The project site, an approximately 4,088 square foot legal lot, currently is developed with 2,537 square foot two-story single-family home, a 97 square foot covered patio attached to the rear elevation of the house, a 237 square foot covered wrap-around porch attached at the front and side elevations of the house, and a 452 square foot two-car garage. The preliminary review application consists of a proposal to: 1. Convert 63 square feet of the existing 97 square-foot covered patio into living area to accommodate a new spiral staircase (through two floors) and elevator (through three floors); 2. Adding 137 square feet of new covered patio (within the lots private recreation area); 3. Adding 207 square feet of new 2nd floor balcony (within the lots private recreation area); 4. Adding an 800 square foot, two-story attached ADU; and 5. Adding a 596 square foot basement (w/ 20 square foot light well) In response to your application, the Planning Division has prepared this comment letter. Please note that the purpose of a preliminary review is to provide you with direction and comments on the overall concept of your project. This preliminary review does not represent an in-depth analysis of your project. It is intended to give you feedback on critical issues based upon the information provided in your submittal. This review is based upon the plans, policies, and standards in effect as of the date of this review. Please be aware that at the time of a formal application submittal, new plans, policies, and standards may be in effect and additional issues of concern may be raised through a more specific and detailed review. Planning: General 1. General Plan and zoning designations for the property are as follows: a. General Plan: R-8, Residential b. Zoning: Planned Community (P-C) Community Development Department Planning Division I 1635 Faraday Avenue Carlsbad, CA 92008-73141760-602-4600 I 760-602-8560 f I www.carlsbadca.gov PRE 2021-0032 (DEV2021-0181) -7290 CALLE TARI FA REMODEL AND ADDITION September 27, 2021 Pa e 2 c. Master Plan: La Costa Master Plan (AMEND2017-0012). The subject property is located within Neighborhood SE-14 of the La Costa Master Plan and was originally approved as part of project named: La Costa Residential -CT 12-05/PUD 12-07 /V 12-02. The La Costa Master Plan designates Neighborhood SE-14 with Residential Density-Multiple (RD-M) Zoning. 2. The project requires the issuance of both a building permit and grading permit. 3. Lot Coverage. The subject site was developed as a small lot PUD with a lot size of less than 5,000 square feet. Therefore, pursuant to Section 21.45.070 of the Carlsbad Municipal Code (CMC), the subject site has a maximum lot coverage requirement of 50 percent. Per CMC 21.04.061, the perimeter area of a basement is included in the lot coverage. The project proposes a basement for a home theater as part of the main dwelling but is not including it in the total lot coverage for the site. Further, per state laws governing ADUs, an ADU is only exempt from lot coverage provided that the ADU meets a side and rear yard setback of four (4) feet and a height limit of 16 feet. As proposed, the attached 800 square foot ADU meets the setback requirements; however, the two-story ADU exceeds this height limit and therefore is subject to the lot coverage requirements. Any plans submitted for building plan check must provide a lot coverage breakdown that includes all applicable items listed under the definition of building coverage as outlined in Section 21.04.061 of the Carlsbad Municipal Code (CMC). 4. Private Rear Yard. Pursuant to CMC Section 21.45.070, the rear yard of the primary dwelling must maintain a private recreational area with a minimum area of 400 square feet a minimum dimension of 15 feet and shall be located at ground level and designed so as to be functional, usable, and easily accessible from the dwelling it is intended to serve, and shall not have a slope gradient greater than 5%. As proposed, the project would not meet the minimum dimensions for a private rear yard area. The proposed ADU would reduce the private rear yard requirement. The proposed project is subject to this requirement because the ADU does not qualify as a mandatory approval (exempt from development standards that preclude the construction of an ADU) because the height of the ADU exceeds 16 feet. Further, CMC Section 21.45.070 only allows for balconies that project into the required private recreational space if the depth of the projection does not exceed six feet, measured from the wa II of the dwelling that is contiguous to the balcony. The length of the project is not limited; however, it must meet lot coverage standards. Any plans submitted for plan check must clearly label the dimension of the depth of the balcony to show compliance with this standard . . All necessary application forms, submittal requirements, and fee information are available at the Planning counter located in the Faraday Building at 1635 Faraday Avenue or on line at https://www.carlsbadca.gov/departments/community-development/planning. You may also access the General Plan Land Use Element and the Zoning Ordinance online at the website address shown.
