Dvele ADU in North Tustin, CA | Foundry ADU Builders
We provide independent Dvele service in Orange County’s North Tustin area, from site assessment and County permitting through foundation, crane-set delivery, and finish work. The thing that makes our Dvele work different here is jurisdiction: North Tustin is unincorporated County of Orange land, so the rules are not the same as a City of Tustin ADU. If you’re planning a Dvele unit on one of these estate lots, call (866) 251-7857 for a free site assessment before you spend another dollar on plans.
We work with Dvele units because their panelized wall and floor systems and factory-set utility chases are genuinely well built. But we’re independent. We are not authorized, sponsored, or warranty-endorsed by Dvele. That independence matters: when the factory assumption doesn’t match the North Tustin lot, we’ll tell you plainly and fix it rather than shrug and set the module anyway.
Why North Tustin Residents Choose Us for Dvele Service
Rob Cafferty, our owner, spent his early years in Olinda Village in Brea watching half the neighborhood garages become apartments, studios, and workshops. That was decent training for ADU work. He later went through the Building Technology program at Fullerton College and worked every phase of residential construction before narrowing the focus to ADUs. For the better part of a decade, he’s done exactly that in North Orange County, including Dvele service in Santa Ana and more than a few North Tustin properties with wells, septic fields, and slopes the neighbors don’t have to think about.
We approach Dvele service from the builder side, not the manufacturer side. That means we know where Dvele’s factory rough-ins land, how the modules ride on a crane, and what the panelized shell needs underneath it to stay square. It also means when something on a Dvele unit conflicts with a North Tustin septic setback or a private-well separation, we catch it at the site assessment rather than at the permit counter.

Common Dvele ADU Problems We Solve in North Tustin
Dvele units are well designed, but they’re factory built for general California conditions, and North Tustin’s combination of unincorporated county rules, large lots, septic systems, and inland foothill heat creates specific pressure points. These are the ones we see most often.
- Factory rough-in conflicts with septic and well setbacks. Dvele modules arrive as a single crane-set box with a pre-set plumbing and electrical chase. On North Tustin lots with septic fields and private wells, the County’s required separation distances often push the pad location farther from the house than the factory assumed. The rough-in has to be re-routed before setting, and that’s work best planned before the module is ordered.
- Crane access blocked by the lot layout. Dvele’s module footprint assumes clear rigging space. North Tustin is full of acre properties with horse arenas, detached garages, pools, and mature oaks. The swing radius and utility-clear path the factory set expects often don’t exist. We’ve re-sited more than one Dvele unit because the original pad location would have required removing a tree nobody wanted to lose.
- Cooling loads tuned to the coast, not the foothills. Factory-set Title 24 packages and cooling assumptions calibrated for coastal California underperform below the Santa Ana Mountains. North Tustin runs hotter and drier than the beach cities, and Santa Ana wind events drive window loads hard. Dvele units without added shading or upgraded mechanicals cycle constantly in summer.
- Foundation prep on sloped foothill lots. Panelized Dvele shells need a level, properly engineered foundation. On the sloped canyon-adjacent lots in North Tustin, undersized grading and drainage prep leads to settling and door and window racking within a few seasons. We insist on drainage and pad work before the shell goes up.
- Older electrical panels and private utilities. Many North Tustin homes date from the 1950s to 1970s and run original or undersized panels, private wells, and sometimes shared laterals. A Dvele ADU adds load and plumbing demand. We’re honest when an upgraded panel or new lateral is the smarter spend than working around what’s there.
