Get your free estimateFast, Reliable ADU Builders Across Century City
In Century City, an ADU rarely starts with a foundation. It starts with a board packet, a structural review, and a set of rules most contractors never read. That’s why our work here looks different from a typical backyard build. We convert penthouses, rooftop mechanical rooms, and underused square footage inside high-rise towers into fully permitted accessory dwelling units. If you own a unit in Century City and want to know whether your space can become a legal ADU, call (213) 698-7116. We’ll walk you through the review path before you spend a dollar on drawings.
Why Lodgewick ADU Los Angeles Is Century City’s Preferred ADU Builders Company
Our ADU Builders team has worked inside Century City towers long enough to know that the HOA architectural committee, not the city, approves your project first. That changes everything about how a job gets priced, scheduled, and filed. We’re led by Russ Delmar, who has guided high-rise ADU conversions through some of Los Angeles’s most demanding design-review boards. When a Century City unit owner calls us, they’re not explaining what an ADU is. They’re asking whether their roof deck can carry the added load, whether the board will accept a specific glass railing profile, and who files what when. We answer those questions in the first conversation.
Our crews serve Century City directly, with scheduling coordinated from our Los Angeles office. Every project operates under The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every job. If the work fails within 365 days, we come back at no charge. That promise is in writing, on every project, before the first tool leaves the truck.
ADU Plans in Century City
In Century City, an ADU plan is not a set of stock drawings. It’s a submittal packet built around your building’s specific architectural requirements: the materials, colors, railing profiles, and window types the HOA’s design committee has already approved for that tower. Getting the plans wrong means a rejection at first hearing and a resubmission window that might not open for another 60 to 90 days. We prepare plans that anticipate the committee’s objections before the hearing happens.
What a Century City plan packet needs
A workable submittal for a Century City ADU includes the same documents a single-family project needs: floor plans, structural calculations, electrical and plumbing layouts, and Title 24 energy compliance. But it also has to show the design committee that the new unit will not change the building’s exterior in any way they have not already blessed. That means material schedules with exact finishes, often matching the tower’s original bronze-anodized aluminum or painted steel specs. We build this packet ourselves and file it with the HOA coordinator before it goes to the city.
What ADU plans cost in Century City
Plan sets for a high-rise ADU conversion in Century City typically run $6,500 to $12,000, depending on whether structural peer review is required and how many design revisions the committee requests. A rooftop conversion with exterior changes can push the plan cost higher because the structural engineer has to verify point loads on an older slab. We give you that number in writing before any design work begins.
ADU Contractor in Century City
A garage conversion contractor in Century City has to run two schedules at once: the construction schedule and the review calendar. Miss either one and the job stalls. We’ve learned to file early, respond to committee comments within 48 hours, and stage materials so the build starts the week approvals come through. That’s the difference between a conversion finished in six months and one that sits half-open for a year.
Rooftop and penthouse conversions
Most of the ADU work in Century City is vertical, not horizontal. We convert rooftop mechanical rooms, penthouse storage areas, and unused service spaces inside existing towers. These jobs require structural peer review because older high-rise slabs were never designed for residential point loads like a kitchen island or a filled bathtub. We coordinate that review directly with a licensed structural engineer and file the report alongside the building permit.
What a Century City conversion costs
A penthouse or rooftop ADU conversion in Century City generally lands between $280,000 and $520,000 depending on square footage, finish level, and how much structural reinforcement the slab needs. A simpler interior conversion with no roof work starts around $180,000. These are real numbers from jobs we’ve priced in this market. Your written estimate will match what you pay unless you change the scope, and we don’t change prices at the door.
Trusted Brands We Service in Century City
Century City’s towers demand materials that hold up to coastal air and HOA scrutiny. We work with Cover, Dvele, and Boxabl for prefab and panelized ADU systems that can be lifted into high-rise sites where traditional stick framing is impractical. We also specify marine-grade 316 stainless fasteners, anodized aluminum railings, and exterior claddings matched to the tower’s original palette, because the committee will reject anything that looks like a suburban addition bolted onto a 1960s high-rise. We keep local material lead times short and order long-lead items the same week the board approves your plans.
