An accessory dwelling unit (ADU) is a second, fully independent home built on a lot you already own, and in Koreatown that usually means converting a detached garage, finishing a basement, or adding a compact second story behind an existing courtyard building. Koreatown is one of the densest neighborhoods in Los Angeles, full of 1920s and 1930s apartment buildings, duplexes, and small courtyard complexes, so nearly every project here is about maximizing a tight footprint while navigating strict zoning and historic preservation rules. That’s exactly the kind of work Lodgewick ADU Los Angeles does every week. If you’re wondering whether your Koreatown lot can support an ADU, call (213) 698-7116 and we’ll walk you through what’s realistic.
Why Koreatown Homes Are Different

Koreatown’s housing stock doesn’t look like the rest of Los Angeles. Most of the neighborhood was built between 1920 and 1940, and the typical property is a stucco apartment building or duplex wrapped around a central courtyard, with a detached garage at the back of the lot and sometimes a basement that was never finished. Those old garages are often the single best ADU opportunity in Koreatown, but they come with a catch many homeowners don’t discover until the permit stage: a lot of them were built with unreinforced masonry or simple wood framing that needs seismic retrofitting before any conversion work can start. That’s a real cost, and it’s one we flag in writing during the estimate so it doesn’t surprise you later.
The climate works in your favor here. Koreatown has a mild Mediterranean pattern, warm and dry in summer, mild and wet in winter. ADUs in Koreatown rarely need heavy HVAC systems because the heating and cooling loads are modest, which keeps mechanical costs down. The bigger concern is water. These older foundations and flat-roofed garages have been absorbing winter rain for close to a century, so waterproofing and drainage details matter more here than in newer parts of the city. We plan for that from the first site visit.
Koreatown’s density also shapes what’s actually permitted. Many properties sit in historic preservation overlay zones, which means the city reviews exterior changes carefully, and lot coverage rules are tighter than in single-family suburbs. In practice, garage conversions and basement ADUs tend to be the most viable path to rentable square footage here, because they use space that already exists instead of adding a new footprint to an already tight lot. Our team knows which Koreatown blocks trigger preservation review and which ones don’t, and we factor that into every written price.
Our Main Koreatown Services
Koreatown homeowners most often call us about two things: adding living space to an existing structure, or turning an underused garage or basement into a legal, rentable ADU. Each service has its own Koreatown page with full pricing and project details.
Home Addition Contractor in Koreatown
Adding square footage in Koreatown means working with old buildings, tight setbacks, and, in many cases, a preservation review that dictates what the addition can look like from the street. A home addition here usually involves extending a ground-floor unit into courtyard space, building a second story over an existing duplex, or finishing a basement into livable rooms. Before we write a price, we check the foundation condition, the existing framing, and the zoning envelope, because those three factors drive cost more than anything else in this neighborhood. See Home Addition Contractor in Koreatown for typical ranges and timelines.

Garage Conversion Contractor in Koreatown
A garage conversion is often the fastest, most cost-effective way to add a legal ADU in Koreatown, because the structure already exists and you’re not expanding the building’s footprint. The catch is that many Koreatown garages were built decades before current seismic codes, so the job frequently starts with retrofitting the masonry or wood frame, then moves into insulation, electrical, plumbing, and a new foundation pour where the garage door used to be. Those steps are all included in our written price, with no change orders at the door. Full details are on the Garage Conversion Contractor in Koreatown page.

ADU Builders in Koreatown
Some Koreatown lots can support a detached ADU, and in those cases we help you choose between a site-built structure and a prefab unit from a manufacturer we know well, then handle the foundation, utilities, and finishing work. Detached ADUs on Koreatown’s small lots usually mean a compact one-bedroom footprint, and we work through the setback and height rules early so the design fits the lot on paper before any money is spent on construction. Our Koreatown ADU team covers everything from the first lot feasibility check through final inspection. See ADU Builders in Koreatown for pricing and options.

What pushes a Koreatown job toward the high end is usually the condition of the existing structure, an unreinforced masonry garage that needs full seismic retrofit, or a preservation review that requires custom exterior detailing. The opposite is also true: a garage in good shape on a clear-title lot can land near the bottom of these ranges. Either way, you get a written price before any work starts, and that number doesn’t change at the door.

FAQs About ADU Company in Koreatown

Most estimates in Koreatown are scheduled within a few business days of your call, and our crews reach most addresses in the neighborhood within 30 to 45 minutes for site visits and ongoing check-ins. Call (213) 698-7116 and a live person will set a specific window for the visit.
Many do. Koreatown has several historic preservation overlay zones, mostly concentrated around Wilshire and the older courtyard districts, and if your property falls inside one, the city will review exterior changes before issuing permits. We check this early and include any required review time in your written timeline.
Yes. A large share of Koreatown garages built before 1940 were constructed with unreinforced masonry or light wood framing that doesn’t meet current seismic standards, so retrofitting is often the first step of a conversion. We bundle the retrofit into one written price with the conversion itself, so you’re not dealing with two contractors and two change-order risks.
