Fast, Reliable Garage Conversion ADU Across Burbank
A garage conversion ADU in Burbank typically runs $85,000-$165,000 all-in, from measured drawings through final inspection, depending on whether your garage is attached, detached, or currently a carport. Most Burbank homeowners we work with in the 91501, 91504, and 91505 zip codes are converting 1940s-1960s ranch garages into rental units or in-law suites, and they’re surprised by how much Burbank’s independent charter-city status changes the permit path compared to LA City jobs. We’re Burbank-familiar: our design-build crews coordinate directly with Burbank Planning, Burbank Building & Safety, and BWP - not LADWP - so your utility upgrade doesn’t sit in the wrong queue for three weeks. Call (424) 551-7706 to schedule your free estimate. We’ll bring a written price, not a callback promise.
Why Ellery ADU Studio Los Angeles Is Burbank’s Preferred Garage Conversion ADU Company
Our Burbank ADU Design & Permitting team has designed, permitted, and built garage conversion ADUs across the flat grid south of SR-134, from the Magnolia Park bungalows near North Keystone Street to the hillside parcels edging the Verdugo Mountains. Our 900+ ADU portfolio since 2015 includes enough Burbank jobs that we know the difference between a standard plan check and the extended review Burbank Building & Safety assigns to hillside-adjacent lots.
Burbank homeowners leave reviews mentioning the same thing: we show up with the permit set already in progress, not a handshake and a “we’ll figure it out.” Our documented photo record - every visit, every wall opened - means you see the cloth-wrapped wiring or failed slab-edge waterproofing before we price the fix, not after we’ve started demolition.
Response time to Burbank is same-day for initial consultations. Scheduling and permit coordination run from our Los Angeles office, but the crew that measures your garage and the inspector who walks the final are Burbank-local. That matters when your panel upgrade is sitting in BWP’s queue and you need someone who knows the scheduler’s name.
Our license number appears on every page, every contract, and every permit application. Background-checked, uniformed crews. The Haven Standard in writing before you sign. That’s the baseline.
Our Garage Conversion ADU Services in Burbank
Attached Garage Conversion
The attached garage is the most common conversion we do in Burbank, especially in the postwar ranch stock between Magnolia Boulevard and Alameda Avenue. These garages share a wall with the house, which simplifies utility routing but complicates fire separation and sound attenuation under Burbank Building & Safety’s interpretation of the California Building Code. We handle the permit set, the Title 24 energy calculations for Valley heat, and the BWP service upgrade if your 100-amp panel can’t handle the additional load. Typical range in Burbank: $95,000-$140,000.
Detached Garage Conversion
Detached garages on Burbank’s 6,000-7,500 sq ft lots are tighter fits - setback rules here are interpreted by Burbank’s Planning Division, not LA’s, and we’ve seen contractors miss the side-yard clearances that trigger a variance. We survey the envelope before design starts, price the foundation and utility trenching in the written contract, and coordinate the detached ADU’s separate meter or house-meter sub-panel through BWP. Typical range: $110,000-$165,000.
Garage JADU
A Junior ADU conversion keeps the garage footprint under 500 sq ft and requires owner-occupancy of either the main house or the JADU - a fit for Burbank homeowners who want rental income without the full ADU infrastructure cost. Burbank’s Planning Division processes JADUs under a streamlined checklist, but we’ve seen applications stall when the owner-occupancy affidavit is missing or the parking replacement plan doesn’t meet Burbank’s specific off-street requirements. We prepare the full package: floor plan, elevations, electrical load calc, and the BWP coordination letter if needed. Typical range: $85,000-$120,000.
Carport Conversion
Carport conversions in Burbank face a specific hurdle: many postwar carports were slab-on-grade with no foundation depth for enclosed walls, and Burbank Building & Safety requires frost-depth footings or engineered slab reinforcement for habitable space. We assess the existing slab in the first site visit, include the foundation line item in the written quote, and design the enclosure to meet Burbank’s wind and seismic criteria. Typical range: $90,000-$135,000.
Garage Partition & Bathroom Add
Some Burbank homeowners want to keep half the garage for storage and convert the other half to a studio or bathroom-equipped workspace. This triggers Burbank’s minimum ceiling height rules (7’6″ for habitable space) and often requires re-grading the slab for proper drainage to the new bathroom. We model both halves in the permit set so there’s no ambiguity about what stays garage and what becomes living space.

