Cover Garage Conversion Contractor in Orange County: What to Know First
Garage conversion costs in Orange County typically run $95,000 to $190,000 for a permitted conversion with plumbing and electrical, and $130,000 to $280,000 for a full detached or attached ADU with its own kitchen and bath. A Cover backyard studio or ADU conversion usually takes 10 to 16 weeks from permit submission to final inspection, depending on the scope and how quickly the city reviews plans. We give you a written price before any work starts, and we show up in the window we give you. If you own a Cover unit in Orange County and need a garage conversion contractor who knows the product, call (350) 203-6060 and talk to a live person, day or night.
This page is for homeowners in Orange County who already have a Cover structure, or are planning one, and want a contractor who understands how Cover units are built, where they fail, and what it takes to get a garage conversion permitted in cities like Anaheim, Orange, Fullerton, and Santa Ana. Russ Delmar leads our Orange County crew, and he has spent years working on garage conversions and ADUs across this county, including the Anaheim Hills neighborhoods where deep lots and underused garages are common.
How Cover Products Fail – and How We Fix Them
Cover designs and builds prefab backyard homes and ADUs at its Gardena factory, about 40 miles up the 405 from most of Orange County. The units are panelized, steel-framed, and delivered in modules. That matters for a garage conversion contractor because the failure points on a Cover structure are different from a stick-built garage. Here is what we see and what we do about it:
- Module seam movement in Cover Studio and Cover ADU lines. Prefab modules settle independently after delivery, which can open small gaps at interior wall seams where modules join. In Orange County, the combination of dry summers and occasional heavy winter rain cycles makes this worse. We realign and refasten the seam joints, then retape and texture so the wall reads as one continuous surface.
- Exterior cladding penetrations that leak. Cover units use a rainscreen cladding system, often with metal or composite panels. When a garage conversion ties into the unit with new penetrations for electrical, plumbing, or a connecting breezeway, the flashing work is the difference between a dry wall and a mold problem. We flash every penetration with the same detailing the factory would use, then test with water before closing anything up.
- Under-slab plumbing rough-in issues on Cover lots. Cover unit slabs are factory-poured, but the site plumbing connection is field-installed. We regularly find drain lines that were not properly bedded, which causes settlement at the connection point. Since Orange County requires trench inspections before backfill, we dig, correct the pitch, and schedule the inspection before the trench gets covered so there is no second dig.
- Electrical panel capacity limits in older Orange County garages. A garage conversion needs a subpanel that can carry kitchen circuits, HVAC, and a full bath. Many Orange County homes built in the 1960s and 1970s have 100-amp panels, which will not pass a final inspection for a full ADU conversion. We include panel upgrades in the written quote when needed, so the price you see covers what the inspector will actually require.
- HVAC condensation problems in Cover units. The steel frame means fewer thermal breaks, and in Orange County’s coastal humidity, the mini-split lines can sweat inside the wall cavity if the line set insulation is compromised or poorly taped. We open the wall only where needed, replace the line insulation, and confirm the condensate line drains before we close up.
Our Cover Garage Conversion Contractor Process
Every Cover garage conversion in Orange County follows the same path. You will know the price before we start, and you will know who is on your property every day.
- 1
Site walk and written scope. We come to your Orange County property, measure the garage and the lot setbacks, and talk through what you need the space to do. You get a written scope of work with real numbers, not a ballpark.
- 2
Permit set and submission. We draw the conversion plans, including the Cover unit tie-in details, and submit to your city. Orange County cities vary, but expect 3 to 8 weeks for plan check on a garage conversion.
- 3
Demolition and structural work. We strip the garage interior, reinforce the slab and framing where the conversion requires, and run the new systems. The job site gets cleaned at the end of every day.
- 4
Cover unit integration. If you are connecting your conversion to a Cover unit, this is the step where we handle the tie-in flashing, weatherproofing, and mechanical connections. We use materials that match the Cover spec so nothing looks patched on.
- 5
Inspections and closeout. We schedule every required inspection, walk the project with you before final sign-off, and hand you the written Kingswell Guarantee covering the work for 365 days. If something is not right, we come back.

Why Orange County Homeowners Call Lodgewick ADU Orange County for Cover Work
We are an independent Cover service provider, not an authorized dealer or installer. That independence matters because we work for you, not for a manufacturer’s warranty department. Our crew includes technicians who have worked on Cover units, Abodu units, and Dvele homes, so when a tie-in detail or a seam issue comes up on your garage conversion, someone on site has seen it before. Russ Delmar grew up in the San Gabriel Valley where his dad rebuilt everything that could be rebuilt, and he brought that habit to Orange County. The Kingswell Guarantee rides on every job: a written price before work begins, a defined arrival window, a clean job site, and a written 365-day guarantee. If the work fails within that year, we come back free. A live person answers our phones 24 hours a day, including when you call at 9pm to ask about a permit question. Tell us what you need the space to do, and we will figure out the honest way to get there.
FAQs
Yes, we perform garage conversion work on Cover units under warranty. We are an independent contractor, so any warranty claim stays between you and Cover, but we document everything we find and can provide photos and notes to support your claim. The work we do is covered by our own written 365-day guarantee.
Yes. We do this regularly in Orange County, and the key detail is the connection point. We detail the flashing, drainage, and utility tie-ins so the conversion and the Cover unit read as one integrated structure, and we pull permits for the entire scope so the final inspection covers both.
Most garage conversions run 10 to 16 weeks from permit submission to final inspection. The city plan check is usually the longest single step, and we cannot speed up a municipal reviewer. What we can do is have the plans submitted correctly the first time, which avoids resubmission cycles that add weeks.
No. The written price we give you before work begins is the price you pay. If we find a hidden condition like a failed slab or a buried sewer line that changes the scope, we stop, show you what we found, and agree on any adjustment in writing before we continue. That is how The Kingswell Way works: say the price before the work.
Yes. Every garage conversion and ADU we build is permitted through the city. Unpermitted conversions are a liability when you sell the home, and Orange County cities increasingly flag them during title searches. We handle plan submittal, inspections, and final closeout, and you get the signed permit card at the end.
