About Us
Sun and Associates is based in Stockton, CA, and serves a wide region spanning from Sacramento to Modesto and throughout the Bay Area. We specialize in residential design services including Accessory Dwelling Units (ADUs), home expansions, and remodels. Our mission is to provide intelligent, code-compliant design solutions that help homeowners maximize the potential of their properties.
Our team is composed of experienced residential design professionals. While we are not licensed architects, we bring deep practical knowledge, attention to detail, and familiarity with local building codes to every project.
Our Story
Sun and Associates started with a simple goal — to make residential design more accessible, more responsive, and more practical for California homeowners.
Founded in Stockton, we’ve grown by working closely with clients who need thoughtful design without unnecessary complexity. Our background in drafting, permitting, and residential construction allows us to deliver clear, buildable plans that meet local codes and real-world budgets.
We’re not a large firm or a group of architects — we’re a small, focused team that understands what works and what matters in residential projects. From ADUs to additions, every project is an opportunity to help someone build something better.
