(A)   All buildings hereafter erected and existing buildings which may be reconstructed, altered, moved or maintained or enlarged shall comply with the area regulations of the zone in which they may be located.

   (B)   The lot area shall be that prescribed by this title and shall not be reduced, diminished or maintained so that the yard or open spaces are smaller than that prescribed by this title, and the density of population shall not be increased in any manner, except in conformity with the area regulations of the zone in which it is located.

   (C)   Except as provided in § 17.98.020, every building and structure hereafter erected, and every use hereafter undertaken in any zone, shall be located and conducted only on a legal lot which has been surveyed and had monumentation set (as certified by a registered civil engineer or licensed land surveyor), and only within the lot lines of such legal lot. A building or structure may be erected and a use may be conducted across the lot lines of contiguous lots and legal lots, however, if the lots are owned by the same person or persons as an undivided and nonfractional interest; provided, that any such building or structure erected and use being conducted across any lot line shall be in accordance with the property development standards of the zone in which the lots are located and general conditions provided in this chapter as the standards and conditions apply to each lot, the lot line of which is so crossed, with the exception that the following property development standards and general conditions do not apply to those lots which do not constitute the exterior lots of the series of lots over which such building or structure is erected or use is conducted; yards and distance between buildings (insofar as such standards relate to side yards); lot coverage and walls, fences and landscaping (insofar as said standards apply to interior lots and lot lines).

   (D)   The minimum lot width and depth allowed in single-family residential zones shall be that described in the respective zone or Specific Plan land use designation. Residential zones and/or Specific Plan land use designations that require a minimum lot size of 200 square feet shall have a minimum lot width of 65 feet. In addition to the minimum lot width requirement, the R-1-7.2 zone shall have an average lot width requirement of 70 feet in residential subdivisions, the R-1-8.4 zone shall have an average lot width requirement of 75 feet in residential subdivisions, and the R-1-9.6 zone shall have an average lot width requirement of 80 feet in residential subdivisions. This average lot width requirement is also applicable to Specific Plans with similar land use designations, as determined by the minimum lot size requirement of that designation. Minimum lot size requirements falling in between the R-1-7.2, R-1-8.4 and R-1-9.6 zones shall use the minimum lot width and average lot width requirements of the preceding zone (9,000 square foot minimum lot size will use the R-1-8.4 lot width requirements). The lot width requirements stated above apply to all legally created lots in the city as described in § 17.64.015 (Lots- Single-Family Residential).

   (E)   The lot area coverage by single-story buildings or structures on legal lots that are 9,600 square feet in area or smaller, and do not otherwise satisfy the minimum lot area requirement of the residential zone in which the lot is located, shall not exceed 45% of the total lot area. The lot area coverage by two-story buildings or structures on legal lots that are 9,600 square feet in area or smaller, and do not otherwise satisfy the minimum lot area requirement of the residential zone in which the lot is located, shall not exceed 35% of the total lot area.

(`78 Code, § 17.64.010.) (Ord. 3291 § 9, 2018; Ord. 2850 § 1, 2006; Ord. 2428 § 4, 1999; Ord. 1864 § 2, 1987; Ord. 1544 § 1, 1979.)

   The minimum lot area available for single-family residential use on and after the effective date of the initiative known as Measure H and submitted to the voters at the election of November 4, 1986 shall be 7,200 square feet. Notwithstanding any contrary provision contained in this code, no tentative map, vesting tentative map, parcel map, development plan, Specific Plan, Specific Plan amendment, resubmitted tentative or parcel map or proposed planned unit development which creates or provides for the creation of single-family residential lots smaller than 7,200 square feet in area shall be approved, adopted or accepted for review on or after the effective date of the Measure H. This section shall not affect the privilege or right of any person to proceed with construction on lots approved pursuant to the subdivision process or proposed under any adopted Specific Plan prior to the effective date of the Measure H or on any legally created residential lot in existence prior to the date. An adopted Specific Plan that existed prior to the effective date of Measure H may be amended without affecting the ability to proceed with construction on lots proposed under the original adopted Specific Plan, provided that no additional new lots smaller than 7,200 square feet in area are authorized by the amended Specific Plan. An approved tentative map may be revised and resubmitted, provided that the resubmitted map creates no additional new lots smaller than 7,200 square feet in area. Notwithstanding the preceding sentence, a revised tentative map may create additional new lots smaller than 7,200 square feet if such additional lots were authorized under a Specific Plan adopted prior to the effective date of Measure H. Nothing in this section shall be construed as reducing the currently established minimum lot areas in any of the city’s zoning districts.

