A life safety plan is the drawing in a permit set that shows how the building’s egress and fire protection meet the code: the occupancy classification, the occupant load of every room and floor, the exits and the width they provide, travel distance, common path of travel, dead ends, the fire-resistance ratings of walls and floors, and the sprinkler and fire alarm coverage that those numbers depend on. Plan examiners read it first, because every other fire protection drawing in the set has to agree with it.
Most jurisdictions do not call the sheet a “life safety plan” in the code itself. The International Building Code requires the information, and designers put it on one or two sheets so the reviewer can check the egress math without hunting through the architectural set. This article explains what a life safety plan contains, where the requirement comes from, how it differs from the documents it is confused with, and when a project needs one.
At a Glance: Life Safety Plan
- Definition: a code analysis drawing that documents occupancy, occupant load, egress and fire protection for a building or tenant space.
- Governing code and section: 2021 International Building Code (IBC) Section 107.2.3, which requires construction documents to show all portions of the means of egress and to designate the number of occupants on every floor and in every room, except in Groups R-2, R-3 and I-1. The egress rules it documents are IBC Chapter 10 and, in Maryland and Delaware, NFPA 101 Chapter 7.
- Who prepares it: the architect of record or a fire protection engineer, sealed by the design professional responsible for the code analysis.
- When it is required: new buildings, additions, changes of occupancy, tenant fit-outs that change the layout or occupant load, and many alterations under the existing building codes.
- Typical output: one or two sheets at the front of the architectural set: a code summary, a floor plan per level with egress callouts, and an occupant load table.
- Often confused with: the fire safety and evacuation plan, which is an operations document for the people in the building, not a design drawing.
What a Life Safety Plan Includes
A life safety plan answers a fixed set of questions for every floor. The table lists the items a plan examiner expects, what each one shows and where the requirement sits in the 2021 IBC. Jurisdictions on other codes read the same items from their own sections; the jurisdiction table below lists them.
| Component | What the plan shows | 2021 IBC basis |
|---|---|---|
| Code summary | Applicable code and edition, occupancy group, construction type, sprinkler status, building height and area, and whether the project is new work or an alteration under the existing building code | Section 107.2.1; Chapters 3, 5 and 6 |
| Occupant load | The occupant load of each room and each floor, with the area and the factor used, and the posted load for assembly spaces | Section 1004, Table 1004.5, Section 1004.9 |
| Egress capacity | Required and provided width of each door, corridor and stair, at 0.2 inch per occupant for level components and 0.3 inch per occupant for stairs, with the sprinklered reductions where they apply | Section 1005.3 |
| Number and arrangement of exits | Exits and exit access doorways from each space and floor, and the separation between them, measured against one half of the room or floor diagonal, or one third in a sprinklered building | Sections 1006, 1007.1.1 |
| Travel distance, common path, dead ends | The longest exit access travel distance on each floor, the longest common path of egress travel, and any dead-end corridor, each drawn and dimensioned | Sections 1017, 1006.2.1, 1020.5 |
| Fire-resistance ratings | Rated corridors, shafts, exit enclosures, fire barriers, fire walls and horizontal assemblies, with their ratings and the opening protectives in them | Chapter 7, Sections 1020 and 1023 |
| Fire protection systems | Where sprinklers, standpipes and fire alarm are provided, because the egress numbers often depend on them | Chapter 9 |
| Accessible egress and signage | Accessible means of egress, areas of refuge where required, exit signs and emergency lighting | Sections 1009, 1013, 1008 |
The drawing works as a single page because each number depends on the one before it. Occupant load sets the required egress width and the number of exits. The number of exits sets the separation test. The sprinkler status changes the egress factors, the travel distance limit and the dead-end limit.
When a reviewer finds an error in a life safety plan, it is usually one of these dependencies broken: a sprinklered travel distance claimed in a building that is not sprinklered, or an occupant load that was never carried into the stair width.

