Dvele ADU in Home Gardens, CA | Ellery ADU Studio Corona
We provide independent Dvele service across Home Gardens, unincorporated Riverside County’s tight-lot community where every ADU permit routes through County Building & Safety, not Corona’s city hall. Our Dvele work here differs because we build permit packages to the County Land Use Ordinance from day one - no refiling, no lost weeks.

Why Home Gardens Residents Choose Us for Dvele Service
We’ve focused our ADU practice on Dvele’s factory-built modular and panelized systems since before most contractors in Riverside County had heard of them. That means we know how their wall panels, utility chases, and roof assemblies behave once they’re craned onto a tight Home Gardens lot - and we know where their install sequence diverges from conventional site-built construction.
Nadia Ellery, our owner, grew up in Santa Monica helping her uncle reroof bungalows two blocks from the pier. She studied construction technology at Santa Monica College before moving into design-build work. Over the past several years she and our crew have completed ADU projects across Corona, including a detached studio on a tight lot near Green River Road that required three separate variance conversations with the city before the permit cleared. That experience with stubborn permitting translates directly to Home Gardens, where Riverside County’s unincorporated process demands the same patience and documentation discipline.
We source Dvele OEM panels, connectors, and gaskets for structural and envelope work. Aftermarket substitutes won’t match their engineered tolerances. For electrical and mechanical components where the spec allows, we use quality aftermarket parts to keep your project on budget without compromising what the factory designed. Every project carries a written price before any work starts - Haven Standard, Clause 1 - and our 365-Day Done Right Promise backs the finished product in writing.
“Tell me the lot dimensions and I will tell you what fits - and what it will actually cost.”
Common Dvele ADU Problems We Solve in Home Gardens

- Panel-to-slab gaps on out-of-level garage foundations. Home Gardens’ postwar tract homes often sit on detached garage slabs that settled unevenly over seventy years. Dvele’s wall panels arrive with tight tolerances - sometimes within an eighth of an inch - and an out-of-level slab creates gaps at the panel-to-foundation connection that standard shimming won’t fix. We re-level or re-pour the pad before the modules arrive.
- Compromised envelope seals during small-lot craning. The limited tree canopy and tight setbacks on Home Gardens lots mean Dvele modules get staged closer to fences and existing structures than the factory manual prefers. Panel seams and gasket transitions take knocks. If we don’t catch the damage before utility rough-in, the 100°F summer heat turns that compromised seal into a moisture and infiltration problem that overworks the mini-split.
- Electrical chase mismatches with undersized existing panels. Many Home Gardens homes still run on 100-amp panels installed in the 1960s. Dvele’s standardized electrical chases assume adequate service capacity. When the panel can’t handle the ADU load, the chase layout needs rework and the panel upgrade enters the critical path - something we flag during our first site visit, not after the modules are ordered.
- Utility lateral sizing for gas and water. Older gas laterals on these postwar lots weren’t sized for an additional dwelling unit. Dvele’s plumbing chase assumes predictable pressure and flow. We verify lateral capacity early; replacing a gas lateral after the foundation is poured costs significantly more than doing it during site prep.
- Plan-check corrections from wrong-agency filing. Homeowners who assume they’re in Corona file with the wrong city, lose weeks, then start over with Riverside County. We file correctly the first time, with Dvele documentation adapted to County-specific setback and owner-occupancy requirements.
Before
AfterDvele Service in Home Gardens: What Local Conditions Mean for Your Equipment
Home Gardens is unincorporated, so every Dvele ADU here goes through Riverside County’s Building & Safety and Planning departments, not Corona’s city hall next door - and homeowners who assume otherwise lose weeks refiling. The County’s ADU-specific provisions under the Land Use Ordinance also handle owner-occupancy and utility-connection nuance differently than Corona or Norco, so we build our Dvele permit packages to the County standard from day one - part of our ADU design & permitting - Home Gardens process.
This matters for Dvele owners specifically because the factory’s standard plan sets anticipate municipal code review. Riverside County’s unincorporated process adds a layer: the County verifies that utility connections comply with their standards, not the city’s, and their setback calculations reference the Land Use Ordinance’s unique definitions. We’ve seen Dvele projects where the factory documents showed a compliant side-yard setback under Corona’s code but failed under County measurement rules - a correction that, caught late, delays module delivery and cranes the schedule. Our permit sets include County-specific clarifications before submission, so the plan-check moves straight to approval.
The climate compounds this. Home Gardens sits in the western Inland Empire where summer highs regularly push past 100°F and Santa Ana winds in fall drive rapid temperature swings. A Dvele envelope that passed factory QA in milder Northern California conditions faces real thermal stress here. We specify radiant barriers and right-sized mini-splits as baseline, not upgrades, because a poorly sealed module on a 105°F August afternoon becomes an energy penalty the owner pays for twenty years.
Dvele Models & Products We Service in Home Gardens

