4.010 Purpose. ¶

This chapter lists the land uses that may be allowed by Section 2.020 (Zoning Map and Zones), determines the type of planning permit approval required for each use, and provides basic standards for site layout and building size. (Ord. 2764 § 3 (Exh. A), 2021.)

4.020 Purpose of Established Zones. ¶

A. OSP (Open Space and Park) Zone. The OSP zone is applied to undeveloped areas and sites that are appropriate for the preservation of natural resources, outdoor recreation, to be maintained in open space for the protection of public health and safety, and existing city public parks. City parks located in this zone may include buildings, structures, and uses that serve the community (e.g., Luchessi Community Center, Novak Center, Cavanaugh Center, library, water resources building, etc.). The OSP zone is consistent with and implements the urban separator, open space, and city park land use classifications of the general plan.

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.

C. RR (Rural Residential) Zone. The RR zone is applied to areas of single dwelling development with a minimum lot size of two acres. This zone would be applied primarily to areas at the western perimeter of the city along the urban growth boundary that are developed with single dwellings at densities ranging from 0.1 to 0.6 units per acre. This zone is intended to maintain a rural character and provide a transition to unincorporated rural and agricultural lands. The RR zone is consistent with and implements the rural residential land use classification of the general plan.

The Petaluma Implementing Zoning Ordinance is current through Ordinance 2907, passed September 8, 2025.

D. R1 (Residential 1) Zone. The R1 zone is applied to areas of single dwelling development, primarily the western hillsides, with densities ranging from 0.6 to 2.5 units per acre, and larger lots required for sloped sites. The R1 zone is consistent with and implements the very low density residential land use classification of the general plan.

E. R2 (Residential 2) Zone. The R2 zone is applied to areas previously developed and intended for detached single dwellings on individual lots, at densities ranging from 2.6 to 8.0 units per acre. The R2 zone is consistent with and implements the low density residential land use classification of the general plan.

F. R3 (Residential 3) Zone. The R3 zone is applied to the older neighborhoods surrounding the downtown that are characterized by a variety of housing types and densities in a walkable context. Densities range from 6.1 to 12.0 units per acre. The R3 zone is consistent with and implements the diverse low density residential land use classification of the general plan.

G. R4 (Residential 4) Zone. The R4 zone is applied to areas intended for a variety of housing types ranging from single dwellings to multi-unit structures. Densities range from 8.1 to 18.0 units per acre. The R4 zone is consistent with and implements the medium density residential land use classifications of the general plan.

H. R5 (Residential 5) Zone. The R5 zone is applied to areas intended for the most urban housing types at densities ranging from 18.1 to 30.0 units per acre, but where existing lower density housing is considered conforming. The R5 zone is consistent with and implements the high density residential land use classification of the general plan.

I. MH (Mobile Home) Zone. The MH zone is applied to existing mobile home parks throughout the city. The MH zone is consistent with the mobile home land use classification of the general plan.

J. C1 (Commercial 1) Zone. The C1 zone is applied to existing smaller-scale shopping centers with off-street parking, or clusters of street-front stores that serve the surrounding neighborhood. The C1 zone is consistent with and implements the neighborhood commercial land use classification of the general plan, which establishes a maximum floor area ratio of 0.8 for the classification.

K. C2 (Commercial 2) Zone. The C2 zone is applied to existing community and regional shopping center sites. The C2 district is consistent with and implements the community commercial land use classification of the general plan, which establishes a maximum floor area ratio of 1.2 for the classification.

L. MU1A, MU1B, MU1C (Mixed Use 1) Zone. The MU1 zone is applied to areas intended for pedestrian-oriented, mixed-use development with ground-floor retail or office uses adjacent to the downtown core, and in other areas of the city where existing auto-oriented commercial areas are intended for improvement into pedestrian-oriented mixed use development. The MU1 zone is consistent with and implements the mixed use land use classification of the general plan, which establishes a maximum floor area ratio of 2.5 for both residential and nonresidential uses within the classification, and a maximum density of 30 units per acre for residential.

Note:

■ Mixed Use 1A Zone This zone is applied to parcels located along corridors such as East Washington Street, Petaluma Boulevard North, Bodega Avenue and Lakeville Street. The parcels in these zones vary in size and are typically located adjacent to residential zones.

The Petaluma Implementing Zoning Ordinance is current through Ordinance 2907, passed September 8, 2025.

Page 3 of 38

Ch. 4 Zone Districts and Allowable Land Uses | Petaluma Implementing Zoning Ordinance

Mixed Use 1B Zone This zone is applied to larger parcels located primarily along major arterial roadways.
The larger parcel size should allow for a mix of uses on the site.
Mixed Use 1C Zone This zone is applied to smaller parcels located in West Petaluma. Most of these parcels
are located in residential areas and the intensity of the uses permitted in this zone is limited.

M. MU2 (Mixed Use 2) Zone. The MU2 zone is applied to the Petaluma downtown and adjacent areas that are intended to evolve into the same physical form and character of development as that in the historic downtown area. The MU2 zone is consistent with and implements the mixed use land use classification of the general plan, which establishes a maximum floor area ratio of 2.5 for both residential and nonresidential uses within the classification, and a maximum density of 30 units per acre for residential.

N. BP (Business Park) Zone. The BP zone is intended for business and professional offices, technology park clusters, research and development, light industrial operations, and visitor service establishments, with retail as a secondary use only. The BP zone is consistent with and implements the business park land use classification of the general plan, which establishes a maximum floor area ratio of 1.5 for the classification, although an FAR of 3.0 is allowed if all required parking is structured.

