Serving clients throughout California, the studio provides professional architectural planning, drafting, permit processing, and 3D visualization services that help homeowners and developers transform ideas into construction-ready projects. With over 10 years of experience and more than 2,000 completed designs, Jean Prescott Studio has established itself as a trusted resource for permit-ready residential and commercial plans.

Unlike traditional design-build contractors, Jean Prescott Studio operates as an independent design firm, allowing clients to retain full ownership of their plans and obtain competitive bids from contractors of their choice. The firm manages every stage of the design process, including site planning, architectural drafting, permit documentation, plan corrections, and coordination with local jurisdictions, ensuring projects comply with California building and zoning requirements. Their services include custom ADUs, garage conversions, attached and detached ADUs, JADUs, home additions, and commercial developments.
