Trusted Garage Conversion ADU for Burbank Homeowners
A garage conversion ADU in Burbank typically runs $85,000-$165,000 all-in, from the initial measured drawings through final inspection. Most attached garage conversions in Burbank move from permit submission to certificate of occupancy in 6-10 months, depending on whether the existing slab and electrical panel need upgrading. Call (747) 322-4648 to schedule your free estimate, and we’ll bring a written price to the first meeting.
We’ve designed, permitted, and built more than 900 ADUs since 2015, the year California’s ADU laws began their major shift. Burbank’s specific combination of hillside zones, airport influence areas around Hollywood Burbank Airport, and its own municipal code amendments means a garage conversion here isn’t a standard Los Angeles process. The city requires fire sprinkler compatibility checks in certain zones, and the Burbank Water and Power utility has separate meter requirements that differ from LADWP territory just across the border in North Hollywood or Glendale. We’ve navigated these exact conditions hundreds of times, and every project starts with a written price before any work begins, per Haven Standard Clause 1.
What Our Garage Conversion ADU Service Includes
Attached Garage Conversion
An attached garage conversion turns the structure already connected to your main house into a self-contained dwelling unit with its own kitchen, bathroom, sleeping area, and separate entrance. In Burbank, these conversions often trigger the city’s Residential Impact Review when the added square footage pushes total lot coverage near 45%, and we’ve learned which Planning staff reviewers flag kitchen proximity to property lines versus those who focus on parking replacement calculations. We handle the full permit set, the structural analysis of whether your existing shared wall meets fire-rated assembly requirements, and the construction under one contract at one written price.

Detached Garage Conversion
A detached garage conversion transforms a standalone structure into a complete ADU, and Burbank’s code treats these more generously on setbacks than attached conversions in some R-1 zones. The existing slab is often 4 inches thick, adequate for storage but requiring evaluation for habitable space loads; we specify exactly what the foundation line item covers after our structural engineer’s site visit. Utility trenching from the main house to the detached structure, separate meter coordination with Burbank Water and Power, and compliance with the city’s landscape requirements for converted structures all sit within our single contract.

Carport Conversion
Carport conversions in Burbank face a specific hurdle: many carports lack perimeter walls sufficient for insulation, weatherproofing, and security standards for habitable space. We assess whether the existing posts and open framing can support enclosed walls and a proper roof assembly, or whether the structure needs partial rebuild. The city’s parking replacement rules also apply differently to carports than enclosed garages, and we’ve secured approvals where clients replace the lost covered parking with tandem spaces or off-site arrangements approved under Burbank’s specific flexibility provisions.

Garage Partition & Bathroom Add
Some Burbank homeowners want to keep garage storage or workshop space while carving out a studio or bedroom with bathroom access. This partial conversion requires careful fire separation between the habitable and non-habitable zones, typically a one-hour rated assembly with self-closing doors. We design the partition layout to maximize the usable ADU square footage while preserving the garage door and vehicle access if desired, and we document exactly which code path applies: full ADU with shared wall, or Junior ADU with owner-occupancy requirements.

Garage JADU
A Junior ADU, or JADU, is limited to 500 square feet and must be contained within the existing walls of your home or attached garage, with a separate entrance and either efficiency kitchen or full kitchen depending on Burbank’s current interpretation. The owner-occupancy requirement means you must live in either the main house or the JADU, and we verify this condition in writing before permit submission. JADUs avoid some utility connection fees but require shared bathroom or separate bathroom addition within the existing footprint, and our permit set documents both configurations for Planning review.

