How to Use This Reference
This page consolidates the key code provisions from USDA/FNS, FDA Food Code, IBC, IMC, IPC, NFPA 96, and NFPA 101 that directly affect K-12 school kitchen design. Specific section numbers and dimensional thresholds are provided for direct reference during design development and plan review.
Note: Always verify against the edition adopted by your jurisdiction. Most states operate under the 2017 FDA Food Code; only 7 states have adopted the 2022 edition as of late 2024. California uses its own CalCode.

| Kitchen / food prep | Group E (accessory) or B | Accessory to E if <10% of building area |
| Cafeteria (<50 occupants) | Group E (accessory) | Part of educational occupancy |

| Function |
Load Factor (sf/person) |
Basis |
| Educational classroom | 20 | Net area |
| Assembly with tables (cafeteria) | 15 | Net area |

| Storage (dry, refrigerated) | 300 | Gross area |
Egress Requirements (IBC Chapter 10 / NFPA 101)
| Requirement |
Dimension |
| Corridor width (educational) | 72″ (6 ft) minimum |
| Aisle width | 30″ minimum |
| Door clear width | 32″ (most doors require 36″ nominal) |
| Dead-end corridor (unsprinklered) | 20 ft maximum |
| Dead-end corridor (sprinklered) | 50 ft maximum |
| Exit access travel distance (unsprinklered) | 150 ft |
| Exit access travel distance (sprinklered) | 200 ft |

IMC Chapter 5: Kitchen Exhaust
Type I hoods are required over equipment producing grease-laden vapors (fryers, grills, broilers, ovens). Type II hoods over equipment producing heat, steam, or moisture only (dishwashers, steamers). Makeup air is required when exhaust exceeds 400 CFM (IMC 505.4).
| Equipment Duty |
Wall Canopy (CFM/lin ft) |
Island Canopy (CFM/lin ft) |
Backshelf/Proximity (CFM/lin ft) |
| Light (ovens, steamers) | 200 | 250 | 150 |
| Medium (convection ovens, kettles, tilting skillets) | 300 | 300 | 200 |
| Heavy (fryers, griddles, ranges, salamanders) | 400 | 400 | 250 |
| Extra-heavy (char-broilers, wok ranges, solid-fuel) | 550 | 550 | N/A |
Critical Note
The highest duty-rated appliance under a hood determines the exhaust rate for the entire hood. A single char-broiler under a wall canopy with three other light-duty appliances means the entire hood operates at 550 CFM/linear foot.
IPC: Grease Interceptors & Plumbing
Grease interceptors are required for all establishments where grease may enter drainage (IPC). Key specifications: hydromechanical interceptors must be within 30″ vertical distance from fixture outlet and 60″ developed length. Emergency floor drain required downstream of grease interceptor. Backflow prevention per Section 608 — RPZ (ASSE 1013) for high hazard, DCVA (ASSE 1015) for low hazard.
Section 3
NFPA 96: Hood Systems & Fire Suppression
Hood Requirements
| Requirement |
Type I Hood |
Type II Hood |
| Purpose | Grease-producing equipment | Heat/moisture-producing equipment |
| Fire suppression (UL 300) | Yes — required | No |
| Grease filters (baffle-type) | Yes — required | No |
| Overhang beyond equipment | 6″ minimum on all open sides | Per manufacturer |
| Max height above cooking surface | 48″ (wall canopy) | Per manufacturer |
| Construction | Steel min 0.043″ (18 ga) or SS min 0.037″ | Similar |
Exhaust Duct Requirements
| Specification |
Value |
| Material | Carbon steel ≥0.060″ (16 ga) or SS ≥0.048″ (18 ga) |
| Joints/seams | Continuous external liquid-tight weld |
| Clearance from combustibles | 18″ minimum (0″ with noncombustible + insulation) |
| Slope — horizontal runs ≤75 ft | 2% minimum (~¼″/ft) |
| Slope — horizontal runs >75 ft | 8% minimum (~1″/ft) |
| Cleanout access | Every direction change + 12 ft max intervals |
Fire Suppression System
All Type I hoods require a UL 300 listed fire suppression system with automatic activation via fusible links AND manual pull station. System must provide automatic gas and electrical shutoff upon activation. A K-class fire extinguisher is required within 30 feet travel distance of cooking equipment. Semiannual inspection by certified technician is mandatory.
Hood Cleaning Schedule (NFPA 96)
| Cooking Volume |
Interval |
Examples |
| High volume | Every 3 months | 24-hour kitchens, char-broiling, wok cooking |
| Moderate volume | Every 6 months | Most school kitchens |
| Low volume | Every 12 months | Churches, seasonal kitchens |
Section 4
Plan Review: Required Submissions
A typical school kitchen plan review submission includes the following documents, each reviewed by different authorities:
| Document |
Reviewed By |
| Floor plan with equipment layout | Health dept, building dept, fire marshal |
| Equipment schedule with NSF certification | Health dept |
| Finish schedule (floors, walls, ceilings) | Health dept, building dept |
| Plumbing plan (fixtures, grease traps, backflow) | Building dept (plumbing), health dept |
| Mechanical plan (hood system, makeup air, HVAC) | Building dept (mechanical), fire marshal |
| Electrical plan | Building dept (electrical) |
| Fire suppression plan | Fire marshal |
| Accessibility compliance documentation | Building dept |
| Menu and anticipated meal volume | Health dept |
Re-Review Triggers
| Trigger |
Authorities Requiring Re-Review |
| Kitchen renovation above dollar threshold | All four (health, fire, building, ADA) |
| Change of occupancy use | Building dept, fire marshal |
| New grease-producing cooking equipment | Health dept, fire marshal |
| Hood or fire suppression modification | Fire marshal, building dept (mechanical) |
| Structural changes (walls, doors, floor) | Building dept, potentially all |
| ADA complaint | DOJ, building dept |
Conflict Resolution Principle
When code requirements from different authorities conflict, the most stringent requirement prevails unless a variance or alternative compliance method is approved in writing by the relevant Authority Having Jurisdiction (AHJ). Common conflicts include: fire egress vs. ventilation (self-closing doors with hold-open devices), ADA clearance vs. equipment density (designated accessible workstations), and floor materials (quarry tile or textured epoxy to satisfy both cleanability and slip resistance).
Section 5
State Variations
States adopt the FDA Food Code with modifications. Key variations to verify during design:
| State |
Code Basis |
Notable Differences |
| California |
CalCode (independent state legislation) |
Not based on FDA Food Code; separate California Building Code with seismic and energy requirements (CEC Section 10.3 for kitchen ventilation) |
| Texas |
FDA Food Code 2017 with amendments |
Specific sections not adopted: 3-202.13, 6-101.11(B), and all of Chapter 8; modified floor surface requirements |
| New York |
Based on FDA 1997 with significant modifications |
More stringent cold holding (41°F); specific drainboard requirements; NYC Article 81 has additional equipment and facility requirements |
| Most states |
FDA Food Code 2017 |
Majority adoption; always check state-specific amendments |
Always confirm the specific edition adopted by your jurisdiction before finalizing design. Contact the local health department and building department early in the design process to confirm which code versions and local amendments apply.
