20.22.040 - Urban residential (/UR) overlay zone.

A. Purpose. The /UR overlay zone is intended to encourage high quality residential development in Merced's downtown and other urban neighborhoods. The overlay zone identifies permitted residential building types that reflect the traditional scale and character of these neighborhoods. These building types are permitted in addition to the use allowed by the underlying base zoning district. The /UR overlay zone increases choices for property owners and residents, promotes high quality design, and supports a vibrant and welcoming downtown area.

B. Site Plan Review or Minor Use Permit Required. A site plan review or minor use permit shall be required per Table 20.22-1 for the construction of permitted residential building types that do not conform to the standards of the base zoning district.

C. Building Types.

  1. Building Type Defined. A building type is a particular kind of structure with its own recognizable identity. Building types are defined primarily by their form (mass, scale, and design) with building function being of secondary importance.

  2. Permitted Building Types. Permitted residential building types in the /UR overlay zone are based on the underlying base zoning district. Table 20.22-1 (Permitted Residential Building Types) identifies permitted residential building types in the /UR overlay zone by residential zoning district.
