Title 19

Division III — Project Design

Sonoma Zoning Code · 2026-06 edition · updated 2026-07-07 · Sonoma

This division provides standards and guidelines for the site layout and design of individual development projects within the various areas of the community. Because Sonoma is comprised of distinct areas with individual character and features representing different periods in history, the provisions of this division are organized by specific “planning areas” within the city. These standards and guidelines are intended to ensure that the appearance and function of proposed development preserves and enhances the desired character of each area.

The Sonoma Municipal Code is current through Ordinance 13-2025, passed December 3, 2025.
