Dvele ADU in San Francisco, CA | Lodgewick ADU San Francisco
We service and repair Dvele factory-built ADUs throughout San Francisco, and we do it as an independent provider, not a manufacturer affiliate. The thing that sets our Dvele work apart here is that we know what the city’s seismic retrofit mandates and coastal zone rules do to these panelized systems over time. If your DveleIQ or DveleAire unit needs attention, call (707) 760-0502 and you’ll get Russ Delmar or a member of our crew on the line, not a call center.
Why San Francisco Residents Choose Us for Dvele Service

Dvele builds a genuinely well-engineered ADU. The factory panel system, the integrated smart home controls, the steel-frame LGS models, all of it is designed and built with a level of precision most site-built framing never approaches. But a Dvele ADU still has to survive San Francisco’s particular conditions: fog that never fully burns off in the Sunset, Victorian-era lot lines that squeeze a unit against a neighbor’s wall, and a Department of Building Inspection that wants to see documentation for every modification.
We’re the crew that handles the gap between what the factory shipped and what San Francisco will sign off on. Russ Delmar studied construction technology at LA Trade-Tech and spent years on foundation and finish carpentry crews before ADUs became his focus. He’s been working Dvele systems across San Francisco for the better part of a decade, including projects within a few blocks of Dolores Park where the lot lines alone make every build its own puzzle. Our Dvele sales & service work covers everything from initial install support to warranty-adjacent repairs, and we carry OEM-compatible sealing systems and moisture barriers on our trucks so a fog-belt service call doesn’t stall waiting on a shipping label.
We’re licensed, insured, and every job comes with our 365-Day Done Right Promise in writing before we start. That means if a repair fails within a year, we come back and make it right, no invoice.
Common Dvele ADU Problems We Solve in San Francisco
- Moisture intrusion at panel seams on DveleIQ units. In fog-belt neighborhoods like the Sunset and Richmond, marine air pushes condensation behind the exterior cladding. We find moisture readings over 20% behind lower wall panels on a regular basis. The fix usually involves removing the affected cladding, replacing any delaminated panels, and re-sealing with marine-grade butyl tape, not the standard flashing tape the factory sends.
- Foundation settlement on DveleAire LGS units. Where these units sit on San Francisco’s sandy dune soils without adequate pier depth, floors go out of level and interior doors start to bind. The western neighborhoods are the worst for this. We address it by shimming and correcting the pier supports under the steel frame, then checking the panel alignment before the cracks telegraph through the walls.
- Condensation on factory ducting in basement ADU conversions. Many San Francisco basements hold humidity year-round, even with a heat recovery ventilator running. Mildew smells from the duct runs are a common call in Noe Valley and Glen Park where Victorian basements never fully dry out. We supplement with additional ERV ducting and moisture barriers in the crawlspace.
- Electrical panel conflicts with older homes. Dvele’s integrated 200A service doesn’t play well with the 60-100A legacy panels still common in pre-war San Francisco housing stock. When the permit reviewer flags it, we handle the rewiring mandate and coordinate the DBI inspection.
- Window frame corrosion near the coast. In the Outer Sunset and Outer Richmond, salt-laden fog accelerates corrosion on Dvele window frames. If the frames are beyond sealing, we recommend panel replacement over patchwork, because another wet winter will undo a quick fix.
Dvele Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s something most Dvele owners don’t hear until they’re deep into a permit review: if your property sits within San Francisco’s Local Coastal Program overlay, which covers neighborhoods like the Outer Sunset, your Dvele ADU has to pass a coastal zone consistency review on top of the city’s base ADU ordinance. That review imposes stricter exterior material and height limits than what the factory’s standard panel finishes are designed around. We’ve seen site-specific revisions required on panel colors, cladding materials, and roof profiles that the Dvele catalog doesn’t mention anywhere. Our San Francisco service area work includes helping owners navigate that consistency review, because getting the exterior details right the first time saves you a rejected permit and a six-week delay. On 46th Avenue near Ortega, we installed a DveleIQ LGS one-bedroom over a converted garage where the floor had to be raised 18 inches above the FEMA floodplain. During the first fog season, our moisture meter found 22% moisture content behind the lower cladding. We re-sealed the panel joints with marine-grade butyl tape, replaced two delaminated wall panels, and added a supplemental ERV duct to the crawlspace. The unit passed its DBI final inspection the following spring.
Dvele Models & Products We Service in San Francisco
We service the full Dvele lineup: DveleIQ, DveleAire, DveleIQ LGS, and DveleAire LGS. Our parts approach is straightforward. For structural and envelope components, we default to Dvele OEM sealed assemblies so the factory weatherproofing and seismic rating stay intact. For breakers, ducting, and moisture barriers, we use locally sourced UL-listed parts when OEM lead times would delay a permit inspection. A Dvele wall panel that’s delaminating or a window frame corroded beyond sealing gets replaced, not patched, because San Francisco’s wet winters punish half-measures.
Dvele Service Pricing in San Francisco
Most Dvele repair calls in San Francisco fall between $300 and $900 depending on scope. A panel seam re-seal is usually on the lower end. A full panel replacement with crane or lift access can push past $3,000. Foundation leveling on a settling DveleAire LGS unit typically runs $1,200 to $4,500 depending on how many piers need correction. We give you a written price before any work starts, and that number doesn’t change at the door. Call (707) 760-0502 to schedule a free estimate and we’ll walk the site before we quote anything.

FAQs – Dvele ADU in San Francisco
No. San Francisco’s hillside lots, common in neighborhoods like Twin Peaks and Forest Hill, require a geotechnical report before DBI will issue a permit for a DveleIQ ADU. The foundation design has to address slope stability and seismic load, and Dvele’s factory foundation specs don’t override that local requirement. Call (707) 760-0502 and we’ll walk you through what the report needs to cover for your specific lot.
Every new ADU in San Francisco, including a DveleAire basement conversion handled by our Garage Conversion Contractor in San Francisco, must include a fire sprinkler system tied to the main water service. If your home’s existing water line is undersized, which is common in pre-war buildings, you’ll need a service upgrade before the DBI inspection. We coordinate that work as part of the build. For an exact scope and price, call (707) 760-0502.
Mostly, yes. Dvele’s factory-built systems are designed around California’s Title 24 energy standards, which San Francisco adopts. But the city’s local green building ordinance has a few additional requirements around construction waste diversion and indoor air quality that may need documentation or minor field adjustments, especially on basement conversions. We handle those adjustments during install or service.
San Francisco’s ADU ordinance requires the city to review ADU permit applications within 120 days, and the city has made real progress on streamlining. But that clock pauses every time a plan reviewer requests a revision. Dvele’s permit-ready drawings still get sent back when local conditions like coastal zone review or seismic retrofit details aren’t addressed. We’ve helped enough owners through that loop to know where the friction points are. Call (707) 760-0502 and we’ll take a look at your plans before you resubmit.
Moisture intrusion at the panel seams on DveleIQ models. The persistent marine layer in the Sunset and Richmond drives condensation behind the cladding, and we find elevated moisture readings on most first-year service visits. The fix is a re-seal with marine-grade butyl tape and, in severe cases, panel replacement. If you’re noticing musty smells or bubbling paint on your Dvele walls, call (707) 760-0502 for an estimate, and we’ll get a moisture meter on it.
