Fast, Reliable Garage Conversion Contractor Across Hollywood
For a garage conversion in Hollywood, the price typically lands between $120,000 and $190,000 for a full permitted ADU with kitchen and bath, while a simpler garage-to-bedroom build runs $60,000 to $95,000. The two things that move that number most in this neighborhood are whether the garage sits inside one of Hollywood’s Historic Preservation Overlay Zones and what the walls hide once they’re open. Ben Ortega and our Garage Conversion Contractor team screen for both before we ever hand you a written price. Call (707) 383-5338 to talk through your lot.

Why Seedling ADU Builders Is Hollywood’s Preferred Garage Conversion Contractor Company
Hollywood homeowners keep telling us the same thing: they expected a contractor, and they got a process. We show up to the first walkthrough with shoe covers on, a moisture meter in hand, and a printed HPOZ map of your block so we can tell you on the spot whether Spaulding Square or Whitley Heights design review applies to your rear-alley garage. That one conversation saves months of redesign later.
Ben Ortega runs every Hollywood estimate personally. He walks the alley access, checks the existing slab, opens the electrical panel if it’s safe to do so, and then writes a line-by-line price before any work starts. No allowances that balloon later without your signature. Our crews are background-checked and uniformed, and the Cedarwell Care Promise means drop cloths on the floors, pet-safe products where there’s a choice, and a photo of the cleanup before the crew leaves your Hollywood property each day. A live person answers the phone around the clock during your build.
Garage Apartment Conversion in Hollywood
Garage Apartment Conversion in Hollywood means turning a detached rear-alley garage, often from the 1920s or 1930s, into a rentable or family unit with its own entrance, bath, kitchenette, and separate address. On the flats below Franklin Avenue, most of these garages are one-car Spanish Colonial Revival structures with stucco exteriors and low pitched roofs. Converting one properly means preserving that streetscape language, especially when an HPOZ sits over the lot. A full garage apartment conversion in Hollywood runs $140,000 to $190,000 depending on whether you need a new footing, upgraded electrical service, or fire-rated separation from a neighboring property.
Detached Garage Flats
The flat-lot conversions between Melrose and Sunset are the most straightforward in Hollywood. These alleys give us clear access for materials and a dumpster without blocking your driveway. We replace the garage door with a wall that matches the home’s stucco, add a private entrance off the alley or side yard, and run new plumbing and electrical from the main house.
Hillside Garage Apartments
Once you climb into Beachwood Canyon or Nichols Canyon, the rules change. Sloped lots often mean the garage sits below grade or hangs off a retaining wall, and Los Angeles fire codes for Very High Fire Hazard Severity Zones require ignition-resistant siding and roofing. A hillside garage apartment conversion in Hollywood usually adds $25,000 to $45,000 over a flat-lot build, mostly in foundation and fire-safety materials like James Hardie siding.
Garage Conversion Permit in Hollywood
Garage Conversion Permit in Hollywood starts with one question our team asks before anything else: does the lot fall inside a Historic Preservation Overlay Zone? If your address sits in Spaulding Square, Whitley Heights, or another of Hollywood’s HPOZ districts, LADBS will route your permit through design review, and the reviewers will require period-appropriate stucco textures, window profiles, and rooflines that match the original 1920s or 1930s character. That’s not a problem if you know it upfront. It becomes a problem if a contractor demos first and asks later.
HPOZ Design Review Path
We pull the HPOZ map before quoting any Hollywood garage conversion. Inside a district, our drawings include the exact window mullion pattern, stucco color, and roof pitch the reviewing architect will look for, so the design review hearing is a formality, not a fight. Outside the district, permits move faster but still require structural, mechanical, and Title 24 energy compliance.
Open-Wall Code Upgrades
Every 1920s Hollywood garage we convert triggers the same conversation: once we open the walls, LADBS requires the work to meet current code. That means replacing cloth-wrapped wiring, adding shear wall where the old framing fails, and sometimes pouring a new footing where the slab has settled toward the alley. We write allowances for these items into your contract before we start, so a change order is a conversation, not a confrontation.

Written Change Orders Only
Nothing on our Hollywood jobs gets priced by surprise. When our techs find termite damage or a slab that moved, Ben writes the change order, you approve it in writing, and then we order materials. That’s the whole process. It’s why our Hollywood clients tell us they never felt out of control during the build.
Trusted Brands We Service in Hollywood
We work with the prefab and materials brands Hollywood homeowners research most, including Abodu, Cover, and James Hardie. For alley-served lots where a crane can’t reach, panelized systems like Abodu’s can be walked in piece by piece. For hillside fire zones, James Hardie fiber cement siding and trim give LADBS what it asks for without sacrificing the stucco look your Spanish Colonial home expects. Ben will walk you through what each brand does well on your specific lot, not what we prefer to sell. We keep common Hollywood permits and products stocked locally so material releases don’t stall your schedule.
Common Garage Conversion Contractor Problems We See in Hollywood Homes
- The HPOZ surprise. A quote was given without checking the historic overlay map, and after demo the design review board required new window types and a different roofline. We pull the map first, every time, and we stare at it with you at the kitchen table.
- 1920s wiring and framing. Cloth-wrapped wire, termite-damaged top plates, and undersized studs are standard in Hollywood garages from the 1920s and 1930s. Opening those walls and doing nothing is not an option once LADBS inspects, so we write those allowances into the contract on day one.
- Hillside fire-zone rules on flat-lot assumptions. Quotes written for flat Hollywood lots don’t account for Very High Fire Hazard Severity Zone siding, roofing, and venting requirements in Beachwood and Nichols Canyons. We quote the hills separately, with the fire code baked in.
- Settled slabs and alley drainage. Many Hollywood rear-alley garages have slabs that pitched toward the alley for decades, and water followed. A conversion that ignores drainage pushes water under your new floor later. We check the slope with a laser before we quote.

FAQs About Garage Conversion Contractor in Hollywood
Yes and no. If your garage sits inside Spaulding Square, Whitley Heights, or another Historic Preservation Overlay Zone, LADBS routes the permit through design review, which means period-correct windows, stucco, and rooflines. If your lot is outside the HPOZ boundaries, no design review is required. We check the map before quoting so there’s no ambiguity. Call (707) 383-5338 and Ben will check your address while you’re on the phone.
Cloth-wrapped aluminum wiring, termite-damaged top plates, sagging studs, and settled slabs are the four we see most in Hollywood’s 1920s and 1930s garages. In Spaulding Square, our tech once opened a 1926 detached garage and found all four, plus a slab that had dropped two inches toward the alley. We write allowances for these conditions into your contract before demo, so the discovery is already priced.
We use written allowances within the contract, and any work beyond those allowances gets a written change order with a line-item price. You approve it before we order materials or move a hammer. Nothing gets added to your bill that Ben hasn’t walked you through first. That’s our 365-Day Done Right Promise in practice, and it covers every Hollywood garage conversion we build.
Yes. Garages in Beachwood Canyon, Laurel Canyon, Nichols Canyon, and other hillside pockets mostly fall inside LA’s Very High Fire Hazard Severity Zone, which requires ignition-resistant or non-combustible siding, roofing, and venting. Flat-lot garages near Melrose or Santa Monica Boulevard don’t carry those requirements. We quote the hills with fire code built in, not as an afterthought.
We work with Abodu, Cover, Dvele, and use James Hardie fiber cement for hillside fire-zone exteriors. For rear-alley Hollywood lots where crane access is tight, Abodu’s panelized system often fits better than a full modular unit. Ben will walk you through what each brand adds to your specific lot and budget when you call (707) 383-5338.
