The purpose of this zone is to stabilize and protect the residential characteristics of the areas so designated and to promote and encourage a suitable environment for family life. The R-1 zone is basically intended to provide communities primarily for single-family detached homes and the services appurtenant thereto. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1212 § 1, 1969; prior code § 33.503(A)).

Principal permitted uses in the R-1 zone include:

Accessory uses permitted in the R-1 zone include:

The following uses shall be permitted in the R-1 zone; provided, a conditional use permit is issued in accordance with the provisions of CVMC 19.14.030(A) or 19.14.040, as may be applicable, and CVMC 19.14.050 through 19.14.090:

The following uses shall be permitted in the R-1 zone; provided, a conditional use permit is issued by the Planning Commission, or for unclassified uses as defined in CVMC 19.54.020:

Repealed by Ord. 2924 § 3, 2003. (Ord. 1575 § 1, 1974; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(E)).

Principal buildings may not exceed two and one-half stories or 28 feet in height; however, an increase in building height may be allowed subject to approval of a variance. No accessory building shall exceed one and one-half stories or 15 feet in height except as provided in CVMC 19.16.040 and 19.58.022. The height of a residential structure is measured from the highest point of the roof line to finished grade. (Ord. 3503 § 3, 2021; Ord. 3153 § 2 (Exh. A), 2010; Ord. 2144 § 3, 1986; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(F)).

Area, lot width, and yard requirements in the R-1 zone are as follows (see CVMC 19.16.020, 19.16.050, 19.16.060 and 19.16.080 for exceptions and modifications):

The R-1-7 zone classification and the minimum dimensions requirement prescribed for said classification shall be considered to be the basic or standard lot size throughout the City; provided, however, that in those areas placed in the R-1-7 classification, if a subdivision map is filed, the minimum lot sizes for 20 percent of the lots created by said subdivision may be reduced to 6,000 square feet, and 10 percent of the lots thus created may be reduced to 5,000 square feet, said lots being subject to those minimum dimensional requirements as set forth hereinabove for such lot areas; provided, that the average lot size of all the lots within the subdivision shall equal a minimum of 7,000 square feet. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1500 § 2, 1973; Ord. 1212 § 1, 1969; prior code § 33.503(H)(1)).

The incorporation of any properties into the R-1-5 classification shall be restricted to those areas deemed most appropriate in accordance with the basic principles set forth herein. Particular attention will be given to the character of the topography involved so as to ensure the capability of accommodating lots of this size in a manner that would provide appropriate usable level space for each lot. The filing and approval of a final subdivision map will be required prior to any such R-1-5 zoning becoming effective, and in addition, a precise plan may be required as provided in CVMC 19.12.120. Said map should ensure that the density of the subdivision will be properly related to that existing or proposed in surrounding areas, and that the development will not be incompatible with sound neighborhood density standards, and further, that public facilities will not be overburdened. Open space should be provided or available in the form of natural canyons, green belts, park areas or such other forms which would contribute to better land use and design and accommodate the recreational needs of families who would be living in areas designated for 5,000 square foot minimum lot sizes. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1212 § 1, 1969; prior code § 33.503 (H)(2)).

Front and side yard setback requirements for particular zone classifications shall be provided and maintained in accordance with the schedule set forth hereinabove, or in accordance with those specified in the building line map. Those setback requirements as shown on the adopted building line map of the City shall be adhered to in any case where said requirements differ from setbacks established in said schedule. Furthermore, regardless of any minimum side yard requirements as indicated in said schedule, the minimum distance between dwelling units shall be 10 feet, and no dwelling unit may be constructed closer than three feet to any side property line with the exception of the R-1-5 zone classification which shall maintain a minimum of five feet. Said minimum three-foot dimension shall be measured on a horizontal plane on the level of the foundation of the dwelling unit. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(I)(1)).

Every lot in the R-1 zone having an area between 5,000 square feet and 5,999 square feet shall have a minimum lot frontage upon a dedicated street of 50 feet, and every lot having an area of 6,000 square feet or greater shall have a minimum lot frontage upon a dedicated street of 60 feet, unless such lots front upon an approved easement or private road as provided for in this chapter (see CVMC 19.24.170) or unless such lots have been approved by the Planning Commission or City Council pursuant to the provisions of this code or any ordinance which may hereafter be enacted providing for the subdivision of land or the dedication of public streets. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1868 § 1, 1979; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(I)(2)).

In the R-1 zone, single-story structures attached to the main building may be located within 10 feet of the rear property line, but shall not be closer than five feet from any retaining wall or toe of slope and said structure shall not occupy more than 30 percent of the rear yard area. Rear yards that have an elevation difference of six feet or more from the adjoining lot or parcel may reduce said 10 feet one foot for every foot over six feet but not more than five feet. Two-story portions of the building shall not be closer than the required rear yard setback. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(I)(3)).

Minimum floor area in the R-1 zone shall be as follows:

Exception: Except in the case of the 1,000 square feet dwelling units, an applicant may reduce the above minimums by 200 square feet per unit for 30 percent of the dwellings within an approved subdivision; provided, the average house size within the development conforms to the minimum requirements specified above. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1500 § 3, 1973; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(J)).

The two-car garage requirement applies in the R-1 zone (see CVMC 19.62.170 through 19.62.190 for garage requirements and conversions). (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(K)).

All uses in the R-1 zone may be subject to the initial and continued compliance with the performance standards in Chapter 19.66 CVMC. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(L)).

See CVMC 19.58.150 for fencing requirements in the R-1 zone. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.503(M)).

Panhandle lots, flag lots, or lots served by an easement shall be provided in the R-1 zone subject to the requirements and conditions of CVMC 19.22.150. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 1868 § 2, 1979).

Construction of dwellings or any remodeling or additions to existing dwellings shall have a floor area ratio (FAR) which limits the maximum building area to 45 percent of the lot area for single-family dwellings on lots of 7,000 square feet or greater and 50 percent of the lot area or 3,150 square feet, whichever is less, for single-family dwellings on lots of less than 7,000 square feet. The floor area ratio calculation shall also include the square footage of patios, garages and other accessory structures present on the lot, but excluding covered patios open on at least two sides and covered porches open on at least one side with a total combined area of 300 square feet or less. For these purposes, an “accessory structure” is defined as any structure which rises four or more feet above finished grade. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 2559 § 4, 1993; Ord. 2144 § 3, 1986).

See CVMC 19.22.170 for limitations to remodeling or additions to existing dwellings. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 2144 § 3, 1986).
