This document is a guide for building owners, business owners, general contractors and registered design professionals in determining the level of plans and construction documents required for submittal during the permit application process as well as the design/build process.  Contained within are common requirements for common conditions.  This guide cannot possibly address all buildings, processes or situations regulated by code that may be present or proposed in specific situations.

The Fire Code Official may require additional plans and construction documents as necessary.  Consultation with a Registered Design Professional and the Fire Code Official early in the planning process is strongly recommended, if not a necessity.

Level I:  Existing Building Change of Use/Occupancy – Simple

This section is intended to be used where no work is proposed or required to achieve compliance with code, given the proposed use and occupancy type.  (For example:  A new small business office opening in an existing tenant space where the new business will use the existing space as is.)

  2. Generally, light cosmetic changes such as paint and flooring are acceptable without plans.

Level III Plans shall include all items listed in Level II requirements and in addition:

  1. Structural plans prepared, signed and sealed by a Professional Engineer.
  2. Site Plan, prepared, signed and sealed by a Registered Design Professional.

Site Plan Requirements

Site plans shall indicate:

  1. Lot lines and dimensions
  2. Adjacent lots and buildings
  3. Existing and proposed buildings and dimensions
  4. Roads and drives, including material and dimensions
  5. Parking areas and dimensions
  6. Existing and proposed fire hydrants

Fire Mains, Fire Sprinklers, Fire Suppression & Detection Systems

Plans/shop drawings are required for all fire suppression and detection systems and must be prepared, signed and sealed by a Professional Engineer.  Detail documents, including plans and specifications must be submitted and approved prior to installation but need not be submitted upon Application For Permit.

Kitchen Hood Exhaust Systems

Plans/shop drawings are required for all kitchen hood exhaust systems.  Detail documents, including plans and specifications must be submitted and approved prior to installation but need not be submitted upon Application For Permit.  Below are some common inquiries that may assist with design:

Horn Strobe:                                        Required
Exhaust Fan Shut Down:                     No, must stay active
Make Up Air Shut Down:                    Yes, must shut down
Appliance Electric Shut Off:                Required
Appliance Gas Shut Off:                      Required
Inspections:                                         Light or smoke test for welds/connections, fire wrap inspection.

Residential type ranges in commercial occupancies, such as in a break room do not require a hood exhaust system, unless food is prepared for commercial purposes.  However, a fire suppression system is required.  We do not recommend products,  however, an example of a generally acceptable pre-manufactured system can be found at .

Existing Buildings & Critical/High-Risk Occupancy Groups

In regard to existing buildings, Level II plan requirements apply to all of the following occupancy groups where a change of use/occupancy is proposed or where conditions necessitate a Registered Design Professional review and determine requirements.  Level II plan requirements apply regardless of whether construction is taking place.

  1. Assembly
  2. Educational
  3. Institutional
  4. High Hazard

Registered Design Professional Requirements

Plans and construction documents must be prepared, signed and sealed by a Registered Design Professional, including Architects and Engineers.  Certain construction documents must be signed and sealed by only a Professional Engineer.  This section indicates when and Engineer’s seal is required.

Structural Design & Plans:      Professional Engineer
Fire Suppression Systems:      Professional Engineer

Submission of Plans

All plans and construction documents must be submitted electronically, in .PDF format.  These can be uploaded during the Application for Permit at or submitted by email to the Fire Marshal.  If by email, large files should first be uploaded to a 3rd party service, such as DropBox.
