ADU Company in Citrus, CA
Building an ADU in Citrus means navigating LA County’s unincorporated permit system, not a city planning department. Most Citrus lots were carved from former citrus groves in the 1950s – 1970s and sit on 8,000 – 12,000 square feet, giving families room for a detached unit or garage conversion that wouldn’t fit on tighter lots in neighboring cities. We’re Seedling ADU Builders, and our crews work with these county-specific requirements regularly. Call (707) 383-5338 to talk through your lot and get a written estimate.
Why Citrus Homes Are Different
Citrus developed as an unincorporated community, which means every ADU permit runs through LA County Building & Safety and, for discretionary items, the Department of Regional Planning downtown. There’s no city hall to call, no local planning counter, and that surprises most homeowners who start by searching for “City of Citrus.” We’ve seen families lose weeks trying to find a municipal contact that doesn’t exist.
The housing stock reflects this history: single-story ranch tracts on generous lots, many with detached single-car garages from the 1960s that make natural JADU candidates. The foothill terrain matters too. Portions of Citrus fall within LA County Fire Hazard Severity Zones, where ADU construction requires ember-resistant vents, Class A roofing, and ignition-resistant siding. These aren’t optional upgrades; they’re inspection checkpoints that add cost and timeline. A project near the San Gabriel Mountain interface faces steps that a comparable build toward the valley floor simply doesn’t.
Our Main Citrus Services
Citrus homeowners typically call us about three projects: expanding the main house, converting an existing garage, or building a new detached ADU on the lot.
Home Addition Contractor in Citrus
A home addition in Citrus often means extending a 1950s – 1970s ranch to add a bedroom, expand the kitchen, or create a connected in-law suite. We work with the original slab conditions common in this era and coordinate LA County structural checks when we’re tying into aged framing. Our crews use shoe covers and drop cloths inside the home, and we send a clean-up photo before leaving each day. Home Addition Contractor in Citrus

Garage Conversion Contractor in Citrus
Garage conversions in Citrus frequently start with those detached single-car structures from the 1960s. The county treats these as JADU candidates if they’re within the main dwelling’s setback envelope, or as full ADU conversions if detached. Fire zone requirements apply here too, especially for new electrical and ventilation penetrations. We handle the LA County submittal and inspection sequence so the project doesn’t stall between agencies. Garage Conversion Contractor in Citrus
