CHAPTER 18

12 – Residential Zones R-R, R-1, R1-5000, R-2, R-3, R-4, M-H

18.12.010 – Purpose of Residential Zones

  • The purpose of this Chapter is to achieve the following:
    1. Provide a range of residential zones with appropriate site location criteria and high-quality development standards subject to Community Plans.
    2. Promote a suitable environment for single- and multi-family living and allow community-oriented uses (i.e., schools, churches, parks, and playgrounds).
    3. Ensure compatibility of residential zones with adjacent land uses.
  • The purpose of the individual residential uses and the way they are applied are as follows.
    1. R-R Rural Residential Zone. The purpose of the R-R Rural-Residential Zone is to provide areas for rural residential development, hobby farming, and limited animal raising operations with less than a full range of urban services. It is intended that this zone typically serve as a transitional area between denser urban communities and agricultural uses, allowing one to three dwelling units per acre. This zone implements the Agriculture Residential (AR) and Very Low Density Residential (VLDR) land use designations in the General Plan.
    2. R-1 Single-Family Residential Zone. The purpose of the R-1 Single-Family Residential Zone is to provide a full range of urban services and reserve appropriately located areas for single-family living with low population densities consistent with sound standards of public health, welfare, and safety. It is the intent of this zone to protect the residential characteristics of an area and to promote a suitable environment for family life. This zone implements the Very Low Density Residential (VLDR), and Low Density Residential (LDR) land use designations in the General Plan.
    3. R-1-5000 Single-Family Residential Zone. The purpose of the R-1-5000 Single-Family Residential Zone is to provide a full range of urban services and reserve appropriately located areas similar to the R-1 Zone for single-family living at slightly higher population densities consistent with sound standards of public health, welfare, and safety. It is the intent of this zone to protect the residential characteristics of an area and to promote a suitable environment for family life. This zone implements Medium Density Residential (MDR) in some community plans and implements the Low Density Residential (LDR) land use designation in the General Plan.
    4. R-2 Two-Family Residential Zone. The purpose of the R-2 Two-Family Residential Zone is to provide for areas with a full range of urban services for two residential dwellings per parcel in the form of two detached single-family dwellings, duplexes, town houses, and other forms of medium-density residential development, and to maintain a residential character similar to that found in single-family neighborhoods. The intent is to ensure compatibility of duplex-type development with surrounding multi- and single-family residences and the local neighborhoods. This zone implements the Medium Density Residential (MDR) land use designation in the General Plan.
    5. R-3 Multi-family Residential Zone. The purpose of the R-3 Medium-Density Multi-family Residential Zone is to provide areas for residential neighborhoods consistent with the Medium-Density standards of the General Plan (typically up to 15 dwelling units per gross acre) and with a full range of urban services. This zone provides for both rental and ownership housing opportunities which are often an affordable alternative to single-family neighborhoods. Dwelling types may include grouped or clustered multi-family dwellings (i.e., duplexes, triplexes, townhouses, apartments), and other multi-family attached dwelling units (i.e., condominiums). It is intended that new development in this zone use innovative site planning, provide on-site recreational amenities, encourages walking and connectivity to surrounding land uses and be located near major community facilities, business centers, public transportation, and/or major streets. This zone implements the Medium Density Residential (MDR) land use designation in the General Plan.
    6. R-4 Multi-family Residential Zone. The purpose of the R-4 High-Density Multi-family Residential Zone is to provide areas for residential neighborhoods consistent with the High-Density standards of the General Plan (typically up to 33 dwelling units per gross acre) and with a full range of urban services. Dwelling types may include grouped or clustered multi-family dwellings (i.e., duplexes, triplexes, apartments), and other multi-family attached dwelling units, including boarding and rooming houses. It is intended that new development in this zone use innovative site planning, provide on-site recreational amenities and be located near major community facilities, business centers, and/or major streets. This zone implements the High Density Residential (HDR) land use designation in the General Plan.
    7. M-H Single-Family Mobile Home Residential Zone. The purpose of the M-H Single-Family Mobile Home Residential Zone is to provide areas for residential living designed exclusively for mobile/manufactured home dwelling units and tiny homes not on a permanent foundation within an Urban Community where public water and sewer are available and with a full range of urban services. This zone implements the Medium-Density Residential (MDR) land use designation in the General Plan.

    18.12.030 – Residential Zone Development Standards

  • Table 2-4 Residential Zone Development Standards. The intent of the residential zone development standards table is to clearly and precisely establish the basic site and structure regulations that apply to all developments in each of the residential zones. The table also indicates where additional site and structure requirements, including, but not limited to, off-street parking, landscaping, signing, fences and obstructions, and performance standards, apply to residential zones.
  • Increased Setbacks Use Permits. The setbacks listed below may be increased for those uses requiring an Administrative or Conditional Use Permit when it is determined by the Commission or Director, as applicable, that increased setbacks are necessary to make the use compatible with surrounding properties and uses.
  • Density. Maximum density standards shall be consistent with the General Plan or applicable community plan.
  • Zoning Map. The boundaries, designations, and locations of the zones established by this Zoning Code shall be shown on the map(s) entitled "Zoning Map for Merced County" and referred to in this Zoning Code as the Zoning Map. Any additional maps (e.g., setback map) adopted shall also be a part of this Zoning Code by reference. This Zoning Code, together with the Zoning Map, is hereby adopted in compliance with current State planning, zoning, and development laws. Changes in the boundaries of any identified zones shall be made by ordinance in compliance with Chapter 18.142 (Amendments).
