Section 105.6.1 of the CFC, Automatic fire-extinguishing systems, is amended to read as follows:

105.6.1 Automatic fire-extinguishing systems. A construction permit is required for installation of or modification to an automatic fire-extinguishing system. Maintenance performed in accordance with this code is not considered a modification and does not require a permit. In buildings where a fully automatic sprinkler protection system exists, and where said buildings undergo remodeling and/or alterations or additions, the automatic sprinkler system shall be kept in good operable condition and be extended to include additions, area separation walls notwithstanding. In buildings where an automatic sprinkler system does not exist, and the floor area is increased twenty-five percent or more, throughout the life of the building, and the area exceeds ten thousand square feet, before or after the addition, an automatic sprinkler system shall be installed throughout the total building.
