Summary
Petaluma zones farmland separately: the AG (Agriculture) zone under Section 4.020(B) covers land actively and primarily used for grazing or producing food and fiber for sale, including FEMA flood-hazard parcels. Table 4.1 lists crop production and farm animal keeping as permitted, by-right uses in the AG, OSP, RR and R1 zones, with no conditional use permit required.
B. AG (Agriculture) Zone. The AG zone is applied to areas that are actively and primarily used for grazing, or the production for sale of food and fiber. Areas subject to seasonal or historic flooding and identified by FEMA as areas warranting special consideration are included. The AG zone is consistent with and implements the agriculture land use classification of the general plan. ... | LAND USE TYPE (1) | Permit Required by Zone | Specific Use |

Full Breakdown
' The AG zone implements the agriculture land use classification of the city's general plan, distinct from the Rural Residential, Residential 1-5 and commercial zones that surround Petaluma's built-up core. 5 set out every allowed land use citywide and the planning permit each requires. 1, covering the Natural and Rural Zones (OSP, AG, RR and R1), marks 'Crop Production, Horticulture, Orchard, Vineyard' and 'Farm Animal Keeping' with a 'P,' meaning Permitted Use, in all four zones, so no conditional use permit, hearing or discretionary review is needed to grow crops or keep farm animals there.
Where a specific use carries a section number in the 'Specific Use Regulations' column, that section can impose additional standards; the agricultural rows carry none, so no extra permit layer attaches. This is a zoning designation that keeps farming a matter of right in the AG zone, not a separate nuisance-immunity right-to-farm ordinance: Petaluma's code contains no standalone provision shielding an agricultural operation from a neighbor's nuisance complaint, so anyone relying on broader right-to-farm protection should confirm current law with the Planning Division or a land use attorney before assuming immunity beyond the by-right zoning itself.
Violations & Fines
The Zoning Administrator and Building Official enforce the Zoning Ordinance under Section 26.010, and Section 26.020(A) declares any land use maintained contrary to the ordinance, such as converting AG-zoned land to a use outside Table 4.1 without the required permit, 'unlawful and a public nuisance,' authorizing the City Attorney to seek abatement, injunction and removal through the courts on the City Council's order.
