Title: Zoning Ordinance Amendment Regarding Accessory Dwelling Unit Regulation Updates - Citywide. A proposed amendment to the Alameda Municipal Code to revise sections relating to the Accessory Dwelling Unit (ADU) ordinance in Alameda Municipal Code Sections 30-5.18 Accessory Dwelling Units to update references to state law, to authorize the conversion of ADUs into condominiums, to establish standards and processes for such conversions, to clarify the development standards applied to ADUs, and to reformat the sections of the ordinance for ease of use. The proposal is exempt from the California Environmental Quality Act (CEQA) pursuant to Public Resource Code section 21080.17 which exempts ordinances implementing State ADU law and CEQA Guidelines Section 15061(b)(3), the common sense exemption where it can be seen with certainty that the proposed zoning text amendment has no possibility of having a significant effect on the environment.
