What Happens When You Call

Here’s the process from first call to finished ADU, step by step. We keep it simple because the decision to build on your lot is already a big one.

Step 1: You Call (661) 430-0429

A live coordinator answers during business hours. You’ll tell us what you’re thinking about: a detached unit for aging parents, a rental for income, or extra space for grown kids. We listen first, then ask a few questions about your lot and your timeline.

Step 2: We Schedule Your Free On-Site Assessment

Miles Hartwell or a member of the local team comes out to walk your Santa Clarita property. We look at setbacks, access, utility connections, and any site conditions that affect the build. You get honest feedback about what’s feasible and what’s not.

Step 3: You Receive a Written, Line-Item Estimate

Every job gets a written price before any work starts. That’s the Threshold Standard, and it applies to every Sutton ADU location. You’ll see exactly what’s included: plans, permits, site work, construction, and finishes. No vague allowances, no surprises later.

Step 4: We Build, You Watch It Happen

When you approve the estimate, we schedule the work and keep you updated throughout. Every technician who comes to your door is background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. If anyone arrives who you weren’t told to expect, that visit is on us and we make it right.

Why Santa Clarita Homeowners Call Us First

  • Local team that knows Santa Clarita lots. Building an ADU in Valencia is different from building one in Canyon Country. Hillside setbacks, HOA rules, and the city’s specific ADU ordinance all affect your project. Miles Hartwell and our local team deal with these every week, so you don’t have to learn them from scratch.
  • Written pricing before any work starts. You’ll never get a verbal estimate followed by a surprise invoice. The Threshold Standard means every job gets a written price first. If the scope changes, you approve the change in writing before we proceed.
  • You know who’s coming before they arrive. Before every visit, we send the technician’s name and photo. At the door, they show a photo ID badge and arrive in a clean, marked uniform. That matters if you’re home alone, have young kids, or just want to feel certain about who’s on your property.
  • Covered by Threshold Verified. Every Sutton ADU project is backed by the Threshold Group guarantee. The technicians we send are background-checked and identity-verified as a requirement, not a perk. It’s the same standard across the Threshold family of brands, and it applies to every job we do in Santa Clarita.