Where the Code Requires a Life Safety Plan
The requirement is a documentation rule, not a chapter of its own. In the 2021 IBC, Section 107.2.1 requires construction documents detailed enough to show that the work conforms to the code, and Section 107.2.3 adds the egress-specific content: every portion of the means of egress, including the exit discharge to the public way, and the number of occupants to be accommodated on every floor and in all rooms and spaces, except in Groups R-2, R-3 and I-1. A life safety plan is the industry’s standard way to satisfy that section.
The numbers on the plan come from IBC Chapter 10. Occupant load is calculated under Section 1004 using the floor area allowances in Table 1004.5, which for example gives 150 square feet gross per occupant for business areas and 15 square feet net for unconcentrated assembly. Egress width follows Section 1005.3. The exit count, separation and travel limits follow Sections 1006, 1007 and 1017.
In Maryland and Delaware the same analysis is also measured against NFPA 101, the Life Safety Code, whose Chapter 7 carries the parallel occupant load and capacity rules, and both codes have to be satisfied.
Each jurisdiction DGA works in asks for the drawing in its own words. The table shows where the requirement sits and what the reviewer calls it.
| Jurisdiction | Code and edition | Where the requirement sits | Reviewer |
|---|---|---|---|
| New York City | 2022 NYC Building Code; Administrative Code Chapter 28 | Construction documents under Administrative Code Section 28-104.7; egress and occupant load drawings are standard required items in DOB NOW, and the Schedule of Occupancy on the PW1 lists maximum persons per floor. NYC uses its own occupant load table (Building Code Section 1004) with factors that differ from the IBC, including 100 square feet gross for business areas. | Department of Buildings; FDNY for fire alarm and Place of Assembly |
| New York State (outside NYC) | 2025 Uniform Code, based on the 2024 I-Codes | 2024 IBC Section 107.2.3 as adopted; occupant load under Section 1004 of the Building and Fire Codes of New York State | Local code enforcement official |
| New Jersey | Uniform Construction Code, 2024 I-Codes (New Jersey editions), effective August 17, 2026 | Construction document requirements in N.J.A.C. 5:23-2.15, with the building subcode’s Section 107.2.3; the fire protection subcode official reviews the egress and fire protection sheets | Municipal construction official and fire protection subcode official |

Life Safety Plan vs Fire Safety and Evacuation Plan
The two documents share a name and almost nothing else. A life safety plan is a sealed design drawing reviewed at permit; it proves the building can hold its occupants and get them out. A fire safety and evacuation plan is an operations document the fire code requires of the owner after the building opens; it tells the people inside what to do. New York City adds a third variant, the Fire Safety and Emergency Action Plan required by the NYC Fire Code for office buildings and other listed occupancies, which is filed with FDNY and kept current by a fire safety director.
Figure 2: Two Plans, Two Jobs
- Prepared by the architect or fire protection engineer, sealed
- Reviewed at permit by the building official
- Shows occupant load, exits, widths, travel distance, ratings, systems
- Basis: IBC Section 107.2.3 and Chapter 10; NFPA 101 in MD and DE
- Changes when the layout, use or systems change
- Prepared by the owner or manager, often with a consultant
- Required by the fire code for listed occupancies; kept on site
- Covers evacuation routes, staff duties, drills, alarm response
- Basis: IFC Chapter 4; NYC Fire Code Chapter 4 and FDNY rules
- Updated annually and when staff or procedures change
Two other terms sit nearby. A life safety evaluation is a performance study of a large assembly building under NFPA 101 Chapter 12, not a drawing. A fire protection plan or fire protection narrative is a written report that some reviewers, including the Delaware State Fire Marshal and federal agencies, ask for alongside the drawings; it describes the systems and the design basis in prose. A life safety plan can reference either, but it does not replace them.
