Fast, Reliable New Detached ADU Across Burbank
A new detached ADU in Burbank typically runs $180,000-$340,000 all-in, from permit set through final inspection, depending on size, site conditions, and whether you go custom-built or prefab. Most Burbank projects take 10-16 months from signed contract to move-in, with the two biggest variables being BWP service coordination and plan-check review at Burbank Building & Safety. We’ve designed and built detached units throughout Magnolia Park, the Verdugo foothills, and the Victory-corridor neighborhoods, and we know exactly where Burbank’s process diverges from what generic guides describe. Call (971) 497-2402 for a written price before any work begins.
Why Ellery ADU Studio Is Burbank’s Preferred New Detached ADU Company
Ellery ADU Studio has operated as a design-build practice since 2015, the year California’s ADU permitting landscape shifted. We’ve completed 900+ ADUs across the LA metro, and Burbank jobs make up a meaningful share of that number, because the city’s two-track permitting system rewards firms that understand it. Homeowners in Magnolia Park and the flats south of Olive Avenue come to us after reading about Burbank-specific inspection conflicts, and they stay because we document the sequence in writing before we ever pull a permit.
Our crews and technicians are background-checked and uniformed, and our license number appears on every page we send you. But the thing Burbank clients mention most is the predictability: under Haven Standard Clause 1, you get a written price before work starts, and under Clause 5 (No Surprises), the scope is locked at signing. No door-side upsells. No scope creep. A live person answers calls 24/7 at Ellery, and we offer a Free Second Opinion on any written estimate you already have in hand.
Nadia Ellery leads the studio, and she still reviews every Burbank permit set personally before it goes to the city. That matters in a city where a plan-check rejection after structural design is already paid for is a real and avoidable cost. Call (971) 497-2402 and ask for a written quote. You’ll get one.
Our New Detached ADU Services in Burbank
Custom Built ADU
A custom detached unit in Burbank lets you design around your specific lot, whether that’s an alley-facing Magnolia Park parcel with a rear garage you’re replacing, or a wider lot in the Victory corridor where you want a two-bedroom with a separate entrance and a real yard buffer. Custom builds in Burbank run $220,000-$340,000, and we produce a full permit set with architectural drawings, structural calcs, Title 24 energy compliance, and BWP service specifications before we quote the job. That’s the same document set Burbank Building & Safety reviews, so you see exactly what you’re paying for.
Prefab ADU Installation
Prefab and modular systems can shorten a Burbank build meaningfully, but the utility coordination doesn’t change. We specify and coordinate systems from Abodu, Cover, and Dvele within our single contract, and we handle the BWP panel upgrade, service drop, and meter sign-off as part of the same scope. Prefab units on flatland Burbank lots typically run $180,000-$260,000 installed, though hillside parcels near the Verdugos trigger Chapter 7A requirements that push prefab pricing up.
Modular ADU
Modular construction works well on Burbank’s 6,000-7,500 sq ft flatland lots, where crane access from the street or rear alley is usually straightforward. We handle the site prep, foundation, utility trenching, and BWP coordination while the modules are built off-site. A modular detached ADU in Burbank typically lands between $190,000 and $280,000, and the time saved is in the framing phase, not the permit phase. Plan smart, and the module delivery aligns with your inspections.
Studio ADU
Studio detached ADUs are the most quoted unit type in Burbank, and the entry point for most flatland homeowners. A 450-600 sq ft studio on a Magnolia Park or Victory-corridor lot runs $180,000-$225,000, including the panel upgrade most Burbank homes need. If the unit is for a renter, we size the HVAC for Burbank’s summer thermal belt, where 100°F+ days are routine, because a code-minimum unit with a flat roof is functionally unliveable by July.

Trusted Brands We Service in Burbank
We specify and install systems from Abodu, Cover, and Dvele, and we coordinate James Hardie siding where fire-zone or durability requirements apply, which is common on Burbank hillside parcels near the Verdugos. Because we work these vendor relationships continuously, our Burbank clients don’t wait on factory lead times the way a one-off buyer would. The material order, the permit set, and the construction schedule sit in the same document, so the prefab delivery doesn’t arrive before the BWP meter is approved. Call (971) 497-2402 and we’ll walk you through which system fits your lot.
