ADU in Burbank, CA
Accessory dwelling unit design and permitting in Burbank runs through two parallel systems that most homeowners never hear about until the project stalls: Burbank Water and Power’s inspection queue and Burbank Building’s separate permit track. A 1940s Magnolia Park bungalow with a 100-amp panel cannot support a second dwelling without coordination between both agencies, and the single most common delay on Burbank ADU jobs is a scheduling mismatch between those two desks. We design, permit, and build ADUs in Burbank under one contract at one written price. Call (971) 497-2402 for a written scope before any work begins.
Why Burbank Homes Are Different
Burbank’s residential flatlands were built fast between 1940 and 1965 to house Lockheed plant workers, and the housing stock still reflects that urgency: modest 6,000 to 7,500 square foot lots, single-story framing, detached one-car garages accessed from rear alleys, and original 100-amp electrical service that almost always requires a panel upgrade before any ADU can pull its own meter. Those rear alleys are a quiet advantage for detached garage conversions, since crews can stage materials and run utility trenches without tearing up the main yard.
The climate adds another layer. Burbank sits in the eastern San Fernando Valley’s thermal belt and records some of the highest summer temperatures in the LA Basin, regularly crossing 100°F in July and August. An ADU built to minimum Title 24 code with a flat or low-slope roof and undersized HVAC will be functionally unlivable here in summer. We size mechanical for actual Burbank peak loads, not state minimums. Hillside parcels abutting the Verdugo Mountains fall into Very High Fire Hazard Severity Zones, which trigger CAL FIRE Chapter 7A requirements for ignition-resistant siding, multi-pane windows, and ember-resistant vents on any new structure. On those lots, the material spec changes before the first drawing is complete.
Our Main Burbank Services
Two ADU types dominate the inquiries we receive from Burbank homeowners: detached garage conversions on those Lockheed-era alley lots, and new detached units in backyards with the space to go wider.
Garage Conversion ADU in Burbank
Most Magnolia Park and Victory-corridor garages were built as one-car structures in the 1940s and 1950s, with slab foundations that are frequently within range for a conversion without major structural work. The complication in Burbank is almost always electrical: the garage shares the main house’s 100-amp service, and BWP requires a separate service drop for the new unit, coordinated through the alley. We handle the panel upgrade, the BWP coordination, the permit set, and the construction under one contract so the designer and the builder cannot point at each other when something stalls. See Garage Conversion ADU in Burbank for full pricing and scope.
New Detached ADU in Burbank
Backyard lots in the flats south of Olive Avenue typically have enough depth for a 600 to 1,000 square foot detached unit, but Burbank’s locally-adopted setback interpretations for alley-facing parcels differ subtly from the state template, and getting the setback variance wrong at permit application means redoing drawings. Fire zone requirements on hillside parcels add further scope. We produce the full permit set, handle the variance if one is needed, and build to the drawings with a written photo record of every visit.