When a Project Needs a Life Safety Plan
A life safety plan is required whenever a permit application has to show that egress complies, which in practice means almost every commercial project. New buildings and additions always need one. A change of occupancy needs one because the occupant load factor, the exit count and the travel limits change with the use; DGA’s article on when a change of occupancy triggers fire protection upgrades covers those triggers. A tenant fit-out needs one when walls move, the occupant load changes or an exit is affected, even inside a building whose base life safety plan is on file.
Three situations catch owners out. A conference room added to an office floor can raise the floor’s occupant load past 49 and require a second exit from the suite. A retail stockroom converted to sales floor changes the factor from 300 to 60 square feet per occupant and can overload the existing doors. And a proposed alternative to a prescriptive rule, such as a longer travel distance in a sprinklered warehouse, has to be documented on the life safety plan and approved through the jurisdiction’s variance path; DGA’s guide to IBC 104.11 alternative methods and the NYC CCD1 explains how.
Common Misconceptions
“The architect’s code sheet is the same thing.” Sometimes. A code summary that lists occupancy and construction type without per-room occupant loads, exit widths and travel distances does not satisfy Section 107.2.3, and reviewers in New York City, New Jersey and Maryland routinely object to it. The life safety plan is the code sheet with the egress math drawn on the floor plan.
“A sprinklered building does not need the egress analysis.” Sprinklers change the numbers; they do not remove them. The 0.2 and 0.15 inch per occupant factors, the one-third diagonal, the longer travel distances and the 50-foot dead end are all conditioned on the sprinkler system, so the plan has to show the system to claim them.
“Once the base building has one, tenants are covered.” The base building plan proves the shell and core. Each tenant layout changes room loads and common paths, so each fit-out permit needs its own sheet for the space, tied back to the floor totals.
Who Needs to Act
| Who | One action |
|---|---|
| Owner | Keep the approved life safety plan with the building records and hand it to every tenant’s design team before they draw. |
| Tenant | Give the architect the real headcount and furniture plan; the occupant load the reviewer uses comes from area, but a higher actual count has to be designed for. |
| Architect | Put the per-room occupant loads, widths and distances on the plan, not only in a summary table. |
| General contractor | Treat the life safety plan as the controlling sheet when a field change moves a wall or a door. |
| Insurer or lender | Ask for the approved life safety plan in due diligence; it is the fastest check that the occupancy matches the certificate of occupancy. |
Key Takeaway: A life safety plan is the one drawing that proves the egress math: occupancy, occupant load per room and floor, exit count and separation, required and provided width, travel distance, dead ends, ratings and the systems those numbers rely on. The IBC requires the content in Section 107.2.3; the sheet is how designers deliver it, and it is the first thing a plan examiner reads.
Frequently Asked Questions
Is a life safety plan required by code?
Yes. The 2021 IBC requires construction documents to show every portion of the means of egress and to designate the number of occupants on every floor and in every room outside Groups R-2, R-3 and I-1 (Section 107.2.3). The life safety plan is the standard way to meet that requirement, and jurisdictions on NFPA 101 ask for the same analysis.
Who can prepare a life safety plan?
Conditional: the architect of record usually prepares it, and a fire protection engineer prepares or reviews it on complex projects, high-rises, assembly buildings and alternative-method cases. The sheet is sealed by the licensed design professional responsible for the code analysis.
Does a tenant fit-out need its own life safety plan?
Yes, when the layout, use or occupant load changes. The base building plan proves the shell and core; the fit-out plan proves the suite and ties its occupant load back to the floor totals and the exits.
Is a life safety plan the same as a fire safety or evacuation plan?
No. A life safety plan is a sealed design drawing reviewed at permit. A fire safety and evacuation plan is an operations document the fire code requires of the owner after occupancy, and in New York City the Fire Safety and Emergency Action Plan is filed with FDNY.
What does a reviewer check first on a life safety plan?
The occupant load per room and floor, because the exit count, egress width and separation all follow from it. The second check is whether the sprinkler status shown on the plan matches the building, since the reduced egress factors and longer travel distances depend on it.