O. I (Industrial) Zone. The I zone is applied to areas that are appropriate for a full range of manufacturing, industrial processing, general service, warehousing, storage and distribution operations. Small restaurants and service commercial are allowed as ancillary uses. The I zone is consistent with and implements the industrial land use classification of the general plan, which establishes a maximum floor area ratio of 0.6 for the classification.

P. CF (Civic Facility) District. The CF zone is applied to sites for proposed public utility facilities, government offices, community service uses and lands, and significant sites owned and operated by the elementary, secondary, or community college districts, as well as private and/or parochial schools. The zone implements and is consistent with the public/semi-public, and education classifications of the general plan.

Q. FW (Floodway) Zone. The FW zone is applied to sites within the boundaries of the “Areas of Special Flood Hazard” and identified as “Floodway” areas. See Chapter 6 for the requirements of the floodway zone.

R. Planned Unit Districts and Planned Community Districts. The historic use of P.U.D.s and P.C.D.s for the development of residential, industrial, and commercial properties in various zones in which the underlying P.U.D. and/or P.C.D. uses are permitted is hereby recognized. Nonresidential P.C.D.s in existence as of May 19, 2008, and residential P.U.D.s are recognized to be consistent with the intent of these regulations by the establishment of their individual and respective P.U.D. and P.C.D. standards. Development and redevelopment of lands within P.U.D.s and P.C.D.s, including modification of P.C.D.s and/or addition of land to P.C.D.s, shall be in accordance with the individual adopted standards for said P.U.D. or P.C.D. and other applicable zoning standards not otherwise modified by the P.U.D. or P.C.D. adopted standards. The creation and modification of P.U.D.s, and the modification and/or addition of land to P.C.D.s existing as of May 19, 2008, is regulated by Chapter 19 herein. The creation of wholly new P.C.D.s, or the addition of land to a P.C.D. where the expansion area is not immediately adjacent, is not permitted by this chapter. (Ord. 2764 § 3 (Exh. A), 2021.)

The Petaluma Implementing Zoning Ordinance is current through Ordinance 2907, passed September 8, 2025.

Ch. 4 Zone Districts and Allowable Land Uses | Petaluma Implementing Zoning Ordinance

4.030 Allowable Land Uses and Permit Requirements. ¶

A. General Permit Requirements. Tables 4.1 through 4.5 identify the land uses allowed by this Zoning Ordinance in each zone, and the planning permit required to establish each use, in compliance with Section 3.030 (Allowable Land Uses and Planning Permit Requirements).

B. Requirements for Certain Specific Land Uses. Where the last column in Tables 4.1 through 4.5 (“Specific Use Regulations”) includes a section number, the referenced section may affect whether the use requires a conditional use permit, and/or may establish other requirements and standards applicable to the use. (Ord. 2764 § 3 (Exh. A), 2021.)

4.040 Site Planning and Building Standards. ¶

Subdivisions, new land uses and structures, and alterations to existing land uses and structures, shall be designed, constructed, and established in compliance with the requirements in Tables 4.6 through 4.13, in addition to the applicable standards (e.g., landscaping, parking and loading, etc.) in Chapters 11, 13, and 14. (Ord. 2764 § 3 (Exh. A), 2021.)

4.050 Dedication Required and Exceptions. ¶

A. Dedication Required. The developer shall dedicate any necessary right-of-way to the city to the alignment established by plan lines established in Chapter 13.20 of the Petaluma Municipal Code, or to an alignment consistent with applicable city right-of-way standards across the entire frontage or frontages and shall construct public improvements (including but not limited to curbs, gutters, sidewalk, half street, water mains, storm drains and sanitary sewers) across such frontage to current city standards, whenever a development project is located, or which is proposed to be located:

Upon one or more streets or roads where future right-of-way plan lines have been established pursuant to Chapter 13.20 of the Petaluma Municipal Code; or
Upon one or more streets or roads which are not improved with existing curbs, gutters, sidewalks and other contiguous street improvements across the frontage or frontages of the property upon which said development project is located; or
Upon a parcel of real property which has frontage on a dedicated street right-of-way where no such improvements have been constructed contiguous to the parcel upon which the development project is located. Nothing in this section shall be construed to prevent the city from requiring construction of frontage improvements pursuant to any other ordinance or regulation of the city.

B. Exceptions. Subsection (A) of this section shall not apply when any one or more of the following conditions exist:

The Petaluma Implementing Zoning Ordinance is current through Ordinance 2907, passed September 8, 2025.

Page 5 of 38

Ch. 4 Zone Districts and Allowable Land Uses | Petaluma Implementing Zoning Ordinance

Where a condition of any subdivision or parcel map requires dedication and construction or public improvements as a condition of approval of the same development project.
Where the value of the construction is less than $10,000. This valuation may be raised by resolution of the city council to compensate for inflation and increased building costs.
Where the proposed development project is clearly accessory, as determined by standards in the Zoning Ordinance, to an existing use upon the property.
Where the development project consists primarily of the rehabilitation of an existing structure, when no change of use will occur.
Where the developer establishes that the required dedication would render the real property upon which the development project is to be constructed substantially valueless for any private use, but final determination of such fact shall be made only by the city council upon petition of the developer or owner. (Ord. 2764 § 3 (Exh. A), 2021.)
