How Cover Products Fail – and How We Fix Them
Cover builds precision-engineered panelized homes, and their garages follow the same factory-tight approach. That precision creates predictable conversion challenges. Here’s what we see in San Diego, based on the Cover models we work on.
- Cover C-Series attached garages: undersized shear wall blocking. The C-Series is Cover’s attached garage line, and the factory framing is efficient but lean. When we cut into the wall between the garage and the main home for a door opening, the existing shear blocking often doesn’t meet San Diego’s lateral load requirements for converted living space. We add plywood shear panels and hold-down hardware before inspection, which is why our conversions on C-Series homes rarely get red-tagged on the first framing inspection.
- Cover S-Series garage slabs: moisture vapor issues. The S-Series is the larger detached and semi-detached line, often built on slabs poured quickly to keep the factory schedule moving. In San Diego’s coastal zones, especially Point Loma, Ocean Beach, and parts of Pacific Beach, we regularly find elevated moisture readings in those slabs. Before flooring goes down in a garage-to-bedroom conversion, we run calcium chloride tests and install a 10-mil vapor barrier plus a dimple mat where readings are high. Skipping this step on an S-Series slab means buckled LVP within two years.
- Ceiling height compromises in Cover garage trusses. Cover garages use low-profile trusses to match the roofline. When a client wants a vaulted ceiling in the converted space, we don’t just remove the bottom chord. We sister in engineered LVLs sized to San Diego’s wind zone, which keeps the roofline stable while opening the room. On a recent conversion in Kensington, this added two days of framing but kept the exterior profile exactly as Cover designed it.
- Panel seam settling around garage door openings. Cover wall panels are joined at factory seams, and the garage door opening is often a seam location. After a few San Diego summers of thermal expansion, we see hairline cracks running vertically at those seams. Before we frame in the garage door opening with a new wall, we inspect every seam within three feet, re-fasten loose panel connections, and seal with a paintable elastomeric. It prevents those cracks from telegraphing through the new drywall.
- Electrical service sizing on Cover garages. Cover’s standard garage electrical panel is sized for a garage: a door opener, a light, maybe a workbench outlet. Converted living space needs more. We see a lot of Cover homes in Clairemont and North Park where the original 100-amp main panel and 30-amp garage subpanel won’t support a kitchenette plus minisplit plus laundry. We handle the service upgrade as part of the conversion, pulling the SDG&E permit and coordinating the disconnect, so your converted garage doesn’t trip breakers every evening.
Our Cover Garage Conversion Contractor Process
Here’s what a Cover garage conversion looks like with us, step by step:
- 1
Walkthrough and measurements. Ben Ortega or one of our senior leads walks the garage with you. We look at the Cover panel seams, slab condition, truss layout, and the existing electrical. We ask how you’ll actually use the space: bedroom for aging parents, rental ADU, home office with a bathroom.
- 2
Written scope and price. Before any permit is filed, you get a line-item price for the entire conversion. No allowances that drift, no surprise change orders when the slab needs work. The number in writing is the number on the final invoice unless you ask us to add scope.
- 3
Permits and drawings. We pull permits through the City of San Diego or your jurisdiction in the county. For attached garage conversions in San Diego, that means the standard ADU checklist, Title 24 energy compliance, and possibly a fire sprinkler determination if your lot is in a high-density zone. We handle it.
- 4
Construction with the Cedarwell Care Promise. Shoe covers and drop cloths inside your home every visit. Pet-safe products where there’s a choice. Quiet tools near bedrooms and during school hours. A photo of the clean-up before the crew leaves, sent to you the same day.
- 5
Inspection and closeout. We walk the finished space with you before the city inspector does. Every outlet tested, every door squared, the vapor barrier documented. Then we schedule final inspection and stand there with you while it passes.
- 6
365-Day Done Right Promise. If something isn’t done right in the first year, we come back and make it right. No phone-tree arguments, no “that’s normal settling” talk. It’s in writing.
What Cover Garage Conversion Contractor Costs in San Diego
Here are real ranges we’ve quoted on Cover homes in San Diego over the last few years:
- Attached garage to bedroom + bathroom (C-Series): $85,000 to $125,000.
- Attached garage to full ADU with kitchenette (C-Series or S-Series): $110,000 to $150,000.

What moves the price: slab moisture remediation, electrical service upgrades, kitchenette plumbing runs, and whether the existing Cover roof structure needs reinforcement for a ceiling change. The single biggest variable in San Diego is the state of the garage slab. We test every slab during our walkthrough, so we know the real number before you sign anything. Call (858) 988-6447 and we’ll walk your Cover garage and put a written number in your hand.
Why San Diego Homeowners Call Seedling ADU San Diego for Cover Work

Every job gets the same three promises: a written price before a tool is touched, the Cedarwell Care Promise on every visit, and the 365-Day Done Right Promise on the finished work. Ben Ortega walks every cost line with you personally. As an independent Cover service provider, we’re not tied to Cover’s warranty process, but we build to Cover’s factory specs and exceed them where San Diego requires it. Know the number before the shovel moves. Call (858) 988-6447 to schedule a free estimate.
FAQs
Converting the garage changes how a portion of the home is used, so the original Cover warranty on the garage structure typically ends at conversion. However, our 365-Day Done Right Promise covers the work we do, and we document every modification with photos and notes so future issues are easy to trace. Call (858) 988-6447 if you want us to review your existing Cover warranty language before you commit to a conversion.
Most permit-ready Cover garage conversions take 10 to 16 weeks of construction time once permits are issued. The permitting phase in the City of San Diego adds 4 to 8 weeks depending on your neighborhood and whether you need design review. We give you a written schedule with every phase dated before we start.
Cover uses a clean, minimal interior with flush reveals and consistent trim. We match panel seams, floor transitions, and window trim to the existing home as closely as possible, and we can source the same or compatible materials through San Diego suppliers. Where an exact material is no longer available, we show you three comparable options and let you choose.
For most Cover lots in San Diego, converting the garage costs 30 to 40 percent less than building a detached ADU from scratch, because the shell, roof, and foundation already exist. But garage conversions also give up parking and storage space. We’ll price both options so you can compare real numbers, not guesses.
No. We write a fixed price before any work begins and honor it through the final inspection. The only thing that changes the number is if you ask us to add scope, like an extra window or upgraded flooring, and we’ll give you a new written price for that change before we do the work. Call (858) 988-6447 for an exact quote on your Cover garage.
