Dvele Home Addition Contractor in Los Angeles: What to Know First
We provide independent Dvele home addition contractor work in Los Angeles, and most projects run from initial site assessment to written scope in about a week. A Dvele addition in Los Angeles typically costs between $85,000 and $240,000 depending on size, site conditions, and whether you’re extending from an existing Dvele module or building a complementary structure. We give a written price before any work starts, always, and that number doesn’t change at the door.
This page is for Los Angeles homeowners who already own a Dvele home or ADU and need to add square footage, a second story, a bump-out, or a sunroom, and who want a contractor that actually understands how Dvele modules are assembled. Call (254) 602-5618 to schedule a free site assessment. We’re an independent Dvele service provider, not affiliated with or authorized by Dvele, and that independence means we answer to you, not the manufacturer.
How Dvele Products Fail – and How We Fix Them
Dvele builds high-performance prefabricated homes and ADUs with a steel chassis, dense insulation, and tight air sealing. That’s genuinely good engineering, but it creates specific challenges when you’re adding onto one. Here’s what we actually see on Los Angeles job sites:
- Steel chassis connection points corroding at coastal exposures. Dvele’s platform rests on a steel frame bolted to the foundation. In Los Angeles neighborhoods within about three miles of the coast, marine air accelerates corrosion at those bolt points. By the time an addition is underway, we’re often re-torquing or replacing anchor hardware before framing can begin. We spec galvanized or stainless fasteners on every coastal Dvele job, and we document each connection before we touch anything.
- Wall panel deflection at module seams. Dvele panels are factory-fabricated and joined on site. Over time, especially on Los Angeles hillside lots with minor soil movement, the seam between modules can open by a few millimeters. A homeowner notices the drywall crack but doesn’t know it traces back to a seam, not settlement. For a bump-out or second-story addition, we address the seam before attaching new framing so the addition doesn’t carry the old problem with it.
- Electrical rough-in that doesn’t match local Los Angeles code for additions. Dvele pre-wires for its own systems, but an addition pulls a new permit and triggers inspection under the latest California Electrical Code. We’ve walked onto Los Angeles jobs where a Dvele panel was perfectly fine for the original build but lacked capacity or the right breaker layout for added circuits. That means either a subpanel or service upgrade before the addition is energized. We’ll tell you upfront if that’s coming, because surprises during rough inspection are the expensive kind.
- Roof membrane transitions that weren’t designed for retrofits. Dvele roofs are flat or low-slope with a factory membrane. Cutting into that membrane to tie a second-story addition or sunroom roof is delicate. Done wrong, water intrusion starts where old meets new, and Los Angeles winter rain finds it. We use compatible TPO or PVC seam welding and flash the transition as a single assembly, then water-test it before we close anything up.
- Bathroom addition plumbing tied to Dvele’s compact chase. Dvele homes route plumbing through a vertically stacked wet wall to conserve space. Adding a bathroom several feet away means either running a new waste line through the floor system or tying into the existing stack. The stack might not have the fall for a long lateral run, especially on flat Los Angeles lots. We map the existing plumbing before quoting so we know whether your bathroom addition needs a macerating pump, a relocated stack tie-in, or a re-route, and we price that honestly from day one.
Our Dvele Home Addition Contractor Process
Every Dvele addition in Los Angeles follows the same path, and you’ll know where the project stands at each step. Here’s how it goes:
- 1
Call and site assessment. You call (254) 602-5618, a live person answers, and we schedule a walkthrough at your Los Angeles property. Russ Delmar or a senior project lead walks the lot with you, confirms what the existing Dvele structure is doing, and measures for utility runs, setbacks, and zoning constraints.
- 2
Written scope and price. Within about a week, you get a written line-item price for the addition. Not an estimate, not a range with an asterisk. A number. If something about the permitting process in Los Angeles looks genuinely frustrating, we’ll say so here, then explain exactly how we handle it.
- 3
Permits and drawings. We pull Los Angeles Department of Building and Safety permits for the addition. For a Dvele-module extension, that means structural calcs tied to the existing steel chassis and the new foundation work. We submit, track, and meet inspectors so you don’t have to.
- 4
Build and integreate. We demo only what needs to go, protect the existing Dvele envelope from weather the entire time, and frame, rough-in, and finish the addition while matching the module seam lines wherever possible.
- 5
Test and clean. Before final inspection, we water-test roof transitions, verify all new electrical circuits, and test HVAC flow into the new space. Then the crew cleans up, full stop. The Kingswell Way means leaving the job site cleaner than we found it, and that’s not a slogan, it’s how every Las Angeles project ends.
- 6
Written guarantee. You get a written guarantee on the entire addition before we hand over the keys, not after. If the work fails within the 365-day Done Right Promise period, we come back and make it right, free of charge.

What moves the price in Los Angeles: seismic retrofit requirements on the existing structure, hillside foundation work, Los Angeles Department of Building and Safety plan-check timelines, and whether your Dvele electrical panel needs an upgrade to carry the added load. We’ll tell you which of these apply to your site before we quote. Call (254) 602-5618 to get your written price.

FAQs
It can, depending on what you touch and how. Work that penetrates the original Dvele envelope, roof membrane, or structural chassis may fall outside the manufacturer’s coverage if not handled correctly. As an independent Dvele service provider, we document every connection point and use compatible materials so your addition doesn’t inadvertently kill coverage on the rest of the structure. We’ll tell you exactly which areas of the existing home are affected before work begins. Call (254) 602-5618 and we’ll walk your specific warranty terms with you.
Most Dvele additions in Los Angeles run 3 to 6 months from permit submittal to final inspection, with the actual construction phase typically 8 to 14 weeks. The Los Angeles Department of Building and Safety plan-check step is usually the biggest variable, and we submit complete drawings the first time to avoid correction cycles.
Dvele’s exterior cladding is factory-applied, so matching it perfectly on site is rare. We can usually get close with compatible materials, but if you want a truly seamless look, the more practical route is often a complementary finish rather than a match. We’ll show you both options with actual material samples before you decide.
Yes. If our site assessment uncovers a Dvele module seam issue, chassis corrosion, or roof membrane problem that needs attention before your addition can go in, we can scope and fix that as part of the broader project. You get one contractor, one written price, and one guarantee covering the whole job.
No. The written price we give you before work starts is the price. If Los Angeles inspectors find something we didn’t scope, that’s on us, not on you, unless you ask us to add scope mid-project. Any change order gets its own written price and your approval before we proceed. That’s the Kingswell Guarantee, and it applies to every Dvele addition we build in Los Angeles.
