Fire Safety Requirements Analyzer
Analyze fire and life safety requirements for a proposed building design, including sprinkler requirements, fire-resistance ratings, egress systems, and fire separation requirements. This prompt helps architects identify fire safety code requirements early in design to avoid costly redesigns during plan review.
This prompt analyzes fire and life safety requirements for a building based on its occupancy classification, construction type, story count, area, and sprinkler status, producing a structured analysis covering sprinkler trigger thresholds, required fire-resistance ratings for structural elements and assemblies, egress travel distances and exit counts, fire separation requirements, and fire department access considerations. The output also identifies items requiring clarification with the local fire code official or coordination with a fire protection engineer before design decisions are locked in. It is for licensed architects in the schematic and design development phases who need to surface life safety code requirements early enough to influence major design moves.

Constraints
Verify all code references and calculations independently. This does not replace licensed professional review.
Fire protection engineering — including sprinkler system design, fire alarm system design, and egress analysis — requires a licensed fire protection engineer in most jurisdictions.
Local fire code amendments and fire department interpretive policies can significantly affect requirements — always coordinate with the local fire code official.
Life safety is the highest priority code compliance domain — never proceed with a design where fire safety compliance is uncertain without engineering consultation.

The prompt
You are a licensed architect with expertise in fire and life safety code compliance, working in collaboration with fire protection engineers on complex projects. Analyze the fire and life safety requirements for the following project: Project information: - Building use / occupancy: [OCCUPANCY — e.g., B Office, A-2 Restaurant, R-2 Multi-family] - Construction type: [CONSTRUCTION_TYPE — e.g., Type V-B, Type II-A] - Number of stories: [STORIES] - Building height: [HEIGHT] - Gross floor area per story: [FLOOR_AREA] - Total gross building area: [TOTAL_AREA] - Automatic fire sprinkler system: [SPRINKLERS — yes / no / proposed] - Applicable code: [BUILDING_CODE — e.g., IBC 2021, NFPA 101 2021] - Jurisdiction: [JURISDICTION] Specific design elements or conditions: [DESCRIBE ANY SPECIFIC FIRE SAFETY QUESTIONS OR DESIGN ELEMENTS] Provide a fire and life safety analysis covering: ## Sprinkler Requirements Is automatic fire suppression required? What standard applies (NFPA 13, 13R, 13D)? What are the sprinkler system triggers for this occupancy, construction type, and area? ## Fire-Resistance Ratings Required ratings for structural elements, floor-ceiling assemblies, roof construction, and fire walls/barriers based on construction type and occupancy. ## Egress Requirements Minimum number of exits, maximum travel distance, exit corridor width, exit discharge, and occupant load calculation. ## Fire Separation Requirements Required separations between occupancies, tenant spaces, or hazardous areas. Shaft and opening protection requirements. ## Fire Department Access and Features Fire department vehicle access, FDC location requirements, fire alarm system requirements. ## Key Compliance Questions Items that require clarification with the fire code official or fire protection engineer before finalizing design. Note: Fire safety requirements must be confirmed with a licensed fire protection engineer and the local fire code official.

How to use this prompt
1
1. Confirm occupancy classification and construction type before running the analysis — these two parameters drive the majority of fire safety requirements.
2
2. Use the sprinkler requirements section early in design, as a decision to sprinkler (or not) significantly affects allowable building area and can change the required construction type.
3
3. Share the egress analysis with your architect of record team for verification before permit submission.
Customization tips
Add 'The building includes an atrium / covered mall / high-rise conditions (above 75 feet)' to trigger analysis of the special fire safety requirements for these building types.
For mixed-occupancy buildings, add 'The building contains [list occupancies] — analyze both the separated occupancy and nonseparated occupancy approaches and recommend which is more favorable.'
Append 'The project is a [historic building / existing building alteration] — analyze the applicable exceptions and alternative compliance methods.'
Sample output
FIRE SAFETY REQUIREMENTS ANALYSIS — 6-Story Mixed-Use Development
PROJECT: 6-story mixed-use (ground floor commercial + 5 residential floors)
LOCATION: Portland, Oregon
REVIEW DATE: March 23, 2026
REVIEW STATUS: Schematic Design Phase
FIRE PROTECTION SYSTEM:
A building of this height and occupancy type requires a fully automatic fire sprinkler system throughout all occupancies, common areas, and mechanical spaces. Sprinkler protection is a fundamental design assumption that affects required fire ratings, corridor configurations, and egress travel distances. The fire protection engineer should be engaged during schematic design — not at construction documents — because sprinkler system design choices affect structural layout, ceiling construction, and mechanical space allocation.
FIRE ALARM AND DETECTION:
A building-wide addressable fire alarm system is required. The system must include automatic sprinkler flow alarms, smoke detection in common corridors, stairways, elevator lobbies, and mechanical rooms. Residential units require smoke alarms per applicable residential code requirements. Carbon monoxide detection is also required in residential units with attached garages or fuel-burning appliances.
OCCUPANCY SEPARATION:
The horizontal separation between the ground floor commercial occupancy and the residential floors above must be a fire-rated assembly. The specific rating is determined by the occupancy types present, the building construction type, and the sprinkler system design. Work with the structural and fire protection engineers to confirm the required rating and establish a compliant structural deck and fire-resistive assembly design.
STAIR ENCLOSURES:
All required exit stairs must be enclosed in fire-rated shaft construction. Stair enclosure doors must be fire-rated assemblies with self-closing devices. Coordinate stair door hardware selection with the life safety requirements — electromagnetic hold-open devices must release automatically on alarm activation.
STANDPIPE SYSTEM:
A standpipe system is required in buildings of this height. Standpipe hose connections must be provided at each floor level within the stair enclosures. Coordinate with the fire protection engineer for standpipe riser locations, which affect floor plan layout.
ELEVATOR LOBBIES:
At this building height, smoke protection requirements at elevator lobbies may apply. Confirm with the code consultant whether pressurized elevator lobbies or smoke barriers are required at each residential floor.
EMERGENCY RESPONDER ACCESS:
Fire apparatus access lanes and fire department connections for the sprinkler and standpipe systems must be coordinated with the civil engineer and the Portland Fire Bureau during schematic design.
DISCLAIMER: Fire and life safety code compliance is complex and jurisdiction-specific. This analysis is a preliminary framework. Engage a licensed fire protection engineer and code consultant for project-specific analysis.

Frequently asked questions
For any project with complex occupancies, high occupant loads, high-rise conditions, atria or unusual vertical connections, hazardous materials, or performance-based fire safety alternatives, engage a fire protection engineer early in schematic design. Their input on sprinkler system design can affect ceiling heights, mechanical coordination, and structural decisions — late engagement is expensive. For straightforward low-rise commercial projects, the architect typically handles fire safety compliance directly, but consult the local fire official on any uncertain items.
A fire wall is a structural assembly that compartmentalizes a building into separate fire areas — it has the highest fire resistance rating requirements and typically requires post-and-beam or equal construction to ensure stability if one side collapses. A fire barrier is an interior wall that provides fire resistance between occupancies or hazardous areas but does not create separate buildings. The distinction matters significantly for large-footprint buildings where fire area limitations would otherwise require a more costly construction type.