We specify and coordinate Dvele sales & service across three model families for Home Gardens properties:
- Dvele LUMO series - studio and one-bedroom modular ADUs, the most common fit for Home Gardens’ 900-1,400 sq ft lots where setback math is tight
- Dvele two-bedroom modular configurations - for larger corner lots that clear the County’s minimum dimensional standards
- Dvele detached prefab ADU packages - complete site-to-finish systems we coordinate under our single design-build contract
Our Home Gardens service area inventory includes Dvele OEM panel connectors, gasket sets, and chase components for same-week repairs. For mini-splits and electrical components where Dvele’s spec allows aftermarket equivalents, we stock quality substitutes that keep your timeline intact without voiding the factory warranty. We do not use generic panels or connectors on structural work - the tolerances are too tight, and the County inspector will flag the mismatch.
Dvele Service Pricing in Home Gardens
Dvele prefab ADU installation in Home Gardens typically runs $185,000-$275,000 all-in, drawings through final inspection, for a LUMO-series studio or one-bedroom module. Foundation and grading work adds $18,000-$35,000 depending on existing slab condition and soil prep needs. Electrical panel upgrades, when required, run $4,500-$8,500 for a 200-amp service with proper grounding to County spec.
What drives cost: slab condition, utility lateral capacity, and the degree of County plan-check revision required. Projects with clean existing slabs and adequate electrical service sit at the lower end. Projects requiring full slab replacement, gas lateral upsizing, and extensive County documentation push higher. Every project receives a written line-item quote before any work begins - Haven Standard, Clause 1 - and the scope locks at signing. No door-side upsells, no scope creep.
Our free estimate includes a site visit, slab assessment, utility capacity check, and preliminary County filing strategy. Call (951) 476-3715 to schedule yours, or bring any written estimate already in hand for our Free Second Opinion.

FAQs - Dvele ADU in Home Gardens
Riverside County. Home Gardens is an unincorporated census-designated place, not an incorporated city. Every ADU permit routes through County Building & Safety and Planning departments. Homeowners who file with Corona’s city hall waste weeks before discovering the error. We file correctly the first time. Call (951) 476-3715 if you’re unsure which jurisdiction applies to your property - we’ll verify it during your free estimate.
Yes, and it’s the most common scenario we handle. Most Home Gardens lots have postwar detached garages on slab. We assess slab flatness, re-level or re-pour as needed, then crane the Dvele modules into place. On a tight lot off Magnolia Avenue, our crew installed a Dvele LUMO studio behind a 1950s tract home whose garage slab was out of level by nearly two inches - we re-poured with upgraded rebar, caught a compromised panel gasket during rough-in, and passed County final inspection without a correction notice.
It will stress an improperly sealed or under-spec’d unit. Home Gardens regularly sees 100°F+ days with low humidity and limited shade. We specify radiant barriers, proper insulation, and right-sized mini-splits as baseline design elements, not upgrades. A compromised envelope seal - common after tight-lot craning - turns summer heat into an infiltration problem that overworks the mechanical system and spikes utility bills.
Often yes. Many Home Gardens homes still have 100-amp panels from the original construction. Dvele’s electrical chase assumes adequate service capacity. During our site visit, we verify panel amperage, load calculations, and grounding compliance to County standards. Panel upgrades run $4,500-$8,500 and we include them in the written quote when required - no surprise additions after work starts. Call (951) 476-3715 for a free assessment of your existing service.
County plan-check for unincorporated ADUs typically takes 4-6 weeks for a complete submittal, longer if corrections are required. We front-load this by building County-specific documentation into the Dvele permit package before submission - addressing setback definitions, owner-occupancy declarations, and utility-connection standards that differ from incorporated cities. Module fabrication runs parallel to plan-check once we confirm approval trajectory. Total timeline from contract to certificate of occupancy typically runs 6-9 months for a LUMO-series installation with standard site conditions.
