Most often, a code modification is a request to modify a code provision where your project's design or construction does not meet the letter of the Statewide Fire Prevention Code, Chapter 62 of the Code of Fairfax County, or fire protection related provisions of the Public Facilities Manual. "Code mod" requests must propose changes to a code provision that provide an equivalent level of fire and life safety. The county cannot outright waice code provisions. The Fire Code Modification record is required by the Office of the Fire marshal when the above provision is desired.