Trusted Brands We Service in Burbank
Ellery ADU Studio specifies and coordinates prefab and modular systems from Abodu, Cover, and Dvele within the same single-contract design-build model we use for stick-built conversions. For Burbank homeowners who want a faster path to permit - especially on tight lots where custom framing adds weeks - we can integrate a Cover or Abodu unit into a garage-replacement or partial-conversion scope, with James Hardie siding specified for fire-resistance compliance on hillside-adjacent parcels. Every system is priced in writing before work starts, per Haven Standard Clause 1, and coordinated through Burbank’s permit process, not LA’s.
Common Garage Conversion ADU Problems We See in Burbank Homes
- Original 100-amp panels with cloth-wrapped wiring. We open garage walls on 1950s Burbank ranches and find NM cable from before grounded outlets were standard. The panel can’t handle ADU loads, and BWP’s upgrade queue adds 3-5 weeks. We identify this in pre-demo inspection and write the upgrade into the contract as a line item with a fixed allowance.
- Failed slab-edge waterproofing. Decades of Valley heat cycling crack garage slab edges, letting moisture wick into framing. Burbank’s inspection sequence requires us to show dry conditions before insulation and drywall. We test with moisture meters during demo and price remediation - epoxy injection, perimeter drain, or slab replacement - in writing before proceeding.
- Assuming LA City rules apply. Contractors new to Burbank submit ADU plans through LA’s portal, pay the wrong fees, and wonder why the permit is rejected. Burbank is its own charter city. We file directly with Burbank Planning, pay Burbank’s fee schedule, and schedule Burbank Building & Safety inspections - a separate sequence that adds time if you don’t know the order.
- Undersized ventilation for Valley heat. Burbank’s inland heat pocket hits 95-105°F in July and August. A garage converted without mechanical ventilation and proper insulation fails Title 24 and creates uninhabitable space. We size mini-split systems and HRV/ERV units for the actual load, not the rule-of-thumb, and we document the calc in the permit set.
Pricing for Garage Conversion ADU in Burbank, CA
| Service | Typical Range (Burbank) |
|---|---|
| Attached Garage Conversion | $95,000 - $140,000 |
| Detached Garage Conversion | $110,000 - $165,000 |
| Garage JADU | $85,000 - $120,000 |

| Foundation Repair/Replacement Allowance | $4,000 - $12,000 |
These ranges are all-in: measured as-builts, permit set, plan check fees, construction, and final inspection. What moves the number is what we find when walls open - which is why Haven Standard Clause 5 (No Surprises) locks the scope at signing and requires any additional work to be priced and approved in writing before we touch it. On that 1951 ranch off North Keystone Street in Magnolia Park, our crew opened the attached garage walls to find cloth-wrapped wiring feeding an original 100-amp panel and decades of failed slab-edge waterproofing. We upgraded the service through BWP’s queue, wrote a framing and wiring allowance into the contract before demo, and priced the extra shear and vent work in writing - the homeowner approved the change order before we touched a stud.

FAQs - Garage Conversion ADU in Burbank
It can share the main house meter in most cases, but Burbank Water and Power requires a load calculation proving the existing service can handle the ADU demand. If your home has an original 100-amp panel - common in Burbank’s 1940s-1960s stock - BWP will require a service upgrade to 200 amps, which runs through BWP’s separate scheduling queue and adds 3-5 weeks. We run the load calc during our first site visit and include the upgrade line item in your written quote if needed. Call (424) 551-7706 for an exact assessment - estimates are free.
An electric water heater, mini-split HVAC, kitchen appliances, and laundry circuits combined typically exceed the spare capacity of a 100-amp panel. BWP’s interconnection rules, not LADWP’s, govern the threshold. We model every circuit in the permit set and submit the load letter to BWP with the building permit application, so the upgrade is queued before construction starts, not discovered mid-project. Call (424) 551-7706 and we’ll check your panel size on the first visit.
Only if your parcel is mapped in the Verdugo foothills zone - roughly north of Glenoaks Boulevard and east of Buena Vista Street. Those parcels require ember-resistant construction, automatic sprinkler systems, and extended setbacks that Burbank Building & Safety enforces beyond the base code. We check the Cal Fire map and Burbank’s local hazard overlay during preliminary design and price the fire-resistive materials and sprinkler scope in the written contract. Call (424) 551-7706 to confirm your parcel’s status.
We expect it. Our contracts include a written allowance for common conditions in Burbank’s housing stock - cloth-wrapped wiring, ungrounded outlets, slab-edge moisture intrusion - based on what we find during pre-demo inspection. If demolition reveals worse damage than estimated, Haven Standard Clause 5 requires us to stop, photograph, price the fix, and obtain your written approval before proceeding. No door-side upsells. The photo record goes to you same-day. Call (424) 551-7706 to review how allowances work in our contracts.
Yes, if the converted space stays under 500 sq ft and you maintain owner-occupancy of either the main house or the JADU. Burbank’s Planning Division processes JADUs on a streamlined checklist, but applications stall when the owner-occupancy affidavit or parking replacement plan is incomplete. We prepare the full JADU package - floor plan, elevations, load calc, and BWP coordination - and file it correctly the first time. A JADU typically costs $85,000-$120,000 in Burbank versus $95,000-$140,000 for a full attached ADU. Call (424) 551-7706 to see which path fits your property and goals.
