  • Prepare your site plan. The site plan should show all development on the parcel including the propose location of the new structure and any supporting utility. Please refer to the plan submittal checklist for more details.
  • Verify your property setbacks or restrictions are in compliance. Please contact the Planning Department to discuss your proposed building site and to obtain your property setbacks.
  • Consider if you need to grade your parcel for the addition of the new structure. If so, you will need to submit grading plans as part of your plan submittal.
  • Look into development standards for accessory or second dwelling units. They can be found on the ADU FAQ handout.

For a complete plan submittal, please ensure you include the following:

  • Site plan

Design Philosophy

Each ADU has been designed to be adaptable to various locations, styles, and budgets, providing homeowners with a customizable living space that suits their unique needs and preferences. All plans can be utilized as either a slab or raised floor, providing versatility to accommodate different foundation options. The designs were created to enable owners to modify the facade and elements, so they can reflect the surrounding environment, aesthetic preferences, and existing structures.

Additionally, the designs are created to be as cost-effective as possible, utilizing space efficiently without sacrificing comfort and functionality. The open-concept living areas provide a welcoming atmosphere, while the separate bedroom zones offer privacy. The inclusion of features such as covered outdoor spaces and optional garages further enhance the flexibility of the designs.
