Morgan Hill City Zoning Code

CHAPTER 18

16 - RESIDENTIAL DETACHED ZONING DISTRICTS

18.16.010 - Purpose of the residential detached zoning districts.

A.

General. The purpose of the residential detached zoning districts is to support attractive, safe, and friendly single-family residential neighborhoods consistent with Morgan Hill's unique small-town feel. Development within the residential detached zoning districts features high quality design that enhances the visual character of the community. The mass, scale, and design of new homes support pleasant and walkable neighborhoods that complement Morgan Hill's existing community character.

B.

Specific.

1.

Residential Estate (RE). The purpose of the RE zoning district is to provide locations for detached single-family homes on large lots in a semi-rural setting. The RE zoning district is divided into three subzones allowing for a range of permitted residential densities.

2.

Residential Detached Low Density (RDL). The purpose of the RDL zoning district is to provide locations for detached single-family homes in low-density single-family neighborhoods. The RDL zoning district is divided into two subzones allowing for a range of permitted residential densities.

3.

Residential Detached Medium Density (RDM). The purpose of the RDM zoning district is to provide locations for detached single-family homes and a limited number of duet units in medium-density single-family neighborhoods. The RDM zoning district is divided into two subzones allowing for a range of permitted residential densities.

4.

Residential Detached High Density (RDH). The purpose of the RDH zoning district is to provide locations for detached single-family homes on small lots and a limited number of duet units in high-density single-family neighborhoods.

(Ord. No. 2277 N.S., § 5(Exh. A), 6-6-2018)

B.

Additional Permits. In addition to permits identified in Table 18.16-1, proposed projects in the detached residential zoning districts may also require a design permit pursuant to Section 18.108.040 (Design Permits). Modifications to a historic resource may require a Historic Alteration pursuant to Chapter 18.60 (Historic Resources).

C.

Residential Building Allotments. All residential development must comply with the voter-approved residential development control system (RDCS) as established in Chapter 18.78 (Residential Development Control System). The RDCS requires proposed residential projects to first receive residential building allotments before applying for land use entitlements. Section 18.78.050.C (Exemptions from Allotments) identifies types of residential projects exempt from the requirement to obtain residential building allotments.
