Get your free estimateFast, Reliable Garage Conversion Contractor Across Woodland Hills
A typical garage conversion in Woodland Hills runs $85,000 to $165,000 before permit fees, with a garage-to-bedroom conversion starting around $85,000 and a full garage conversion ADU with kitchen and bath landing between $120,000 and $165,000. The work usually takes 5 to 8 months from first plan check to final inspection, and the biggest local variable is whether your property falls inside the Very High Fire Hazard Severity Zone, which most of Woodland Hills does. That single designation changes what materials you can use, what the city will approve, and what the job ultimately costs.

We schedule free estimates in Woodland Hills five days a week, and a live person answers every call at (361) 315-4177. You will not hit a voicemail queue when you want an answer about your garage.

Why Fielding ADU Builders Is Woodland Hills’s Preferred Garage Conversion Contractor Company

Fielding ADU Builders operates inside the Garrison Partners family, which has been building to The Garrison Standard since 2006. That standard is simple and it is the reason homeowners who have been burned once tend to call us second. Show up in the window, put the price in writing, build by the book, leave it clean, and stand behind it for a full year. Reed Calloway leads our garage conversion work, and he is the person you will talk to when you call about your project.
We are the Garage Conversion Contractor team that walks your lot before quoting, not a call center that emails a number. A garage conversion off Winnetka Avenue near Pierce College is not the same job as one on a hillside lot above Topanga Canyon Boulevard. Slope, access, sewer depth, panel location, and fire zone all move the price. We scope them in person and hand you a written price before any work starts. No change orders at the door, no “we didn’t see that when we quoted it” routine.
Our crews arrive in uniform and every person on your site has passed a background check. We pull permits through LADBS, we coordinate Title 24 energy compliance, and we schedule inspections. The Garrison Standard also means something specific on the back end: every garage conversion we build is covered by a written one-year guarantee. If workmanship fails inside that year, we return and correct it at no charge. That is not a verbal promise. It is on paper.
Garage to Bedroom Conversion in Woodland Hills
A Garage to Bedroom Conversion in Woodland Hills takes an existing attached or detached garage and turns it into a permitted living space with insulation, drywall, flooring, egress windows, and a proper heating and cooling system. Homeowners in neighborhoods like Walnut Acres and Carlton Terrace use this option when they need an extra bedroom for an aging parent, a returning adult child, or a caregiver, without adding square footage to the house. In Woodland Hills, you should budget $85,000 to $120,000 for a straightforward attached garage-to-bedroom conversion before permit fees.
Attached garage work
Attached garages are usually easier because the existing walls already share the house envelope and the electrical panel is nearby. The work still requires plans, a building permit, and an energy compliance check, but the trenching is minimal and the roofline does not usually change.
Detached garage work
Detached garages in Woodland Hills, especially the ones built in the 1950s through the 1970s, often have shallow footings and no existing sewer lateral. Trenching utilities from the main house to the detached structure is frequently the single biggest unplanned cost on this type of job.
Garage Conversion ADU in Woodland Hills

