A garage conversion in Lomita typically runs $85,000 to $160,000 before permit fees, depending on whether you’re adding a simple bedroom or building out a full ADU with a kitchen and bath. Most projects take 10 to 16 weeks from first walkthrough to final inspection. If you’re on a 1950s or 1960s tract lot near Oak Street or off 250th, you already know the detached garage sits tight to the rear or side line, which makes the zoning-envelope work as important as the framing.
Fielding ADU Builders is a Garage Conversion Contractor that works the way Lomita homeowners want a contractor to work: written price before any work starts, permits pulled by the book, a full year of written guarantee on the finished job, and a live person on the phone when you call.

Why Fielding ADU Builders Is Lomita’s Preferred Garage Conversion Contractor Company
Lomita homeowners don’t need a contractor who promises a price and then revises it at the slab pour. They need someone who has already measured setbacks on Narbonne-adjacent lots, confirmed the thickness of a 1962 detached-garage slab, and knows which panel upgrades the inspector will ask about before drywall goes up. Our business runs on The Garrison Standard: the written price on day one is the price on the final invoice. No change orders invented mid-job, no surprise line items at the end.
The crew that shows up in Lomita is background-checked and in uniform. You’ll know who is walking your property, which matters when work stretches across several weeks. Garrison Partners has operated to this standard since 2006, and Fielding ADU Builders carries it into every garage conversion, ADU, and room addition we build in Lomita.

Garage to Bedroom Conversion in Lomita
Garage to Bedroom Conversion in Lomita usually means taking a detached or attached garage and turning it into a finished, conditioned bedroom with a closet, egress window, insulation, drywall, and dedicated electrical. On a typical Lomita tract lot this runs $45,000 to $85,000, with the biggest cost drivers being the condition of the slab, whether the garage shares a wall with the house, and how far the existing wiring is from current code.
Slab and waterproofing checks
Many Lomita garages built in the 1950s and 1960s sit on a slab that was poured for parking, not for habitable space. We measure thickness, check for moisture migration, and confirm the floor is level enough for finished flooring. If the slab needs work, that cost is real and it’s better to know it before framing begins, not after inspection fails.
Heating, cooling, and egress
A bedroom has to be conditioned space. That means a mini-split or tied-in HVAC, plus a proper egress window sized to Lomita’s building code. We install both as part of the permit scope, and the inspector verifies them before final sign-off.
Garage Conversion ADU in Lomita
Garage Conversion ADU in Lomita converts the existing garage shell into a permitted accessory dwelling unit, usually a studio or one-bedroom with a kitchenette, bathroom, and separate entrance. These projects run $95,000 to $160,000 in Lomita. The range is wide because the electrical panel upgrade, slab condition, and whether you keep the original garage footprint all move the number in real dollars.
Detached garage ADUs and setback reality
Lomita’s older detached garages often sit within a few feet of the rear or side property line. That triggers setback review and may require a variance, which is the city’s written permission to build closer to the line than the standard rule allows. We’ve worked through that process in Lomita and we’ll tell you honestly if it applies to your lot before we write the price.
Kitchenette, bath, and panel upgrades
An ADU needs a full electrical service assessment. A 100-amp panel that ran a garage door opener and a light bulb is not going to carry a mini-split, cooktop, water heater, and bathroom circuit. We price the panel upgrade as part of the job, not as a surprise change order at week six.
Trusted Brands We Service in Lomita
We work with the systems Lomita homeowners are already researching. On garage conversions we regularly finish exteriors in James Hardie siding to match the existing house, and on ADU work we’re fluent with prefab platforms including Abodu and Cover for clients who want a faster path through design and fabrication. That doesn’t mean we push prefab over conventional framing. It means we can give you a real comparison of build speed, cost, and finish quality for your specific Lomita lot, then let you choose. If you’re leaning toward conventional framing, we’ll spec James Hardie or equivalent materials that hold up to coastal air and look right on a 1960s rancher.
Common Garage Conversion Contractor Problems We See in Lomita Homes
- Uninspected slab work: In Lomita’s older detached garages the original pour is often not thick enough or dry enough for habitable space under current code. We check this first, before framing money gets spent.
- Undersized electrical panels: Adding a kitchenette, bathroom, and HVAC to a garage that once powered only a door opener and one outlet creates a real load problem. We price the panel upgrade upfront.
- Missed ADU permitting: A garage-to-ADU conversion in Lomita’s residential zones has separate permitting, setback, and parking-replacement requirements. Skipping that separate approval is a fast way to get a stop-work order.
- Detached garages near property lines: Setback variance work is common on Lomita lots where the garage sits close to the side or rear line. We’d rather tell you that at the estimate than let it surprise you at the permit counter.
Pricing for Garage Conversion Contractor in Lomita, CA
Plan on $45,000 to $85,000 for a garage-to-bedroom conversion in Lomita and $95,000 to $160,000 for a garage-to-ADU conversion, before permit fees. Permits and inspections in Lomita typically add $3,000 to $7,000 depending on scope. The wide ADU range is driven by slab condition, electrical panel capacity, whether a setback variance is needed, and your finish level: a basic studio with a compact kitchenette costs less than a one-bedroom with full appliances and a James Hardie exterior package.
We hand you a written, line-item price before any work starts. If something inside the walls is worse than it looked, we bring it to you with photos and a number you can approve or reject. That’s the Garrison Code: show up in the window, price in writing, by the book, leave it clean, stand behind it for a year.

