What Happens When You Call

Step 1: You call (855) 676-6807. A live coordinator answers during business hours. They’ll ask a few quick questions about your Highland property: lot size, existing structures, and what you’re hoping to build. The goal is to understand, not to pitch.

Step 2: We schedule your free on-site assessment. A member of our local team visits your property in Highland, walks the site with you, and checks setbacks, access, and utility locations. You’ll get honest feedback about what’s feasible before anyone talks numbers.

Step 3: You receive a written line-item estimate. We put everything on paper: design, permits, materials, labor, and a clear project timeline. The number you see is the number we work from. If something changes, we tell you before it changes.

Step 4: We build, you stay informed. Permits get pulled, inspections get scheduled, and work gets completed according to the agreed scope. You’ll know what’s happening at every stage, from foundation to final walkthrough.

Why Highland Homeowners Call Us First

  • Free, no-obligation assessments in Highland. We come out, look at your property, and tell you what’s actually possible. You don’t pay for the visit, and you’re never locked into anything by accepting it.
  • Licensed and insured, with transparent requirements for every pro. Every professional working under our name is required to hold the license and insurance their state requires. We’re insured and bonded, and we’re happy to verify credentials before any work begins.
  • Written line-item pricing with no hidden fees. You’ll see exactly where your money goes: design, permits, site preparation, construction, finishes. No vague “miscellaneous” line items. No surprise change orders dropped on you mid-project.
  • Workmanship warranty on completed ADUs. We stand behind the work we do in Highland, San Bernardino, Redlands, and the surrounding areas. If something isn’t right after we finish, we make it right.

Our Service Area Around Highland

We serve Highland and the surrounding Inland Empire communities, including San Bernardino, Redlands, Mentone, Loma Linda, Colton, Grand Terrace, and Rialto. We also take on projects in the San Bernardino mountain communities of Running Springs, Lake Arrowhead, Crestline, and Muscoy. Each area has its own terrain, setback rules, and utility considerations, and we factor those in from the first conversation. If you’re outside the cities listed above, call us anyway. Your project may still fall within our service area.
