Burbank’s 1940s-to-1960s housing stock makes Junior ADU & Interior Conversion one of our most called-about services here. These postwar stucco bungalows sit on 6,000-7,500 sq ft lots with existing footprints that often convert more cleanly than owners expect, though the original wiring, asbestos in roofing and drywall, and BWP’s separate electrical queue add steps that contractors from neighboring cities routinely miss.
Why Burbank Homes Are Different
Burbank sits deep in the inland San Fernando Valley, where summer highs of 100-108°F run 10 to 15 degrees above coastal LA. That gap changes everything about HVAC sizing for ADU mini-splits; we specify higher cooling loads here than for identical square footage in Santa Monica or Culver City.
The housing stock is remarkably consistent: postwar stucco bungalows, 900-1,400 sq ft, built 1940-1965, with detached single-car garages that are the most common conversion target. These garages almost always need panel upgrades, asbestos assessment, and rewiring before they’re habitable. Properties on the Verdugo Mountain foothill edges fall within high fire hazard severity zones, triggering additional defensible-space and ember-resistant construction requirements. South of Hollywood Burbank Airport, around Empire Avenue, noise insulation standards require upgraded windows and wall assemblies that add cost a mile north would not.
And Burbank Water and Power is its own municipal utility, not LADWP or SoCal Edison. Every electrical service upgrade, new meter, and interconnection runs through BWP’s separate scheduling, fee schedule, and inspection queue. Contractors who build across city lines in Glendale or North Hollywood consistently underestimate this distinction.
Our Main Burbank Services
These are the three services Burbank homeowners call about most, each with its own detailed Burbank page.
ADU Design & Permitting in Burbank
We produce the full permit set, structural calculations, and Title 24 energy compliance as a standalone deliverable or as the first phase of a design-build contract. In Burbank, this means navigating BWP’s separate electrical review, fire hazard severity zone requirements for foothill properties, and airport noise zone insulation standards south of Empire Avenue. ADU Design & Permitting in Burbank covers the full scope.
Garage Conversion ADU in Burbank
The detached single-car garages common in Burbank’s postwar neighborhoods are our most frequent conversion target. Almost all need asbestos assessment of original roofing and drywall, 100-amp-to-200-amp panel upgrades through BWP, and re-routing of early postwar wiring before permitting. We handle each step under one contract at one written price. Garage Conversion ADU in Burbank has the full breakdown.
New Detached ADU in Burbank
For homeowners with usable rear yard space on these 6,000-7,500 sq ft lots, a new detached unit offers the most rental income potential. Foothill properties require defensible-space planning and ember-resistant exterior finishes. We coordinate prefab systems from Abodu or Cover within the same single contract. New Detached ADU in Burbank covers siting, sizing, and pricing.

