Permits and Inspections
The Wentzville Fire Protection District utilizes fire prevention codes to ensure the proper installation and maintenance of fire protection and life safety systems, identify and mitigate potential fire and life safety hazards, and ensure buildings are accessible to responding fire and EMS crews in an emergency. The fire district is enforcing the 2021 International Fire, Building, Existing Building and Mechanical Codes, including the 2019 editions of NFPA 13-Installation of Fire Sprinklers and NFPA 72-Fire Alarm and Signaling Code. These codes have been adopted with amendments that can be found within Ordinance 221
Construction Permits
All commercial and multi-family new construction require a permit before construction begins. This includes, but is not limited to, site plans, new buildings, alterations and additions to existing buildings, underground fire sprinkler supply mains, fire sprinkler systems, and fire alarm systems. Drawings must be sealed by a Missouri licensed design professional. Fire alarm drawings completed by a NICET level IV designer will be accepted.

Knox Box
A Knox box is required on your building if your building has a fire alarm or sprinkler system. A minimum of a 4400 series box is required. It should be mounted near the front entry approximately 5 feet above grade on the building unless otherwise authorized or directed by the fire code official.
Wentzville FPD is the default agency that should be selected when purchasing a Knox Box, unless the fire code official specified otherwise on your returned construction drawings. If ‘mutual aid’ is specified, select ‘St Charles Co Fire Prot Assn/Emerg Svc’ as the local fire department/agency when ordering.
