What Happens When You Call

Step 1: You call (858) 988-6447. A coordinator answers and asks a few simple questions: your San Diego neighborhood, your lot size, and what you’re picturing for the ADU. The goal is to see if an accessory dwelling unit even makes sense on your property before anyone drives out.

Step 2: We schedule your on-site assessment. Ben Ortega or a member of his team visits your San Diego property at a time that works for you. They walk the lot, check setbacks and utility access, and talk through what’s realistic for your space and your budget.

Step 3: You get a written price. No verbal ballparks that shift later. Every job gets a written line-item estimate before any work starts, so you know exactly what you’re paying and why. The price you see is the price we stand behind.

Step 4: We build it. Once you approve the estimate and permits are in hand, construction begins. The crew follows the Cedarwell Care Promise on every visit: shoe covers inside the house, quiet tools during nap hours, pet-safe products where there’s a choice, and a photo of the clean-up before we leave.

Why San Diego Homeowners Call Us First

  • Local team, local knowledge. Ben Ortega leads Seedling ADU San Diego and knows how this city’s parcel shapes, coastal setbacks, and hillside lots affect ADU design. You’re not getting a generic playbook from another market; you’re getting someone who understands what builds well in San Diego.
  • Licensed and insured the right way. Every pro working under the Seedling name is required to hold the license and insurance their state requires. We don’t take shortcuts on credentials, and we don’t expect you to either.
  • Written pricing before work starts. We give you the price range in dollars on the page when you request an estimate. No hidden fees, no surprise change orders, no “it turns out we need more” conversations halfway through the job.
  • The Cedarwell Care Promise on every project. Clean up like it’s our own home. Ask before we move or touch anything. Respect your family’s time and quiet hours. Explain the price before the work. That’s the standard Seedling ADU San Diego works to on every build.
