A detached ADU in Citrus typically costs $210,000 – $380,000 depending on site grading, stormwater requirements, and whether you choose prefab or stick-built. A JADU conversion inside an existing home or garage runs $95,000 – $160,000. Those numbers reflect Citrus’s own building division, which enforces drainage and setback rules that neighboring cities often don’t. Reed Calloway, who leads Fielding ADU Builders, has walked enough Citrus parcels to know where the plan-check snags hide before they become change orders.

Why Citrus Homeowners Choose Fielding ADU Builders
We’re the ADU Builders team inside the Garrison Partners family, and we’ve been building to The Garrison Standard since 2006. For Citrus homeowners, that means one thing up front: a written price before any work starts, and a written one-year guarantee when the job is done. If something fails inside that year, we come back and fix it at no charge. No exceptions, no fine print.
Our crews arrive background-checked and in uniform. You know who’s on your property. Dispatch is coordinated from our Los Angeles office, but the people swinging hammers in Citrus are local to the San Gabriel Valley and know what a sloped grove lot off North Grand Avenue or a mid-century rancher near Citrus Avenue actually requires. We don’t send a generic crew to guess at your site.
Reed Calloway built this operation around a simple code: show up in the window, price in writing, build by the book, leave it clean, stand behind it for a year. Citrus homeowners who’ve been burned by a contractor who moved the price at the door or left the permit board blank tend to appreciate that.
Detached ADU in Citrus
A detached ADU in Citrus is a standalone living unit built in your backyard, separate from the main house. On most Citrus lots, you’re looking at $210,000 – $380,000 all-in before permit fees, and the biggest variable is your site’s grading and drainage path. Citrus sits in the San Gabriel Valley’s groundwater-dependent zone, so a detached ADU here typically needs engineered stormwater retention or a drywell instead of simple downspout discharge. That’s a design detail our competitors’ template plans often miss, and it’s one of the first things Citrus plan check flags.
Site Grading and Stormwater
If your lot slopes toward a neighbor’s property or into a swale, the foundation has to be stepped and the drainage routed properly. We price that into the written quote before work starts. You should never discover a $15,000 drywell mid-project because the plan checker caught what the salesperson’s template missed.
Prefab vs. Stick-Built Shells
We install prefab platforms from Abodu, Cover, and Dvele, and we also build conventional units with James Hardie siding. On a flat Citrus lot, a prefab shell can shave weeks off the calendar. On a sloped grove lot, the crane path and pad elevation have to be confirmed before the factory releases the shell. Order first and check later is how homeowners end up with a factory-set base plate that doesn’t fit a stepped foundation.
JADU in Citrus
A JADU in Citrus converts space already inside your home’s footprint, usually a garage or a bonus room, into a rentable unit with its own entrance. These run $95,000 – $160,000 in Citrus, and that lower number comes from using existing walls, roof, and foundation. But do not price it on the same fee schedule as a detached ADU. Citrus treats JADU conversions under a different permit track, with separate plan-check and inspection milestones.
Garage Conversions and Separate Permits
We just wrapped a project on a sloped citrus-grove lot off North Grand Avenue where the family pulled a separate JADU permit for their converted garage while we built a 640 sq ft detached ADU on the same parcel. Two units, two permit tracks, one written price for the whole job. The garage JADU needed its own egress, its own electrical subpanel, and its own inspection window. A contractor who lumps it into the ADU line item is guessing.
What a JADU Actually Requires
A legal JADU in Citrus needs a separate entrance, a small kitchen, and a bathroom. The existing structure has to meet current code for electrical and ventilation. If your garage was built before 1990, the slab may need moisture testing before we quote the conversion. That test tells us whether we’re laying flooring or excavating.
Trusted Brands We Service in Citrus
We build with Abodu, Cover, and Dvele prefab shells, plus conventional framing with James Hardie siding. If you already own or are considering a prefab unit, we handle the local side: soil reports, stepped foundations, crane scheduling, utility tie-ins, and Citrus’s stormwater sign-off. We don’t just set a box on your lot. We make it legal and buildable in Citrus, which means dealing with the city’s grading and drainage requirements before the shell ever shows up. For Citrus homeowners researching Abodu or Boxabl online, that’s the piece the factory can’t do for you.
Common ADU Builders Problems We See in Citrus Homes
- Drainage flags on otherwise solid plans. Citrus’s building division enforces stormwater retention closely because the area sits in a groundwater-dependent zone. Plans that pass county pre-screen often get rejected on local grading details.
- Prefab shells ordered before the site is checked. Hillside lots near North Grand Avenue or the older streets east of Citrus Avenue often need stepped foundations. A factory-set base plate doesn’t accommodate three steps in the stem wall.
- JADU pricing modeled on detached ADU fees. Citrus runs JADU conversions through a separate permit track. If your quote doesn’t show separate plan-check and inspection line items, it’s not honest.
- Old garage slabs failing moisture tests. Garages built before 1990 in Citrus frequently sit on slabs without vapor barriers. We test before we quote so you’re not handed a change order after demolition.
Pricing for ADU Builders in Citrus, CA
Detached ADUs in Citrus land between $210,000 and $380,000. JADU conversions run $95,000 to $160,000. What moves the number: lot slope, soil condition, stormwater retention, utility trenching distance, and whether you choose a prefab shell or stick-built framing. A flat lot with a short trench run and a standard drywell sits at the lower end. A sloped grove parcel requiring a stepped foundation, engineered drainage, and a longer sewer lateral sits at the higher end. The written price we give you before any work starts is the number on the final invoice, period. Call (361) 315-4177 for a free estimate on your specific Citrus parcel.

FAQs About ADU Builders in Citrus
Yes. Citrus runs JADU conversions through a different permit track than detached ADUs, with separate plan-check fees and inspection milestones. A detached ADU needs full site, grading, and stormwater review. A JADU inside existing square footage skips the grading review but still needs plan check for egress, electrical, and ventilation. Your written quote should show both as separate line items if you’re building both units. Call (361) 315-4177 and we’ll map out exactly which permits your parcel triggers.
Citrus sits in the San Gabriel Valley’s groundwater-dependent zone, so the city’s building division requires engineered stormwater retention or a drywell on most detached ADU projects. Neighboring cities may allow simple downspout discharge. Citrus plan checkers specifically look at where your runoff goes and whether it affects adjacent parcels. We include drainage design in the written quote before submittal, so the flag doesn’t become a surprise. For an exact site read, call (361) 315-4177.
Yes, but the crane path and pad elevation have to be confirmed before the factory releases the shell. Sloped lots in Citrus often need stepped foundations, and factory-set base plates don’t account for elevation changes. We handle the soil report, stepped stem wall, and crane scheduling so the prefab unit fits the site instead of the other way around. Call (361) 315-4177 to get your lot evaluated before you order a shell.
Most detached ADUs in Citrus run 7 to 11 months from plan submittal to final inspection. Citrus’s own building division handles plan check locally, which moves faster than LA County in some cycles and slower in others depending on stormwater review backlog. Prefab shells can cut 4 to 6 weeks off framing time once the foundation is approved. We give you a written calendar with the quote. Call (361) 315-4177 for a realistic schedule on your specific parcel.
The three things that move the number mid-project in Citrus are soil conditions, utility trenching depth, and stormwater retention requirements discovered during excavation. That’s why we walk the lot, test the soil, and review the city’s drainage expectations before we hand you a written price. The number you approve on day one is the number on the final invoice. No change orders. Call (361) 315-4177 to get your written quote started.
