The city approved a new one-story, two-bedroom accessory dwelling unit of 891 square feet, plus a 142 square foot covered porch, in the side yard of a single-family home at 1801 S Vermont Ave. The city also recognized the home's existing attached carport, built in 1962, as a legal nonconforming structure because it extends into the street-side and rear setbacks.
