The “Small Project” letter shall be submitted on the registered contractor’s company letterhead, and shall include the following information:    

• Project name, address, anticipated start and completion dates

• Project scope of work, number of sprinkler heads

• Statement indicating that the tenant finish, remodel or additions do not affect the hydraulic demand design or integrity of the existing fire protection system.  

Submittal of hydraulic calculations and equipment specification sheets for projects with less than 20 sprinkler heads for commercial projects, or less than six heads for residential, are at the discretion of the AHJ.  All installations require an AHJ rough-in and final inspection regardless of the number of heads altered or installed.  Contractors are required to call for inspections prior to work being covered.  This excludes minor repairs and maintenance issues associated with existing systems.

106.1 Submittals:  Construction documents and supporting data shall be submitted in two or more sets with each application for a permit and in such form and detail as required by the fire code official.  The construction documents shall be prepared by a registered design professional where required by the statues of the jurisdiction in which the project is to be constructed.  

Exception:  The fire code official is authorized to waive the submission of construction documents and supporting data not required to be prepared by a registered design professional if it is found that the nature of the work applied for is such that review of construction documents is not necessary to obtain compliance with this code.
