A garage conversion in Sherman Oaks typically runs $95,000 to $210,000 before permit fees, and the full build usually takes four to seven months from plan check to final inspection. That range reflects what we see across Van Nuys Boulevard, Longridge Avenue, and the hillside streets north of Ventura, where structural retrofits on pre-1950 garages are more rule than exception. We’re Fielding ADU Builders, the Garage Conversion Contractor team inside the Garrison Partners family. If you want a written number before any work begins, call (361) 315-4177.
Why Fielding ADU Builders Is Sherman Oaks’s Preferred Garage Conversion Contractor Company
Sherman Oaks homeowners don’t hand a garage build to just anyone. Too many have already paid a deposit, watched the crew disappear, and then found out the permit was never pulled. We answer to a different standard. The Garrison Standard, set by our parent organization in 2006, puts the price in writing before the first inspection, names exactly what the one-year written guarantee covers, and sends background-checked, uniformed crews to every job.
Reed Calloway leads our team, and he is the person you’ll speak with when you call about your project. We coordinate dispatch from our Los Angeles office, and our crews work throughout Sherman Oaks on a regular schedule. When a homeowner off Kester Avenue asks us whether their foundation can hold a second-story addition, we don’t guess. We bring our structural engineer, we look at the slab, and we tell you what the retrofit will cost before you commit.
We have built Garage Conversion Contractor in Sherman Oaks projects from Coldwater Canyon to Sepulveda Basin. The homes along the flats and the hillside lots above Ventura Boulevard each come with their own set of code requirements. We know which ones applywhere.
Garage Apartment Conversion in Sherman Oaks
A Garage Apartment Conversion in Sherman Oaks turns a standalone or attached garage into a rentable or family-occupied dwelling with its own kitchen, bath, and private entrance. On a typical Sherman Oaks lot, that job runs $130,000 to $210,000. Older detached garages with unreinforced masonry walls or settled slabs push the number higher.
Detached Garage to Rentable ADU
The detached garage behind a 1940s Sherman Oaks home usually sits at the back of the lot, accessed by a narrow driveway off a street like Dickens or Stansbury. Converting it means upgrading the foundation, adding shear walls, insulating to current Title 24 standards, and running new electrical service from the main panel. The result, in most cases, is a one-bedroom unit that rents for $2,400 to $2,900 a month in this market.
Attached Garage with Interior Access
When the garage shares a wall with the house, we can often convert it into a true ensuite addition: bedroom, bathroom, walk-in closet, direct door into the hall. These typically come in at the lower end of the Sherman Oaks range, around $95,000 to $150,000, because the roof and one wall already exist. The catch is fire separation: the shared wall must be drywalled to a one-hour rating, and the existing door from the house into the garage must be replaced or removed depending on the floor plan.
Garage Conversion Permit in Sherman Oaks
A Garage Conversion Permit in Sherman Oaks is issued by the Los Angeles Department of Building and Safety, not by a separate city hall, and it follows the LADBS plan-check path for an ADU or room addition. For a standard conversion on a flat lot south of Ventura Boulevard, plan check can clear in two to four months. Hillside overlays, front-yard setback issues, or a required structural retrofit can stretch that to six months or longer. Permit and plan check fees for garage conversions in this area typically land between $6,000 and $12,000.
Plan Check and Structural Review
LADBS reviews every set of plans twice: once for zoning and once for structure. If the garage sits inside the Sherman Oaks Community Plan boundary or falls under a Hillside ordinance, the plan checker will ask for a survey pinning the structure’s exact location relative to the property line. If the garage was built before 1950 and shows the soft-story signs common along Moorpark Street and Ventura Boulevard, expect a mandatory shear wall or foundation retrofit before the permit clears.
