Contact Seedling ADU Pasadena – Free ADU Estimate in Pasadena

Ready to talk about your ADU? Call us at (626) 657-5461 and you’ll reach a live coordinator who connects you with our Pasadena team, not a script. The call is a conversation, not a sales pitch. We’ll listen to what you’re picturing, ask a few questions about your lot, and set up a free on-site assessment at a time that works for you. You’ll know exactly what happens next before you hang up.

What Happens When You Call

Step 1: You call, we answer. A live coordinator picks up during business hours, Monday through Friday 7am to 7pm and Sunday 7am to 7pm. You’ll describe what you’re thinking about, whether that’s a detached backyard unit, a garage conversion, or something you haven’t fully worked out yet.

Step 2: We schedule your free assessment. We come out to your Pasadena property, walk the lot with you, check setbacks, access, and utility locations, and take measurements. You’ll meet the local team that would actually build your ADU, and Ben Ortega oversees the process from first visit to final walkthrough.

Step 3: You get a written estimate. No verbal ballparks and no surprises later. We put the full scope and price in writing before any work starts, which is the same standard every Seedling ADU Builders location follows. If anything in the estimate needs adjusting as the design evolves, we explain it in writing first.

Step 4: We build it, carefully. Construction crews follow the same care rules on every job: 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. When the job is done, you’ll have a new home on your lot, built with care.

Why Pasadena Homeowners Call Us First

  • Local Pasadena team, not a distant dispatch. Our crew works in Pasadena, East Pasadena, Glendale, Alhambra, and the surrounding foothill neighborhoods every week. We know the city’s setback rules, the hillside lot challenges in Sierra Madre and Tujunga, and how the San Gabriel Valley sun and soil affect foundation choices.
  • Required licensing and insurance, always. Every pro working under the Seedling ADU Builders name is required to hold the license and insurance their state requires, and we carry the coverage a construction project in California demands. We’re glad to provide documentation with your written estimate.
  • Written price before any work starts. Our promise is simple: no hidden fees, no mid-project change orders nobody warned you about. The estimate you receive is the number you plan around, and if something genuinely changes, we explain it in writing and get your sign-off before proceeding.
  • The Cedarwell Care Promise, on every job. Shoe covers and drop cloths inside the house, quiet tools when the kids are asleep, pet-safe products where there’s a choice, a photo of the clean-up before we leave, and a written price before any work starts. That’s the standard, not the exception.

Our Service Area Around Pasadena

We regularly build ADUs throughout Pasadena and the surrounding San Gabriel Valley. Here’s where our crews spend most of their time:
