Cover Garage Conversion Contractor in San Diego: What to Know First
A Cover garage conversion in San Diego typically runs $145,000 to $210,000 when you’re working with the factory panel system, and most builds take 5 to 8 months from first permit filing to final inspection. We’re an independent Cover service provider, not a factory-authorized installer, which means we give you straight pricing on the conversion work itself without the showroom markup. If you’re a Cover owner trying to figure out whether your existing garage can become a permitted ADU, or you’re mid-build and the original contractor stopped answering, this page tells you what actually happens next. Call (619) 376-2760 and you’ll get a live person, not a menu tree.
How Cover Products Fail – and How We Fix Them
Cover’s panelized building system is genuinely well-engineered, but garage conversions on existing Cover structures hit predictable snags. Here’s what we run into across San Diego, from North Park to Clairemont:
- Cover Series 1 (original panel system) slab-to-wall connection settling. The Series 1 aluminum frame was designed to sit on a poured slab with a specific anchor pattern. On San Diego’s older garage slabs, especially in Mission Hills and Normal Heights where slabs were poured in the 1940s and 50s, the anchors get loose as the slab shifts. The wall doesn’t fall over, but you’ll see drywall cracks at the corners and a door that won’t latch in the wet months. We pull the base trim, re-torque or replace the anchors, and install a compressible seal before we frame anything interior.
- Cover Series 2 wall-panel gasket compression loss. Series 2 panels rely on interlocking gaskets to seal. After five or six San Diego summers, those gaskets dry out and the panels lose their compression. The first sign is a musty smell behind the kitchenette or a faint whistle during Santa Ana winds. Standard contractors will caulk the outside and call it done, but that fails within a season. We cut the old gaskets out, reset the panel gap, and run a compression test with a smoke pencil before the new gaskets go in.
- Undersized electrical rough-in for conversion layouts. Cover garage shells come with a modest panel, usually a 60-amp subfeed. A garage conversion with a mini-split, induction cooktop, and a washer-dryer stack will trip that panel in a week. This is the most common surprise on Cover builds in San Diego, because the shell is fine, but the electrical was sized for a garage, not a dwelling. We pull the load calc, upgrade the subfeed to 100 or 125 amps, and pull the permit before touching the panel.
- Roof flashing mismatch at the conversion tie-in. Where an existing Cover garage roof meets a house wall, the original flashing was often done by the shell installer, not a roofer. After two or three rainy seasons in San Diego, that seam leaks, and the water travels down the Cover wall channels into the slab. Owners see wet drywall at the base of the conversion wall and blame the shell. The real cause is usually eight feet up. We strip back the first two feet of roofing, install step flashing into the house wall, and re-secure the Cover roof panels to the new flashing.
- Cover garage door opening lintel problems when converting to a fixed wall. The factory garage opening is framed for a roll-up door with a thin steel header. When you infill that opening with a window or solid wall, that header is not rated for the new wall load plus a headed window. A conversion done without addressing this will show a sagging header line inside twelve months. We install a proper engineered header, usually an LVL or steel beam depending on the span, and get it signed off by a San Diego structural engineer before drywall.
Our Cover Garage Conversion Contractor Process
Every Cover conversion we run in San Diego goes through the same sequence. No shortcuts, no “we’ll fix it later.”
- 1
Site walk and honesty check. Russ Delmar or our lead walks the garage with you. We look at the slab, the Cover panel condition, the electrical, the drainage, and the property’s setback. You get a written condition report before anyone mentions a price.
- 2
Written price with real line items. We don’t do verbal ballparks. You get a line-item price for every phase: structural, electrical, plumbing, insulation, drywall, finishes, and the permit package. That number doesn’t change unless you change the scope. No price changes at the door, ever.
- 3
Permit package and city submittal. We draw or coordinate the plans, do the Title 24 energy calc, and submit to the City of San Diego Development Services Department. We pull the permit and we’re on site for the inspections. If an inspector flags something, we fix it and get it re-inspected.
