About Us
In 1971 the Legislature established the Maine Historic Preservation Commission to implement State policy to "preserve the architectural, historic and environmental heritage of the people of the State, and to develop and promote the cultural, educational and economic benefits of these resources." The Commission is an independent agency within the Executive branch of state government that functions as the State Historic Preservation Office.
Its Director serves as the State Historic Preservation Officer (SHPO) upon appointment by the Governor. The office administers the programs of the National Historic Preservation Act of 1966 in Maine, which includes the identification, evaluation, and protection of the state’s significant cultural resources.
Historic Preservation Grants
The Commission anticipates awarding approximately $90,000 in matching grants for Historic Preservation projects sponsored by Certified Local Governments. Eligible projects include architectural or archaeological survey, public education, preservation planning, National Register nominations or development or pre-development projects. The minimum grant award is normally $10,000 and all grant funds require a minimum 25% non-federal match.
Eligible historic buildings and sites for development and pre-development projects are those that are listed in the National Register of Historic Places either individually or as contributing resources in a National Register-listed historic district. Projects must be directed by persons with professional credentials as defined by the Department of the Interior.
Funding priorities for this round of grants include establishing trades training programs; providing planning assistance to CLG communities; diversifying identification and registration efforts to include everyone’s history; identifying and providing protection for particularly vulnerable resources; supporting pre-development, development and archaeology projects; and increasing awareness of historic preservation activities through education, outreach, publications and events. A complete list of funding priorities is available in the manual.
Historic Preservation Grants are 75:25 % matching grants for architectural or archaeological survey or development or pre-development projects. Grants range between $10,000 and $30,000. Eligible properties must be listed in the National Register of Historic Places and eligible applicants are limited to state agencies, county governments, municipal governments, educational institutions, and private non-profit institutions as defined by the Internal Revenue Service. The source of the funds is the Federal HPF and applications are generally available in the late winter.
Maine Office of Community Affairs
The Maine Office of Community Affairs (MOCA) was established by the Maine State Legislature in 2024 as a one-stop-shop to assist municipalities, Tribal governments and regional planning organizations in building a more resilient future.
In spring 2025, MOCA introduced a newly established State Resilience Office and staff to lead cross-agency efforts to enhance climate resilience across the state, especially in communities with significant climate vulnerabilities impacting residents, infrastructure, and the environment.
Shore and Harbor Planning Grants
The Maine Office of Community Affairs’ Maine Coastal Program (MCP) and Municipal Planning Assistance Program (MPAP) are seeking applications for coastal planning grants totaling approximately $550,000. The two grants covered by this announcement are the Shore and Harbor Planning Grant and the Coastal Community Grant. Funding for these planning grants comes from the Maine Coastal Program’s annual grant from the National Oceanic and Atmospheric Administration (NOAA).
Program Goals
The Shore and Harbor Planning Grant program provides resources on a competitive basis for shoreline access planning, waterfront and harbor planning, identification and resolution of waterfront use conflicts, and planning, feasibility, and design efforts for resilient waterfront infrastructure. Shore and Harbor Planning Grant projects are often well prepared to compete for construction funding through other sources.