Common New Detached ADU Problems We See in Burbank Homes
- The BWP and city inspection timeline falls out of sync. Burbank Building & Safety and Burbank Water and Power issue separate permits on parallel but unsynchronized tracks. If the panel upgrade sits in BWP’s queue while your ADU is ready for drywall sign-off, the project stalls. We schedule the BWP disconnect/reconnect and the city’s rough and final inspections in the same window, so the shell doesn’t sit unpowered for weeks.
- Hillside lots fail the fire-hazard check after the shell is up. Parcels abutting the Verdugo Mountains fall into Very High Fire Hazard Severity Zones, which trigger CAL FIRE Chapter 7A material requirements: ignition-resistant siding, multi-pane windows, ember-resistant vents. Builders who skip these to save cost end up doing a full material swap after the shell is framed. We scope Chapter 7A compliance in the written quote, before any work starts.
- Alley-facing setbacks are read wrong. Magnolia Park’s detached one-car garages sit on alleys, and Burbank’s locally adopted ADU design standards interpret alley-facing setbacks differently than the county template many contractors default to. A plan that passes in unincorporated LA County can be rejected in Burbank after structural design is already paid for. We file to Burbank’s standard the first time.
- The 100-amp panel can’t feed a second unit. The post-WWII Lockheed-era homes in the Burbank flats almost universally run original 100-amp service. A new detached ADU with a kitchen, HVAC, and laundry requires an upgrade, usually to 200 amps, and that upgrade is a BWP service change, not a city permit item. We include the panel math, the BWP fee schedule, and the alley-side service drop coordination in the quoted scope.

FAQs - New Detached ADU in Burbank
Burbank Building & Safety and Burbank Water and Power issue separate permits on parallel tracks, so a panel upgrade can sit in BWP’s inspection queue while the city is ready for drywall sign-off. The ADU gets framed and then sits unpowered for weeks. We schedule the BWP disconnect/reconnect and the city’s rough and final inspections in the same two-day window, which is the only reliable way to keep the job from stalling. If you already have a written estimate, call (971) 497-2402 for a Free Second Opinion on whether the utility sequence is scoped correctly.
Yes, if the parcel falls within a Very High Fire Hazard Severity Zone, which most Verdugo-adjacent hillside lots do. The city enforces CAL FIRE Chapter 7A material requirements: ignition-resistant siding, multi-pane windows, and ember-resistant vents. We scope these materials in the written quote from the start, so there’s no material swap after the shell is up. Call (971) 497-2402 and ask us to check your parcel’s fire-zone status before you pay for structural design.
Alley lots in Magnolia Park and the surrounding flats have separate alley-side service drops, which means the BWP service change and the meter feed run from the alley, not the street, and BWP treats that alley-side drop as its own coordination item, separate from the main house meter. Front-facing lots run the service from the street, which is more straightforward but still requires BWP’s own inspection and sign-off. We coordinate the alley-side mast, the trenching, and the BWP queue as part of the quoted scope, because a failed coordination between BWP and Burbank Building is the single most common delay on Burbank ADU jobs. Call (971) 497-2402 for an exact quote on your lot’s service path.
Rarely. A detached unit with a kitchen, HVAC, and laundry pulls enough load that a 100-amp panel can’t feed both structures safely. Most Burbank flatland homes, built in the 1940s-1960s for Lockheed plant workers, still run original 100-amp service, and the upgrade to 200 amps is a BWP service change, not a city permit item. We include the panel math, the BWP fee schedule, and the service-drop coordination in the written quote, so you’re not surprised by a $6,000-$12,000 line item later. Call (971) 497-2402 to get your panel evaluated as part of the free estimate.
Burbank’s planning department enforces a locally adopted alley-facing setback interpretation that differs from the state template and from what Glendale and unincorporated LA County accept. On a Magnolia Park alley lot, the rear setback is measured from the alley right-of-way, not the property line, which can shrink your buildable footprint by a few feet. That difference is enough to force a design change if the plan was drawn to county standards. We file to Burbank’s standard the first time, so the plan check doesn’t reject your structural drawings after you’ve already paid for them. Call (971) 497-2402 and we’ll tell you what fits on your specific lot.
