Garage Conversion ADU in Burbank - Plans, Permits & Build, One Fixed Price

Fast, Reliable Garage Conversion ADU Across Burbank

A garage conversion ADU in Burbank typically runs $215,000-$385,000 all-in, drawings through final inspection, depending on whether you’re converting an attached garage, a detached alley-load garage, or partitioning an existing oversized garage into a JADU plus storage. The two variables that move the number most in Burbank are your electrical service capacity and the condition of the original garage slab and framing, both of which we inspect and price in writing before you commit to anything. If you own a 1940s-1960s Burbank home in Magnolia Park, the Victory corridor, or south of Olive, you already know the house has character. The garage usually has questions.

Nadia Ellery founded Ellery ADU Studio in 2015, the same year California’s ADU permitting landscape shifted, and she built the practice around one idea: the permit set is the product. We design, permit, and build garage conversions under a single contract at a single written price. No designer blaming the builder, no builder blaming the designer. That matters more in Burbank than almost anywhere else in the Valley, because the city’s utility and building departments run on separate tracks, and the coordination between them is where cheap quotes quietly die.

Why Ellery ADU Studio Is Burbank’s Preferred Garage Conversion ADU Company

We have designed, permitted, and built 900+ ADUs since 2015, and a meaningful share of those are garage conversions on lots that look like yours: rear alleys, detached one-car garages, 6,000-7,500 sq ft parcels, 100-amp panels that predate the Reagan administration. Our crews work Burbank regularly. We know the Burbank Water and Power fee schedule, we know how Burbank Building’s local ADU amendments differ from the state template, and we know that a Magnolia Park detached garage off the rear alley has a different inspection sequence than a hillside property above Kenneth Road in a Very High Fire Hazard Severity Zone.

Every Garage Conversion ADU we take on starts the same way: we open the scope, not just the brochure. We look at the panel, the slab, the sill plates, the roof framing, and the alley access before we put a number on paper. Under Haven Standard Clause 1, that number is written before any work starts. Under Clause 5, it doesn’t move unless you approve a written change order. Burbank homeowners hire us because we document what we find, not what we felt. Every visit includes a photo record. Every permit pull is sequenced with BWP. Every promise is in writing, including the 365-Day Done Right Promise: if the finished ADU is not built to the permitted drawings, we make it right.

If you already have a written estimate from another contractor or design firm, bring it to us. We’ll give you a Free Second Opinion and show you line by line what’s real, what’s missing, and what’s going to hit you at rough-in.

Our Garage Conversion ADU Services in Burbank

We offer the full range of Burbank garage conversion scopes, from attached garage-to-studio conversions to detached alley-load ADUs with rear setbacks that only Burbank interprets the way it does. Here’s what we build most often in Burbank.

Attached Garage Conversion

Attached garage conversions in Burbank typically run $185,000-$290,000, and the dominant cost drivers are the fire separation assembly between the garage and the house, the required panel upgrade, and reworking the front elevation so the house doesn’t look like a garage with a door swapped for a window. Burbank Building’s local amendments to the state ADU template require specific fire-rated details at the dwelling-unit separation wall, and we draw those into the permit set from day one, not as a field fix. Attached conversions on Burbank’s 1940s-era bungalows almost always reveal the same thing: a slab poured without rebar and a 4-inch stem wall that needs retrofit anchors for seismic compliance once the garage is conditioned space.

Detached Garage Conversion

Detached garage conversions in Burbank typically run $240,000-$385,000 when the garage is off the rear alley, which most of them are in Magnolia Park and the blocks south of Olive Avenue. Those numbers include the BWP meter pull and a new 200-amp service drop routed to the ADU separately from the main house, which is the single most mis-scheduled item on Burbank ADU jobs. The alley access itself is logistically clean: materials go in from the rear, the house stays livable, and we don’t have to run a Bobcat through your front yard. What is not clean is the coordination. BWP issues its own permit on its own inspection queue. Burbank Building issues theirs. If the two aren’t sequenced, you end up with a drywalled unit that can’t be energized for two to three weeks. We sequence both before demolition starts.

