Accessory Dwelling Unit Changes Proposed
Posted on 12/19/2019

The Planning Commission and City Council will soon consider changes to bring the City's regulations regarding Accessory Dwelling Units into conformance with new state laws.

Following the Planning Commission's consideration of revised regulations and their recommendation that they be approved, on January 21, 2020, the City Council approved the first reading of an ordinance to amend Chapter 17 (Planning and Land Use) of the City Code to conform the City’s regulations regarding Accessory Dwelling Units to new state laws. The City Council will hold a public hearing to adopt the proposed ordinance on February 3, 2020.

On February 10, 2020, the Planning Commission will consider amendments to the Piedmont Design Guidelines to establish objective architectural and landscape standards for ADUs, also in conformance with the new state laws. The City Council is tentatively scheduled to review the proposed amendments to the Piedmont Design Guidelines at a public hearing on Tuesday, February 18, 2020. 


On January 1, 2020, new state laws come into effect which limit a local jurisdiction’s ability to regulate Accessory Dwelling Units (ADUs). The provisions affected by the changes to state law include, but are not limited to: ministerial review of all ADU permit applications, off-street parking requirements, unit size limitations, application approval timelines, owner occupancy, and the allowance for junior accessory dwelling units (JADUs), ADUs on multi-family properties and ADUs that must be approved by-right. Local laws which do not conform to these new state standards are preempted and cannot be enforced. City staff has developed the proposed ordinance which will be considered by the Planning Commission and the City Council to conform Piedmont’s ADU regulations to the new state law.
