ADU in Burbank, CA
Junior ADU and interior conversion in Burbank typically runs $85,000-$165,000 all-in, while site prep and utility work adds $15,000-$45,000 depending on what the existing 1940s-1960s stock requires. We’re Ellery ADU Studio, and we’ve found Burbank’s post-war wood-frame homes on 6,000-7,000 sq ft lots create a predictable conversion path - until you hit the BWP utility queue or a Magnolia Park foundation that hasn’t been touched in ninety years. Call (213) 329-7167 and we’ll walk your property with a written price before any work starts, per Haven Standard Clause 1.
Why Burbank Homes Are Different
Burbank sits in the eastern San Fernando Valley where summer temperatures regularly top 100°F, so mechanical cooling isn’t optional in any new ADU - it’s a code and comfort reality. The proximity to the Verdugo Mountains puts portions of north and east Burbank in moderate-to-high fire hazard severity zones, which governs siting distances, ember-resistant venting, and exterior cladding choices under current California building code.
The housing stock tells its own story. Most lots hold 1940s-1960s post-war wood-frame stucco homes with detached two-car garages in the rear - the standard conversion target. But Magnolia Park’s 1920s-1940s Craftsman bungalows on smaller lots with mature trees and aging foundations demand extra pre-construction evaluation before design work begins. And Burbank is the only Valley city where we’re as likely to be designing a sound-isolated editing suite or writer’s room as a rental unit - Warner Bros., Disney, and dozens of production companies headquartered here mean entertainment-industry homeowners need professional-grade workspaces with acoustic treatments and high-amperage dedicated circuits that simply aren’t the default in adjacent Glendale or Studio City.
Then there’s BWP. Unlike surrounding Valley cities served by LADWP or SoCal Edison, Burbank runs its own municipal utility - Burbank Water and Power - so every electrical upgrade, sub-panel addition, and new utility meter runs through BWP’s separate fee schedule, capacity review, and inspection queue. Contractors who routinely work across LA County consistently underestimate timelines and utility connection costs on their first Burbank ADU job.
Our Main Burbank Services
Most Burbank homeowners start with one of these three services. Each has its own detailed page if you want deeper pricing and scope.
ADU Design & Permitting in Burbank
We produce the full permit set - architectural drawings, structural calculations, Title 24 energy compliance, and Burbank Planning & Building submission - as the core product, not an afterthought. For Burbank’s 1940s-1960s stock, we verify original foundation type and roof framing early, since both appear in every Burbank plan check. ADU Design & Permitting in Burbank
Garage Conversion ADU in Burbank
The detached two-car garage behind most Burbank homes is the fastest path to rentable square footage, but slab thickness, ceiling height, and BWP electrical capacity determine whether the existing structure converts or needs partial rebuild. We measure all three before design starts. Garage Conversion ADU in Burbank
New Detached ADU in Burbank
When the existing garage won’t convert or when you want a standalone unit, new detached ADUs in Burbank face fire-hazard zone setbacks, BWP trenching for electrical service, and the city’s design-review process for certain lot configurations. We coordinate all three in a single contract. New Detached ADU in Burbank

Before
AfterJunior ADU & Interior Conversion in Burbank
Junior ADU and interior conversion in Burbank solves the problem of adding rentable square footage without touching the rear yard or waiting through a full detached ADU permit cycle. For the 1940s-1960s homes that dominate Burbank’s R-1 lots, this often means converting underused interior space - a basement, an attached room, or a section of the main house - into a self-contained unit with its own kitchen and exterior door. The entertainment-industry demand profile here also pushes many conversions toward professional workspace: sound-isolated editing suites, writer’s rooms, and voice-over booths that need acoustic treatment and dedicated circuits beyond standard residential specs. We handle the design, permit set, and construction under one contract with one written price. Junior ADU & Interior Conversion
Room-to-ADU Conversion
Signs you need it
You have a 250-400 sq ft attached room - former den, unused bedroom, or converted porch - with direct exterior access potential and a main panel that can accept a sub-feed.
What it costs in Burbank
Room-to-ADU conversion in Burbank typically runs $85,000-$140,000 all-in, including the permit set, fire-rated separation, mini-split installation for 100°F summers, and BWP electrical coordination.
How we do it
We verify existing framing and insulation, design the fire-rated separation wall per Burbank Building code, run BWP load calculations for the added electrical demand, and build to the permitted drawings with a documented photo record on every visit.