Dvele Service in North Tustin: What Local Conditions Mean for Your Equipment
Here’s the fact most North Tustin homeowners learn the hard way: this is unincorporated County of Orange land, not the City of Tustin. The setback and lot-coverage standards, the septic and private-well separation distances, the fire-wise and defensible-space requirements near the canyons and open space, all land under County rules. A homeowner on an acre-plus horse property off Newport Avenue was ready to order a Dvele in Villa Park-adjacent North Tustin based on City of Tustin setback numbers. Our site assessment flagged that the lot is County land, that the proposed pad overlapped the septic field separation, and that the sloped rear yard needed drainage work before any crane could reach it. We re-sited the module, coordinated the grading and drainage, pulled the County permit, and set the Dvele unit on an engineered foundation clear of the well and septic lines. That’s the difference between a plan that works on paper and a unit that’s actually permitted and set. Every Dvele project in North Tustin starts with confirming jurisdiction, because getting that wrong costs permits, time, and crane re-mobilization fees.
Rob’s approach on these lots is the same every time: “Figure out what the lot will actually allow, then build the best version of that.” That applies to Dvele specifically because the module dimensions, crane swing requirements, and utility rough-ins are all fixed before the unit arrives. The lot tells you what it can take. Our job is to listen.
Dvele Models & Products We Service in North Tustin
We service the Dvele line as it actually shows up on North Tustin lots. That includes the factory-built single-story modular ADU delivered and set on a county-permitted permanent foundation, the detached prefab panelized shell for backyard builds, attached or interior ADU conversions of existing garage or bonus space, and the two-bedroom Dvele module sized to a half-acre-plus lot. On the repair side, we specify Dvele’s factory components and connection details where they exist. Where the factory has no part available or the lead time would stall a permit-to-delivery schedule, we source vetted equivalent hardware, fasteners, and mechanical components and tell you exactly what we’re using and why. On older North Tustin properties, we’re often the ones telling you an upgraded electrical panel or a new plumbing lateral beats patching around the original.
Dvele Service Pricing in North Tustin
The honest answer is that North Tustin pricing depends on what your site assessment turns up. A flat, city-lot-sized Dvele set on a simple pad is one number. A sloped, septic-served horse property with crane access issues, drainage work, and a panel upgrade is another. The variables that move the number most are site grading and drainage, septic or well separation work, any electrical service upgrade, and crane access complexity. Our free estimate includes a site walk, a jurisdiction check, and a written line-item scope so you can see exactly what’s included and what isn’t.

FAQs – Dvele ADU in North Tustin
County of Orange rules. North Tustin is unincorporated county land, so the County’s setback, lot-coverage, septic, and private-well separation standards govern your Dvele build, not the City of Tustin ordinance. We verify jurisdiction as the first step of every site assessment. Call (866) 251-7857 and we’ll confirm which rules apply to your exact parcel.
Usually yes, but the crane access has to be planned, not assumed. Dvele modules arrive as a single box set by crane, and the factory footprint expects clear rigging space. On acre-plus horse properties with arenas, detached garages, and mature oaks, the swing radius and utility clearances often don’t match the factory set. We do a crane-access review as part of the site assessment and re-site the pad if needed.
It depends on the factory tune and what you add. Dvele’s standard cooling loads and Title 24 packages are set for broader California conditions, and North Tustin’s inland foothill heat plus wind-driven window loads can push a stock unit to cycle hard. We typically add shading elements, window treatments, or upgraded mechanical equipment on canyon-adjacent and south-facing lots. The fix is straightforward if you plan for it before the unit is ordered.
The County will need to see a service that supports the added load, plus water and sewer or septic arrangements that meet separation distances for the new dwelling unit. On older North Tustin properties, that often means an upgraded panel, a new or upgraded lateral, or septic field evaluation before the Dvele pad can be permitted. We don’t patch around outdated infrastructure; we tell you what the County will actually require and quote it in the scope. Call (866) 251-7857 for a free assessment of what your property will need.
It depends on the system’s capacity, the County’s required separation distances, and where the existing field sits relative to your proposed Dvele location. We’ve seen North Tustin septic fields that were sized for the original house and can handle one more bedroom, and others that need a new field or a connection to a shared lateral. We don’t know which yours is until we look. Estimates are free, and the answer changes the site plan, so call (866) 251-7857 before you commit to a pad location.
