What Happens When You Call

Step 1: You call (940) 242-3207. A live coordinator picks up and asks a few quick questions about your property: lot size, existing structures, and what you want the ADU to do for you. This takes about ten minutes and helps us understand whether a detached unit, garage conversion, or attached suite fits your situation.

Step 2: We schedule your on-site assessment. Our Houston team coordinates a time that works for you. You’ll know exactly who is coming before they arrive, because Threshold Standard means every technician’s name and photo are sent to you ahead of the visit. They’ll show a photo ID badge at the door, every time.

Step 3: You receive a written, line-item estimate. We put the price in writing before any work starts. That’s a Sutton ADU Builders rule from the Threshold Group family, and it applies in Houston just like everywhere else we operate. You’ll see every cost broken down so you can make a decision without surprises.

Step 4: We build it. Once you approve the estimate, permits are pulled, inspections are scheduled, and construction begins. You always know who is on your property, when they’re coming, and what they’re doing. The job wraps with a walkthrough and your Threshold Verified coverage in place.

Why Houston Homeowners Call Us First

  • You know exactly who is coming to your door. Every pro working under our name is required to hold the license and insurance their state requires. Before any visit, you get the technician’s name and photo. If anyone shows up who you were not told to expect, that visit is on us and we make it right.
  • Written pricing before any work begins. The Threshold Standard means no verbal estimates that change later. You get a written price, and that’s the price. No hidden fees, no change-order games, no surprises when the invoice arrives.
  • Local Houston team, established brand behind it. Sutton ADU Houston is an independently owned and operated branch of Sutton ADU Builders, part of the Threshold Group family. Miles Hartwell leads the local team, and the brand standards follow from a company with roots going back to 2006.
  • Built for Houston’s climate and codes. We know what Houston heat, humidity, and hurricane-season winds do to a structure. Our assessments account for drainage, foundation movement in clay soil, and the permit requirements specific to Harris County, Fort Bend County, and the surrounding areas.
