Dvele Home Addition Contractor in San Diego: What to Know First
We’re an independent Dvele service provider in San Diego, and we handle home additions on existing Dvele homes, including room additions, bump-outs, and garage expansions. Typical Dvele addition work in San Diego runs $185 – $310 per square foot for permitted construction, depending on site access, foundation conditions, and whether we’re tying into the existing steel chassis or doing slab work. Most Dvele addition projects take 8 – 16 weeks from permit submittal to final inspection. We’re not affiliated with Dvele, and we’re upfront about what their factory tolerances mean when you’re cutting into a factory-built panel system.
This page is for San Diego homeowners who own a Dvele home and need an addition contractor who understands how these buildings are actually put together, and what changes when you’re joining new framing to a prefabricated steel-and-panel envelope. Call (619) 376-2760 and we’ll walk your site, look at your existing Dvele build, and give you a written cost range before you commit to anything.
How Dvele Products Fail, and How We Fix Them
Dvele builds a tight, efficient envelope. That’s the good news. The hard part with additions is that the factory precision doesn’t automatically extend to site-built framing, and the failure points we see on Dvele additions in San Diego are consistent. Here’s what we handle most often:
- Chassis tie-in leaks at the roofline, common on the Dvele IQ line. Dvele’s factory roof assembly is sealed and tested at the plant. When a San Diego contractor adds a site-built room, the junction between the existing steel roof panel and the new stick-framed roof is the first place water finds its way in. We over-flash that junction and lap the Dvele panel with a soldered metal transition rather than relying on peel-and-stick alone, which is what most addition crews do and why those junctions leak within two winters.
- Panel shear tolerance issues when cutting new door openings, seen on Dvele’s steel-framed wall modules. Dvele wall panels carry structural load through the steel frame, not through conventional studs. Cutting a wide opening for a new hallway into an addition without checking the panel’s shear diagram means the wall can rack over time, and you’ll see hairline cracks where drywall meets the ceiling. We review the Dvele as-built drawings before we touch a saw, and we frame the opening with a steel header that matches the panel’s load path instead of guessing with lumber.
- Floor level mismatch between the original Dvele module and the site-built addition, especially on sloped San Diego lots. Dvele sets their modules on a foundation they spec for the factory floor tolerance. When a new addition’s slab or crawlspace floor is poured even three-quarters of an inch higher or lower than the Dvele floor, you feel a step, and your doors at the transition bind within a year. In neighborhoods like Clairemont and Mission Hills where lots slope, we shoot the existing Dvele floor elevation with a laser before designing the addition foundation, and we match it within an eighth of an inch.
- HVAC integration problems, particularly with Dvele’s ERV system. Dvele homes have a balanced ventilation strategy built into the original envelope. A site-built addition almost always changes the load calculation, and if the new space just gets a duct tied into the existing ERV, the whole house’s indoor air quality drops. We recalculate the entire envelope’s cubic feet per minute on every San Diego Dvele addition and recommend an ERV upgrade or a dedicated mini-split when the original unit can’t handle the added square footage.
- Stucco and cladding mismatch at the addition seam, common on Dvele’s exterior finish system. Dvele’s exterior panels have a specific reveal and texture. Matching stucco color and texture on a San Diego addition is doable, but the seam will show if you don’t control the curing rate, especially in the dry East County heat. We use a fog-cure process and match the Dvele finish sample under daylight, not just under shop lights, before we call the exterior done.
Our Dvele Home Addition Contractor Process
Russ Delmar and our crew have worked on enough Dvele additions across San Diego to know that these jobs go sideways when someone treats the home like any other stick-built house. They’re not. Here’s how we run a Dvele addition from first call to final walkthrough:
- 1
Site walk and as-built review. We walk the home, pull measurements, and if you have the original Dvele construction documents, we review them before we write anything down. If you don’t have them, we still map the existing panel layout on-site.
- 2
Written scope and cost range. We give you a line-item written price before work starts. No change orders at the door. That’s The Kingswell Guarantee, and it applies to Dvele additions the same as every other job.
- 3
Permit drawings and city submittal. We prepare the plans and submit them to the City of San Diego or the County if you’re in an unincorporated area. We pull the permit, and we stay on the job until the inspector signs off.
- 4
The build. Background-checked, uniformed crew on-site. We protect the existing Dvele envelope with dust barriers and floor protection before we cut any openings. The job site gets cleaned at the end of every day.
- 5
Inspection and sign-off. We schedule the city inspection, walk it with the inspector, and fix anything flagged before you get the final sign-off.
- 6
Written guarantee. Your Dvele addition carries our 365-Day Done Right Promise in writing. If something isn’t right within a year, we come back and make it right. Free return visit within the guarantee period.
What Dvele Home Addition Contractor Costs in San Diego
Here are real numbers for Dvele addition work in San Diego, based on jobs we’ve done in the last few years. These are ballpark ranges, not quotes. Your lot, your existing Dvele model, and the scope of your addition move the final number.
- Dvele room addition, 200 – 300 sq ft: $37,000 – $93,000, permits included, based on $185 – $310 per square foot. Smaller additions cost more per square foot because mobilization and permit costs are fixed.
- Bump-out addition, 80 – 150 sq ft, on an existing Dvele wall: $22,000 – $48,000. Cutting into the steel panel and re-flashing the roofline drives much of this cost.
- Second-story addition on a Dvele, 400 – 700 sq ft: $112,000 – $217,000. Structural steel to carry the new floor over the existing Dvele roof is the biggest line item.
- Garage addition or garage conversion tied to the Dvele home: $28,000 – $85,000, depending on whether it’s attached or detached and whether the existing garage shares a wall with the Dvele module.
What moves the price most: whether we’re cutting into the existing Dvele envelope or building standalone, the foundation type your San Diego lot requires, and whether your Dvele ERV needs an upgrade to handle the added square footage. Call (619) 376-2760 and we’ll give you a written range after a site walk. Estimates are free.

FAQs
Yes. We’re an independent Dvele service provider, not an authorized Dvele contractor, so our work does not void or alter your factory warranty. We document everything we do and provide photos and written scope notes if you need to communicate with Dvele about a warranty claim. Where our addition work touches the original Dvele envelope, we use methods that preserve the integrity of the factory assembly. Call (619) 376-2760 if you want to talk through what an addition means for your warranty situation.
Yes, we match the Dvele stucco texture and color on-site, and we fog-cure the new stucco in dry San Diego heat so the texture and color don’t telegraph the seam. It won’t be invisible, but it’ll be close enough that most people won’t notice unless they’re looking for it. We’ll show you finish samples in daylight before we apply anything.
Most of our San Diego Dvele additions run 8 – 16 weeks from permit submittal to final inspection. Permitting with the City of San Diego usually takes 3 – 6 weeks for a straightforward addition, and the actual construction on a 200 – 300 square foot room addition is typically 6 – 10 weeks. Bigger second-story jobs run longer. We’ll give you a written schedule with your estimate.
No. Your Dvele addition gets a written price before any work begins, and we don’t change the price at the door. If we uncover something hidden once we open the wall, we stop, show you what we found, and write a change order for your approval before we proceed. No surprise invoices. That’s The Kingswell Guarantee, and it’s in writing on every project.
Yes. We pull all required permits from the City of San Diego or the County of San Diego, whichever has jurisdiction over your property. We schedule the inspections, walk them with the inspector, and make corrections if anything gets flagged. You get the final sign-off before we call the job complete. Call (619) 376-2760 for a free estimate on your Dvele addition.