Brands We Service for Garage Conversion ADU

While most garage conversions are stick-built on site, we specify and coordinate prefab and modular systems when they serve the project. For James Hardie fiber-cement siding, we integrate their ColorPlus finishes into the exterior envelope specification for Burbank’s sun exposure and occasional Santa Ana wind conditions, and our crews are trained on the specific fastening patterns that maintain the 30-year warranty. Abodu units are typically freestanding structures, but we’ve adapted their panelized wall systems for detached garage rebuilds where the existing structure is unsalvageable, maintaining the single-contract model while leveraging Abodu’s engineered lumber and rapid-close weather barrier.
Cover and Dvele systems enter our garage conversion work when clients want smart-home infrastructure or net-zero energy targets; we coordinate their electrical and HVAC specifications with the Burbank building inspector’s checklist before rough-in, not after. Whether your project involves these brands, conventional framing, or a hybrid approach, we specify, source, and install within the same written contract. No separate procurement phase, no finger-pointing if a component doesn’t fit.
Before
AfterSigns You Need Garage Conversion ADU Right Now
- Your garage sits empty while housing costs climb. Burbank’s median rent for a one-bedroom apartment now exceeds $2,400 monthly, and an unused 400-square-foot garage represents untapped income or family flexibility. The 2019-2024 ADU law changes removed owner-occupancy requirements for standard ADUs, meaning you can rent both units immediately upon certificate of occupancy.
- Your household needs multigenerational space without moving. Adult children returning home, aging parents needing proximity, or a home office that actually closes a door, these are permanent structural needs, not temporary fixes. A garage conversion keeps everyone on the same property with genuine independence.
- The garage structure is deteriorating and needs investment anyway. A failing roof, slab cracking, or dry rot in the door frame means you’re already facing a five-figure repair bill. Converting while repairing spreads mobilization costs across both budgets and qualifies for ADU-specific financing products that garage repairs alone do not.
- You have a written estimate from another firm that feels vague. Phrases like “allowance for unknowns” or “TBD at time of construction” typically signal 15-30% cost growth. Our Free Second Opinion reviews any written estimate you’ve received, line by line, against Burbank’s actual permit fees and our completed project database.
- Your property tax assessment is stable and Proposition 13 protects your base. ADUs in California do not trigger full property reassessment, only the value of the new construction added to your existing base year. Delaying means higher construction costs and potentially higher reassessment rules if legislation shifts.
Our Garage Conversion ADU Process - Step by Step

- 1
Site Measure and Feasibility Review. We visit your Burbank property, photograph the existing garage from slab to rafters, and record precise dimensions with laser measurement. Within one week, you receive a written feasibility report stating what the structure can support, what Burbank’s code requires, and whether your project faces any airport height restrictions or hillside grading triggers. This report is free and carries no obligation.
- 2
Design and Permit Set Development. Our architects produce construction drawings that satisfy Burbank Building Division’s plan check requirements, including Title 24 energy calculations, structural calculations signed by a California-licensed engineer, and landscape compliance plans. You receive draft drawings for review before submission, and we revise twice within the base fee. The permit set is the core product, not an afterthought.
- 3
Written Price and Contract. Once the design is fixed, we produce a line-item written price covering every phase: demolition, foundation, framing, MEP rough-in, insulation, finishes, fixtures, and final connections. Haven Standard Clause 1 locks this price at signing; no door-side upsells, no scope creep. You sign one contract for design, permitting, and construction.
- 4
Permit Submission and Correction Response. We submit to Burbank’s Planning and Building divisions, attend correction meetings, and revise plans as required. Our 2015 start date means we’ve worked through Burbank’s transition to electronic plan check and know which reviewers prioritize fire access versus parking replacement. We don’t hand off permit chasing to a third party.
- 5
Construction and Final Documentation. Our background-checked, uniformed crews execute the build with a documented photo record on every visit, you receive evidence of what was found and what was done, not a summary of how it felt. After final inspection and certificate of occupancy, the 365-Day Done Right Promise remains in force: if the finished ADU is not built to the permitted drawings, we make it right, in writing, before the project starts.
How Much Does Garage Conversion ADU Cost in Burbank?
A typical attached garage conversion in Burbank runs $85,000-$125,000 all-in, from measured drawings through final inspection, per our garage conversion ADU cost guide. Detached garage conversions usually fall between $110,000-$165,000 due to utility trenching, separate meter costs, and the additional envelope work. Carport conversions start around $95,000 because they require complete wall and roof assembly from scratch. Garage partition projects with bathroom adds range $45,000-$75,000 depending on whether the bathroom needs slab cutting for drainage. JADUs, capped at 500 square feet, typically run $65,000-$95,000 with shared utility connections reducing infrastructure costs.
Several factors push these ranges up or down. Existing slab thickness and condition determine whether foundation work adds $8,000-$20,000. Electrical panel capacity, many Burbank homes built 1940-1970 have 100-amp service insufficient for a second dwelling unit, drives a $3,500-$7,500 panel upgrade. Hillside zones requiring grading or retaining wall work add engineering and inspection layers. And Burbank Water and Power’s separate meter fees, currently distinct from LADWP’s structure, run approximately $4,000-$8,000 for new service depending on trench length.
To avoid overpaying, demand a written line-item quote before any work begins, not a square-foot estimate with “refinement later.” Compare whether permit fees, utility connection fees, and final inspection sign-offs are included or excluded. Ask for comparable completed projects in Burbank specifically, not Los Angeles County generally, Burbank’s airport influence area and utility structure create conditions that Glendale or North Hollywood experience differently.
Our free estimate includes all of this: site measure, feasibility assessment, preliminary design discussion, and a written price range you can compare against any other quote. Call (747) 322-4648 to schedule.

