Call (254) 602-5618 for a free estimate with real numbers before you commit to anything.
Why Lodgewick ADU Builders Is Canoga Park’s Preferred Garage Conversion Contractor Company
We spend our days walking Canoga Park lots, and we know what’s under these homes before we lift a single floorboard. Russ Delmar leads our team, and he’s been clear from the start: our job is to give a Canoga Park homeowner a written price, show up in the window we gave, leave the site cleaner than we found it, and come back if anything fails within the 365-day guarantee period. That’s The Kingswell Way. It’s not a slogan we put on a truck. It’s what we put in the written guarantee on every project.
Canoga Park homeowners have told us about contractors who low-balled the bid on a Rocketdyne-era detached garage, then sent a change order when the LA inspector required a perimeter footing. We don’t do that to people. We price the slab work in the first number. We also answer calls 24/7 with a live person, not a voicemail loop. When you call (254) 602-5618, you get an actual human who can talk about your specific street, your specific garage, and what it’s going to cost.
Garage Conversion ADU in Canoga Park
A Garage Conversion ADU in Canoga Park means turning an existing attached or detached garage into a permitted accessory dwelling unit with its own kitchen, bathroom, entrance, and electrical subpanel. On a 1950s ranch off Sherman Way or Topanga Canyon Boulevard, that almost always starts with foundation work: these garages were poured on thin, unreinforced slabs, and LA building inspectors routinely require slab thickening or a full perimeter pour before framing. A permitted Garage Conversion ADU here runs $110,000 to $165,000 when it includes the foundation correction, a panel upgrade from the original 100-amp service, a properly load-calculated mini-split, and high-R insulation.
Detached Garage to ADU
The detached two-car garages in Canoga Park are some of the best conversion candidates in the entire west Valley. These Rocketdyne-era lots are larger than what you’ll find a few miles east in Reseda or Northridge, which means the ADU can go in without eating your whole backyard. We handle the foundation, framing, insulation, drywall, electrical, plumbing, and finish work as one contract with one written price.
Attached Garage to Living Space
If your garage shares a wall with the house, the conversion path is different. We’re still dealing with the same slab issues, but the tie-in to the existing roofline and the fire-rated separation wall become the focus. These conversions run $95,000 to $140,000 in Canoga Park depending on how much of the original garage framing can be reused.
Garage Apartment Conversion in Canoga Park
A Garage Apartment Conversion in Canoga Park takes a detached garage and turns it into a rentable studio or one-bedroom unit, often for a tenant or a family member who needs their own door. The big difference from a simple finishing job is habitability: a Canoga Park apartment ADU has to stay livable through the 108 – 112°F stretches that hit this part of the Valley every July and August. That means a dedicated mini-split with a proper load calculation, radiant-barrier roof decking, and high-R wall insulation, not a window unit plugged into the old garage circuit. A Garage Apartment Conversion here runs $105,000 to $155,000, and rental income potential for a one-bedroom in Canoga Park makes these projects pencil out for a lot of homeowners.
Garage to Bedroom Suite
Some Canoga Park homeowners just need a quiet bedroom with a half bath for an aging parent or an adult child. We’ve done these as simpler conversions without a full kitchen, which keeps the price closer to $85,000 to $110,000. The foundation work and electrical upgrade still apply.
Garage to Rental Unit
When the goal is a permitted, rentable ADU with its own address and utility meters, we build it to LA’s current ADU standards from day one. That includes the fire-rated separation, the independent electrical subpanel, and the insulation levels that keep the unit rentable through Canoga Park’s multi-day heat events. The written guarantee covers the whole build for 365 days.
Trusted Brands We Service in Canoga Park
We stock and work with materials that hold up in Canoga Park’s heat-and-dust conditions. We specify James Hardie siding on converted garages, using stainless fasteners instead of hot-dipped nails, because painted steel and standard galvanized hardware flash rust within two summers in this climate. We also work with leading prefab ADU manufacturers, including Abodu and Dvele, which gives Canoga Park homeowners a faster path to a precision-built unit when site-built doesn’t fit the timeline. For a fully custom garage apartment, we’ll quote a Cover unit as a comparison so you can see the price gap between prefab and stick-built before you decide.
Common Garage Conversion Contractor Problems We See in Canoga Park Homes
- Flat-slab bids that ignore the foundation. The 1950s detached garages here were poured on thin, unreinforced concrete with no perimeter footings. LA inspectors require slab thickening or a full perimeter pour before framing on most conversions. A bid that doesn’t price that work is a change order waiting to happen.
- Standard galvanized fasteners and painted steel window frames. In Canoga Park’s summer swings, these pit and fail fast. We opened a garage off De Soto Avenue and found exactly this spec from a previous bidder. We replaced it with stainless fasteners and marine-grade window frames, which is what the job actually requires here.
- Mini-splits sized on square footage alone. A Canoga Park ADU without a radiant-barrier deck and a proper high-R envelope will not stay cool through multi-day 105°F stretches. We load-calculate the mini-split for the actual heat load, not just the room dimensions.
- Untreated or improperly sealed fence posts and railings. The same heat-and-dust cycle that eats fasteners also wrecks cheap pressure treatment. We use marine-grade finishes and sealed joints on any exterior wood we touch during a conversion.
Pricing for Garage Conversion Contractor in Canoga Park, CA
Here’s what we actually quote in Canoga Park. A basic attached garage to living space conversion with a half bath starts around $85,000. A detached garage to full ADU with kitchen, bath, foundation correction, panel upgrade, and mini-split runs $110,000 to $165,000. A garage apartment conversion set up for rental income lands between $105,000 and $155,000. What moves the number is the slab condition, how much of the original framing can be reused, and whether we’re doing a panel upgrade from the original 100-amp service, which most of these homes need. We give one written price before any work starts, and it doesn’t change at the door. Call (254) 602-5618 to schedule a free estimate.

FAQs About Garage Conversion Contractor in Canoga Park
A Canoga Park ADU costs more because the heat corridor demands a different building spec. We’re installing high-R insulation, radiant-barrier roof decking, and a properly load-calculated mini-split that a coastal property can skip. Plus the 1950s slabs here almost always need foundation work before framing. That’s real added cost, not contractor markup. Call (254) 602-5618 for a written breakdown on your specific garage.
Most of them do, yes. The original Rocketdyne-era garages were poured on thin, unreinforced slabs with no perimeter footing. LA inspectors routinely require slab thickening or a full perimeter pour before framing an ADU. We price this in the first written number so you don’t get a surprise change order.
Because standard galvanized hardware and painted steel window frames fail fast in Canoga Park’s heat-and-dust swings. We’ve pulled standard fasteners out of converted garages that flashed rust within two summers. Stainless costs more on the front end but doesn’t fail within a decade, which is cheaper for you. Call (254) 602-5618 if you want to talk through material specs.
Almost every 1950s home here still has its original 100-amp panel. Adding an ADU with its own kitchen and mini-split circuits almost universally requires a panel upgrade to 200 amps. We include that in our written price. We do not bid the job without it and then change-order you later.
Yes, if it’s built to the right thermal spec. A unit with high-R insulation, radiant-barrier decking, and a properly sized mini-split will hold temperature through multi-day 105°F stretches. A unit built with cheap insulation and a window unit will not. We build the first kind, and we put it in writing.
