Citrus is an unincorporated pocket of Los Angeles County wedged between Covina, Azusa, and Glendora, and the housing stock here tells you exactly what kind of ADU work we do most. Think 1950s and 1960s single-story ranchers on generous lots, many of them never touched since the original build. That means old electrical panels, slab foundations that have settled, and backyards that are actually big enough for a detached unit. Fielding ADU Builders handles the whole range: garage conversions, room additions, and full backyard ADUs. If you’re weighing your options, call (361) 315-4177 and we’ll give you a straight read on what your lot can handle.
Why Citrus Homes Are Different
Most of Citrus sits on flat, alluvial ground that drains toward the San Gabriel River channel, which sounds boring until the first real rain of the season arrives. What matters for ADU work is how the older homes were built: pier-and-beam sections give way to slabs without a step down, so tying a new foundation into an existing one takes real care. We see a lot of homes in the citrus-belt streets south of the 210 where the original sewer lines are cast iron and the panel is a 100-amp pushmatic from the Nixon administration. That changes scope on a garage conversion fast. Add in the county permitting path rather than a city one, and the timeline here runs a little different than in incorporated Covina or West Covina. Homeowners who know Citrus know that the county wants its paperwork square before a single footing goes in.
Our Main Citrus Services
Three jobs dominate the calls we get from Citrus homeowners. Here’s how each one works on the ground, and a link to the dedicated page for that service in Citrus.
Room Addition Contractor in Citrus
A room addition here usually means extending a rancher’s footprint into the side yard or punching out the back wall to add a family room or primary suite. The Citrus-specific part is the foundation work: matching a new slab to a 60-year-old one without creating a crack line you’ll see in the drywall six months later. We handle the county permit drawings, the tie-in to the existing roof line, and the electrical service upgrade if your panel can’t carry the new load. The Garrison Standard applies here in full: written price before work starts, and a one-year written guarantee when we’re done. Room Addition Contractor in Citrus
Garage Conversion Contractor in Citrus
Citrus garages from the 1950s and 60s are often detached, which is good news: the county treats a detached conversion with a lighter touch than an attached one, and you don’t have to tie into the house foundation. The bad news is the slab. Many old garage slabs in this area were poured thin, so we commonly saw-cut and repour before framing walls. Electrical, insulation, drywall, and a mini-split for climate control round out the job. You get a written price on day one, and the full year of the Done Right Promise when the final inspection clears. Garage Conversion Contractor in Citrus
ADU Builders in Citrus
A detached backyard ADU on a Citrus lot is often the highest-value move per square foot. The lots here can run 6,000 to 8,000 square feet, which leaves real room for a junior unit at the back of the property. We work conventional stick-frame builds, and we’re also fluent with prefab platforms like Cover and Dvele when the goal is a faster build with less site disruption. County setbacks, utility trenching from the street, and the grading plan are the parts that trip up homeowners going it alone. We handle all of it, with the price locked in writing before anything is ordered. ADU Builders in Citrus

What pushes a Citrus price up is usually the condition of what’s already there: old panels, failed slab sections, and sewer laterals that need lining. What doesn’t push it up is us changing the number mid-job. The price we hand you in writing is the price on the final invoice.