Frequently Asked Questions - Garage Conversion ADU in Burbank

A garage conversion ADU transforms an existing garage into a legally permitted accessory dwelling unit with independent living facilities, kitchen, bathroom, sleeping area, and separate entrance. In Burbank, this requires compliance with the California Building Code, Burbank’s municipal code amendments, and specific conditions for parking replacement and fire safety. We handle the full conversion from measured drawings through certificate of occupancy under one contract at one written price.
Most Burbank garage conversion ADUs take 6-10 months from contract signing to certificate of occupancy, with 2-4 months for permit set development and city review, and 4-6 months for construction. Burbank’s electronic plan check has reduced initial review times compared to paper submission, but correction cycles vary based on project complexity and whether hillside or airport zone conditions apply. Call (747) 322-4648 for a timeline estimate specific to your property and scope.
Attached garage conversions in Burbank typically cost $85,000-$125,000 all-in, detached conversions $110,000-$165,000, and JADUs $65,000-$95,000, with final price depending on slab condition, electrical panel capacity, utility connection requirements, and finish selections. Every project receives a written line-item price before any work begins, per Haven Standard Clause 1, with no allowance for unspecified “unknowns.” Call (747) 322-4648 for your written estimate.
Yes, we specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie within our single-contract model. For garage conversions specifically, we most often integrate James Hardie siding systems and have adapted Abodu panelized construction for detached garage rebuilds where the existing structure cannot be salvaged. The brand selection serves the project requirements, not the other way around.
No, a garage conversion ADU is planned construction, not an emergency service, and we do not promise same-day or next-day mobilization. The proper sequence, feasibility, design, permit, then build, protects your investment and prevents costly corrections. If you have an urgent housing need, we can accelerate the design phase and pre-order long-lead items like windows, but permit submission follows when the set is complete and accurate, not before.
Every garage conversion ADU is backed by our 365-Day Done Right Promise: if the finished unit is not built to the permitted drawings, we make it right. This is documented in writing before construction begins, not offered verbally after completion. Standard manufacturer warranties apply to fixtures, appliances, and specified materials like James Hardie siding. Our workmanship warranty covers installation quality for one year, with extended structural warranties where California law requires.
Clear the garage interior for access to all walls, the slab, and the electrical panel; locate your property survey or plot plan if available; and gather any previous permits or inspection records for the structure. If you have a written estimate from another firm, bring it for our Free Second Opinion review. We’ll photograph existing conditions, measure precisely, and return a written feasibility assessment with price range within one week of the site visit. Call (747) 322-4648 to schedule.