Garage JADU

A Garage JADU, or Junior ADU, in Burbank typically runs $120,000-$190,000 when it’s built inside the footprint of an existing oversized garage, with a separate entrance, a kitchenette, and its own bathroom. This is the fastest path to a legal rental unit in Burbank because JADUs have a lighter permit track and fewer parking requirements than a full ADU. The catch is the utility metering: BWP requires a separate meter or a sub-metering agreement for a JADU with independent occupancy, and that’s another item that doesn’t show up in a generic quote. We price it on the first pass, before you sign anything.

Carport Conversion

Carport conversions in Burbank are rarer, but we do them where the carport is attached to the house or built against a shared lot line. The scope usually involves pouring a new slab or leveling the existing pad, framing the open sides, and upgrading the carport’s single circuit to a full sub-panel. These tend to run $165,000-$240,000 depending on what’s under the pad and whether Burbank’s setback interpretations require a variance. We tell you on inspection day whether the carport can be converted as-of-right or whether you’ll need a planning review. That’s the kind of thing you want to know before you buy the windows.

Trusted Brands We Service in Burbank

When a Burbank garage conversion calls for a prefab or modular shell, we specify and coordinate systems from Abodu, Cover, and Dvele, alongside conventional stick-built scopes. We also specify James Hardie siding and trim on nearly every exterior we touch in Burbank because it holds paint in the Valley’s UV and because it meets the Chapter 7A ignition-resistant requirements on hillside lots without looking like a firehouse. We don’t stock a warehouse full of brand inventory. We coordinate the manufacturer’s scope inside the same single contract and written price, so the prefab shell and the site work don’t become two different budgets managed by two different people who don’t return each other’s calls.

Common Garage Conversion ADU Problems We See in Burbank Homes

Burbank’s housing stock is specific: post-WWII single-family homes built for Lockheed plant workers, mostly 1940s-1960s, on modest lots with detached one-car garages off rear alleys. That specificity produces predictable failure modes. Here’s what we most often find when we open a Burbank garage for conversion:

• Knob-and-tube wiring spliced into modern romex. We see this constantly in Magnolia Park and the Victory corridor. The house was rewired at some point, but the garage was skipped, and someone made an illegal splice to make the garage door opener work. Once the garage becomes habitable space, BWP and Burbank Building both require the splice-out and a compliant feeder. This is not optional, and it’s not cheap. We find it in inspection, not at rough-in.
• Rotted sill plates from decades of sprinkler overspray. Burbank’s dry summers mean sprinklers run year-round, and the spray pattern on a 1950s detached garage usually hits the base of the wall at the alley side. The sill plate rots, the stucco hides it, and the framer doesn’t find it until the wall is open. We price sill replacement as a written allowance in the contract, with a range, not a surprise.
• A 100-amp main panel that can’t carry an ADU. Almost every Burbank garage conversion on a pre-1970 lot starts with a panel upgrade to 200 amps, and because Burbank is served by BWP, not LADWP or SoCal Edison, the fee schedule, meter pull, and inspection queue are BWP’s own. Neighboring contractors who work Glendale or North Hollywood all week frequently mis-time this. We don’t, because Burbank is where our crews work most often.
• Alley-side service drops that BWP treats as a separate permit. The detached garage off the rear alley often has its own service drop, and BWP permits it separately from Burbank Building’s structural and electrical permits. A contractor who sequences everything through Burbank Building and treats BWP as an afterthought produces a finished ADU that can’t be powered for weeks. We’ve watched it happen. We schedule BWP before the insulation goes in, not after the paint dries.

On a Magnolia Park lot with a 1948 detached garage off the rear alley, we opened the walls to find knob-and-tube wiring spliced into romex and a sill plate rotted from decades of sprinkler overspray. Our tech wrote a change order for a BWP 200-amp panel upgrade, replaced the damaged framing with pressure-treated lumber, and installed a James Hardie rainscreen before the inspector arrived, so the surprise didn’t stall the finish. That’s how a change order is supposed to work: identified, priced, approved in writing, then built. Not discovered at final inspection with the homeowner holding the invoice.
