- A sample ADU review contrasts a window’s roughly 3.5-square-foot clear opening with a stated 5.7-square-foot requirement.
Field notes
The six-step walkthrough includes a sample ADU review on sheet A2.1, with separate comments for an escape window and dwelling-unit separation. One comment specifies a 5.7-square-foot net opening and a sill no higher than 44 inches; another calls for a one-hour separation extending to the roof sheathing. The page also describes separate city queues and reviewer permissions, with administrators able to search across files.
