What Happens When You Call

We keep the process simple because adding an ADU in Fountain Valley already involves enough moving parts. Here’s exactly what to expect from your first call to the final walkthrough.

Step 1: You call (866) 403-9834. A live coordinator answers during business hours and asks a few quick questions about your property. We want to know the basics: lot size, existing structures, and what you’re imagining for the ADU.

Step 2: We schedule your free assessment. A member of our team visits your Fountain Valley property, walks the site with you, and checks things like setback requirements, utility access, and garage or backyard conditions. We’ll give you honest feedback about what’s feasible before any money changes hands.

Step 3: You receive a written estimate. Within a few days of the assessment, you’ll get a line-item quote covering construction, materials, permits, and any site work. Our pricing is transparent, and what we quote is what you pay unless you ask us to change the scope.

Step 4: We build your ADU. Once you approve the estimate and permits are pulled, construction begins. We handle the inspections and keep you updated throughout. When we’re done, you do a final walkthrough and receive your workmanship warranty details.

Why Fountain Valley Homeowners Call Us First

  • Local familiarity with Fountain Valley zoning. Fountain Valley’s ADU requirements differ from what you’ll find in Huntington Beach or Garden Grove, and we know the city’s setback, height, and parking standards. That local knowledge prevents costly surprises during plan review.
  • Real hours that work for working people. You can reach us Monday through Friday from 7:00 AM to 7:00 PM, and Sundays from 7:00 AM to 7:00 PM. Our coordinators answer during those published hours, so you’re not leaving messages into a void.
  • Transparent, line-item pricing. Every estimate we write is itemized so you see exactly where your money goes. No hidden fees, no vague “miscellaneous” charges, and no change orders unless you initiate a scope change.
  • Standing behind the work. Every pro who works under the Home Base ADU Builders name is required to hold the license and insurance their state mandates. The written estimate is free, and the workmanship comes with a warranty we explain in plain language before you sign anything.
