Contact Orange ADU Builders – Free ADU Estimate in Orange

Call us at (877) 265-5812 for a free ADU estimate in Orange. When you call, you’ll reach a live coordinator who asks a few questions about your property and goals, then connects you with our local team. No hard sell, no pressure. We simply figure out whether an ADU makes sense for your lot, and if it does, we lay out the next steps clearly. Most callers get their initial assessment scheduled the same week.

What Happens When You Call

Step 1: You call (877) 265-5812. A live coordinator answers and listens. Tell us the basics: your address in Orange, lot size, and what you’re imagining for the ADU. We’ll ask about your goals, whether it’s rental income, housing for family, or adding resale value. This call takes about ten minutes.

Step 2: We schedule a property assessment. A member of our Orange team visits your home to look at setbacks, access, utility connections, and grading. We walk the space with you and talk through what’s realistic for your specific lot. You get honest feedback about what will work and what won’t, before any money changes hands.

Step 3: You receive a written line-item estimate. Within a few days of the assessment, we send a clear breakdown of costs: design, permits, site work, construction, and finishes. The number on the page is the number we build to. No vague allowances, no surprise change orders down the road.

Step 4: Permits, construction, and completion. Once you approve the estimate, we pull permits from the City of Orange and schedule the work. Our team manages inspections and keeps you updated through every phase. When we hand over the keys, the ADU is move-in ready.

Why Orange Homeowners Call Us First

  • Response time that respects your schedule. Our team is based in Southern California and serves Orange directly. You won’t wait weeks for a callback. We answer during business hours, Monday through Friday from 7 AM to 7 PM, and Sunday from 7 AM to 7 PM.
  • Licensed and insured, required at every level. Every pro working under our name is required to hold the license and insurance their state requires for ADU construction. You get a written estimate from a company that stands behind the people doing the work.
  • Transparent pricing with no hidden fees. The estimate you approve is the price you pay. We don’t bury line items in vague categories like “miscellaneous” or tack on change orders when the project is underway. If something changes, you know before it happens and approve it in writing.
  • Workmanship guarantee on every build. We’ve been building ADUs since 2013 and our workmanship warranty is part of every contract. If something isn’t right after completion, we come back and make it right. That’s been our standard for over a decade in Orange and the surrounding communities.
