shows up in how we spec Dvele jobs: every scope is itemized, every price is written before you sign, and we keep a battered copy of the San Bernardino County grading standards on the desk for when a subcontractor’s estimate doesn’t add up. The number goes on the page before the conversation ends - that’s not a policy, it’s just how decisions get made.
We’re an independent Dvele service provider. Not affiliated with, endorsed by, or authorized by the manufacturer. That independence means we source OEM-compatible parts where they matter - structural connectors, panel gaskets, weather-sealing tape - and use quality equivalents for commodity items like breakers and filters. Your warranty status with Dvele is between you and them; our job is making the shell perform in Oak Hills conditions.
Common Dvele ADU Problems We Solve in Oak Hills
- HRV/ERV pre-filter clogging from desert dust. Dvele’s factory ventilation ducting uses low-profile runs that trap blowing sand and fine Mojave dust. In Oak Hills, we find elevated CO2 and stale master-suite air within one heating season on LUMEN units. We clean the runs, upgrade to higher-capacity pre-filters, and adjust the balance for our particulate load.
- Panel joint air leaks from extreme diurnal swings. Oak Hills sees 100°F afternoons and below-freezing nights, sometimes within 24 hours. That repeated expansion and contraction opens hairline gaps at panel seams and window tape. We pressure-test, re-tape with compatible high-temp sealant, and verify with a second blower-door run.
- Factory electrical chase undersized for real loads. Dvele shells arrive with chases sized for light residential use. Adding a 240V mini-split, electric range, or dryer in an Oak Hills detached install routinely requires a service and panel upgrade the owner didn’t plan for. We catch this in the free estimate, not after the shell is set.
- Freeze splits in exposed plumbing stub-outs. Factory plumbing on detached units often lacks adequate freeze protection. When Oak Hills nights drop below freezing, exposed fill lines from a private well manifold split - usually behind a cabinet the owner never checked. We insulate, heat-trace, and relocate vulnerable runs.
- Septic system overload blocking County sign-off. Because virtually every Oak Hills parcel runs private septic, adding an ADU bedroom and kitchen triggers a San Bernardino County Environmental Health load calculation. We’ve seen percolation tests fail and owners need second leach fields. We flag this risk upfront and coordinate the test early.
Dvele Service in Oak Hills: What Local Conditions Mean for Your Equipment
Here’s the Oak Hills reality that doesn’t show up on Dvele’s spec sheet: this is an unincorporated community where virtually every parcel relies on private septic and, frequently, a private well. That means your ADU permit doesn’t stop at San Bernardino County Building & Safety. It also lands on the desk of County Environmental Health, which will demand a septic capacity evaluation - and often a percolation test, load calculation, or system expansion - before they’ll sign off on habitation. A significant share of parcels need a well-yield test too. This dual-infrastructure review loop is the real pacing item on Oak Hills ADU permits, not lot size. While a Victorville project on municipal sewer and water might clear in a single review cycle, an Oak Hills Dvele install routinely touches two County departments with separate timelines, separate fees, and separate inspection schedules. We build that loop into our project schedules and our written prices from day one. Oak Hills service area coverage means knowing which County inspector will ask to see the well log before the shell ever leaves the truck.

FAQs - Dvele ADU in Oak Hills
Yes. Because Oak Hills is unincorporated San Bernardino County with virtually no municipal sewer coverage, your ADU permit - including a Garage Conversion ADU in Oak Hills - requires County Environmental Health sign-off on septic capacity, often a percolation test or load calculation, and frequently a well-yield test if you’re on private water. This dual review adds time and cost that sewer-and-water cities don’t face. Call (760) 493-7752 and we’ll walk through your parcel’s specific requirements - estimates are free.
Yes, with proper site adaptation. Dvele’s factory high-R panels exceed baseline Title 24 requirements, but the High Desert’s extreme temperature swings demand careful attention to seam sealing and HVAC sizing. We commission every Oak Hills unit with a blower-door test and verify the mini-split is sized for the load - not the factory default. Our field results: clean Title 24 passes on second County review, every time.
Often, no. Dvele’s factory electrical chases are sized for light residential loads. Adding a 240V mini-split, electric range, or dryer in an Oak Hills detached install typically requires pulling a heavier feed and upsizing to a 200A service panel. We catch this in the free estimate and include the upgrade as a written line item before you sign. No surprises after the shell arrives.
We insulate exposed stub-outs, install heat-trace cable on vulnerable runs from the well manifold, and relocate lines out of exterior walls where possible. Oak Hills winter nights regularly drop below freezing, and factory plumbing on detached units often lacks adequate protection. We pressure-test the system before and after freeze season. Call (760) 493-7752 to schedule an inspection - estimates are free.
No. We are an independent Dvele service provider - not affiliated with, endorsed by, or authorized by Dvele. We source OEM-compatible parts where structural integrity or weather sealing is at stake, and quality equivalents for commodity items. Your Dvele factory warranty is between you and the manufacturer; our work is warrantied under our 365-Day Done Right Promise, backed in writing.
