Dvele Garage Conversion Contractor in San Francisco: What to Know First
Converting a Dvele home’s garage into livable space in San Francisco typically runs $180,000 to $320,000 for an attached conversion and $220,000 to $380,000 for a detached build, with most projects taking 5 to 9 months from first walkthrough to final inspection. We’re an independent Dvele service provider – not affiliated with or authorized by Dvele – but our crews work on these homes regularly and know where they hold up and where they fight back. If you own a Dvele in San Francisco and the garage is eating space you could actually live in, call (707) 760-0502 and we’ll walk the site before we quote a number.

How Dvele Products Fail – and How We Fix Them
Dvele homes are panelized and built tight, which is good for energy performance but creates real friction when you’re opening up a garage wall. Here’s what we see on Dvele garage conversions in San Francisco:
- Panel joint separation at the garage-to-living-wall connection. On the Dvele Wave and Dvele Current lines, the SIP (structural insulated panel) joints where the garage abuts conditioned space can separate slightly as the building settles on San Francisco’s clay-heavy hillside soils. We see gaps of 1/8″ to 1/4″ at the top plate. The fix means re-flashing the seam, tightening the mechanical connection, and adding a compressible seal before any drywall goes up.
- Undersized HVAC registers in converted garage bays. Dvele’s standard duct layout assumes the garage stays a garage. When you convert that space, the existing register count and trunk line size often can’t move enough air for a bedroom or living room. We run a Manual J load calculation on every Dvele conversion and typically add 1-2 supply registers plus a return, tied back to the main unit.
- Moisture readings that spike near the slab edge in winter. San Francisco’s fog and winter rains push moisture against the slab edge, and Dvele’s sill plate detail – while code-compliant – can wick in humid months when a garage sits below grade on the uphill side. We check moisture content with a meter before framing. If it reads above 18%, we address drainage and add a capillary break before building.
- Electrical panel capacity that falls short of a true living space. Dvele’s standard 100-amp panel on some earlier Current series homes leaves little room for the added circuits a garage ADU – that’s accessory dwelling unit, meaning a second fully permitted living space on your own property – actually needs: kitchenette, laundry, bathroom, heat pump. We scope the panel upgrade early so it’s priced in writing, not discovered mid-job.
- Exterior wall penetrations that don’t match the Dvele WRB (weather-resistant barrier) detail. When a previous owner or a handyman added a door or vent through a Dvele exterior wall, we often find the WRB was cut back and never re-lapped correctly. That’s a slow leak waiting to happen here in the Marina or the Sunset where wind-driven rain is a regular thing. We cut back to clean sheathing, re-lap the barrier, and re-flash every penetration before closing up the wall.
Our Dvele Garage Conversion Contractor Process
Russ Delmar walks every Dvele job personally before we quote. Here’s how the work goes from first call to final walkthrough:
- 1
Site walk and floor-level check. We inspect the garage slab, measure the existing openings, check panel joint conditions, and note any grading or drainage issues around the perimeter. On Dvele homes, this also means locating the factory-installed chase lines so we know where utilities can run without cutting through structural panels.
- 2
Written scope and fixed price. You get a line-item quote that covers the work we know needs doing, plus a contingency line for what we can’t see until a wall comes open. The price is written before any work starts – every time.
- 3
Permit package and Plan review. For garage conversions in San Francisco, we handle Planning Department ADU review, DBI plan check, and Title 24 energy documentation. Dvele’s panelized construction means the structural calcs sometimes need a third-party letter – we take care of that.
- 4
Demolition, panel work, and rough-in. We remove the garage door and track, frame the new wall, run electrical and plumbing through the existing chases where possible, and install the HVAC runs the space actually needs.
- 5
Finish work and systems test. Drywall, flooring, paint, fixtures. We run the blower door test, check every outlet, run the heat for a full cycle, and walk the job with you before final inspection.
- 6
Written guarantee. Every Dvele garage conversion gets The Kingswell Guarantee in writing: if it’s not done right within 365 days, we come back and make it right – free.

Tell me what the space needs to do, and we’ll figure out how to build it right.
FAQs
It can, depending on which Dvele warranty terms apply to your home. Structural modifications to the original panelized envelope – cutting into SIPs, changing rooflines, moving load-bearing walls – may fall outside the factory warranty, while interior finish work in the garage rarely does. As an independent Dvele service provider, we recommend reviewing your warranty documentation with your builder before we finalize the scope, and we’ll flag any proposed work that crosses into warranty-sensitive territory during the site walk. Call (707) 760-0502 and we’ll walk you through it before anything gets cut.
Most Dvele garage conversions in San Francisco run 5 to 9 months from first walkthrough to final inspection, with permit review typically taking 2 to 4 months of that. The site work itself usually takes 8 to 14 weeks. Dvele panel work, when we’re tying into the existing envelope, can add a week or two because the tolerances are tighter than stick-built framing. We’ll give you a written schedule with your quote, not a verbal estimate.
Yes, and a Dvele home makes that easier than you might expect because the panelized construction holds its thermal performance even after we modify the garage bay. San Francisco allows attached and detached ADUs up to certain size limits depending on your lot, and the permit path is separate from a standard remodel. A garage ADU means a second living space on your existing property – kitchenette, bath, separate entrance – that you can rent or use for family. Call (707) 760-0502 and we’ll check your lot dimensions and zoning before you commit to anything.
An attached Dvele garage shares a wall and often a foundation run with the main structure, so conversion usually means less foundation work and shorter utility runs. A detached garage conversion means running power, water, and sewer separately, and the slab is more likely to need attention if drainage wasn’t set up right initially. In San Francisco, detached garage ADUs often face steeper rear yard and setback reviews at Planning. Both are doable – we’ve done both on Dvele homes – but the price and timeline differ enough that we’ll show you both numbers before you choose.
If anything fails within 365 days of completion, we come back and make it right at no cost – that’s the 365-Day Done Right Promise, and it’s in writing on every project before work begins. You don’t chase anyone, you don’t argue about whether it’s covered, and you don’t wait weeks for a callback. Call (707) 760-0502, talk to a live person, and we schedule the return visit.
Yes. We pull permits for every garage conversion through the San Francisco Department of Building Inspection and coordinate with the Planning Department for ADU review where required. Title 24 energy compliance is part of our scope, and we don’t start work until permits are issued. You get a copy of every permit and every inspection sign-off.
