Setbacks determine how close the ADU can be built to property lines, existing structures, other buildings on the property, and public rights-of-way to help maintain adequate spacing and accessibility.
San Diego requires one off-street parking space for ADUs. However, there are some exceptions and variations to this requirement based on factors such as proximity to public transit, the size of the ADU, or if the ADU is within a historic district.
Consider designing the ADU to complement the architectural style of the existing primary dwelling and the neighborhood to maintain visual harmony.
Your 2-story ADU should be designed to provide safe and accessible features such as clear pathways, proper lighting, and handrails on stairs.
Maximize natural light and ventilation in the ADU by incorporating large windows, skylights, and well-placed openings.
Incorporate sustainable design features into your ADU, such as energy-efficient appliances, insulation, solar panels, and water-saving fixtures, to minimize environmental impact and reduce operating costs.
