APPLICATION This policy applies to all permit applicants submitting non-electronic fire sprinkler (and similar) plans to the Fresno Fire Department (FFD or Department) for review and approval within the City of Fresno and contract service areas. OPERATIONAL POLICY Based upon the need for uniformity in application across the Department’s diverse service delivery area, and after careful deliberation, the Department has determined the following: 1. Automatic fire sprinkler (and similar) system plans shall be drawn with care by a trained person meeting the requirements found within the applicable law, code, ordinance, or standard. 2. Plans shall be drawn on a minimum of twenty-four inch by thirty-six-inch (24” X 36”) paper and shall be drawn to an indicated scale of not less than one-eighth (1/8”) inch = one (1’) foot. Buildings over fifty thousand (50,000) square feet (sq. ft.) shall have an overview plan showing the entire building, including all fire protection features. 3. An area no less than four (4”) inch x six (6”) inch, located in the bottom right- hand corner of each plan sheet, shall be left free of any text, mark, etc., to facilitate the marking of plans by Department staff. 4. Drawings shall be organized based upon the United States Department of Energy, Fundamentals Handbook for Engineering Symbology, Prints, and Drawings (Vols. 1 & 2) (1993 edition).

Drawing line weights, match lines (where used) and legibility (including printed pages) shall be in accordance with either the United States Department of Energy, Fundamentals Handbook for Engineering Symbology, Prints, and Drawings (Vols. 1 & 2) (1993 edition), or the latest American Institute of Architects design guidelines. 6. All fire sprinkler symbols shall be in accordance with National Fire Protection Association (NFPA) 170, Standard for Fire Safety and Emergency Symbols, Chapter 7, where a symbol is provided. For each type of fire sprinkler to be installed, a different symbol shall be used. 7. In addition to all of the information that is required in this document, plans shall also include all of the information noted in NFPA 13, Automatic Sprinkler Systems (2022 ed.) §28.1.3 et. al. As noted in the referenced standard, this information constitutes the minimum amount of information required to be submitted to the authority having jurisdiction. 8. Each of the following items shall be included on either a single page of an automatic fire sprinkler system plan or submittal booklet. These items will be verified at the counter and plans will be rejected when not present: A. A detailed scope of work for the project including a description sufficient to clearly indicate the location, nature and extent of the work. A scope of work indicating “installation of a fire sprinkler system”, or similar non-descript scoping is inadequate, and plans will be rejected without review. B. Name of owner, occupant, or contracted construction firm. C. Location of the project, including the City of Fresno (City) officially assigned address and the City building permit number. D.
