18.20.010 General purpose.

The purpose of the residential zone districts is to provide a range of housing intensities for people of different income levels in Calimesa, as well as other limited land uses appropriate for a residential setting, consistent with the general plan, and to establish appropriate standards to protect the public health, safety, welfare, and aesthetics. The districts described in this chapter are created in order for the following to be achieved:

A. Ensure adequate light, air, privacy, and open space for each dwelling.

B. Protect residential uses from excessive noise, illumination, unsightliness, odor, smoke, and other objectionable influences.

C. Facilitate the provision of utility services and other public facilities commensurate with the anticipated increase in population, dwelling unit densities, and service requirements.

D. Facilitate the establishment and operation of other small uses appropriate for placement in a residential setting. [Ord. 342 § 3 (Exh. A), 2016; Ord. 328 § 5 (Exh. C), 2014; Ord. 285 § 4, 2009; Ord. 95-7 § 2; Code 1990 § 12.3.01.]

18.20.020 Residential zone districts.

A. Open Space Residential (O-S-R) Zone. The zone is intended to preserve open space while allowing for limited detached single-family development. The terrain in this zone is unsuitable for a higher density due to steep slopes limiting sound pad areas on which to build. The minimum lot size in this zone is 10 acres.

B. Residential Estate (R-E) Zone. The zone is intended to provide for the development of single-family detached homes, and buildings and structures related to agriculture, farm use, animal keeping, and equestrian uses. The minimum lot size in this zone is five acres.

C. Rural Residential (R-R) Zone. The zone is intended to provide for the development of single-family detached dwellings and related agricultural uses on rural-sized lots and for such accessory uses as are related, incidental, and not detrimental to the rural residential environment. No more than two single-family dwellings per gross acre are permitted. The minimum lot size for this zone is 20,000 square feet.

D. Residential Low (R-L) Zone. The zone is intended to provide for and protect the atmosphere and lifestyle associated with detached, single-family residential neighborhoods. No more than four dwellings per gross acre are permitted. The minimum lot size for this zone is 7,200 square feet.

E. Residential Low/Medium (R-L-M) Zone. The zone is intended to provide for the development of small-lot single-family detached dwellings. No more than seven dwellings per gross acre are permitted. The minimum lot size for this zone is 6,000 square feet.

F. Residential Medium (R-M) Zone. The zone is intended to provide for the development of higher-density housing types. Included housing types are single-family detached, single-family attached, and multifamily homes such as duplexes, condominiums, townhouses, apartments, and senior citizen housing developments. This zone is situated in areas served adequately by infrastructure, allowing a maximum of 14 dwellings per gross acre. The minimum lot size is 6,000 square feet.

G. Residential High (R-H) Zone. The zone is intended to provide housing opportunities for people of low and moderate incomes in the form of attached or apartment-like living accommodations. The minimum lot area is 6,000 square feet, with a maximum of 20 dwelling units per gross acre. [Ord. 342 § 3 (Exh. A), 2016; Ord. 328 § 5 (Exh. C), 2014; Ord. 95-7 § 2; Code 1990 § 12.3.02.]

18.20.030 Use regulations for residential districts.

Table 18.20.030 provides a list of those uses in the residential zone districts which are permitted (P), subject to a conditional use permit (C), or prohibited (X). A minor development plan or major development plan may be required in accordance with Chapter 18.90 CMC, Development Plan Review.

C. Bed and Breakfast Inns.

1. Bed and breakfast inns shall be subject to the following requirements:

i. The permit to operate is granted solely to the property owner. If a change of ownership occurs, a new application shall be required.

j. Satisfactory evidence of compliance with state and local laws in other land use endeavors, if any, shall be provided by the owner as a prerequisite to any approvals under this chapter.

d. Any sign shall be reviewed as part of the conditional use permit application, and shall not exceed four square feet in area. If not attached to the residence, a sign shall not exceed three feet in height. One sign shall be permitted. Wording such as “motel,” “hotel,” “motor hotel,” or “lodge” shall not be permitted. The establishment may be referred to as an “inn.” The sign may be lighted externally. Lighting shall be turned off between 10:00 p.m. and 6:00 a.m.

e. Number of Rooms.

i. In the single-family residential zones, the number of guest rooms shall not exceed one room for each multiple of minimum lot area required for each dwelling unit in the underlying zone, with a maximum number of 10.

ii. In the multiple-family residential zones, the maximum number of rooms shall be determined by the adequacy of the parcel to provide on-site parking and outdoor living space.

f. The planning commission may, at the time of application, determine a reasonable maximum limit to the total number of guests staying at the inn.
