What Happens When You Call

We keep the process simple and transparent from the first conversation to the final walkthrough. Here’s what to expect when you reach out to Seedling ADU Builders.

  • You call (707) 383-5338. A live coordinator picks up, asks which city you’re in, and routes you to the local team that covers your address. You won’t get bounced between departments.
  • We schedule a property assessment. We’ll pick a time that fits your schedule. Our team walks the site, looks at setbacks, utility access, and how the unit will fit with your existing home.
  • You receive a written estimate. Before any work starts, you get a written line-item price. No verbal ballparks that change later. You’ll know exactly what’s included and what isn’t.
  • We build your ADU. Once you approve the price, construction begins. Every job follows the Cedarwell Care Promise: shoe covers and drop cloths inside the house, quiet tools when the kids are asleep, pet-safe products where there’s a choice, and a photo of the clean-up before we leave.

The whole process is built so you always know where things stand. Written prices, clear timelines, and a team that treats your home like a home.

Why Los Angeles Homeowners Call Us First

  • Written price before any work starts. No change orders that surprise you mid-project. The estimate you approve is the price you pay, and any adjustment gets discussed before it happens.
  • License and insurance required at every location. Every pro working under our name is required to hold the license and insurance their state requires. That’s a network standard, not a suggestion.
  • The Cedarwell Care Promise on every job. We protect your floors with shoe covers and drop cloths, explain the price before the work, and leave the house clean. Ask before we move or touch anything. That’s the C.A.R.E. code: Clean up like it’s our own home, Ask first, Respect quiet hours, Explain the price.
  • Led by Ben Ortega. Seedling ADU Builders is led by Ben Ortega, who holds every location to the same standard of care and clarity. When a job doesn’t feel right, it gets fixed before it’s called done.

We build ADUs for families with kids and pets. That means clean floors, safe products, clean air, and a crew that treats your house the way you do.
