    We require a 4’ wide pathway that connects the door of the ADU to the adjacent street. The pathway must be an improved surface (concrete, asphalt, etc.) and can connect to the driveway. Please update your site plan to show this pathway before submitting your final application.I also noticed that the square footage of the garage and ADU is different on your site plan than your project description. Please make sure those match before submitting.
