What Happens When You Call

Step 1: You call or request a callback. Our coordinator answers, listens to what you’re trying to build, and asks the questions that matter: lot size, setback concerns, existing structure, budget range. You’ll know before you hang up whether an ADU is realistic for your San Francisco property.

Step 2: We schedule your free assessment. We’ll find a time that works for you within our operating hours, Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. You’ll get a live arrival time, not a vague window. If anything changes, we update you.

Step 3: You receive a written estimate. After we walk your lot and understand the scope, we put every line item in writing before any work starts. That’s The Relay Standard: the price you see is the price you pay. No change orders hidden in the fine print.

Step 4: We build, and you watch it happen. The local San Francisco team handles the work under Troy Eastman’s direction. We send photo updates before, during, and after key milestones. You pay from a digital invoice link, not a paper chase.
