Boxabl Garage Conversion Contractor in Los Angeles: What to Know First
Boxabl garage conversion contractor work in Los Angeles typically involves preparing your existing foundation and site for a Casita’s arrival, then handling the on-site connection work: utility tie-ins, permitting, and the finishing details that turn a folded steel module into a legal, livable dwelling. Most Boxabl garage conversion projects we take on run $45,000 to $95,000 all-in, depending on site conditions, utility distances, and how much of the finish work you want us to handle. We give you a written price before any work starts, and that number doesn’t move at the door.

This page is for Los Angeles homeowners who already own a Boxabl or have one on order, and who need a contractor who actually understands how these units go together and what can go wrong when they’re placed on a residential lot. If that’s you, call (254) 602-5618 and you’ll get a live person, not a voicemail tree.
How Boxabl Products Fail – and How We Fix Them
Boxabl builds a genuinely interesting product, and we’ve worked on enough units in the Los Angeles area to know where the real-world problems show up. Most of what we fix falls into a short list:
- Folding seam seal degradation on the Casita 2.0. The hinge lines where the walls fold out are the unit’s most exposed joints, and after a few Los Angeles summers with 90-plus degree days followed by cool nights, the factory sealant can shrink and crack. You’ll see dust lines or feel drafts along the fold seams. We strip the old bead, re-seal with a marine-grade polyurethane, and test with a blower door before we call it done.
- Underside moisture intrusion on units placed directly on a slab. Boxabl’s design assumes a level, well-drained pad. If your existing garage slab has any settling or slope, water pools under the steel floor cassette and wicks up through the joints. In neighborhoods like West Adams and Leimert Park, where older slabs are common, this is the number one call we get. The fix is proper shimming, perimeter sealing, and sometimes a retrofitted drainage channel.
- Utility connection mismatches. The Casita ships with standard 50-amp electrical and single-point water/sewer connections, but Los Angeles DWP service drops and older sewer laterals don’t always line up where the unit’s ports are. We handle the trenching, conduit runs, and panel work to bridge that gap, and we pull permits so the work passes inspection the first time.
- HVAC stress from direct sun exposure. The factory mini-split in a Boxabl is sized for the unit’s square footage, not for a placement that gets full western exposure against a south-facing Los Angeles wall. We’ve replaced or supplemented several units with higher-capacity systems after homeowners in places like Woodland Hills and Tarzana found August cooling couldn’t keep up. When we see a unit going in hot, we address it at placement rather than waiting for a failure.
- Interior trim and panel gaps after transport. Steel modules flex during lifting and setting, and some interior panels and corner trim pieces can shift. It’s not structural, but it’s visible. We realign, re-fasten, and caulk as part of every Boxabl finishing package we do.
Our Boxabl Garage Conversion Contractor Process
We follow the same steps on every Boxabl job, whether it’s a single Casita on an existing slab or a multi-unit site. You’ll know what’s happening at every stage because Russ Delmar walks you through it before we start.
- 1
Site walk and honest talk. We come to your Los Angeles property, look at the placement area, the utilities, and the access route, and tell you what’s actually feasible. No deposit required for that conversation.
- 2
Written proposal. You get a line-item price for every phase: site prep, utility runs, placement coordination, interior finish, and permit closeout. That’s your number.
- 3
Permits and coordination. We handle Los Angeles Department of Building and Safety submittals and schedule inspections. If Boxabl or your dealer is coordinating the module delivery, we work directly with them on timing and crane access.
- 4
Site prep and utility rough-in. We level, compact, and prep the pad, run electrical conduit, water, and sewer to the exact connection points, and set anchor points per the factory spec.
- 5
Placement day support and connection. When the unit arrives, we’re on site to manage the set and immediately begin utility connections, seam sealing, and structural tie-downs.
- 6
Interior finishing and final walkthrough. Trim, caulk, paint touch-ups, fixture checks, and a full system test. You get the written guarantee before we consider the job complete.

Why Los Angeles Homeowners Call Lodgewick ADU Builders for Boxabl Work
We’re an independent Boxabl service provider, not a Boxabl dealer and not affiliated with the manufacturer. That matters because we don’t have a sales quota on new units. Our job is to make the unit you already own work correctly on your property.
Every Boxabl project we take runs under The Kingswell Guarantee: a written price before work begins, a real arrival window, a clean job site every day, and a written guarantee on the finished work. If something we built or connected fails within 365 days, we come back and fix it. Free return visit. That’s the 365-Day Done Right Promise, and it’s in writing on every job.
Russ Delmar, our owner, grew up in Eagle Rock and studied construction technology at Los Angeles Trade-Technical College downtown. He spent years on residential builds across the Eastside before focusing entirely on ADUs. When a homeowner asks whether a Boxabl makes sense for their garage conversion, he’ll give you a straight answer, including when it doesn’t. We also work with Abodu, Cover, and Dvele units regularly, so if your project shifts direction, we’re not starting from scratch.
FAQs
Yes. We handle installation, connection, and finishing work that falls outside the factory warranty, and we document everything so your manufacturer coverage stays intact. We won’t do anything that voids a warranty, and if we see a potential factory defect, we’ll tell you to file it before we proceed.
Most garage conversion projects take 8 to 14 weeks from permit submittal to final inspection. Permitting with the Los Angeles Department of Building and Safety is usually the longest variable, and we manage that entire process for you. Site prep and connection work typically runs 3 to 6 weeks once permits clear.
Yes, we pull all required permits for the site work, utility connections, and any structural work. A Boxabl placed without permits can create problems when you sell the home or if a neighbor files a complaint. We handle it legally from day one.
Often yes, after demolition and site prep. The existing garage slab may be usable if it’s level and in good condition, but many older Los Angeles garages have slabs that are cracked or unpermitted. We’ll assess it during the site walk and give you a straight answer on whether to reuse or pour new. Call (254) 602-5618 for a free site assessment.
If work we performed fails within 365 days, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s written into your project documents before we start. You’ll have a live person on the phone when you call, and we’ll schedule the return visit for a specific window.
