How to Propose a Historical Marker: Criteria, Application Steps, and What Comes After Approval

Proposing a historical marker is a formal, competitive process, but it follows a recognizable pattern across state programs: your subject must demonstrate genuine historical significance, you must document it with verifiable sources, and you must submit a complete application packet to a state or local historical commission by a set deadline. Programs run by the Pennsylvania Historical and Museum Commission, the Georgia Historical Society, the Kentucky Historical Society, and the Delaware Public Archives differ in their details, but they share the same essential architecture. Understanding that architecture before you begin can save months of research on a topic that was never eligible.

Understanding Historical Marker Eligibility Criteria

The most common reason strong-seeming proposals fail is the significance threshold. Pennsylvania's commission, adopting its criteria by resolution in September 2020, requires that the person, place, event, organization, or innovation to be marked "had a significant impact on its times, and has statewide and/or national, rather than local or regional, historical significance." Georgia's program similarly asks its review committee to weigh not only a marker topic's local impact but how the story fits into the larger historical narrative and the statewide marker program. In Virginia, topics of purely local interest are handled through community marker programs, while subjects of state or national significance go through the standard state approval process before the Board of Historic Resources.

Age matters too. The Georgia Historical Society considers markers for events only when the event took place at least twenty-five years before the application date, and buildings, sites, or other structures should be at least fifty years old. Physical status can be decisive: the William G. Pomeroy Foundation, which funds markers in New York, strongly prefers applications for buildings and homes that still exist or remain actively used, and states plainly that if the structure no longer exists, the application will not be successful.

Documentation requirements are equally strict. Pennsylvania's criteria call for thorough documentation with photocopies and bibliographies from reliable primary and secondary sources, plus verification of the facts claimed. The Pomeroy Foundation requires that claims about noteworthy figures interred in a cemetery be proven with primary sources, and it welcomes applications for unmarked or abandoned cemeteries lacking signage. For schools, the foundation looks for historical significance to the larger community beyond serving one portion of a district, and it encourages applications that prove a noteworthy individual attended.

Historical Marker Eligibility Self-Assessment Framework

Before investing in a full nomination, test your subject against the four dimensions that recur across these programs. The matrix below synthesizes the common criteria; use it to locate your proposal's strengths and its gaps.

Self-assessment matrix for a proposed historical marker subject
Dimension	What programs typically require	If your subject falls short
Historical significance	Statewide or national impact on its times; purely local or regional stories may qualify only under local programs or as exceptional cases	Consider a county or municipal marker program, as Virginia communities like Arlington County and the City of Fairfax maintain
Age of subject	Events generally at least 25 years past; buildings and structures generally at least 50 years old	Wait until the anniversary threshold passes, or document an earlier associated event
Verifiability	Reliable primary and secondary sources, a bibliography, and copies or excerpts of the sources themselves	Gather archival documents, photographs, books, and oral histories before applying
Physical status	Existing or actively used structures are strongly preferred; vanished buildings are commonly disqualified	Refocus the topic on the site, an associated person, or a surviving feature

Work through the rows in order. A subject that clears significance but lacks documentation is a research project, not a rejection; a subject that fails the age or physical-status rows may need a different framing. The goal is an honest early verdict on whether your proposal aligns with typical program requirements, so you can direct effort where it will count.

The Step-by-Step Application Process

Most programs follow the same sequence, even when the deadlines differ. Pennsylvania's process illustrates the pattern: a pre-application form due April 1, followed by a final application due June 1. The pre-application is the first step in determining whether a subject meets the criteria and is an eligible candidate; staff then provide technical assistance and feedback on research for the final nomination. Kentucky runs a similar competition, in which receiving a nomination packet is not formal approval of a topic but simply the ability to advance to the next step, with completed packets postmarked by April 1 for review.

The first move, though, happens before any form. Pennsylvania's marker program staff recommend discussing a proposed topic early, noting that it is helpful to talk with staff "prior to spending the time and effort to research and compile a nomination that may not meet the established Approval Criteria." They receive many good applications each year, and some are not approved. That early consultation is the cheapest insurance available against a wasted season of research.

After a pre-application is encouraged or approved, the research phase begins. A South Carolina preservation toolkit guide instructs applicants to begin collecting archival documents, other primary source documents, photographs, books and secondary sources, and oral histories, while reading the program's criteria packet and application form closely enough to get questions answered in advance. Pennsylvania then requires a significance and documentation worksheet, completed based on pre-application feedback, with digitized copies or relevant excerpts of sources and a bibliography gathered into a single PDF for submission through the state's PA-SHARE system.

The final stage is commission review. In Pennsylvania, the full application undergoes staff review and presentation for a decision; in Delaware, the Director and State Archivist of the Delaware Public Archives issues final approval of the marker text. Expect the reviewing body, not the applicant, to shape the final inscription language, since programs like Georgia's construct marker text to connect local stories to the larger historical narrative.

Essential Logistical Considerations for Your Marker Project

Approval is not the finish line. Georgia requires, among its application elements, a signed easement from the property owners of the proposed marker site and a signed agreement from the sponsoring organizations, along with images of the marker subject and the proposed installation site. Permission must be secured before a marker can be placed on private property, so identify ownership early.

Location deserves its own deliberation. The South Carolina toolkit poses two key questions: is the spot publicly viewable, easy to approach and read, and close to the historical site; and is the property privately owned? The best markers, that guide notes, draw people's attention to find out more about the place they are connected to, even when the marker cannot sit exactly where the history happened.

Finally, plan the dedication. The toolkit encourages applicants to think about what the reveal will include, whether a ceremony, blessing, or consecration; whether alumni, descendants, or community members will speak about the place's importance; and whether guided tours of the site will be offered. Delaware's program asks applicants to act as the point person for receiving and communicating feedback to archives staff, which means the sponsoring group, not the state, typically carries the logistical load for the celebration.

Next Steps: Preparing Your Historical Marker Proposal

Proceed with detailed research and application preparation if your subject meets the general eligibility criteria and you can secure necessary permissions. That means your topic clears the significance, age, documentation, and physical-status dimensions above, and you have identified the property owner whose signed easement or agreement the program will require. If any row of the self-assessment is unresolved, resolve it first, because a complete packet is what commissions actually review.

The measurable indicator of progress is concrete: successful submission of a complete application packet, including property owner permission, and receipt of confirmation from the historical commission. Pennsylvania applicants can track that milestone against the April 1 pre-application and June 1 final application deadlines; Kentucky applicants, against the April 1 postmark. Whatever your state, that confirmation is the moment your neighborhood's story officially enters the review pipeline, and the marker text that emerges will carry your research to everyone who stops to read it.
