About Otto & Sons Construction

Family-owned general contracting built on legacy, trust, and a commitment to doing the work right.

Alani Tangitau — Owner & Founder

Our Story

Built on a Father’s Legacy

Otto & Sons Construction started the way most great things do — with one man, a pickup truck, and a refusal to cut corners. Alani’s father built the foundation of this company through grit, hard work, and a standard that never wavered. Today, Alani is carrying that legacy forward, growing the family business and bringing those same values to every single job.

We’re not a big company, and we’re proud of that. You won’t pay for five people to get one job done. When you hire us, you get direct access to the person actually building your project — someone who communicates clearly, shows up when they say they will, and treats your home or business like it matters. Because it does.

As a licensed general building contractor (CA License #1104751), we handle everything from initial consultation and permitting to final walkthrough. Based in Antioch, California, we serve homeowners and businesses throughout the East Bay — and our reputation has always grown the old-fashioned way: one satisfied client at a time.

Every project gets the same attention to detail, whether it’s a fence repair or a full commercial buildout.
