Regulations at a glance

Local rules & notes

Hillside Residential Combining District Restrictions: The city attempted to impose additional objective development and design standards from the Hillside District onto ADUs, which HCD identified as a violation of state law. Restrictive Car Share Definition: The city tried to limit parking exemptions by creating a narrow definition of 'car share' including fleet size and location requirements, which HCD ordered removed. Subjective Feasibility Criteria: The ordinance required a 'feasible alternative' finding for certain exceptions, which HCD ruled is too subjective for the required ministerial (over-the-counter) approval process.
