Fast, Reliable ADU Builders Across West Hollywood
Adding an accessory dwelling unit in West Hollywood typically runs $150,000 to $450,000 depending on whether you convert an existing garage, build detached on a slab, or tackle a carport-to-ADU project on a dingbat building. Most West Hollywood ADU projects move through design, permitting, and construction in 10 to 18 months, with soft-story retrofit overlaps adding 3 to 6 months when they apply. Our ADU Builders team works across the 90069, 90046, and 90048 zip codes, and we know what WeHo’s planning department will flag before you ever file. Call (254) 602-5618 for a written price before any work starts.
Why Lodgewick ADU Builders Is West Hollywood’s Preferred ADU Builders Company
Lodgewick ADU Builders is the ADU company of the Kingswell family, established in 2010. Russ Delmar leads our West Hollywood work, and he has spent enough time on WeHo parcels to know that this city’s building stock does not behave like the rest of Los Angeles. A 1930s bungalow court near Santa Monica Boulevard has different bones than a 1960s dingbat on Holloway Drive, and the permit path reflects that.
What separates us in West Hollywood is the way we open a project. We do not bid a garage conversion from the curb. We walk the property, check the RSO status, look at the carport structure, and write allowances for what we expect to find inside the walls. That written price comes before any work begins, and it stays written. If the framing is undersized or the sill plates are failing, we price it, get your approval in writing, and only then touch a stud.
Every call to (254) 602-5618 is answered by a live person, day or night. That matters in West Hollywood, where a question about your permit status or seismic retrofit designation does not wait for business hours.
JADU in West Hollywood
A JADU in West Hollywood – a junior accessory dwelling unit, typically carved out of existing bedroom or attached garage space inside the footprint of your current home – is the fastest path to a rentable or family unit when your lot is already built out to the property line. Most West Hollywood JADU projects run $80,000 to $160,000, and because they stay within existing walls, they sometimes avoid the full soft-story review that a detached conversion triggers.
What a WeHo JADU Actually Requires
A West Hollywood JADU needs its own entrance, an efficiency kitchen, and a bathroom that is either private or shared with the main dwelling. West Hollywood also applies its own standards to JADU permitting, including a maximum 500 square feet and the requirement that the owner occupy either the JADU or the main house. We handle the full plan set the city will actually approve.
When a JADU Makes Sense on Your Lot
If you are on a 4,500-square-foot R1 lot off Fountain Avenue with a 1920s Spanish Colonial that cannot spare rear-yard space, a JADU inside the existing envelope is often the only buildable option. We see this constantly in West Hollywood, where the 1.9-square-mile grid leaves almost no room for a detached unit.
ADU Plans in West Hollywood
ADU Plans in West Hollywood – the architectural drawing set, structural calculations, Title 24 energy documentation, and site plan the city requires before issuing a permit – run $8,000 to $25,000 depending on whether your project is a standard prefab installation or a custom design on a hillside-adjacent lot. In West Hollyood, the plan set is where the RSO audit and soft-story determination get baked in, so skipping this step is not an option.
Site-Specific Planning for WeHo Lots
West Hollywood lots are small, often irregular, and frequently on a slope where the base of the Hollywood Hills meets the flat grid. Our plan work includes a real site survey, a topo review for north-facing lots, and a check against the city’s setback and parking requirements before anything is drawn.
Permit-Ready Drawings With the Numbers Attached
We prepare ADU Plans with line-item cost allowances attached to the drawings themselves. That means when West Hollywood’s plan checker asks about structural upgrades to your dingbat carport, the number is already in your written price, not a surprise change order later.
Trusted Brands We Service in West Hollywood
Our West Hollywood crews work hands-on with established ADU manufacturers including Cover, Dvele, and Boxabl. For a compact rear-yard lot off Norton Avenue, a Boxabl or Dvele prefab unit can cut on-site construction time dramatically compared to stick-built. For higher-end custom work in the hillside-adjacent blocks north of Sunset, Cover’s panelized system works well on sites where crane access and foundation work are already complicated. We stock the local parts and detail packages these systems require for West Hollywood inspections, which keeps turnaround tighter than ordering from a warehouse two states away.
Common ADU Builders Problems We See in West Hollywood Homes
- Soft-story retrofit overlap on dingbat carports. WeHo’s mandatory seismic ordinance activates the moment you convert a carport-level space on a pre-1980 dingbat building, turning a straightforward ADU into a bundled structural project. We flag this on the first site visit, so you are never surprised mid-permit.
- RSO tenant-relocation exposure on multi-unit parcels. If your West Hollywood parcel has existing rent-stabilized tenants, a displacement during ADU construction can trigger mandatory relocation assistance payments and right-to-return obligations. We run the RSO audit before design begins.
- Pre-1940s wiring and framing behind the stucco. Opening walls on a 1920s – 1940s Spanish Colonial or Craftsman in West Hollywood almost always turns up cloth-wrapped knob-and-tube wiring, undersized framing at the sill plates, or both. We price the correction in writing before demolition, and you approve any discovery before we proceed.
- North-facing lot moisture against foundations. Hillside-adjacent blocks in West Hollywood, especially those angled away from the sun, accumulate shade and surface moisture that affects where you can place a detached ADU foundation and how you detail exterior waterproofing. We site and spec accordingly.
Pricing for ADU Builders in West Hollywood, CA

FAQs About ADU Builders in West Hollywood
Yes. West Hollywood’s Rent Stabilization Ordinance, which predates the city’s 1984 incorporation and is among California’s most protective, requires an RSO audit before design or permitting on any parcel with covered tenants. Displacing those tenants during ADU construction can trigger mandatory relocation assistance payments and right-to-return obligations that simply do not apply the same way on neighboring LA City or unincorporated county parcels. Call (254) 602-5618 and we will run the audit first, before anything else moves.
Because West Hollywood’s mandatory soft-story seismic retrofit ordinance activates simultaneously when you convert a carport-level space on a pre-1980 dingbat building. The structural upgrade is not optional, and it can push a $150,000 conversion into a $300,000+ bundled project. We flag this on the first site visit and write the seismic line item into your price from day one, so the number never moves on you. Call (254) 602-5618 for a written estimate that includes any retrofit work up front.
On most pre-WWII Spanish Colonial and Craftsman homes in West Hollywood, we find cloth-wrapped knob-and-tube wiring, undersized framing at the sill plates, and failed stucco waterproofing where exterior walls meet the foundation. We opened a 1920s Spanish Colonial on a north-facing hillside-adjacent block near Havenhurst and found all three. Our tech wrote a $150,000 garage-to-ADU allowance with a separate soft-story line item, priced the framing and wiring corrections in writing before demo, and the client approved each surprise before we touched a stud. Call (254) 602-5618 to get that same inspection-first process on your own WeHo property.
Yes. We do JADUs inside existing home envelopes and full ADU Plans for detached and garage-conversion projects across West Hollywood. JADUs in WeHo typically run $80,000 to $160,000 because they stay within existing walls; full ADU Plans run $8,000 to $25,000 and include the structural, Title 24, and site documents the city requires. Call (254) 602-5618 and we will tell you which path fits your lot before you spend a dollar.
West Hollywood sits at the base of the Hollywood Hills in a mild, near-coastal microclimate that rarely stresses ADU mechanical systems. But north-facing lots on hillside-adjacent blocks accumulate shade and surface moisture that can affect detached ADU foundation siting and exterior waterproofing details. We adjust foundation depth, drainage, and sill-plate flashing on those lots specifically, which is not standard practice on the flat sunny blocks south of Santa Monica Boulevard. Call (254) 602-5618 for a site-specific written quote.
