Complete Guide: Where to Post Evacuation Maps in Your Building
If a facility uses or is required to post evacuation maps, their locations should help occupants understand the reviewed emergency procedures. OSHA's emergency-preparedness resources address plans, procedures, and employee communication, but federal OSHA does not prescribe a universal map count or placement list. This guide separates that federal context from adopted-code and local-authority questions.
Federal OSHA: EAP Duties vs. Posted Maps
When another covered OSHA standard requires an EAP, 29 CFR 1910.38 requires evacuation procedures and exit-route assignments. For a covered employer, more than 10 employees generally means the plan is written; 10 or fewer may communicate it orally. The section does not universally require a posted diagram or prescribe its height, size, symbols, or locations. A verified map can support employee communication, but it does not replace the EAP or training. Learn more on our OSHA evacuation map requirements page. If you are assessing an absent or outdated map rather than deciding where to place one, see the qualified guide to possible evacuation-map consequences, then prepare a map draft for review.
California Evacuation Map Posting Requirements
California applicability depends on the Cal/OSHA EAP duty, adopted California Fire Code edition, occupancy and use, local amendments, permits, and licensing rules. Section 3220 should not be treated as a universal posted-map mandate. Verify whether the current code requires a diagram, where it belongs, and what it shows with the local authority. For further context, visit our California evacuation map guidance page.
Seismic planning, language access, accessibility, and conspicuous-placement provisions may apply to particular facilities or programs, but they are not a single statewide content checklist for every map. Confirm the exact provision, edition, enforcement agency, and facility facts before relying on a generic list.
Posting Location Best Practices
If maps are used, decision points such as corridor intersections, stairwell approaches, and elevator lobbies are reasonable locations to evaluate. There is no universal federal 100-foot spacing rule. Use a site walk, occupant needs, visibility, and any adopted placement criteria to decide where a map aids orientation.
A heads-up orientationโwhere the top of the map corresponds to the viewer's facing directionโmay improve comprehension, but each posted copy must be verified for its actual viewing position. Our AI map generator creates a draft with orientation markers; a reviewer must adjust and confirm each copy. For design principles, see our evacuation map design guide.
Special Posting Requirements by Building Type
Hotels, schools, healthcare facilities, warehouses, and licensed programs may be subject to occupancy-specific requirements where an NFPA, IBC, fire, lodging, education, or healthcare provision has been adopted. Requirements vary by edition, building features, license, and jurisdiction. Confirm whether guest rooms, classrooms, treatment areas, or other spaces need maps and what those maps show. See our hotel evacuation map guide for planning context.
Warehouses, manufacturing facilities, and construction sites should coordinate any map locations with changing routes, operational hazards, the emergency plan, and applicable code or permit conditions. Aisle ends, loading docks, work areas, or temporary site offices are candidatesโnot universal mandates. For egress route planning, see our dedicated guide.
Accessibility Review for Posted Evacuation Maps
Accessibility standards may affect mounting, reach, tactile signs, and emergency communication, but a generic 48-inch rule does not establish a universal evacuation-map height. Verify which standard and sign type apply, whether tactile or visual information is required, and how the emergency plan addresses people who may need assistance. Mark areas of assistance only when they are verified and applicable.
Maintaining Posted Evacuation Maps
Keep any posted map consistent with the actual building and reviewed procedures. Common update triggers include renovations, tenant buildouts, equipment relocation, exit-route changes, new assembly points, and occupancy changes. For a covered EAP, 29 CFR 1910.38 requires employee review when the plan is developed or changed and when responsibilities change; follow any separate map-review cadence set by an adopted code, license, permit, insurer, or facility policy. Use our fire escape plan maker to regenerate a draft when conditions change.
