RESIDENTIAL COASTAL ZONING DISTRICTS (R-A, R-1, R-BI, R-2, and RM)

Sections:

21.18.010    Purposes of Residential Coastal Zoning Districts.

21.18.020    Residential Coastal Zoning Districts Land Uses.

21.18.030    Residential Coastal Zoning Districts General Development Standards.

21.18.010 Purposes of Residential Coastal Zoning Districts.

The purposes of the individual residential coastal zoning districts and the manner in which they are applied are as follows:

A.    R-A (Residential-Agricultural) Coastal Zoning District. The R-A Coastal Zoning District is intended to provide for areas appropriate for detached single-family residential dwelling units and light farming uses, each located on a single legal lot, and does not include condominiums or cooperative housing.

B.    R-1 (Single-Unit Residential) Coastal Zoning District. The R-1 Coastal Zoning District is intended to provide for areas appropriate for a range of detached single-family residential dwelling units, each located on a single legal lot, and does not include condominiums or cooperative housing.

C.    R-BI (Two-Unit Residential, Balboa Island) Coastal Zoning District. The R-BI Coastal Zoning District is intended to provide for a maximum of two residential dwelling units (i.e., duplexes) located on a single legal lot on Balboa Island.

D.    R-2 (Two-Unit Residential) Coastal Zoning District. The R-2 Coastal Zoning District is intended to provide for areas appropriate for a maximum of two residential dwelling units (i.e., duplexes) located on a single legal lot.

E.    RM (Multiple Residential) Coastal Zoning District. The RM Coastal Zoning District is intended to provide for areas appropriate for multi-unit residential developments containing attached or detached dwelling units. (Ord. 2016-19 § 9 (Exh. A)(part), 2016)

21.18.020 Residential Coastal Zoning Districts Land Uses.

A.    Allowed Land Uses.

1.    Table 21.18-1 indicates the uses allowed within each residential coastal zoning district.

2.    Residential uses represent the primary allowed use, and only those additional uses that are complementary to, and can exist in harmony with, the residential character of each coastal zoning district may be allowed as accessory, conditionally permitted, and/or temporary uses.

B.    Prohibited Land Uses. A table cell with “—” means that the listed land use is prohibited in that coastal zoning district.

C.    Applicable Regulations. The last column in the table (“Specific Use Regulations”) may include a reference to additional regulations that apply to the use.