Interior JADU
Signs you need it
You want the fastest permit path under state law: a Junior ADU up to 500 sq ft inside your existing footprint, sharing bathroom and mechanical systems with the main house.
What it costs in Burbank
Interior JADU in Burbank typically runs $65,000-$95,000 all-in, with savings from shared systems offset by BWP electrical upgrade costs and the acoustic treatments many Burbank clients request.
How we do it
We identify the optimal interior zone for separation, design the efficient kitchenette and exterior door placement, produce the JADU-specific permit set for Burbank’s expedited review, and build with the 365-Day Done Right Promise in writing.
What Junior ADU & Interior Conversion Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Room-to-ADU conversion (all-in) | $85,000 - $140,000 |
| Interior JADU (all-in) | $65,000 - $95,000 |
| Acoustic/sound-isolation upgrade (entertainment workspace) | $8,000 - $18,000 |
Can a Junior ADU share a bathroom with the main house?
Yes, under California state law a JADU up to 500 sq ft may share bathroom and mechanical systems with the main residence, which reduces both construction cost and permit complexity compared to a full ADU. Call (213) 329-7167 for an exact quote - estimates are free.
Do Burbank’s fire hazard zones affect interior conversions?
Interior JADUs and room conversions are generally exempt from exterior fire-hazard setback rules, but if your project adds any new exterior door, window, or modifies egress paths, ember-resistant venting requirements may apply to the new opening - we verify this in the permit set before construction starts.
ADU Site Prep & Utilities in Burbank
ADU site prep and utilities in Burbank means dealing with 1940s-1960s infrastructure that was never sized for a second dwelling: undersized electrical panels, clay sewer laterals, and gas lines that terminate at the main house. The BWP factor - Burbank’s independent municipal utility - adds a coordination layer that LA County contractors often miss on their first job here, with separate fee schedules, capacity reviews, and inspection queues that can extend timelines by weeks if not planned from the permit set forward. We handle BWP submission, trenching, and final hookup as part of our single-contract scope. ADU Site Prep & Utilities
Electrical Panel Upgrade
Signs you need it
Your main panel is 100 amps or less, or the label shows no spare breaker spaces for an ADU sub-panel feed.
What it costs in Burbank
Electrical panel upgrade in Burbank typically runs $4,500-$8,500 including BWP permit, new 200-amp service equipment, and coordination with BWP’s inspection queue.
How we do it
We verify BWP’s available transformer capacity for your address, specify the new panel and grounding system, pull the BWP permit, and schedule BWP inspection before rough-in.
Plumbing Lateral
Signs you need it
Your home has original clay or cast-iron sewer lateral from the 1950s-1960s, or the city record shows no separate cleanout for a rear ADU connection.
What it costs in Burbank
Plumbing lateral replacement or extension in Burbank typically runs $6,000-$14,000 depending on trench length, pavement restoration, and whether Burbank Public Works requires traffic control for street crossing.
How we do it
We camera the existing line, design the new lateral route to the ADU location, coordinate Burbank Public Works for any street cut, and pressure-test before backfill with documented photo record.
What ADU Site Prep & Utilities Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Electrical panel upgrade (200-amp, BWP coordinated) | $4,500 - $8,500 |
| Plumbing lateral replacement/extension | $6,000 - $14,000 |
| Site grading and compacted base (new detached ADU pad) | $5,000 - $12,000 |
Does BWP require a separate meter for an ADU?
BWP generally allows a sub-meter arrangement for ADUs under 750 sq ft, but requires a separate service lateral and meter for larger units or when the main panel cannot accommodate the calculated load - we determine this during permit set production and include the finding in your written quote.
How long does BWP take to approve an electrical upgrade?
BWP’s capacity review and electrical permit approval typically takes 2-4 weeks, which we build into the project schedule from the start - never as a surprise delay after construction begins. Call (213) 329-7167 to discuss your specific timeline.

What Burbank Customers Say
"The rental income has covered the payment since the second month. They were realistic about the numbers rather than optimistic."
- Odette N."Garage conversion finished on the drawings and close to the schedule. They were honest that the sewer connection was the unknown, and it was."
- Arjun D."They walked us through setbacks and utility capacity before we paid anything, and told us one of our two options was not going to get approved."
- Mireille T.
