(a)   Purpose

   The purpose of a conditional use perrnit is to provide for uses and accessory uses that are necessary or desirable for the development of the community or region but cannot readily be classified as permitted uses in individual districts by reason of uniqueness of size, scope, or possible effect on public facilities or surrounding uses.

   (b)   Applicability

      (1)   A conditional use permit may be granted for any use or purpose for which such permit is required or permitted by the provisions of this title; or

      (2)   Any expansion in the building size or site area of an existing conditional use shall necessitate the amendment of the conditional use permit. Denial of an application for amendment of a conditional use permit does not constitute a revocation of the original conditional use permit.

      (3)   No application for a conditional use permit is necessary for existing uses which were lawful conforming permitted uses and which were rendered conditional by reason of rezoning or changes to this title, provided that any expansion in the building site or site area of such a use shall be subject to the issuance of a conditional use permit.

   (4)   Establishments that are allowed by the city to serve alcohol for onsite consumption by issuance of a conditional use permit (“CUP”) as required in this section or as a legal nonconforming use, and that have both an on-sale license from the Department of Alcoholic Beverage Control (“ABC”) and are duly authorized by ABC to serve alcohol in outdoor areas, shall be allowed to serve alcohol for onsite consumption without an amendment of the CUP in parklets on public property approved via permit per PAMC Chapter 12.11 or other outdoor uses approved via permit per any other relevant section of the PAMC. Outdoor alcohol service shall be in full compliance with all applicable regulations, including ABC regulations, as may be amended.

   (c)   Findings

   Neither the director, nor the city council on appeal, shall grant a conditional use perrnit, unless it is found that the granting of the application will:

      (1)   Not be detrimental or injurious to property or improvements in the vicinity, and will not be detrimental to the public health, safety, general welfare, or convenience;

      (2)   Be located and conducted in a manner in accord with the Palo Alto Comprehensive Plan and the purposes of this title (Zoning).

   (d)   Conditions

   In granting conditional use permits, reasonable conditions or restrictions may be imposed if appropriate or necessary to protect the public health, safety, genera! welfare, or convenience, to secure the purposes of this title, and to assure operation of the use in a manner compatible with existing and potential uses on adjoining properties and in the general vicinity.

   (e)   Application Review and Action

   Applications for conditional use permits shall be reviewed and acted upon as set forth in Section 18.77.060 (Standard Staff Review Process).

(Ord. 5594 § 8, 2024: Ord. 4826 § 117 (Exh. 2 (part)), 2004)

   A conditional use permit shall not be granted in a R-Combining district for a formula retail business, or a beauty shop, nail salon, barbership, or financial services use, unless it is found, in addition to the findings required by section 18.76.010, that:

      (1)   The retail or personal service business will offer merchandise and/or services that meet the underserved needs of the City’s residents and visitors.

      (2)   The type of retail or personal service business will enhance the balance and diversity of businesses in the district and in the City as a whole.

      (3)   The retail or personal service business will enhance the economic vitality of the district where the business is proposed to be located and of the City as a whole. In considering this finding, the director or city council may consider existing retail vacancy rates within the district and in the City as a whole.

      (4)   The retail or personal service business is consistent with the character of the district where the business is proposed to be located.

      (5)   The design of the retail or personal service business will be compatible with the architectural and aesthetic character of the district where the business is proposed to be located.

(Ord. 5358 § 8, 2015)

   (b)   Applicability

   No permit required under Title 2, Title 12 or Title 16 shall be issued for a major or minor project, as set forth in this section, unless an application for architectural review is reviewed, acted upon, and approved or approved with conditions as set forth in Section 18.77.070.

      (1)   Exempt Projects. The following projects do not require architectural review:

         (A)   Single-family and two-family residences, except as provided under subsections (b)(2)(C) and (b)(2)(D).

         (B)   Projects determined by the director of planning and development services to be substantially minor in nature and have inconsequential visual impacts to the adjacent properties and public streets.

         (C)   Housing development projects, as defined in Government Code section 65589.5(h)(2) (the Housing Accountability Act), but only if such projects qualify for ministerial review under Government Code section 65913.4 or 65951, or if they comply with all applicable objective standards, and the city’s discretion is thereby limited by Government Code section 65589.5.

      (2)   Major Projects. The following are "major projects" for the purposes of the architectural review process set forth in Section 18.77.070, and are subject to review by the architectural review board:

         (A)   New construction, including private and public projects, that:

            (i)   Includes a new building or building addition of five thousand square feet or more; or

            (ii)   Is not exempt under the California Environmental Quality Act (CEQA) (Section 21000 et seq. of the California Public Resources Code); or

            (iii)   Requires one or more variances or use permits and, in the judgment of the director, will have a significant effect upon the aesthetic character of the city or the surrounding area;

         (B)   Any multiple-family residential construction project that contains three or more units;

         (C)   Construction of three or more adjacent single-family homes or duplexes;

         (F) Any changes to previously approved plans requiring architectural review as a minor project as part of the conditions of a permit or approval.

   (c)   Preliminary Review

   For the purpose of securing the advice of the architectural review board prior to making an application for the board's recommendation on a project, an applicant, upon paying a preliminary application fee, as set forth in the municipal fee schedule, may bring a design before the board for preliminary review. If the applicant wishes to proceed with the project, he or she must then file an application and pay a regular application fee. The comments of the architectural review board members during a preliminary review shall not be binding on their formal recommendation.

      (4)   The design is functional, allowing for ease and safety of pedestrian and bicycle traffic and providing for elements that support the building's necessary operations (e.g. convenient vehicle access to property and utilities, appropriate arrangement and amount of open space and integrated signage, if applicable, etc.).

      (1)   Promote the internal integrity of the design of the project;

      (2)   Assure compatibility of the proposed project's design with its site and surroundings;

      (3)   Minimize the environmental effects of the proposed project; provided, however, that the architectural review board's sole responsibility with respect to the storage of hazardous materials is to require compliance with Title 17 (Hazardous Materials Storage).

   (g)   Phased Projects and Enforcement of Approval Conditions

   An application for a phased project may be submitted and a specific development schedule may be considered and approved. In no event, however, shall such a development schedule exceed five years from the original date of approval. Approved project plans and conditions of approval imposed through the architectural review process shall be enforceable as approved unless the application is revised or withdrawn in accordance with this title.

   (h)   Architectural Review Approval Prior to Demolition

   No building demolition, except for tenant improvements or where necessary for health and safety purposes (as determined by the director), shall be permitted on any site requiring architectural review approval, until such architectural review approval is granted by the director, including review of subsequent conditions by the architectural review board, where required.
