If it is a building code issue, you may file a request for modification. Please refer to the Request for Modification (Mod.00) form for reference. In approving such a request, the Department needs to determine that the slight modification is reasonably equivalent to the ordinance requirement involved, that a special individual reason makes the strict letter of the ordinance impractical, and that the slight modification is in conformity with the spirit and purpose of the Code involved.
If the request is denied by the Department, it may be appealed to the Board of Building and Safety Commissioners.
If it is a Planning Code issue, this Department can only review and act on items stipulated in Section 12.26, specifically, yard variances not exceeding 20% of the required yard and parking facility design as published in Sec. 12.21A5. (Reprint from Planning Code Section 12.26). All other request for changes from the Planning Code shall be filed with the Planning Department.
