San Diego Municipal Code § 131.0401 Purpose of Residential Zones

§131.0401 Purpose of Residential Zones The purpose of the residential zones is to provide for areas of residential development at various specified densities throughout the City. The residential zones are intended to accommodate a variety of housing types and to encourage the provision of housing for all citizens of San Diego. It is also intended that the residential zones reflect desired development patterns in existing neighborhoods while accommodating the need for future growth. (Added 12-9-1997 by O-18451 N.S.; effective 1-1-2000.)

San Diego Municipal Code § 131.0403 Purpose of the RS (Residential--Single Unit) Zones

§131.0403 Purpose of the RS (Residential--Single Unit) Zones (a) The purpose of the RS zones is to provide appropriate regulations for the development of single dwelling units that accommodate a variety of lot sizes and residential dwelling types and which promote neighborhood quality, character, and livability. It is intended that these zones provide for flexibility in development regulations that allow reasonable use of property while minimizing adverse impacts to adjacent properties. (b) The RS zones are differentiated based on the minimum lot size and whether the premises is located in an Urbanized Community or a Planned Urbanized Community or Proposition A Lands, as follows: (1) Urbanized Communities • RS-1-1 requires minimum 40,000-square-foot lots • RS-1-2 requires minimum 20,000-square-foot lots • RS-1-3 requires minimum 15,000-square-foot lots • RS-1-4 requires minimum 10,000-square-foot lots • RS-1-5 requires minimum 8,000-square-foot lots • RS-1-6 requires minimum 6,000-square-foot lots • RS-1-7 requires minimum 5,000-square-foot lots (2) Planned Urbanized Communities or Proposition A Lands • RS-1-8 requires minimum 40,000-square-foot lots • RS-1-9 requires minimum 20,000-square-foot lots • RS-1-10 requires minimum 15,000-square-foot lots • RS-1-11 requires minimum 10,000-square-foot lots • RS-1-12 requires minimum 8,000-square-foot lots • RS-1-13 requires minimum 6,000-square-foot lots • RS-1-14 requires minimum 5,000-square-foot lots (Added 12-9-1997 by O-18451 N.S.; amended 10-18-1999 by O-18691 N.S.; effective 1-1-2000.) (Amended 4-8-2008 by O-19734 N.S; effective 5-8-2008.)

San Diego Municipal Code § 131.0404 Purpose of the RX (Residential--Small Lot) Zones

§131.0404 Purpose of the RX (Residential--Small Lot) Zones (a) The purpose of the RX zones is to provide for both attached and detached single dwelling units on smaller lots than are required in the RS zones. It is intended that these zones provide an alternative to multiple dwelling unit developments where single dwelling unit developments could be developed at similar densities. The RX zone provides for a wide variety of residential development patterns. (b) The RX zones are differentiated based on the minimum lot size as follows: • RX-1-1 requires minimum 4,000-square-foot lots • RX-1-2 requires minimum 3,000-square-foot lots (Added 12-9-1997 by O-18451 N.S.; effective 1-1-2000.)

San Diego Municipal Code § 131.0405 Purpose of the RT (Residential--Townhouse) Zones

§131.0405 Purpose of the RT (Residential--Townhouse) Zones (a) The purpose of the RT zones is to provide for attached, single-dwelling unit residential development on small lots with alley access. It is intended that these zones provide for more urbanized, single-unit living at densities that are historically more typical of multiple-unit zones. The RT zones provide transition opportunities between single-unit neighborhoods and higher density multiple-unit neighborhoods and in some instances may replace multiple-unit zones at similar densities. The RT zones are intended to be applied on subdivided blocks with alleys that are within or close to highly urbanized areas, transit areas, and redevelopment areas. (b) The RT zones are differentiated based on the minimum lot size as follows: • RT-1-1 requires minimum 3,500-square-foot lots • RT-1-2 requires minimum 3,000-square-foot lots • RT-1-3 requires minimum 2,500-square-foot lots • RT-1-4 requires minimum 2,200-square-foot lots • RT-1-5 requires minimum 1,600-square-foot lots (Added 12-9-1997 by O-18451 N.S.; effective 1-1-2000.)

§131.0406 Purpose of the RM (Residential--Multiple Unit) Zones (a) The purpose of the RM zones is to provide for multiple dwelling unit development at varying densities. The RM zones individually accommodate developments with similar densities and characteristics. Each of the RM zones is intended to establish development criteria that consolidates common development regulations, accommodates specific dwelling types, and responds to locational issues regarding adjacent land uses. (b) The RM zones are differentiated based on the uses allowed and the permitted density as follows: (1) The following zones permit lower density multiple dwelling units with some characteristics of single dwelling units: • RM-1-1 permits a maximum density of 1 dwelling unit for each 3,000 square feet of lot area • RM-1-2 permits a maximum density of 1 dwelling unit for each 2,500 square feet of lot area • RM-1-3 permits a maximum density of 1 dwelling unit for each 2,000 square feet of lot area (2) The following zones permit medium density multiple dwelling units: • RM-2-4 permits a maximum density of 1 dwelling unit for each 1,750 square feet of lot area • RM-2-5 permits a maximum density of 1 dwelling unit for each 1,500 square feet of lot area • RM-2-6 permits a maximum density of 1 dwelling unit for each 1,250 square feet of lot area (3) The following zones permit medium density multiple dwelling units with limited commercial uses: • RM-3-7 permits a maximum density of 1 dwelling unit for each 1,000 square feet of lot area • RM-3-8 permits a maximum density of 1 dwelling unit for each 800 square feet of lot area • RM-3-9 permits a maximum density of 1 dwelling unit for each 600 square feet of lot area (4) The following zones permit urbanized, high density multiple dwelling units with limited commercial uses: • RM-4-10 permits a maximum density of 1 dwelling unit for each 400 square feet of lot area • RM-4-11 permits a maximum density of 1 dwelling unit for each 200 square feet of lot area (5) RM-5-12 permits visitor accommodations or medium density multiple dwelling units at a maximum density of 1 dwelling unit for each 1,000 square feet of lot area.
