Fast, Reliable Garage Conversion ADU Across Inglewood
A garage conversion ADU in Inglewood typically runs $95,000-$165,000 all-in, from measured drawings through final inspection, depending on whether your garage is attached, detached, or a carport and whether it needs full electrical and sound-attenuation upgrades. Most Inglewood conversions take 4-6 months to permit and build, with our Garage Conversion ADU team coordinating every step from our Los Angeles office. Call (213) 329-7167 to schedule your free estimate - every project gets a written price before any work starts, per Haven Standard Clause 1.
We’ve worked the Inglewood grid from Morningside Park down to Century Boulevard and west toward La Brea as part of our ADU Design & Permitting in Inglewood. The housing stock here is consistent: 1940s-1960s stucco bungalows and small California ranches on 5,000-7,000 sq ft lots, most with detached single-car garages built to 1950s standards. That predictability is useful - until you open the walls and find what 70 years of coastal moisture and outdated code have left behind.
Why Ellery ADU Studio West Hollywood Is Inglewood’s Preferred Garage Conversion ADU Company
Nadia Ellery founded Ellery ADU Studio in 2015, the same year California’s ADU laws shifted statewide, and we’ve since designed, permitted, and built more than 900 ADUs - every one with a written price before work started and a documented photo record when work was complete. Our crews serve Inglewood directly from our Los Angeles office, with scheduling and permit coordination handled locally.
Inglewood homeowners come to us after receiving quotes that seemed low until the walls opened. The difference is usually two line items our competitors missed: the full electrical service upgrade that 1950s garage wiring demands, and the STC-rated glazing plus mechanical ventilation required inside the LAX 65 dB CNEL noise contour. We check both before we quote.

Our Garage Conversion ADU Services in Inglewood
Detached Garage Conversion
Detached single-car garages dominate Inglewood’s residential blocks, especially between Prairie Avenue and Inglewood Avenue near Hollywood Park. These structures were built as storage, not housing: uninsulated CMU or wood-frame walls, 60-100 amp sub-panels, no plumbing rough-in, and slabs poured without moisture barriers. Converting one to a permitted ADU means sistering undersized framing, upgrading to 200-amp service, and routing new water, sewer, and gas lines from the main house. In the LAX noise contour, we also spec STC-rated windows and an HRV or ERV for mechanical fresh-air ventilation - operable windows alone won’t pass inspection.
Attached Garage Conversion
Attached garages in Inglewood’s older Morningside Park blocks share a wall with the main house, which simplifies utility tie-ins but complicates fire separation and sound transmission. California building code requires a one-hour fire-rated assembly between dwelling units, plus independent HVAC so garage fumes don’t migrate. We handle the firewall design in our permit set, not as a change order later.
Garage Partition & Bathroom Add
Some Inglewood homeowners want to keep garage parking and add only a studio or bathroom suite. We partition the space with a rated firewall, run new plumbing through the slab or overhead, and ventilate the new habitable zone independently. Every fixture location is drawn and permitted before we cut concrete.
Garage JADU
A Junior ADU - under 500 sq ft, sharing bathroom or kitchen facilities with the main house - fits Inglewood’s smaller garages where a full ADU would crowd the lot. The JADU path has relaxed parking and setback rules, but it still needs permitted electrical, and if it’s inside the noise contour, the same STC and mechanical ventilation requirements apply. We model both ADU and JADU options in our first design pass so you can compare.
Carport Conversion
Carport conversions in Inglewood face a specific hurdle: most carports lack any slab suitable for enclosed living, and many sit on unpermitted footings or no footings at all. We assess the existing structure for enclosure potential and, if needed, design a replacement slab and wall system as part of the same permit set.

AfterTrusted Brands We Service in Inglewood
Ellery ADU Studio specifies and coordinates prefab and modular systems within our single-contract model. For Inglewood’s garage conversions, we regularly integrate Tuff Shed structures for detached replacements when the existing garage is unsalvageable, James Hardie siding assemblies for durable exterior cladding in coastal air, and Abodu units where the garage site allows a full teardown-and-replace. Every brand selection is documented in the permit set and locked at the written price - no substitution surprises.
Common Garage Conversion ADU Problems We See in Inglewood Homes
- Cloth-insulated wiring on overloaded sub-panels. Open a 1950s Inglewood garage and you’ll likely find fabric-wrapped conductors feeding a 60-amp panel - completely inadequate for modern habitable space and a fire hazard under current code. We price the 200-amp service upgrade in the original quote, not as a mid-project shock.
- LAX noise contour compliance gaps. Contractors from Hawthorne or Gardena routinely spec standard windows and natural ventilation for Inglewood garages that sit inside the FAA’s 65 dB CNEL line. Those units fail inspection. We check LA County noise contour maps before we draw a single window schedule.
- Dry-rotted sill plates and slab moisture intrusion. Decades of ponding at slab edges, especially on north-facing garages with poor drainage, destroy the mud sill and bottom plates. We inspect with moisture meters during our first site visit and write structural repair allowances into the contract.
- Undersized framing for roof loads. Many Inglewood garages were built with 2×4 rafters at 24 inches on center - fine for a garage, insufficient for a ceiling insulated to R-38 with drywall below. We engineer the structural upgrade and permit it as part of the original set.

FAQs - Garage Conversion ADU in Inglewood
Check your parcel on the LA County Airport Land Use Commission noise contour map: if your property sits inside the 65 dB CNEL line, California building code mandates STC-rated glazing and mechanical ventilation for any new habitable space. We verify this during our first site visit and spec the correct assembly in our permit set so your inspection passes the first time. Call (213) 329-7167 and we’ll check it before you commit to anything.
Most Inglewood garages were wired in the 1950s with 60-amp sub-panels and cloth-insulated conductors - adequate for a garage door opener and a light bulb, but not for a kitchen, bathroom, and HVAC unit. Modern ADU code requires a 200-amp service, dedicated circuits, and GFCI/AFCI protection throughout. We include this upgrade in every quote where our site visit confirms the old wiring is present. Call (213) 329-7167 for an exact assessment - estimates are free.
We stop work, document the condition with photos, and submit a written change order with a fixed price for the repair. Under Haven Standard Clause 5 (No Surprises), you approve every dollar before we touch it. Our contracts include structural and electrical repair allowances based on what we find during inspection, so most common issues are already priced in. Call (213) 329-7167 to review how our allowance system protects your budget.
Yes - both are permitted under Inglewood’s ADU ordinance, which follows California state law. A JADU must be under 500 sq ft and can share kitchen or bathroom facilities with the main house; a partition creates two separate spaces within the existing garage footprint, each with its own use. Both paths still require permitted electrical, and if you’re inside the LAX noise contour, the same STC and mechanical ventilation rules apply. Call (213) 329-7167 and we’ll model both options with real square footage and real prices.
Contractors based in Hawthorne, Gardena, or Torrance frequently miss two Inglewood-specific cost drivers: the mandatory sound-attenuation package inside the LAX noise contour, and the near-certain electrical service upgrade on 1950s garage stock. Their initial quote omits both. Once walls are open and the inspector flags the missing STC glazing or the 60-amp panel, the homeowner receives change orders that add $15,000-$30,000. We price both conditions upfront, before you sign. Call (213) 329-7167 for a written quote that includes everything your garage actually needs.
