Burbank’s post-WWII housing stock - those 950-1,400 sq ft single-story homes on 6,000-7,500 sq ft lots in Rancho and Magnolia Park - was built for a different era. The detached garages we’re converting were never insulated or conditioned, and summer temperatures 10-15°F above coastal LA mean HVAC sizing isn’t guesswork here. Because Burbank is its own municipality with its own Building & Safety Department and Burbank Water and Power, the permit path and utility coordination differ completely from LA City neighbors like Toluca Lake. Junior ADU & Interior Conversion is how most Burbank homeowners start.
Why Burbank Homes Are Different
Burbank’s residential flatlands - Rancho, Magnolia Park, and the R-1 core - sit on lots carved out in the 1940s through early 1960s. The garages we’re converting sit on minimal slabs with no insulation and no conditioned connection to the main house. Before Burbank Building & Safety will sign off, we routinely remediate structure and build out the full thermal envelope from scratch.
The climate reality shapes every project. Burbank sits at the base of the Verdugo Mountains and records peak summer temperatures well above coastal zones. Right-sized HVAC is a non-negotiable line item, not an upgrade. Hillside parcels near the Verdugos fall within Very High Fire Hazard Severity Zones, triggering fire-hardening requirements - ember-resistant vents, ignition-resistant cladding, Class A roofing - that add cost to new detached construction.
Most critically, Burbank Water and Power operates independently from LADWP and SCE. Adding a sub-panel or standalone ADU meter means navigating BWP’s distinct interconnection process, fee schedule, and inspection sequence. Contractors who regularly pull permits in LA City or Glendale are routinely blindsided by the differences.
Our Main Burbank Services
Three services have their own dedicated Burbank pages. Here’s what each involves locally:
ADU Design & Permitting in Burbank
We produce the full permit set - architectural, structural, MEP - and manage plan check through Burbank Building & Safety’s specific sequencing. Because Burbank is an independent municipality, the submittal requirements, review timelines, and correction cycles differ from LA City. Our permit set is the core product, not an afterthought.

Garage Conversion ADU in Burbank
The detached one- and two-car garages common in Rancho and Magnolia Park are the primary conversion candidates.

New Detached ADU in Burbank
For homeowners with rear-yard space on R-1 lots, we design and build standalone units from foundation to finish. Hillside parcels near the Verdugos trigger fire-hardening requirements that we specify and coordinate within the same single contract.

Before
AfterJunior ADU & Interior Conversion in Burbank

Junior ADU & Interior Conversion in Burbank solves the problem of adding rental income or multigenerational space without touching the detached garage or building new in the yard. For the studio employees who dominate Burbank’s renter pool - Warner Bros., Disney, NBC - a finished basement or converted room near the Burbank Town Center corridor rents within days. The existing home’s footprint, not the lot size, drives feasibility here. Junior ADU & Interior Conversion covers the full scope under one contract.
Basement ADU
Signs you need it
You have a full or partial basement with ceiling height at or above 7 feet 6 inches, and you want independent rental income without altering the home’s exterior footprint.
What it costs in Burbank
Basement ADU conversions in Burbank typically run $95,000-$155,000 all-in, including egress windows, moisture remediation, and full MEP rough-in.
How we do it
We measure existing headroom, design the egress window layout to meet Burbank Building & Safety’s emergency exit requirements, remediate any moisture intrusion, rough in electrical, plumbing, and HVAC, then finish to the permitted drawings.
Room-to-ADU Conversion
Signs you need it
You have a bedroom or den with direct exterior access, a window, and sufficient square footage, and you want to create a separate rental unit under Burbank’s Junior ADU provisions.
What it costs in Burbank
Room-to-ADU conversions in Burbank typically run $75,000-$125,000 all-in, including kitchenette buildout, bathroom addition or upgrade, and separate metering where required.
How we do it
We verify the room meets Burbank’s Junior ADU size and access requirements, design the kitchenette and bathroom layout, coordinate BWP meter configurations, then build out to the permitted set with documented photos at each visit.
What Junior ADU & Interior Conversion Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Basement ADU conversion | $95,000 - $155,000 |
| Room-to-ADU conversion | $75,000 - $125,000 |
| Above-garage ADU (interior structure) | $85,000 - $140,000 |
Can a Junior ADU have its own meter in Burbank?
Yes, but Burbank Water and Power handles the interconnection, not LADWP. We coordinate the BWP application during design so the meter upgrade doesn’t delay final inspection. Call (747) 322-4648 for an exact quote - estimates are free.
Does my basement ceiling height work for an ADU?
Burbank Building & Safety requires 7 feet 6 inches minimum ceiling height; we measure during our first site visit and document the finding with photos. If the height is close, we evaluate excavation versus dropped systems. Call (747) 322-4648 for an exact quote - estimates are free.
ADU Site Prep & Utilities in Burbank

ADU Site Prep & Utilities in Burbank addresses what the existing property needs before or alongside the main build. The post-WWII slabs, original electrical panels, and aging plumbing laterals common in Rancho and Magnolia Park weren’t designed for additional dwelling units. Because BWP operates independently, electrical and gas coordination follows a different timeline than in LA City. ADU Site Prep & Utilities is quoted as a line item within the single written price.
Electrical Panel Upgrade
Signs you need it
Your existing panel is rated below 200 amps, or Burbank Water and Power requires a dedicated ADU meter that exceeds current capacity.
What it costs in Burbank
Electrical panel upgrades in Burbank typically run $4,500-$9,500, including BWP coordination, permit, and inspection.
How we do it
We verify existing amperage and BWP’s specific meter requirements, specify the new panel and sub-panel layout, pull the Burbank permit, and coordinate BWP inspection sequencing.
Plumbing Lateral
Signs you need it
Your home’s original sewer lateral is cast iron or clay from the 1950s-1960s, or Burbank Building & Safety requires upsized capacity for the additional unit.
What it costs in Burbank
Plumbing lateral replacement or upsizing in Burbank typically runs $8,500-$18,000, including trenching, materials, and city inspection.
How we do it
We camera the existing line, determine if trenchless or open-cut is appropriate for the Burbank soil conditions, coordinate with BWP if water main ties are affected, then replace and test to code.
What ADU Site Prep & Utilities Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Electrical panel upgrade | $4,500 - $9,500 |
| Plumbing lateral replacement | $8,500 - $18,000 |
| Foundation and grading (new detached) | $18,000 - $45,000 |
Does BWP require a separate meter for every ADU?
Not always - sub-metering may suffice for Junior ADUs, but BWP makes the final determination during plan check. We submit the electrical load calculations with the permit set to avoid surprises. Call (747) 322-4648 for an exact quote - estimates are free.
Can site prep be done after the ADU is designed?
We price site prep within the initial written quote so the scope is locked at signing per Haven Standard Clause 5; discovering a failing lateral mid-construction triggers change orders we don’t allow. Call (747) 322-4648 for an exact quote - estimates are free.
Brands We Service in Burbank
We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, and James Hardie within our single-contract model. Parts and materials are sourced through our Los Angeles office with typical turnaround of 5-10 business days for standard items. See our brands for the full list.