Junior ADU & Interior Conversion in Burbank
Junior ADU & Interior Conversion in Burbank converts existing square footage within the main house, attached garage, or basement into a self-contained unit with its own kitchenette and exterior entrance. Burbank’s postwar bungalows offer surprising opportunities here: the original floor plans often include underutilized back bedrooms, enclosed porches, or partial basements that convert cleanly once asbestos and wiring are addressed. The 100-108°F summer highs make proper mini-split sizing critical, and BWP’s separate electrical queue means panel upgrades for these units need early scheduling. We handle Junior ADU & Interior Conversion as a single contract from measured drawings through final inspection.
Room-to-ADU Conversion
Signs you need it
You have a back bedroom, den, or enclosed porch with exterior wall access that sits unused while you’re paying full mortgage on a house you bought between 2015 and 2025.
What it costs in Burbank
Room-to-ADU conversions in Burbank typically run $85,000-$135,000 all-in, including asbestos assessment, electrical panel upgrade through BWP, and Title 24 compliance.
How we do it
We measure existing conditions, produce the permit set with BWP electrical specifications, remove and remediate asbestos-containing materials if present, rewire to 200-amp service, install the kitchenette and mini-split, and pass final inspection with a documented photo record at each visit.
Interior JADU
Signs you need it
You need a separate living unit for family or rental income but your lot coverage or setback doesn’t allow a detached ADU, or you want to preserve yard space.
What it costs in Burbank
Interior JADUs in Burbank typically run $75,000-$125,000 all-in, with lower utility tie-in costs than detached units but the same BWP electrical upgrade requirements.
How we do it
We identify the smallest viable footprint within your existing layout, design the kitchenette and exterior entrance to code, produce the JADU-specific permit set, coordinate BWP electrical review, and build to the permitted drawings under our 365-Day Done Right Promise.
What Junior ADU & Interior Conversion Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Room-to-ADU conversion, all-in | $85,000-$135,000 |
| Interior JADU, all-in | $75,000-$125,000 |
| Above-garage ADU, all-in | $110,000-$165,000 |
Does a Junior ADU need its own electrical meter in Burbank?
No, a JADU can share the main home’s meter under state law, though many Burbank owners opt for a separate BWP meter to simplify rental billing. Call (626) 427-9813 and we’ll walk through which setup fits your project.
Can I convert a basement to an ADU in Burbank?
Partial basements in Burbank’s postwar stock can convert if ceiling height meets 7’6″ minimum and egress windows comply with current code. We assess this in our first site visit and document findings with photos.
ADU Site Prep & Utilities in Burbank
ADU Site Prep & Utilities in Burbank addresses the pre-construction work that determines whether your project stays on schedule or stalls at the first inspection. Burbank’s postwar housing stock means nearly every garage conversion and many interior conversions need electrical panel upgrades through BWP’s separate queue, not LADWP’s. The 100-108°F inland heat also drives higher HVAC electrical loads, making 200-amp service the practical minimum for most ADUs here. We coordinate ADU Site Prep & Utilities as an integrated scope within your design-build contract, not a surprise add-on.
Electrical Panel Upgrade
Signs you need it
Your existing panel is 100 amps, your main breaker trips when the AC runs, or BWP requires service upgrade for the new ADU meter.
What it costs in Burbank
Electrical panel upgrades through BWP in Burbank typically run $8,000-$15,000 including the new 200-amp panel, BWP coordination, and inspection.
How we do it
We submit BWP’s service request, schedule the disconnect and reconnect, install the new panel and grounding system, and coordinate BWP’s inspection before rough electrical begins.
Foundation & Grading
Signs you need it
Your garage slab is cracked, sloped, or less than 4 inches thick, or you’re building a new detached ADU on a sloped lot in the Verdugo foothills.
What it costs in Burbank
Foundation and grading work in Burbank typically runs $12,000-$28,000 for garage slab replacement or new stem-wall foundations on moderate slopes.
How we do it
We test existing slab thickness and soil bearing, design the replacement or new foundation to Burbank’s seismic and hillside codes, and pour with documented slump and rebar placement photos.
What ADU Site Prep & Utilities Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Electrical panel upgrade (BWP) | $8,000-$15,000 |
| Foundation & grading | $12,000-$28,000 |
| Plumbing lateral extension | $4,500-$9,000 |
How long does BWP take to approve an electrical upgrade?
BWP’s service upgrade queue typically runs 3-6 weeks from application to scheduling, longer than LADWP in neighboring areas. We submit immediately upon contract signing to keep your project on track.
Is asbestos always found in Burbank garage conversions?
Not always, but pre-1980 roofing and drywall in Burbank’s postwar stock tests positive often enough that we budget for assessment and remediation in every quote. You’ll know the exact cost before work starts, per Haven Standard Clause 1.

FAQs About ADU in Burbank
Burbank’s Planning & Building Division typically processes complete ADU applications in 90-120 days, with Junior ADUs often moving faster. BWP electrical review runs on a separate timeline; we coordinate both from day one to prevent gaps.
State law limits HOA prohibition of ADUs, but Burbank’s older CC&Rs sometimes contain parking or architectural review requirements that add steps. We review your documents during our first meeting and flag any issues in the written scope.
Yes, but properties south of Hollywood Burbank Airport around Empire Avenue must meet noise insulation standards with upgraded windows and exterior wall assemblies. We design to these requirements from the first permit set, not as a mid-project surprise.

What Burbank Customers Say
"The permit set and the build were one contract with one number. Our neighbours used two firms and spent a year watching them blame each other."
- Helena V."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."Every allowance was itemised at the start, so the finish selections did not turn into a surprise at the end."
- Benedict H.