FAQs About Garage Conversion Contractor in Lomita
It runs in this order: site walk and measurements, slab assessment, architectural and structural drawings, permit submission and plan check, any needed setback variance, demolition and slab prep, framing, rough electrical and plumbing, panel upgrade if required, insulation and drywall, finishes, and three to four city inspections before final sign-off. In Lomita, the site walk almost always includes checking the garage’s distance from the rear and side property lines, because that determines whether your ADU needs extra zoning review. Call (361) 315-4177 and we’ll walk your lot and give you the sequence in writing, specific to your address.
Most garage conversion ADUs in Lomita take 12 to 16 weeks from permit submission to final inspection. A simple garage-to-bedroom conversion without a kitchen or bath runs closer to 8 to 10 weeks. The biggest schedule variables are plan check turnaround at the city and whether a setback variance is required for a detached garage near the property line. We recently completed a detached two-car garage conversion into a one-bedroom ADU in Lomita where verifying the slab, upgrading the panel, and coordinating three inspections added roughly two weeks compared to a simpler bedroom scope. Call (361) 315-4177 for a realistic calendar on your specific lot.
The honest answer is: slab condition, electrical panel capacity, and what the city says about your setbacks. If the slab is too thin or wicking moisture, you’ll pay to remediate or re-pour. If the panel can’t carry the new loads, you’ll pay for the upgrade. If the garage is too close to the side or rear line, you may need a variance, and that takes time and money. We work to lock these answers into the written price before we start, which is exactly why we do the slab check and panel assessment on the front end. Call (361) 315-4177 if you want that level of pricing discipline on your Lomita project.
You need a separate ADU permit for a garage conversion ADU in Lomita. It is not folded into a house remodel permit. The ADU scope includes distinct plan check, setback review, parking-replacement evaluation where applicable, and its own inspection sequence. A garage-to-bedroom conversion that stays within the main dwelling may qualify under a standard remodel permit, but an ADU with a kitchen and bathroom does not. We pull the permits ourselves and don’t start framing until they’re posted. Call (361) 315-4177 and we’ll tell you which permit path your garage actually needs.
Yes. We finish garage conversions to match the main house in roofline, siding, and trim. On recent Lomita work we matched a James Hardie siding package to the existing house on a converted detached garage ADU, so the finished unit reads as part of the original property rather than an attached afterthought. For stucco or board-and-batten homes, we match the texture and paint line, and we’ll show you samples before anything is installed. Call (361) 315-4177 and bring us a photo of your house; we’ll tell you what the exterior match will cost in your written estimate.
