Get your free estimateFast, Reliable ADU Builders Across Inglewood
Most Inglewood ADU projects we scope fall into one of two buckets: a detached unit in the rear yard, or a JADU carved out of an existing garage or interior space. On the older R-1 lots that dominate neighborhoods like Morningside Park and Inglewood Knolls, the difference between a clean build and a stalled one usually comes down to lot coverage, rear setbacks, and whether the existing garage is worth converting. We handle that scoping work up front, before you spend a dime on plans. Call (361) 315-4177 and we’ll walk your specific lot, your specific constraints, and a real number for the work.
We are ADU Builders who work in Inglewood week in and week out. That means we know the plan check rhythm at Inglewood City Hall, which utility coordination slows a project down, and what a realistic calendar looks like on a 5,200 sq ft lot with a 1941 bungalow on it. No catalog pricing. No surprise re-scopes. A written price before any work starts, and a one-year written guarantee after it’s done.
Key Takeaways:
- Inglewood ADU work ranges roughly $180 – $420 per sq ft depending on build method, with JADUs typically landing lower than detached units.
- City-specific ADU ordinances layer on top of state law, so setback, lot coverage, and alley access rule the plan set.
- Every project gets a written price before work begins, covered by the 365-Day Done Right Promise.
- We work with prefab platforms like Abodu, Cover, and Dvele, plus conventional James Hardie-clad construction.

Why Fielding ADU Builders Is Inglewood’s Preferred ADU Builders Company

Fielding ADU Builders is part of the Garrison Partners family, which has been building to The Garrison Standard since 2006. Reed Calloway leads our team, and the standard he enforces is simple: show up in the window, put the price in writing, build by the book, leave the site clean, and stand behind the work for a full year. That’s The Garrison Code, and it’s the same in Inglewood as it is anywhere else we work.
Homeowners in Inglewood call us for a specific reason: they’ve already been through a contractor who moved the price at the door or left the permit board blank. Our answer is a written price before any work starts. Not a verbal ballpark. Not a range that balloons at framing. A line-item number you approve before a single nail is driven. If the work fails inside that first year, we come back and correct it at no charge. That’s written down too.
Every crew member on an Inglewood job is background-checked and uniformed. You know exactly who is on your property. Dispatch runs from the brand’s Los Angeles office, but the crews serving Inglewood know the city’s older blocks, its alley-loaded lots, and its inspection cadence. And when you call, a live person answers. Every time. No voicemail queue at midnight.
Detached ADU in Inglewood
A detached ADU in Inglewood is a separate living unit built in the rear yard of an existing single-family property, with its own entrance, kitchen, bathroom, and addressable utility service. On Inglewood’s older R-1 lots, which commonly run 5,000 to 6,000 sq ft with 1920s to 1940s homes, the rear setback, lot coverage, and alley access often determine where that unit can sit and how big it can be. A standard detached ADU in Inglewood runs $220 – $420 per sq ft before permit fees, with one-bedroom units typically landing between $180,000 and $320,000 all-in.
The single most common re-scope we see in Inglewood is a plan-catalog price that never accounted for rear coverage. If an existing garage already eats into the allowed rear lot coverage, the new detached unit may need a smaller footprint or a variance. We check that before quoting, so the number we hand you is the number you build to.
Rear Setback and Alley Access Reality
Inglewood’s ADU ordinance layers local setback rules on top of state law. A detached unit must clear the rear property line by the city’s standard, unless you secure a setback variance. If your lot backs to an alley, that access point shapes how we bring in materials, where we trench utilities, and whether a modular delivery has room to set the unit. We flag all of this in the scoping call, not after plan check.
Utility Service and Trenching
A detached ADU in Inglewood needs its own electrical service, water lateral, and sewer connection. On older lots, the existing sewer lateral may sit shallow or route under the proposed slab. We coordinate with Southern California Edison and the city’s utility desk as one combined submittal, so the trenching and inspections run on a single schedule instead of piecemeal stops and starts.
JADU in Inglewood

