1. As set forth in this Section, a particular addition or alteration to an existing structure or site may be approved by a staff approval or a design review exception, without submitting the matter to the Planning Commission for its approval. Such administrative approvals shall be limited in number as follows:

2. Staff Approval. If the Planning staff determines that a particular alteration to an existing structure or site is insignificant and in no way defeats the purposes and objectives of this Chapter, approval may be granted therefor without submitting the matter to the Planning Commission for its approval, notwithstanding any other provision of this Section or Chapter. Such administrative review may cover, but is not limited to, changes in window and door locations and sizes, addition of skylights, and minor changes of colors or materials for existing or proposed structures, and is in general limited to alterations which do not include the addition of square footage. Such determination by the Director of Planning and Building shall be indicated on the building permit for such alteration and in a memorandum to the appropriate building department address file.

3. Design Review Exceptions. For exterior alterations and additions which the Director of Planning and Building determines are minor and in no way defeat the purposes and objectives of this Chapter, subject to the following procedure, design review approval may be granted therefor without submitting the matter to the Planning Commission for its approval, notwithstanding any other provision of this Section or Chapter. Such review may cover, but is not limited to, additions of up to one hundred square feet in size, and those changes which do not qualify for review under the procedure listed in Subsection (B)(2) of this Section. In order for the design review exception to be granted, the Director of Planning and Building, the Planning Commission Chairman and the City Manager must first indicate their approval of the proposal. If any one of the aforementioned City representatives determines that an application is not minor in scope, the design review exception shall not be granted. Subject to submittal of additional required materials and fees, pursuant to Sections 20.04.080 and 20.04.090, the application shall be considered as a regular design review application at the next available meeting of the Planning Commission. If all of the aforementioned City representatives have indicated their approval, written notice of the design review exception shall be posted on the City Hall bulletin board and delivered or mailed to each owner of property within one hundred feet of the property for which such exception is to be granted. In lieu of written notice to property owners within one hundred feet of the project site, the applicant may provide the City with signatures of such property-owners on the project plans, indicating approval of the project. If all required signatures are provided, the Director of Planning and Building may grant the design review exception after posting of the written notice. If all required signatures from neighboring property owners are not provided, any interested person may appeal the design review exception by submitting written notice of such appeal to the Director of Planning and Building within ten calendar days of the posting and delivery or mailing, in which event the building permit shall be held in abeyance until approval is obtained from the Planning Commission, or from the City Council on further appeal. For purposes of filing an appeal, if the final day to appeal falls on a City Hall observed holiday or a day when City Hall is closed, the final day to appeal shall be extended to the next day City Hall is open for public business. The effective date of approval of the design review exception shall be indicated on the subject plans.
