We work on Dvele LUMEN, Solstice, and Q/Core units across Tustin - from Old Town bungalow lots to Tustin Legacy properties - handling site assessment, foundation adaptation, electrical upgrades, and permit resubmittals when factory plans meet local ground conditions.

Why Tustin Residents Choose Us for Dvele Service
We’ve worked on Dvele units in Tustin since the Tustin service area opened up under California’s revised ADU statutes. Nadia Ellery, who leads our studio, spent years in the field before founding Ellery ADU Studio in 2015 - the same year state ADU law shifted - and she still keeps a marked-up copy of the statute on her desk. That background matters when a Dvele unit arrives on a truck and the foundation plan assumes soil conditions that don’t match what’s under a Browning neighborhood lot.
We are not Dvele-authorized. We’re the crew homeowners call after they’ve received a factory quote and need someone to verify whether their Tustin lot can actually support what was promised. Our license number appears on every page, every permit set, and every written scope. We use Dvele OEM structural connectors and envelope tapes where available, and we source code-compliant aftermarket components locally when factory lead times would stall a Tustin permit. Every project gets a written price before work starts, per Haven Standard Clause 1. No exceptions.
Common Dvele ADU Problems We Solve in Tustin
- Panel seam water intrusion under Santa Ana winds. Dvele’s factory-installed ridge caps and panel seams perform well in controlled conditions. On exposed Tustin Legacy lots near West Warner Avenue, those same seams see wind-driven rain at velocities coastal Dvele units never encounter. We reseal with upgraded tapes and add wind-driven-rain baffles where the factory detail falls short.
- Foundation conflicts with remnant MCAS infrastructure. The Dvele pier-and-slab interface assumes uniform, undisturbed soil. In the Tustin Legacy footprint and neighborhoods like Fairbridge Square, we routinely find unmapped 1940s storm drains, non-standard utility easements, and remnant military slab that the factory foundation plan doesn’t account for. We redesign the pier layout and coordinate with the city on revised grading plans.
- Electrical service undersized for all-electric Dvele loads. Old Town Tustin’s 1920s-1950s housing stock often carries 60-amp panels and aluminum branch circuits. A Dvele Solstice with heat-pump HVAC and battery integration won’t run on that. We pull permits for full 200-amp upgrades and coordinate with SCE on service lateral sizing.
- Ember-vent detailing below Tustin fire-hazard standards. Tustin’s inland position means higher fire-hazard zone classifications than coastal neighbors. Some Dvele modules ship with standard soffit vents that aren’t ember-resistant. We upgrade to WUI-compliant vents and roof-edge detailing before final inspection.
- Permit resubmittals after two-track compliance failures. Tustin Legacy homeowners often get caught between unenforceable HOA CC&Rs and the MCAS Tustin Specific Plan’s independent development standards. We’ve taken over stalled projects where the original contractor understood state ADU law but missed the Specific Plan’s setback and lot-coverage overlays.
Before
AfterDvele Service in Tustin: What Local Conditions Mean for Your Equipment
Tustin’s most consequential ADU dynamic sits in the Tustin Legacy specific plan area, built on the former Marine Corps Air Station Tustin footprint. Here’s what actually happens: a homeowner in French Court or French Park receives a Dvele LUMEN quote from the factory, checks their HOA CC&Rs, sees a prohibition on ADUs, and stops. The prohibition is unenforceable under California Civil Code §4751. But that is not the end of the analysis. The MCAS Tustin Specific Plan maintains its own setbacks, lot coverage limits, and height restrictions, entirely separate from the HOA document. A Dvele unit that clears state ADU law can still fail Specific Plan review.
This two-track compliance doesn’t exist in Irvine, Santa Ana, or Orange. For Dvele owners, it means the factory’s standard site plan often needs redesign before Tustin will issue a foundation permit. The Q/Core frame dimensions are fixed. The sitework is not. We’ve redesigned pier layouts for Dvele units on Santiago Street and Tustin Ranch Road where the factory assumed a 20-foot rear setback and the Specific Plan allowed 15, but with a height restriction that forced a lower roofline. The frame ships from the factory. The foundation and utility connections are where Tustin’s local rules rewrite the plan.