The Final Inspection
We schedule inspections at each milestone: foundation, rough framing, electrical rough, plumbing rough, insulation, drywall, then final. The final inspection is where the deputy verifies the conversion matches the approved plans exactly, including egress window sizes, smoke and CO detectors, and the new address posting if you’re converting to an ADU. A missed framing nail pattern on a shear wall, the kind of thing we corrected on a recent Longridge Avenue build, will fail you on the first pass.
Trusted Brands We Service in Sherman Oaks
We build conventionally and with prefab systems. For Sherman Oaks lots that allow factory-built ADUs, we work with Abodu, Dvele, and Mighty Buildings. Those units arrive 80 to 90 percent complete and shorten on-site time by six to ten weeks. For conventional builds, including most garage apartments and attached conversions, we frame with standard lumber and finish with James Hardie siding. We keep local stock for Sherman Oaks projects and order from the brand’s California distribution centers, so a replacement panel or door never waits on a cross-country shipment.
Common Garage Conversion Contractor Problems We See in Sherman Oaks Homes
- Unreinforced masonry in pre-1950 detached garages. Sherman Oaks has a high concentration of 1930s through 1950s garages with hollow clay tile or under-reinforced block walls. These hold up fine as storage, but the moment you cut window openings for an ADU, the wall loses what little shear strength it had. We brace, add hold-downs, and sometimes rebuild the wall entirely before framing begins.
- Soft-story conditions along the Ventura Boulevard corridor. Garages with a living space above or a shallow roof line on the Boulevard side often have what engineers call a soft story: the garage wall has more openings than structural wall. Converting these without a shear wall analysis gets you a red tag during rough framing.
- Parking replacement requirements nobody mentions upfront. If your garage was required parking under the original tract map, LADBS will ask what replaces it. On lots where the driveway can accommodate two cars in tandem, that usually satisfies the requirement. On narrow lots north of Ventura, you may need a front-yard parking pad or a variance. We verify this during the feasibility stage, before you pay for plans.
- Slabs that have settled toward the street. Sherman Oaks sits on alluvial fan soil, and back-of-lot garages on the older streets often pitch a half-inch or more toward the curb. Before we frame over it, we check with a structural engineer. A rebuild of the slab adds $12,000 to $28,000, and that’s a number you deserve to know on day one.

FAQs About Garage Conversion Contractor in Sherman Oaks
Only if LADBS determines the garage was required parking when the tract was originally recorded. On most Sherman Oaks lots, tandem driveway parking satisfies the replacement requirement. On narrow lots north of Ventura Boulevard or inside specific Sherman Oaks Community Plan overlays, you may need a front-yard pad or a variance. We check this during feasibility, before you pay for plans, so you know the answer for your specific address. Call (361) 315-4177 to ask about your lot.
Foundation, rough framing, shear wall, electrical rough, plumbing rough, insulation, drywall, and final. If you’re converting to an ADU, the final inspection also verifies egress windows, smoke and CO detection, and the official address posting. We schedule each one and stand with the inspector on site. Call (361) 315-4177 and we’ll walk you through the full sequence for your project.
Two to four months for a standard conversion on a flat lot south of Ventura. Six months or longer if the project touches a hillside overlay, a front-yard setback, or a structural retrofit on a pre-1950 garage. Our schedule assumes the longer path until the plan checker tells us otherwise. Call (361) 315-4177 to see where your address falls.
Yes, and it’s common in Sherman Oaks. You can wall off a storage room with its own roll-up door and convert the remaining square footage into a studio or one-bedroom unit. The storage area must have a fire-rated separation from the living space, and the roll-up door must remain functional or be replaced with a rated wall. We draw that split on every plan where the homeowner wants it. Call (361) 315-4177 for a feasibility look at your garage.
What we find under the slab or inside the walls. A settled foundation, dry-rotted sill plates, or a shear wall requirement that wasn’t on the original plan set. That’s why we do a full structural review before we quote, not after. The Garrison Standard also means the price goes in writing before any work starts, and if we miss something in our own review, we eat the correction. Call (361) 315-4177 and we’ll tell you what we’d look for on your street.
