In the heart of the SGV. Come in and ask your questions face to face — we'd rather you meet us before you decide anything.

Make the first call count

What to have ready (none of it is required)

You don't need drawings, a budget, or any paperwork to talk to us — plenty of families call with nothing but an idea. But if you want the most useful first conversation, these help:

  • The property address (so we can look at the lot and city rules)
  • What you're hoping to build — ADU, new home, or not sure yet
  • Who it's for: family members, rental income, or both
  • A rough sense of timing — this year, next year, just exploring
  • Your questions — especially the uncomfortable ones about cost and time

What happens after you reach out

We'll talk through your property and goals, usually followed by a free evaluation of what your lot allows. If the project makes sense, we'll explain the four phases as they'd apply to you — including honest cost ranges and city timelines. If it doesn't make sense, we'll tell you that too.

Before deciding anything, feel free to verify our license and insurance — we encourage it.