- 4
Structural and shell work first. If the Cover shell needs anchor repairs, gasket replacement, or a new header, that happens before any cosmetic work. We will not bury a known shell problem behind drywall.
- 5
MEP rough-in and inspection. Plumbing, electrical, HVAC. We schedule the rough inspection, pass it, and only then insulate and close walls.
- 6
Finish work, final inspection, cleanup. Trim, paint, flooring, fixtures. We walk the unit with you, write down anything you flag, fix it, then call for the final inspection. After the city signs off, we run a cleaning pass and hand you the keys and your written 365-Day Done Right Promise.
What Cover Garage Conversion Contractor Costs in San Diego

Here’s what we’re actually seeing on Cover conversions in San Diego in 2026, depending on condition and scope.
- Basic conversion, good slab, no shell repairs: $145,000 – $165,000.
- Conversion with electrical panel upgrade and minor shell repairs: $170,000 – $195,000.
- Full gut with header replacement, gasket work, new subfeed, and finish-level buildout: $195,000 – $240,000.
- Add a detached Cover unit or major site work (drainage, retaining walls): $240,000 and up, honestly priced after the site walk.
What moves the price: the age of your Cover shell, the condition of the garage slab, the distance from your existing sewer line, and whether the city makes you do a full stormwater plan. Older San Diego neighborhoods with narrow lots and hillside drainage add real cost. We’ll tell you all of this before you sign anything, and the estimate is free. Call (619) 376-2760 and we’ll schedule the walk.
Why San Diego Homeowners Call Lodgewick ADU San Diego for Cover Work
We work on Cover panels because the factory did good work, and we respect the system. We also know where it fails in San Diego’s climate, which is the part the brochure doesn’t mention. Our crew has hands-on experience with Abodu and Dvele as well, so when a homeowner asks whether fixing a Cover shell is smarter than bringing in a different prefab system, we can speak from experience, not from a sales deck. The Kingswell Guarantee means a written price before we start, a real arrival window, a clean site at the end of every day, and a written guarantee on every build. If something isn’t right within 365 days, we come back and make it right, in writing, free. That’s the whole deal. Tell me what you’re hoping to build, and I’ll tell you what it actually takes, cost, timeline, and all the permit steps, before you spend a dime.
FAQs

Yes, in most cases. The Cover shell itself is not automatically permitted as a dwelling, so the conversion requires a new permit package through the City of San Diego, including structural review of the slab and panel connections, electrical, plumbing, and Title 24 energy compliance. We handle the full package. Call (619) 376-2760 and we’ll tell you whether your specific garage is a candidate after a site walk.
A garage-to-ADU conversion changes the structure and the use, which can affect your original Cover shell warranty. Because we’re an independent Cover service provider, we document every structural change and use Cover-compatible parts and methods where the shell remains intact. We can’t speak for Cover’s warranty department, but we can give you a written record of everything we do. Call (619) 376-2760 if you want us to walk through your specific shell condition first.
Most Cover garage conversions in San Diego take 5 to 8 months from permit submittal to final inspection. The longest wait is usually the city’s plan review, not the construction. We give you a written schedule with real dates before work starts, and we keep you posted on every inspection. Call (619) 376-2760 for a timeline specific to your street.
Yes, and this is a big part of our San Diego work. We see abandoned Cover conversions where the slab was poured, the shell panels went up, and the contractor disappeared when the permit got complicated. We step in, pull the existing file, re-permit what needs re-permitting, and finish the job properly. You get the same written price and the same 365-Day Done Right Promise as a fresh build. Call (619) 376-2760 and we’ll come look at what’s there.
No. The price we give you in writing is the price you pay, unless you ask us to change the scope. If we find something unexpected inside a wall, we stop, show you what we found, give you the cost to address it in writing, and wait for your approval. We don’t run change orders without your signature. That’s the Kingswell Way, and it’s in writing on every Lodgewick ADU San Diego project. Call (619) 376-2760 to get your starting number.