A Garage Conversion ADU in Woodland Hills is a full accessory dwelling unit built within the footprint of an existing garage, with its own kitchen, bathroom, and separate entrance. Homeowners choose this route when they want rental income, a long-term guest suite, or a place for an adult child to live independently. In Woodland Hills, a garage conversion ADU runs $120,000 to $165,000 before permit fees, depending on whether the existing foundation can support the build or needs underpinning, and whether the main panel must be upgraded from 100 amps to 200 amps.
Fire zone construction
Because most of Woodland Hills sits in a Very High Fire Hazard Severity Zone, the LADBS plan check will require ignition-resistant assemblies. That means Class A roofing materials, ember-resistant vents, and boxed-in eaves. A conversion in Burbank or Encino would not face the same list. You plan for it here from day one.
Height and setback rules
The city caps a single-story ADU at 16 feet in height. For most garage conversions that is not a problem because the existing structure is already under the cap. But if you are thinking about raising the roofline to add loft storage or living space, the 16-foot ceiling becomes the controlling measurement on your plans.
Trusted Brands We Service in Woodland Hills
We build conventional garage conversions with James Hardie fiber-cement siding and conventional framing, and we also work with prefabricated platforms from Abodu and Cover when the lot and the schedule make a factory-built ADU the better call. Dvele is another option for homeowners who want a high-performance envelope. For a garage conversion in Woodland Hills, the brand matters less than the engineering behind it, but we stock the materials common to these systems and can get parts quickly for our Woodland Hills jobs because we coordinate through our Los Angeles office. You will not wait on a backordered panel from out of state.
Common Garage Conversion Contractor Problems We See in Woodland Hills Homes
- Very High Fire Hazard Severity Zone review gets skipped. Converting a garage here without ignition-resistant assemblies means the LADBS plan check gets kicked back and the schedule slips weeks. We scope the fire-zone requirements before we quote, so the plan check goes through the first time.
- Slab and utility relocation gets underestimated. Woodland Hills garages are typically older detached structures with shallow footings and no sewer lateral. Trenching to the main house is often the biggest unplanned cost on a conversion, and it should be in the written price before you sign.
- The 100-amp panel reality. Many Woodland Hills homes still run 100-amp panels that cannot carry an ADU’s kitchen and HVAC load under Title 24. A panel upgrade adds real money, and any contractor who quotes a garage conversion without checking the panel is guessing.
- Detached garage foundations were never engineered for living space. A 1970s post-and-beam slab in a Woodland Hills backyard was built to hold a car, not a bedroom and a bathroom. Underpinning and thickened-edge footings are common on these jobs, and they should be scoped during the estimate, not discovered after demo.

What moves the number is the fire-zone construction, the condition of the existing slab, the distance from the garage to the main sewer line, and whether the panel needs to be replaced.

FAQs About Garage Conversion Contractor in Woodland Hills
Yes. Because most of Woodland Hills lies inside the Very High Fire Hazard Severity Zone, the LADBS plan check requires ignition-resistant assemblies on a garage conversion: Class A roofing, ember-resistant vents, and boxed-in eaves are the standard items. A conversion in Burbank or Encino would not face the same requirements. If you are planning a garage conversion in Woodland Hills, build the fire-zone work into your budget from the start. Call (361) 315-4177 for an exact quote, estimates are free.
Plan on 5 to 8 months. The LADBS plan check runs 4 to 8 weeks depending on workload, fire-zone review adds time, and construction on a detached garage with underpinning and trenching takes 4 to 6 months. Our crew converted a detached two-car garage off Hatteras Street near Warner Center into a 480-square-foot garage-to-bedroom ADU with a full bath and kitchenette, and the schedule ran six months from start to final inspection. Call (361) 315-4177 to get a written timeline for your specific lot.
Usually not. A garage conversion ADU with a kitchen, bathroom, and HVAC system needs more capacity than a 100-amp panel can deliver under Title 24 load calculations. Most Woodland Hills homes built in the 1960s and 1970s still have 100-amp panels, so a 200-amp upgrade is part of the job. Budget $4,000 to $7,000 for the panel swap. Call (361) 315-4177 and we will check your panel during the free estimate.
The biggest reason is the existing slab. Woodland Hills garages from the 1950s through the 1970s were built on shallow footings designed for a car, not a living space. When the slab is not thick enough to support new walls, or when the footing depth is insufficient for a permitted dwelling, the job needs underpinning and a thickened edge before framing can start. A contractor who does not scope that before quoting is not doing you a favor. We put it in the written price up front. Call (361) 315-4177 for a free estimate that includes a foundation review.
Yes. A garage conversion that creates an independent dwelling unit requires a building permit for the conversion and an ADU plan check through LADBS, even if you are not adding square footage. The ADU designation is what triggers the fire-zone review, the Title 24 energy compliance, and the panel load calculation. We pull the permits, coordinate the inspections, and keep the schedule moving. Call (361) 315-4177 to talk through your garage conversion in Woodland Hills.
