Legal Question in Real Estate Law in California

I believe each county can determine by ordinance,perhaps even by policy, within reason, what constitutes a "major variance." Once the distinction is set up, it can have fairly significant consequences for how the variance approval process may be conducted. I think minor variances are considered "ministerial" and thus can be processed by a clerk upon presentation of properly filled-out application papers. On the other hand, a major variance is discretionary, not ministerial, in nature, and the application must be reviewed for consistency with other laws, ordinances and policies, and one or more decision-makers must form an opinion as to the lawfulness or appropriateness of the proposed variance.
