Get your free estimateFast, Reliable Garage Conversion Contractor Across Van Nuys
A garage conversion in Van Nuys typically costs between $85,000 and $145,000 before permit fees, depending on whether you’re adding a bathroom, upgrading the foundation, or installing a new electrical subpanel. Most homeowners off Van Nuys Boulevard and Hazeltine Avenue are converting an underused two-car garage into a bedroom suite, home office, or rental unit, and the biggest cost driver is almost always what’s hiding under the slab. Fielding ADU Builders handles the full scope: structural engineering, LADBS permits, the fire-flow test if your street requires one, and the final inspection. We work from the Los Angeles office with crews dispatched locally to Van Nuys, so you’re never waiting on a crew from across the county. Call (361) 315-4177 to have Reed Calloway walk your specific lot and give you a written price before any work begins.
Why Fielding ADU Builders Is Van Nuys’s Preferred Garage Conversion Contractor Company
Homeowners in Van Nuys keep coming back to us for one reason: we put the price in writing before the first hammer swings. That’s the Garrison Standard, and it’s been the operating rule since 2006. No allowances that drift. No change orders at the door. The number you approve is the number on the final invoice.
Reed Calloway leads every Van Nuys project personally. He’s walked dozens of lots in the neighborhoods east of Kester Avenue and north of Oxnard Street, and he knows which ones will trigger a fire-flow test and which won’t. That’s the kind of local knowledge that saves you a $4,000 surprise mid-project.
Our crew members are background-checked and uniformed. You’ll know exactly who’s on your property, and someone answers the phone 24/7 if you have a question at midnight. For Van Nuys homeowners who’ve already been burned by a contractor who ghosted, that matters.
Garage Conversion to Living Space in Van Nuys
Garage Conversion Contractor work in Van Nuys means turning dead square footage into conditioned living space, and the scope depends on whether the garage is attached or detached. A typical attached conversion off Victory Boulevard or Sherman Way runs $90,000 to $130,000, while a detached conversion with a new foundation can push toward $145,000. The job includes sealing the existing slab, framing interior walls, upgrading insulation to Title 24 standards, running electrical, and installing drywall, flooring, and HVAC.
Leveling the Existing Slab
Pre-1960 garages in Van Nuys often sit on slabs that have heaved or cracked from decades of Valley heat and clay soil movement. We check with a laser level, then either self-level or pour a new overlay. If the stem wall is unreinforced, that’s a structural fix before anything else happens.
Electrical and HVAC Scope
Your converted space needs its own circuit, and most Van Nuys homes built in the 1950s have 100-amp panels that are already at capacity. A subpanel upgrade is common and adds $3,000 to $6,000. We typically spec a ductless mini-split for cooling because it’s the cleanest install in a converted garage footprint.
Garage to Bedroom Conversion in Van Nuys
A Garage to Bedroom Conversion in Van Nuys is the most common request we field, and it costs $95,000 to $140,000 depending on whether you’re adding an en-suite bath. The bedroom must have an egress window, a permanent heat source, and a closet to meet LADBS habitability requirements. On a 1950s ranch off Hazeltine Avenue near Van Nuys Boulevard, our crew recently swapped an old Tuff Shed storage unit for a James Hardie-clad addition with a new egress window and mini-split. The homeowner chose a Cover panelized wall system to meet 2022 Title 24 requirements, and we passed final inspection with LADBS on the first try after adjusting the ceiling height for the existing low-pitch roof.
Egress and Light Requirements
LADBS requires a bedroom to have an operable window with at least 5.7 square feet of clear opening for emergency escape. In a converted garage, that usually means cutting a new opening in an exterior wall and installing a code-compliant window. We handle the framing, flashing, and stucco patch so the exterior still looks clean from the street.
Bathroom Additions in a Converted Garage
Adding a full bath pushes the project into plumbing territory: new drain lines under the slab, a vent stack through the roof, and a separate 20-amp circuit for a GFCI outlet. That’s $25,000 to $45,000 on top of the base conversion cost, and it’s the single biggest reason budgets move between bid and contract.
Trusted Brands We Service in Van Nuys
We work with what actually fits your lot and budget. That means conventional stick framing with James Hardie siding when the roofline is simple, and panelized systems like Cover, Abodu, or Dvele when speed and Title 24 compliance matter more. For Van Nuys homeowners researching prefab options online, we can walk through the real tradeoffs: panelized systems cut framing time by three to four weeks, but they require a crane and a flat staging area, which can be tight on a 5,000-square-foot lot off Sepulveda. We stock the common lumber, rough electrical, and finish materials for Van Nuys jobs at our Los Angeles yard, so we’re not waiting on a supplier in Riverside when the schedule tightens.
Common Garage Conversion Contractor Problems We See in Van Nuys Homes
- Unreinforced slabs under pre-1960 garages. Many Van Nuys garages built before 1960 have unreinforced masonry or inadequate anchors that trigger costly retrofits once the structural engineer stamps the plan. We inspect the stem wall and slab on the first visit so you’re not surprised at permit time.
- Fire-flow and hydrant tests on dead-end streets. Lots on dead-end streets or near the Van Nuys Airport flight path often fail water pressure and hydrant spacing requirements. That means an on-site water tank or main upgrade before LADBS signs off, which can add $5,000 to $15,000 to the project.
- Title 24 solar-ready and cool-roof mandates. The Los Angeles Green Building Code requires solar-ready and cool-roof compliance when the existing garage roof is reused. If the roof doesn’t meet the standard, plan-check stalls and material costs climb. We run the solar assessment during design so it never holds up your permit.
- Ceiling height under low-pitch roofs. A garage ceiling under 7 feet 6 inches won’t pass LADBS habitability review. On 1950s tract homes in Van Nuys, that often means reframing the roof or dropping the slab, both of which are expensive fixes that should be priced before you commit.

FAQs About Garage Conversion Contractor in Van Nuys
Yes, if your street has undersized 2-inch water mains or your lot sits on a dead-end street near the Van Nuys Airport flight path, LADBS will require a fire-flow and hydrant test before plan approval. The test itself is quick, but the fix, whether a water tank or a main upgrade, adds 4 to 8 weeks to the permit phase. Call (361) 315-4177 and we’ll check your street’s hydrant spacing on the first visit.
Sometimes. If the existing slab and stem wall pass a structural engineer’s review and meet current LADBS seismic requirements, we can build on the existing pad. Pre-1960 garages in Van Nuys often have unreinforced masonry that fails review and requires a retrofit or new footings. We’ll know after the engineer stamps the plan, not before.
The LADBS sequence is: plan check, then a foundation and slab inspection, then rough framing, rough electrical, rough plumbing if you’re adding a bath, insulation, and finally the final inspection with LADBS including Title 24 verification. We schedule every inspection and stay on site until it passes. The solar-ready mandate is checked during plan review, so we address it before framing starts.
You can do either. Stick framing is cheaper for simple rectangular garages and gives us more control over ceiling height under low-pitch roofs, which matters a lot on 1950s Van Nuys homes. Panelized systems from Cover, Abodu, or Dvele cut framing time but require crane access and a flat staging area, which is tight on many 5,000-square-foot lots. We’ll price both options and let you decide.
Plan to 5 to 7 months total. Permit and plan-check run 8 to 12 weeks, fire-flow testing if required adds 4 to 8 weeks, framing and finishes run 10 to 14 weeks, and LADBS inspections add another 2 to 4 weeks depending on inspector scheduling. We give you a written calendar at contract, and The Garrison Code means we show up in the window we said we would. Call (361) 315-4177 for a project-specific timeline.
