Professional Support | 3D Plans

Our designer captures precise measurements of your home and transforms them into detailed, full-color 3D renderings, plans, and elevations. Before any construction begins, you'll have the opportunity to take a virtual tour of the design. We’ll provide a comprehensive proposal, including an itemized breakdown, clear payment schedule, and project terms, all outlined in the Project Specification Sheet. Your feedback is encouraged throughout the process, and we’ll collaborate closely to bring your vision to life. Once the design is approved and the contract signed, we’ll proceed with securing the permit.

ADU Permit

Master the Permitting Process

The permitting process for accessory dwelling units can be challenging, but with Fortune ADU Design Build’s extensive experience in California, we are well-versed in navigating each jurisdiction’s requirements. We conduct thorough property research before the design phase to ensure your project is feasible. Our Research & Development team stays up-to-date with State, County, and city regulations to ensure a smooth permitting experience. We manage the submission of all documents and closely track the process until your permit is approved.
