ADU in Burbank, CA
Junior ADU and interior conversion in Burbank typically runs $85,000-$165,000 all-in, drawings through final inspection, while site prep and utility work adds $15,000-$55,000 depending on whether your existing panel and plumbing laterals can handle the load. Most Burbank homes in the Rancho, McCambridge, and Magnolia Park areas were built in the 1940s-1960s with sub-100-amp electrical panels and galvanized supply lines that must be upgraded before any ADU can pass occupancy. Because Burbank routes all electrical service through its own municipal utility, Burbank Water and Power, the interconnection workflow differs from SCE or LADWP territory and routinely trips up teams who don’t know the local sequence.

Why Burbank Homes Are Different
Burbank’s residential flatlands sit on 6,000-7,500 sq ft lots packed with post-WWII ranch-style homes and California bungalows, most with detached one- or two-car garages from the same era. That housing stock makes garage conversion ADUs the dominant project type, but it also means original galvanized plumbing, uninsulated walls, and electrical panels that cannot support a second dwelling unit without upgrade.
The eastern San Fernando Valley floor location pushes summer afternoons past 108°F during inland heat events, so mini-split sizing is not optional for rentable units. Properties near the Verdugo Mountains edge fall within a High Fire Hazard Severity Zone, triggering fire-resistive construction and defensible-space requirements that raise detached ADU costs for those parcels. Every electrical upgrade routes through BWP, with its own fee schedule, inspection cadence, and account-opening requirements separate from city building inspections.
Our Main Burbank Services
Most Burbank homeowners start with one of these three project types, each with its own dedicated page and local pricing.
ADU Design & Permitting in Burbank
We produce the full permit set, structural calculations, and BWP coordination documents as a single deliverable under one contract. Because we handle both design and build, there’s no designer-versus-builder gap when the city requests revisions. ADU Design & Permitting in Burbank covers every phase from feasibility study through certificate of occupancy.
Garage Conversion ADU in Burbank
Converting a 1940s-1960s detached garage in the Rancho or Magnolia Park neighborhoods means assessing slab thickness, ceiling height, and whether the existing foundation meets current code for habitable space. We quote the full scope, including panel upgrades and BWP meter sets, in one written price before work starts. Garage Conversion ADU in Burbank details the complete process.
New Detached ADU in Burbank
Building new on a Burbank lot requires navigating setback rules, fire-zone requirements for hillside parcels, and BWP service extensions that can add weeks if not sequenced correctly with the building permit. Our permit set includes the electrical service coordination documents from day one. New Detached ADU in Burbank explains the full timeline and cost structure.

Junior ADU & Interior Conversion in Burbank
Junior ADU and interior conversion in Burbank solves a specific problem for homeowners who need rental income or family housing but lack the budget or lot space for a detached unit. The 1940s-1960s housing stock in neighborhoods like the Rancho and McCambridge areas offers ideal candidates: spare bedrooms, underused basements, and above-garage spaces that can become independent dwelling units without expanding the building footprint. Because these projects work within existing envelopes, they avoid the fire-zone complications and setback battles of hillside detached ADUs, though they still require BWP electrical upgrades and full permit sets. Junior ADU & Interior Conversion covers our full approach to these projects.
Room-to-ADU Conversion
Signs you need it
You have a 200+ sq ft spare bedroom or den with direct exterior access and want a self-contained rental unit without building outward.
What it costs in Burbank
Room-to-ADU conversions in Burbank typically run $85,000-$140,000 all-in, including the required kitchenette, full bath, separate entrance, and BWP electrical upgrade.
How we do it
We measure existing conditions, produce the permit set with fire-separation details, coordinate the BWP panel upgrade, and build to the drawings under our single contract.
Interior JADU
Signs you need it
You need a compact, lower-cost unit inside your existing home for family or rental income, with the owner-occupancy requirement that defines a Junior ADU under state law.
What it costs in Burbank
Interior JADUs in Burbank typically range $75,000-$125,000, including the efficiency kitchen, separate entrance, and BWP service coordination.
How we do it
We design within the 500 sq ft maximum, produce the JADU-specific permit set, and build to the signed scope with no change orders per Haven Standard Clause 5.
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) | $75,000 - $125,000 |
| Above-garage ADU (all-in) | $110,000 - $180,000 |
Does a Junior ADU require a separate electrical meter in Burbank?
No, state law allows JADUs to share the primary residence’s electrical service, though BWP may require a sub-panel or load calculation to confirm capacity. Call (424) 325-4322 for an exact quote - estimates are free.
Can I convert any room in my Burbank home to an ADU?
Not every room qualifies - the space needs exterior access, sufficient ceiling height, and compliance with fire-separation requirements between units. We assess feasibility during our first site visit and document what we find with photos.
ADU Site Prep & Utilities in Burbank
ADU site prep and utilities in Burbank almost always means electrical panel upgrades and plumbing lateral work before construction can begin, because the 1940s-1960s housing stock was never designed for a second dwelling unit. BWP’s municipal utility status adds a specific wrinkle: contractors must open a BWP account and schedule BWP-specific electrical inspections independently of city building inspections, and teams accustomed to SCE or LADWP workflows consistently miss this step. ADU Site Prep & Utilities details our full prep and utility coordination service.
Electrical Panel Upgrade
Signs you need it
Your existing panel is rated below 200 amps, has no spare breaker spaces, or still uses fuses rather than breakers.
What it costs in Burbank
Electrical panel upgrades in Burbank typically run $4,500-$9,500, including the BWP permit, meter socket, and coordination with city electrical inspections.
How we do it
We open the BWP account, submit the load calculation, install the new panel and grounding system, and schedule the BWP inspection before final city inspection.
Plumbing Lateral
Signs you need it
Your home has original galvanized supply lines, visible corrosion at fixtures, or water pressure below 40 PSI when multiple taps run.
What it costs in Burbank
Plumbing lateral replacement in Burbank typically costs $6,500-$14,000 depending on trench length, pavement restoration, and whether the sewer lateral must also be replaced.
How we do it
We video-inspect the line, produce the trenching plan with utility clearance, replace with copper or PEX, and pressure-test before backfill.
What ADU Site Prep & Utilities Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Electrical panel upgrade | $4,500 - $9,500 |
| Plumbing lateral replacement | $6,500 - $14,000 |
| Foundation and grading (new detached) | $12,000 - $28,000 |
Does BWP require a separate account for my ADU?
For detached ADUs, yes - BWP requires a separate service account and meter set, which we coordinate as part of our single-contract scope. Call (424) 325-4322 for an exact quote - estimates are free.
How long does utility prep take before construction starts?
Utility prep typically adds 3-6 weeks before breaking ground, with BWP electrical inspections often the pacing item due to their independent scheduling system.

FAQs About ADU in Burbank
California state law overrides most HOA restrictions on ADUs, though Burbank HOAs may still enforce design guidelines for exterior appearance and materials. We review your CC&Rs during feasibility and flag any enforceable conditions before permit submission.
BWP is a municipal utility with its own account system, fee schedule, and inspection cadence; contractors must open a BWP account and schedule BWP electrical inspections separately from city building inspections, a step teams familiar with SCE or LADWP often miss.
Site visits are typically available within one week; permit submission follows once the feasibility study and design are complete, usually 2-4 weeks after contract signing depending on project complexity.

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."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."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.
