Reasons for Exemption
The project has been determined to be categorically exempt from the provisions of the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15301(e)(1), additions to existing structures provided that the addition will not result in an increase of more than 50 percent of the floor area of the structure(s) before the addition, or 2,500 square feet, whichever is less, of Title 14 of the California Code of Regulations. CEQA Guidelines Section 15301(e)(1) applies to the minor alteration of existing private structures, which the State has determined to be a class of projects that will not have a significant effect on the environment. The project involves the addition of a new attached garage with an accessory dwelling unit (ADU) below to an existing single-family residence located on a residentially zoned parcel, resulting in a 35 percent increase (976 square feet) in the floor area of the structure. Additionally, none of the exceptions set forth in CEQA Guidelines Section 15300.2, which would preclude a project from using a categorical exemption, are applicable.
Therefore, the project is exempt from CEQA pursuant to CEQA Guidelines Section 15061(b)(2) since the project meets the criteria for use of the existing facilities categorical exemption and the application of that categorical exemption is not barred by one of the exceptions set forth in Section 15300.2.