ADU Design & Permitting in Burbank
ADU design and permitting in Burbank is where most projects either get built correctly or quietly go wrong. The drawings are not a formality here: Burbank’s planning department enforces locally-adopted ADU design standards, and BWP issues its own permits on a parallel but unsynchronized track, so a permit set that does not account for both agencies in the right order gets rejected or delayed. A 1940s bungalow with original electrical service and an alley-fed garage needs drawings that name the panel upgrade path, the service drop location, and the fire-zone material spec before anyone files. That is the permit set we produce, and it is the core product of our ADU Design & Permitting service, not an afterthought.
Site Assessment
Signs you need it
Your lot slopes toward the Verdugo foothills, your garage sits within five feet of the alley property line, or your panel is original 100-amp and you don’t know whether BWP will require a new meter pull.
What it costs in Burbank
Site assessment documentation typically runs $800 to $2,500 in Burbank, depending on lot complexity and whether a topo survey is required for a hillside parcel.
How we do it
We measure the lot, verify the existing foundation depth, photograph every condition, and produce a written site report that names each constraint before a single drawing is started.
Permit Application
Signs you need it
You’ve had a drawing done but Burbank Building sent it back with redlines, or BWP told you the service drop needs to move and no one knows whose permit covers that.
What it costs in Burbank
Full permit application management runs $3,000 to $7,500 in Burbank, including BWP coordination, plan check responses, and inspection scheduling on both tracks.
How we do it
We file the complete permit set, respond to plan-check comments, coordinate BWP and Burbank Building scheduling, and hand you a permit-ready package with every agency sign-off in writing.
What ADU Design & Permitting Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Site assessment and topo survey | $800 - $2,500 |
| Full architectural and permit set | $12,000 - $35,000 |
| Permit application management | $3,000 - $7,500 |
Does Burbank require a separate electrical permit from BWP for an ADU?
Yes. BWP issues its own service and meter permits on a separate track from Burbank Building, and failing to file both in the right order is the most common delay on Burbank ADU projects. We file both tracks and schedule them together.
How long does Burbank plan check take for an ADU permit set?
Plan check typically runs 8 to 16 weeks in Burbank depending on comment volume and BWP queue position. A complete permit set filed with BWP coordination already documented moves noticeably faster than a partial set that triggers the same comments twice.
Junior ADU & Interior Conversion in Burbank
Junior ADUs and interior conversions turn existing square footage in a Burbank house into a rentable or family-occupied unit without adding a new structure. The typical candidate in Magnolia Park or south of Olive Avenue is a 1940s three-bedroom with a den, a finished garage space previously used as a workshop, or a large primary suite that can split into a JADU with a separate entrance. Burbank’s approvals for JADUs are generally faster than for detached units, but the electrical reality is the same: original 100-amp panels almost always need an upgrade before the new unit can pass inspection. Our Junior ADU & Interior Conversion service covers the drawing set, the BWP coordination, and the build under one contract.
Room-to-ADU Conversion
Signs you need it
You have a bonus room, den, or enclosed porch with its own exterior door, and you want it to function as an independent unit with cooking, bath, and separate metering.
What it costs in Burbank
Room-to-ADU conversions in Burbank typically run $90,000 to $180,000 all-in, depending on whether the existing space needs a new kitchen rough-in and separate electrical subpanel.
How we do it
We document the existing walls and electrical, draw the conversion to Burbank’s JADU standards, pull panel and permit work through BWP, and build with a written photo record at every visit.
Interior JADU
Signs you need it
Your primary suite is large enough to split, or you have an interior room adjacent to the garage that can become a JADU with its own entry and a compact kitchen.
What it costs in Burbank
An interior JADU in Burbank typically runs $65,000 to $130,000, with the higher end reflecting panel replacement and a new service drop through BWP.
How we do it
We design the separation to maintain egress and natural light, file the JADU permit set, handle BWP’s electrical coordination, and build to the approved drawings with fixed pricing.
What Junior ADU & Interior Conversion Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Interior JADU with compact kitchen | $65,000 - $130,000 |
| Room-to-ADU conversion with bath | $90,000 - $180,000 |
| Panel upgrade through BWP | $4,000 - $9,000 |
Does a JADU in Burbank need its own BWP meter?
Not always. Burbank allows some JADUs to share the main house service if the load calculation passes, but most 1940s panels fail that calc and require an upgrade or a subpanel. We run the load numbers during design so you know before filing.
Will a room-to-ADU conversion trigger a full rewire of the main house?
Rarely. Burbank Building asks for the new unit’s wiring to meet current code, but the existing house can generally remain unless the panel is overloaded. We scope the new work only, in writing, before construction starts.
ADU Site Prep & Utilities in Burbank
Site prep and utilities in Burbank is where the Lockheed-era housing stock shows its age most directly. The alley-fed lots in Magnolia Park were never designed for a second dwelling, so every detached ADU requires either a new electrical service drop through BWP or a panel upgrade at the main house, and often both. Trenching for plumbing laterals and gas line extensions through those rear alleys means coordinating with BWP on the same corridor where production companies along the Alameda Entertainment Corridor run their own service demands, so sequencing matters as much as the digging itself. Our ADU Site Prep & Utilities service handles every underground and overhead utility under the same written contract as the build.
Electrical Panel Upgrade
Signs you need it
Your main panel says 100 amps, you want an electric heat pump or induction cooktop in the new unit, or BWP has already flagged your service as undersized for a second meter.
What it costs in Burbank
Panel upgrades on Burbank homes typically run $4,000 to $9,000, including BWP service coordination and a new meter pull where the existing panel predates the current drop.
How we do it
We file the BWP service application, upgrade the panel and ground, pull the new service drop through BWP’s inspection queue, and document every step with photographs for your record.
Foundation & Grading
Signs you need it
Your backyard slopes more than a foot across the build area, the existing garage slab has settled or cracked along the alley edge, or the lot drains toward the main house.
What it costs in Burbank
Foundation and grading work in Burbank typically runs $12,000 to $35,000, with hillside Verdugo-adjacent lots at the higher end due to retaining and drainage requirements.
How we do it
We survey the grade, engineer the slab or stem-wall foundation to Burbank’s drainage standard, form and pour, and photograph the rebar before the concrete is placed so you have a permanent record of what is under the slab.
What ADU Site Prep & Utilities Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Electrical panel upgrade through BWP | $4,000 - $9,000 |
| Foundation and grading | $12,000 - $35,000 |
| Trenching and utility lateral installation | $4,000 - $15,000 |
Does BWP charge separately for a new meter on an ADU?
Yes. BWP has its own fee schedule for meter pulls, service drops, and inspection time, and those fees are billed separately from Burbank Building permits. We itemize every BWP fee in the written scope so there is no surprise line at the end.
Can I keep the existing garage slab for a conversion, or do I need new footings?
Often yes, if the slab is intact and at least 4 inches thick with no alley-side settlement. We verify slab depth and condition during site assessment and tell you in writing whether new footings are required or the existing slab can remain.

Costs in Burbank push higher when the lot sits in a Very High Fire Hazard Severity Zone requiring Chapter 7A materials, when the panel is original 100-amp and BWP requires a new service drop, or when a setback variance is needed for an alley-facing parcel. Every line above is a written range, not an estimate you will see revised at signing: our written price under Haven Standard Clause 1 locks the scope before any work begins.

FAQs About ADU in Burbank
Yes. Burbank Water and Power operates independently from Burbank Building, and every ADU with a new meter, service upgrade, or electrical panel change requires a separate BWP application and inspection. We file both tracks and schedule them together so the inspections do not stall each other.
Most Burbank neighborhoods do not have HOAs outside of a few planned developments in the hills and newer condo projects. Where an HOA does exist, California law limits its ability to prohibit ADUs, but design review may still apply. We check the HOA’s recorded rules during site assessment and flag any restrictions before you spend money on drawings.
Site assessment happens within a week of signing, and design typically takes six to ten weeks before filing. The Burbank plan check and BWP coordination adds eight to sixteen weeks, after which construction begins. We give you a written schedule at the start, and the Haven Standard holds the price fixed while the permits move.
