§ 9-500

San Joaquin County Zoning Code · 2026-06 edition · updated 2026-07-25 · San Joaquin County

9-500.010 - TITLE, CITATION, AUTHORITY, AND INCORPORATION BY REFERENCE

The 500 Series shall be known and cited as the "Subdivision Ordinance of San Joaquin County," the "Subdivision Ordinance," or the "Subdivision Regulations." The Subdivision Map Act (Title 7, Division 2, of the California Government Code, as amended) is hereby adopted by reference and made a part of this

Ordinance as though it was fully set forth herein. The provisions of this Ordinance are supplemental to the Subdivision Map Act.

9-500.020 - PURPOSE

The purpose of the Subdivision Regulations is to regulate and control the division of land within San Joaquin County. These provisions implement and supplement the requirements of the Subdivision Map Act concerning the design, improvement and survey data of subdivisions, the form and content of all maps provided for by the Subdivision Map Act and the procedure to be followed in securing the official approval of the Zoning Administrator, Planning Commission, Director of Public Works, County Surveyor, and Board of Supervisors regarding the maps.

To accomplish this purpose, these regulations are determined to be necessary for the preservation of the public health, safety, and general welfare, to promote orderly growth and development and to promote open space, conservation, protection, and proper use of land, and to ensure provision for adequate traffic circulation, utilities, and services. It is also the purpose of this Ordinance to ensure that the design and improvement of subdivisions is consistent with and promotes the goals and policies of the General Plan and any applicable Specific Plan, pre-existing Special Purpose Plan, or Master Plan. More specifically, these regulations are intended to:

(a)

Establish reasonable standards of design and reasonable procedures for subdivision and re-subdivision for the orderly layout and use of land; and

(b)

Ensure proper legal descriptions and documentation of subdivided land.

9-500.030 - STATEMENT OF POLICY

It is the policy of San Joaquin County that:

(a)

County Control. The subdivision and subsequent development of land shall conform to the General Plan, any applicable Special Purpose Plan, Specific Plan or Master Plan, and the other relevant provisions of this Title;

(b)

Safety of Development. All subdivided land should be of such character that it can be used safely for building purposes by future holders of title without unreasonable danger to health, or peril from fire, flooding, or other menace; and

(c)

Facilities and Services. Provision shall be made for drainage, sewage disposal, water, schools, parks, recreation, roads, lighting, bike paths, pedestrian connections, and other public facilities and services.

9-500.040 - APPLICABILITY; COMPLIANCE REQUIRED

The regulations set forth in this Series shall apply to all parts of subdivisions within the County and to the preparation of subdivision maps and to other maps provided for in the Subdivision Map Act. All subdivisions and parts of subdivisions lying within the County shall be made, and all subdivision maps shall be prepared and presented for approval, as provided for and required by this Series.

No land shall be used, nor any building be constructed, on any lot or parcel not in conformance with this Division. No permit for the construction of a building or the use of land shall be issued on a parcel of land that does not comply with the provisions of the General Plan, any applicable Special Purpose Plan, Specific Plan, this Division, and the Subdivision Map Act. At the time of issuance of a permit, the applicant shall submit evidence that the parcel of land complies with this Division and the mandatory provisions of the current Subdivision Map Act, and a certification shall be required from Environmental Health Department as to the adequacy of the parcel to meet sanitary requirements, if necessary.

This Series shall not apply to, affect, or modify any subdivision or part of a subdivision, lawfully created and recorded prior to the effective date of this Title, or to any approval or conditions of approval of any map approved prior to the effective date of this Title. This Series is also inapplicable to actions that the Subdivision Map Act specifically excludes from its provisions including, but not limited to, the following:

(a)

Financing or Leasing of Buildings. The financing or leasing of apartments, offices, stores, or similar space within apartment buildings, industrial buildings, commercial buildings, mobile home parks, or trailer parks.
