Fast, Reliable ADU Builders Across Cudahy
ADU construction in Cudahy usually costs between $85,000 and $240,000 depending on whether you’re converting an existing garage or building new, and the permitting process takes 4 to 9 months before construction starts. Our ADU Builders team works on the dense post-WWII lots that define this city, where lot-coverage math and unpermitted prior work shape almost every project. If you’re weighing a JADU conversion or an interior split on a 4,000 sq ft parcel, call us at (254) 602-5618 and we’ll walk the property, check the setbacks, and give you a written price before any work begins.
Why Lodgewick ADU Builders Is Cudahy’s Preferred ADU Builders Company
Founded in 2010 as part of the Kingswell family of home-service companies, Lodgewick ADU Builders has spent years on the kinds of lots that dominate Cudahy: small, tightly packed, and often carrying decades of informal additions. We know what the building department flags on a 5,000 sq ft parcel, and we know what happens when a wall opens on a 1940s bungalow. That local familiarity saves our Cudahy customers weeks of back-and-forth and thousands in rejected plans.
Every project runs under The Kingswell Guarantee: a written price before work starts, a defined arrival window, a clean job site, and a written guarantee on the finished build, with a free return visit if anything fails within the 365-day period. Russ Delmar, who leads our team, insists on that guarantee being in writing before a single nail is driven. That’s the only way a homeowner on Santa Ana Street or Wilcox Avenue knows exactly what they’re paying for and what happens if something isn’t right.
Our crews are background-checked and uniformed, so you always know who’s on your property. And when you call with a question about your build or your guarantee, a live person answers. 24 hours a day, 7 days a week. Not a voicemail. Not a chatbot.
Backyard ADU in Cudahy
Backyard ADU work in Cudahy rarely means a freestanding new build, because lot-coverage limits and tight setbacks on those 4,000 – 5,500 sq ft parcels make detached construction nearly impossible on most blocks. What we do instead is convert the single-car detached garage that already sits at the back of the lot into a permitted, livable unit. A garage-conversion ADU in Cudahy typically runs $85,000 – $150,000 depending on whether we need to rebuild the slab, add a subpanel, or legalize prior unpermitted work.
Slab and Foundation Repairs
The most common surprise on Cudahy garage conversions is the slab. Many were poured thin in the 1940s and 1950s, then cracked over decades of Southern California settling. We inspect the slab edge before we frame, and if it’s compromised, we price the rebuild in writing before we touch it.
Legalizing Prior Conversions
A significant share of the backyard structures on Cudahy lots were converted informally years ago. Under SB 897, many of those can be brought into compliance, but the process requires documentation and the right sequence with the city. Russ Delmar’s team handles that legalization as part of the build, not as a surprise you discover halfway through.
ADU Construction in Cudahy
ADU Construction in Cudahy almost always begins with a conversation about what’s already on the lot, because this city’s density means interior unit splits and JADU garage conversions are the projects that actually get permitted. A full interior split or garage-to-JADU conversion here generally runs $85,000 – $180,000, while a rare detached new build on a larger parcel starts around $200,000 and climbs to $240,000 or more. The single biggest variable is what we find when walls open, which is why our process starts with an inspection, not a photo-based quote.
Interior Unit Splits
On a 1,200 sq ft bungalow, splitting off a 400 sq ft junior unit means reworking plumbing, adding a kitchenette, and sometimes upgrading the main panel. We price these by the actual condition of the home, not by a generic square-foot formula, because a 1948 house on Atlantic Avenue has different bones than a 1962 cottage on Live Oak Street.
JADU Garage Conversions
A JADU is a junior accessory dwelling unit, and in Cudahy it’s the workhorse of the market. We convert the existing single-car garage into a compact unit with its own entrance, bathroom, and efficiency kitchen. The permit path is faster than a detached ADU, and the existing structure means less new foundation work, which keeps costs on the lower end of the range.
Trusted Brands We Service in Cudahy
We work hands-on with leading ADU and materials brands, and we match them to the lot and the budget, not the other way around. For Cudahy’s small parcels and post-WWII structures, we often specify James Hardie siding for its fire resistance and low maintenance, and we build with Abodu or Cover prefab systems when a modular approach fits the timeline. For garage conversions where the existing shell is sound, Dvele’s high-performance envelope details inform our insulation and air-sealing approach. Because we stock common materials and hardware for these systems locally, turnaround on a Cudahy job doesn’t stall waiting on a part from out of state. Using established brands also means your written guarantee is backed by manufacturer warranties we can actually service, not a product we installed once and never saw again.
Common ADU Builders Problems We See in Cudahy Homes
- Unpermitted prior conversions. Families converted garages or added backyard rooms decades ago without permits, and now those units block the new permit until they’re legalized under SB 897. We document the existing work and sequence the legalization before the new build begins.
- Thin, cracked slabs. Cudahy’s 1940s – 1960s detached garages were often built on slabs poured too thin for today’s live-in standards. We inspect the slab edge and any visible cracking before framing, and the repair goes into the written price.
- Knob-and-tube wiring feeding the garage. On older bungalow blocks, the garage circuit sometimes still runs on outdated wiring from the house panel. Opening that wall during a JADU conversion triggers a code upgrade, so we build an allowance into the contract rather than springing it on you mid-project.
- Mid-90s summer heat with no cooling plan. Cudahy sits inland enough that marine-layer cooling never reaches it in July and August. A garage-conversion ADU without proper insulation and a correctly sized mini-split becomes unlivable, not just code-compliant. We size HVAC for Cudahy’s actual summer temperatures, not for a generic Southern California number.

FAQs About ADU Builders in Cudahy
On most Cudahy parcels, no, a detached backyard ADU will not clear the lot-coverage and setback requirements, because this city packs roughly 19,000+ people per square mile onto parcels that mostly run 4,000 – 5,500 sq ft. The workable path is usually a JADU garage conversion or an interior unit split, which is what we recommend and price for most Cudahy homeowners. Call (254) 602-5618 and we’ll check your specific lot math before you spend money on plans that won’t pass.
In many cases, yes, California’s SB 897 streamlining rules allow unpermitted garage and backyard conversions to be legalized, and we handle that process as part of the build. What we don’t do is pretend the old work isn’t there: we document it, bring the structure up to current code where required, and sequence the legalization before the new permit is pulled. Call (254) 602-5618 for an inspection and a written plan.
We typically find outdated wiring, some of it knob-and-tube, undersized or damaged framing, failed waterproofing at the sill plate, and code upgrades that the permit triggers once the wall cavity is exposed. On a 1940s bungalow block near Elizabeth Street, our crew opened a detached garage for a JADU conversion and found a thin cracked slab and knob-and-tube feeding the garage from the main panel. We rebuilt the slab edge, ran a new subpanel, and priced every fix in writing before closing the walls.
We size insulation and mini-split HVAC for Cudahy’s actual summer temperatures, which regularly push into the mid-to-high 90s because the marine layer that cools Long Beach never reaches this far inland. A garage conversion that’s only code-compliant will bake in July and August, so we frame, insulate, and specify cooling for livability, not just for the permit. Call (254) 602-5618 and we’ll show you the exact HVAC sizing for your structure.
In Cudahy’s predominantly multigenerational Latino community, most ADUs are built to house family: abuela, adult children, or a relative who needs to be close. That changes the design conversation, because the unit has to be comfortable and dignified for a family member, not a rental tenant. Everything we build in Cudahy assumes someone’s family is going to live in it. Call (254) 602-5618 to talk through what your family needs.
