A room addition in Citrus, CA typically runs $180 – $320 per square foot before permit fees, and the county review process often adds 4 – 8 weeks compared to incorporated cities nearby. Most Citrus additions we scope fall between 350 and 600 square feet, which puts the realistic budget at $65,000 – $190,000 depending on foundation work, electrical upgrades, and whether you’re tying into the existing house or converting a detached structure. Call (559) 238-9583 for a written price before any work starts.
We work Citrus lots every week. Not West Covina lots or Diamond Bar lots. Citrus lots. That matters because Citrus sits in unincorporated Los Angeles County, which means county zoning, county septic reviews, and county drainage rules govern your addition. A contractor who bids Citrus without knowing the difference between county and city code will miss something that stops the project cold. We don’t. Reed Calloway has built his team around the specific conditions of this unincorporated pocket, from Citrus Avenue down to the acreage parcels east of Barranca.
Why Fielding ADU West Covina Is Citrus’s Preferred Room Addition Contractor Company
Fielding ADU West Covina operates as an independent member of the Garrison Partners family, founded in 2006. We build additions and ADUs under The Garrison Standard: show up in the window, price in writing, by the book, leave it clean, stand behind it for a year. That standard matters more in Citrus than most places, because county permitting adds layers a homeowner can’t see from the street. Our Room Addition Contractor team has worked through enough Los Angeles County plan checks to know which drawings get flagged, which septic setbacks get challenged, and which drainage plans pass on the first submittal.
Citrus customers call us for specific reasons. The written price goes in your hand before a single nail is driven, and that number doesn’t move unless you change the scope. Every crew member is background-checked and arrives in uniform, so you know exactly who is walking your property. And someone answers the phone at (559) 238-9583 at noon or midnight, every day.
In Law Suite Builders in Citrus
In Law Suite Builders in Citrus handle a specific job: adding a self-contained living space inside or attached to your primary home, with its own entrance, bath, and usually a small kitchen. On Citrus’s 5,000 – 7,500 square foot R-1 lots, an in-law suite is often the only way to add real living space without fighting the county’s 5-foot side and 10-foot rear setbacks. A junior ADU tucked inside the existing footprint avoids the setback trigger entirely, which can cut permitting time in half.
What In Law Suite Builders Actually Do Here
An in-law suite in Citrus means carving 350 – 600 square feet out of an existing floor plan or extending into a garage footprint. The work includes framing, electrical, plumbing, a separate entrance, and usually a mini-split HVAC line. Expect $75,000 – $145,000 on a typical Citrus rancher when the space stays within the existing footprint.
Why Citrus Homeowners Choose an In-Law Suite Over a Detached ADU
Detached ADUs on county lots trigger full setback review, sewer capacity checks, and often grading plans. An attached in-law suite doesn’t. For a Citrus homeowner with aging parents, an adult child, or a rental-income goal, the in-law suite gets you usable square footage faster and cheaper. The trade-off is privacy, not legality. Both routes get a written price from us before work begins.
ADU Conversion in Citrus
ADU Conversion in Citrus is the fastest route to legal living space, and in this unincorporated county pocket it’s usually the right one. Citrus’s housing stock is dominated by single-story 1950s – 1970s ranchers with detached garages and carports that were never built to house people. Converting that garage into an ADU runs $120,000 – $220,000 when it includes structural upgrades, a new service panel, insulation, and full plumbing rough-in. A carport conversion can run lower, around $90,000 – $150,000, but only if the slab has proper footings. Many don’t.
Detached Structure Conversion Details
Most Citrus garages sit on slabs without footings deep enough for a dwelling. County code requires that we verify the foundation before we pull permits. If the slab fails, we pour new footings and tie the structure down properly, which is exactly the kind of item we put in the written price before you sign. No change orders at the door.
Junior ADU Conversion Inside the Home
A junior ADU (JADU) comes from converting an existing bedroom, den, or attached garage space into a legal unit with its own entrance and efficiency kitchen. In Citrus, a JADU frequently avoids septic and sewer expansion requirements because it doesn’t add new waste fixtures. Budget $60,000 – $110,000 in most Citrus homes, less when plumbing stacks are close by.
Trusted Brands We Service in Citrus
Fielding ADU West Covina works with the prefab and modular platforms Citrus homeowners are already researching: Abodu and Cover for factory-built ADUs delivered on-site, and Dvele for high-performance panelized construction. On conventional additions we build with James Hardie siding because it holds up to Citrus’s high UV exposure without warping or fading the way wood does. We don’t push one system on every job. We match the method to your lot, your foundation, and your budget, then put the whole thing in writing.
Common Room Addition Contractor Problems We See in Citrus Homes
- County jurisdiction confusion. Citrus is unincorporated Los Angeles County. Contractors who assume city permits apply miss septic setbacks, well distances, and county drainage rules, and that’s how acreage lots end up with stop-work orders.
- Undersized electrical panels. The original 100-amp panels on 1950s – 1970s Citrus ranchers fail inspection for new room additions. You need 200 amps before the county signs off, and that’s a line item we price upfront, not a surprise later.
- Cast-iron waste lines and hard water. Citrus water is hard, and it shortens the life of new plumbing components unless a softener is planned. When we tie into original cast-iron, we check for scale buildup and often recommend a repipe section rather than patching.
- Detached carport and garage footings. Adding a room over or around an old carport slab in Citrus without structural upgrades leads to cracked slabs and unpermitted work. We inspect footings before we quote, so the number you approve covers what’s actually needed.

FAQs About Room Addition Contractor in Citrus
Septic and well setbacks on Citrus acreage determine where your addition can physically sit, and a room addition that increases bedroom count usually triggers a county septic system capacity review and a minimum distance from the well of at least 100 feet in most cases. We verify all setbacks and tank locations before we scope the job. Call (559) 238-9583 and we’ll check your parcel.
Because Citrus has clay-heavy soil that expands in winter and cracks slabs and stem walls when water pools against them. County drainage rules require that runoff be directed away from the foundation, and a grading plan is how the county verifies that before issuing the permit. We’ve regraded side yards on Citrus Avenue properties specifically to fix this. Call (559) 238-9583 for a free site look.
Yes, and it’s often the smartest move on a small Citrus lot because the garage footprint already exists and avoids the county’s 5-foot side and 10-foot rear setbacks. What you’ll need is a foundation check, likely a new footing pour, and full insulation and electrical. Budget $120,000 – $220,000. We’ll write the real number for your garage specifically.
Most 1950s Citrus ranchers carry 100-amp panels, and a new room addition with its own mini-split, lighting, and outlets will fail county inspection without a 200-amp service upgrade. That upgrade is a line item in our written price, typically $4,000 – $8,000 depending on the condition of the existing service. Call (559) 238-9583 and we’ll tell you what yours needs.
Citrus water is hard enough to scale up new pipes and fixtures within a few years, so we spec the plumbing rough-in for longevity and often recommend a whole-house softener when we tie into original cast-iron. If the existing waste line is heavily scaled, we price a repipe section rather than a patch. It’s all in the written estimate.