Common ADU Builders Problems We See in Century City Homes
- Submitting standard residential materials and getting rejected at first hearing. Most ADU packets drafted for single-family lots specify powder-coated steel or standard glass railing profiles. In Century City, the board wants the tower’s original finishes, often bronze-anodized aluminum or marine-grade stainless. We match the spec before submission, not after rejection.
- Underestimating the HOA review calendar. Century City boards often meet monthly or quarterly. If you miss a resubmission deadline, the next hearing might be 90 days out. We track every board date for your building and submit with enough lead time to land on the next available agenda.
- Skipping the structural peer review on a rooftop or penthouse conversion. The building department will issue a stop-work order if the slab hasn’t been verified for the point loads of a new kitchen or bath. We file the structural report with the permit so the job never stalls mid-build.
- Buying fixtures that corrode in marine air. Century City sits close enough to the coast that standard exterior hardware starts to pit within a couple of years. We specify corrosion-resistant materials from the start, so a rooftop ADU does not need a hardware replacement two years after completion.
Pricing for ADU Builders in Century City, CA
A full ADU conversion in Century City’s high-rise towers runs from $180,000 for a simple interior unit up to $520,000 for a penthouse or rooftop build with structural reinforcement and exterior work. Plan sets add $6,500 to $12,000 and are quoted separately so you know exactly what the design phase costs before you commit. Structural peer review, when required, typically adds $4,000 to $9,000 depending on the building’s age and slab condition. The biggest cost drivers are HOA-mandated finishes, crane time for rooftop material delivery, and whether the slab needs load verification. Call (213) 698-7116 and we’ll price your specific unit. Estimates are free and written.

FAQs About ADU Builders in Century City
In a single-family neighborhood, the city reviews your plans and you build. In Century City, the HOA architectural committee reviews your plans first, and they apply their own design standards: material finishes, railing profiles, exterior colors, and even window types. Only after the board approves can you file for a building permit with the city. That committee layer typically adds 60 to 120 days to the calendar, and a rejection resets the clock until the next hearing date. Call (213) 698-7116 if you want us to look at your building’s specific review schedule.
Yes, but only if the building’s CC&Rs allow rooftop improvements and the slab can carry the added load. Most Century City towers built in the 1960s and 1970s were not designed for residential point loads on the roof, so a structural peer review is almost always required. That review is filed with the building permit. We’ve completed rooftop conversions in Century City, including a penthouse mechanical room on Avenue of the Stars, so the path is proven. Call (213) 698-7116 and we’ll tell you what your roof can handle.
The contractor files the permit after the HOA design committee issues its approval. In our process, we prepare the full submittal packet, file it with the board coordinator, attend the hearing if needed, and then file the city building permit the same week the approval letter is issued. The unit owner’s signature is required on the HOA application, but we handle the filings and coordination. Call (213) 698-7116 for a rundown of your building’s exact process.
Most Century City towers require corrosion-resistant metals: anodized aluminum, marine-grade 316 stainless steel, and exterior finishes matched to the building’s original 1960s or 1970s palette. Standard residential materials like powder-coated steel railings or zinc-plated hardware typically get rejected because marine air corrodes them and the board wants visual continuity. We specify materials that meet both the HOA’s design standards and the durability demands of a coastal high-rise. Call (213) 698-7116 if you have a material schedule from your board and want a second read.
We file early, respond to committee comments within 48 hours, and never start demolition until the board’s approval letter is in hand. The mistake most contractors make here is starting interior work before the design review completes, then getting a stop-work order and a half-open unit. We build the review calendar into the project schedule from day one, so materials arrive the week approval comes through and the job moves without a gap. Call (213) 698-7116 and we’ll walk you through a sample schedule for your building.
