The Full-Process ADU Specialists

Most contractors hand you off between designers, permit runners, and builders. Not us. Peninsula Construction handles everything — from initial design concepts to permits to the final walkthrough. One team, one point of contact, one price.

As real estate investors ourselves with 12+ years of experience, we understand what makes an ADU a smart investment — not just a nice addition.
