San Ramon LogoAbout Subdivisions


    What is a Subdivision?

    In general, land cannot be divided in California without local government approval. Dividing land for sale, lease or financing is regulated by local ordinances based on the State Subdivision Map Act (commencing with Government Code Section 66410).

    The City of San Ramon General Plan, Zoning, Subdivision, and other ordinances govern the design of the subdivision, the size of its lots, and the types of improvements (street construction, sewer lines, drainage facilities, etc.).

    There are basically two types of subdivisions:

    1. Parcel maps, which are limited to divisions resulting in fewer than five lots (with certain exceptions), and

    2. Subdivision maps (also called tract maps), which apply to divisions resulting in five or more lots.


    Key Questions

    • Is the proposed map consistent with the general plan and any applicable specific plans?

    • Is the site physically suited for the proposed type and density of development?

    • Is the design of the subdivision or type of improvements unlikely to cause serious public health problems?

    • Have adequate conditions been applied to the approval (or the project redesigned) to mitigate the environmental effects identified in the environmental analysis done for the project?

    • Are all dedications and impact fees reasonably related to the impacts resulting from the subdivision?

Decision-Making Process

Decision-makers want to hear from those who have opinions or information about whether to approve a Development Plan.  If you want to share your thoughts, see “Suggestions for Providing Effective Testimony at a Planning Commission Public Hearing”
