Adding an ADU or home addition in Citrus, CA means building on small, established lots where every square foot of yard space counts. Most Citrus homes sit on parcels between 6,000 and 9,000 square feet, which pushes homeowners toward slimmer ADU footprints, garage conversions, and room additions that hug the existing structure. We’re Sutton ADU Builders, and we handle all three here with written pricing before work begins and a 365-Day Done Right Promise on every project. Call (472) 248-8213 and we’ll talk through what your lot can actually hold.
Why Citrus Homes Are Different
Citrus is a small, unincorporated pocket of Los Angeles County tucked between Covina and Azusa, and the housing stock reflects its post-war boom years. Most homes were built between 1945 and 1975, which means a few things for ADU work. Foundation types vary from raised perimeter to slab-on-grade, sometimes on the same street. Sewer laterals on older Citrus properties often run closer to the surface than modern code assumes, so a detached ADU in the back half of a lot usually means a longer waste-line run than you’d see in a newer subdivision. Roof pitches on the original structures trend low, so tying a room addition into the existing roofline takes more structural planning than a simple gable-to-gable match.
Summer heat is the other driver. Citrus regularly sees stretches above 95°F in August, and uninsulated garages here become unusable by mid-morning. That’s why garage conversions in Citrus almost always include full wall and ceiling insulation plus mini-split sizing for a space that was never conditioned. We also see soil movement between wet and dry seasons, so we pay extra attention to drainage away from any new slab edge before we pour.
Our Main Citrus Services
Three services carry most of the calls we get from Citrus homeowners. Each has its own dedicated Citrus page with local pricing detail, and each one starts the same way: a written price before any work starts.
Home Addition Contractor in Citrus
Home additions in Citrus usually mean one of two things: pushing out at the rear of the house for a larger kitchen or family room, or converting an enclosed patio into conditioned square footage the assessor will actually count. Older Citrus lots often have side yards that look generous until you measure the required setback from the property line, so placement matters before anything gets drawn. We work through that math early, before you spend money on plans that won’t clear county review. Home Addition Contractor in Citrus covers project walks, foundation tie-ins, and what Citrus additions realistically cost.
ADU Builders in Citrus
Detached ADUs in Citrus have to fit within the rear-yard envelope while respecting setbacks on three sides, and on a 7,000-square-foot lot that typically means a 500 to 750-square-foot unit rather than the 1,200-square-foot maximum. We’ve built enough of these to know which lots handle a prep line kit like Dvele or Boxabl and which ones are better served by a stick-built design tailored to the exact yard shape. ADU Builders in Citrus walks through size limits, site prep, and the 365-Day Done Right Promise that applies to every ADU we complete.
Room Addition Contractor in Citrus
A room addition in Citrus is usually the most cost-effective way to add a home office, a ground-floor bedroom, or a larger laundry and mudroom without touching the roofline of the main house. The older post-war floor plans here tend to have one bathroom for three bedrooms, so a room addition often pairs with a bathroom build-out on the same permit. Room Addition Contractor in Citrus goes deeper on costs, estimated timelines, and what Citrus building officials tend to flag during plan check.

Costs in Citrus climb when the lot needs regrading, the sewer lateral has to be extended more than 30 feet, or the existing foundation needs bolting to meet current seismic codes. We hand you a written line-item price before any work starts, and that price doesn’t drift upward silently mid-project. If the scope changes, we put the change on paper, you sign it, and only then does the number move.