In the Browning neighborhood off East Edinger Avenue, we took over a stalled Dvele LUMEN ADU for a homeowner whose original contractor stopped after the permit was kicked back by the city. Our crew located an unmapped 1940s storm drain and remnant MCAS-era slab under the proposed footprint, redesigned the pier layout, pulled the electrical service from 60-amp to 200-amp, and brought the roof-edge vents up to Tustin’s ember-resistant spec - the unit closed final inspection on the resubmittal.
Dvele Models & Products We Service in Tustin
We specify and coordinate Dvele sales & service for three product lines in the Tustin market. The Dvele LUMEN series is a modular prefab ADU with a steel-frame Q/Core structure and high-performance envelope - the line we see most often on Tustin Legacy lots where height limits favor a compact footprint. The Dvele Q/Core building system is the panelized core shared across their ADU and single-family lines; we repair and upgrade Q/Core connections, panel seams, and envelope tapes. The Dvele Solstice series adds solar-plus-battery integration, which in Old Town Tustin almost always requires the electrical panel upgrade we handle in-house.
Our Tustin warehouse stocks Dvele-compatible structural connectors, envelope tapes, and electrical interface kits. When OEM lead times stretch past permit deadlines, we match with code-compliant aftermarket components from Orange County suppliers. The shell is usually worth keeping. The sitework, panel detailing, and utility connections are where we do the actual work.
Dvele Service Pricing in Tustin
Dvele ADU site assessments in Tustin typically run $450-$850, depending on whether we need to locate buried MCAS-era infrastructure or coordinate with the city on Specific Plan overlays. Foundation and grading work for a Dvele unit on a Tustin Legacy lot - including pier redesign, soil remediation, and slab modification - generally falls between $8,500 and $18,000. Electrical panel upgrades from 60-amp to 200-amp service, including permit and SCE coordination, usually range $4,200-$7,800. Full design-build Dvele projects, from site assessment through final inspection, typically start around $145,000 for a Garage Conversion ADU - Tustin and $195,000 for a new detached unit.
These ranges reflect Tustin’s specific conditions: the two-track permit process, the buried infrastructure risk, and the fire-hazard zone requirements that coastal Dvele projects don’t face. Every quote is written, line-itemed, and locked at signing per Haven Standard Clause 1. No change orders. No door-side upsells. Call (949) 541-8498 for your exact numbers - estimates are free.

FAQs - Dvele ADU in Tustin
No. Under California Civil Code §4751, HOA CC&Rs that prohibit ADUs are unenforceable against compliant state ADU projects, including Dvele prefab units. However, the MCAS Tustin Specific Plan’s independent setbacks, lot coverage, and height limits still govern what you can build. We handle both tracks. Call (949) 541-8498 to review your specific lot.
The Dvele unit can sit there, but it won’t run. Dvele’s all-electric heat-pump load requires 200-amp service minimum. We pull permits for the panel upgrade and coordinate with SCE as part of our single-contract scope. Call (949) 541-8498 for a written quote on the full electrical package.
Tustin assessments require utility locating for unmapped MCAS-era infrastructure, Specific Plan overlay review, and fire-hazard zone verification that Irvine projects don’t need. The extra time is documented in your written scope. Call (949) 541-8498 to schedule.
Some Dvele modules ship with standard soffit vents that need upgrading to WUI-compliant ember-resistant specs for Tustin’s inland fire-hazard zones. We handle that upgrade during sitework, before final inspection. Call (949) 541-8498 to verify your unit’s vent package.
We use Dvele OEM structural connectors, envelope tapes, and electrical interface kits where available. When factory lead times would stall a Tustin permit, we match with code-compliant aftermarket components from local suppliers and document the substitution in your permit set. Here is what it costs, here is what you get, here is the document that says so.