(`78 Code, § 17.64.015.) (Ord. 1871 § 2, 1988.)

   The use of septic tanks or other waste disposal systems in lieu of using the city's sewer system is prohibited on lots that are less than 14,400 square feet in size. Lots less than 14,400 square feet may be allowed the use of a septic system or other alternative waste disposal system if the property is determined to have the following limitations and criterion. This determination is subject to approval by the directors of the Planning and Public Works Departments, and Department of Water and Power.

   (A)   The property is considered an in-fill development because it is bound by existing developed properties, preventing the property owner from having the ability to acquire additional properties to meet the minimum lot size of 14,400 square feet.

   (B)   The property is located in an area in which there is insufficient infrastructure to serve the property.

   (C)   The property can be graded in a manner to accommodate septic tanks or other waste disposal systems including leech lines and seepage pits, in which the system is located underground and properly covered, and poses no impacts to neighboring properties.

(Ord. 2850 § 1, 2006) (Ord. 2850 § 1, 2006)

   (A)   Yards shall be measured perpendicular to the property line or from a future street or highway line as shown on the General Plan or established in the setback ordinance.

   (B)   Yard provisions shall apply to both main and accessory structures unless otherwise specified.

   (C)   No required yard or other open space around an existing building or any building hereafter erected shall be considered as providing a yard or other open space for any other building on an adjoining lot or building site.

   (D)   Garage doors shall not, when open or being opened, project beyond the lot line.

A guard railing around depressed ramps for personal safety protection may be located in any front, side or rear yard; provided, however, the railing does not exceed three feet in height at any one point.

   (B)   Fire escapes may extend or project into any yard not more than four feet; provided, however, that the yard shall not be reduced to less than three feet in clear width.

   (C)   Cornices, canopies, eaves, belt courses, sills and other similar architectural features may extend or project into a required front yard not more than four feet and may extend into a required side or rear yard not more than six inches for each one foot of width of such required side or rear yard.

   (D)   Uncovered porches, platforms or landing places which do not extend above the level of the first floor of the building may extend into any front yard a distance of not more than 20% of such front yard and in no instance more than five feet. Such features may not extend into a court more than 20% of the width of said court and in no case more than five feet and may extend into any side or rear yard not more than four feet. An openwork railing may be installed or constructed on any such portion, platform or landing place provided it does not exceed 30 inches in height.

      (1)   Key lots shall have a front yard not less than the front yard for the adjoining interior lot. When the front yard on the adjoining interior lot is less than prescribed by this title, the key lot front yard may be the same, but shall in no case be less than 20 feet;

      (2)   In partially built up blocks, no front yard need be deeper than the average depth of the front yards next thereto on each side, but shall in no case be less than 20 feet.

      (2)   Swimming pools shall not be permitted in any required front yard. Pump or filter installation for such swimming pools shall be made not less than ten feet from an adjoining property line except where a five foot high block wall is maintained extending a distance of two feet on each side of such equipment and situated either between such equipment and said property line or on said property line.

      (3)   Notwithstanding anything contrary stated in this code, except as provided in Chapter 17.86, all lots, which are zoned residential or agricultural and bear a prefix designation on the city’s official zoning map commencing with the letter "R" or "A" and on which dwellings are constructed so as to front on a major or secondary street and highways, as said streets and highways are defined in the city’s General Plan and report and delineated on the city’s General Plan map, shall have a front yard at least 30 feet in depth.
