At Build By Design, we bring something unique to property development: decades of experience working inside  planning departments. We’ve reviewed thousands of applications, collaborated with city officials, and seen exactly where property owners get stuck.

Now we use that insider knowledge to help you succeed. We assess your property’s SB9 potential, design projects that meet city requirements the first time, and guide you through permitting with confidence. Whether you’re considering a lot split, ADU, or duplex development, we translate complex regulations into clear action steps.

From feasibility to final approval, we handle the planning strategy while you focus on your goals—whether that’s housing for family, generating rental income, or maximizing property value. SB9 opens incredible opportunities. We make sure you actually get to use them.