A JADU in Inglewood is a junior accessory dwelling unit created inside the footprint of the existing single-family home, capped at 500 sq ft, and required to share either a bathroom or an efficiency kitchen with the primary residence. A garage conversion JADU in Inglewood typically runs $120,000 – $200,000 including finishes, depending on whether the garage slab can stay or needs structural work. Interior JADUs carved from spare rooms run lower, often $80,000 – $140,000.
JADUs are not smaller versions of detached ADUs. In Inglewood, the JADU is owner-occupancy-tied, meaning the homeowner must live on the property either in the main house or the JADU. Miss that and the plan fails plan check. We see it happen when a homeowner designs a JADU with a full second kitchen. That fails too. A JADU shares systems with the primary home; it’s a different build than a detached unit with its own address and meter.
Garage Conversion JADUs on Older Inglewood Lots
Much of Inglewood’s single-family housing stock was built before 1950, and the detached garages that came with those homes are often single-car structures with aging slab foundations. Converting that garage into a JADU means upgrading the slab if it’s cracked or uninsulated, adding proper egress windows, and tying the unit into the main home’s existing bathroom or creating an efficiency kitchen that meets Inglewood’s JADU requirements. We scope the garage before we quote, checking the slab, the roof structure, and the distance to the main house for the shared utility connection.
Owner-Occupancy and Permit Sequencing
Inglewood enforces the JADU owner-occupancy covenant. It runs with the property, not the person, so a future buyer inherits that condition too. We explain this in plain language before you commit, because it affects resale expectations. We also sequence the JADU permit so that any electrical panel upgrade or main-house plumbing tie-in lands in the same inspection window as the unit finish work.
Trusted Brands We Service in Inglewood
We install and finish Abodu, Cover, and Dvele prefab and panelized units, and we build conventional ADUs with James Hardie siding and standing-seam roofs. That’s not a marketing line; it’s the reality of matching the right build method to the right Inglewood lot. A tight rear yard off Crenshaw Boulevard may favor a panelized unit where the factory builds the shell and we handle foundation, utilities, and finish. A wider lot near Centinela Avenue may support a conventional stick build with Hardie lap siding that matches the existing 1930s house. We keep local suppliers on speed for Hardie trim, panelized touch-up materials, and the common utility components, so warranty callbacks and finish punch lists move fast.
Common ADU Builders Problems We See in Inglewood Homes
- Quoting off a catalog price without checking rear coverage. The most frequent re-scope on Inglewood’s older R-1 blocks happens when a customer gets a per-square-foot quote for a detached ADU, and nobody checked whether the existing garage already consumes the allowed rear lot coverage. A smaller unit or a variance changes the number. We check before we quote.
- Treating a JADU like a smaller detached ADU. JADUs in Inglewood are capped at 500 sq ft, owner-occupancy-tied, and must share a bathroom or an efficiency kitchen with the main home. Adding a full second kitchen to a JADU design fails plan check, and that mistake costs weeks.
- Assuming a prefab panelized shell shortens the calendar. Boxabl, Mighty Buildings, Plant Prefab, and Dvele units still need foundations, utility trenching, SD/utility coordination, and the full Inglewood inspection sequence. A factory delivery date that front-runs the permit just ties up the module and the deposit.
- Ignoring alley access on rear-yard detached units. On Inglewood lots that back to alleys, access shapes how we bring in materials and whether a modular delivery can even set the unit. We walk the access route during scoping, because a crane that can’t reach the pad is a five-figure problem.
Pricing for ADU Builders in Inglewood, CA
A detached ADU in Inglewood runs $220 – $420 per sq ft before permit fees. A one-bedroom, 500 sq ft unit lands between $180,000 and $320,000 depending on site work, foundation, utility runs, and finish level. A garage conversion JADU runs $120,000 – $200,000. An interior JADU carved from existing space runs $80,000 – $140,000.
What actually moves the number in Inglewood: rear lot coverage and setbacks, alley access, whether the existing garage slab can stay or needs replacing, the length of the utility trench from the street or alley to the unit, and the finish package you choose. A prefab shell from Abodu or Cover doesn’t eliminate those site costs; it changes where they’re spent. We put all of this in writing before you approve anything.

FAQs About ADU Builders in Inglewood
We walk your lot, check rear setback, rear coverage, alley access, and whether the existing garage can convert. Then we put a written price in front of you before any work starts.

Call (361) 315-4177 and we’ll start with the walk.
A detached ADU runs $220 – $420 per sq ft before permits; a JADU runs $80,000 – $200,000 depending on scope. The number moves on rear lot coverage, setback variances, alley access, whether the garage slab stays or goes, utility trench length, and finish level. We quote all of that in writing before you commit. Call (361) 315-4177 for an exact number on your lot.
Yes, on many Inglewood R-1 lots you can build a JADU inside the existing home footprint plus a detached ADU in the rear yard, provided the combined scope clears the city’s rear coverage and setback rules. We recently framed a detached ADU behind a converted garage JADU on a corner lot off West Boulevard near Morningside Park, tied both to a single upgraded service, and walked the whole scope through Inglewood plan check as one submittal. That got two rentable units off one permit cycle.
They can save framing time on site, but they don’t shorten the city’s process. The foundation, utility trenching, Southern California Edison and SD coordination, and the Inglewood inspection sequence still set the calendar. A factory delivery date that front-runs the permit just ties up the module and the deposit. Call (361) 315-4177 and we’ll tell you honestly which build method fits your lot and your timetable.
It depends on the scope. A garage conversion JADU and a new detached ADU can often run as one combined submittal if they share an upgraded electrical service and the plan set covers both scopes together. If the garage conversion includes structural changes to the slab or roof, that scope folds into the same permit package. Call (361) 315-4177 and we’ll tell you exactly how Inglewood plan check will read your project.
