The following residential zones are established:
A. R-1 (single-family residential) is designed for neighborhoods of single-family type residences on individual lots. Minimum lot sizes within the R-1 zone are further described in § 15.08.050 and as they appear on the Zoning Map.
B. R-1P (single-family residential preservation) is designed for mature single-family neighborhoods where the existing housing and environment is a valuable asset to the city and should be preserved.
C. R-2 (two-family residential) is designed for neighborhoods where a limited increase in population density is acceptable by permitting two dwelling units on a single lot. This zoning is applicable primarily to older neighborhoods with deep lots.
D. R-2P (two-family residential preservation) is designed for mature neighborhoods where the existing housing and environment is a valuable asset to the city and should be preserved, and where a limited increase in population density is acceptable by permitting two dwelling units on a single lot. Opportunities for additional and replacement housing are also provided where appropriate.
E. R-G (garden-type multiple-family residential) is designed for neighborhoods where limited-density apartment and condominium development must fit compatibly within an area of single-family type residences.
F. R-3R (restricted multiple-family residential) is designed for use where limited density apartment and condominium development must fit compatibly in close proximity to an area of single-family type residences.
G. R-3P (multiple-family residential preservation) is designed for mature neighborhoods where the existing housing and environment is a valuable asset to the city and should be preserved, while opportunities for additional and replacement housing are also provided where appropriate.
H. R-3 (limited-density multiple-family residential) is designed for use where apartment and condominium development can be physically separated from single-family type residences by a street or terrain feature.
I. R-4 (medium-density multiple-family residential) is designed for use where physical separation from single-family residential areas is possible, where proximity to shopping and service centers is available, and where frontage exists on major, primary, or secondary collector streets for facilitating the flow of heavier residential traffic.
J. R-5 (maximum-density multiple-family) is designed for high-rise apartments and condominiums to meet the specialized needs for high-density housing. Locations that would be close to the colleges or to central business districts and isolated where possible from single-family residential areas are considered most appropriate for such high-density zoning.
K. R-MH (Mobile Home Park) is designed for mobile home neighborhoods and compatible activities associated therewith.
